Dear Xiaoqiang,
I am writing to express my heartfelt gratitude.I am referring to that unfortunate accident the other day,when I was knocked off my bike by a taxi.
If it had not been for your timely assistance in giving me first aid,I fear that the consequences of the accident might have been much more serious.Everyone agrees that it was your quick-witted response in that emergency that has led to this satisfactory outcome.
Although nowadays people talk in mounting numbers about the need to be unselfish,we see very few people who practice what they preach.If there were more people like you,this world would be a much nicer place.
Yours sincerely,
Li Ming
亲爱的小强：
我写信是为了表达我衷心的感谢。我指的是那天我被一辆出租车所撞从自行车上摔下来的不幸事件。
如果没有您及时为我急救，恐怕这场事故的后果会更严重。大家一致认为正是您在那个紧要关头的快速反应带来了令人满意的结果。
尽管现在越来越多的人谈论到大公无私的必要性，但是很少看到有人言行一致。如果有更多人像您一样，世界会更加美好。
您真诚的，
李明
