in the future.
Yours truly,
亲爱的[弗兰克]：
很抱歉，[上星期]您借给我的那本书竟遗失了。我[每天]都在看，准备[下个月]看完。[昨晚]我回到我的卧室，到处也找不到那本书。我将尽力找到它。万一找不到，我只好买一本新的还您。
但是，新书恐怕不能代替那本旧书吧！旧书跟旧友一样，一旦失去就不能再得。旧书与往事相连，这种不可弥补的损失，皆由我起。我对待一切太大意了，这次给我一个警告，叫我以后要小心。
三、慰问信
慰问信应写得真切，注意措辞，对轻病或者小损失，慰问信应写得轻松一些。相反，对严重病情或重大损失，信就应该写得深沉一些。慰问信写时应注意：
1. 写给受伤人的信要简短，中肯。信中不必问询事故发生的过程、原因、见证人等。
2. 慰问信中应写一些被慰问者喜欢或熟悉的事物，如病人的爱好、兴趣等，以使病人得到宽慰。
1. 向朋友问候 A letter of inquiring after someone’s health
Dear [John]:
I am extremely sorry to hear that your illness, which we had thought was clearing up, has become more serious, and that your have had to go into hospital. Let us hope that it will be for only a very short time, and that you will soon be out and about again. Everybody here sends his best wishes to you for a quick recovery.
With kind regards,
Yours sincerely,
亲爱的[约翰]：
听说你病了，我深感不安。原来我们还以为您的病情有所好转，事实上却反而加重，而不得不住进了医院。但愿这是短时间的，很快不会恢复健康。这里每个人都祝愿您早日痊愈。
