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 am the senior student. I appreciate make friends with people and I do my best to be on good term with everyone. But in last week I found that one of my friends told another classmate, saying that she disliked me and that she doesn't want to be my friend any longer. And by now she started playing a trick on me although I'm fat. I'm kind to him but why can't she be friend to me? As for losing the discouraged weight, should I don more exercise? Use pills? And do you know any other ways? Please give me some advice.

    It was March 8th, Women's Day. I decided to do something for my mom and give her a surprise.

    Immediately after school, I went to the supermarket, when I bought plenty of vegetables, fish and meat. As soon as I arrived home, I started to prepare the dinner for Mom. It was the first time that I had cooked something on my own. Not knowing the exactly process to cook. I read some recipes first. Keep what I had learned in mind, I got down with cooking. Almost an hour later, three simple but delicious dishes were ready on the table.

    Since Mom couldn't get home until thirty minutes later, I started to do some cleaning. It was not difficult for me. Mopping thoroughly , the floor was quite clean.

    No sooner had everything been ready Mom came back. I couldn't wait to show what I had been done for her. A big smile with both surprise and satisfy spread on Mom's face when she found the hearty（丰盛的）dinner and the tidy room. At that moment, pride rose from a bottom of my heart. Although she fell a little tired, everything was worthwhile.
