课时七：肯定句变为否定句的方法一般疑问句的回答1）肯定句变为否定句的方法
把肯定句改成否定句分以下情况：
1、句中有be动词的，在be动词后加not；
2、句中有情态动词的（can ,should，must ，would），在情态动词后面加not；
3、句中没有be动词和情态动词的，在动词前加d on’t或doesn’t ；
①句中动词为原形的，加d on’t.如： I like apples. →I do n’t like apples.
②句中动词为三单式的，加does n’t，并将三单式的动词还原成原形。
如：He likes apples.→ He does n’t like apples.
③时态为过去时的,要加didn’t 而且动词过去式要改为原形,
例:I went to school yesterday .→I didn’t go to school yeaterday .
4.肯定句中的some在否定句中应改为any
如：There are some students in the classroom.→ There are not any students in the classroom.

英语重要知识点 陈述句变成一般疑问句：如果句中有必动词be-v（is am are）要将is、am、are提前（如果有助动词要将助动词“抛弃”，将必动词最提前，不管是助动词还是特殊疑问词，必动词在一般疑问句里就是“老大”[1]；当变一个句子时，如果句子里有be-v动词的话，往往不能在变一般疑问句时加do或does；如果助动词已经使用了第三人称单数形式，那么句子中的动词不得再次使用第三人称单数形式，要变为动词原形[2]）. [1]例：Tom is a student. Does is Tom a student.(×)
Is Tom a student?(√) [2]例：Does he lives in Huang gang（黄冈，中国一城市）.(×) Does he live in Huang gang.(√) 用助动词do或does提问（do用于第一人称和第二人称单、复数和第三人称复数；does用于第三人称单数的he、she、it等）;如果在第一人称的情况下，往往要将第一人称变为第二人称;在变一般疑问句时，要将动词变化为动词原形；如果陈述句里面有many/some，改一般疑问句或者特殊疑问句时，要将many/some改为any.
