（B）
What does an astronaut eat in space? This is a question that will puzzle many, as people rarely think of that. In the early space-travel years, astronauts ate dehydrated (脱水的) foods that were eaten through straws （吸管）. In today’s space-age, the food that they eat is totally different. They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety of foods in space. Some can be eaten in their natural form, like fruits, while some need to add water, like noodles. However, there are no refrigerators, so the food has to be prepared and eaten without being stored for a long time. When the astronauts are hungry, they simply eat the food by opening the food packages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which include breakfast, lunch and dinner. Sometimes they also eat snacks. The US space agency NASA has found out that an astronaut’s diet reduces by about 70% on a space mission, though he has a wide range of foods to choose from like nuts, chicken, beef, seafood, and candies. Drinks in the spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space foods that can be offered to astronauts when on space missions.
45. Now astronauts eat ________ in space.
A. dehydrated (脱水的) foods           B. food as people do on Earth
C. totally different                    D. food with a lot of water
46. The food the astronauts prepared ________ .
A. can’t be stored for a long time       B. can be put into refrigerators
C. can be stored for a long time          D. can’t be kept in the food packages
47. In space, astronauts ________ like people on Earth.
A. only have nuts, chicken and beef       B. onlyhave lunch for a day
C. only drink coffee, tea and lemonade    D. also eat three meals a day
48. What are scientists experimenting and trying out?
A. Some very special snacks.             B. How astronauts can sleep well.
C. Different space foods for astronauts.     D. How to get some fruits for astronauts.

四、阅读理解（本题有16小题，每小题2分，共32分）
第一节：阅读下列短文，从每题所给的A、B、C、D四个选项中，选出一个最佳答案。
It’s important to learn about protecting our environment. Here is a 5R rule for us:
1. Reduce
If you want to reduce waste, you should use things wisely. A large number of trees are being cut down to make paper. If everyone uses paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste.
2. Reuse
You should always think of reusing the usable things before throwing them out. Give your used clothes or the small ones to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat (压平) and melted (融化) and the metal things are made for new coke cans.
4. Recover
When you buy a box of apples, there may be few rotten apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
51. The “Reduce” rule mainly requires us _______.
A. to use things wisely                          B. to cut down many trees
C. to use a lot of paper                          D. to throw away your old clothes
52. What’s the right order of recycling coke cans?
a. collect the used cans                              b. melt them
c. smash them flat                                     d. send them to a factory
A. a b c d                    B. a d c b                     C. d b c a                     D. c a b d
53. The “Recover” rule mainly requires us _______.
A. to throw waste things away                          B. to cover waste things with earth
C. to get back the useful parts                           D. to throw the whole things away
54. Which is the best way to do with your broken tables?
A. Throwing them away.                                  B. Repairing them.
C. Selling them.                                              D. Putting them away.

An important factor that plays a part in susceptibility （易受影响） to colds is age．A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population．Babies are the group suffering most from colds, averaging more than six colds in their first years．Boys have more colds than girls up to age three．After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two．
The general frequency of colds continues to decline into adults．Elderly people who are in good health have as few as one or two colds annually．One exception is found among people in their twenties, especially women, who show a rise in cold infections（感染）, because people to this age group are most likely to have young children．Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections．
The study also found that economics （经济状况） plays an important role．As income increases, the frequency at which colds are reported in the family decreases．Families with the lowest income suffer about a third more colds than families at the upper end．Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person．Low income may also influence diet．The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally．
68. What factors cause people to catch colds easily?
A. Age and pregnancy． B. Health and pregnancy．
C. Health and economics． D. Age and economics．
69. Why does the lowest income lead to the rapid spread of colds?
A. Because poor people can't afford to go to see a doctor．
B. Because balanced diet has definitely affected poor people．
C. Because people with the lowest income have limited living space．
D. Because cold virus don't have opportunities to travel in poor families．
70. How does the study prove that age plays a part in susceptibility to colds?
A. Using comparison． B. Using graphs．
C. Using description． D. Using argument．
71. What can you learn from the passage?
A. Families with the lowest income suffer less colds than rich families．
B. The general frequency of colds are likely to increase among the poor．
C. Women in their twenties are most likely to avoid cold infections．
D. The general frequency of colds continue to rise into the adults．

E
Computer mouse is no longer so strong. A Canadian engineer has invented a system that enables a computer user to push a cursor（光标）across a screen simply by moving his or her nose .He calls his nose-driven mouse a mouse.
The inventor ,Dmity Gorodnichy ,came up with the idea for the mouse while building computer software that would help astronauts operate the Canadarm—a long robotic arm on the U.S. space shuttle .His system employs a web-camera that recognizes a computer user’s nose from 25 pixels ,or points of light. Dmity chose the nose because its position remains relatively constant no matter which way the head moves .The system keeps track of the pixels, and the user matches the movements of his or her nose with the progress of the cursor across the screen.
The mouse keeps track of the eyes too. Two blinks（眨眼）are a “double click,” which turns the mouse on or off.
The mouse has received mixed comments from those who hold opposite opinions. One called it “a pointless waste of technology” . Another predicted that the nouse will fail to catch on because it makes users “look silly.” Dmity has already adapted the nouse for NousePong, a video game ,and NousePaint ,a drawing program.
He also predicts that the mouse will attract the people who have suffered from specific disease-pain ,senselessness ,or trembling in the hand caused by the frequent repetition of movements of the wrist and fingers ,such as typing at a computer keyboard .His next plan is to adapt the nouse for use by paralyzed（瘫痪）patients in hospitals .With two blinks of the eyes ,patients could double-click for help.
72．The best title for this passage is probably      .
A．Mouse Driven by Nose
B．Cursor Moved Without fingers
C.New Computer System for Astronauts
D．New Type of Mouse for Patients
73．The nouse is a system working by means of          .
A．keeping track of the points of light
B．moving one’s nose or blinking
C.moving cursor across the screen
D．matching the user’s nose with eyes
74．The underlined phrase “catch on” means “       ”.
A．become popular     B．be used      C.get improved        D．be made
75．Dmity predicts that the nouse will be more used to help          .
A．those who have eye trouble
B．develop a video game and drawing program
C.those traveling in space
D．the disabled with the hand and paralyzed patients

D
As they migrate（迁移），butterflies and moths choose the winds they want to fly with，and they change their body positions if they start floating in the wrong direction．This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances．Scientists have long thought that insects were simply at the mercy of the wind．
Fascinating as their skills of flight are，migrating behavior has been difficult to study in insects because many long distant trips happthousands of feet above ground．Only recently have scientists developed technologies that can detect such little creatures at such great heights．
To their surprise，though，the insects weren’t passive travelers on the winds．In autumn，for example，most light winds blew from the east，but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes．
Even in the spring，when most winds flowed northward，the insects didn’t always go with the flow．If breezes weren’t blowing in the exact direction they wanted to go，the insects changed their body positions to compensate．Many migrating birds do the same thing．
The study also found，butterflies and moths actively flew within the air streams that pushed them along．By adding flight speeds to wind speeds，the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour．The findings may have real-world applications．With climate warming，migrating insects are growing in number．Knowing how and when these pests move could help when farmers decide when to spray their crops．
71．What’s the main idea of the text?
A．Insects migrate with the seasons．     B．Wind helps insects greatly in migrating．
C．Windsurfing insects have real direction．D．Scientists have trouble in observing insects．
72．Scientists originally thought that____________．
A．insects always waited for their favourable winds
B．insects chose the winds they wanted to ride
C．insects were just blown about by the wind
D．insects positioned themselves in the winds
73．It is not easy to stuay the migrating behavior of the insects because____________
A．the little creatures can fly very fast     B．they have no regular migrating courses
C．the wind’s direction is hard to foresee    D．their flight is long and high above ground
74．We can learn from the text that______________.
A．insects fly in the way birds do
B．insects travel more easily in autumn
C．insects never position themselves when flying low
D．insects rest a lot when the wind pushes them along
75．According to the passage，the findings can              ．
A．increase insects in number         B．instruct farmers when to spray
C．prevent climate warming       D．help protect insects

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration （集中）of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution.
Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a “greenhouse effect” - raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is preventing sunlight and lowering the earth’s temperature - a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen though one recent government reports that the greenhouse effect is very possible. Perhaps, if we are lucky enough, the two tendencies will offset（抵消）each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people don’t think about the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worth?
72. As pointed out at the beginning of the passage, people used to think that air pollution ________.
A. caused widespread damage in the countryside
B. affected the entire eastern half of the United States
C. had damaged effect on health
D. existed only in urban and industrial areas
73. As to the greenhouse effect, the author ________.
A. shares the same view with the scientists
B. is uncertain of its happening
C. rejects it as being ungrounded
D. thinks it will destroy the world soon
74. It can be concluded from the last paragraph that ________.
A. lowering the world’s temperature only a few degrees would lead major farming areas to disaster
B. raising the world’s temperature only a few degrees would not do much harm to life on earth
C. almost no temperature variations have occurred over the past decade
D. the world’s temperature will remain constant in the years to come
75. This passage is mainly about ________.
A. the greenhouse effect
B. the burning of coal and oil
C. the potential effect of air pollution
D. the likelihood of a new ice age

Be careful what you say around your dog. It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!
72. From paragraph 2 we know that _______.
A. animals are as clever as human beings
B. dogs are smarter than parrots and chimpanzees
C. chimpanzees have good word-learning skills
D. dogs have similar learning abilities as 3-year-old children
73. Both experiments show that_________.
A. Rico is smart enough to get all commands right
B. Rico can recognize different things including toys
C. Rico has developed the ability of learning mathematics
D. Rico won't forget the names of objects once recognizing them
74. Which of the following statements is true?
A. The purpose of the experiments is to show the border collie's mental abilities.
B. Rico has a better memory partly because of its proper early training.
C. The border collie is world-famous for recognizing objects.
D. Rico is born to understand its owner's commands.
75. What does the writer want to tell us in the last paragraph?
A. To train your dog.          B. To talk to your dog.
C. To be friendly to your dog.   D. To be careful with your dog.

Children who speak English as their first language are now a minority in inner-city London primary schools，official figures show.
Youngsters with foreign mother tongues form a majority at primary schools in 13 out of33 London cities. Across the country，English is a foreign language to more than one in seven primary school youngsters.
The figures from the Department for Children，Schools and Families (DCSF) point to major demographic (人口的) changes over the past few decades，with around a fifth of pupils now coming from ethnic minorities.
There are concerns that school finances are coming under stress from the growing numbers of youngsters requiring help with English. The government has been urged to provide more funding，and give fair treatment to schools with large concentrations of non-English speakers.
In Tower Hamlets almost four out of five youngsters do not have English as their mother tongue. In other areas，including Leicester，Luton and Bradford the proportion approaches 50 percent.
The figures indicate that many recent migrants have settled in London. Sir Andrew Green，Founder and Chairman of Migration Watch UK，says，“These figures confirm the huge impact immigration is having on our society. When government funds are as tight as they are，this is bound to have a negative impact，since children for whom English is a second language need extra tuition (学费).”He adds，“In inner London it's hard to know with whom immigrant children are supposed to practice English，since the number of immigrant children is much larger than that of local. ”
A spokesman for DCSF stresses that the figures “only indicate the language to which a child was initially exposed at home，regardless of whether he or she comes to speak English fluently later on. It is only a relatively few recent arrivals for whom communication problems are serious”.“We are increasing funding to the Ethnic Minority Achievement Grant (助学金)to £206 million by 2010，to help bring students weak in English up to speed. We’re also equipping schools to offer effective English as an Additional Language teaching to new arrivals，”he adds
72.A minority of London primary school students speak English as their first language because
      .
A. local children prefer to speak other languages
B. more and more immigrant children are attending school in London
C. children learning English as an additional language need extra tuition
D. English is too difficult a language for primary school children to learn
73.Some people worry about      .
A. the increasing number of adults needing help with English
B. the government taking no measures to help the schools
C. non-English speakers putting school finances under stress
D. London schools not providing adequate service for children in need
74.It can be inferred from the passage that         .
A. most immigrant children make a great effort to learn English
B. the government used to treat non-English speakers unfairly
C. it's not easy to find English speakers for immigrant children in some parts of London to communicate with
D. local children are influenced by immigrant children
75.According to the spokesman for DCSF，the figures indicate       .
A. that children will speak English fluently later on
B. that immigration is having a huge impact on English society
C. what the language the children were exposed to first was
D. that funding is increasing to help students weak in English
