immersed. When you light the end which is not immersed, it will burst into flame. This is because the oil
is able to rise up the lamp wick thus helping it to burn.
In the same way, if you immerse the end of a piece of chalk into a glass of water, the water will soon
climb up the chalk making it wet.
If a piece of ordinary glass tubing is heated in a gas flame until it becomes soft, it can be pull into a tube
of a very small hole. Immerse the tube into water or any other liquid which wets glass, you will find that
the liquid rises to a height of several centimeters. This is known as capillary action. The liquid rises because
there is an attractive force between the liquid and the glass. The attractive force depends on the diameter of
the tube and the type of liquid used.
B. Because there is oil climbing up the wick.
C. Because the other end is immersed.
D. Because the wet end is lighted.
B. water
C. chalk
D. paper
B. the diameter of the tube and the kind of the liquid decide the greatness of the force
C. the thinner the diameter, the smaller the attractive force
D. oil climbs up higher than water
B. the glass has an attractive force
C. the liquid tends to rise up
D. both glass and liquid act on each other
C. liquid climbing up things
D. capillary action

different opinions about where is the best place to live in. Also, the best places to live are not always home
to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute
of Technology, for example, is a great school for computer science and technology-related fields of study.
However, if you want to study oceanography (海洋学), your interests may be better served by attending
school in a place that is on a coastline or near the ocean.
Now I am sure that you know which schools are considered the best in the country. So I will tell you
about which states I believe are the best to live in.
California is a nice state. Northern California specifically has very good weather. Los Angeles in Southern
California is another story though. Life in Los Angeles is full of excitement and fast,and sometimes dangerous.
As for me, I enjoy the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of
history and culture. The weather is not as perfect as California, but it is still quite nice. My favorite area of
America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition,
there are many good universities there.
Also, you need to think about your likes and dislikes and then research the various states. You like sunshine
and hate snow? Then you probably won"t like the Midwest or even the Northeast. Open space, nature and
peace and quiet? Then you probably should stay away from America"s large cities. Are you interested in
government? Then Washington D.C. is the only place for you. Whatever you decide, put some thought into it.
The place you live could be the difference between a great study-abroad experience and a state of great
suffering on earth.
B. all colleges and universities lie in beautiful places
C. famous colleges and universities lie in nice places
D. famous colleges and universities may not lie in nice places
B. The scenery.
C. The study condition.
D. The living condition.
B. California is the worst place to live in
C. California is a state with different climates
D. California is a small state in the USA
B. feel the real character of the nation
C. meet the most famous professors there
D. face more difficulties
B. Washington is the political centre of the USA
C. you can"t find sunshine in the Midwest
D. you can"t find any universities out of big cities in the USA
understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly
with confidence (自信) and without hesitation (犹豫). Thirdly, we must be able to write it. We must be able
to make sentences that are correct in grammar.
There is no short way to succeed in language learning. A good memory is a great help, but it is not enough
only to memorize the rules from a grammar book. It is no much use learning by heart long lists of words and
their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with
a few rules we have memorized, we are not really learning the language. We must "Learn through use". Practice
is important. We must practise speaking and writing the language whenever we can.
B. hearing, speaking, reading and writing
C. writing and understanding
D. memorizing and listening
B. Speaking.
C. Practice.
D. Writing.
B. we learn foreign language in order to use it
C. we can learn a language well while we are using it
D. both B and C
new study of hamsters.
Tracy Bedrosian, a researcher at Ohio State University, US, presented the research on November 17 at
the annual meeting of the American Society for Neuroscience (神经系统科学) in San Diego.
Researchers believe that even having a dim (暗淡的) light on-such as a night light often used in a child"s
room or the glow (发光) of a TV screen, changes the chemical balance of the brain.
While more work is needed to find out if the results are relevant to human beings, the findings might
explain why night-shift (夜班的) workers are at higher risk of depression than others, the researchers said.?
Over the last century, nighttime lights have become common, but it"s not clear whether sleeping with one
has an effect on the brain.
As part of the investigation, Tracy Bedrosian, a researcher at Ohio State University, and her team, placed
hamsters in two environments. In one, hamsters experienced 16 hours of daylight and eight hours of complete
darkness each day. In the other, the animals experienced 16 hours of daylight, but at nighttime, a dim light was
kept on.
After eight weeks, the researchers tested the hamsters for behaviors that would suggest they were
depressed. For example, they looked to see whether the hamsters still practiced activities they usually enjoyed,
such as drinking sugar water.
In people, loss of enjoyment is known as a symptom of depression.
Hamsters in both groups were given a choice between drinking tap (水龙头) water or sugar water. The
hamsters that slept with lights on at night drank similar amounts of tap and sugar water - they"d lost their
preference (偏好) for the sweet water.
"That suggests to us that they are not getting the same pleasure from drinking their sugar water, and that
may be a depression-like response," Bedrosian said.
Researchers found these changes in behavior were caused by chemical changes in a part of brain called
the hippocampus (海马状突起).
Previous studies on humans have found the hippocampus to be involved in depression. A patient with major
depression has a smaller hippocampus, Bedrosian said.
If the same mechanism (机制) exists in people, then they "might want to try to avoid falling asleep with
their TVs on all night," Bedrosian said.
B. To sleep with the light on.
C. To sleep in a new environment.
D. To sleep after drinking sugar water.
B. Sleeping with the light on affects the human brain.
C. Two groups of hamsters drank similar amounts of sugar water.
D. Hamsters no longer enjoyed drinking sugar water after they had slept with the light on.
B. A depressed patient has a larger hippocampus.
C. People who stay up late at night are more likely to be depressed.
D. The hamsters" behavioral changes were caused by chemical changes in the brain.
B. not to watch TV at night
C. to sleep in total darkness
D. to put an end to night shifts
but 2 is very useful, especially when we travel to other countries. If we go to France, we ought to be able
to speak 3 , and in Germany people will 4 us to understand German.
How many languages are there in the world? There are about fifteen hundred, but many of them are not
very 5 . English is one of the most important languages 6 so many people use it, not only in England and
the USA, 7 in other parts of the world. More than 200,000,000 speak it 8 their own language, and about
another 200,000,000 use it as a second language. It is 9 to say how many people are learning it. Many
millions of school boys and school girls are trying to do so.
English children study French, which is also a very 10 language. An Englishman can 11 find someone
in almost all parts of the world who is able to talk to him in either English or 12 .
Which is the best way to learn a language? We should remember that we all learnt our own language well
when we were children. If we could learn a second language in the same way, it would not seem so 13 .
Think of what a child 14 . It listens to what people say, and it tries to imitate (模仿) what it hears. When it
wants something, it 15 ask for it. It is 16 the language, talking in it, and thinking in it all the time. If people
had to use a second language all the time, they would learn it quickly.
17 is also important to remember that we learn our own language by hearing people speak it, not by
seeing 18 they write. We imitate (模仿) what we hear. In school, 19 you learn to read and write as well
as to hear and speak, it is 20 to learn all the new words first through the ear. You can read them, spell them,
and write them later.

In order to know a foreign language thoroughly (完全地), four things are necessary. First, we must understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, with confidence (自信) and without hesitation (犹豫). Thirdly, we must do much reading. Finally, we must be able to write it. We must be able to make sentences that are correct in grammar. There are no shortcuts to success in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. It is not much learning by heart long lists of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must "learn through use." Practice is important.
