April 13th.历史类第一篇 dance.舞蹈。
Listen to talk about a program answer the student organization.
Good evening ,My name is Pam Jones, and (on behalf of ) the Morden dance club,I'd like to welcome you to tonight's program.The club is pleased to present the TV version of the Catherine Wheel.Twyla Tharp's rock ballet.This video version of the ballet,has been even more successful with audiences than the original theater production,It includes some animation,slow motion,and stop-action freezes that really help the audience understand the dance.
The tile of the piece refers to Saint Catherine,who died on a wheel in 300AD.Nowadays,a Catherine wheel is also a kind of firework,it looks something like a pinwheel. Anyway the dance is certainly full of fireworks! You'll see how Twyla Tharp explores one family's attempt to confront the violence in mordern life.The central symbol of the work is pineapple.But exactly what it presents has always created a lot of controversy.As you watch, see if you can figure it out.
The music for this piece is full of the rhythmic energy of rock music,It was composed by David Byrne,of the rock band talking hands?And the lead dancer in this version was Sara Rudner ,who is perfectly suited to Tharp's adventurous choreography.
Following the video, dance teacher Mary Parker will lead a discussion about the symbolism Ms.Tharp used.We hope you can stay for that,so enjoy tonight's video,and thank you for your support.
Apriel 13th.历史类第二篇Monticello
Before starting our tour of Monticello,I'd like to give you some historical facts that might help you appreciate what you see today even more.
Monticello was the very much loved home of (Thomas Jefferson) for over fifty years.Jefferson,who was ,of course,president, was also a great reader and langauage enthusiast.He read widely on different subjects including architecture.He wasn't formally trained in architecture,but as a result of his study and observation of other buildings,he was able to help design and build the house.He chose the site himself,naming the estate Monticello,which means "little mountain" in Italian.In fact ,many of the ideas behind the design also came from the Italian architect Andrea Palladio.who lived in sixteenth century and who had a great influence on the architecture of England.
Jefferson ,however ,ignored one of Palladio's principles that is not to build in a high place.Monticello's elevation made the transportation of what was needed at the house.For example, food,especially difficult.But the view from the estate without spectacular if Jefferson had followed Pallodio's advice; there really is no boundary between the house and the nature around it,and So Jefferson was able to look out on his beloved state of Virginia from his wonderful adventage point.
Now we'll go on to Jefferson's library.

Welcome to the Four Winds Historical farm , where traditions of the past are preserved for vistors like you. Today ,our master ['mɑ:stə] thatches will begin giving this barn [bɑ:n] behind me a sturdy thatched roof able to withstand heavy winds and last up to a hundred years.How do they do it ? well, in a nutshell,thatching involves covering the beams or rafters ['rɑ:ftə] . the wooden skeletonof a roof,with reeds[ri:d] and straw [strɔ:] .Our chatches here have harvested their own natural materials for the job.The bundles ['bʌndl] of water reeds you see lying ['laiiŋ]over there beside the barn [bɑ:n].
Thatching is certainly uncommon in the united states today.I guess that's why so many of you have come to see the demonstration[,deməns'treiʃən] .But it wasn't always that way.In the seventeenth century,the colonists['kɔlənist] here thatched their roofs with reeds and straw,just as they had done in England.After a while , though, they began to replace the thatch with wooden shingles['ʃiŋglz] because wood was so plentiful ['plentiful].And eventually,other roofing materials like stone ,slate [sleit] ,and clay tiles[tail] came into use.
It is a real shame that most people today don't realize how strong and long lasting a thatched roof is.In Ireland['aiələnd] ,where thatching is still practiced,the roofs can survive winds of up to one hundred ten miles per hour.That's because straw and reeds are so flexible.They bendbut don't break in the wind like other materials can.Another advantage is that the roofs keep the house cool in the summer and warm in the winter .And then,of course,there's the roofs' longevity[lɔn'dʒeviti] ,the average is sixty years, but they can last up to a hundred.With all these reasons to start thatching roofs again.wouldn't it be wonderful to see this disappearing crapft[krɑ:ft] return to the popularity?

A lot of people in United States are coffee drinkers.Over the last few years, a trend has been developing to introduce premium['primjəm] , specially blended coffees-know as"gourmet['guəmei]coffees" into the Amercian market。
Boston seems to have(弱读) been the birthplace of this trend.In fact,major gourmet cooffee merchants from other citie like Seattle[si'ætl] ,San francisco came to Boston.Where today ,they're engaged in a kind of "coffee war" with Boston's merchants. They are all competing for a significant[sig'nifikənt] share of the gourmet coffee market.
Surprisingly,the competition among these leading gourmet coffee will not hurt any of them.Experts predict that the gourmet coffee market in the United Sates is growing and will continue to grow,to the point that the gourmet coffee market will soon capture['kæptʃə] half of what is now of one point five million dollor market.And will be an eight million dollor market by 1999.
Studies have(弱读) shown that coffee drinkers who convert to gourmet coffee seldom go back to the regular brands found in supermakets.As a result,these brands will be the real losers in gourmet coffee competition .

You may remember that a few weeks ago,we discussed the question of what photography is.It is art,or is it a method of reproducing images.Do photographs belong in the museums or just in our homes.Today i want to talk about a person who tried to make his professional life an(听成and) answer to such questions.
(Alfred Stieglitz) went from the United States to Germany to study engineering. While he was there, he became interested in photography and began to experiement in camera.He took pictures under conditions that most photographers considered too difficult.He took them at night ,in the rain,and of people and objects reflected in windows.When he returned to United States,he continued this revolutionary['revə'lu:ʃənəri] efforts(n. 努力).Stieglitz was the first person to the photograph skyscrapers,clouds and views from an airplane.
What Stieglitz was trying to do in these photographs was what he tried to do throughout his life.Make photography an art.He felt that photography could be just as good a form of self-expression['selfiks'preʃən] as painting or drawing.For Stieglitzh ,his camera was his brush.For many photographers of the late 1800's and early 1900's,thought of their (work as连读) a reproduction of identical imagines,Stieglitz saw his as a creative art form,he understood the power of the camera to capture the moment.In fact ,he never retouched his prints or made copies of them. If he were in this classroom today,i'm sure he'd say,"well,painters don't normally make extra copies of their paintings ,do they?"

April 16th 历史类第六篇 人物。
Listen to a student report in the United Stated histrory class.
So as jim said, James polk was eleventh president, well ,my report's about the next president (Zachary ['zækəri] Taylor ['tælən] . 人名)
Taylor was elected in 1849,It is surprising ,because,well ,he was the first president that didn't have any previous['pri:vjəs] political experience. The main reason he was chosen as a candidate was because he was a war hero.
In the army,his men called him "Old Rough and Ready"... I guess because of this rouph edges[edʒ].He was kind of blunt and didn't really look like a military hero.He liked to do things like wear civilian[si'viljən] clothes instead of uniform even in bettle.And he was so short and plump he had to be lifted up onto (注意连读)his hourse.But he did win a lot of battles and he became more and more popular.So the Whig party decided to nominate him for the presidency.Even though no one knew anything about where stood on the issue.
I couldn't find much about his accomplishments.Probably because he was only in office about a year and a half before he died.But one thing,he pushed for the development of the transcontinental ['trænzkɔnti'nentəl] railroad.Because he thought it was important to form a link with the west coast.There was a lot of wealth in California and Oregon['ɔrigən] from commerce and minerals and stuff.Also,he stablished an agricultural bureau in department of the interior and promoted more government aid to agriculture.
Well that'(s about all i found连读).Like I said, he died in office in 1850 so his Vice president took over and that's the next report. so thank you.

I want to (welcome each连读) and every balloon enthusiast [in'θju:ziæst] to Philadelphia [,filə'delfjə]费城.Thank you for coming here this morning to commemorate[kə'meməreit] the first ballon voyage in the United States.On January night,1793 at ten o'clock in the morning, a silk ballon lifted into the skies above this city. Which as the time the capital of the country.
According to the original records of the flight,the voyage lasted forty-six minutes.From its Departure in Phliadephia to its landing cross the Delaware['deləwєə] River in New Jersey ['dʒɜ:zi.Though our pilots today will try to approximate the original landing site.They'reat the mercy of the winds, so who knows where they'll drill off to.Even the baloonist in 1793,experienced some uncertain weather that day.There were clouds, fog, and mist in various directions.
Our reenactment[,ri:i'næktment]promises to be nothing less than spectacular [spek'tækjulə] .The yellow balloon directly behind me is five stories hall.It is inflated[in'fleit] with helium['hi:ljəm],unlike the original, which was filled with hydroen['haidrəudʒən] ,And, unbeknownst ['ʌnbi'nəunst] to the pilot,potentially explosive.
Gas filled models are pretty uncommon now because of the extremely high cost,So the eighty other balloons in today's launch are hot air,heated by propane['prəupein] burners.Theses balloons are from all over the country.

Apriel 18th. campus
LIsten to a talk about medical profession.
It seems like only yesterday that i was siting where you are,just finishing my first year of medical school.And Wondering if i'd ever get a chance to use all my new knowledge on a real life patient.
Well i have good news for you.You don't have to wait until your third or fourth year of medical school to get some hands-on experience.The dean has invited me here to tell you about the university's rural opportunity program.If you enrolled in this program,you can have the oppertunity this summer.After your first year of medical school.To spent from 4 to 6 weeks observing and assisting a real physician like me in the small rural community.You won't have to compete with other students for (time and attention连读).and you can see what life as a country doctor is really like.
The program was designed to encourage medical students like yourslves(听成yourself) to consider careers in rural communities that are still understaffed.It seems that medical students are afraid to go into rural family practice for two reasons .First ,they don't kown how much about it.And second,specialists in the cities usually make more money.But on the up side ,in rural practice, doctors can really get to kown their patients.And be respected members of the community.
I practised in the program when it first started and Spent six weeks small rural town. Let me tell you ,it was really great.I got to work with real patients.I watched the birth of a child,(assisted an accident连读)victim(没有e).And had lost of really practice hands-on experience all in one summer.To my surprise,I found the country life has a lot to offer that city life doesn't.No pollution and traffic jams for instants.
My experience made me want to work where I'm needed and appreciated.I don't miss the city at all.
In a few minutes that remian of today's class,I would like to discuss next week's schedule with you.Because I'm presenting a paper(发表论文) at a conference in Detroit on Thursday.I won't like be here for either Wednesday‘s or Friday's class.I will ,however, be here for Monday's.Next Friday , a week from today is mid-term exam.Marking the halfway point in the semester.Profe ssional (Andrews) has agreed to administer the exam.In place of the usual Wednesday class,I'd arranged an optional review session.Since it is optional,attendance will not be taken.However,attending the class would be a good idea for those worried about the midterm.So remember optional class next Wednesday.MIdterm Friday.
I need make sure you understand how to get housing for next year.When you entered as first year student this year,the school assigned you to a dorm and a roommate.But next year, as returning students .you'll chose both your roommate and your dorm.But whether or not you actually get to live in your first choice depends on what number you or your roommate draws in a lottery system.The system gives priority to the students who have been here longest.Fourth(中间有U) year students get the first block of numbers.third year get the second block,and second year like you'll be get the third.The lower the number you draw, the sooner you choose.NO.1 gets the first choice,NO.2 gets the second choice and so on.
You can use either your own or your intended roomate's number to make your room choice. If your roommate for next year has been at the school longer than you have,they'll be in better block numbers.And so will have a better number than any(听错) second year student.But most of you will probably be rooming(room in听成) with other second-year students and so neither of you have great number.You may not get into your first or even second choice.Of course ,If you've made plans to live off campus you don't enter the lottery at all.
Dorm space will be(没听出) especially tight this year because the dorms on North campus will be closed for renovations.
This means that those of you who draw the worse numbers won't be able to get the dorm housing at all.In that case,the housing office will help you find off campus housing.
Good afternoon.I am here today to talk to you about a career with our airline.We're specially interested in recruiting[ri'kru:t] people to fill openings for flight attendants[ə'tendənt] .
First of all,to work as a flight attendant with us ,you must be accepted into our training program.And with so many people applying, is not easy to be selected.From thousands of (applications没有反应过来)that we receive annually.We choose fewer than a thousand pepole from training.So we require experience serving the public;and it also helps if you've earned some college redits.
Also not everyboy who gets accepted into the training program makes it through.
The course meets six days a week for five weeks.The training includes extensive classroom work in such subjects as first aid and passenger psychology(乘客心理学) as well as practical training in flight procedures(过程)[prə'si:dʒə] and meal service.A lot of our graduates say that our fight attendants develop the skills of nurse.a headwaiter and a public relations executive[ig'zekjutiv] ..
But as fight attendant myself i can say that all of the hard work is worth it . Of course, I get to travel throughout the country,and the airline pays all of my expenses while I'maway from my base station. What i like (best of all is连读) that I've made with friends all over the country.

Listen to the part of lecture in the museum.
Let's proceed to the mainly exhibit hall and look at some of the actual vehicles ['vi:ikl] that have played a prominent role in speeding up mail delivery.Consider how long it used to take to send a letter across a relatively ['relətivli]short distance.Back in the sixteen hundred's,it took two weeks on horseback to get a letter from Bosten to New york,a distance of about 260 miles.Crossing the river was also a challenge. Ferry service was so irregular that a carrier would sometimes wait hours just to catch a ferry.For journeys island, there was always the stagecoach['steidʒkəʊtʃ] ,but the ride was by no means comfortable because it had to be shared with other passengers.The post office was pretty ingenious[in'dʒi:njəs] about some routes.In the 19th century in the southwestern deserst ,for instance. camels['kæməl] were brought in help get the mail through. In Alaska,reindeer ['reindiə] were used.This practice was discontinued because of the disagreeable temperament of these animals.
we'll stop here a minute so that you can enter this replica['replikə] of a railway mail car(而非是card).It was during the Age of the Iron Horse that delivery really started to pick up. In fact,the United States transported most bulk[bʌlk] mail by train for nearly one hundred years.The first airmail service didn't start until 1918.
Please take a few moments to look around,I hope you'll enjoy your tour.And as you continue on your own, may I suggest you visit our impressive(a. 给人深刻印象的) (philatelic[filə'telik] collection..集邮品).Not only can you look at some of the more unusual stamps issues, but there is an interesting exhibit on how stamps are made

Listen to a part of lecture in philosophy[fi'lɔsəfi] class.
Ok,Another ancient Greek philosopher we need to discuss for (Aristotle人名 n. 亚里斯多德) Aristotle's ethical['eθikəl] theory . What Aristotle's ethical theory is all about is this. He's trying to show you how to be happy-What ture happiness is.
Now ,why is he interested in human happiness,it is not just because it's something that all people want or aim for. It is more than that . But to get there we need to first make very important distinction[dis'tiŋkʃən].Let me introduce a couple of technical tearms: extrinsic[eks'trinsik] value and intrinsic[in'trinsik] value.
To understand Aristotle's interest in happiness, you need to understand this distinction.
Something we aim for and value, not for themselves but for what they bring about in addition to themselves.If I value something as a means to something else ,then it has what we will call 'extrinsic value'.Other things we desire and hold to be valuable for themselves alone.If we value something not as a means to something else.But for its own sake ,let us say that it has intrinsic value.

Listen to a professor talk to his city claiming class.
Today we'll examing the role that private transportation namely,the automobile ['ɔ:təməbi:l] --(plays in连读) city planning(复数需要双写n).
A number of sociologists blame the automobile for the decline of the downtown areas of major cities.In the 1950's-1960's,the automobile made it possible to work in the city and yet live in the suburbs ['sʌbə:b] many miles away.Shopping patterns changed,instead of patronizing['pætrənaiz] downtown stores.People in the suburbs went to large shopping malls outside the city closer to home. Merchants in the city failed(非field),and their stores closed.Downtown shopping areas became deserted.
In rencent years there's been a rebirth [ri:'bə:θ] of the downtown areas, as many suburbanites [sə'bə:bənait] have moved back to the city.They've done this, of course,to avoid highways clogged[klɔg] with commuters[kə'mju:tə] from the suburbs.
I've chosen this particular city planing problem.Our dependence on private transportation to (discuss in连读。。) groups. I'm hoping you all will come up with some innovative solution. OH and don't approach[ə'prəutʃ] the problem from a purely['pjʊəli] sociological perspective(社会学的透视).Try to into account environmental and economic issues as well.

Bofore we begin our tour,I'd like to give you some background information on the painter grant wood,we'll be seeing much of his work today.
Wood was born 1881 in Iowa farm country,and became interested in art very early in life.Although he studied art in both Minneaolis(城市名)and at the art institue of Chicago.The strongest influences on his art were European.He spent time in both Germany and France.His study there helped shaped his own stylized['stailaiz] form of realism['riəlizəm].
When he returned to Iowa,wood applied the stylistic[stai'listik] realism he had learned in Europe to the rural life he saw around him and he remembered from his childhood around the turn of the century.***His portraits['pɔ:trit] of farm families imitate['imiteit] the static formalism of photographs of early settlers posed in front of their homes.***难句。。His paintings of farmers at work and of their tools and anmials.Demonstrate['demənstreit] a serious respect of the Midwestern United States.
By the1930's, wood was leading figure of the school of art called "American regionalism ['ri:dʒənə,lizəm]".
In an effort to sustain a strong midwestern artistic movement. Wood established an institue of Midwestern art in his home state.Altough the institute failed,the painting you are about to see preserve Wood's vision of pioneer farmers.

Before we start our third lab,I'd like to tell you a little bit about the workbook we'll be using.
The first thing I'd like to point out(听成down) is that the workbook contains a very large amount of material.Far more than you could ever handle in a single semester.What you're supposed to do is choose the experiments and activities that you want to do, within a certain framework['freimwə:k] ,of course,Part of my job is to help you make your choices.
Next I'd like to mention that in each workbook chapter,there are usually two subsections.The first is(连读) called experiments,and the second is(连读) called activities.
In the "experiments" section, the workbook gives full(听错) instructions for all the experiments,including his alternate procedures[prə'si:dʒə] .Choose the procedure you wish,there's plenty of equipment available[ə'veiləbəl].
In the activity section,you will find suggestions for projects that you can do on your own time.You'll see that there are usually no detailed instructions for the activities.You're supposed to do them your own way.
If there are no questions,let's turn to chapter one now.

Word comes from California of a new weapon in the war on household pests.Two scientists working for afirm in (Anaheim地名), California,have developed a method to eliminate insects without using dangerous chemicals.The new poison?Hot air.
The basic(听成best) idea is that insects can not adjust to temperatures much above(听成about) nomoral.In laboratory experiments,cockroaches and termites can't survive much more than a quarter of an hour at 125 degrees Fahrenheit, or about 50 degrees centigrade.
The new method involves covering a house with a huge tent and filling with air heated to around 65 degrees centigrade.Hot air is forced in with fans,and the tent keeps the heat inside the house.Since termites try to escape by hiding in wooden beams(房梁),the heal treatment must be continued for a full six hours.But when it's all over,and the insects are dead.There was no toxic['tɔksik] residues['rezidju:] to endanger humans or pets,and no funny smells.
Scientists claim that there is no danger of fire, either, since very few household meterials will burn at 65 degrees centigrade.In fact,what is prepared for construction use by drying it ovens at 80 degrees centigrade which is substantially[səb'stænʃ(ə)li] hotter than the air used in this procedure.
To us, the environment in which fish dwell often seems cold,dark,mysterious. But there are advantages to living in water. And they have played an important role in making fish what they are.One is that subject to sudden temperature changes.Therefore it makes an excellent habitat for a cold-blooded animals.Another advantage is the water's ability to easily support body weight.Protoplasm ['prəutəplæzəm]has approximately the same density as water.So a fish in water is almost weightless.This "weightlessness" in turn means two things.One,a fish can get alone with a light weight ,and simple bone structure.And two,Limitations to a fish's size are practically removed.
Yet, there is one basic difficulty to living in water,the fact that it's incompressible[,inkəm'presəbl] .For a fish to move through water,It must actually shove [ʃʌv] its aside.Most can do this by wiggling back and forth in snakelike motion.The fish pushes aside by forward motion of its head,and with the curve of its body and its flexible tail.Next, the water (flows back) along the fish's narrowing sides, closing in at the tail ,and helping the fish to propel itself forward.
(The fact the water is incompressible has literally shaped development of fish.)A flat and angular(又尖角的) shape can be moved through water only with difficulty.And for this reason ,fish have a basic shape beatifully adapted to deal with this peculiarity.

LIsten to a museum gay described one of museum exhibits
We've just seen(时态问题) two contemporary large birds that they can not fly:the emu['i:mju:] and ostrich[' ɔstritʃ] .Over here is an interesting specimen ['spesimən]from the past.This stuffed animal is not the giant penguin ['peŋgwin] it appears to be,but an auk.This perticular kind of auk is very rare(词的识别),only 78 skins are known【not听错】 to exist and most of them not preserved as well as this one.The great auk ,you can see,was a rather large bird,and it couldn't fly either.However ,evidence suggests that the auk was an excellent swimmer and diver.
Unfortunately ,those abilities did not protect it from being easy prey for hungry sailors who years ago sailed the very cold and ofen icy waters of Greenland Iceland,Scotland.In fact ,records indicate that the auk was rather tasty and that its eggs. That its eggs and feathers were useful as well,still,it isn't clear what other factors led to the big bird's demise [di'maiz] around 1844,the last time anyone reported seeing one.Of course,we believe it's important to take extra precautions [pri'kɔ:ʃən] to preserve the remaining great auk skins. After all ,these specimens should prove invaluable for future scientific resarch.Does anyone have any questions before we have next bird exhibit?

Tyrannosaurus [tirænə'sɔ:rəs] rex 霸王龙
Before I tell you about the interesting discovery related to Tyrannosaurus rex ,I need to review something we studied last semester. The difference between what are commonly called cold-blooded and warm-blooded animals. In warm-blooded animals, bird and mammals ,for example, the body temperature normally stays within narrow range. No matter what the outside temperature is. As a result, a warm-blooded animal is usually active in both cold and hot weather.Because its body temperature can adjust to the temperature of its environment.
On the other hand, cold-blooded animals, such as most reptiles['reptail] ,amphibians[æm'fibiən] and insects. are unable to create enough heat internally to raise their body temperature above the temperature of the environment.so,for example,the temperature of a cold-blooded animal falls when the environment is cool.
I hope this distinction is clear, now moving(听成move it) on to Tyrannosaurus rex, you may know that dinosaurs been reptiles ,are generally believed to have been cold-blooded. Well, a recent research study found that the chemical composition of the bones of tyrannosaurus rex was consistent with the bones of an animal that has a very narrow range of internal temperature, indicating that it was probably warm-blooded.

This room is devoted to electric fish. The eel [i:l] in the tank(池塘) behind me can produce a jolt of electricity to stun its prey. But most of the fish in here produce only weak electrical impulses that useful for the naviating, locating food and even for communicating.
The knife fish is a good example, This fish navigates using tiny receptors[ri'septə] in the skin that are sensitive to electrical impulses .The knife fish produces an electricity signal,and the receptors in its skin let it know when the signal it distorted by a tree root,or some other obstacle['ɔbstəkl], so it can go around it.
Fish also use the ability produce and detect [di'tekt] electrical impulses to communicate.They can tell each other what species they belong to, how big they are ,and whether they're male or female. We have tank here that's specially equipped to convert the inaudible [in'ɔ:dəbl] sinals the fish produce into sounds you can hear when you put on these headphones.I urge[ə:dʒ] you all to listen in when I'm done speaking
Now have a look at the electric rays. Rays is especially interesting to medical researchers because of the organs ['ɔ:gən] they use to produce electricity.
These organs contain a chemical that carries signals from one nerve ending to the next.Not only in rays ,but also in people.By studying these organs,scientists hope to learn more about diseases that interrupt the transmission of impulses, from one nerve to another.

mouse(7)
Human populations near the equate have evolved dark skin over many generations because of exposure[iks'pəuʒə] to the fierce rays of the sun. A similar phenomenon has also occurredin otherparts of aminal kingdom .The African grass mouse(声调) is a good example. Most mice are nocturnal[nɔk'tə:nl],but the African grass mouse is active during daylight hours.This means that (it spends) its days searching for food in the semidry
(adj. 半干性的)bush and scrub habitats of eastern and southern America.Its fur is striped[straipt],Which helps itblend in with its environment.Because It spends a lot of time in the intense[in'tens] tropical sun,the grass mouse has also evolved two separate safeguards against the sun‘s ultraviolet radiation.First like the populations ofhumans in this region of the world,the skin of the grass mouse contains lots ofmelanin['melənin] and dark pigment.Second ,and quiet unusual,this mouse has a layer of melanin-pigmented tissue between its skull and skin.This unique[ju:'ni:k] "cap" provides an extra measure of protection for the grass mouse and three types of African mouselike(像老鼠一样的)rodents['rəudənts] that are active during the day.The only other species scientists have identified with same sort of skull adaption is the white (tent-making bat尾皮蝠) of the Central America tropics.Although these bats sleep during the day,they do so curled up their heads exposed to the sun.

May 5th classification [,klæsifi'keiʃən] of trees.
OK,In the last class we talked about the classification of trees,and we ended up with a basic description of angiosperms.You remember that those are plants with ture flowers and seeds that develop inside fruits. The common broadleaf trees we have on campus fall into this category,but our pines don't.
Now, I hope you all follow my advice and wore comfortable shoes.Because as I said,today we're going to do a field study.
To get started,Let me describe a couple of the broadleaf trees we have in front of us. I am sure you've all noticed this big tree next to (Brant Hall).It's a black walnut ['wɔ:lnət] that must be 80 feet tall.As a matter of fact,there's a plaque indentifying it as the tallest black walnut in the state,and From here we can see the beautiful archway of trees at the commons. They've American elms.the ones along the commons were planted when the college were founded a hundred and twenty years ago.They have the distinctive dark green leaves that look lopsided ['lɔp'saidid] Because the two sides of the leaf are unequal(不规则的).I want you to notice the elm right outside just jackson hall.Some of its leaves have withered['wiðə] and turned yellow ,maybe due to Dutch elm disease.Only a few brances seem affected so fast.But if this tree is sick,it'll have to be cut down.
Let's move on and I'll describe what we see as we go.

Today I want to talk to you about wasps and their nests.You'll recall that biologists divide species ofwasps into two groups:solitary and social。
Solitary wasps,as name implies ,do not live together with other wasps.In most species ,the male and female get together only to mate, and then the female does all the work of buliding the nest and providing food for offspring by herself.Solitary wasps usually make nests in the ground and they seperate the chambers for individual offspring with bits of grass ,stone, or mud ,whatever is handy.
What about social wasps?They form a community and work together to build and maintain the nest.A nest begins in the spring when a fertile female called queen ,builds the first few compartments of the nest and lays eggs.The first offspring are small females that can not lay eggs.These females ,called workers, then build a lot of new compartments and the queen lays more eggs.They also care for the new offspring and defend the nest with their stingers.By the way,only female wasps have stingers.
Most social wasps make nests of paper,the female produce the paper by chewing up plant fibers or old wood.They spread the paper in thin layers to make cells in which the queen lays her eggs.Most of you,I'm sure,have seem these nests,suspended from trees.
They may also be build underground,in abandoned rodent burrows.

Before moving on to a new topic, I want to finish up our unit on arachnids[ə'ræknid] by looking at what may seem a very unusual aspect of spider behavior.a spices where the young spiders actually consume the body of their mother.
Unlike most other spiders ,this spices lays one only one clutch of forty eggs in her lifetime.The young spiders hatch in mid-spring or early summer inside a nest of eucalyptus leaves.Their mother spends the warm summer months bringing home large insects.Often ten times her weight,The catch is always significantly more than her young spider can eat.
So their mother fattens up on this extra prey and stores the nutrients in her extra(unfertilized) eggs.As the weather turn colder, there are fewer insect prey to hunt.That's when the nutrients stored in those extra eggs begin to seep into the mother's bloodstream.So, when there are no more insects to feed to the young spiders, they attach themselves to their mother's leg joints and draw(提取) nourishment by sucking( 吮吸) the nutrients-rich blood.
After several weeks,their mother is depleted of all the nutrients and she dies.But then how do the young get nourishment?They start to feed one another.Now,If you recall our discussion of Darwin.you'll see evolutionary value of this.Only the strongest spiders of the clutch is survive this "cannibalism" and the mother spider will have ensured that her genes have an increased chance of survival through the future generations.

May 10th (生物11) kangaroo[,kæŋgə'ru:] n. 袋鼠
Now we're entering kangaroo country.In all,there are more than fifty different species of kangaroo,and the advantage of zoos like ours is that you see them in their natural habitat.The ones we have all live in the grasslands.
On my right ,you can see one of the biggest types: the red kangaroo.It travels about twenty miles per hour.It looks like hard work,but hoping acturally lets the kangaroo conserve more energy than another animal could when running on four legs. In fact,up to a certain point ,the faster a kangaroo goes the more energy it conserves.Rather than taking more hops to increase speed, the kangaroo makes the length of each jump longer.
Let's stop here for a minute.Take a look over on your right at this group of kangaroos resting.Can you see their ears are moving?Hearing may well be the kangaroo's most important sense.Their two large ears can move independently,so sometimes one ear is pointing forward and the other toward rear.Kangaroo's eyesight is also excellent.They have a wide field of vision and,like most grazing animals.They are specially good at detecting movement.
Before we move on ,I'd like to point out one more thing.If you look closly,you can see a joey---That's a baby kangaroo.Peering out of its mother's pouch.Before long that joey will be out of the pouch for good,the mother will push it out by the times eight months old.

If you liked the colorful animal we just saw, you're going to love these next animals,frog.You might not normally think of frogs as being colorful,but these frogs definitely are. They are the dart-poison frogs of central and south America.Look at their striking colors--- often yellow with black stripes or deep blue with black spots.
Beyond being nice to look at,these marking have a purpose.They warn predators that these frogs are poisonous.When threatened,these frogs secrete a substance through their skin that would easily kill whatever animals might try to eat them .Their bright colors communicate this.and so most animals tend not to hunt them.
Now speaking of hunting,for centuries these frogs sought after by hunters.As you might think, the hunters didn't want to eat the frog,for rather, they captured抓获 them for their poison.They would add the poison to the tips尖端 of their hunting arrows箭 ['ærəu].Of course,nowadays most hunters use guns.
These days dart-poison frogs are of less interest to hunters than to medical researchers.Researchers believe that they can make new heart medicine from the poison.Because it acts stimulate on the body's nervous system.Research think they could use it to stimulate a weak heart.
There is, however, a problem with doing a research on these frogs. (Those that are caught in the (wild)文章错误!! will produce their poison until they die.)However, those that are born in captivity,like the ones you see here, will not produce any poison at all.

As Dr.Miller mentioned,we're trying to recruit volunteers for the Hawk mountain sanctuary.But before I get into the details of the volunteer program,I'd just like to tell you a little about what we do there.
One of our main jobs is to keep detailed records of the migration patterns of raptors.For those of you who don't know,raptors arebirds of prey, like hawks and eagles.Between Augest and December,we see around twenty different species migrating from Canada and New England,about twenty-thousand birds.
Part of what attracts them to Hawk motain is the location on the east ridge of Appalachian(adj. 阿帕拉契山脉的) mountines.What happens is that the sun warms the ridge in such a way that air currents are formed.The birds just sort of glide along on the air.So they use up very little energy.
As volunteers you'll be helping us keep accurate counts of the raptors. Any drop in number could mean something's gone wrong in the environment.Because of pesticides or disease even hunting.
we just had a scare with the broad-winged hawks.Their numbers have dropped drastically over the last ten years.It was suggested that the birds may have changed their migratory route.So for 11 days,we had several hundred volunteers stationed every five miles.To observe and count.And sure enough,they discovery that instead of hugging the Appalachians as they'd always done ,the broad-wings were cutting a wide path over the Delaware River.Needless to say,we were greatly relieved.
