Every few years comes a fitness trend that has people scratching their heads in amazement. “Crunning” will probably be one of them. The “c” stands for “crawling”(爬行). This new sport needs two-legged humans running on all fours!
The funny idea is the brainchild of Shaun McCarthy. The 34-year-old is convinced that it will revolutionize fitness as we know it. According to the sports enthusiast, “The only thing that crunning’s changed about fitness is that it’s changed everything about fitness.”
Mccarthy has no scientific evidence to prove that crunning is more efficient than traditional two-legged running. However, he believes it is a more effective way to exercise because it puts an emphasis on the shoulders and arms, providing a complete body workout. Mccarthy also says crunning seems to tire him out more. He therefore concludes that the unconventional exercise is a bigger calorie burner than normal running.
While experts generally agree that crunning may provide a better workout, many are not sure if it is the right exercise for humans. Fitness coach Kevin Dean says we are not built to be on all fours and our wrists are therefore not as strong as our ankles. He believes crunning, which he calls a fad(时尚), could result in bad wrist and shoulder injuries, not to mention broken noses.
But McCarthy is not worried. Since the release of his crunning video a few weeks ago, many Melbourne residents have been seen scampering around on all fours. As it turns out they are not the only ones. In the Chinese city of Zhengzhou, crawling, a much slower version of crunning, has been a favorite activity for many years. According to some enthusiasts, the light exercise that is believed to date back two thousand years to the Han Dynasty, is good for curing back and spine ailments.
Ready to give crunning try? Then Mccarthy recommends investing in some good shoes, hardy gloves and most important of all, a face mask!
1.What can we learn about crawling according to Kevin Dean?
A. Our ankles are stronger than our wrists.
B. Crawling is an efficient way to work out.
C. The city of Zhengzhou is the origin of crawling.
D. Crawling can burn more calories than normal running.
2.What does the author think of crunning?
A. Dangerous. B. Interesting.
C. Beneficial. D. Unbelievable.
3.Why does McCarthy suggest people wearing a face mask when crunning?
A. To amuse other people.
B. To avoid being recognized.
C. To protect the nose from being injured.
D. To prevent sweat dropping on the ground.
4.What is the text mainly about?
A. A new way of crawling.
B. A new trend of exercising.
C. A scientific discovery.
D. A traditional way to keep fit.

In recent years many countries have been faced with the problem of how to make their workers more productive. Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead to greater productivity? There is something to suggest that while variety certainly makes the worker's life more enjoyable, it does not make him work harder. So variety is not important.
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 very little that can be done to achieve this.
Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are said to be experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem then that the degree of worker contribution is important.
To what extent does more money lead to greater productivity? The workers themselves certainly think this is important, but perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if companies succeed in making workers' jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.
72. Which of the following things will not increase productivity?
A. Making jobs more varied.
B. Longer working hours.
C. Giving workers the freedom to do his jobs in their own way.
D. Increasing the workers' contribution to production.
73. The last sentence in this passage means that if companies manage to make workers' jobs more interesting, _________.
A. they will want more money
B. they will demand shorter working hours
C. more money and shorter working hours are important
D. more money and shorter working hours will not be so important to them
74. In this passage, the writer tells us _________.
A. how to make the workers more productive
B. possible factors leading to greater productivity
C. more money leads to greater productivity
D. how to make workers' jobs more interesting
75. The writer of this passage is probably a _____________.
A. teacher B. worker C. manager D. physics
