总结:
1.中考对状语从句的考查会和从属连词相结合,主要为在状语从句中考查从属连词的辨析及应用,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。
2.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。
状从精讲
定义:状语从句在主从复合句中修饰主句。状语从句都是由从属连词引导,与主句连接。位于句首时,常用逗号分开;位于句末时,其前一般不用逗号。
结构:主句+连词+从句或者连词+从句+,+主句,根据状语性质的不同可以分为以下八种状语从句: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,比较状语从句,让步状语从句和方式状语从句。
