1、看句中有无be动词，如有，把be动词提到句首即可。 2、看句中有无情态动词，如有，把情态动词提到句首即可。 3、如上述二者都没有，就应把助动提到句首。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还是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）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。 小学五年级英语语法：Be动词用法 be动词（am、is、are）+not、 情态动词can+ not、
