当然填enjoy yourself啊,did是助动词,这后面应该跟动词原形啊

您好，这道题的正确答案是：enjoy yourself （助动词已经体现了时态，后面直接跟动词原形）

祝学习进步O(∩_∩)O
若有疑问，请指出，希望能和你一起探讨~
如果认为我的回答好，请及时采纳，谢谢！

enjoy yourself 因为前面有助动词，动词要变原型。

enjoy yourself
因为前面用了did,后面用动词原形就行了。

enjoy
enjoyed 是过去式
这句话是一个问句，did就是do的过去式，专业术语我说不来，但是前面已经用了did，后面的动词只要用原型就行了。

填enjoy,did助动词就体现了过去式，后面用原形，这是最基础的好好学习哦

填enjoy yourself,助动词后用动词原型
