长难句增加,是近年高考阅读理解试题不可忽视的现象之一。英语的长句可分为两类:含有数量较多的定语或状语的简单句和含有数量较多的各种从句的并列句或复合句。阅读长句的基本方法是抓主干,理枝叶。抓主干就是抓句子的主体部分,也就是主语和谓语,它们是传达信息的主要载体;理枝叶就是分析句子的附加部分,不论它们有多长,有多复杂,它们都是辅助成分,我们只要明确它们与主体的关系就可以了。如:
The moon is so far from the earth that even if huge trees were growing on the mountains, and elephants were walking about, we could not see them through the most powerful telescopes which have ever been invented.
这个长句的主干就是The moon is far from the earth,其他部分,如状语从句、定语从句等,都是为突出主题服务的。
