Dear Bob,
I am writing to express my apology to you.
Several days ago, I borrowed your music CD when I lived in your house. Unfortunately, after I came back from Canada, I found it in my luggage. I was in such a hurry that I forgot to return it to you. I will send it to you by post or express as soon as possible. If necessary, I will compensate for any troubles it may cause.
Once again, I feel so sorry for any inconvenience caused. Please accept my apologies                                                     
Sincerely yours,
Li Ming

大作文范文

As is illustrated in the picture, the two disabled persons whose crippled legs are bound together do a lot of traveling. Accordingly, this far-reaching picture reflects a common phenomenon in today’s society: the people who are in the dark want to turn the corner but they can not make it respectively and in turn they have to choose to pull together in times of trouble.
There are several reasons accounting for this. Since we have to live in an on-the-move lifestyle, we may encounter various plights, where we would be at a loss rather than to seek for others’ assistance. Further more, if we do not offer help to each other when we confront dilemma, we would not realize our dream. And no issue in China is as basic to build up the society in harmony as to conduct coordination in face of disasters.
Judging from what have been argued above, people have come to realize the value of mutual aid. It is, therefore, necessary that some effective steps be made to advocate spirit of supporting each other. To begin with, the government should make laws to encourage people to unite. In addition, people should enhance the awareness of caring each other especially when they are in trouble. Only in those ways, can we make people, even not being acquaintance, help each other.
