How to save water
We can never over emphasize the importance of saving water. But we are now wasting a large amount of water in our daily life.
It’s estimated that about 70％of the water used in a family can every day can be saved if we follow the tips below. First, use recycled water. For example, you can use the water to wash rice first, and then use it to wash vegetables, and finally the water can be used to wash the toilet. Second, when you are taking a bath, turn down the tap a little bit. Remember to shut it off in time if you are not using it. Third, when you are washing dishes, use some paper to clean them first, and then use the water to wash them, which will save much water.
Only when everyone takes an active part can we really help save our limited water source.
試題分析：本文是材料和圖表結合的`作文，通過認真讀題，我們明白了寫作要求和目的。本文要求說明節約用水的重要性；提出節約用水的具體方法；發出號召。應該用第二人稱，時態以一般現在時為主。寫作前最好先根據給出的提綱，寫出有關的短語和固定表達備用。最后串聯起來。
【亮點說明】 本文做到了包含所有內容層次清楚，語句通順，標點符號運用正確。在100詞左右的篇幅中，恰當地運用了一些短語和句式，如It’s estimated that…和when引導的狀語從句，which引導的定語從句，尤其是最后，only加狀語句子倒裝都是較高級的表達。還有recycled ，in time等比較高級的詞匯都可圈可點。
