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 used to delay things until deadlines, that caused me much trouble. Therefore, I thought of some ways to get rid the bad habit. First, I took a shower right after I got home from school. It refreshed me but made my thoughts more active. Furthermore, in order to avoid being continual disturbed by my cellphone, I left them with my parents. The final strategy I use was scheduling. I managed to planning my days ahead of time so that I could break up my tasks rather than having too many work to do on the last day. By using these simple technique, I've improved my efficiency and made a good use of my time.

    Is it necessary to practise handwriting? Some students consider handwriting least important than before. They preferred the keyboard to the pen now, for the former is fast, convenient and clear. They think it is waste of time practising handwriting. However, others think Chinese handwriting is an important part of our traditional culture.

    Though computers are very convenient, but handwriting still plays an important role in the modern world. Beside, beautiful handwriting makes a good impression in others. It shows your attitude to do things. Chinese character are very beautiful and rich in culture. As for me, when reading a neatly writing article, you will feel pleased and relaxed.
