Question

A recent survey showed that only 9percent of teens in the United States smoke cigarettes．That's down from 23percent in 2000．While this is good news for the US's overall health，tobacco（烟草） use is still a problem．
Cigarettes can cause many diseases，such as cancer（癌症），lung diseases and heart problems．Although they know about the health problems，teenagers still smoke．So the campaign of the US Anti-smoking Organization is working to end teenage smoking．Their latest activity uses social media（社交媒体） to remind teenagers of the dangers of smoking．And the activity also encourages teens to learn the facts and become the generation that ends smoking．
