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 (美国航空航天局) said it would use a high-tech machine (高科技机器) 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 (复杂的过程). For example, different chemicals will be put in the wastewater; the water will be heated to 130℃ to get rid of bacteria (细菌). The recycled water is thousands of times better than the water from a city tap, scientists say.
1. NASA will use a high-tech machine to recycle wastewater at the ISS to __________.
A. protect the ISS

A. freezing B. heating C. shaking D. precipitating (沉淀)

If you knew you had only three years left to live, how would you use your time? It’s a hard question and few of us would even like to think about it. But 18-year-old Huang Ge has to answer this question and he says, “I want to thank the people who have helped me.”
At the age of one, Huang’s mother left the family. Six years later, he was badly ill. He has been using a wheelchair（轮椅）since 9 years old. Doctors said he would only live to be 18.
After Huang’s story went on TV, hundreds of Chinese sent money to help him. The boy was so moved （感动）that he decided to thank everyone of them. But it is not an easy job, because Huang was too sick even to drive a mosquito(蚊子) away from his leg. Huang has to be tied（系）to his wheelchair to stop him from falling out.

| At eighteen, I left my home and studied history at Leeds University in England. It was a hard time in my 1 as I was learning to deal with the pain of my father's recent death. One day at the market, I saw an elderly gentleman having difficulty holding onto both his walking stick and his bag of apples. I rushed over and 2 him. "Thanks. Don't worry, I'm quite all right now," he said, smiling at me with a pair of bright eyes. "May I walk with you?" I asked and so began my friendship with Mr Burns, a man whose 3 and warmth very soon came to mean a great deal to me. When we arrived at his house, I insisted on helping him prepare for his meal and asked if it would be all right if I came back again. I thought I should help him. With a smile he replied, "I've never been one to 4 an offer from a kind-hearted girl." I visited Mr Bums twice a week, always on the same days and at the same time. I told Mr Bums how regretful I felt about being 5 with my father two weeks before his death. After about a month, when I went to his house at a different time, I saw him working in his garden, moving around 6 . I was very surprised. "How?" I began, "I thought…" "I know what you thought. When you first saw me at the market, I hurt my ankle earlier that day." "But…when were you able to 7 normally again?" "Ah, not long after our first meeting." "But 8 ?" Iasked. "When you came around for the second time, I saw how unhappy you were, feeling 9 and sad. I knew you were telling yourself that you were visiting me for my sake and not your own. I didn't think you would come back if you knew I was 10 , and I knew you really' needed someone to talk to, and someone who knew how to 11 ." Mr Bums, the man I'd set out to help, helped me. He gave the gift of his time and kindness to a young girl who needed 12 . | ||||
