     Don't_believe_all_of_the_stereotypes(模式化的形象)you_may_have_heard_about_Americans.Even the ones that are true in general may not be true about specific individuals or a large part of the population.For example,although Americans tend to be louder than people from other cultures(especially at athletic

events),many of the people you meet will be quiet and polite.Some people may be intolerant, but most will be pleasant and welcoming.Remember that American films and television exaggerate(夸张)in order to

generate excitement, and so present a rather false picture of what life in the United States is really like.

Therefore,tourists in the US are not always on their best behavior.

     Americans do tend to be more informal than people from other countries.It is common for Americans

to wear casual clothing to school and to greet professors by first name.However, good manners and

politeness are always appreciated.If you are polite, and dress a little more formally than your American

friends, it will not be poorly thought of.

     However,some businesses require their employees to wear a uniform or a suit.It would be improper to wear a Tshirt and blue jeans to a job interview.Some of the more prestigious restaurants require a coat and a tie.Americans tend to dress up for cultural events(the opera,theater and ballet)and to dress down for

athletic events.Formal wear is required at weddings and funerals, or any other event with religion.If you

rely on the stereotypes,you will likely put yourself into an embarrassing situation.
