1.be动词(am/is/are)
主语be动词(原形)be动词(过去式)
I am was
He/she/it is was
We/you/they are were
口诀:我用am, 你用are,is用在他她它,所有复数全用are

Are they American?——Yes, they are. /No, they aren’t.
表示疑问,一般回答只有两种可能Yes或No,句中没有疑问词。

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,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/某物)后,动词前。

(2)确定助动词用do、does还是did,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,动词用过去式的助动词就有did。

(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。

有some的要考虑是否要用any
