【正确答案】[高分范文]
Dear Alex,
I am so glad to hear that you are going to study in Hangzhou for a month. We eventually have the opportunity to see each other and I could not wait to meet you in China!
The weather will be quite comfortable in April, with the average temperature of 20 degree celsius. It will be a good time to stay outside and visit places of interest in Hangzhou. Therefore, do not forget to bring your camera! I bet you will be deeply impressed by the beautiful scenery in Hangzhou. Also Hangzhou will be quite humid at that time. Bring your umbrella with you in case we get caught in the rain.
I am looking forward to your coming. Wish you have a nice trip in advance!
Yours sincerely,
Li Ming
