The summer vacation is over. It's true that time always flies fast. During the vacation, the weather was hot and I could not do much work, but I lived happily.
As the afternoon was hot, I did my work in the morning. I used to get up at 6:30 and take a walk in the garden for half an hour. After breakfast, I began reading English and Chinese and did some exercises in math. Those took me three hours or more. I worked quite hard and made good progress.
I spent the afternoon outside. I went to swim and it was funny. I would not go home until it was about five or six o'clock. Sometimes a friend of mine would come to see me and we would spend some hours listening to music.
In this way I spent my vacation happily. And I not only studied well but also became a good swimmer. Now I am in good health and high spirits.

Dear Linda,
I have been in England three months now. I hope you don't think I've forgotten you. There have been so many places to see and so many things to do that I've not had much time for writing letters.
I shall soon be starting my studies at King's College. So far I've been learning about England and British ways of living. I won't tell you about London. There are plenty of books you can read and plenty of pictures you can look at. I'm sure you'll be more interested to know what I think about the life here.
I find some of the customs new and interesting. People here do not shake hands as much as we do in Europe. During the first few weeks I was often surprised because people did not put out their hands when I met them. Men raise their hats to women but not to each other.
Yours
Alice

An old lady in a plane had a blanket(毯子)over her head and she did not want to take it off. The air hostess spoke to her, but the old lady said, “I have never been in a plane before, and I am frightened. I am going to keep this blanket over my head until we are back on the ground again!”
Then the captain came. He said, “Madam, I am the captain of this plane. The weather is fine, there are no clouds in the sky, and everything is going very well. ”But she continued to hide.
So the captain turned and started to go back. Then the old lady looked out from under the blanket with one eye and said, “I am sorry, young man, but I don't like planes and I am never going to fly again. But I'll say one thing,” She continued kindly, “You and your wife keep your plane very clean!”
