If you have a bottle of water recycled from urine(尿), would you drink it? Astronauts at the ISS may soon do so.
NASA(美國航空航天局)said it would see a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria. Scientists say that the recycled water is thousands of times better than the water from a city tap(水龍頭).

John H. Johnson was born in a black family in Arkansas City in 1981. His father died in an accident when John was six. He was reaching the high school age, but his hometown offered no high school for blacks.
Fortunately he had a strong—willed caring mother. John remembered that his mother told him many times, “Son, you can be anything you want really to be if you just believe.” She told him not to depend on others, including his mother. “You have to learn success” she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
These words, came from a woman with less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son, who was then 15, to Chicago.
Chicago in 1933 was not the promised land that black southerners were looking for. John’s mother and stepfather could not find work. But here John could go to school, and here he learned the power of words--as an editor of the newspaper and yearbook at Du Sable High School. His wish was to publish www..coma magazine for blacks.
While others discouraged him, John’s mother offered him more words to live by “Nothing beats a failure but a try.” She also let him pawn(典當(dāng)) her furniture to get the $ 500 he needed to start the Negro magazine.
It is natural that difficulties and failures followed john closely until he become very successful. He always keeps his mother’s words in mind:” Son, failure is not in your vocabulary!” Now John H. Johnson is one of the 400 richest people in America--worth $150 million.
What does the story mainly want to show us?
A. The key to success for blacks.
B. The mental support John’s mother gave him.
C. The importance of a good education.
D. How John H. Johnson became successful.
Why did John’s mother decide to move to Chicago?

B. Because life was too hard for them to stay on in their hometown.
C. Because John needed more education badly.

A. John’s mother didn’t believe in or depend on others.
B. John’s mother believed one would succeed without working hard.
C. John’s mother thought one could be whatever one wanted to be.

John H. Johnson was born in a black family in Arkansas City in 1918. His father died in an accident when John was six. He was reaching the high school age, but his hometown offered no high school for blacks.
Luckily he had a strong-willed caring mother. John remembered that his mother told him many times, “Son,you can be anything you want really to be if you just believe.” She told him not to depend on others,including his mother. “You have to earn success,” she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
These words came from a woman with less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son, who was then 15,to Chicago.
Chicago in 1933 was not the promised land that black southerners were looking for. John’s mother and stepfather could not find work. But here John could go to school, and here he learned the power of words — as an editor of the newspaper and yearbook at Du Sable High School. His wish was to publish a magazine for blacks.

The Centers for Disease Control and Prevention says that over 50,000 people every year sustain some sort of winter-related back injury, and 5,800 of those are holiday decorating-related. These aches and pains can __41__ bring trouble to people’s life. It is said that people’s back could sustain all sorts of strain from carrying heavy __42__ , and from the increased stress of lugging suitcases, decorations and gifts. Dr. Alanna Levine spoke to Debbye Turner Bell on “The Early Show” about how to protect the back for the holiday season.
The first tip Dr. Levine gave was about carrying heavy shopping bags. Smaller bags, she said, are better. “You don’t want to load everything up into one bag and lug it around,” Dr. Levine explained. “You want to __43__ the weight on your body.” She also recommended putting heavier items towards the bottom in those bags and lighter items on top. Also, if you can, make __44__ trips to the car to drop off purchases.
