六、條件狀語從句。

條件狀語從句是表示主句動作發(fā)生的前提或條件的從句。條件狀語從句分為真實(shí)條件狀語從句和非真實(shí)條件狀語從句（見第3章）。引導(dǎo)條件狀語從句的有if, unless, so as long as, as so far as, on condition that, in case, suppose, supposing等。條件狀語從句中的謂語動詞一般要用現(xiàn)在時(shí)或過去時(shí)代替一般將來時(shí)或過去將來時(shí)。

 a.if if表示正面條件，意為如果。
 if you ask hm, he will help you.

 difficulties are nothing if we are not afraid of them.
 如果我們不怕困難，困難就算不了什么了。
 if i do not understand what he says, i always ask him.
 我不懂他的話時(shí), 總是去問他。（if = when）
 比較：
 if only和only if的對比。
 if only 解釋但愿，要是��就好了，表示一個(gè)不可能實(shí)現(xiàn)愿望，要用虛擬語氣。
