如何将一个肯定的陈述句改为一般疑问句:

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、
