四、选句子，补全对话。
1. A: What are you doing, little Mike?
B:
A: Oh, no. We should protect the City Wall.
B: I'm so sorry. I won't do it again.

2. A:
B: She doesn't feel well. She has a bad cold.
A:
B: Yes.
A: How about going to see her after school?
B: OK.

1. 第一空：I'm writing my name on the City Wall.；第二空：It is a very bad habit.
2. 第一空：What's wrong with your English teacher?；第二空：I'm sorry to hear that. She should see a doctor.；第三空：She goes to hospital today. And the doctor tells her to have a good rest.

1. 第一题第一空：问句使用现在进行时，询问对方正在做什么，需要回答正在进行的动作，匹配句子"I'm writing my name on the City Wall."；第二空A制止Mike的不当行为，点明该行为的错误性，和后文“我们应该保护城墙”逻辑对应，匹配句子"It is a very bad habit."。
2. 第二题第一空：B回答自己的女老师身体不舒服、得了重感冒，可知A是在询问这位女老师的身体状况，匹配句子"What's wrong with your English teacher?"；第二空得知他人生病的消息，要表达遗憾并给出看医生的合理建议，匹配句子"I'm sorry to hear that. She should see a doctor."；第三空B用Yes回应后，补充说明老师已经就医的情况，匹配句子"She goes to hospital today. And the doctor tells her to have a good rest."，和后续相约放学后去看望老师的对话逻辑通顺。
