Water was pouring into the washbasin and vanishing down the drain.Read5-112345Who are you?5-212345‘Turn that tap off,’ a voice said loudly. Daisy froze. She looked around, but saw no one. ‘Turn that tap off. You’re wasting water!’ The voice sounded impatient.
This time Daisy obeyed. ‘Who … who are you?’ Daisy’s voice was faint.
‘I’m a drop of water. It’s not easy for me to get here. Do you know where I’m from?’
‘From the tap, I suppose,’ said Daisy.5-312345‘Yes, but before that?’ Water said. ‘A few days ago, I was floating comfortably in a cloud in Jiangxi, enjoying the view. Then the cloud dropped me into a stream and I sped down the mountain into the Yangtze River. The Yangtze River carried me to a lake. I relaxed there for a few days, and then I travelled a long way and ran into the Huangpu River. Then it was time to get cleaned up.’
‘Cleaned up?’ Daisy sounded puzzled.5-412345‘Yes. I was dirty after my journey so they took me to a water treatment works. They gave me a thorough cleaning and added a few chemicals to me. Then I travelled in the pipes under the streets. I waited there until you called me, and here I am.’
Daisy said, ‘So this is the end of your journey.’
‘No. When you’ve finished with me, I’ll go to a sewage plant. Then they’ll pump me into the river and I’ll be back in the sea again.’
‘Again?’5-512345‘Yes. That’s where I came from in the first place. Remember not to waste me or pollute me. I’m precious, like liquid gold. See you.’
‘Wait a minute. What do you mean by liquid gold?’ But there was no reply. The water had gone.
Daisy came out of the bathroom. Her brother said, ‘Who were you talking to?’
‘I was talking to the water,’ Daisy said.
‘Sometimes you’re strange, Daisy,’ her brother said.ConsolidationWorkbook 8B, page 9.

You’re wasting precious time! People can live without food for more than a month, but they can’t live without water for more than a week. Losing more than 20% of the normal water content of our bodies will result in a painful death.About 65–70% of our bodies is water, so it is important for us to drink a lot of water. Each day, a normal person will drink about 2.4 litres of water or other drinks.You need more water during and after exercise because you lose water by sweating and you need to replace the water that is lost.Water freezes at 0oC (32oF). When it freezes, it changes into ice. Water boils at 100oC (212oF) when it changes its form into a gas, becoming steam.Water covers 70% of the Earth’s surface, but only about 3% is fresh water. All the rest is salt water. Of this 3%, less than 1% is in the form of lakes or rivers. The remaining 2% is frozen in glaciers at the North and South Poles.‘H’ stands for hydrogen and ‘O’ stands for oxygen. The symbol means that each water molecule consists of two atoms of hydrogen and one atom of oxygen.
