单选题 What must you do when you receive a present for your birthday? You have to sit down and write a thank you note. The words "thank you" are very important, we have to use them all the time. We say them when someone gives us a drink, helps us to pick up things, lends us a book or gives us a present.
Another important word is "please". Many people forget to use it. It is impolite(不礼貌) to ask some one to do something without saying "please". We have to use it when we ask for something, too. It may be a book or a pencil, more coffee or bread, help or advice. It may be in the classroom, at home, or at the bus stop. We have to use "please" to make request(要求) pleasant.
We have to learn to say "sorry", too. When we hurt someone's feeling, we will have to say we are sorry. When we do something wrong and feel sorry, we will have to use the same word. When we have forgot some thing or broken a promise, we will have to explain with that word, too. "Sorry" is a healing(和解) word. We can make people forget wrong by using it sincerely(真诚地).
These words are simple but important. They are pleasing words 'to use in any language.
