PALO AITO, California—“Switching off the television may help prevent children from getting fatter—even if they do not change their diet or increase the amount they exercise,” US researchers said last week.
A study of 192 third and fourth grades, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.91 kg) less over a one-year period than those who did not change their television diet.
“The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity,” said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
“American children spend an average of more than four hours per day watching television and videos or playing games, and rates of childhood being very fat have doubled over the past 20 years,” Robinson said.
In the study, presented this week to the Pediatric Academic Societies’ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continue their normal television viewing, even though neither group ate a special diet nor took part in any extra exercise.
“One explanation for the weight loss could be the children unstuck to the television may simply have been moving around and burning off calories,” Robinson said.
“Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more,” Robinson added.The purpose of the first two paragraphs is ______.

The young people who talk of the village as being “dead” are talking nothing but nonsense, as in their hearts they must surely know.
No, the village is not dead. There is more life in it now than there ever was. But it seems that “village life” is dead. Gone for ever. It began to decline about a hundred years ago. When many girls left home to go into service in town many miles away, and men also left home in increasing numbers in search of work, and home was where work was. There are still a number of people alive today who can remember what “village life” meant in the early years of the present century. It meant knowing and being known by everybody else in the village. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp oil and coal.
Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed（展现）to villagers. The long-established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating to make “village life” and “town life” almost alike. Now with the highly developed science and technology and high-level social welfare（福利）for all, there is no point whatever in talking any longer about “village life.” It is just life, and a better life.
Finally, if we have any doubts about the future, or about the many changes which we have seen in our lives, we have only to look in at the school playground any mid-morning; or see the children as they walk homeward in little groups. 0bviously these children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.

A new enemy is threatening Japanese traditions: leisure（闲暇）. As part of its attempt to increase imports, the government is trying to get people to work less and spend more. The workers are disgusted.
The figures support the western prejudice（偏见） that the Japanese are all work and no play. Trying to force workers away from their desks and machines, the government said last April that the country should cut down from its 2,100 hours average work year to 1,899 hours and a five-day week by 1992. Beginning in February, banks and stock markets will be closed on Saturdays, staff of civil service will be forced out of their offices two Saturdays a month. The government hopes that others will follow that practice.
But some persuasion will be needed. Small companies are very angry about it and they fear competitors may not cut hours. The unions are no happier: they have even advertised in newspapers arguing their case against the foreign pressure that is forcing leisure upon them. They say that shorter hours are a disguised（隐性的） pay cut. The industrialists, who have no objection to the government’s plans, admit that shorter hours will help them cut costs. Younger Japanese who are supposed to be acting against their hard-working parents, show no sign of wanting time off, either. But unlike older workers, they do spend money in their spare time. Not content with watching television, they dance, dress up, sit in cafes, go to pop concerts and generally drive the leisure-industry boom. Now that they know how to consume, maybe the West can teach them to relax and enjoy themselves, too.
68．The purpose of getting the Japanese to have more spare time is that .
A．the government wants to show more concern for the health of the people
B．the government needs to get more goods from abroad
C．the Japanese have been working too hard
D．the Japanese hope to change the western prejudice
69．The group of people who welcome the shorter-hour system in Japan is .
A．the small companies B．the industrialists
C．the unions D．the younger generation
70．The unions think that .
A．the shorter hours they work, the higher pay the can get
B．the more they work, the less leisure they can enjoy
C．the shorter hours they work, the less pay they can have
D．the greater pressure the government is forcing on them, the less happy they can be
71．The best title for this passage can be .
A．Oh no! Not Saturday Again! B．Leisure: the Greatest Threat!
C．Enjoy While You are Young! D．Less Work and More Play!
The following conversation is between Susan Russell-Robinson from the US Geological （地质学的）Survey and Barbara Reynolds from USA Today .
Q: Why , after 600 years of no activity , did Mount Pinatubo in Philippines erupt（喷发）in 1991 ?
A: Volcanoes （火山）each have their own eruption styles . This volcano probably has a rule which makes it erupt in the order of every 500 to 1000 years , but a volcano in Hawaii seems to erupt every year , and some of the Alaskan volcanoes might erupt every 10 or 20 years .
Q: So nothing caused it ?
A: There’s nothing out of the ordinary . If you were to take an ordinary calendar year , 50 to 75 or 80 volcanoes erupt around the world every year . There are 20 to 30 volcanoes every month that show signs of unrest . That might be a full-blown eruption or a whole host of activities like that .
Q: What is “the ring of fire” ?
A: If you look at where active volcanoes are placed around the world , there are somewhere between 500 and 600 of them . There is what appears to be almost a necklace that goes around the Pacific Ocean . It makes a ring where 60% of the world’s volcanoes lie .
Q: Why such a concentration（集中）there ?
A: That’s based on a theory that the oceans and the continents are like separate pieces . When they move , one might ride up over the other one . In this case , the Pacific Ocean goes under the continents and when that happens it seems to produce magma （熔岩）at depth and then you have volcanoes in the same ring .
64．What kind of writing do you think this passage is ?
A．A text taken from a geography book . B．An interview published in the press .
C．A conversation carried out in a film . D．An oral test recorded as an example .
65．Which of the following statements can correctly explain why we have so many volcanoes around the Pacific Ocean ?
A．The movement of the surface of the earth makes it possible.
B．The Pacific Ocean produces magma and presses it everywhere.
C．The oceans and the continents are separated from each other.
D．The earth’s surface around the Pacific is thinner than any other part.
66．Barbara Reynolds’ main purpose here is .
A．to show how dangerous volcanoes are to the world
B．to learn what signs a volcano gives us before its eruption
C．to warn the world of the existence of “the ring of fire”
D．to introduce some general idea of volcanoes to the public
67．Which of the following can be considered as the best conclusion of the conversation?
A．There are so many volcanoes in the world and we are always in danger.
B．Volcanoes have erupted more frequently than ever before.
C．Volcanoes are waiting to be better known.
D．Something must be done to protect the people near the ring of fire.

The human body is a living machine , and , like all machines , it needs “fuel” (燃料) to supply it with energy . This is provided by the food we eat . But how much do we need to stay healthy ?
The energy value of food is usually measured in calories . A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different , as the pictures show . Also , the number of calories you use at any one moment normally depends on the activity you are in . For example , you need more calories for standing than for sitting , more for running than for walking , and so on .
The energy in food is in the form of three kinds of chemical materials-carbohydrate （碳水化合物）, protein（蛋白质）and fat . Carbohydrate provides 3.8 Cal/gm , protein4.0 Cal/gm , and fat 8.8 Cal/gm . Each food contains different amount of these materials , as the round pictures show .
