    According to a survey, more than two fifths of the students smoke in a school. They often get extra money from their parents to pay for cigarette, but their parents usually do not realize it. Even, some students steal money to buy cigarette, which is really a serious event. For middle school students, smoking do more harm to them than to adults, which is not only harmful to the body, but also detrimental to thinking. Furthermore, smoking is also harmful to others. Experts say that the second-hand smoke do more harm to others than the smoker.

    現(xiàn)在，許多學校學生吸煙，而且數(shù)量也越來越大，這使得學校和家長們都很擔心。
    據(jù)一項調(diào)查顯示，超過五分之二的學生在學校吸煙。他們經(jīng)常從父母那得到額外的錢來支付香煙，但他們的父母通常都沒有意識到它。甚至，一些學生偷錢買煙，這真是一個嚴重的事件。對于中學生，吸煙對他們的危害比成年人多，這不僅對身體有害，而且對思想有害。此外，吸煙也對他人有害。專家說，二手煙對他人造成的危害比吸煙者多。
    總之，吸煙是一種不好的習慣，它浪費金錢，也危害健康。
