根据短文内容判断下列句子的正误，正确的用“A，错误的用“B

     People usually hate(憎恨)  mice,  but one mouse has won the hearts of the people all over the world

--the famous Mickey Mouse.

     Fifty years ago most movies were silent(无声的). A man called Walt Disney made a cartoon mouse

that could talk in his movies. He named his mouse Mickey Mouse. Both young and old people were very

excited at the talking mouse. Children loved to see him, because he brought joy and laughter to them.

     Mickey was a clean mouse right from the beginning. Perhaps this is one reason why pepole love him.

In his early life Mickey made some mistakes. People were angry. They wrote to Disney and said that they

did not want Mickey to do silly(愚蠢的) things. So Disney made a new animal named Donald Duck.  He

also made a dog called Pluto. This dog does silly things and makes mistakes wherever he goes.  Now our

Mickey Mouse is not only clean but also important. He appears as a beautiful and clever star. He has his

friends in almost every country.
