1．结构分析法
所谓结构分析法，就是通过语法分析，迅速弄清句子的结构，把握住句子的基本框架。基本步骤是：首先，判断该句是简单句、并列句还是复合句；然后，找出句子的核心成分，分清主语和谓语；最后，再分清句子的附属成分。
方法一：较复杂单句的处理方法——找主谓语，即找主干成分
较复杂单句在高考试卷中经常出现，所以应引起考生的足够重视。
①However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last past about 120 years.
[分析] 此句的主语为“many scientists”，主语后跟一个由who引导的定语从句。主句有两个谓语，即 are doubtful和say，say后面又接了一个宾语从句。
②Some companies have made the manufacturing of clean and safe products their main selling point and emphasize it in their advertising.
[分析] 此句的主语为“Some companies”，句中有两个谓语，即 have made和 emphasize。
③ At the press of a button, microcomputer locks all other floors chute (道) doors and sets the recycling container turning until the right box comes under the chute.
[分析] 此句的主语为“ a microcomputer”，也有两个谓语，即 locks和sets。
方法二：并列复合句的处理方法——找并列连词
①The hot sun had caused the dough (面) to double in size and fermenting yeast made the surface shake and sigh as though it was breathing.
②Miss Germaine's mother looked anxious through the wedding and Mr. Cordell's parents are reported to be less than delighted.
[分析] 第①句中的and和第②句中的and都是并列连词，各自连接两个并列单句。
