Dear Mark,

I’m very glad you are so interested in our school.

Recently our school is launching an activity to call for thrift and go against wasting. Every student is required to save paper, water, electricity and food. All waste paper must be collected and sold to help the poor students. Water must be made full use of and now you cannot find any tap that is left running without students around. And each student should get into a great habit of turning off the light on time. What’s more, all of us are called on not to use our pocket money to buy some things unnecessary and some students even use their saved money to help the students in need.

Yours,

Li Hua

题目分析：这是一篇话题类作文。假如你是李华，你的外国笔友Mark 想了解你校的近况。正好你校正在开展“提倡节约、反对浪费”的活动。 请根据下文的提示给Mark写一封电子邮件。节约用纸，废纸回收；节约用水，珍惜水源；节约用电，按时熄灯；节约用餐，不乱花钱。需要写的内容已经粗略给出，需要我们翻译成完整通顺的句子，适当添加些内容，使文章更充实。写作时注意准确运用时态，上下文意思连贯，符合逻辑关系，不能出现文章脱节问题。一定要给出自己的看法。尽量使用自己熟悉的单词句式，同时也要注意使用高级词汇和高级句型为文章润色。注意要求的词数100词左右，不要太多也不要太少。

【亮点说明】Water must be made full use of and now you cannot find any tap that is left running without students around.这里含有一个定语从句。
