英文的感谢信
dear mr.wang,
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 might have been much serious. everyone agrees that it was your quick-witted response in that emergency that has led to this satisfactory outcome.
although nowadays people in mounting numbers talk about the need to be unselfish, we see very few people practice what they preach. if there were more people like you, the world would be a nicer place.
yours sincerely,
li ming
