7. takes
8. stops
9. teaches
10. shops
11. loves

16. plays
17. worries
18. drives

20. goes

在英语中，动词的第三人称单数形式通常是在动词原形后面加-s或-es。一般来说，以s, x, ch, sh, o结尾的动词加-es，以辅音字母+y结尾的动词，变y为i再加-es，其余加-s。另外，也要注意一些特殊变化的动词，比如have的第三人称单数形式是has。
根据这个规则，我们可以逐一写出每个动词的第三人称单数形式。

二、根据句意,用括号中所给动词的正确形式填空
1. There ______ (be) twelve months in a year.
2. The park ______ (be) beautiful in spring.
3. They often ______ (watch) TV at the weekend.
4. Helen often ______ (do) some shopping with her friends.
5. Tom's parents ______ (not exercise), but Tom ______ (exercise) every day.
6. —How often ______ your grandfather ______ (write) to you?
—Every month.
7. ______ his brother ______ (play) football every day?
8. My father ______ (not drive). He ______ (walk) to work every day.
9. —______ you ______ (like) singing?
—No, I ______.
10. —______ your grandpa ______ (love) singing Beijing opera?
—Yes, ______ ______.

1. are
2. is
3. watch
4. does
5. don't exercise; exercises
6. does; write
7. Does; play
8. doesn't drive; walks
9. Do; like; don't
10. Does; love; he does

1. “There be”句型遵循就近原则，后面的名词“twelve months”是复数，且句子描述的是客观事实，所以用一般现在时“are”。
2. 主语“The park”是单数，句子描述公园在春天的状态，用一般现在时“is”。
3. “often”表明是一般现在时，主语“They”是复数，所以动词用原形“watch”。
4. “often”表明是一般现在时，主语“Helen”是第三人称单数，所以动词用第三人称单数形式“does”。
5. 第一空，主语“Tom's parents”是复数，否定句借助助动词“don't”，后面动词用原形“exercise”；第二空，主语“Tom”是第三人称单数，动词用第三人称单数形式“exercises”。
6. “How often”询问频率，用一般现在时，主语“your grandfather”是第三人称单数，借助助动词“does”，后面动词用原形“write”。
7. 一般现在时的一般疑问句，主语“his brother”是第三人称单数，借助助动词“Does”，后面动词用原形“play”。
8. 第一空，主语“My father”是第三人称单数，否定句借助助动词“doesn't”，后面动词用原形“drive”；第二空，主语“He”是第三人称单数，动词用第三人称单数形式“walks”。
9. 一般现在时的一般疑问句，主语“you”，借助助动词“Do”，后面动词用原形“like”；否定回答是“No, I don't”。
10. 一般现在时的一般疑问句，主语“your grandpa”是第三人称单数，借助助动词“Does”，后面动词用原形“love”；肯定回答是“Yes, he does”。
