     Every day after school millions of children-most of them in middle school or high school-head home to

empty houses. Often, they're on their own until dinnertime or later-not by choice, but by necessity. While

they may be old enough to avoid setting the house on fire, each afternoon is still a minefield (充满隐伏危险

的事物).

     It's a minefield hidden with drugs and alcohol, Internet addiction, violent video games and,perhaps worst

of all, loneliness.

     But families have little choice. With more parents working full-time than ever before, it's no surprise that

the number of so-called latchkey kids in the United States is also at an all-time (空前的, 创纪录的) high. Up

to 15 million of the country's 49 million school-age children spend part of the workweek on their own; almost

a third do so at least three days a week.

     The afternoon hours are also dangerous when it comes to crime. The U.S. Department of Justice reports

that the rate of violent crimes reaches its highest point between 3 p.m. and 4 p.m.-nearly the same time at

which children are most likely to be victims of such crimes. One study found that those who are on their own

11 hours or more a week are twice as likely as those who aren't to drink or smoke.

     All this leads some health experts to an important conclusion. "Lack of adult involvement is one of the

strongest influences on bad behavior," says Robert Blum,chairman of population and family health at Johns

Hopkins School of Public Health in Baltimore. In fact, he and others believe it's stronger than background,

family income, or family structure. "And the more time teens spend unsupervised (无人监督的), the worse

they'll behave."

     Blum and others believe teachers can help by transforming their schools into more nurturing environments.

He also argues for more and better after-school programs. But the final responsibility lies with parents. One

survey found that almost 90％of students agree that, "Even though I might complain about it, sometimes I

need to be pushed by my parents to do things that are good for me."

1. The passage is written to _____.

A. teach parents how to have good relationship with their kids

B. warn teenagers to stay away from drugs and alcohol

C. remind parents to pay more attention to teenagers who spend time alone at home

D. express the hope that kids should spend more time studying after school

2. The underlined words "latchkey kids" in paragraph 3 probably mean _____.

A. children who are at home alone after school

B. children who are addicted to video games

C. children who are in charge of the house key

D. children who spend more time online than at school

3. What is the main reason for bad behavior in children, according to the passage?

A. Violence

B. Lack of supervision

C. The Internet addiction

D. Drugs

4. Which of the following is NOT a good way to prevent children from behaving badly?

A. Having children spend more time with adults.

B. Having more and better after-school programs.

C. Having more supervision from parents.

D. Having children chat more with their friends.

Product Description
In the 150 years since the publication of Origin of Species, Charles Darwin has been considered between two extremes--- a great biologist or heretic（持异端学说者）. However, the truth is much more difficult to understand than that. In any case, Darwin’s theory of evolution and natural selection had the greatest influence in history.
In The Darwin Myth，author Benjamin Wiker offers a full-side analysis of Darwin’s theories as well as the social, scientific, and religious effect of his work. Scientists often cause debates(争论) that will last for generations for their new theory. Still, no scientist has caused more debates than Charles Darwin. To some he is the revolutionary “father” of evolution. To others his theory of evolution unconsciously disagrees with many ideas in modern eugenics.（优生学） In The Darwin Myth: The Life and Lies of Charles Darwin, author Benjamin Wiker will make them clear.
