　　 2017考博英語(yǔ)作文范文：霧霾1

　　Save Energy

　　Water used to be mistaken to be an unlimited and renewable resource. Actually, water resource is very limited and precious. It is fortunate that now the public is starting to pay attention. Just as is depicted in the picture, just like saving money, the lovely and smiling piggy bank is collecting every drop of water falling from the water tap。

　　However, water shortage is still a serious problem threatening the existence and survival of the whole human being, and yet the phenomenon of wasting water can still easily be found anywhere in our daily life. For example, water taps are frequently left on by careless users. Someone even assumes that they have the right to waste water because they pay for it so that it has nothing to do with others. In fact, so precious is water that we cannot afford to waste it. Water resource is indispensable not only in our daily life but also in the industry and

　　agriculture. And water is the wealth of the whole mankind, and it is hard to imagine what the world would be like when there is no more water。

　　Even though an increasing number of people have become aware of this emergency, further measures still need to be taken. On the macro level, the whole world should make a joint effort to fight against waste of water. On the micro level, publicizing activities, such as broadcasting wonderful ways on how to save water on TV and other media, should be conducted. To store water means to store happiness and only by saving water can we save a better life for our offspring。
