C 7. A 8. B 9. D 10. A 解析： 1. 考查情态动词 can 的用法。根据答语 "Yes, you can"，问句需用 can 提问，表请求许可。 0. 考查祈使句结构。Don't 后接动词原形，构成否定祈使句（Don't do sth.）。 0. 考查 have to 的用法。强调客观要求（“不得不”），主语是 you，用原形 have to。must 强调主观义务，此处更侧重客观需要。 0. 考查 must 的否定回答。Must 开头的问句，否定回答用 "don't have to" 或 "needn't"，表示 “不必”。mustn't 表 “禁止”，与语境不符。 0. 考查祈使句结构。肯定祈使句以动词原形开头，"Be quiet" 表示 “保持安静”。 0. 考查主谓一致和 have to 的用法。主语 she 是第三人称单数，故用 has to（客观需要）。 0. 考查 can 的否定回答。Can 开头的问句，否定回答用 can't，表示 “不能”。 0. 考查否定祈使句。Don't 后接动词原形，构成 “Don't do sth.” 结构。 0. 考查主谓一致和 have to 的用法。主语 they 是复数，用 have to（客观规定）。 0. 考查 must 的用法。根据答语 "Yes, we must"，问句用 must 提问，表 “必须”。 0. 补全句子 答案： 1.Don't run 0. must get 0. can play 0. has to 0. listen to 0. can't eat 0. must follow 0. Can; go 0. don't have to 0. Keep; clean 解析： 1. 否定祈使句：Don't + 动词原形（run）。 0. 情态动词 must + 动词原形：“必须到达” 用 must get。 0. 情态动词 can + 动词原形：“可以做某事” 用 can do sth.。 0. 主谓一致和 have to：主语 he 是第三人称单数，故用 has to。 0. 固定搭配：listen to music（听音乐），祈使句中用动词原形。 0. 情态动词 can 的否定：can't + 动词原形（eat）。 0. 情态动词 must + 动词原形：“遵守规则” 用 follow the rules。 0. 情态动词 can 引导的一般疑问句：Can + 主语 + 动词原形（go）。 0. have to 的否定形式：主语 you 是第二人称，否定用 don't have to。 0. 祈使句：Keep sth. + 形容词（clean），表示 “保持某物……”。 三、单词填空 答案： 1. be 2. run 3. play 4. wear 5. eat 0. clean 7. come 8. listen 9. get 10. help 解析： 1. 情态动词 must 后接动词原形：must be quiet（必须安静）。 0. 否定祈使句中 Don't 后接动词原形：Don't run（不要跑）。 0. 情态动词 can 后接动词原形：can play（会弹）。 0. have to 后接动词原形：have to wear（必须穿）。 0. 情态动词 can't 后接动词原形：can't eat（不能吃）。 0. 情态动词 Must 后接动词原形：Must I clean（我必须打扫吗）。 0. don't have to 后接动词原形：不必做某事（don't have to come）。 0. 祈使句中 please 后接动词原形：Please listen（请听）。 0. has to 后接动词原形：第三人称单数 has to get（不得不起床）。 0. 情态动词 Can 后接动词原形：Can you help（你能帮助吗）。 学科网（北京）股份有限公司 $$
