use to communicate with each other. Karl von Frisch, a professor from Austria, devoted many years of his life
to researching the ways honey-bees communicate in their hives (蜂房). Karl von Frisch built special hives, a
glass wall and painted some honey-bees with different colors.
A marked bee which returned to the hive from the feeding table performed a dance on the surface of the
honeycomb (蜂巢). First it made a circle to the right, then to the left. It repeated these circles again and again.
The surrounding bees copied its dances and then they left for the feeding place.
Karl von Frisch set up two feeding places. One was close to the hive the other was farther away. The bees
that had been at the nearby feeding place were doing the circling dance. The bees at the distant feeding place
were dancing differently. The dancer ran in a straight line, wagging (摇摆) from side to side. Then it turned in
a semicircle (半圆), ran straight again, and turned in another semicircle to the opposite side. It repeated the
dance over and over. The dances convey messages about the far-away feeding place. Karl von Frisch and his
assistants slowly moved a feeding place close to the hive farther and farther away and they counted how many
times the bees repeated the dance in one minute. Finally they found out the number of wagging dances per
minute told the exact distance to the feeding place.
B. The honey-bees enjoy a strange way of communication.
C. The honeydew is delicious.
D. there are several kinds of bees in the world.
B. Australia
C. Sweden
D. Austria

necessary so, however. Anyone can become a better student if he or she wants to. Here"s how:
1. Plan your time carefully. When you plan your week, you should make a list of things that you
have to do. After making this list, you should make a schedule of your time. First your time for eating,
sleeping, dressing, etc. then decide a good, regular time for studying. Don"t forget to set aside enough
time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize
what is happening to your time.
2. Find a good place to study. Look around the house for a good study area. Keep this space, which
may be a desk or simply a corner of your room, free of everything but study materials. No games, radios,
or television! When you sit down to study, concentrate on the subject.
3. Make good use of your time in class. Take advantage of class time to listen to everything the
teachers say. Really listening in class means less work later. Taking notes will help you remember what
the teacher says.
4. Study regularly. When you get home from school, go over your notes. Review the important points
that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read
that material will become more meaningful, and you will remember it longer.
5. Develop a good attitude about tests. The purpose of a test is to show what you have learned about
a subject. They help you remember your new knowledge. The world won"t end if you don"t pass a test, so
don"t be overly worried.
There are other methods that might help you with your studying. You will probably discover many others
after you have tried these.
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
