Few people like changing their habits, good or bad. Whether it is smoking, drinking or over-eating, they       “enjoying” them to the end.
On every packet of cigarettes(香烟), people are warned against the       of smoking: “Warning: Cigarette Smoking Is Dangerous to Your Health”.      , millions of them start smoking or go on smoking. Why?
Facts show that families and surroundings(环境) play a very important part in       smokers. All those smokers come from smoking families or have smoking       or relatives. Films and TV plays also play a part. People       their “heroes” on TV drinking alcohol(酒) or smoking cigarettes. “Heroes” seem to fear      , neither killing themselves nor killing others with alcohol and cigarettes. If they are not afraid of the harm of smoking and drinking,       should common people be afraid?
The simple warning on the cigarette packet does not influence smokers’ habits. Even       warnings, like showing pictures of smokers who have died of cancer, don’t seem to work.
Knowing and believing seem to be two       things. If smoking is really as harmful as doctors say, it is time for smokers to think about it and try to give it up!
