阅读理解。     Sleeping in anything other than a completely dark room could cause depression (抑郁), according to a
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. 1. What may cause depression according to the article? [     ]
A. To sleep in the dark.
B. To sleep with the light on.
C. To sleep in a new environment.
D. To sleep after drinking sugar water. 2. What did Tracy Bedrosian and her team find in the research? [     ]
A. Loss of enjoyment is a symptom of depression.
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. 3. Which of the following statements is TRUE according to the article?[     ]
A. TV noise may affect quality of sleep.
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. 4. If the research turns out to be useful for understanding of human depression, it would be advisable _____. [     ]
A. to sleep with a night light
B. not to watch TV at night
C. to sleep in total darkness
D. to put an end to night shifts

完形填空。     In schools all over the world boys and girls are learning foreign languages.   1   knows his own language,
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. We must practise speaking and writing the language whenever we
can.
1. The most important things to learn a foreign language are _____.
[     ]
A. understanding and speaking

     When we hear the words "college student", we usually think of a young person between 18 and 22 years
old. But in the USA today, a college student often is much older. In fact, educators say in the next few years
colleges and universities may have more older part-time students than traditional full-time younger students.
     Educators report a big increase in the number of Americans who attend college and university classes in
the evening or at night or weekends. Most of them are older than 25 years old and more have full-time or part-
time jobs. Many are in their thirties or forties.
     Why are so many people deciding to spend their time and money in order to continue their education? Most
are doing it because they believe more education will help them to get a better job. Some are industrial workers
whose factories have closed. They are learning new skills to prepare for other kinds of work. Some of the part-
time students are not pleased with the jobs they have. They are studying for new ones. Some have retired (退休)
and are looking for new kinds of jobs. Two of every three of the students older than 35 are women. Many of
them are returning to school after years of staying at home to care for children.
     Are older students good students? Most teachers say yes. They say older students really want to learn. They
ask difficult questions and are not pleased with simple answers. They often get high grades.

     Many American schools have a student exchange program with foreign countries. Along with this
program, there is usually another one called the "American Host Family" program. As its name suggests,
the program gets American families involved in foreign students" lives in America and offers homes for
them.
     Foreign students generally welcome such an opportunity to have a"family" here, but there are also
those who prefer to stay "homeless".
     Many American families volunteer to host foreign students. However, if there is a shortage of host
families, schools also get in touch with local people and introduced foreign students to them.
     The "American Host Family "program changes in lengths of time. It can go from a few days to a few
years, depending on each individual school. After the first year is over, it is up to foreign students and
their "families" to decide if they want to stay together as a "family". American families can host as many
foreign students as they like. They can either have several students or just one at a time. Many families
start with new students each year while still keeping in touch with the old ones. Schools usually leave it
to foreign students and their host families to decide their activities after both sides meet.
     My school, however, holds activities every year. On major holidays like Easter, Thanksgiving and
Christmas, foreign students are usually invited to their themes for dinner. Even schools that do not have
host family programs often arrange students to get together with American families on these special holiday
occasions.
     It is typical that a host family invites its foreign daughter or son over, and they cook the student"s home
food together, Undoubtedly, Chinese students are usually considered good cooks, whether or not they are
really qualified for such praise at home. Although many Chinese students rarely cooked at home, they often
have a hard time making their American friends believe that they cannot cook. It often happens when a
Chinese student promises to cook a Chinese meal for his host family, he usually sees a little crowd expecting
him: friends or relatives are also invited over for the "special" Chinese food!
1. The best title of the passage might be _____.
[     ]
A. Studying in the U.S.
B. The "Host Family Program"in the U.S.
C. The "Student Exchange Program" in the U.S.
D. Activities in American Schools
2. What"s the purpose of the "American Host Family program"?
[     ]
A. To bring foreign students closer to American life.
B. To provide homes for foreign students.
C. To make greater progress in the study of foreign students.
D. To supply "sons" or "daughters" for American families.
3. What can we know about the program from the fourth and fifth paragraphs?
[     ]
A. Its time,the number of students and families.
B. Its activities,the number of schools and students.
C. Its lengths of time,the number of students and activities.
D. The number of students,the lengths of time and important holidays.
4. We can know from the last paragraph that _____.
[     ]
A. foreign students must prepare their home food for their host family
B. not all Chinese students are good cooks in the eyes of Americans
C. it is good manners to invite relatives or friends to taste foreign food
D. Americans are very interested in foreign food

     Language learning begins with listening. Children are greatly different in the amount of listening they do
before they start speaking, and later starters are often long listeners. Most children will "obey" spoken
instructions some time before they can speak, though the word "obey" is hardly accurate as a description of
the eager and delighted cooperation usually shown by the child. Before they can speak, many children will
also ask questions by gesture and by making questioning noises.
     Any attempt to study the development from the noises babies make to their first spoken words leads to
considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one
or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since
these can"t be said to show the baby"s intention to communicate, they can hardly be regarded as early forms
of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by
six months they are able to add new words to their store. This selfimitation (模仿) leads on to deliberate (有意
的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point
at which one can say that these imitations can be considered as speech.
     It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person
means by it in a particular situation and it is clear that what a child means by a word will change as he gains
more experience of the world. Thus the use at seven months of "mama" as a greeting for his mother cannot be
dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or
anything else he likes. Playful and meaningless imitation of what other people say continues after the child has
begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this
ability in an attempt to teach new sounds.
1. Before children start speaking _____.
[     ]
A. they need equal amount of listening
B. they need different amounts of listening
C. they are all eager to cooperate with the adults by obeying spoken instructions
D. they can"t understand and obey the adult"s oral instructions
2. Children who start speaking late _____.
[     ]
A. may have problems with their listening
B. probably do not hear enough language spoken around them
C. usually pay close attention to what they hear
D. often take a long time in learning to listen properly
3. The problem of deciding at what point a baby"s imitations can be considered as speech _____.
[     ]
A. is important because words have different meanings for different people
B. is not especially important because the changeover takes place gradually
C. is one that should be properly understood because the meaning of words changes with age
D. is one that should be completely ignored (忽略) because children"s use of words is often meaningless
4. The speaker wants to tell us that _____.
[     ]
A. parents can never hope to teach their children new sounds
B. children no longer imitate people after they begin to speak
C. even after they have learnt to speak,children still enjoy imitating
D. children who are good at imitating learn new words more quickly
