写给朋友小林的一封信，谈谈寒假生活。
1．寒假很忙，因为今年七月要参加高考。
2．每天埋头读书，复习每门必修课，做许多练习。
3．学习刻苦，每天学习10小时以上，累时看会儿电视，听音乐，但总不去影剧院。不得不回绝亲戚朋友的邀请，只在除夕时打电话问候。
4．多希望没有考试，但又不可能，要尽力取得好成绩。考上渴望已久的清华大学。
参考词汇：
必修课：required subject
埋头于某事：bury oneself in sth .

参考范文

Dear Xiao Lin,

    I have had a busy holiday these winter because I will take part in the entrance examination this September.

    I almost buried myself in the books every day. I had to go over every required subject and did a lot of exercises. I worked very hard, more than 10 hours a day. When I was tired I watched TV for a while and listened to music, but I never went to the cinema or theater. I had to refuse several invitations from my relatives and classmates. I only called them to greet them on the eve of the Spring Festival. How I wish there were no examinations at all, but of course it is impossible. I will try my best to get better results and go to were no examinations at all, but of course it is impossible. I will try my best to get better results and go to Qing Hua University, which I have been longing for. How is your vacation? Best wishes to you and your family!

Yours
Wu Qi
