2017届高考英语一轮复习热点课件：第11节状语从句高效语法

　　第11节

　　状语从句

　　一、让步状语从句 1．用when 和while引导让步状语从句。不要认为when和while只引导时间状语从句，其实它们也可引导让步状语从句，意思是“尽管”或“虽然”。 She stopped when she ought to have continued. 尽管她应该继续下去，她却停住了。 While I understand what you say, I can't agree with you.

　　虽然我理解你的意思，但我还是不同意。 2．用whether…or…引导的让步状语从句。 I'll do it whether you like it or not. 不管你是否喜欢，我都要做。 3．用whatever, whoever, however, whenever, wherever 等引导的让步状语从句。 (1)均可引导让步状语从句，意为“无论……” Whatever you say, I believe you. 无论你说什么，我都相信你。 Whoever telephones, tell them I'm out. 不管是谁打电话，都说我出去了。 Whenever you come, you are welcome. 无论你什么时候来，都是受欢迎的。 (2)引导让步状语从句时，通常可换成no matter… No matter what you say, I believe you. 无论你说什么，我都相信你。 No matter how much he eats, he never gets fat. 无论他吃多少，他都不发胖。 (3)注意however用于以下两类句型的用法。 ① however＋主语＋谓语 However you travel, it'll take you at least three days. 不管你怎么走，至少要3天。 ②however＋形容词或副词＋主语＋谓语 However cold it is, she always goes swimming. 不管天多冷，她都会去游泳。有时该结构中的主语和谓语可以有所省略： He was of some help, however small. 他总能帮些忙，不管多小的忙。 (4)有时从句谓语可用情态动词。 I'll find him, wherever he is (may be).
