The ISS project is a partnership of five - the US, Russia, Europe, Japan and Canada.
At the moment, no program for its use nor any money has been put in place to support the platform beyond 2015.  
One of the biggest issues stopping an agreement on station-life extension(延长期) is the human spaceflight examination ordered by US President Barack Obama.
The Americans are developing a new vision for space exploration, and the rockets and spacecraft they will need to start it. The future of US joining in the ISS is closely tied to the result of the examination.
Mr Dordain, the European Space Agency's (Esa) Director General, said no one partner in the ISS project could alone call an end to the platform. A meeting would be held in Japan later in the year where he hoped the partners could get something clearly going forward. He said it was also necessary the benefits(成效) were increased and the costs were reduced. Increasing the benefits could include finding new uses for the station.
Esa has called for ideas on how to use the ISS as a platform for Earth observation(观测站). Mr Dordain said the agency had received about 20 very good proposals.
On the issue of reducing costs, there were many ideas on the table, he explained.
He also questioned whether it was necessary for the station to have six astronauts at all times. If there were periods when little maintenance(维修) was required or the experiment load was light, could the ISS run on a smaller group of people, he suggested.
Construction of the space station should finish this year. Next month, two components built in Europe - a connecting node and a robotic control room - will be flown to the platform by the US shuttle Endeavour.
Tranquility and the Cupola, as they are known, will complete the non-Russian side of the ISS.
Why will America joining in the ISS be tied to the result of the examination?

A.Because America is the greatest power among them
B.Because America provides most of the money
C.Because they need America’s rockets and spacecraft
D.Because Obama ordered the human spaceflight examination

According to Mr Dordain, how should they do to reduce costs?

A.To find new uses for the station
B.To make little maintenance
C.To reduce the experiment load
D.To have fewer astronauts sometimes

Where do you think you can read this passage?

Several recent studies have found that being randomly (随机地) assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood (可能性)of conflict.
Recent reports found that lodging with a student of a different race may decrease prejudice and cause students to engage in more ethnically diverse friendships.
An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.
In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove."
Researchers also observed problems resulting from pairing interracial students in residences.
According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out.
An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester.
Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said.
At Penn, students are not asked to indicate race when applying for housing.
"One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration."
"I've experienced roommate conflicts between interracial students that have both broken down stereotypes(老一套,模式) and reinforced stereotypes," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合)," there were also "jarring(不和谐的)cultural confrontations(对抗)."
The RA said that these conflicts have also occurred among roommates of the same race.
Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained.
What can we learn from some recent studies?

A.Conflicts between students of different races are unavoidable.
B.Students of different races are prejudiced against each other.
C.Interracial lodging does more harm than good.
D.Interracial lodging may have diverse outcomes.

What does Sam Boakye's remark mean?

A.White students tend to look down upon their black peers.
B.Black students can compete with their white peers academically.
C.Black students feel somewhat embarrassed among white peers during the freshman year.
D.Being surrounded by white peers motivates a black student to work harder to succeed.

What does the Indiana University study show?

A.Interracial roommates are more likely to fall out.
B.Few white students like sharing a room with a black peer.
C.Roommates of different races just don't get along.
D.Assigning students' lodging randomly is not a good policy.

What does Alec Webley consider to be the "definition of integration"?

A.Students of different races are required to share a room.
B.Interracial lodging is arranged by the school for freshmen.
C.Lodging is assigned to students of different races without exception.
D.The school randomly assigns roommates without regard to race.

What does Grace Kao say about interracial lodging?

A.It is unscientific to make generalizations about it without further study.
B.Schools should be cautious when making decisions about student lodging.
C.Students' racial background should be considered before lodging is assigned.
D.Experienced resident advisors should be assigned to handle the problems.

“Long time no see” is a very interesting sentence. When I first read this sentence from an American friend’s email, I laughed. I thought it was a perfect example of Chinglish.
Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too thrilled to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.
Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan’s movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.
Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.
You can have some other examples besides adoptions from Chinese, such as pizza from Italian, sushi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.
The writer himself felt surprised at ______.

A.the Chinglish expression “Long time no see”
B.“Long time no see” used as standard American English
C.so many literal translation of the expressions used in America
D.finding out Americans use the expression every day

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

A jobless man applied for the position of “office boy” at Microsoft. The HR manager interviewed him and then watched him cleaning the floor as a test.
“You are employed,” he said. “Give me your e-mail address and I’ll send you the application to fill in, as well as date when you may start. ”
The man replied, “But I don’t have a computer, neither an e-mail. ”
“I’m sorry,” said the HR manager. “If you don’t have an e-mail, that means you do not exist. And who doesn’t exist cannot have the job. ”

Almost every child is scared of something, from monsters in the cupboard to dogs in the park. But the fact that such fears are common and normal doesn’t mean they can be taken lightly. Kids experience fears and phobias(恐惧症) much more strongly than adults. And the influence of the fear can be physical as well as psychological (心理的). It can build up so they almost seem scared of everything--a kind of childhood anxiety. Dr. Creswell says: “Your child may always seem to expect the worst to happen and lack confidence in his or her ability to deal with any challenge.” So don’t make the same old mistake of treating them as if they’re silly for being a“scaredy cat”. Handling the fears is essential.
Children can be born nervous and, if you have such a baby, you’ll tend to prevent them from getting worried. So if they fear dogs, you’ll keep them away from dogs, but in fact that can just confirm to the child that dogs are scary. What is worse, keeping your child away from what they fear can turn that feeling into a phobia. Instead, you should encourage them to get in touch with the thing they fear, in a safe and supportive environment. Dr. Andy Field, a researcher of childhood fears, says: “You shouldn’t force, for example, a dog anxious child to go up to a dog. But you can approach it yourself, show them there is nothing to be afraid of, stroke( 抚摸) it, and talk about the dog being friendly. Once your child dares to stroke a dog-one that’s good with children, of course---then you should encourage them to carry on until they feel calmer, and reward them for‘being brave’.”
Children’s fears are usually taken lightly because.

A.they will not develop into phobias
B.their influence is psychological
C.they exist widely in the world
D.they will disappear gradually

If we fail to help children to overcome fears, they will.

A.make the same old mistake
B.overcome them by themselves
C.experience the worst of things
D.grow up lacking self-confidence

According to Dr. Andy Field, if a child is afraid of a cat, parents should.

A.tell the child not to be afraid of it
B.show the child how to approach it
C.keep the child away from it
D.ask the child to stroke it
