关键词作文是根据作文题目以及所给出的关键词写短文。关键词的数目由几个到十几个不等。写这种题型的作文，要特别注意关键词的作用。关键词是短文内容发展的“路标”，在作文思路和写作内容上起着决定乾坤的作用。因此，写出的文章要把所给的这些关键词都用上，可以一句中用上几个词，也可以几句中用上一个词，只要能做到恰到好处即可。而且，要学会根据所给关键词的语义群分段。如果所给的关键词可以分为三组，那么，短文就可以写成三段。如果给出的关键词是两组，短文就可以写为两段。再者，要把给出的关键词用在刀刃上，即各段的主题句以及结尾的主题句都应该有关键词。

The Advantages of Travel
Whenever a college student is asked“What are you going to do this summer vacation?”the most probable answer might be“I am going to have a trip.”It seems that college students are fond of traveling very much. Why?Because travel has numerous advantages.
First of all,travel can widen our knowledge of geography,the knowledge of different customs, cultures and lifestyles of different places and countries. Secondly, we can make friends and practice a foreign language through traveling. Finally, travel is the best way of spending time. We can enjoy eating various local foods and seeing beautiful scenery.
In a word, we can benefit from travel in more than one way. It is worth spending the time.
作者在第一段中就用上了关键词travel和advantage，并很巧妙地利用Because travel has numerous advantages这样的承上启下的句子来引出下文关于旅游的种种好处。最后又把关键词用在了文章的结尾处，强化了主题，不失为画龙点睛之笔。

The Helpful Features of Textbooks
Textbooks are books that students use in schools. Students at all levels and in all kinds of schools use textbooks. They have certain features in common—features that can help students find and understand the information in them.
All textbooks have tables of contents at the beginning. The tables of contents list the chapter titles, the parts of the chapters,and the page numbers of the parts. These sections are divided again into smaller parts with headings and subheadings. Finally, most textbooks have an index at the back of the book. The index lists all the topics in the book in alphabetical order, and gives their page numbers.
These are the features of most textbooks, which help students find and understand the information in textbooks quickly and efficiently.
文章一开头用定义法给教材下了个定义。接下来具体说明教材的主要特征。最后一段与第一段相呼应，并重复和强调了几个关键词中的关键词，比如textbooks，information等。 |
