说明文

　　说明文就是用简单的文字说明事物的特点、类别、构造、用途、成因等。它包括广告、知识小品、教材、书文简介、理论性概念或定律的解释。

　　写说明文应清楚以下几点：

　　1、条理分明，遵循空间顺序、时间顺序、逻辑顺序、因果关系。

　　2、说明文要浅显、准确、简介，避免过分的夸张。

　　例文一：以“how to protect your eyes”为题写一篇130字左右的文章。

　　how to protect your eyes

　　“eyes are windows of the soul,” people often say. everyone understands how important the eyes are. but how to protect eyesight remains a question among us students, at least many of us. if you want to protect your eyesight, you must pay attention to the following points:

　　first, you should not keep your eyes working for a long time. after you have studied for a ling time, about an hour or so, you had better have a rest by looking in the long distance.

　　secondly, you should keep your book about a foot away from your eyes when you read it. you should also keep in mind, “don’t read in a poor light or in the sun; don’t read in the moving bus or in bed.” doing eye-exercises will help you keep good eyesight.

　　if you fail to keep these rules, you will become short-sighted sooner or later.

　　例文二：

　　你到杭州游览，报上介绍三家酒店，情况如下：

　　酒店a，四星级，位于火车站旁，房间和各种设施条件良好。

　　酒店b，四星级，位于著名的西湖旁，景致极好。

　　酒店c，二星级，位于离开西湖仅5分钟步行路程的一条小马路上。

　　你会选择哪家，请说出你的理由。

　　i will choose the two-star-hotel near the west lake.

　　first, i am a student. i can’t afford my own living now. so there is no need to waste money to choose a four-star hotel. it is a waste of money.

　　second, this hotel is quite near to the west lake. it only takes me five minutes’ walk. so i don’t need to pay for taxies or buses. it is very convenient for me to visit the west lake anytime i want.

　　and with all the money i have saved, i can enjoy a more exciting visit to the west lake. i can visit more places, play more games and also enjoy more good food.

　　though the hotel is not as beautiful as the other two hotels, and its services may not be as good as those two hotels, i will still choose this hotel because i think i can enjoy my several days’ trip here.

　　总之，英文写作是一个学生英语综合能力的书面体现，它需要一个长期复杂的训练过程。但是如果教师让学生在了解掌握写作技巧和模式的基础上，同时在平时不断从学生的实际水平出发，有目的、有计划、有要求、有检查、有反馈地培养学生的写作能力，由易到难，循序渐进，那么学生到写的时候就能做到厚积薄发、思如泉涌、下笔如有神。
