     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.
