高中英语2025届高考语法复习状语从句知识讲解
高考英语语法复习状语从句知识讲解一、概述常见的有although/though/even though引导的让步状语从句。
if/unless引导的条件状语从句。
until/when/while/as soon as引导的时间状语从句。
because引导的原因状语从句，so that引导的目的状语从句等。
if引导的条件状语从句和when引导的时间状语从句一般都会和时态相结合，即主要考查“主将从现”原则。
对于状语从句的学习可与专题六从属连词相结合。
在时间状语从句和条件状语从句中，主句和从句的时态一致问题一般有两种情况：（1）“主将从现”：主句用一般将来时，而从句用一般现在时。
常见的使用“主将从现”原则的连词有：表示时间的when, while, after, before, until, till, whenever, as soon as, as long as, once 等；表示条件的if, unless, so long as, in case等。
（2）“主祈从现”：若主句是祈使句，或主句中有情态动词时，那么从句用一般现在时表示将来。
（3）“主情从现”：若主句有情态动词, 那么从句用一般现在时表示将来。
如：You can get good grades if you study hard.如果你努力学习，你将取得好成绩。
状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,其前一般不用逗号。
状语从句根据其用途可分为时间状语从句、条件状语从句、原因状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、地点状语从句等。
二、时间状语从句(1)当主句是一般将来时态或祈使句,表示将来的意义时,从句通常用一般现在时,简称“主将从现”。
I’ll ring you up as soon as I get to Beijing.我一到北京就给你打电话。
(2) when引导的时间状语从句,通常表示主句和从句的动作同时发生;before表示主句的动作发生在从句的动作之前;after则表示主句的动作发生在从句的动作之后;as引导时间状语从句时,往往表示主句和从句的动作同时发生,不分先后。
高中英语状语从句讲解
Adverbial Clauses (状语从句)状语从句在句中作状语，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，常用逗号分开；放在主句之后，一般不用逗号。
状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等9种。
1．时间状语从句(adverbial clause of time)⑪时间状语从句常用连词有when，as，while，before，after，since，till（until），as soon as，hardly …when …，no so oner …than，the moment等。
⑫主句若为一般将来时(will\shall\can或祈使句)，从句要用一般现在时或现在完成时。
①I'll go on with the work when I come back tomorrow. 我明天回来的时候继续干。
②Please tell him about it when you see him back. 你看到他回来，就告诉他这件事。
⑬连词when，while，as都表示“当……的时候”，但有区别。
※When引导的从句中的动词，既可以是延续性动词，也可是非延续性动词。
①When my father came in , I was doing my homework.②John arrived when I was cooking lunch.如果主句和从句的动作是一先一后发生的，只能使用when，先发生的动作要用完成时③When I got to the station, the train had left.※While 从句表示一段时间的动作或状态，从句动词必须是延续性动词。
④He entered the room while I was reading a book.⑤I was cooking/cooked the dinner while I was listening/listened to the piano.※当主句动作发生在从句动作过程中，且从句动作为延续性动词时，可用as,相当于When\while。
