【—語法對(duì)讓步狀語從句的總結(jié)】下文是通過對(duì)條件狀語從句概念的整合,還有例題對(duì)條件狀語從句的具體分析。
條件狀語從句
連接詞主要有 if, unless, as/so long as, on condition that 等。.
if 引導(dǎo)的條件句有真實(shí)條件句和非真實(shí)條件句兩種。非真實(shí)條件句已在虛擬語氣中闡述。
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
典型例題
You will be late ___ you leave immediately.
A. unless B. until C. if D. or
答案A。 句意:除非你立即走,否則你就回遲到的?赊D(zhuǎn)化為 If you dong leave immediately, you will be late. B、D句意不對(duì),or表轉(zhuǎn)折,句子如為 You leave immediately or you will be late.
對(duì)上述對(duì)條件狀語從句的概念及什么是條件狀語從句掌握,如果又不懂的可以參考。
