题型:不详难度:来源:
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
答案
12---15 BBBA
解析
12.B 细节理解题。根据There are some aspects 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. 可知pollution, noise, stress是生活在城市一些不健康的、不太好的方面。
13.B 推断判断题。根据What often happens though is that you do them in such a leisurely way, so slowly... 可知,我们锻炼的时候并不是太积极和投入,故效果不太理想。
14.B 推断判断题。根据you must also master the art of complete mental and physical relaxation等处可知,光是锻炼是不够的,还要注意心理保健。健康包括生理的和心理的(锻炼和心理放松)两个方面。故B项最佳。
15.A 推断判断题。根据physical effort on the one hand and relaxation on the other — which were the natural way of life of our forefathers.可知,我们祖先的生活方式很健康,是因为他们的生活方式与锻炼和放松密切相关。

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.
20. Which of the following is true according to the passage?
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
If you do not use your arms or your legs for some time, they become weak. When you 1using them again, they 2become strong again. Everybody knows this and nobody would think of 3 this fact. 4 there are many people who do not 5 to know that memory works in the 6 way.

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

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.

On May 21,1999,some American scientists were working at the computers to look for information they needed.Suddenly they saw a lot of very bright red spots crossing the computers’screens.At the same time the computers were working much slower.To find out what was happening they stopped their work to check some parts of the computers.To their horror,they found out that most of their stored information was got rid of by computer virus! Obviously all these computers had been infected by computer virus.
It is said that the computer virus was made by two or three Philippine young men fond of playing tricks.They all had excellent education.They created the virus just to show their intelligence.The kind of computer virus is named“I Love You”Virus.This virus can hide in computers for long.When the time comes it will attack the computers by lowering the important functions,damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store;even worse,it still can reproduce itself in great quantities within a short time.
We come to know that “I Love You”Virus of
