注意：当感官动词与使役动词用于被动时，需恢复to的省略。如：The girl was seen to cross the street.

（此句中，前一个分句带一个As引导的状语从句，状语从句中 move away from 后为并列平行结构，their…，their…，their…在and后的分句中，the confidence后省略了is cut off.）
3.复合句的省略
a) 复合句中从句的句尾和主句相重复时从句的句尾部分可省掉
Mary is going to sweep the floor because Alice won't (sweep the floor).
b) 含有定语从句的复合句
①定语从句中可以省略作宾语的关系代词；非正式文体中，也可省略关系副词when或why.

He can't go to school, but I don't know why (he can't go to school).
d) 含有状语从句的复合句
状语从句中的省略原则是，如主语与主句主语一致，或主语是it，可省略从句的连接词、主语和be助动词，只保留分词和其它成分，从而使语言更加简洁明了。
