最后总结一下1 ，看到定语从句先跳过去找主干，找到主干后再把定语加上去，否则定语从句很长, 导致谓语很靠后，很难理清主干。
2 ，关于引导词的省略，that who等等很多引导词都可以省略，而且在长句子里面常常省略，我们有时候写作文也会不知不觉省略，比如说he is the one I fell in love with .. 就省略了that或者who, 一般在限定性定语从句里面，引导词（that who 等）作为从句里面的宾语时往往可以省略，比如上面的这个句子还有the guy you spoke to stole a gun,还有修饰way的时候往往也省略引导词，比如说I don't like the way you speak to your mother.关于省略还是要靠大家多读培养语感，从理论上解释其实很不实用，也不太全面，比如说第三个句子连that带were 一起省略了，而且还不是从句里的宾语是从句里的主语成分。
3 ，有时间的同学还是要多背单词，现在大家可以用字典查，但是考试的时候单词不认识句子结构又复杂肯定就死在这里了一、分析含定语从句的长难句。
