We should attach great importance to the influence of culture on language, especially British and American countries and our country's traditional customs, there are a lot of different places, for example, someone ask you: "did you eat?" In China, it is a kind of general greeting. In Anglo-American countries it means that you are going to invite him to your house for dinner. In oral English teaching should not only master the language forms, to know more about its social function.
