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 have NASA money because it won’t have to ship up as much water to the station by space shuttles or cargo 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 shuttles 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 congratulated engineers in two NASA centres 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 vapor(水蒸气) is collected. The rest of the urine is thrown away. Then the water vapor 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 six gallons from urine in about six 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．with it NASA won’t need to ship any water up the space station |
| C．it can help meet the need for more water after the crew is expanded |
| D．it protects the environment in space by reducing the amount of waste |
What’s the RIGHT time order of the following events?
a. The samples of the recycled water were tested on earth.
b. Astronauts celebrated the space first of making water from urine
c. The recycling system was brought up to the space station.
d. The technology for the system was used to quickly purify water.

It’s such a happy-looking library, painted yellow, decorated with palm-tree stickers and sheltered from the Florida sun by its own roof. About the size of a microwave oven, it’s pedestrian-friendly, too, waiting for book lovers next to a sidewalk in Palm Beach country Estates, along the northern boundary of Palm Beach Gardens.
It’s a library built with love.
A year ago, shortly after Janey Henriksen saw a Brian Williams report about the Little Free Library organization, a Wisconsin-based nonprofit that aims to promote literacy and build a sense of community in a neighborhood by making books freely available, she announced to her family of four, “That’s what we’re going to do for our spring break!”
Son Austin, now a 10th-grader, didn’t see the point of building a library that resembles a mailbox. But Janey insisted, and husband Peter unwillingly got to work. The 51-year-old owner of a ship supply company modified a small wooden house that he’d built years earlier for daughter Abbie’s toy horses, and made a door of glass.
After adding the library’s final touches, the family hung a signboard on the front, instructing users to “take a book, return a book,” and making the Henriksen library, now one of several hundred like it nationwide and among more than 2,500 in the world, the only Little Free Library in Palm Beach County.
They stocked it with 20 or so books they’d already read, a mix of science fiction, reference titles, novels and kids’ favorites. “I told them, keep in mind that you might not see it again,” said Janey, a stay-at-home mom.
Since then, the collection keeps replenishing itself, thanks to ongoing donations from borrowers. The library now gets an average of five visits a day.
The project’s best payoff, says Peter, are the thank-you notes left behind. “We had no idea in the beginning that it would be so popular.” In what way is the library “pedestrian-friendly”?
| A．It owns a yellow roof. |
| B．It stands near a sidewalk. |
| C．It protects book lovers from the sun. |
| D．It uses palm-tree stickers as decorations. |
The library was built __________.
| A．by a ship supply company |
| B．on the basis of toy horses |
| C．like a mailbox |
| D．with glass |
What can we infer about the signboard?
| A．It was made by a user of the library. |
| B．It marked a final touch to the library. |
| C．It aimed at making the library last long. |
| D．It indicated the library was a family property. |
The passage tells us that the users __________.
| A．donate books to the library |
| B．get paid to collect books for the library |
| C．receive thank-you notes for using the library |
| D．visit the library over 5 times on average daily |

We are fortunate to be living in a time when all people have the ability to access any knowledge they desire. This digital society that we live in affords us opportunities that our ancestor only dreamed of having. We should not take this privilege for granted.
In the not so distant past of the 1950s, people who wanted to research an idea, a product, or anything else, had to go to a library where they could look up information in books. Not all people had the same access to the books, and the information they contained. In America, if your skin was black, you could not use the same library that a person with white skin used. If a black skinned person was allowed access to a library, it most likely was stocked with outdated books that white skinned people had discarded.
In the digital society we live in today, the color of your skin does not determine the access you have to information. Technology has brought to us the powerful tools like the Internet where we can find information on almost every subject.
Access to the Internet has allowed us to research the things we are planning to purchase. We are capable of comparing prices on things like insurance, appliances, entertainment, clothing, and all other things. We also now have the ability to purchase items online without ever leaving our homes. We have been freed from the restrictions of store hours, and regional sales. A person in America can purchase a product from a person in Germany, without leaving home.
Because of the digital society we live in our children can learn about anything they are interested in. When they ask you what the dinosaurs ate, you can look it up, and tell them the answer. Because of this people will be smarter in the future, and technology will only improve.By “We should not take this privilege for granted”, the writer means that ______.
| A．we have special right to do anything |
| B．it is wrong to make use of the privilege |
| C．knowledge is important in the digital society |
| D．we should seize the chances the modern society offers |

| A．people will be much clever than ever |
| B．what the dinosaurs ate seems strange to us |
| C．finding out what the dinosaurs looked like is easy |

When I first told people I was going to work in Cameroon, the most common reaction was: “Why?” The second was: “It’s in Africa; you’ll die!” The third: “Where is that?”
So let me give some answers. I was offered a job that looked interesting in a part of the world I’d never been to before. I’d also long had an interest in Africa, so I decided it was time to find out the reality.
A small amount of research showed that in more than 40 years since gaining independence, Cameroon has been a peaceful country with no wars. Not only are there no wars, but Cameroon is a food exporter to the region.
Now, after three years, I can say that these have been the healthiest years of my life! No malaria or any of the other frightening diseases you read about when Africa is mentioned. The worst thing that ever happened to me was a bout of food poisoning — once.
So what is it like to teach here? Well surprisingly not so different from teaching anywhere else.
Most students come to us with a bit of English in their heads. Cameroon is a bilingual country with French and English as official languages, while there are also close to 200 local ethnic languages in a country of 16 million people. French is the dominant language, spoken by about 80% of the population.
The local school system is very traditional and somewhat strict. Perhaps not surprisingly when there can be up to 150 students in the classroom (of which maybe 30 have the books, and there are probably seats for 70).
Like anywhere else, students appreciate it if you know a bit about their country, and not just Roger Milla (the top scorer of the 1990 World Cup, in case you’re wondering). It helps if you know the names of the ten provinces, know who the first president was, or can say a word in a local language.
So in conclusion: Cameroon isn’t just football. Not is it war, poverty and disease. It’s just life and people, like anywhere else. On hearing the writer’s decision, most people _____.
| A．didn’t understand him | B．considered it as a joke |
| C．admired him | D．laughed at him |
According to the passage, Cameroon is _____.
| A．a country full of diseases | B．peaceful after liberation |
| C．a poor country, especially lack of food | D．quite different from others in education |
What can we infer from the passage?
| A．Food export may lead to many frightening diseases. |
| B．Most students in Cameroon do not need books |
| C．Cameroon is not as bad as people commonly believed |
| D．There must be a lot of people suffering from food poisoning. |
What does the underlined word in the sixth paragraph mean?
| A．leading | B．easy | C．only | D．wonderful |
My parents always raised me to have strong values and hold firm to my confidence in life, and this was never more proved than when a situation arose when it would be easy for most people to ignore it.
A gentleman at my father’s work smelled awful and neglected his behavior, and as the months went by, he showed signs of confusion. After being told to pick up papers at another building, he would be found sitting at his desk staring at his shoes; after being reminded (to which he would completely believe he hadn’t been told the first time), he would be found once again sitting at his desk in the same position. This happened to worsening degrees over a few months and his coworkers either ignored it or were ignorant to this due to a lack of social association with the man.
My father began to mentally record all of this and finally sat down with him one day when he was found two hours after work was out, sitting in his car, looking like he didn’t know where to go. Apparently the gentleman was in the beginning/middle stages of Alzheimer’s and there was someone who used his forgetfulness as a reason to ask him for money every few days. My father took this man to a hospital (for the first time in years) to be properly treated, and then got a caretaker to watch over his condition. He then went to the man’s house and helped him sort out all of his financial matters and get his retirement set up; they went to the bank and had a government worker ensure that his bills would be paid for and his children would no longer get to treat him like a personal ATM.
That my father took his much personal time to help another man that so many had forgotten or would choose to neglect, or even make fun of, truly shows his character.The author presents this passage by ______.
| A．telling an instructive story | B．describing his father |
| C．reasoning with some facts | D．giving causes and effects |
What can we infer from the passage?
| A．The gentleman was ignored by his co-workers. |
| B．The gentleman was so serious that no one liked him. |
| C．The gentleman was good at communication with his co-workers. |
| D．The gentleman was in great need of help because of his illness. |
In the eyes of the author, his father is ______.

| A．A friend in need is a friend indeed. |
| B．A friend to all is a friend to none. |
