听力原文： Childhood poverty has both immediate and lasting negative effects. Children in low-in come families fare more poorly than children in more affluent families in the areas of economic security, health, and education. Children living in families that are poor are more likely than children living in other families to have difficulty in school, to become teen parents, and, as adults, to earn less and be unemployed more. The child poverty rate provides important information about the percentage of U. S. children whose current life circum stances are hard and whose futures are potentially limited as a result of their family's low income.
The full distribution of the income of children's families is important, not just the percentage in poverty. Knowing that more and more children live in affluent families tells us that a growing proportion of America's children enjoy economic well-being. The growing gap between rich and poor children suggests that poor children may experience more relative deprivation even if the percentage of poor children is holding steady.
Since 1980, the percentage of children living in families with medium income has fallen from 41% to 34% in 1996, while the percentage of children living in families with high in come and the percentage of children in extreme poverty have risen, from 17% to 24% and from 70/00 to 8%, respectively.

听力原文： Americans often say that there are only two things a person can be sure of in life: death and taxes. Americans do not have a corner on the "death" market, but many people feel that the United States leads the world with the worst taxes. Taxes consist of the money which people pay to support their government. There are generally three levels of government in the United States: federal, state, and city; therefore, there are three types of taxes. Salaried people who earn more than a few thousand dollars must pay a certain percentage of their salaries to the federal government. The federal government has a graduated income tax; that is, the percentage of the tax increases as a person's income increases. With the high cost of taxes, people are not very happy on April 15, when the federal taxes are due.
(30)
A．Government and taxes.
B．Work and taxes.
C．Freedom and taxes.
D．Death and taxes.

听力原文： The use of illegal drugs by U.S. teenagers has increased in the past two years, according to the latest survey by University of Michigan researchers. The increase reverses a downward trend in drug use among teenagers that began in the late 1970s.
Results of a survey of 50,000 eighth, tenth and twelfth graders throughout the United States indicated a sharp rise in the use of drugs. The researchers also noted an increase in the percentage of students who smoke cigarettes, a drop in the percentage of students who drink alcohol, and no change in cocaine use, which remained at a low level.
Although the general rise in the use of drugs is disturbing, the numbers are still far below the recorded high level of drug use in the 1970s.
A consistent drop in drug use, such as the one that occurred be- fore the recent rise, can't be taken for granted, because each generation of American youth has almost no knowledge of drugs and has to learn the same hard lessons.
(26)
A．A slight drop in the use of cocaine.
B．A drop in the use of cigarettes.
C．A sharp rise in the use of drugs.
D．A rise in the use of alcohol.

听力原文： Some of America's best universities have accepted an unusually low percentage of students for admission this fall (32) . For example, the Wall Street Journal reported that Stanford University had a record low admission rate this year. The newspaper said the California school accepted less than 11 percent of the students who applied.
College admissions officers give a number of reasons for the higher rates of rejection letters this year. They say the main reason is that high school seniors are applying to more schools than in the past (33) . Some colleges reported big increases in the number of applications. Another reason is the general increase in students going to college. Electronic forms make applying easier. For example, students can send an online form. called the Common Application to many different colleges and universities. Many students who apply to top schools are placed on a waiting list. They do not get a decision until the school knows how many applicants who are offered admission will accept the offer (34) . Just as students compete, so do schools.
The increasing competition for the best colleges means more worry for students and parents. They wander just what schools are looking for. They wonder why a top student is accepted at one school but not another (35) . The Wall Street Journal says some top schools are actively looking for students who have shown great interest in helping others. Other schools are said to be looking for students who have musical talent.
(33)
A．The best universities in the United States.
B．High school students' choices after graduation.
C．Electronic application in college admission.
D．The increasing competition for the top schools in the U. S.
