lt, they do not only look younger and slimmer, but feel better. Because of increased physical fitness, life expectance in the nation has risen to seventy-three years, with fewer people suffering from heart disease, the nation"s number one killer.
Jogging ( 慢跑 ), the easiest and cheapest way of improving the body, keeps over 30million people of all ages on the run. For the price of a good pair of running shoes, anyone anywhere can join the race.
Dieting, too, has become a national pastime. Promoters of diets that eliminate eating one thing or another, such as fats or carbohydrates ( 碳水化合物 ), promise as much as 20- pound weight losses within two weeks. Books describing such amazing diets always head up ( 居……之首 )the best-seller lists because people who are overweight want to lose weight quickly and easily.
Nevertheless, jogging and dieting, carried to extremes, can be harmful. Many confused joggers overdo and finally suffer from ankle and foot damage. Dieting, fortunately, becomes only a temporary means for shedding a few pounds while the body lose the balanced nutrition ( 营养 )it requires, so most dieters cannot keep on diets. Above all, common sense should be the keystone for any dieting and exercise plan.
6.The main idea of this passage is that___________ .
A. both jogging and dieting can improve your health

B. exercise and dieting bring about spiritual as well as physical well-being
C. people don"t stay on a diet because it doesn"t work
D. a 20-pound weight loss within two weeks is too much for the body

举一反三
Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slowmoving. There are some aspects(方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.
For those who do not particularly enjoy competitive sports — and it is especially difficult to do so if you are not good at them — there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.
Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activityphysical effort on the one hand and relaxation on the other — which were the natural way of life of our forefathers.
12. Pollution, noise and stress are examples of _____.
A. causes of unfitness
B. bad features of living in towns
C. the things we can completely do away with
D. unavoidable things in town
13. We don’t get much out of separate sports because we _____.
A. don’t do them very often
B. don’t do them actively enough
C. find it hard to get out of our armchairs
D. don’t find them interesting
14. To be healthy we must _____.
A. keep fit and active B. keep fit and learn to relax
C. be active and practise Yoga D. have a sound mind
15. Our forefathers were healthy because______.
A. their way of life closely connected with both exercise and relaxation
B. they were careful to get plenty of fresh air
C. they spent most of the time out of doors
D. their environment was not polluted
Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year"s Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country"s economic troubles.
"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped(fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It"s made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.
19. What can we learn from the first paragraph?
A. Bicycles are the best way to go about
B. Bikes should be made more comfortable to ride.
C. You can improve your bicycle for science research.
D. Many inventions are connected with the bicycle.

A. ISEF is an exhibiton displaying bicycle experiments designed by students.
B. Looking closely at things you are concerned about can lead to scientific research.
C. Renato’s improvement of the bicycle has solved the country’s great problem.
D. Renato’s special bicycle will soon be put into use in remote areas.’
21. The underlined word “address” in the third paragraph probably has the same meaning as _______.
A. make address written B. give up C. work at D. speak at
22. Renato’s special Multibike has all the following EXCEPT ________.
A. making knives sharp B. mixing any kind of drinks
C. producing electricity D. operating a machine with its own electricity
23. It can be inferred that Renato’s special bicycle is mainly designed for ________.
A. distant areas in the rainforest without electricity.
B. the use of his own family to make life easier.
C. the competition of ISEF to win money to support remote rainforests
D. enough exercise by pedaling it

This rapidly expanding youth population is increasingly vulnerable to HIV. Young people are at the center of the HIV/AIDS epidemic . Of the 10 million young people living with HIV worldwide, 21% live in Asia and the Pacific region. When surveying of all new HIV/AIDS cases globally, nearly a quarter of all people living with HIV/AIDS are under the age of 25. An estimated 6,000 young people are infected every day — one every 14 minutes. The majority are women and girls. In South Asia, where over 1 million young people between t
he ages of 15 to 24 are infected with HIV, more than half (62%) are young women. Young people are key to defeating the HIV/AIDS epidemic. Yet in most countries, they lack the information, education and services that will enable them to make informed and healthy choices about their health, and the needs of youths are often ignored. UNESCO, in collaboration with other UN agencies, governments, NGOs and community-based organizations, makes efforts to ensure the health needs of youths, including HIV prevention education, programs and policies implemented throughout Asia and the Pacific region.
59. How many young people with HIV live in Asia and the Pacific area?
A. 3 billion B. 850 million C. 100 million D. 2.1 million
60. Which of the following statements is NOT true?
A. It’s young people themselves that can defeat HIV.
B. Most cases infected with HIV are young people.
C. Most young people who are infected with HIV are women.
D. Half of the world population is infected with HIV.
61. From the passage we can conclude that ________.
A. more and more young people will be infected with HIV
B. it’s because of not being informed that young people are easy to be infected
C. people in Asia and the Pacific region are easy to be infected
D. there is no policy for teenagers’ prevention of HIV
