为什么提问用has,回答用的have?
Has the post arrived yet?It may have arrived.为什么提问用has,回答用的have?
这是个现在完成时的句子,结构是： 助动词have/has + 过去分词, 在改一般疑问句时把have/ has提前到句首, 而the post 是单数,相当于it,所以提问用： Has.,Has the post arriven yet? 邮件到了么? 而答句中因为有情态动词 may, 情态动词有跟动词原形,所以用nave. It many have arrived.可能已经到了.
may后跟动词原形
笨蛋！前面用的的是现在完成时：the post has done it的结构，下句是情态动词may的后面一定要用动词原形！
本句用完成时态因为有yet，这是一个完成时标志。the post 是单数用has，而may为形态动词后面要接动词原形have。
