Today just as technology changed the face of industry, farmers have undergone an "agricultural revolution". On the farm of today, machines provide all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog(豬) producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear(修剪) sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the special barn(畜棚), then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.

  Making connections. This technique involves taking   15  ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words  16  with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the   17 to the job you have to do. So imagine you want to buy a friend an original   18  ; you could buy him tickets to match or take him out for the night.
  NO limits! Imagine that normal limitations don’t   19  . You have as much time /space / money, etc. as you want. Think about your goal and the new  20  .

Now   22   this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a    23  point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the  24   in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their    25 .

Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
In some modern countries it has for some time been fashionable to think that by free education for all — one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think “l(fā)ow” work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.
小題1:The writer of the passage thinks that _______.
A.education can settle most of the world’s problems
B.free education for all probably leads to a perfect world
C.free education won’t help to solve problems
D.a(chǎn)ll the social problems can’t be solved by education
小題2:The writer wants to prove that _______.
A.our society needs all kinds of jobs
B.our society needs free education for all
C.a(chǎn) farmer is more important than a professor
D.work with hands is the most important
小題3:The purpose of education is _______.
A.to choose officials for the country
B.to prepare children mainly for their future work
C.to let everyone receive education fit for him
D.to build a perfect world
小題4:The passage tells us about _______ of the education.

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds (揮發(fā)性化合物) —— chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from such volatile compounds to attract insects such as bugs and bees.
Plants can also discover  volatile compounds produced by other plants. A tree under attack by hungry insets, for instance, may give off these chemicals in order to let other trees know about the attack. In response, the other trees may send off their chemicals to keep the bugs away —— or even chemicals that will attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical sensor (傳感器) called an “electronic nose”. The “e-nose” can tell such compounds as plants make. When plants are attacked, scientists say, the e-nose could help quickly decide whether plants are being eaten by insects. But today, the only way to spot such insects is to inspect individual plants by observing them. This is a challenging task for managers of greenhouses, including those that can house thousands of plants. The research team is working with an e-nose that can recognize volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds based on the interactions (相互作用), and then the e-nose will give off electronic signals that the scientists can analyze by using computer software.
To test the e-nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all being common greenhouse crops. Then scientists collected samples of the air around damaged leaves from each type of crop. These plants had been damaged either by insects or by scientists who made holes in the leaves with a hole punch (打孔器).
The e-nose, it turns out, can identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage —— by insects or with a hole punch —— had been done to the tomato leaves.
With some fine-tuning (微調(diào)), a device like the e-nose can one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this can also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, India, who studies smells of flowers and plants. Hopefully, scientists believe, the device can bring large benefits to greenhouse managers in the near future.
小題1:We learn from the text that plants communicate with each other by ______.
A.making some sounds
B.waving their leaves
C.producing some chemicals
D.sending out electronic signals
小題2:What did the scientists do to find out if the e-nose worked?
A.They fixed 13 sensors inside the device.
B.They presented it with all common crops.
C.They collected different damaged leaves.
D.They do tests on damaged and healthy leaves.
小題3:According to the writer, the most amazing thing about the e-nose is that it can ______.
A.pick out ripe fruits quite expertly
B.spot the insects in a very quick way
C.tell different damages to leaves
D.recognize unhealthy tomato leaves
小題4:We can infer from the last paragraph that the e-nose ______.
A.is unable to tell the smell of flowers
B.is not yet tested in greenhouses
C.is designed by scientists at Purdue
D.is helpful in killing harmful insects

Computer people talk a lot about the need for other people to become “computer-literate.” But not all experts (專家) agree that this is a good idea.
One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer. David does not see it that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them “people-literate.” David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do, they find out.The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don’t have to learn computer terms(術(shù)語), but the experts have to explain in plain language. The computers are becoming “people-literate.”
小題1:Which of the following is David Tebbutt’s ides on the relationship between people and computers?
A.Computer learning should be made easier.
B.There should be more computer clubs for experts.
C.People should work harder to master computer use.
D.Computers should be made cheaper so that people can afford them.
小題2:We can infer from the text that “computer-lilerate” means_______.
A.being able to afford a computer
B.being able to write computer programs
C.working with the computer and finding out its value
D.understanding the computer and knowing how to use it
小題3:The underlined word “it” in the second paragraph refers to the idea that Computertowns ___.
A.help to set up more computer clubs
B.bring people to learn to use computers
C.bring more experts to work together
D.help to sell computers to the public
小題4:David Tebbutt started Computertown UK with the purpose of______.
A.making better use of computer expert

An increase in students applying to study economics (經(jīng)濟(jì)學(xué)) at university is being attributed to (歸因于)the global economic crisis (危機(jī)) awakening a public thirst for knowledge about how the financial system works.  
Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up.  
Professor John Beath, the president of the society and a leading lecture at St Andrews University, said his first-year lectures which are open to students from all departments—were drawing crowds of 400, rather than the usual 250.  
“There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to relate my teaching to contemporary events in a way that one hasn’t traditionally done. ” He added.   
University applications rose 70% last year. But there were rises above average in several subjects. Nursing saw a 15% jump, with people’s renewed interest in careers in the pubic sector(部門), which are seen as more secure in economic crisis.  
A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain.  
Zack Hocking, the head of Child Trust Funds, said: “It’s possible that one good thing to arise from the downturn will be a generation that’s financially wiser and better equipped (使…有能力) to manage their money through times of economic uncertainty.”
小題1:Professor John Beath’s lectures are            .  
A.given in a traditional way
B.connected with the present situation
C.open to both students and their parents
D.warmly received by economics
小題2: Careers in the public sector are more attractive because of their        .
A.greater stabilityB.higher pay
C.fewer applications D.better reputation
小題3:In the opinion of most parents ,           .  
A.economics should be the focus of school teaching
B.more students should be admitted to universities
C.the teaching of financial matters should be strengthened.
D.children should solve financial problems themselves
小題4:According to Hocking , the global economic crisis might make the youngsters_____.
A.wiser in money management
B.have access to better equipment
C.confident about their future careers
D.get jobs in Child Trust Funds
小題5:What’s the main idea of the text?
A.Universities have received more applications.
B.Economics is attracting an increasing number of students
C.college students benefit a lot from economic uncertainty
D.parents are concerned with children’s subject selection.

If California were not already so famous for Sillicon Valley(硅谷) and Hollywood, it might be well-known for the groups of water-technology firms in its San Diego County. The reverse-osmosis (RO) spiral module, the technique that supports turning seawater and waste-water into drinkable stuff, began in San Diego in 1964. Today dozens of firms in the area supply many of the world's approximately 13,000 RO plants in places from the Persian Gulf and Israel to Australia and China.
Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south-west faces a water problem. But now as the climate gets warmer and the population increases, there is more agreement that the existing infrastructure, consisting of vast pipes that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not be enough. In places such as San Diego, which has inadequate and salty groundwater and currently imports 90% or its water, the answers must be greater conservation, reusing as much water as possible, and getting most of the rest from the sea.
The first part, conservation, has been widely accepted by the public. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling has been a hard sell, because of an unpleasant factor. Americans still use the term “toilet-to-tap” for recycling, even though properly treated waste-water is nowadays completely clean. Singapore made its programme acceptable in part by renaming it as NEWater.
This is where desalination comes in, which means taking the salt out of salt water. A firm called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling, so Poseidon plans to change 104m gallons a day by using the RO spiral module.
Lots of people like the idea. Once fully running in 2015, the plant could produce 10% of the region's water. And there are plans for more desalination plants. Many places would need to take much less water from the endangered Colorado River. But a few people hate it a lot. Joe Geever, an expert in biology, says desalination uses too much energy and that Poseidon plant would kill too much sea life. He understands that there is a role for desalination, he says, but would rather not have it right there, right now, and on this scale.
小題1:Which of the following is WRONG about the RO spiral module according to the passage?
A.This technology is not widely used in its birthplace.
B.Today there are about 13,000 RO plants in the Persian Gulf, Israel, Australia and China.
C.This technology can be used in desalination plants to make sea water drinkable.
D.It is a promising water treatment technology welcomed by a lot of people.
小題2:How many solutions to the water problem in San Diego are mentioned in the article?
A.2.B.3.C.4.D.5.
小題3:What can we infer from the article?
A.The Colorado River is the main water source for California.
B.Americans still use the term “toilet-to-tap” for recycling water.
C.NEWater serves as a brand for recycled clean water in Singapore.
D.Poseidon Resources stands for the power station by the beach in Carlsbad.
小題4:What is Joe Geever's attitude toward building a large desalination plant at present?
A.Supportive.B.Negative.C.Optimistic.D.Vague.

Our surroundings are being polluted faster than nature and man’s present efforts cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going—and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.
小題1:Man cannot prevent the world from being polluted mainly because______.
A.the population of the world is decreasing fast
B.people use too many man-made materials
C.we have more and more industry
D.we are producing more cars, trucks and buses
小題2:According to the passage, what does man value most?
A.Industry.B.Health.
C.Clean air.D.The future of the children.
小題3:The story about the airline pilot tells us that ______.
A.man knows where the society is going
B.people do not welcome the rapid development of modern society
C.man can do little about the problem of pollution
D.the writer is worried about the future of our society
小題4:People crowd into the cities because ______.
A.they want very much to find well-paid jobs
B.they are anxious to enjoy the achievements of our society
C.they have become tired of their homeland
D.they have a strong wish to become industrial workers
