21、A man came back home from work late, tired, to find his six - year - old son waiting for him at the door.

"Daddy, how much money do you make an hour?"

"If you want to know, I make $20 an hour．"

"Oh," the little boy replied, with his head down．He thought for a moment, looked up and said, "Daddy, could you lend me $10?"

The father was furious, "If you asked for money to buy a toy or some other rubbish, then go straight to your room and think why you are being so selfish （自私的）! "

The little boy quietly went to his room and shut the door．After about an hour or so, the father calmed down, and started to think, "Maybe he really needs to buy something and he didn' t ask for money very often" So he went to the little boy' s room.

"Sorry! Maybe I was too hard on you just now," said the man．"Here' s $10．"

"Oh, thank you, Daddy!" the boy said gladly．Then, the hay took out some coins．When the father found that the boy already had some money, he got angry again.

"Why do you want more money since you already have some?" the father shouted angrily.

"Because I didn't have enough, but now I do, "the little boy replied, "Daddy, I have $20 now．Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you."

20、Many children love to play with snow in winter．But Long Chuan has come to hate it.

This year his hometown suffered from snowstorms （遭受暴風(fēng)雪） for nearly a month．The heavy snow stopped cars and trains, broke the electricity （電） tower and turned tap water to ice.

Every day Long Chuan had to walk several kilometers to carry drinking water．"I couldn’t' t ride a bike and it took me 3 hours to walk to school．I can' t remember how many times I slipped（滑到） on the hard ice, "said Long Chuan.

Long is not alone．This year millions of people in central and southwest China had a freezing winter without enough water and electricity．The biggest snowstorms in 50 years killed more than 100 people．They also cost the country 111.1 billion yuan.

Experts （專家） say a special type of climate condition （氣候條件）, La Nina, caused the storms．During a La Nina, the water in the Pacific Ocean （太平洋） near the equator （赤道） becomes colder than usual．It changes the weather around the world.

Besides China, Canada, the US and Middle Eastern countries also met with heavy snowstorms this winter．The special climate caused the recent flooding （洪水） in Australia, too.

However, experts say that people have destroyed the environment （環(huán)境）．Global warming （全球變暖） may be causing these terrible weather events to happen more and more often.

19、If you knew a bottle of water had been recycled from urine （尿）, would you drink it? Astronauts at the International Space Station （ ISS ）may soon do so.

NASA （美國航空航天局）said it would use a high -tech machine （高科技機(jī)器） to recycle wastewater at the ISS．The machine will recycle everything from sweat （汗）, the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water．It will save NASA millions of dollars each year．At present, each ISS astronaut uses about 4.4 liters （升）of water every day．It costs about $24 million a year to transport water up to ISS．NASA says that a liter of water costs about $11,000.

The machine will be sent to the ISS in October 2008．NASA hopes it will recycle about 93% of all water used on the station.

Will the water be clean? Scientists say the wastewater will go through a very complicated process （復(fù)雜的過程）．For example, different chemicals will be put in the wastewater; the water will be heated to 130℃ to get rid of bacteria （細(xì)菌）．The recycled water is thousands of times better than the water from a city tap, scientists say.
