b) 含有定語從句的復合句

②關系代詞as后面的主謂結構也可省略

①在兩個并列的that從句如主動詞及其賓語、表語、狀語等都一樣時可將第二個that從句的主動詞及隨帶成份省略。

I guess Lisa will dance in the party but Jane won't (dance in the party).

W's English

②在兩個并列的that從句如主語相同，而謂語不同，可把第二個that從句的連詞和主語一起省略。

③在兩個并列從句如連詞不同而其它成份相同時，可省略第一分句和第二分句相同的部分，只把兩個連詞連接起來。

I was very pleased my friend had passed the exam.

d) 含有狀語從句的復合句

狀語從句中的省略原則是，如主語與主句主語一致，或主語是it，可省略從句的連接詞、主語和be助動詞，只保留分詞和其它成分，從而使語言更加簡潔明了。

⑧狀語從句中并列結構的省略

在復合句中，如兩個并列的狀語從句只是從屬連詞不同，其它相同時，則可省略一個狀語從句，而把兩個從屬連詞連接起來。

虛擬語氣條件句中if的省略

與If引導的條件從句中含有were, had時，可將if省略，并用倒裝結構。
