People put in plastic bags everything they buy. They no longer need to prepare bags for shopping. Obviously it is very convenient in people’s everyday life. However, plastic bags have terrible effects. Large amounts of plastics are thrown away as trash every day, which cause a great harm to our environment . They let out poisonous substance and deteriorate the soil. What’s worse, they can not disappear by natural deposition. This is called the “white pollution”. Individuals, supermarkets and panies are all responsible for the white pollution. A suggestion is made to levy tax on plastic bags in order to limit people’s use of them.

What impresses us most is that, in 2000, college students averagely spent 20 hours per week on puter, which is more ten times than the size ten years ago. There are many reasons accounting for this phenomenon.(描述現(xiàn)象段)First of all, the decreasing price of PC plays an important part .What’s more, Internet provides students an amazing world to explore. For example, people can make friends around the world. In addition, for students, the puter can be a great help to their study. Therefore, more and more students devote their time to puters.（說明原因段）As far as I am concerned, there are some problems existing in student use of puters. On one hand, lack of skills fails students to make full use of the puter. On the other hand, lacking necessary disciplines, some students indulge in puter games and net world, forgetting their major tasks as college students. In brief, I may reasonably conclude that there is still a lot to do to help students make good use of puters.（觀點總結(jié)段）模板練習Direction: For this part, you are allowed thirty minutes to write a position on the topic How People Spent Their Holiday.

This significant growth in the use of puters by students in the 1990s can be attributed to several factors. Firstly, because of the social modernization, puter bees an indispensable tool for students to study and municate. Today’s society relies heavily on puters for immediate access to the news and for entertainment. Secondly, the fast development of the internet stimulates people to spend more and more hours on puter. What’s more, due to the fierce petition in Hitech industry, the price of puter has dropped significantly. It is no longer a luxury but a mon “household appliance”. However, the increasing use of puters results in some problems and challenges. Some students cannot resist the temptation of some unhealthy information on the internet and are lured by it without selfcontrol. And some others indulge themselves in puter games so much that they cut class so often.評析：相對于統(tǒng)計表來說，柱形圖的數(shù)據(jù)顯得非常簡潔明了。四級作文復(fù)習總結(jié)性材料四級作文的類型類型主線組織材料形式現(xiàn)象解釋型現(xiàn)象存在的合理性描述現(xiàn)象闡述原因表明觀點對比選擇型比較兩種不同觀點分析觀點作出選擇問題解決型兼顧問題各方面，解決問題提出問題—分析問題的原因或危害—解決問題觀點論證型證明觀點的正確性表明觀點—論證觀點—得出結(jié)論應(yīng)用文所給情景中的要點描述事實—闡述原因—表明觀點或提出建議◆模板僅供參考，大家需靈活運用（ 材料中某些范文沒有采納材料中完全照搬的模板，但結(jié)構(gòu)和組織是相似的，只是語言選擇的不同，請大家學(xué)習借鑒。）常用句式：1．As we can see from the chart/graph/table/diagram,…2.
