1. have a bad cold
2. eat too many sweets

5. What's wrong with you
6. don't want to eat anything
7. see the dentist
8. brush our teeth
9. points at
10. is ready to help them

1. “患了重感冒”对应单元短语have a bad cold，主语为I，用动词原形have。
2. “吃太多糖果”对应短语eat too many sweets，shouldn't后接动词原形，sweets是可数名词复数，用too many修饰。
3. “在十点前”对应介词短语before ten o'clock，用于表达时间节点之前。
4. “好好休息”对应短语have a good rest，与go to bed并列，用动词原形。
5. “你怎么了”是询问身体状况的固定句型What's wrong with you?，符合本单元知识点。
6. “不想吃任何东西”译为don't want to eat anything，主语I的否定句用don't，anything用于否定句表“任何东西”。
7. “看牙医”对应短语see the dentist，go to后接动词原形构成go to do sth结构，表去做某事。
8. “刷牙”对应短语brush our teeth，主语为we，用our指代，teeth是tooth的复数，should后接动词原形。
9. “指着”对应短语point at，主语He是第三人称单数，一般现在时动词用points。
10. “乐意帮助他们”对应is ready to help them，be ready to do sth表“乐意做某事”，主语He是第三人称单数，be动词用is。
