一、班主任李老师正在和同学们讨论班级规则。听对话，用数字 1—5 给下列图片排序。

5 4 3 1 2

根据Unit 1 Class rules主题，听力对话围绕班级规则展开，涉及"不要跑、不要扔纸、不要乱扔垃圾、保持整洁、互相帮助"等场景。图片从左到右依次对应"帮助同学、扫地、乱扔垃圾打叉、门口跑打叉、黑板扔纸打叉"。听力中规则顺序为：不要跑（图4）→不要扔纸（图5）→不要乱扔垃圾（图3）→保持整洁（图2）→互相帮助（图1），故排序为5 4 3 1 2。

二、李老师正在制作班级规则清单。请圈出合适的单词补全句子。
1. Please keep the classroom (ready / clean). Sweep the floor every day.
2. Hurry up! (Don't / Please) be late for class.
3. Please be (nice / bad). We are friends.
4. You can't take (books / toys) to school.
5. Don't (run / read) in the classroom.

1. clean
2. Don't
3. nice
4. toys
5. run

1. 根据“Sweep the floor every day.”可知是要保持教室干净，所以选“clean”。
2. “Hurry up!”以及不被允许迟到，要用否定“Don't”。
3. “We are friends.”表明要友好，所以是“nice”。
4. 通常学校不允许带玩具，“books”是书可带，这里应选“toys”。
5. 在教室不能跑，“run”符合语境。

三、提升题 Lisa 正在向新来的同学 Leo 介绍班级规则。请选择合适的句子补全对话。
Leo：Look! These are my new toy cars.
Lisa：1.
Leo：I'm sorry. I don't know that.
Lisa：2.
Leo：Yes, it is.
Lisa：3.
Leo：OK.
Lisa：Look! 4.
Leo：Wow! There are so many rules on it.
Lisa：These rules are good for us. 5.
A. This is our class rule list(清单).
B. We can't eat in class.
C. Oh, you can't take toys to school.
D. Let's follow them together!
E. Is this your bread?

1. C
2. E
3. B
4. A
5. D

1. C：从Leo说“Look! These are my new toy cars.”以及后面道歉“I'm sorry. I don't know that.”可知Lisa说的是不能带玩具到学校，C选项“Oh, you can't take toys to school.”符合语境。
2. E：根据Leo回答“Yes, it is.”可知问句是一般疑问句，E选项“Is this your bread?”符合，且结合后文提到规则，吃的东西相关规则合理。
3. B：前面提到规则，这里Lisa继续说规则内容，“We can't eat in class.”是关于课堂规则的表述，符合语境。
4. A：从Leo说“Wow! There are so many rules on it.”可知Lisa说的是有个规则清单，A选项“This is our class rule list(清单).”符合。
5. D：前面说规则对我们好，D选项“Let's follow them together!”呼吁一起遵守规则，符合语境。
