阅读理解     Millions of people around the world cook their food over a smoky fire every day.It is often difficult to
find wood for the fire.People who do not have wood must spend large amounts of money on cooking fuel.
However,there is a much easier way to cook food using energy from the sun.
     Solar cookers,or ovens,have been used for centuries.A Swiss scientist made the first solar oven in
1767.Today,people are using solar cookers in many countries around the world.People use solar ovens to
cook food and to heat drinking water to kill bacteria and other harmful organisms.
     There are three kinds of solar ovens.The first is a box cooker.It is designed with a special wall that
shines or reflects sunlight into the box.Heat gets trapped under a piece of glass or plastic covering the top
of the cooker.A box oven is effective for slow cooking of large amounts of food.
     The second kind of solar oven is a panel cooker.It includes several flat walls,or panels,that directly
reflect the sun"s light onto the food.The food is inside a separate container of plastic or glass that traps heat
energy.People can build panel cookers with very few supplies quickly.They do not cost much.In Kenya,for
example,panel cookers are being manufactured for just two dollars.
     The third kind of solar oven is a parabolic(抛物线的) cooker.It has rounded walls that aim sunlight
directly into the bottom of the oven.Food cooks quickly in parabolic ovens.However,these cookers are
hard to make.They must be reaimed often to follow the sun.Parabolic cookers can also cause burns and
eye injuries if they are not used correctly.
     You can make solar ovens from boxes or heavy paper.They will not catch fire.Paper burns at two
hundred thirtytwo degrees Celsius.A solar cooker never gets that hot.Solar ovens cook food at low
emperatures over long periods of time.This permits people to leave food to cook while they do other
things.1．Which of the following should be the best title for this text?A. Cooking food with solar energy
B. How to make solar cookers
C. Introduce a new kind of energy
D. Different kinds of cookers2．From this passage we know that ________.A. there is no wood for people to use while making a fire now
B. people have been using solar cookers for more than 200 years
C. solar energy is the cleanest energy on the earth
D. more and more people cook food on smoky fires3．Parabolic cookers may be dangerous to us because ________.A. they may direct electricity to us humans
B. they may explode easily
C. they may cause burns and eye injuries
D. they may cause fires4．The third,fourth and fifth paragraphs mainly ________.A. show how to make solar cookers
B. explain which is the best cooker
C. prove that solar cookers need improving
D. tell us the different making ups of the three kinds of solar cookers

We often think of future. We often wonder what the world will be like in a hundred years" time. Think of space, perhaps a permanent (永久的) station on the moon will have been set up. Perhaps people will be able to visit the moon as tourists. Cheap rockets for space travel will have been developed, permitting long journeys throughout the solar system(太阳系). When that time comes, people will be taking holidays in space and visiting other planets. Creat progress will have been made in medicine, too. Perhaps a cure will have been discovered for the most terrible of all diseases-cancer. Pollution is a problem we must solve. In a hundred years" time it will have been controlled. All the world will have been developed-even Antarctica. There will be large cities in Antarctica. We already have supersonic (超音速的) flight, but in a hundred years" time we will have supersonic land travel as well. We will have used up most of the earth"s land tobuild our cities, so floating cities will have been built. The Japanese already have plans for cities of this kind.And there will be cities under the sea. The first of these will have been completed. .

How soon will it be before robots become so intelligent that will be able to do things, such as teaching languages or looking after patients in hospital? Some experts believe this will happen within twenty years while others disagree. One London company, UAS (Universal Automated Systems) has already developed machines that can be used as "home helps" for old people unable to look after themselves and who are living on their own or in special homes.These machines can now do such things as cooking eggs and cleaning the floor, and the company says that future models still accept simple voice instructions and be controlled by a " brain" that is the equivalent(当量) of the latest IBM microcomputer. The director of USA, Mr Henry Jeffries, believes that in the next five to ten years companies will have developed even more sophisticated(复杂的) robots for use in industry. By this time, it is likely that they will also have begun to sell new forms of these machines into ordinary homes. Robots could do a wide range of household tasks, such as preparing meals, washing dishes, cleaning the house and so on. By then, the price of such machines may have come down to as little as $1 000. But Dr Sandra Lomax, who has done research into artificial(人工的) intelligence at Sussex University and MIT ( Massachusetts Institute of Technology) believes we have a long way to go before we can develop truly intelligent machines, "Preparing an omelette (煎蛋) may seem easy enough. But suppose one of the eggs has gone bad, even the most "intelligent" robot would probably still use it. If something slightly unusual needs doing-something that requires even a little bit of ordinary human imagination, a robot is useless. They need programming for even the simplest of tasks and are not able to leam from experience. And teaching a robot how to recognize a bad egg is far more difficult than teaching it to prepare the omelette the egg goes into," she says.
1. Which of the following is the best title for this passage?
A. Servants of the Future B. How to Make Robots C. Robots More Clever Than Man D.The Robots and People
2. Dr Sandra Lomax thinks that . .
A. no robot will ever be able to prepare an omelette B.a robot will soon be able to do unusual house- work people can"t do C. we can programme a robot to learn from experience D. making an omelette is easier for a robot than recognizing a bad egg
3. Which of the following statements is TRUE according to this passage?
A. All experts agree that there will soon be robots that can teach languages and look after patients in hospital. B. Dr Sandra Lomax believes there are very great problems in developing intelligent robots. C. Robots have taken an important part in people"s daily life. D. Such machines are already being sold into ordinary homes.
4. A London company called UAS has already developed a machine which _ .
A. can teach languages and care for the patients in hospital B. can help old people do certain jobs in the house C.is controlled by microcomputer "brain" D. can accept simple voice instructions
5. The director of UAS believes that in the next five to ten years new forms of machines will .
A. be able to "think" with their own brains and do anything with imagination B. cost much less than $1 000 C. be used more in ordinary homes than in industry D. do more housework

MIT researchers and their colleagues are working tofind out whether energy from trees can power a network ofsensors(传感器)to prevent spreading forest fires. What they learn could also raise the possibility of usingtrees as silent guards along the nation"s borders to discoverpotential threatssuchassmuggled (走私的 ) radioactivematerials. The U. S. Forest Service currently predicts and tracksfires with a variety of tools, including remotc automatcdweather stations. But these stations arc expcnsive andsparsely (稀疏地) distributed. Additionalsensors could savetrees by providing better local climate data to be used in fireprediction models and earlier warnings. However,rechargingor replacing batteries by hand at very hard-to-reach locationsmakes it impractical and costly. The new sensor system seeks to avoid this problem bydeveloping trees into a self-sustaining power supply. Eachsensor is equipped with a battery that can be slowly recharged using electricity produced by the tree. "A singletree doesn"t generate a lot of power, but over time thetrickle (细流 ) chargeaddsup, justlike "-", saidShuguang Zhang, one of the researchers on the project andthe associate director of the MIT" s Center for Biomedica}Engineering( CBE). " The system produces enough electricity to allow the temperature and humidity sensors to wirelessly send outsignals four times a day,or immediately if there"s a fire.Each signal spreads from one sensor to another, until itreaches an existing weather station that sends the data bysatellite to a forestry command center in Boise,Idaho. Scientists have long known that trees can produceextremely small amounts of electricity. But no one knew exactly how the energy was produced or how to takeadvantage of the power.
1. What are the disadvantages of the remote automatedweather stations? a. They cost too much. b. They are of poor quality. c. They are not enough. d. They can"t reach remote places.
A. a,b B. b,d C. a,c D. b,c
2. Which of the following is the best sentence to fill in theblank?
A. Far water does not put out near fire. B. All rivers run into sea. C. Many a little makes a miracle. D. It never rains but it pours.
3. What would be the best title for the passage?
A. Preventing forest fires with tree power B. Trees can produce electricity C. Tree power in daily life D. Developing new energy

There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal-combustion engine (内燃机) has something to do with burning fuel, expanding gases and pistons (活塞) being driven. For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computer"s impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy (读写能力); it is a trade skill that should not be taught as a liberal art. Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repair and violin-making. Learning how to use a computer is not that difficu1t, and it gets easier all the time as programs become more "user-friendly". Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen. What does the phrase "learning to use a computer" mean? It sounds like "learning to drive a car", that is, it sounds as if there is some set of definite skills that, once acquired, enable one to use a computer. In fact, "learning to use a computer" is much more like "learning to play a game", but learning the rules of one game may not he1p you play a second game, whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished.
1. To be the competent citizens of tomorrow, people should.
A. try to lay a solid foundation in computer science B. be aware of how the things that they use do what they do C. learn to use a computer by acquiring a certain set of skills D. understand that programming a computer is more essential than repairing a car.
2. In the second paragraph "violin-making" is mentioned to show that .
A. programming a computer is as interesting as making a violin B. our society needs experts in different fields C. violin-making requires as much skill as computer programming D. people who can use a computer don"t necessarily have to know computer programming
3. Learning to use a computer is getting easier all the time because .
A. programs are becoming 1ess complicated B. programs are designed to be convenient to users C. programming is becoming easier and easier D. programs are becoming readily available to computer users
4. According to the author, the phrase "learning to use a computer" in Para. 3means learning.
A. a set of rules B. the fundamentals of computer science C. specific programs D. general principles of programming
5. The author"s purpose in writing this passage is .
A. to stress the impact of the computer on society B. to explain the concept of computer literacy C. to illustrate the requirements for being competent citizens of tomorrow D. to emphasize that computer programming is an interesting and challenging job.
