4.任务型阅读。

    Different countries and people have different manners(举止).Here are some examples:If you visit a Chinese family,you should knock at the door first.When the door opens,you should not move before the host says “Come in,please.” Before coming into the house in Japan,it is good manners to take off your shoes.In European(欧洲的) countries,even if your shoes are very dirty,it is not necessary to take them off.In England,a guest(客人) always finishes the drink or the food to show that he enjoys it.This will make the host very pleased.
