水是生命之源 Water is the Source of Life

Water is very important. It is the source of life. Everything in the world can’t live without water. The proportion of water and a person’s weight is about 70%. People can live without eating food for three days, but they will be very close to death if they don’t drink water for three days. The same goes for other creature. What’s worse, without water, everything will be stop. We can’t have power, and the world will be in the darkness. The parts of cell phone can’t be made. Then we have no way to connect with others. In a word, water is pretty significant. We need to protect it and save it.  
水非常重要。它是生命之源。世界上的所有東西都離不開水。人體內的水分和體重的比例大概是70%。人們可以三天不吃食物，卻不可以三天不喝水。同理可證，對於其他生物也是一樣的。更糟的是，沒有水，萬物都會停止了。我們無法發電，世界即將陷入黑暗中。手機的零件無法造成。我們就沒辦法與其他人聯繫。總之，水是很重要的。我們需要保護它，節約它。
