我們可以發(fā)現(xiàn)四級考試作文在話題和提綱形式方面的三個突出特點：
一、寫作話題非當(dāng)前社會熱點話題(如：2008年6月前后熱點的社會話題應(yīng)該是奧運會和汶川地震，但四、六級、考研寫作話題均未出現(xiàn));相反，四級考試的話題更多的集中在了次熱點話題上(如：英語學(xué)習(xí)、綠色校園、一次性塑料袋等等均非當(dāng)年大家特別關(guān)心的話題，但是這些話題本身又沒有脫離社會和學(xué)校的范疇)。
二、寫作類型考查以論說文為主(9次)、應(yīng)用文(2次)為輔，其中尤其需要注意的是在論說文的三種類型中，問題解決型是近來考試的熱點(5次)、其次是觀點對比型(3次)和現(xiàn)象描述型(1次)。
三、論說文的首個提綱多考查到現(xiàn)象描述能力，即使應(yīng)用文均考察到了描述或說明類寫作能力。如2007年“俱樂部介紹”的寫作中要求考生對俱樂部進行英文介紹，本質(zhì)上與描述現(xiàn)象寫法無異;2006年6月(老題型)的首個提綱也不例外。
綜合以上分析，筆者認為考生備考階段應(yīng)該重點培養(yǎng)“現(xiàn)象描述”、“原因/問題分析”、“解決措施”和“發(fā)表看法”幾個重點功能段落的寫作能力。
在接下來的幾天里，給出的是幾個課堂練習(xí)實例，請各位同學(xué)參考：

首段：3句話= 背景+事實描述+舉例說明
The past decade has witnessed the huge advancement of Information Technology (背景描述). And shopping through the Internet has gained great popularity among web suffers(主題事實描述).

2段：問題分析4句話 = 主題句+ 危害1+危害2 +危害總結(jié)
In spite of the convenience and low price of this shopping, others argue that we can not turn a blind eye to its negative aspects. Firstly, they point out that the quality may not be as superior as it is described and sometimes, it is possible for customers to buy fake commodities. In addition, many customers find it troublesome to make a change when they are not satisfied. As has been noted, these do exert bad impacts。
尾段：解決措施(即我的看法)3句話 = 總說+建議+展望未來
As a customer, I <img border=0 src=../im2/9076_4.gif alt=www.cet4v.com> effective measures should be taken to enhance it。(總說看法) To be specific, it is suggested that regulations and rules should be worked out to scrutinize online shop owners. (或者：Specifically, shoppers are well-advised to be alert when purchasing online。) A promising online shopping is just awaiting us if we spare no effort to do so。
