高中英语语法状语从句精讲在复合句中修饰主句或主句中的某一成分的从句叫状语从句。
状语从句通常由附属连词或起连词作用的词组引导,有时甚至不需求连词直接和主句衔接起来。
状语从句依据它表达的意思不同,可分为时间、地点、缘由、目的、结果、条件、方式、比拟、退让等九类。
一、时间状语从句时间状语从句是表示时间关系的从句。
可以引导时间状语从句的连词很多,依据意义和主从句之间的时间关系,通常可分为以下几种状况:A.when, while, as, wheneverwhen, while, as表示主句谓语作和从句的谓语举措同时发作或简直同时发作。

②while有时可以作并列连词,表示对比,可译成……而……。

③while有时可引导退让状语从句,意思是虽然。

提示:虽然during 与while 意思很相近,但是during是介词,不能引导从句。
3.as①as表示点时间时,从句中用持久性动词;表示段时间时,用继续性动词。
as和when两者经常可以通用。

d.假定表示两个急促举措简直同时发作时,用as场所多于when。
