2012年高考英语二轮复习 状语从句学案

课题名称二轮复习—— 状语从句学 习 目 标 ： 状语从句的各种类型，并正确使用从属连词学 习 难 点 ： 状语从句中的时态表达法在复合句中修饰主句中的动词、形容词和副词的从句叫状语从句。状语从句根据它表达的意思不同可分为时间状语从句、地点状语从句、条件状语从句、比较状语从句、目的状语从句、结果状语从句、方式状语从句、让步状语从句和原因状语从句等。状语从句如果放在主句前通常用逗号分开。一 、 复 习 时 需 注 意 的 要 点1、如果 hardly, scarcely 或 no sooner 等置于句首，句子必须用倒装结构：例如：Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to rain.2、Not until …在句首，主句用倒装。例如：Not until the early years of the 19th century did man know what heat is.直到 19 世纪初，人类才知道热能是什么。Not until I began to work did I realize how much time I had wasted. 直到我开始工作，我才认识到了我已蹉跎了几多岁月。3、当从句的动作发生于主句动作之前，只能用 when 引导这个从句，不可用 as 或 while。例如：When you have finished your work, you may have a rest.4、如从句表示"随时间推移"，连词能用 as，不用 when 或 while。例如：As the day went on, the weather got worse. 日子一天天过去，天气越变越坏。5、as, though 引导的倒装句as / though 引导的让步从句必须把表语或状语提前（形容词、副词、分词、实义动词提前）。句首名词不能带任何冠词。如句首是实义动词，助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起用心 爱心 专心1放在主语之前。例如：Child as /though he was, he knew what was the right thing to do.= Though he was a small child, he knew what was the right thing to do.Try hard as he will, he never seems able to do the work satisfactorily.= Though he tries hard, he never seems…虽然他尽了努力，但他的工作总做的不尽人意。二 、 历 届 高 考 试 题 分 析例 1、Generally speaking, _________ according to directions, the drug has no sid-effect.A. when taking B. when ta...
