6：名詞性從句
在句子中起名詞作用的句子叫名詞性從句，它包括主語從句、賓語從句、表語從句和同位語從句。

7：定詞性從句
定語從句(Attributive Clauses)在從句中作定語，修飾一個名詞、名詞詞組或代詞，被修飾的名詞、詞組或代詞即為先行詞。定語從句通常出現(xiàn)在先行詞之后，由關系詞(關系代詞或關系副詞)引出。

8：狀語從句
狀語從句在復合句中作狀語。根據(jù)句子的含義，它可表示時間、地點、原因、目的、結果、條件、行為方式、比較、讓步等。
狀語從句一般由連詞(從屬連詞)引導，也可以由詞組引起。從句位于句首或句中時通常用逗號與主句隔開，位于句尾時可以不用逗號隔開。
狀語從句的構成：
引導詞+狀語從句+“,”+主句：When she came in, I stopped eating.
主句+引導詞+狀語從句：We were about to leave when he came in.
狀語從句的關鍵是掌握不同狀語從句的常用連接詞和一些特殊的連接詞。
