Dear Sir，

Thank you for your offer of invite me to the summer English course in your school. As for your choice between the two courses, I prefer the four-week course for 60 hours of study. Because of this would allow me more times to do some travelling and make a few new friends either. Of all the subjects I'm learning at school, I like English best. I had been learning English for 6 years but my spoken English remains poorly. So I hope to take this chance to improve it. If is possible, I'd like to stay with a family for a couple of days in order I can know some customs in England. I believe I will have wonderful time this summer.

Yours truly,

Li Hua

I had a interesting dream last night. I dreamed that I took part in a race. At first, I could not to run very fast and fell behind. So I didn't lose heart and kept running. All the students on the playground cheer me on," Come on!” I was so encouraged that I ran faster and fast till I caught up all the other runners. I felt as if flying like a superman. In the end, I get to the finishing line first. I won the race. I felt very proudly of myself. Many of my classmate threw me up into the air. Just at that time I woke up and found me still in bed!

    Last Saturday I went to the library as usually. At about noon, I was enjoying my reading near a lake while suddenly I hear someone crying for help. I went up to see what was happened. I was shocking to find a little child struggling in the water in the distance while many peoples were standing by without doing anything. Without any hesitation, I had pushed through the crowd as I took off my coat, but jumped into the water quickly. I managed to reach him and carried him back to safety. To his great relief, the kid was saved.

    I was proud what I had done. I hope everyone can give a hand when someone else is in need.

    Writing was my favorite class at school. My teacher, Bebe Usi, was devoting and encouraging. We each spent several classes make a paper mask and wore it when reading our own work before the class. I have forgotten that composition now, but I remember the feeling of mask on my face and my heart was beating wild as I shared my composition. I was afraid of but proud. I have written many compositions before that but none of which had been chosen to be read before the class. They perhaps weren't the best composition and the most beautiful mask in my class. But they both were my.

    Today we went to the beach. We get up early and after a 2-hour bus ride, we arrived. Lucky for us, there was not many people there yet. The sky was blue but the sun was shining. The water was so clear!

    We all swam in the sea and had good time. I did not dare to swim very far because I was afraid of be carried away by the ocean.

    Before the swim, we lay on the beach. Bill hid both of his leg in the sand, which he thought it was very funny. It was a great day. I'll ever forget it.
