you see both the letters. Then close your right eye and look at the letter R only
with your left eye. And now, as you move the card slowly towards you, you"ll
find the letter L disappearing. But if you move the card nearer to your face, the
letter will be seen again. Now do the same experiment with your left eye closed,
you"ll find the letter R disappearing.

阅读理解 People who talk and sing to plants are not crazy, according to Mr. Braymar, an agriculture expert(农业专家). "In
fact, singing and talking to plants makes them grow better," says Braymar. The reason is quite simple -- when we
sing or talk to plants, we breathe out carbon dioxide (二氧化碳) which plants need to live and grow. Plants take in
the carbon dioxide during the sunlight hours and produce oxygen(氧气) which people need to live. Singing and
talking is effective, however, only during the daytime.1. Plants need ________ in the daytime.A. carbon
B. dioxide
C. carbon dioxide
D. oxygen2. Carbon dioxide helps plants ________.A. to take in oxygen
B. to sleep well
C. to drink water
D. to live and grow better3. The point of the paragraph is that singing and talking to plants can be ________.A. good for the people who do so
B. helpful to both people and plants
C. dangerous to people D. polluting the air

阅读理解。
     What is your favorite color? Do you like yellow, orange and red? If you do, you must be an optimistic
(乐观的), a leader, an active person who enjoys life, people and excitement. Do you prefer grey and
blue? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a
pessimist (悲观主义者). At least, this is what psychologists (心理学家)tell us, and they should know,
because they have been seriously studying the meaning of color preference (喜好) as well as the effect
that colors have on human beings. They tell us, among those facts, that we don"t choose our favorite
color as we grow up - we are born with our preference. If you happen to love brown, you did so, as
soon as you opened your eyes, or at least as soon as you could see clearly.
     Colors do influence our moods. There is no doubt about it. A yellow room makes most people more
cheerful and more relaxed than a dark green one. And a red dress brings warmth and cheer to the
saddest winter day. On the other hand, black is depressing. A black bridge over the Thames River near
London, used to be the scene of more suicides (自***) than any other bridge in the area - until it was
repainted green.
     Light and bright colors make people not only happier but more active. It is a fact that factory workers
work better, harder, and have fewer accidents when their machines are painted orange rather than black
or grey.
1. If you enjoy life, one is sure to prefer _____.
    A. red to yellow
    B. blue to orange
    C. red to grey
    D. blue to yellow
2. Those who tend to be pessimists preferred the bridge over the Thames River near London to others
because of _____.
    A. its shape
    B. its structure
    C. its color
    D. its building materials
3. Which of the following is TRUE?
    A. People"s preference of one color to another is instinct.
    B. People"s preference of one color to another is learned as we grow up.
    C. More people love brown because they saw brown when they were born.
    D. Colors have little influence on our moods.
4. If the bridge over the Thames River near London is painted in pink, perhaps the number of suicides
   will _____.
    A. rise a lot
    B. fall quite a lot
    C. be the same as before
    D. become larger

阅读理解。   Have you ever dreamed about a trip to space? Seeds (种子)of some vegetables and crops are a lot
luckier than you, as they have travelled to space and back.
    China is among the three countries in the world that carry out agricultural (农业的)research in space.
The others are Russia and the U.S. Since 1987, China has sent about 1000 kinds of seeds into space.
These include green peppers, tomatoes, cucumbers, carrots and rice. Even on China"s first manned spacecraft Shenzhou V there were some seeds from Taiwan.
    "Conditions(条件) in outer space such as radiation(辐射)and low gravity can cause big changes in the
seeds," said Chinese researcher Jin Xing.
    But not all seeds are better after going to space. After returning to the earth, the best seeds are chosen. These seeds produce much more and also grow faster than normal seeds. As the safety of genetically
modified(转基因)food is still being talked about, some people are not sure about the safety of these
"space vegetables" because some of their genes(基因)are changed during the trip to space.
   But Jin holds the more hopeful view. He said, "Unlike genetically modified crops, no new genes are
introduced to the space vegetables, so they are surely safe."
    Space vegetables are better than normal vegetables. For example, space tomatoes stay fresh for twenty
days, which is one week longer than normal tomatoes. Another popular space vegetable is the peppers.
Space peppers have 20 per cent more vitamin C than normal peppers.
    Researchers are considering holding a tomato festival. By the time people will be able to enjoy about 30 different kinds of space tomatoes on their dining tables.
So far, the Chinese Academy of Sciences has set up three space vegetable base fields, one of which is in
Shenzhen while the others are in Beijing and Jiangsu Province.
1. What will happen when seeds of some vegetables are sent to space and carried back?A. Some of their genes are changed.
B. They are all better than before going to space
C. No changes are caused in the seeds.
D. They all produce much more and grow faster.2. Why does Jin Xing have no doubt about the safety of the space vegetables?A. Because the seeds sent to space stay the same.
B. Because the seeds sent to space are the best.
C. Because no new genes are brought into them.
D. Because space vegetables are luckier. 3. Which of the following statements is TRUE?A. Genetically modified food is completely safe.
B. The space vegetables don"t belong to genetically modified food in some ways.
C. About 1000 kinds of seeds were sent into space on Shenzhou V.
D. Seeds back from space must be planted in special rooms controlled by computers. 4. What is the underlined word "cucumber" in the second paragraph? A. A product from Russia.
B. A kind of gene. .
C. A product from Taiwan.
D. A kind of agricultural product.

we do not get enough fresh air we wake up feeling tired. While in bed we must not cover our heads. If we do, our lungs
(肺) will not get enough fresh air. If we open our windows at night we can have plenty of fresh air. Cool air is better than

阅读理解。     Rivers are one of our most important natural resources (自然资源). Many of the world"s great cities
are located on rivers, and almost every country has at least one river flowing through it that plays an
important part in the lives of its people.
     Since the beginning of history, people have used rivers for transportation. The longest one in the
United States is the Mississipi. The lifeline of Egypt is Nile. To the people of India, the Ganges is great,
but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers
are the Congo in Africa and the Mekong in Southeast Asia. The greatest of all for navigation (航海),
however, is the Amazon in Brazil (巴西). It is so wide and so deep that large ships can go about two
thousand miles upon it.
     Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun
and recreation for the people who live along their banks. In order to increase the supply of water for
crops, engineers sometimes build a dam (大坝) across a river and let a lake form behind the dam. Then
people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes
and industries. However, large cities and industries that are located upon rivers often make problems. As
the cities grow in size and industries increase in number, the water in the rivers becomes polluted
with chemicals and other materials. {people are learning the importance, however, of doing more to keep
their rivers clean if they want to enjoy the benefits (利益) of this natural resource.

A. people"s drinking water too much
B. people"s swimming in the river too much
