8、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 in hospital? Some experts believe this will happen within twenty years while other disagree.One London company, UAS (Universal Automated Syste
9、ms) 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 sim
10、ple voice instructions (指令) 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 tim
11、e, 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 $ 100
12、0.But Dr. Sandra Lomax, who has done research into artificial intelligence ( 人工智能 ) at Sussex University and MIT (Massachusetts Intelligence 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 o
13、ne of the eggs has gone bad, even the most intelligent robot would probably still use it. If something slightly unusual needs doingsomething 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 lea
14、rn 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.21. A London company called UAS has already developed a machine which_.A. can teach languages and care for the patients in hospitalB. can hel
15、p old people do certain jobs in the houseC. is controlled by microcomputer brainD. can accept simply voice instructions22.

There will be large cities in Antarctica. We already have supersonic (超音速)flight, but in a hundred years time we will have supersonic
22、 land travel as well.We will have used up most of earths land to build 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.26. We will have developed _in a hu

25、 fruit, according to research.Using date of the British Department of Environment on pesticides on fruit collected from supermarkets) scientists thought that each day some children would get a poisonous level of pesticides.The research, published on Sunday, says the government repeatedly claims that
26、 the levels of pesticide are safe because, instead of measuring individual apples, researchers buy 10, crush them and take an average reading to see if they are safe. This is the internationally agreed method of checking remains.But government figures show that the pesticide is not averagely spread
27、across the batch (一批),and one or two apples could contain 90% or more of the pesticide in the batch.It used mathematical modeling to measure exposure (暴露) to pesticides for children aged between 18 months and four years old. The pesticides involved can destroy childrens hormones and some are suspect
28、ed (怀疑)of causing cancer.The good news for British fruit growers is that samples grown in this country had lower residue level than imported fruit, so buying home-produced fruit will reduce the danger, said Emily Diamand, one of the Earths senior food researchers and one of the authors of the report

We may be living in beautiful cities. We may be getting far more sunlight, breathing fresher air, living in
48、better buildings and leading far better lives than we are today.Life will certainly have become far more mechanized (机械化的). It may even have become too mechanized. Mechanisation has already caused quite a few problems and will cause still more. For example, many jobs will have been automated That is
49、, machines will be doing many jobs that people do today. People will no longer be able to learn only one job in their lifetimes. They will have to learn several. Many of the jobs that young people are doing today will have become unnecessary by the time they are forty. This problem will have grown i

The writers attitude towards future automation is_.A. indifferent B. negativeC. concerned D. more than happyCEach child has his
52、 individual (个人的)pattern of social, as well as physical, development. Some of it depends on his home life and his relationships with the people who love him. Children in large families learn how to get along with others through normal brother-sister play and tussle (打头). An only child, on the other
53、hand, may have to learn his lessons in social living through hard experiences on the playground or in the classroom. Twins who always have one another to lean on may be slow in responding to others because they do not need anyone else.A child who is constantly scolded and made to feel he does everyt
54、hing wrong may have a difficult time developing socially. He may be so afraid of displeasing the adults around him that he keeps to himself( where he cant get into trouble) or he may take the opposite route and go out of his way to create trouble Like the deserted child, he too may return to infanti
55、le(幼稚的)pleasures, developing habits that will satisfy him, but create barriers(障碍)toward social contact.28.
