Read the passage carefully and then decide the best answer from the four choices according to the passage:
American people are always in a hurry. It seems they don’t have time for formality. So American informality is well known. But you may still feel somewhat surprised at this “lack of respect.” This is especially true in the business world. Most Americans have little concern for “rank” or “title”. They often use first names upon meeting people for the first time. They may introduce their friend to you in this way: “Li Hong, this is Mary Smith.” In this situation, you are free to call the lady “Mary” or “Miss Smith”. American people do not always shake hands upon meeting strangers. They often just smile and say “Hi” or “Hello”. To American people, such an informal greeting really means the same thing as a formal handshaking. Similarly, American people do not have a formal “farewell”. They will just wave “good-bye” to the whole group. Or perhaps, they will simply say “Bye” or “So long” and then leave. There are no handshakes in most cases. To Americans, a friendly, informal relationship is the most important thin.
