Speaking from my past experience, it is very difficult to find good friends that you can trust but once you have found them, they are worth keeping forever! Therefore, I think friendship is the most important relationship that anybody could have.

The qualities I look for in a friend are a good sense of humor but sensitivity when it matters. Also that friend would have to be strong-minded and highly spirited. I think that these qualities are the key qualities to look for in a good friend.

Even the strongest friends can still have arguments, although usually about more serious topics, rather than the usual teenage childish arguments. Some matters can seriously affect a friendship. If one of your friends started experimenting with harmful and dangerous drugs, what would you do ? A good friend would try to help as much as possible, whereas a bad example of a friend would simply shrug(耸肩) and turn a blind eye.

Not only the bad things affect friendship ---- good activities do too. Such as bonding with one another, not just by going out on a night with them but by spending quality time with them and talking to each other, which indicates a good ability to communicate. This is a key aspect of a good friendship.

Good friends do not always have to be in the same age group as you. I have a good friend and she is 47 years old and I am 16.

Unfortunately, some people lose contact with their friends as they grow older, which is a sad way to lose a good friend.

I think friendship is one of the most important things in life because if you have no friends you will have no happiness.

Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths due to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death.

Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised.

First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors beat that among female by nearly 10 percent . The statistic is reversing (完全相反的). Third, several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .

Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking level among youth.

A. traffic accidents B. smoking-related disease

4.The reason for declining adolescent smoking is that ________.

A. NCI has taken effective measures

B. smoking is prevented among high school seniors
