If you think that running marathons will help you live a long and healthy life,new research may come as a shock.According to a recent scientific study,people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000 joggers(慢跑者) and non-joggers for 12 years.The death rates(率) from the sample group suggest that people who jog at a moderate(适合的) pace two or three times a week for less than two and a half hours in total are least likely to die.
The best speed to jog at was found to be about 5 miles per hour.The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers.The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉).Over time,this can cause serious injuries.
Peter Schnohr,a researcher in Copenhagen,said,“If your goal is to decrease(减少) risk of death and improve life expectancy,jogging a few times a week at a moderate pace is a good strategy(策略).Anything more is not just unnecessary,and it may be harmful.”
The implications(含义) of this are that moderate forms of exercise such as tai chi,yoga and brisk walking may be better for us than “iron man” events,triathlons(三项全能) and long-distance running and cycling.According to Jacob Louis Marott,another researcher in the study,“You don’t actually have to do that much to have a good impact(影响) on your health.And perhaps you shouldn’t actually do too much”.
1.The underlined word “strenuous” in Paragraph l is closest in meaning to“___________”.
A.hard B.regular
C.practical D.flexible(灵活的)
2.The author presents some figures in Paragraph 2 to ___________.
A.suggest giving up jogging
B.show risks of doing sports
C.provide supportive evidence(证据)
D.introduce the research process(过程)
3.According to the scientists,why is too much exercise harmful?
A.It may injure the heart and arteries.
B.It can make the body tired out.
C.It will bring much pressure.
D.It consumes too much energy.
4.What can be inferred from the text?
A.No exercise at all is the best choice.
B.More exercise means a healthier life.
C.Marathons runners are least likely to die.
D.Proper exercise contributes to good health.

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.
1. According to the passage, human death is now mainly caused by _______.
A. diseases and aging B. accidents and war
C. accidents and aging D. heart diseases and war
2. In the author's opinion, today's most important advance in technology lies in _____.
A. medicine B. the internet C. brain cells D. human organs
3. Humans may live longer in the future because ______.
A. heart disease will be far away from us
B. human brains can decide the final death
C. the basic materials of cells will last forever
D. human organs can be repaired by new medicine
4. We can learn from the passage that _____.
A. human life will not last more than 120 years in the future
B. human have to take medicine to build new skin cells now
C. much needs to be done before humans can have a longer life
D. we have already solved the technical problems in building new cells.
