Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedrooms TVs.
A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood. But the results don’t prove that TV is the cause and don’t rule out that already poorly motivated youngsters(年轻人)may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2½ hours for those who had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest, while those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn’t have TVs in their bedrooms.
1. According to the California study, the low-scoring group might____________.
A. have watched a lot of TV B. not be interested in math
C. be unable to go to college D. have had computers in their bedrooms
2.What is the researchers’ understanding of the New Zealand study results?
A. Poorly motivated 26-year-olds watch more TV.
B. Habits of TV watching reduce learning interest.
C. TV watching leads to lower education levels of the 15-year-olds.
D. The connection between TV and education levels is difficult to explain.
3. What can we learn from the last two paragraphs?
A. More time should be spent on computers.
B. Children should be forbidden from watching TV.
C. TV sets shouldn’t be allowed in children’s bedrooms.
D. Further studies on high-achieving students should be done.
4. What would be the best title for this text?
A. Computers or Television
B. Effects of Television on Children
C. Studies on TV and College Education
D. Television and Children’s Learning Habits
A small piece of fish each day may keep the heart doctor away．That's the finding of a scientific study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce（盎司）of salt water fish per day than those who never ate fish.
The Dutch research is one of three human studies that hold the belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year．But researchers previously have noticed that the incidence （发生率） of heart disease is lower in cultures that consume more fish than Americans do．There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.

For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, the average fish consumption was about two-thirds of an ounce each day with more men eating thin fish than fatty fish.Contrary to the impression that grandmothers are delighted to help their grown daughters and care for their grandchildren, a study of multigenerational families shows that many older women hate the frequent demands that the younger generations make on their time and energy．
“Young women with children are under a lot of pressure these days, and they expect their mothers to help them pick up the pieces,” noted Dr．Bertram J．Cohler, a behavioral scientist at the University of Chicago．“This is often the strongest source of complaint on the part of Grandmother, who has finished with child caring and now has her own life to live．Grandmothers like to see their children and grandchildren, but on their own time．”
Dr．Cohler is director of a study, sponsored by the National Institute of Aging, of 150 workingclass families that live in a Midwestern suburb．He and Dr．Henry U．Gruebaum of Harvard Medical School, have already completed their study of four such families in New England．
Dr．Cohler tells of a middle-aged Boston woman who works as a cook all week and for her parish（教区） on Sundays．Every Saturday, her one day off, her daughter and family visit, expecting mother to make lunch, shop, and visit．“That's not how she wants to grow old,” said Dr．Cohler, who was told by the older woman, “My daughter would never speak to me if she knew how angry and unhappy I get．”
In all the four New England families studied, the older women disliked the numerous phone calls and visits from their grown daughters, who often turned to the mothers for advice, physical resources, love, and companionship as well as baby-sitting services．“American society keeps increasing the burdens for older people, particularly those in their 50s and 60s,” Dr．Cohler said in an interview here．“They're still working and they're taking care of their grown children and maybe also their aged parents．Sometimes life gets to be too much．”
67．Which of the following is closest in meaning to the expression “pick up the pieces” in the second paragraph?
A．Save a bad situation． B．Put children's toys in their proper places．
C．Gather up pieces of clothing． D．Keep the room in good order．
68．The middle-aged Boston woman ______．
A．expects her mother to cook lunch for her
B．enjoys the room in good order
C．visits an older woman every Saturday
D．works six days a week
69．The passage is mainly about ______．
A．young women's inability to look after their children
B．Grandmothers' attitudes toward helping their grown daughters
C．average American women's family life
D．grandmother should give more help to their daughters
70．From Dr．Cohler's study we may reach the conclusion that ______．
A．daughters should be independent of their old grandmothers
B．grandmother should give more help to their daughters
C．mothers and daughters should support each other
D．daughters should be more considerate toward their mothers
It is natural that children are curious about the world around them．For example, they want to know how their hearts beat．They want to know why the ocean water tastes salty．
As children grow up, they become curious about different kinds of things．When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers．They become interested in the physical world around them: the plants, the animals, the sky．Later, they become interested in the things that people have made: wheels, bicycles, cars．And when they are adults, their curiosity continues．Sometimes this curiosity leads to a career in science．
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the sky．Other scientists who study living things work with the biological sciences．A third group of scientists study the physical sciences, e．g．physics, chemistry ．
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run．They say that when you are quiet, your heart normally beats 65 or 75 times a minute．Your heart is a pump that pumps blood to all parts of the body．The blood carries oxygen and nutrition．When you run, your muscles work very hard and use the nutrition that the blood carries to them．The muscles need oxygen, too．So your brain sends a signal to the heart．The signal means that the muscles need more nutrition and oxygen．Then the heart beats fast and sends blood quickly to the muscles．It may beat 90 to 140 times a minute．
Of course, scientists cannot answer all of our questions．If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks．When a rock gets very hot or very cold, it cracks．Rain falls into cracks．The rain then carries the salt into the earth and into the rivers．The rivers carry the salt into the ocean．But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year．” Scientists are not sure about the answer to this question．
We know a lot about our world, but there are still many answers that we do not have, and we are curious．

第三部分：阅读理解（共20小题，共40分）
第一节（共15题, 每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A,B,C和D）中，选出最佳选项。
We often hear the phrase: “You have a greater chance of being struck by lightning．”It is used to describe something that hasn’t got much chance of happening．However, the common saying undermines（掩盖）the very real dangers of lightning．
Last Friday, at least 5 people were killed by lightning in Nepal（尼泊尔）．
Lightning strikes are the second most common cause of deaths during natural disasters in the US．The first is floods．Around 400 people nationwide are struck by lightning each year, and of those, 70 people die．That is, more people are killed by lightning than by tornadoes and hurricanes．
Because lightning kills only one or two people at a time, its danger does not receive as much attention as other disasters．
“If you hear thunder, you are in danger from lightning, ”said Rocky Lopes, a disaster educator at the American Red Cross．
“Thunder means that lightning is close enough to hit you at any time, so you should move indoors immediately and stay there until the storm has ended．The most important thing to remember is to seek shelter,”Lopes said．
Summer is the peak time for lightning storms, so when lightning strikes across the sky, remember these safety tips:
*Stop working, fishing, swimming or playing in open fields．
*Do not stand under a tree．
*Get off bicycle and motorcycles．
*Crouch down（蹲下）if there is no shelter．
*Avoid open spaces, wire fences, metal objects and electrical objects such as hair driers．
56．Of the people who are struck by lightning each year in the U．S．A．, about ____ people are lucky enough to continue to live．
A．400 B．330 C．70 D．5
57．If you hear the thunder, the most important thing you do is to _____．
A．find shelter to hide in B．stand still in the open spaces
C．stand under a tree D．stop working in the fields
58．Which of the following is NOT true?
A．If you hear the thunder, you needn’t move indoors right away．
B．Fewer than 70 people are killed by tornadoes and hurricanes each year in the U．S．A．
C．People don’t pay as much attention to the danger of lightning as that of floods．
D．Floods are the first most common cause of deaths during natural disasters in the U．S．A．
