Grammar（第四课时） 让步、结果和目的状语从句 1.让步状语从句 让步状语从句表示即便出现从句中的情况，主句动作仍然会发生。常用连词although或though来引导让步状语从句，两者均意为“尽管，虽然”。在一般情况下，两者可以互换。although比though正式，though常用于口语中。though/although引导的让步状语从句不能与but连用，但可 ‹#› 知识概要 课时讲练 知识清单 2 以和still/yet连用。它们引导的让步状语从句可以放在主句之前，也可以放在主句之后。例如： Although/though he is poor, he’s still happy. =He is poor, but he’s still happy. 虽然他很穷，但他仍然很快乐。 Although/though jeans were invented over 100 years ago, still/yet they’re in fashion today. 尽管牛仔裤在100多年前就被发明了，现在它们仍然很流行。 ‹#› 知识概要 课时讲练 知识清单 2.结果状语从句 结果状语从句用来补充说明主句动作发生所带来的结果。“so/such ... that”意为“如此……以至于……”，常用来引导结果状语从句。 （1）“so...that”引导的结果状语从句 so在此处是副词，其后接形容词或副词，其句型结构为：so +形容词/副词+ that从句。例如： Mr. Smith is always so busy that he has little time for his family. 史密斯先生总是很忙，几乎没有时间陪家人。 Alice worked so hard that she got the first place in the exam. 爱丽丝学习如此努力，以至于在考试中得了第一名。 ‹#› 知识概要 课时讲练 知识清单 4 【拓展】“so...that”结构的句型转换： ① 当that引导的从句是否定句，且主从句的主语一致时，可与“too...to...”结构进行转换；若主从句的主语不一致，可与“too...for sb. to...”结构进行转换。例如： He is so young that he can’t go to school.→He is too young to go to school. 他太小了，还不能去上学。 The bag is so heavy that she can’t move it.→The bag is too heavy for her to move. 这个袋子太重了，她挪不动。 ‹#› 知识概要 课时讲练 知识清单 5 ② 当that引导的从句为肯定句，且主从句的主语一致时，可与“...enough to do sth.”结构进行转换；若主从句主语不一致，可与“...enough for sb. to do sth.”结构进行转换。例如： Mary is so old that she can go to school.→Mary is old enough to go to school. 玛丽足够大了，可以去上学。 The Maths problem is so easy that I can work it out.→The Maths problem is easy enough for me to work out. 这道数学题太简单了，我可以解出来。 ‹#› 知识概要 课时讲练 知识清单 6 （2）“such...that”引导的结果状语从句。其句型结构有以下三种基本情况： ①such+a（n）+形容词+可数名词单数+that从句 This is such an interesting book that we all enjoy reading it. 这本书很有趣，我们都喜欢看。 ‹#› 知识概要 课时讲练 知识清单 7 ②such+形容词+可数名词复数+that从句 These are such beautiful flowers that we want to take photos of them. 这些花真漂亮，我们想给它们拍照。 ③such+形容词+不可数名词+that从句 Jim has made such great progress that his parents are proud of him. 吉姆取得了如此大的进步，他的父母为他感到骄傲
