As we all know, water is essential in our daily life. We drink water every day, we use water to wash things and cook food, we also use water to make machines. People can't live without water.

　　我們都知道水對(duì)于日常生活的重要性。我們每天喝水，用水洗東西和烹制食物，我們還用水來(lái)制造機(jī)器。離開(kāi)水，人類就無(wú)法存活。

　　Though about 75% of the earth is covered with water, only 3% of it is fresh water. So we must save water by having a shower instead of a bath. We can save water by fixing dripping taps immediately and we can also save water by not washing under a running tap.

　　雖然地球75%都被水覆蓋，但其中只有3%是淡水。所以我們應(yīng)該用淋浴代替泡澡來(lái)節(jié)約水，同時(shí)及時(shí)修好滴水的水龍頭，并且不要開(kāi)著水龍頭洗東西。
