肯定句变否定句习题训练
知识点总结:
把肯定句改成否定句分以下情况:
1、 句中有be动词(am, is, are, was,were)的,在be动词后加not;
2、 句中有情态动词的(can , should, must , would等),在情态动词后面加not;
如: I can run.→I can not run.
3、 句中没有be动词和情态动词的,在动词前加don’t或doesn’t :
① 句中动词为原形的(即主语为第一人称I/we、第二人称you,第三人称复数they, two apples
等),加don’t。如: I like apples.→I don’t like apples.
②句中动词为三单式的(即主语为第三人称单数he/she/it/this book等),加doesn’t,并将三单
式的动词还原成原形:
如:He likes apples. → He doesn’t like apples.
③时态为过去时的,要加didn’t 而且动词过去式要改为原形:
例:I went to school yesterday . →I didn’t go to school yesterday .
4.肯定句中的some在否定句中应改为any
如:There are some students in the classroom. →There are not any students in the classroom.
