People from Great Britain brought the English language to North America in the 16th and 17th centuries. And in the  36  300 years, there were  37  many changes in  38  places that now people can  39  tell an English person  40  an American in the way he or she talks.

Many old words  41  in England but were kept in America. For example, 300 years ago people in Great Britain got their water from something they called either a

“faucet”, a “spigot”, or a “tap”. All these words are  42  heard in different parts of America, but only “tap” is still common in  43 . Americans often made up new words or changed old  44 . “Corn” is one kind of plant in America and  45  in England.

Also, over the last three centuries the English language  46  thousands of new words for things that weren’t known  47 . And often, American and English people used two  48  names for them. A tin can (洋铁罐头) is called “tin” for short in England, but a “can” in America. The word “radio” is  49  all over the world, including America. But many English people call it a “wireless”. And almost anything having something to do  50  cars, railroads, etc.  51  different names in British and American English．

But now American and British English may be growing closer together. One  52  is the large amount (数量) of American speech that British people hear daily in movies, on television, or  53  travelers.  54  this, Americans seem to be influencing (影响) the British more and more. So some day, English may even be  55  on both sides of the Atlantic (大西洋).
