小学英语句型转换和时态讲解与练习

否定句：

be动词（am、is、are）+not、

情态动词can+ not、

助动词（do、does）+ not

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，直接在be动词后+ not。

2、看句中有无情态动词，如有，直接在情态动词后+ not。

3、如上述二者都没有，就应用助动词+ not。分四个步骤：

（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，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，

$

（3）在助动词后加not。

（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。
