状语从句1.定义和类型：用来修饰动词，副词和形容词的从句叫状语从句。状语从句分类较多，中考常考的状语从句可分为1、时间状语从句 2、让步状语从句 3、原因状语从句 4、目的状语从句 5、结果状语从句 6、条件状语从句 2.具体分类：连词时间状语从句while, when, before, after, as, till, until, since, as soon as, whenever原因状语从句because/since/as目的状语从句 so that结果状语从句sothat/suchthat条件状语从句 if/unless让步状语从句though/although & even if/even though3. 考点：时间状语从句考until，常常和非延续性动词组合。其次是结合进行时考察when/while/as，再次是结合主将从现考察as soon as/whenever.原因状语从句，主要考察since作为既然的意思。目的状语从句，考察较少。结果状语从句常常考察so.that与such.that的辨析，so+ many/few/much/little+名词结构用用的是so而不是such是一个重要考点。条件状语从句最常考的是unless，相当于ifnot,意为“除非,如果不”。其次结合主将从现考察if的用法让步状语从句，主要考察句子的让步关系一、时态【大桥第二学期模拟题】1.
