     Mr and Mrs Smith had always spent their summer holidays in New Jersey (新泽西) in the past, staying
in a small inn (旅店) 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 had expected that they would have
to go to bed hungry, because in that small inn in New Jersey, no meals were served after seven. They were
surprised when the waiter asked whether they would take dinner there that night. "Are you still serving dinner?"
asked Mr Smith. "Yes, certainly, sir," answered the waiter. "We serve it until half past nine."   
     "What are the times of meals then?" asked Mr Smith. "Well, sir," answered the waiter. "We serve breakfast
from seven to half past eleven in the morning, lunch from twelve to three in the afternoon, tea from four to
five, and dinner from six to half past nine."   
     "But that hardly leaves any time for us to see the sights of London." said Mr Smith.

Dear Mrs Winthorp,

So my first week at college is over! No lectures this morning so think I’d email you and let you know what things are going.

I’m glad to say that anything has worked out fine in the dorm. I remember asking for a room as far away from the lifts as possible and they find me a comfortable one on second floor. There are two girls from my course here and I plan to make friend with them so that we can help each other on the course work. Everyone else seems very nice and warmly here.

Well, I had better to stop now. I’m going to attend mine first lesson this afternoon ,for I’ve got some preparation to make .Keep in touch.

Best,

Carol
