American people like to say "Thank you when others help them or say something kind to them. People of many countries do so too. It is a very good habit.

    You should say "thank you "when someone passes you the salt on the table, when someone walking ahead of you keeps the door open for you, when someone says you have done your work well, or you have bought a nice thing, or your city is very beautiful. "Thank you" is used not only between friends, but also between parents and children, brothers and sisters.

    "Excuse me" is another short sentence they use. When you hear someone say so behind you, you know that somebody wants to walk past you without touching you. It's not polite to break others when they are talking. If you want to speak to one of them say.

    "Excuse me" first, and then begin talking. You should also do so when you begin to cough or make any noise before others.

    Let's learn to say "Thank you" and" Excuse me.

    Most English people have three names: a first name, a middle name and a family name. Their family names come last. For example, my full name is Jim Allan Green. Green is my family name. My parents gave me both of my other names.

    le don't use their middle name very much. So "John Henry Brown" is usually called "John Brown". People never use Mr., Mrs. or Miss before their first names. So, you can say John Brown; but you should never say Mr. John. They use Mr., Mrs. or Miss with the family name but never with the first name.

    Some people ask me about my name. "Why do your parents call you Jim? Why do they choose(择)hat name for you?" The answer is they don't call me Jim. They call me James. James is the name of my grandfather.

    In England, people usually call me Jim for short. That's because it is shorter and easier than James.
