C　2. A　3. D　4. D　5. B 【解析】1. brush your teeth、rest your eyes、see a doctor 都是健康好习惯；check your phone 是坏习惯。 2. toothache、headache、fever 都是疾病；candy 是食物。 3. should、shouldn't、don't 都是劝告用语；can 是能力情态动词。 4. twice a day、every day、often 都是频率表达；day 是时间名词。 5. healthy、good、well 都是积极健康的；bad 是不好的。 二、健康词汇站 1. teeth　2. check　3. teeth　4. rest　5. toothache　6. care 【解析】1.brush your teeth 刷牙，tooth 的复数是 teeth。 2.check your phone 看手机。 3.be bad for your teeth 对牙齿有害。 4.rest your eyes 让眼睛休息。 5.have a toothache 牙疼。 6.take care of 照顾、爱护，固定搭配。 【易错点】tooth 的复数是不规则变化 teeth；take care of 是固定短语。 三、小小翻译家 1. brush your teeth　2. twice a day　3. take care of your eyes 4. be bad for your teeth　5. 看手机　6. 让眼睛休息 7. 少吃糖　8. 不要在床上看书。 【解析】twice a day 一天两次；be bad for 对……有害；Don't 开头是否定祈使句。 四、选词填空 1. should　2. Don't　3. shouldn't　4. Don't 5. should　6. shouldn't　7. Don't　8. should 【解析】好的习惯用 should（应该）；不好的习惯用 shouldn't（不应该）； 强烈禁止的用 Don't（不要），语气最强。 刷牙、多吃蔬菜、饭前洗手是好习惯；吃太多糖、看手机太久、在床上看书、跑走廊是坏习惯/危险行为。 【易错点】Don't 是祈使句的否定，直接放在句首；shouldn't 前面要有主语。 五、单项选择 1. B　2. A　3. D　4. C　5. B　6. D 【解析】1.牙疼不应该吃太多糖，用 shouldn't。 2.take care of 固定搭配，「照顾、爱护」。 3.Don't 后面跟动词原形 read。 4.be bad for 固定搭配，「对……有害」。 5.twice a day 一天两次，固定表达。 6.眼睛累了应该休息眼睛，选 D rest your eyes。 【易错点】take care of 和 be bad for 都是固定短语，介词不能换。 六、情景交际 1. A　2. E　3. B　4. F　5. G（多余项：C、D） 【解析】1.牙医先问怎么了，选 A What's wrong with you?。 2.回答症状，选 E I have a toothache.。 3.检查后给出建议，不应该吃太多糖，选 B You shouldn't eat too much candy.。 4.后面回答 Yes, you should...，问句是 Should 开头的一般疑问句，选 F。 5.对方说 Thank you，回答不客气，选 G You're welcome.。 【易错点】通读对话，按照「问病情→说症状→检查→给建议→问问题→回答」逻辑选择。 七、句型转换 1. You shouldn't brush your teeth twice a day. 2. shouldn't 3. Should I/we rest my/our eyes often? 4. What's 5. not good for 6. should 【解析】1.should 的否定是 shouldn't。 2.Don't eat too much candy. = You shouldn't eat too much candy. 3.变一般疑问句把 should 提前。 4.What's wrong with you? = What's the matter? 你怎么了？ 5.be bad for = be not good for 对……不好。 6.主语换成 he，should 不变，情态动词没有人称变化。 八、适当形式填空 1. brush　2. read　3. eat　4. take　5. eyes　6. eyes 【解析】1-4题都在情态动词 should / shouldn't / Don't 后面，用动词原形。 5-6题：眼睛是两只，用复数 eyes。 【易错点】情态动词后面永远跟动词原形；eye 的复数直接加 s。 九、句子医生 1. eats → eat　2. reading → read　3. for → of 4. to → for　5. brushes → brush 【解析】1.shouldn't 后面用动词原形。 2.Don't 后面用动词原形。 3.take care of 固定搭配，用 of。 4.be bad for 固定搭配，用 for。 5.should 后面用动词原形。 【易错点】所有情态动词和祈使句后面都跟动词原形。 十、连词成句 1. You should brush your teeth twice a day. 2. Don't read in bed. 3. Too much candy is bad for your teeth. 4. How can I take care of my eyes? 5.

Four students. / 4 students. 　2. They often have tired eyes. 　3. Eight students. / 8 students. 【解析】先定位数字和关键词，在原文中圈画出对应的句子，再回答问题。 任务三（参考答案）： 　I sometimes watch TV too late. I should go to bed earlier. I also should read more books. 【解析】说清楚自己的坏习惯和改进计划，语法正确即可。 十二、小小健康顾问（参考答案） 感冒了：You should drink more water. / You should rest. — You shouldn't go to bed late. / Don't run too much. 牙疼：You should brush your teeth twice a day. / You should see a dentist. — You shouldn't eat too much candy. 眼睛累：You should rest your eyes. / You should look at green trees. — You shouldn't check your phone so often. / Don't read in bed. 【解析】根据不同问题给出合理的健康建议，should 和 shouldn't/Don't 各一条。 十三、微写作（参考答案） My healthy habits I have some good healthy habits.
