第三人称单数
请问He can not swim. 和 He does not smoke. swim和smoke 后面为什么不加s

一句简单的句子中不可能同时出现两个时态一样的动词,
因此,He can not swim里,前边有一个can,是情态动词,后边swim自然不用三单形式,同样的道理,He does not smoke ,前边用了does ,后边就不用smok的三单形式了.

第三人称单数请问He can not swim. 和 He does not smoke. swim和smoke 后面为请问一个句型,He does not like swim/swimming 是He can not only swim,but also dance还是He not only can swim,b I'm not sure he can swim 改为否定句 Dont smoke和not smoke有什么区别? He does not like running.He would rather swim.（合并句子）He _____ can he swim同义句()he()()swim? He can swim () 1.Years ago,he ____(smoke)but he_____(not smoke)anymore play的单数第三人称和现在分词是什么?swim的单数第三人称和现在分词是什么? you can not smoke here改祈使句 You can not smoke here.改祈使句
