Dear Aunt
I am very happy to receive your letter. Now let me tell you something about my school life and study.I am now in Grade Nine.I know I will have Senior high school entrance examination in less than a year. So I work hard every day and do exercise for about an hour at school. We have at least nine classes every day so you can imagine how tired we are. After school I have a lot of homework to do and I also like to preview the lessons in the evening. I want to enter a good senior school in the future so I do not go to bed until 11:00. I know if I work hard, my dream will come true. That's all. I have to go to study. Take care.
Yours
Wang Lei
junior nine听着好别扭,直接九年级吧.
高考是College Entrance Examination, 中考就应该是Sinor high school entrance examination没错.
how hard we are用hard形容人不大好,要不就说hardworking
not...until才表示“直到……才……”
