【正确答案】[参考作文]
Dear Dad,
I am having a wonderful time. It is really a good exchange programme. I think I have learnt a lot that cannot be learnt in class. Sue's family are very friendly. They look after me very well and I feel quite at home here. The weather here is very comfortable. Yesterday we visited the Science Museum and did some shopping as well. Tomorrow we are going to Cambridge University. I am looking forward to visiting the university. We will be back to Shanghai on Dec. 31. The plane will touch down at Shanghai Airport at 10:30 a.m. So we will soon meet again. Please give my best regards to Mum and Grandma.
Yours love,
Li Hua
