Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had been recycled from their urine(尿), sweat and water got from air. They said “cheers,” clicked drinking bags and toasted NASA workers on the ground.
The urine recycling system is needed for astronaut stations on the moon and Mars. It also will save NASA money because it won’t have to ship up as much water to the station by space shuttles or rockets. Besides, it’s important as the space station is about to expand from three people living on board to six.
The recycling system had been brought up to the space station last November by space shuttle Endeavour, but it couldn’t be used until samples(样品) were tested back on earth. So when it came time to actually drink up, NASA made a big deal of it. The three-man crew stood holding their drinks and thankedengineers in two NASA centers that worked on the system.
“This is something that had been the stuff of science fiction,” American astronaut Michael Barratt said before taking a small mouthful. “The taste is worth trying.”
The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the steam is collected. The rest of the urine is thrown away. Then the water steam is mixed with water from air, and then it goes through filters (过滤器). When six crew members are aboard it can make about 18 liters from urine in about 6 hours.
“Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with a lot longer time between urine and the tap,” said Marybeth Edeen, the space station’s national lab manager.
The technology NASA developed for this system has already been used for quick water purification after the 2004 Asian tsunami. According to the text, the recycling system is important because __________.
A.it makes traveling to the moon for the average person possible |
B.it can help meet the need for more water after the crew is expanded |
C.with it NASA won’t need to ship any water up the space station |
D.it protects the environment in space by reducing the amount of waste |

Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?
To see whether babies know objects are solid. T. Bower designed a method for projecting an optical illusion (视觉影像) of a hanging ball. His plan was to first give babies a real ball, one they could be expected to show surprise in their faces and movements. All the 16 to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land (想像中的地方)?
Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to re-appear. If the experiment took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted (替换) a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week-old babies did not seem to notice the switch (更换). Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object.The passage is mainly about ______.
A.babies’ sense of sight |
B.effects of experiments on babies |
C.babies’ understanding of objects |
D.different tests on babies’ feelings |
. In Paragraph 3, “object permanence” means that when out of sight, “object ______”.
A.still exists | B.keeps its shape | C.still stays solid | D.is beyond reach |
. What did Bower use in his experiments?
A.A chair & a screen | B.A screen & a train | C.A film & a train | D.A box & a chair |
Which of the following statements is true?
A.The babies didn’t have a sense of direction. |
B.The older babies preferred toy trains to balls. |
C.The younger babies liked looking for missing objects |
D.The babies couldn’t tell a ball from its optical illusion. |
Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first taste of beer. Feeling sick, wasn’t it? When my father gave me my first try of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (attraction) that you need your will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to such experiences, can ever someday come to develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, just in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.What do most people think causes bad behavior?
A.Being forced by others. |
B.Not having enough will power. |
C.Enjoying their first experiences. |
D.Following the examples of their friends. |
The author mentions his experience in the third paragraph to prove ______.
A.will power helps develop bad habits sometimes |
B.drinking beer is harmful to the health of teenagers |
C.self-control should be developed when one is young |
D.everyone can be challenged by different temptations |
In the last paragraph, the author stresses (强调) that ______.
A.without self-control, no one can succeed |
B.bad habits don’t always lead to bad results |
C.applying self-control correctly is important |
D.people can develop wisdom from bad behavior |
What would be the best title for the passage?
A.My First Taste of Beer | B.Do You Have Will Power? |
C.Will Power Benefits Us | D.Dark Side of Self-control |

February 4, 2012 saw the take-off of a new rising NBA star-Jeremy Lin.
Among professional basketball players, Jeremy Lin's background is not typical. He graduated from Harvard University, which sends few players to the NBA, and he is the only Chinese-American NBA player.
Lin's enjoyment of basketball actually began in Taiwan. When Lin's father moved to U.S., his interest in the sport only grew and he passed on this love of basketball to his son, introducing him to the game at the age of five. The young Lin spent much of his youth playing basketball for fun.
In high school, Lin dreamed of playing in the NBA. When he applied for college, he was not offered a single sports scholarship. However, after his admission to Harvard, he was offered a place on its college basketball team.
During Lin's time at Harvard, his basketball career began to speed up. He scored 1,482 points, making him one of the highest scorers in Ivy League history.
When he graduated, no professional teams offered Lin a contract, but he was invited to play in the NBA Summer League. He played well and ended up eagerly signing a contract with the Golden State Warriors.
At first,playing in professional games filled Lin with excitement. He treasured opportunities to meet players he had been watching on TV for years. But slowly, the excitement wore off and was replaced by anxiety. In a few very difficult months, he was cut by two teams before the New York Knicks picked him up.
But he had the courage and determination to stick to his dream, so he put himself into hard training to get ready for his opportunity to come. Then his moment arrived on February 4, 2012,on which his excellent performance made him famous overnight. After that, he led the Knicks to their fifth straight victory. Knicks fans developed the nickname for him "Linsanity" (林发疯). Time magazine released its 2012 list of the 100 "Most Influential People in the World", Jeremy Lin included.WhichofthefollowingisoflittlehelpinLin’ssuccess?
