三、用所给单词的适当形式填空。
1. (do) arrive late for school.
2. We mustn't eat (snack) in class.
3. I'd like to read (quiet) in the study.
4. Modern music is just like (noisy).
5. I want to get (good) grades after working hard.
6. We can't make our room (tidy).
7. Listening to music can make me (relax).
8. If you don't feel (well), you should go to the doctor.
9. Some students don't want to wear the school (uniform).
10. I have to (follow) many rules at school.

1. Don't；2. snacks；3. quietly；4. noise；5. better；6. untidy；7. relaxed；8. well；9. uniforms；10. follow

1. 考查祈使句的否定形式，结构为Don't + 动词原形，故填Don't；2. snack是可数名词，此处表泛指，用复数形式snacks；3. 修饰动词read需用副词，quiet的副词是quietly；4. like为介词，后接名词，noisy的名词形式是noise；5. 句意为“努力学习后想取得更好的成绩”，用good的比较级better；6. 句意是“我们不能让房间不整洁”，tidy的反义词为untidy；7. make sb + 形容词，修饰人用-ed形式的形容词，故填relaxed；8. feel well表示身体状况好，well此处为形容词，直接用所给词；9. school uniform意为校服，此处表泛指，用复数uniforms；10. have to后接动词原形，故填follow。

四、按要求完成句子，每空一词。
1. Jack can go swimming on Sunday.（改为否定句）
Jack on Sunday.
2. Let her come in.（改为否定句）
her come in.
3. You mustn't run in the hallways.（改为同义句）
in the hallways.
4. She has to go to bed before 9:00.（改为否定句）
She go to bed before 9:00.
5. He doesn't have to do his homework now.（改为同义句）
He his homework now.

1. can't, go, swimming；2. Don't, let；3. Don't, run；4. doesn't, have, to；5. needn't, do

1. 原句含情态动词can，变否定直接在can后加not并缩写为can't，后接动词原形go和动名词swimming；2. Let型祈使句变否定需在句首加Don't，后接宾语her和动词原形let；3. mustn't表禁止，同义句用祈使句否定结构Don't+动词原形；4. 一般现在时主语she为第三人称单数，has to变否定需借助助动词doesn't，has还原为原形have，后接不定式符号to；5. doesn't have to（不必）的同义表达为情态动词needn't+动词原形do。

五、根据汉语意思完成句子，每空一词。
1. 保持你的校园干净整洁。
