     Mr. and Mrs. Smith had always spent their summer holidays in New Jersey in the past, staying in a small

inn (旅馆) at the foot of a hill. One year, however, Mr. Smith made a lot of money in his business, so they

decided to go to London and stay at a really good hotel while they went touring around that famous city.

     They flew to London and arrived at their hotel late one evening. They expected that they would have to

go to bed hungrily, because in that small inn in New Jersey, no meals were served after seven. They were

therefore surprised when the man who received them in the hall asked whether they would take dinner there

that night.

     "Are you still serving dinner?" asked Mr. Smith.

     "Yes, certainly, sir," answered the man, "We serve it until half past nine."

     "Well, sir," continued the man, "We serve breakfast from seven to half past eleven in the morning, lunch

from twelve to three in the aftemoon, tea from four to five, and dinner from six to half past nine."

     "But that hardly leaves any time for us to see the sight of London!" said Mrs. Smith.
