Dear Tom,
How are you doing? You (ask) me in your last letter about my plan for the coming summer vacation．
I am sorry that I didn’t reply delay．How I wish I (read) and reply your email as soon as I received it．, I was busy preparing for my final exam at that time,is vital for me．As a result, I had no choice but(focus) on my study completely．I believe that if you(be) me, you would make the same choice。
By the way, I have a busy schedule for my summer vacation．First and foremost, I would do a part time job, so that my interpersonal skills(improve)．Additionally, I will take a short trip to Beijing to take a summer course in the New Oriental School．Last but not(little), maybe I will work as a volunteer for the school as a teaching assistant．
These are my plan for the summer vacation．What’s yours? I am lookingto your earliest reply．
