状语从句专项练习50题
状语从句专项练习50题1. I was doing my homework ______ my mother was cooking dinner.A. whileB. whenC. asD. until答案：A。
本题考查时间状语从句连接词的用法。
“while”强调两个动作同时进行，“我在做作业”和“我妈妈在做晚饭”两个动作同时发生，所以用“while”。

“as”表示“随着”，不符合句意。
“until”表示“直到”，与句意不符。
2. ______ I was walking in the park, I saw a beautiful bird.A. WhileB. WhenC. As soon asD. Before答案：B。
“when”在此表示一个动作正在进行时，另一个动作突然发生，“我正在公园散步时，看到了一只漂亮的鸟”。

“since”表示“自从”，不符合句意。

(完整版)高考英语状语从句专项训练
专题十一状语从句状语从句在高考试题中由于其他从句的干扰，以及倒装句,强调句的介入，使得状语从句更为复杂。
状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。
状语从句1. 时间状语从句常见的连词(组）：when, while， as， before, after, once, till, until， as soon as， now that， hardly 。
..when, scarcely 。
.when， no sooner .。
than等.可以引导时间状语从句的副（介)词（短语）或名词短语：directly， instantly， immediately, by the time, the moment, the second， the minute， the instant, every time, each time， next time， the last time等。
注意点如下：(1） when， while, as引导的时间状语从句as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。
when(at or during the time）既可以表示在某一点的时候，又可以表示在某一段时间内,主句与从句的动作或事情可以同时发生也可以先后发生.while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态;当when表示a period of time时，两者可以互换。
She came up as I was cooking。
(同时）在我做饭时，她走了过来.When we were at school, we went to the library every day.(在一段时间内）当我们在学校时，每天都去图书馆。
While they were watching TV, I was preparing myself for the coming examination.他们在看电视，而我在为即将到来的考试做准备.Strike while the iron is hot。
