How are you doing? You asked me in your last letter about my plan for the coming summer vacation. I am sorry that I didn't reply without delay. How I wish I would read and reply your email as soon as I received it. However, I was busy preparing for my final exam at that time, which is vital for me. As a result, I had no choice but to completely focus on my study, for which I am very sorry. I hope you can understand me.
During the holiday, I am going to do a part-time job. On the one hand, I can earn some money to reduce the burden of my family. On the other hand, I accumulate the social experience, which does good to my future life. At the same time, I will not forget to go over my lesson. I will spend a instructive holiday. How will you spend your holiday? I hope you have a good time.
These are my plan for the summer vacation. What's yours? I am looking forward to your earliest reply.
