第三人称单数怎么用？什么时候用？疑问句怎么用？否定句怎么用？肯定句怎么用？hasn't怎么用？

Question

动词都是什么时候用现在分词、过去分词和过去式？什么时候加ing？do,does怎么用？拜托了！
能具体点么？我想看看更多的答案，感谢。
您的这个答案我已经看到过了。。

Answer 1

现在进行时要用现在分词，即-ing形式。 e.g.

We are learning English now.

过去式用于一般过去时。过去分词用于现在完成时和被动语态。

Yesterday the 16th Asian Games were held in Guanzhou.

He worked hard last month.

另外， do 和 does用于一般现在时。

I / we; you / you; they 用do.

He / she / it用于第三人称单数。 e.g.

① They do homework every day.

Do they do homework every day? Yes, they do. (No, they don't.)

They don't do homework every day.

② He likes English.

He doesn't like English.

Does he like English？ Yes, he does. (No, he doesn't.)本回答被提问者采纳
