（二）说明原因型议论文

1．说明原因型议论文结构模式

描述现状（问题）→分析原因→结论（我的建议、看法、号召）

2．说明原因型议论文写作要领

这类考题的核心部分就是说明原因。考生首先要说明与题目相关的现状，然后通过列举或举例等写作手法，将该现状形成的原因讲清楚。最后，提出建议或总结观点，这样，一篇佳作便产生了。

另外，考生在提出建议或看法时，注意和前一段中问题产生的原因相呼应，这样整篇文章才会显得结构紧凑，有理有据。另外，在列举数个原因或建议时，切记杂乱无章。可以使用firstly, secondly, furthermore, finally等连接词来保证整段文章的连贯性和条理性。

范文（I）

Directions: In this part, you are allowed 40 minutes to write a composition of 120－150 words on the topic of Advertisement on TV. Your composition should be based on the following outline given in English and should start with the given opening sentence: “Today more and more advertisements are seen on the TV screen.”

1）Present state

2）Reasons

3）My comments

Today more and more advertisements are seen on the TV screen. Every evening a series of advertisements come after TV programs, informing TV viewers of various up-to-date products on the market.

Why are there so many advertisements on TV? The first reason is that both manufacturers and sellers want to beat the drum for their products and make their brands well-known through advertisement. Only after the products are widely known, can they be accepted by people. Besides, potential customers would like to be informed of the goods on sale. TV advertisement offers a convenient way for people to know what are at a discount. The third reason is that TV stations need the fee charged for advertisements to support other programs.

Everything has its own two sides, no exception with the TV advertisement. For one thing, it provides us with commodity information. What’s more, some advertisements for public welfare draw people’s attention to some social problems. For another, the advertisements always interrupt an integrated movie or play, which is really something troublesome. But you can choose not to watch them as you like.
