1、小学英语语法知识 (疑问句) Irene,一般疑问句,Is ? Are ? Was ? Were ? Do ? Did ? Does ? Can ? 一般疑问句的回答只能用Yes或No.,be动词,情态动词,助动词,一般疑问句: 表示疑问，一般回答只有两种可能Yes，或No，句中没有疑问词。 如何将一个肯定的陈述句改为否定句： 1、看句中有无be动词，如有，把be动词提到句首即可。be动词（is 、are、was、were) 2、看句中有无情态动词，如有，把情态动词提到句首即可。 情态动词（can),3、如上述二者都没有，就应把助动提到句首。 助动词（do、did、 does) 分四个步骤：
2、（1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人或某物）后，动词前。 （2）确定助动词用do、does还是did，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，动词用过去式的助动词就有did。 （3）把助动词后提到句首。 （4）原句中动词假如发生变化就要恢复成原形。 强调一点，有some的要考虑是否要用any。,e.g,This is Amys bike.(一般疑问句） Is this Amys bike? Yes, this is. (肯定回答） No, this isnt. （否定回答） Did you go to Beijing las
3、t weekend? Yes, I did. (肯定回答） No, I didnt. (否定回答) I have some books. (一般疑问句） Do you have any books?,变否定句的做法：,1、如句子里是be动词：am,is,are,was,were 就在这些词后加not 例： He is Tom. He is not Tom. 2、如句子里是动词就在这些词前加 dont,doesnt,didnt （1）主语是第一、二人称（复数）加dont，第三人称单数加 doesnt （2）如果是过去式就加didnt 例：I like dogs. She likes swimmi
4、ng. I dont like dogs. She doesnt like swimming. 3、如句子里是情态动词是must,can,may,should 就在这些词后加not 例句：You can watch TV now. You can not watch TV now.,特殊疑问句,表示疑问，有疑问词（在开头），回答有很多种可能。 常用疑问词： When 什么时间 (问时间) Who 谁 (问人) Where 在哪里 (问地点) Which 哪一个 (问选择) Why 为什么 (问原因) What 什么 (问东西、事物) How 怎样 (问方式、手段，程度、情况等),Mike: _
