We can say “please” “thank you” and “excuse me” every day.
Follow the rules! Let’s be great students and friends!

1. 原文提到在课堂上我们要保持安静、听老师讲课，有想法要分享时可以举手发言，并不是完全不能说话，该句表述错误。
2. 文中的校规涵盖课堂、和朋友相处、操场活动、日常礼貌等多个校园场景，并不是只需要在操场遵守规则，该句表述错误。
3. 原文说明做到礼貌的方式包括日常说“please”“thank you”“excuse me”，所以说“thank you”和“please”是有礼貌的表现，该句表述正确。
4. 原文提到校规每天都帮助我们，文末也提到遵守规则可以让我们成为优秀的学生，所以这些规则能帮助我们成为好学生，该句表述正确。

1. 空格后说明地板是湿的，妈妈是在提醒Bob注意安全避免滑倒，B选项“Be careful.（小心）”符合该语境。
2. 空格后说明在沙发上玩耍不安全，要求Bob坐下，妈妈是在提醒Bob注意安全，B选项“Be careful.（小心）”符合该语境。
3. 空格前Bob询问能否去公园，妈妈同意后转折提出前提要求，C选项“But you have to do your homework first.（但是你得先做作业）”完全符合对话逻辑。
