[精品]把肯定句改成否定句
[精品]把肯定句改成否定句一、首先，要看肯定句中是否有情态动词，如果有情态动词，直接在情态动词后面加not即可，同时句中如果有some，some就要变成any。
举例如下：1、肯定句：Mike can help you solve the problem.译文：迈克可以帮你解决那个问题。
否定句：Mike can't help you solve the problem. (can't=can not)译文：迈克不能帮你解决那个问题。
2、肯定句：You should lend some money to Mary.译文：你应该借给玛丽一些钱。
否定句：You shouldn't lend any money to Mary. (shouldn't=should not)译文：你不应该借钱给玛丽。
二、如果肯定句中没有情态动词，那就要看句中有无be动词的相应形式，如果有，直接在be动词后面加not，句中有some，some变any。
举例如下：1、肯定句：I am an English teacher.译文：我是一名英语老师。
否定句：I‘m not an English teacher.译文：我不是一名英语老师。
2、肯定句：There are some books on the desk.译文：书桌上有一些书。
否定句：There aren't any books on the desk.译文：书桌上没有书。
三、如果肯定句中既没有情态动词，也没有be动词，那么就要用相应的助动词加上not来变换，句中有some，some变any。
举例如下：1、肯定句：She likes helping others.译文：她喜欢帮助别人。
否定句：She doesn't like helping others.译文：她不喜欢帮助别人。
2、肯定句：They have some apples.译文：他们有一些苹果。
