考点 21 时间&地点&原因&条件状语从句（核心考点精讲练）

历年高考对状语从句得考查集中在九大状语从句上，尤其是when, ,while, as等等从属连词引导的时间状语从句、让步状语从句、条件状语从句上。预计2023年高考仍然对状语从句的考查将集中在一以下几点。
1.主要考查状语从句连接词的正确运用，其次是状语从句的省略(非谓语动词短语与状语从句之间的转换)；
2.高考对状语从句的考查仍将不会单纯考查其语法结构，而是将其融入一定的语境中来考查考生的实际综合运用能力。
3. 状语从句中的省略(非谓语动词短语与状语从句之间的转换)；
4.状语从句和定语从句、名词性从句的区别；

作状语的句子为状语从句，修饰主句中的动词、形容词或副词等。状语从句放在主句之前时，常用逗号隔开;放在主句之后时，一般不用逗号。状语从句按其意义和作用可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等。引导状语从句的连词归纳如下:
