单选题Many visitors find the fast pace at which American people move very troubling. One' s first impression is likely to be that everyone is in a rush.(74) City people always appear to be hurrying to get where they are going and are very impatient if they are delayed even for a brief moment. (75) At first, this may seem unfriendly to you. Drivers will rush you: storekeepers will be in a hurry as they serve you: people will push past you as they walk along the street. You will miss smiles, brief conversations with people as you shop or dine away from home. Do not think that because Americans are in such a hurry they are unfriendly. Often life is much slower outside the big cities, as is true in other countries as well. Americans who live in cities such as New York, Chicago, or Los Angeles, often think that everyone is equally in a hurry to get things done: they expect others to "push back" , just as city people do in Tokyo, Singapore or Paris, for example. But when they discover that you are a stranger, most Americans become quite kindly and will take great care to help you. Many of them first came to the city as strangers and they remember how frightening a new city can be. If you need help or want to ask a question, choose a friendly-looking person and say, "I am a stranger here. Can you help me? Most people will stop, smile at you, and help you find your way, or answer your questions. But you must let them know that you need help. Otherwise they are likely to pass you by, not noticing that you are new to the city and in need of help. Occasionally, you may find someone too busy or perhaps too rushed to give you aid. If this happens, do not be discouraged: just ask someone else. Most Americans enjoy helping a stranger.
