英语书面表达在高考试卷中占有较大的比重，然而，不少考生只是使用较简单的词汇和句式来写书面表达，因而得分不高。高考书面表达评分标准提倡考生使用较多的语法结构和词汇，所以高级句型的使用成为高中英语教师和考生普遍关心的问题。那么，如何在作文中使用高级句型呢？
其实，我们可以把平时使用的简单词汇和句式稍加改变，就可以使句式更丰满，表达更有力，从而增强文章的表达效果。
1. 使用高级词语
随着学生英语学习的深入，他们学到了一些较高级的词汇和短语。这些词语可以替换他们原来使用的词语，因而使句子表达更地道，更达意。例如：
1）He spends all his spare time in reading. 用spend替换devote→
He devotes all his spare time to reading.
2）On his way to school, he found an old lady sitting by the road, looking worried. 用seat 替换sit→
On his way to school, he found an old lady seated by the road, looking worried.
3）I'm very glad to learn that you are coming in September. 用more than 替换very→
I'm more than glad to learn that you are coming in September.
4）After walking 10 miles, we all felt tired. 用cover替换walk→
After covering 10 miles, we all felt tired.
5）The summer vacation is coming soon. Do you have any plans? 用 round the corner 替换come soon→
The summer vacation is round the corner. Do you have any plans?
6）The products are very good and are sold everywhere in China. 用“be of 名词”替换“be 形容词”→
The products are of high quality and are sold everywhere in China.
2. 使用高级句式结构
除了一些高级词语的使用，英语中还有一些特定的句式结构，比如，强调句型、倒装句、从句等等，学生若能够在书面表达中准确、恰当地使用，就一定能为书面表达增加亮点，使句式变新颖，语气变强烈，从而提高书面表达的档次。
