American people have the habit of saying “Thank you”when something kind is done for them or something polite is said to them, no matter how easy the thing is. This habit is learned by people of many        countries.
You should say “Thank you”when someone        you the salt on the table, when someone walks aside to let you        in a corridor （走廊）, when someone        ahead of you keeps the door open        you, when someone says your work is well        or you have bought a nice thing, or your city is very beautiful.
“Thank you”is        not only between strangers or new friends, but also between old friends, parents and children, brothers and sisters, husbands and wives. Parents often tell       children that they should say “Thank you”in answer to a kind word or act when they are only four       five years old. Perhaps that’s       almost everyone has got this habit.
