听力原文: As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents. The power of the school has been replaced by the home. Studies have shown that factors like child's understanding of language, his learning patterns, and his curiosity are well established before the child enters school at the age of six. Studies have also shown that even after school begins, children's achievements have been far more influenced by parents than by teachers. This is particularly true about language learning.
However, it's sad to see that so many parents are not making the most of their child's intelligence. Until recently parents had been intimidated by educators who asked them not to educate their children. But many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.
Parents have been particularly afraid to teach reading at home. Of course, children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually and the easiest place to do this is at home. Many four-or five-year-old children, who have been shown a few letters and taught their sounds, will spontaneously make up single words of their own with these letters even before they have been taught to read.

听力原文: Not everybody reads the daily newspaper. People who do not read newspapers are sometimes referred to as nonreaders. Early research has shown that nonreaders are generally low in education, low in income, either very young or very old. In addition, nonreaders are more likely to live in rural areas and have less contact with neighbors and friends. Other studies show that nonreaders tend to isolated themselves from the community, are less likely to own a home and seldom belong to local voluntary organizations. Why don't these people read the daily paper? They say they don't have the time; they prefer radio or TV; they have no interest in reading at all. And besides, they think newspapers are too expensive. Recent surveys, however, have indicated that the portrait of the nonreader is more complicated than first thought. There appears to be a group of nonreaders that does not fit the type mentioned above. They are high in income, and fall into the age group of 2665. They axe far more likely to report that they don't have the time to read the papers and they have no interest in the content. Editors and publishers axe attempting to win them back. First, they are adding news briefs and comprehensive indexes. This will help overcome the time problem. And they are also giving variety to newspaper content to help build the readers' interest.

B.They are active in voluntary services.
C.They tend to be low in education and in income.
D.They live in isolated areas.

Since 1939, scientific studies have shown that smoking does great harm to one's health and it will shorten one's life.
Cigarette smoking is believed, by most research workers in the field, a very important cause in the development of the cancer of the lungs and the cancer of the throat and is believed to have much to do with some other kinds of cancers. Cigarette smokers suffer from the illness of the heart more often than those who don't smoke. But strange, yet true, women are thought to be less affected, because when women smoke, they usually don't breathe in the smoke so deeply. Most of doctors and researchers say, "Give up smoking. If you don't smoke--don't start!"
Filters (过滤嘴) are required now to make smoking a bit safer, but they can only reduce, not get rid of, its poison.
But there are still a number of doctors and research workers who are less sure of the effect of cigarette smoking on health. They believe that the cancers of the lungs, the throat and so on may also be caused by air pollution, or chemical poison that is now being used by farmers in large quantities to destroy plant pests and small animals.
______each smoke about 4,195 cigarettes a year.
A.Americans
B.American men
C.American women
D.American aged 18 or more
