初中英语语法—-—状语从句小结状语从句是一种作状语用的从句,修饰主句的动词、形容词、副词或修饰全句,补充说明时间、地点、原因、条件、方式、程度、状态等。
根据它表达的意思的不同,可分为时间状语从句、地点状语从句、原因状语从句、条件状语从句、比较状语从句、目的状语从句、结果状语从句等.时间状语从句、条件状语从句、结果状语从句、原因状语从句都是中考的重点。
一、时间状语从句时间状语从句表示主句动作发生的时间,引导时间状语从句的连词有when,as, while, before, after,as soon as,till,until,since等。
until 用于肯定句中,表示句子的动作一直持续到until短语所表示的时间为止,即表示动作的终点。
一般可译为“直到……时(为止)”或“在……以前”。
在这种用法中,句子的谓语动词必须是持续动词(非瞬间动词),如live,wait,last, love,like,stay, work, continue等。
until 用于否定句中,表示句子的动作直到until短语所表示的时间才开始发生,即表示动作的起点。
一般译为“直到……才”或“直到……之前(……还不)”eg. It may last until Friday。
这可能要延续到星期五.用于否定句中:eg。
The secret was never told until after the old man’s death.这个秘密在老人去世后才说出来。
连词until以同样的方式分析作连词的until的用法。
作连词用的until的英文释义是up to the time when(直到……时为止)。
作连词的until用于肯定句中,表示主句的动作一直持续到从句动作发生或状态出现时为止。
一般可译为“……直到……为止”。
在这种用法中,主句的谓语动词必须是持续动词(非瞬间动词),如live, wait , last, love, like,stay, work, continue 等。
