Questions （1）to（5） are based on the following passage:
What makes a person a scientist？ Does he have ways ---or tools ---of learning that are different from those of others？ The answer is no. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power saw is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the condition permit. What works under one set of conditions at one time mustwork under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was latter tested through investigation. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurement. Then the measurements are used to make mathematical calculations that may test his investigations.
（1）A sound scientific theory should be one that .
A) works under one set of conditions at one time and also works under the same conditions at other times
B) leaves no room for improvement
C) does not allow any change even under different conditions
D) can be used for many purposes
（2）What, according to the passage, makes a scientist？
A) The tools he uses.
B) His ways of learning.
C) The way he uses his tools.
D) The various tools he uses.
（3） Albert Einstein built up his theory of relativity through .
A) investigation
B) experiments
C) tests
D) mathematics
（4）“…Knowing how to investigate, how to discover information, is important to everyone.” The author says this to show .
A) the importance of information
B) the importance of thinking
C) the difference between scientists and ordinary people
D) the difference between carpenters and ordinary people
（5） What is the main idea of the passage？
A) Scientists are different from ordinary people.
B) The theory of relativity.
C) Exactness is the core of science.
D) Exactness and way of using tools are the key to the making of a scientist.
Let him correct his own papers.Why should we teachers waste time on such routine work？ Our job should be to help the child when he can't find the way to right answer.Let's end all this nonsense of grades, exams, marks.Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know.
Let them get on with this job in the way that seems most sensible to them.The idea that there is a body of knowledge to be learnt at school and used for the rest of one's life is nonsense in a world as complicated and rapidly changing as ours.Anxious parents and teachers say, “But suppose they fail to learn something essential, something they will need to get on in the world？” Don't worry! If it is essential, they will go out into the world and learn it.

There is no doubt that something of this kind will happen. The shorter working week, longer holidays, earlier retirement, job-sharing -- these and other ways of reducing the amount of time people spend on their jobs -- are certainly likely to spread. A mix of part-time paid work and part-time unpaid work is likely to become a much more common work pattern than today, and a flexi-life pattern of work -- involving paid employment at certain stages of life, but not at others -- will become widespread. But it is surely unrealistic to assume that this will make it possible to restore full employment as the dominant form. of work.
In the first place, so long as employment remains the overwhelmingly important form. of work and source of income for most people that it is today, it is very difficult to see how reductions in employees' working time can take place on a scale sufficiently large and at a pace sufficiently fast to make it possible to share out the available paid employment to everyone who wants it. Such negotiations as there have recently been, for example in Britain and Germany, about the possibility of introducing a 35-hour working week, have highlighted some of the difficulties. But, secondly, if changes of this kind were to take place at a pace and on a scale sufficient to make it possible to share employment among all who wanted it, the resulting situation --in which most people would not be working in their jobs for more than two or three short days a week -- could hardly continue to be one in which employment was still regarded as the only truly valid form. of work. There would be so many people spending so much of their time on other activities, including other forms of useful work, that the primacy of employment would be bound to be called into question, at least to some extent.
The author uses the negotiations in Britain and Germany as an example to
A．support reductions in employees' working time.
B．indicate employees are unwilling to share jobs.
C．prove the possibility of sharing paid employment.
D．show that employment will lose its dominance.
Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health.
The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.
The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution.
It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive.
6. According to the passage, food supplies have been increased by all the following except_____________.
A.pesticides
B.artificial fertilizers
C.improved varieties
D.transportation
7.How many chemicals are still less familiar to the scientists？()
A.20,000.
B.1,000
C.19,000
D.21,000.
8.Why will people prefer GM food in the future？()
A.Because it uses less pesticides.
B.Because it is much cheaper.
C.Because the production is increased.
D.Because it is organic food.
9.Which of the following is NOT true？()
A.By 2050, the world population will grow to ten or eleven billion.
B.In the 21st century, GM food will take the place of conventional food.
C.More and more people will reduce the overall land available for farming.
D.More and more people will consume more food and occupy more space.
10.The author’s attitude towards GM food is _______.
A.negative
B.positive
C.critical
D.uncertain
A.Convert the drive so that it is a spanned volume
