連詞有：as, as if/ as though

(1) as引導(dǎo)的方式狀語(yǔ)從句, 意為"以……方式;如同……那樣"，從句有時(shí)是省略句。如：

Do as I say. 要照我說(shuō)的做。

I did just as you told me. 我正是照你說(shuō)的辦的。

Air is to man as water is to fish. 空氣之于人猶如水之于魚(yú)。

(2) as if/as though引導(dǎo)的方式狀語(yǔ)從句

as if和as though的用法相同，都作"好像，仿佛"解。如：

二者引導(dǎo)的狀語(yǔ)從句往往用虛擬語(yǔ)氣，表示與事實(shí)相反。as if比as though更為常用。但也可用陳述語(yǔ)氣，表示所說(shuō)的情況是事實(shí)或?qū)崿F(xiàn)的可能性較大。如：

They looked at me as if , as though I were mad.

他們瞧著我好像我發(fā)瘋了似的。

They look as if/as though they know each other.

他們看來(lái)好像互相認(rèn)識(shí)。
