1. 請描述我國吸毒者年齡分布情況

　　2. 請說明發(fā)生這些變化的原因

　　3. 這一變化對社會和個人的影響

　　As can be seen from the graph, there have been sharp changes in the age distribution of drug addicts. To be concrete, the teenage addicts only made up 10 percent of all the drugsters in 1982 while the ratio rose up to 65 in 2002.

　　The causes for them are not hard to find. First , teenagers’ fearless curiosity about everything new has led some of them into this marsh. Second, many of the young addicts turned for the first time to drugs for escape either from their failure in the national entrance exams or from their parents’ breakup. And above all, our education in the harmfulness of drugs has been far from adequate to build teenagers’ sound resistance to drugs. To sum up, the causes mentioned above must call for more of our concern, and effective measures should be taken to check the trend.

　　Obviously the drastic change will exert great impact on individuals and the whole society. For one thing, drug-taking does great damage to the health of drug users.. For another, some drug users commit robbery or even murder their parents and relatives to get money to buy drugs, which poses a great threat to the social security and the socialstability. Therefore, it is high time we did something to put an end to this trend.

　　Social Practice

　　Social practice has been more and more popular in universities and colleges. Students are asked to enter society and get some idea of it. Surely social practice has many advantages. Firstly, social practice can offer students a chance to contact society and meet different kinds of people. In this way students can gain some valuable socialexperience, which will be useful to their future career. Secondly, students can apply what they have learned in class to practical work, thus knowing themselves more clearly. Thirdly, social practice can bring them some financial reward and make them more independent of their family.

　　However, some problems may arise if no correct guidance is made. For example, some students get overly interested in social practice and want to work full-time and earn money, thus neglecting their studies. And some students are likely to get in touch with the dark side of society, which will affect their future studies.

　　In order to carry out social practice smoothly, students should first know its objective. They should put their studies in the first place and see social practice just as a useful supplement, so they ought to try to strike a balance between social practice and their studies.
