In recent years many countries of the world have been faced with the problem of how to make their workers more productive . Some experts claim the answer is to make jobs more varied. But do more various jobs lead to greater productivity ?There is evidence to suggest that while variety certainly makes the worker's life more enjoyable ,it does not actually make him work harder . As far as increasing productivity is concerned, then variety is not an important factor.

Other experts feel that giving the worker freedom to do his job in his own way is important ,and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way .Thus while freedom of choice may be important ,there is usually very little that can be done to create it .

Another very important consideration is how each worker contributes to the product he is making .In most factories the worker sees only one part of the product .Some car factories are now experimenting with having many small production lines rather than one large one ,so that each worker contributes more to the production of the cars on his line .It would seem that not only is degree of the worker contribution an important factor, therefore ,but it is also one we can do something about .

To what extent does more money lead to greater productivity ?The workers themselves certainly think this is important. Maybe they want more money only because the work they do is boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we succeed in making their jobs more interesting ,they will neither want more money ,nor will shorter working hours be so important to them.

Which of the following is the best way to make workers work harder according to the author?

       A.Increasing their pay.

       B.Giving them more spare time.

       C.Making the work itself meaningful.

       D.Replacing large production lines with small ones .

The reason why a worker cannot have freedom in doing the job in his own way is that       .

       A.the machinery is so badly needed that more of it should be bought

       B.there are production lines in factories

       C.the bosses can create very little freedom of choices

       D.the machines must be operated strictly according to instructions and rules

Besides money, what may make workers work more actively?

       A.Extra free hours.            B.More comfort of life.

       C.Interesting jobs.              D.Better working conditions.

The best title for this passage may be             .

       A.Problems of Modern Workers       B.Making Jobs More Interesting

       C.Pushing Workers to Produce More        D.How to Improve Labor Productivity.

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect" - holding in heat reflected from the earth and 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 cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.

Another view, less widely held, is that increasing particulate (废气排往空中而形成的微粒、颗粒) matter in the atmosphere is blocking 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 new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.

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 damaging effects on health

    D. existed merely in urban and industrial areas

As far as the greenhouse effect is concerned, the author ______.

    A. shares the same view with the scientists

    B. is uncertain of its occurrence

    C. rejects it as being ungrounded

    D. thinks that it will destroy the world soon

The underlined word “offset" in Para. 2 could best be replaced by______.

    A. slip into    B. make up for  C. set up   D. catch up with

This passage is mainly concerned with ______.

    A. the greenhouse effect                B. the burning of fossil fuels

    C. the potential effect of air pollution    D. the possibility of a new ice age

Like distance runners on a measured course,all of us will move through time in a roughly predictable pattern.

In the first stage of our lives,we develop and grow, reaching toward the top of physical vitality(活力).

After we grow up,however, the body begins a process of gradually wearing out.

A new awareness of physical fitness may help lengthen our years of health and vitality,yet nothing we do will work to stop the unavoidable force of aging.

Most of the changes of aging take place deep inside the body.The lungs become less able to take in oxygen.Powerful muscles gradually lose their strength.The heart loses power and pumps less blood.Bones grow easier to break.

Finally, we meet a stress,a stress that is greater than our physical resistance.Often,it is only a minor accident or chance infection(a disease caused by virus),but this time,it brings life to an end.

In 1932,a classic experiment nearly doubled the lifetime of rats,simply by cutting back the calories in their diet The reason for the effect was then unknown.

Today, at the University of California at Berkley, Dr.Paul Seagle has also greatly lengthened the normal lifetime of rats.The result was achieved through a special protein limited diet,which had a great effect on the chemistry of the brain.Seagle showed that within the brain,specific chemicals control many of the signals that influence aging.By changing that chemical balance,the clock of aging can be reset.

For the first time, the mystery of why we age is being seriously challenged.Scientists in many fields are now making striking and far-reaching discoveries.

An average lifetime lasts 75 years,yet in each of us lies a potential for a longer life.If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years.

1.What does the underlined word “it” refer to?

A.Physical vitality.   B.Stress.           C.Aging.           D.Physical resistance.

2.Which of the following is not a change of aging?

A.People gradually lose their muscle strength.

B.Bones tend to break more easily.

C.The heart loses power and pumps less blood.

D.The lungs become unable to take in oxygen.zxxk

3.The author believes the following except that     

A.human's life pattern is predictable

B.physical fitness can't stop the force of aging

C.human's lifetime will last longer than 75 years

D.all of the changes of aging take place deep inside the body

4.How did Dr.Paul Seagle lengthen the lifetime of rats in his experiment?

A.By keeping their physical fitness.          B.By cutting the calories in their diet.

C.By resetting their clock of aging.           D.By limiting the protein in their diet.

5.What is probably the best title for the article?

A.Two Great Experiments

B.The Mystery of Human Life

C.The Breakthrough in the Study of Aging

D.Ways to lengthen Human Life
