八年级英语上册知识点总结：反义疑问句 八年级英语上册知识点总结：反义疑问句 The pictures are beautiful, arent they? Yes, they are. Its a nice day, isnt it? Yes, it is. You like sports, dont you? Yes, I do. It looks like rain, doesnt it? No, it doesnt. 以上疑问句表示说话者对某事已有看法，为了可靠或出于礼貌发问，以求得确切答案，称为反意疑问句。反意疑问句由两个部分组成：陈述句附加疑问句。 注意： 1前一部分肯定，后一部分否定；前一部分否定，后一部分肯定。如： Henry is a good boy, isnt he? She cant drive, can she? 2除there be句型之外，疑问句的主语必须与陈述部分的主语在人称、数、性方面保持一致。如： She went there last Sunday, didnt she? Mr. White was careless, wasnt he? The kite flies very high, doesnt it? They study hard, dont they? We wont go there, will we? 3如果陈述句有一个助动词（包括情态动词），其疑问句用同一助动词（情态动词）。如： You can swim, cant you? He hasnt met my sister, has he? 4当陈述句是“Im 表语”时，由于“am not”无省略形式，附加疑问句用“arent I”代替。如： Im late, arent I? Im a student, arent I? 5当陈述部分是祈使句时，后面的附加疑问句用will you? /wont you?/can you? /cant you?祈使句的否定结构后只能用will you? 如： Open the window, wont you? Sit down, can you? Dont forget, will you? 6如果陈述句是there be结构，在附加疑问句中用be not there结构? 如： There is something wrong, isnt there? There wont be any trouble, will there? 7当前面的陈述句中有含否定意义的如no, never, hardly等词时，应视为否定句，其后的附加疑问句应用肯定。如： He has few friends, does he? You have never been here, have you? She can hardly write her name, can she? 8当陈述部分是lets时，其后附加疑问句用shall we? 当陈述句部分是let us时，其后附加疑问句用will you? Lets go home together, shall we? Let us go home, will you? 9反意疑问句要用yes, no来回答。只要事实是肯定的，用yes；事实是否定的，用no.不管提问时是肯定还是否定。 如：你现在正站着，对下面疑问句的回答完全是一样的。 注意几种时态的区别： 到目前为止，我们已经学习了以下几种时态： （1）一般现在时：表示经常、反复发生的动作或存在的状态。 We study hard at school every day.
