第二节  书面表达 (满分35分)

每年的10月31日是联合国确定的“世界勤俭日”。假设你是李华,你最近给你在美国的朋友Mike的一封e-mail中专门讨论了“勤俭”的问题。你的e-mail内容应包括: 1)指出校园内中学生花钱如水,没有节约的概念。 2)分析产生这一现象的原因(独生子女;生活水平的提高;追求时髦) 3)你对“节俭”的看法。

注意:

1、字数:110左右。

2、开头和结尾已写好,不计入总字数。

3、参考词汇:世界勤俭日:World Thrift Day; 花销:expenditure; 现象:phenomenon; 奢侈:extravagance(这个提示不要为好,范文中并未用到,有了反而增加了难度)

Dear Mike,

   How’s everything going?

As you know, World Thrift Day falls on October 31. So this time I’d like to discuss thrift with you. In recent years, the monthly expenditure of middle school students has been on the sharp rise._________________________________________

How about your point about thrift?

Best wishes!

                    Yours faithfully

                        Li Hua
