阅读理解。 Canadians like to say 'Thank you' when others help them or say something kind to them. People of many other countries do so, too. It's a very good habit. You should say 'Thank you' when someone passes you the salt on the table, or opens the door for you, or says you have done your work well. 'Thank you' is used not only between friends but also between parents and children, brothers and sisters, husbands and wives. 'Excuse me' is another useful short expression. When you hear someone say so behind you, you know somebody wants to walk past without touching you. It's not polite to interrupt (打断) others when they are talking.
