根据上文内容判断正 (T) 误 (F)。

     Mrs Jones' telephone number is 2562781 and the number of the city cinema (市影院) is 2562718.

Because the two numbers look the same, some people often make a mistake (弄错) and telephone her

when they want the cinema.

     One evening, the Jones are having supper at the table. Just then, the telephone bell rings (铃响). Mrs

Jones goes to answer the telephone. A tired (累的) man says," Excuse me, at what time does your last

movie begin?"

     "I'm sorry," says Mrs Jones," But you have the wrong (错误的) number. This is not the cinema."

     "Oh, sorry, it began twenty minutes ago (以前)? Thank you all the same. Goodbye." Says the man.

     Mrs Jones is very surprised (惊讶), so she tells her husband (丈夫) the whole thing. Her husband,

Mr Jones laughs (笑) and says:" I see. The man's wife wants to go to a movie, but he is tired. He doesn't

want to go to a movie. So he telephones the cinema. His wife hears (听见) him, but she can't hear you.

Now they stay at home this evening, and the husband is very happy and he can have a good rest (休息)

at home."
