smoke作名词时是"烟,烟尘,烟幕"的意思,作动词是"吸烟".
而smoking可以说成名词形式或者是动名词.
比如.No smoking!就是禁止吸烟的意思.
smoking是动名词，在这个句子里做主语，而smok只是动词，在句子中不能做主语的。所以it says smoking is bad for you healht中的smoking不用smok。
smoke是侧重于烟的意思
这里强调吸烟这一动作，用smoke的动名词形式
先纠正句中两处错误，是“your health”，而不是“you heathl”！smoke是动词，不能作主语，而名词可作主语，smoking是smoke的动名词形式，故可作主语使用。
smoking是动名词，因为smoke是动词不能用在这里
