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.

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.
1. Which of the following is WRONG according to the passage?
A. The Mile is in India.
B. Almost every country has at least one important river.
C. Many cities are located on rivers.
D. Rivers play an important part in the lives of people.

C. washing clothes
D. irrigating and making electricity
3. The water in the river is polluted because of                          .
A. people"s drinking water too much
B. people"s swimming in the river too much
C. chemicals and other materials
D. people"s building a dam across a river
4. The best title of the passage is                        .

阅读理解。     It is common to believe that learning just takes place in school, but much of human learning happens
outside the classroom, even from birth and people continue to learn throughout their lives.
     Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in
their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn subjects like reading, writing, and maths. They also continue to learn a lot outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other
children. After they finish school, people must learn to deal with many changes that affect their lives, such
as getting married, raising children, and finding and keeping a job.
     Because learning continues throughout our lives and affects almost everything we do, the study of
learning is important in many different fields. Teachers need to understand the best ways to educate
children. Scientists, social workers and other human service workers need to understand how certain
experiences change people"s behaviors.
     Learning is closely related (相关的) to memory, which is the storage of information in the brain (大脑). Scientists who study memory are interested in how the brain stores knowledge, where this storage takes
place, and how the brain later offers knowledge when we need it. However, scientists who study learning
are more interested in behavior and how behavior changes as a result of a person"s experiences. ?1. The underlined word "siblings" in Paragraph 2 probably means _________.A. teachers
B. classmates
C. doctors
D. brothers or sisters2. When do children begin to know to behave well according to the passage?A. After they go into society.
B. Before they enter school.
C. When they are at school.
D. Before they are born.3. Which of the following is WRONG according to the passage?A. As a matter of fact, learning begins at a person"s birth and last the whole life.
B. Teachers need to understand the best ways to educate their students.
C. People need to understand how certain experiences change their behaviors.
D. Social workers need to study how experiences affect people"s thoughts.

阅读理解。     Once a baby cries, the parents will go to see what happened as soon as possible. According to a new study, a baby"s cry can make adults react(反应) very quickly, even if they are not related.
     Oxford University researchers used the classic game whack-a-mole for the study.  Whack-a-mole(打鼹鼠游戏) requires people to hit one of nine buttons (按钮). The players must react as quickly as they
can to whichever of the buttons lights up at random(随机). It is a game that requires speed and accuracy (准确度 ).
    The study included 40 men and women volunteers aged 19 to 59. Some of them had sons or daughters but none had a baby at the time. They played whack-a-mole after listening to different sounds, including
babies crying, the crying of adults in trouble and birdsong played at a similar pitch to the babies" cries.
    The volunteers" scores were higher after listening to the sound of crying babies. Men and women had
similar scores overall. The results showed that a crying baby gets special attention.
    "Few sounds make people react quite like the cry of a baby," said Morten Kringelbach of Oxford"s
psychiatry(精神病学) department, who led the study. "For example, it"s almost impossible to ignore(忽视,不理) crying babies on planes. This is true even though there are so many other noises around."
     He added that a baby"s cry can increase adults" heart rate and blood pressure. This is understandable,
because in the course of human evolution (进化), taking care of babies has always been an important job
for adults. When a baby is hungry or feeling bored or unwell, it will cry. As a result, human brains and
bodies develop a special reaction to a baby"s cry.  1.According to the passage, which of the following statements is TRUE?A. There were 80 volunteers who took part in the study.
B. The youngest volunteer was 19 and the oldest was 59.
C. Some volunteers had babies at that time in the study.
D. The volunteers were affected by the sound of a baby"s cry.2. The game "whack-a-mole" shows ______.A. a baby"s cry can get special attention from adults
B. men and women have different reaction speed and accuracy
C. adults without babies react less quickly to a baby"s cry
D. women react to a baby"s cry more quickly than men3. "Whack-a-mole" requires people to hit _____ at a time.A. one button
B. one of nine buttons
C. nine buttons
D. ten buttons 4. According to the passage, a baby"s cry ______.A. has the same pitch as birdsong
B. is the noisiest sound there is
C. can increase adults" heart rate and blood pressure
D. is good for its health5. From the last paragraph, we learn that ______.A. taking care of the younger babies was the most important thing in the past
B. human brains and bodies have developed to take care of babies
C. baby cries are a good way make adults react quickly
D. baby cries have developed a lot during the course of human evolution
