Dear Tom,
Wish you well.
I am sorry to inform you that I wouldn't be able to accompany you on the trip to Mount Qingcheng as agreed.My brother was going on a camp journey for the summer holidays and I would have to take him to the meeting place with his classmates fifty miles from town.Unfortunately,the meeting date was exactly the same as that of our trip.
I am so sorry that I will have to eat my word,but I will share with you the information I have already gathered about Mount Qingcheng in the next message or upon your arrival.
Many thanks for your understanding.Wish you a good trip.
Yours Sincerely,

亲爱的朋友汤姆：
首先我要先对你说一声对不起，因为今天的约会我大概要失约了。今天许久未见的姨妈来我家做客了，为尽地主之谊，我不得不陪她去四处看看走走。你一定会说为什么不让我的父母去？我的爸爸今天有一个重要的会议，妹妹的幼儿园举行春游，妈妈陪同去了，所以我要失约了，下次一定补上~~就这样，拜~~
