第三节关键词作文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 TravelWhenever 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。
