听力原文:Are you aware that you actually possess six senses? The sixth is a muscular sense

听力原文: Are you aware that you actually possess six senses? The sixth is a muscular sense responsible for directing your muscles intelligently—to the exact extent necessary for each action you perform. For example, when you reach for an object, the sensory nerves linking the muscles to the brain stop your hand at the correct spot. This automatic perception of the position of your muscles in relation to the object is your muscular sense in action.

Muscles are stringy bundles of fibers varying from one five-thousandth of an inch to about three inches. They have three unique characteristics: they can become shorter and thicker; they can stretch; and they can retract to their original positions. Under a high powered microscope, muscle tissue is seen as long, slender cells with a grainy texture like wood.

More than half of a person's body is composed of muscle fibers, most of which are involuntary--in other words, work without conscious direction. The voluntary muscles, those that we move consciously to perform. particular actions, number more than five hundred. Women have only 60 to 70 percent as much muscle as men for their body mass. That is why an average woman can't lift as much, throw as far, or hit as hard as an average man.

(30)

A.It means that one always knows what his muscles are doing.

B.It means that one performs simple actions without working.

C.It means that one's muscles are used only to the extent necessary for each action they perform.

D.It means that one improves muscular action consciously.

听力原文: Clay is found almost everywhere in the world. (32) It is formed by the action of wind and water on rocks over thousands of years. The rocks change in both chemical and physical ways. Chemically, elements are added and taken away. Physically, the rocks break down into smaller and smaller pieces. After a long time, some of the rock changes to clay. (33) Clay is important because it is used around the world to make containers of all kinds. Potters add water to soften the clay. This makes it easier to form. into shapes by hand or by machine. Then it is fired in an extremely hot stove. The result is a container with a hard surface that will last for many years. You can usually find good clay (34) in low areas of islands or land, especially if volcanoes helped form. the land. (34) Clay often exists in fields covered with some water. The clay will be found about one meter below the ground. (34) River banks often also have clay about one meter or less under the surface. You can recognize clay (35) because it is very shiny when it is wet. You can also perform. a test. Take some of the material and add enough water to it to make it seem like you are making bread. Then press it in your hand until it is about the size of an egg. It is probably clay if it holds together instead of falling apart when you stop pressing.

(33)

A.The natural force makes it come into being.

B.It originates from some chemical elements in the nature.

C.It comes from the rocks with the action of wind and water.

D.A series of biological changes happen in the process.

Learning to Keep Your Cool During TestsHave you ever felt so anxious during an examinati
Learning to Keep Your Cool During Tests

Have you ever felt so anxious during an examination that you couldn't even put down the answers you knew? If so, you were suffering from what is known as test anxiety.According to psychologist Ralph Trimble, test anxiety is a very real problem for many people. When you're worried over your performance on an exam, your heart beats faster and your pulse speeds up. These reactions start others: You may sweat more than normal or suffer from a stomachache or headache. Your field of vision narrows and becomes tunnel-like. Before you know it, you're having difficulty focusing."What I hear students say over and over again," says Dr. Trimble, who is working at the Psychological and Counseling Center at the University of Illinois, "is, 'My mind went blank.'"

For a number of years, Dr. Trimble helped many students learn how to perform. better during exams and to bring up their grades. Some of these students were interested in sharing what they learned and, with Trimble's help, began holding workshops on overcoming test anxiety. For many students, just being in a workshop with other sufferers made them feel better. They realized that they were not the only ones who had done poorly on tests because of tension.The workshops were so successful that they are still given.In the workshops, students are taught that anxiety is normal. You just have to prevent it from getting the best of you. The first step is to learn to relax. If before or during an examination you start to panic, stretch as hard as you can, tensing the muscles in your arms and legs; then suddenly relax all of them.This will help relieve tension. But keep in mind that you don't want to be too relaxed. Being completely relaxed is no better than being too tense. "If you are so calm you don't care how you do on an examination, you won't do well," Trimble says. "There is an optimum level of concern when you perform. at your best. Some stress helps. There are people who can't take even slight stress. They have to learn that in a challenging situation, being anxiously excited is good and will help them to do better. But if they call it anxiety and say, 'It's going to hit me again, ' that will make them nervous and worried."

As a student you must also realize that if you leave too much studying until a day or two before the examination, you can't do the impossible and learn it all. Instead, concentrate on what you can do and try to think what questions are likely to be asked and what you can do in the time left for studying.When you sit down to study, set a moderate pace and vary it by reading, writing notes, and going over any papers you have already written for the course, as well as the textbooks and notes you took in class. Review what you know. Take breaks and go to sleep early enough to get a good night's rest before the exam. You should also eat a moderate breakfast or lunch, avoiding drinks like coffee and stay away from fellow students who get tense. Panic spreads easily.Get to the exam room a few minutes early so that you will have a chance to familiarize yourself with the surroundings and get out your supplies. When the examination is handed out, read the directions twice and underline the significant instructions, making sure you understand them. Ask the teacher to explain if you don't. First answer the easiest questions, then go back to the more difficult.On essay questions, instead of starting right away, take a few minutes to organize your thoughts, make a brief outline, and then start off with a summary sentence. Keep working steadily, and even when time starts to run out, don't speed up.

听力原文:W: Why is it that some children perform. much better than others at school?

M: Obviously, certain children are brighter than others, but it's not as simple as that. A lot of emphasis is placed on intelligence measured by tests.

W: The so-called IQ tests?

M: Yes. Basically they are intended to test linguistics and numerical skills, so some children are bound to suffer. This is very unfortunate. A child with an average IQ may turn out to be successful when he grows up.

W: What you're saying is that some children have abilities that are not easy to measure, that aren't appreciated

M: Precisely. And if these skills are not spotted sufficiently early, they cannot be developed. That's why, in my view, there are so many unhappy adults in this world. They are not doing the things they are best at.

W: I see.

M: But at school, only those children who are good with words and numbers, they probably do well in school examinations.

W: Right. Is there anything a parent can do to help in this case?

M: Yes. In my opinion, a child should be judged by his individual talents. After all, being happy in life is putting your skills to good use, no matter what they are.

(23)

A.They are designed to measure children's intelligence.

B.They are intended to test linguistic and numerical skills.

C.They are designed to test why some children perform. better at school.

D.They are intended to find out why some children are not appreciated.

听力原文:Do you have a tough math test coming up? Then listen to some classical piano musi

听力原文: Do you have a tough math test coming up? Then listen to some classical piano music just before the test. You might end up with a higher score (30) . Researchers at a university in California conducted an experiment. They asked a group of college students to listen to some piano music by a famous 18 th century composer before taking a math test. They were surprised to find that the students' scores jumped 8 to 9 points. The music seems to excite nerve activities in the brain (31) ; similar to the activity that occurs when a person is figuring out a math problem. However, the scientists warn that before you get too excited about applying this method to your math test, you should remember that brain-exciting effects lust only 10 to 15 minutes (32) . Would rock music work as well as the piano music do? No, the scientists say. In fact, the less complex music might even interfere with the brains' reasoning ability.

(31)

A.How to improve your reasoning ability.

B.Why classical music is popular with math students.

C.The difference between classical music and rock music.

D.The effects of music on the results of math tests.

听力原文:M: Want to go out and get something to eat?

W: I can't. I have a chemistry midterm on Monday and a German exam on Tuesday.

M: I have a geology exam Monday myself, but I think I'm ready for it.

W: What kind of exam is it going to be—multiple choice or essay?

M: Neither. The professor is going to give us a mineral sample and we have to identify it.

W: How do you do that? I mean, a rock's a rock, isn't it?

M: Actually, there are a lot of tests you can perform. on minerals to help you figure out what they are. Probably the first tests I'll do are scratch tests. When you do a scratch test, you rub the sample on a known mineral to see if the unknown mineral scratches the known mineral or vice versa. That tells you the relative hardness of the sample.

W: What other tests will you do?

M: I'll probably do a streak test next. In that test, you rub an unknown mineral against a piece of china to see what color the streak is.

W: Why can't you just look at the mineral to see what color it is?

M: Well, you can, but sometimes a mineral has some other substance in it, and the substance can change its color. But a streak test shows the mineral's true color. Then there's always the specific gravity test, the blowpipe test...oh, and...

W: And after you've done all these tests, you can positively identify any mineral?

M: Well, usually...but not always. I just hope I can on Monday!

(20)

A.A multiple-choice exam.

B.A chemistry exam.

C.A German exam.

D.A geology exam.

Nowadays, Valentine's Day wins the same popularity among Chinese young people. It is a time when students "don't want to be alone".
