　　Dear Jane,

　　I am terribly sorry to tell you that I have lost the novel you were so kind to lend me last week.I read it every day and planned to finish it next week. However, when I came back home last evening,I couldn't find it.

　　1 will buy a new one for you. But I am afraid it can never replace theold one. Old books are like old friends. Once lost, they can never be replaced. They are connected with cherished associations which the new ones can never have. And for this irrecoverable loss,I feel really sorry.

　　Yours sincerely，

　　Wang Lin

　　The death percentages of different causes in the city during the last three decades have changed significantly. The death percentage by traffic accident has the greatest change from 7% in the 1970s t0 21% in the 1990s,while that of other causes has declined sharply from 38% t0 25%.The other killers-cancer and heart disease-have also increased steadily by 6% and ll% respectively.

　　Thhese changes reflect the development of the city iIl the last three decades. People travel more than they did three decades ago, because they are more engaged in business activities and social communications now. As a result,traffic accidents increase. With better diet and longer life,diseases like cancer and heart attack become bigger killers than other kinds of diseases.
