听力原文： Do you know that there's a kind of bird that can sew？ This bird, called the tailorbird, uses its mouth as a needle. It sews leaves together in a shape of a cup. Then it adds a layer of straw to the inside of the cup and lays its eggs there. Each bird species builds its own special kind of nest. The most common materials used for nests are grasses, branches and feathers. A bird must weave these materials into a nest. Just imagine building a house without cement or nails to hold it together. Another bird is called the weaverbird. The weaverbird builds a nest that looks like a basket. The nest is shaped like a pear with a hole in the middle. The hole is the door of the nest. The third bird is called the ovenbird. The ovenbird makes a nest that is very solid. The nest is made of mud. The ovenbird forms the mud into the shape of an oven and then lets it dry in the sun. The sun bakes the mud, making it very hard. Not all birds make their homes in branches. Some birds build their nests on the ground, while others bury their eggs under the ground. And some birds do not build nests at all. So when you look for nests and eggs in the branches of trees and bushes, remember, that some nests may be right under your feet.

To: All department managers
From: Molly Stuart
Date: 16 October 2009
Subject: In-service English classes
C.C: Dallen Hook, the general manager
From Monday 2 November English classes will be held in the Training Center (Room 317). There will be two groups: intermediate level (8 : 30 — 10 : 00 a.m.) and advanced level (10 : 30— 12 : 00 a. m.). Please encourage your staff to attend one of the sessions. All teaching materials will be provided but students will be expected to do homework and preparation outside working hours.
Please send me the names of all interested staff by noon on Wednesday 21 October. They will be given an informal oral test during the last week of October so that we can decide which of the classes is best for them.
The size of each class will be limited to 12 participants.
What is the main purpose of writing this memo？
A．Enrolling students for an advanced English class
B．Informing department managers of the opening of in-service English classes
C．Asking all department managers for proposal on in-service classes
D．Reporting the information of in-service classes to Dallen Hook
You will hear five short recordings.
For each recording, decide what advice the speaker is giving.
Write one letter (A-H) next to the number of the recording.
Do not use any letter more than once.
After you have listened once, replay each recording.
A. begin and end the talk well
B. rehearse a few times beforehand
C. use clear visual materials
D. maximize eye contact with the audience
E. check all equipment thoroughly
F. look smart and business-like
G. avoid talking for too long
H. get the audience to participate
听力原文：M: Excuse me. I wonder if you could help me.
W: What can I do for you？
M: Well, I'm working on a term paper about the influence of television on American presidential elections.
W: Have you ever been to the main library？
M: Yes, I've found a few useful books there, but the reference librarian at the main library suggested that the library here at the graduate school have more specialized materials.
W: Okay. It depends on what you want. We do subscribe to a large number of journals. Since you're working on such a broad topic you'll probably have to do a lot of digging.
M: Do you think I can get something relevant here？
W: It may take some time, but you'll be able to find many articles relevant to your topic. We also have quite a few newspapers on microfilm.
M: I think I've come to the right place. How can I find out which journals you have？
W: There's a list of all of them. But if you want to search by author or by subject you can use one of the computers over there. Everything we have is in there.
M: What if I run across a reference to a research study that isn't available here？
W: You can request any outside materials just by typing your request into the computer.
M: You mean you can get materials from other universities？
W: Not only from other universities, but from virtually any public or private library in the United States. The only limitation is that outside materials can't be checked out.
(23)
A．To type some research materials.
B．To learn to use the computers there.
C．To get material not available at the main library.
D．To choose a topic for a term paper.

New Understanding of Natural Silk"s Mysteries
Natural silk， as we all know， has a strength that manmade materials have long struggled to match. In a discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough， MIT researchers have discovered that silk gets its strength from its weakness. Or，more specifically， its many weaknesses. Silk gets its extraordinary durability and ductility from an unusual arrangement of hydrogen bonds that are inherently very weak but that work together to create a strong， flexible structure.
Most materials- especially the ones we engineer for strength- get their toughness from brittleness. As such， natural silks like those produced by spiders have long fascinated both biologists and engineers because of their light weight， ductility and high strength （pound for pound， silk is stronger than steel and far less brittle）. But on its face， it doesn"t seem that silks should be as strong as they are; molecularly， they are held together by hydrogen bonds， which are far weaker than the covalent bonds found in other molecules.
To get a better understanding of how silk manages to produce such strength through such weak bonds， the MIT team created a set of computer models that allowed them to observe the way silk behaves at the atomic level. They found that the arrangement of the tiny silk nanocrystals is such that the hydrogen bonds are able to work cooperatively， reinforcing one another against extemal forces and failing slowly when they do fail， so as not so allow a sudden fracture to spread across a silk structure.
The result is natural silks that can stretch and bend while retaining a high degree of strength.
But while that"s all well and good for spiders， bees and the like， this understandingof silk geometry could lead to new materials that are stronger and more ductile than those we can currently manufacture. Our best and strongest materials are generally expensive and difficult to produce （requiring high temperature treatments or energy-intensive processes）.
By looking to silk as a model， researchers could potentially devise new manufacturing methods that rely on inexpensive materials and weak bonds to create less rigid， more forgiving materials that are nonetheless stronger than anything currently on offer. And if you thought you were going to get out of this materials science story without hearing about carbon nanotubes， think again. The MIT team is already in the lab looking into ways of synthesizing silk-like structures out of materials that are stronger than natural silk—— like carbon nanotubes. Super-silks are on the horizon.
MIT researchers carry out the study to illustrate an ancient Chinese proverb. 查看材料
A.Right
B.Wrong
C.Not mentioned
It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist’s failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing. We can’t judge every modern building by the standards of the ancient time, even though we admire the ancient buildings. Technologically, the modern buildings are more advanced. The modern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past. He is too proud to do that.
Technologically, the modern buildings are more advanced. The sentence means _____.
A.the ancient architects had no technology
B.the modern architects use more advanced technology
C.the modern buildings are advanced because they are completely different from the ancient buildings
D.the modern buildings are more beautiful
Some people hate everything that is modern because _______.A.they are aged
B.they find it hard to accept modern things
C.they take their standards of perfection from the Greek
D.they look at things by the standards of the past
The writer thinks the failure of a building _______.A.means nothing
B.concerns others
C.concerns only the artist
D.concerns all the people in the world
The writer of the passage thinks that ________.A.it is true to say artists fail in their work
B.it is untrue to say artists fail in their work
C.it is true to say some artists fail in their work
D.it is true to say only painters fail in their work
The writer thinks that _________.A.we can’t judge buildings by the ancient standards
B.we can’t judge all the buildings by the ancient standards
C.we can’t judge all the modern buildings by the ancient standards
D.we can’t judge modern buildings
