方式狀語從句的基礎(chǔ)知識

方式狀語從句是描述動作方式的從句。方式狀語從句常由as, as if as though等詞引導(dǎo)，通常位于主句之。

方式狀語從句的用法

A. as, just as

這兩個連詞的意思是如……，正如……一樣。just as 比as 語氣要強(qiáng)一些。

入鄉(xiāng)隨俗。

Please do as you are told.

請按照人家告訴你做的去做。(也可說Please do as told.)

注意：

在口語中，還可用like來代替as，引導(dǎo)一個方式狀語從句。

B.as if, as though

由as if 或as though引導(dǎo)的狀語從句可以用陳述語氣表示可能符合事實的情況，也可以用虛擬語氣的過去式表示現(xiàn)在不符的或與事實相反的情況(見第3章虛擬語氣)。
