1、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 canrun.→I cannotrun. 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,twoapples等），加don’t。如： I like apple
2、s.→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/thisbook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
