Step 3 Explanation 句型“Do you have…?” “表示你有……吗？”，用于询问物品的所属关系。这是实义动词的一般疑问句结构。

1. 当主语是第一人称/第二人称/第三人称复数时, 句型结构为：Do + you/they/we/… + 动词原形

+ …？

不管用什么动词，它的回答是固定的。

肯定回答：

Yes, I do./ Yes, we do. / Yes, they do.

否定回答：

No, I don’t /we don’t. /No, they don’t.

e.g. — Do they like basketball?

他们喜欢打篮球吗？

— Yes, they do. 是的，他们喜欢。

—

No, they don’t. 不，他们不喜欢。

2. 当主语为第三人称单数时，句子结构改为：

Does + he / she / it … + 动词原形

+ …？

肯定回答：Yes, he does./Yes, she does./Yes, it does.

否定回答：No, he doesn’t./No, she doesn’t /No, it doesn’t.

e.g. — Does Jane have a new book?

简有一本新书吗？

— Yes, she does. 是的，她有。

—

No, she doesn’t. 不，她没有。

3.do和does的用法

do 这个词（does是第三人称单数形式）大体上从两方面来讲。

1）.do作为行为动词，跟其他动词一样，如study, play等。它的意思是“做”等。如：

We usually do our homework in the afternoon. He does his homework in the evening. 2).do作为助动词，也就是帮助主要动词构成否定和疑问等。

We don't like bananas. He doesn't like swimming. 3).作为助动词的do和does是没有词义的，它们在句中构成一般现在时的疑问句和否定句. do用于主语第一人称、第二人称和第三人称复数形式的句中，does用于主语第三人称单数的句中。

Do you want to be a teacher?

你想成为一个老师吗？

Do his friends go to park every day?

他的朋友们每天都去公园吗？
