1、中考英语状语从句知识讲解状语从句即指在主从复合句用作状语的从句。按照其意义，状语从句可分为时间状语从 句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步 状语从句等。学习状语从句主要应注意引导状语从句的从属连词的用法与区别，以及从属连 词在一定的语言环境中的意义与用法。一、时间状语从句1 .引导时间状语从句的从属连词很多，常见的有before, after, when, while, as, since, till, until, as soon as 等。2 .表示“当时候”的while, when, as的用法区别是:while从句中的谓语动词必 须是延续性动词

2、；表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时， 只能用when;当表示“一边一边”或“随着”时，只能用as。另外，用于此义的as 所引导的时间状语从句谓语只能是动作动词，不能是状态动词。如下面一道高考题的答案是 B而不能是A:m going to the post office. “ you re there, can you get me somestamps?”A. As B. WhileC. BecauseD. If3 . until在肯定句中通常只连用延续性动词，表示相应动作结束的时间；在否定句中通 常连用非延续性动词，表示相应动作开始的时间，意为“直到才”。如二H

3、e waited until she was about to leave,他等着一直到她准备离开。I did not begin to work till he had gone.他走了后我才开始工作。4 .表示“一就除用 as soon as 外，还可用 the minute, the second, the instant, immediately, directly, instantly, no soonerthan, hardlywhen 等。 如：I came immediately you called.你一来电话我就来了。Hardly had she arrived when
