反意疑问句（Tag question) 反意疑问句的较为繁琐，建议通过多读各个类型的反意问句的方式来培养语感。 1.反意疑问句的陈述部分谓语有have to时，附加疑问句通常用助动词do。 You have to study hard, dont you? I don’t have to get up early, do I? * * * * * * * * * * * * * * * * * * * * * * * * * * * *  * * * * 关系代词what的用法 1. “what is (was)+形容词比较级”，“更……，尤其……”，常作插入语。如：what’s more; what’s worse. Great men are often unknown or what’s worse, mis-known. 2. what既可指人，也可指物，“……的（人或物）”。 e.g. This is what you call fashion? e.g. Never pretend to be what you are not. 3. “what＋名词”相当于“all the+名词＋that”，what在从句中作定语。 e.g. We will give you what help we can. (=all the help that) 真题 She managed to save ___ she could out of her wages to help her brother. A. how little money B. so little money C. such little money D. what little money D BUT 用法 but作关系代词相当于who…not, which…not, that…not。其先行词一般为表示否定意义的词。只用于限定性定语从句。 e.g. There are very few but admire his talents. (but=who don’t) 注：there be结构在此类句型中有时可以省略。 e.g. (There is )No rule but has exceptions. than 用法 关系代词than 一般用于含有比较级的句子中，兼有连词和代词的性质。 e.g. You spent more money than was intended to be spent. e.g. The question is more complicated than appears on the surface. 定语从句与强调结构 It is the place where they lived before. It is in the place that they lived before. 第一个句子为定语从句，where指代the place，在定语从句中作状语，第二个句子为强调结构，强调in the place, that没有意义，把放回后面句子，句子意思完整。 Where is it that he found the lost watch? (强调句型，强调疑问副词where.) Where is the watch that he found yesterday? (定语从句，that指代the watch.) 定语从句中的先行词 Is this book the one that you bought yesterday? Is this the book that you bought yesterday? 第一个句子中，this book是主句的主语，the one是先行词。在第二个句子中this是主句的主语，the book是先行词。一定要避免出现：Is this book that you bought yesterday?  1.
