否定句改变方法

表示某一否定意思。句中一定有not。

有三种可能:be动词(am、is、are、was、were)+not、情态动词(can、must、should)+not、助动词(do、does、did)+not

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)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。
