二、寫作實(shí)例分析

　　(一)說(shuō)明文(1)

　　說(shuō)明文一般用于解釋和分析社會(huì)現(xiàn)象或社會(huì)問(wèn)題。要求考生對(duì)某種社會(huì)現(xiàn)象產(chǎn)生的原因及其可能造成的種種影響或應(yīng)采取的措施進(jìn)行分析和說(shuō)明。此類文章的基本結(jié)構(gòu)如下：

　　Paragraph 1 phenomenon (現(xiàn)象)

　　Paragraph 2reasons (effects)(原因或危害)

　　Paragraph 3suggestions or solutions (措施)

　　Drug abuse among young people has become more and more prevalent over recent years. (主題句)Statistics show that the number of youth drug users almost doubles in the past three years.(數(shù)據(jù)支撐) It is vital to analyze why drugs are so attractive to young people and what can be done to combat it.(結(jié)論)

　　Firstly, teenagers are under increasing pressure - this may be peer pressure or pressure to succeed for example. Drug use may help them escape reality, forget their problems, or simply feel more accepted by their friends.(原因1) In addition, through the media we are exposed to information that glamorizes drug use and makes it look attractive, particularly to young people.(原因2) Furthermore, teenagers are usually naturally curious about drugs, and drug dealers can take advantage of this curiosity for their own profit.(原因3)

　　High fines and prison sentences should also be imposed on drug dealers and users. (措施1) However, it is my own personal view that prevention is better than cure and so a good education programmed about the dangers of drug abuse is one of the most important steps any government should take. (措施2)

　　(二)說(shuō)明文(2)

　　比較性說(shuō)明文用于比較兩種或幾種類似的事物，要求考生通過(guò)比較它們各自的優(yōu)點(diǎn)或缺點(diǎn)，說(shuō)明自己的看法，并加以論證。這種文章的基本結(jié)構(gòu)如下：

　　Paragraph 1 phenomenon(現(xiàn)象)

　　Paragraph 2advantages (優(yōu)點(diǎn))

　　Paragraph 3disadvantages (缺點(diǎn))

　　Paragraph 4comments(結(jié)論)

　　A mobile phone is getting increasingly popular.(主題句) Statistics show that eight out of ten college students have got one.(數(shù)據(jù)支撐) However, as is the case with many issues, a mobile phone has both positive and negative aspects. (承上啟下)

　　On the positive side, a mobile phone allows calls to be made instantly from almost any location. This can be vital where emergency services need to be called to the scene of a crime, accident or fire, where no public telephone is nearby. (優(yōu)點(diǎn)1) Meanwhile, a mobile phone can serve as a connection to the Internet, which can be extremely convenient for obtaining information wherever you may be. (優(yōu)點(diǎn)2)

　　The fact that a mobile phone allows a person to be contacted at any time can in itself be a disadvantage. For instance, an employee may, via the mobile phone, be constantly available to his employer and feels that he never leaves work. This may cause distress. (缺點(diǎn)1) Another disadvantage is the perceived health risks associated with its use. Some people believe that using mobile phones for long periods can damage the brain. (缺點(diǎn)2)

　　There is no denying that a mobile phone has both benefits and drawbacks but on balance perhaps the advantages of a mobile phone outweigh its disadvantages since a mobile has become an integral part of modern life. (結(jié)論)
