Noise is growing and it may get much worse before it gets any better.Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.There is a saying about it being so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems.Noise adds more tension (紧张) to a society that already faces enough stress.But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots (四轮马车) from moving through the streets at night!Ways of making less noise are now being tested.

Task 7Life in the twentieth century demands preparation. Today, all individuals in a country must have adequate schooling to prepare them for their work as well as for their responsibilities as citizens. With this in mind, national leaders everywhere are placing more emphasis on the education of the young.In the United States, government officials, parents, and teachers are working hard to give the children -tomorrow's decision makers -the best preparation available. There is no national school policy in the United States. Each of the fifty states makes its own rules and regulations for its schools, but there are many similarities among the fifty school systems. Public schools in all states are supported by taxes paid by the citizens of the individual state.In most states the children are required to attend school until they reach the age of six. When they become six years old, children begin elementary school. After six years in elementary school, they go into junior high school and remain there for three years. The last three years of their public school education are spent in senior high school, from which they graduate at the age of eighteen.A great number of high school graduates continue their education in one of the many colleges or universities in the country. After four years, they receive a Bachelor's degree. Some continue studying for a Master's degree and perhaps a Doctor' s degree.（分数：5.00）(1).At what age does a child in the United States enter elementary school?（分数：1.00）A.16.B.6. √C.8.D.7.》解析：细节辨别题。
