注意:have的第三人称单数形式是has,而have是它的原形。

2. 主语为第三人称单数时,可以归纳为使用单数形式的动词。

2. He often has dinner at home. (正确形式: He often has dinner at home.)

3. Lucy has a bat.

4. My cousins have two tennis balls.

5. Bob and Mike have a desk.

6. Your parents read newspapers every day.

陈述句的两种形式:

1. 主语+be动词+其他

2. 主语+行为动词+其他

特别要注意的是,主语后不能同时使用be动词和行为动词。

变否定句的规则:

1. 含有be动词的句子,直接在be动词后加not。

2. 不含be动词的句子,在主语后(动词前)加助动词don't或doesn't,第三人称单数主语前加doesn't,其他主语前加don't。

7. I don't have a pen.</

8. Jim doesn't have a pen.</

9. We don't watch TV on Monday.</

10. Nick doesn't go to the zoo on Sunday.</

变一般疑问句的规则:

1. 含有be动词的句子,将be动词提前。

无be动词的句子,用助动词do或does提前。

(主语为第三人称单数时,用does,其他情况用do)

(注意:句尾需加问号)

(回答时用Yes/No和相应的缩写形式)

(肯定回答用Yes, 主语+do/does. 否定回答用No, 主语+don't/doesn't.)

(例如:Do you have a computer? Yes, I do. No, I don't.)

(如:

13. Do you have a computer?

14. Does Tom have a dictionary?

-Does Tom have a book? -No, he doesn't.</

- Do they have soccer balls? - Yes, they do.</

- Does she go to work by bike? - No, she doesn't.</

(答案中需根据实际情况替换“have”为“has”或“hasn't”等)

(如:肯定回答中的“have”在主语为第三人称单数时改为“has”,且缩写为“doesn't”等)

- 某类单词仅表示运动(如tennis网球(运动)、ping-pang乒乓球(运动)、soccer足球(运动)等。当表示某种球时,需在球类单词后加ball,如tennis ball网球(物体)。

- Let's go表示“让我们走吧”。

(例如:Let's play basketball.) (Let me help you.) (My mom doesn't let me watch TV.)</

- That sounds good意为“那听起来很好”。
