根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    Anyone who has ever tried to stop smoking knows how difficult it is to quit. There is no lack of information about how unhealthy smoking is for you- not to mention the unpleasant smell. So why would teens ever begin to smoke?

    ____ Research shows that the majority of smokers lit up their first cigarette in their early or mid-teens, precisely at a time when children are beginning to establish their own identity apart from their parents. Smoking can be an act of rebellion(反抗) against parents or authority figures, as well as a way to fit in with others and feel accepted.

    Here are some things that parents can do to help a child stay smoke-free.

    Start talking to your teen about how bad smoking is for him early, well before his teens. Keep talking, too. ____

    ____ For example, smoking makes your hair and clothing smell bad, stains the teeth, and reduces your lung power to play sports.

    ____ Talk about the addictive power of smoking and tell him while those few cigarettes are his choice, the addiction that occurs shortly afterwards makes him powerless to decide whether or not he wants to light up.

    Work on self-esteem(自尊) and self-confident with your teen. Much of the attraction of smoking is to gain acceptance. ____

A.Young teens live in the moment, too.

B.Play on your child's desire to make his own choices.

C.The answer lies in the develop-mental stage of your teens.

D.Give your child the facts, but focus on the things he can relate to.

E.Help your teen to feel good about himself without having to smoke.

F.One discussion will not be enough to help your child not to smoke.

G.They won't be aware of how powerful addictive smoking is in a very short time.
