Nice to meet you.Ali: You, too.Tom: How long have you been in the United States?●Dialogue AnalysisMaria not only introduces Tom and Ali, but she also gives information about each of them. Why is that helpful?If Tom were just passing by, do you think Maria would still introduce him to Ali?What expression does Tom use when he is introduced to Ali? How does Ali respond?What might give you the impression that Tom is a friendly person?●Points to Remember★When you first meet most American's, it's impolite to talk about certain things such as salary, age, sex, and religion.★Introduce yourself casually in informal situations. As the conversation develops, a simple introduction , such as "By the way, my name is..." is generally considered sufficient.★If a friend comes along and stops to talk, informally introduce him or her to the person you are talking to. It is helpful to provide some information about each of them so that each will 1) know what your relationship is to the other person (friend, neighbor, wife, brother, teacher) and 2) have some information with which to begin a conversation.★When we are introduced to someone informally, we usually respond with "Nice to meet you" or "Hi, how are you?" "How do you do?" is used in more formal situations and the response to this expression is generally "How do you do?"。
