J：（1）　　

M：I don't know．

J：Well，Mei．（2）　　．It's a good idea to learn what that person did．

M：OK，I will ask Ms． Robert．But I need to get started today．How should I tell other students about the event？

J：（3）　　 Everyone sees that．

M：Great idea!

J：（4）　　Put signs on the rubbish bins （垃圾桶） to remind students not to drop litter．I can help you with that．

M：That's clever．If we start keeping the school clean，there'll be less work to do on clean﹣up day．

J：That's right！And one more thing，you might try talking to teachers．（5）
