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.
我們都知道水對於日常生活的重要性。我們每天喝水，用水洗東西和烹製食物，我們還用水來製造機器。離開水，人類就無法存活。
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。所以我們應該用淋浴代替泡澡來節約水，同時及時修好滴水的水龍頭，並且不要開著水龍頭洗東西。
