Robots make me nervous-especially the ones which seem to think for themselves．I was embarrassed to admit this till I heard that Bill Gates，the founder of Microsoft，felt the same way．Gates said in an interview with the website Reddit：“I am in the camp that is concerned about super intelligence．First the machines will do a lot of jobs for us and not be super intelligent．That should be positive if we manage well．A few decades after that though the intelligence is strong enough to be a concern．”
Well，maybe I don’t have to worry about my laptop and kitchen appliances yet．After I use them I can always pull the plug．But in the future，machines might find a way to prevent us from switching them off．There’s a scary thought!
Professor Stephen Hawking warned a few months ago about the possibility that artificial intelligence could evolve and end up beyond human contro1．He suggested that machines could“spell the end of the human race”．
Maybe the problem with computers too clever for us is not that they are evil or rebellious．What could put us in danger is that they might be too efficient．That’s what philosopher Nick Bostrom from the Future of Humanity Institute at Oxford University believes．He says that machines are indifferent to humans and in pursuit of their own goals，the destruction of people might be just collateral(附带的)damage．A machine would not take pity on you．
I’m glad my machines at home are“dumb”．All my vacuum cleaner wants to take over is the carpet in my living room．Let’s hope they don’t create an appliance which wants to take over the world!
We can conclude from Gates’statements that ___________．
| A．he is embarrassed that he is afraid of robots |
| B．he doesn’t think machines are intelligent |
| C．machines should be fully employed |
| D．machines’super intelligence should be a concern |
The underlined word“spell”in Paragraph 3 is closest in meaning to _____________．
| A．record | B．cause | C．explain | D．develop |
Why are computers dangerous according to Nick Bostrom?
| A．They are too evil and rebellious． |
| B．They are indifferent to humans． |
| C．They show pity on humans． |
| D．They are too clever and efficient． |
What can be inferred about the author?
| A．He doesn’t agree with Bill Gates． |
| B．He is not content with the present kitchen appliances． |
| C．He is scared about the super intelligence of machines． |
| D．He expects that machines will take place of humans． |
Although being famous might sound like a dream come true, today’s star, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world’s attention. Paparazzi camp outside their homes, cameras ready. Tabloids (小报) publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature.
According to psychologist Christina Villarreal, celebrities—famous people—worry constantly about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. “Over time,” Villarreal says, “they feel separated and alone.”
The phenomenon of tracking celebrities has been around for ages. In the 4th century B.C., painters followed Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his sold-out readings attracted thousands of fans, leading him to complain about his lack of privacy. Tabloids of the 1920s and 1930s ran articles about film-stars in much the same way that modern tabloids and websites do.
Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modern cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their “story” alive forever.
If fame is so troublesome, why aren’t all celebrities running away from it? The answer is there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping to remote places away from big cities. They focus not on how famous they are but on what they love to do or whatever made them famous in the first place.
Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice often complain about how hard their lives are. They are tired of being famous already.It can be learned from the passage that stars today___________.
| A．are often misunderstood by the public |
| B．can no longer have their privacy protected |

| B．The problem faced by celebrities has a long history. |
| C．Well-known actors are usually targets of tabloids. |
| D．Works of popular writers often have a lot of readers. |

NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people’s memories are affected.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war.
They say that there are many people who suffer from terrible memories.
"Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
But those who are against the research say that maybe the pills can change people’s memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past.
"All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.The passage is mainly about.
| A．a new medical invention |
| B．a new research on the pill |
| C．a way of wiping out painful memories |
| D．an argument about the research on the pill |
The drug tested on people can.
| A．cause the brain to fix memories |
| B．stop people remembering bad experiences |
| C．prevent body producing certain chemicals |
| D．wipe out the emotional effects of memories |
We can infer from the passage that.
| A．people doubt the effects of the pills |
| B．the pill will certainly stop people's emotional memories |
| C．taking the pill will do harm to people's physical health |
| D．the pill has already been produced and used by the public in America |
Which of the following does Rebecca Dresser agree with in the last paragraph ?
| A．some memories can ruin people's lives. |
| B．people want to get rid of bad memories. |
| C．experiencing bad events makes us different from others. |
| D．the pill will reduce people's sufferings from bad memories. |
The national assistance system for poor college students is getting more effective as proved by fewer phone calls to the hotline of the National Center for Student Assistance Administration.
"Poor college students and their parents are getting more satisfied with the national assistance system," said Ma Wenhua, deputy director of the administration, on Saturday. Over the past three years, the hotline received 8,488 calls. Statistics show 62 percent of the calls were made to ask about the funding policy, while 38 percent (3,200 calls) complained local colleges had failed to abide by the rules to support the students.
Complaints were seen a year-on-year decrease from 2006 to 2008. Ma said some poor families might still overlook what they should do to get support for their child. To ensure education equality, the government has introduced a set of favorable policies to help poor students, such as scholarships, grants, student loans, tuition waivers(学费全免) and the work-study programs under which poor students are helped out in libraries, teachers' offices or service departments to earn money.
Statistics show the government spent 29.3 billion yuan last year to aid college students, up 7.6 percent from the previous year. Around 40 million persons of college students received the national aid.
The Ministry of Education of the government would ensure that no students drop out of colleges or universities because of poverty.

You’re finishing up your history homework when your cell phone rings. You’ve got 30 minutes to reach head-quarters, get your equipment packed and receive your task. There’s a lost hiker in the mountains near the edge of town. Your task: find the missing person; provide emergency medical treatment, if necessary; and be prepared to operate 48 hours on your own with only the supplies you carry.
Sounds like some kind of film’s plot? Not if you’re a member of the Arapahoe teen rescue patrol in the suburbs of Denver. About 25 teen guys and girls are active members of this search, rescue and emergency organization, and they know firsthand that you don’t have to be an adult to save lives.
These 9th-through-12th graders are the real deal when it comes to emergency services. In fact, they’re the only teen-commanded patrol in the nation. Sure they have adult advisers to turn to if necessary, but in the field it’s a teen patrol officer calling the shots — sometimes even giving direction to adults.
Members are trained in rock-high-angle，swift-water and avalanche rescue (雪崩施行营救), winter and alpine operation , wilderness life support and emergency care, among other skills. They also regularly ride along with the local fire and police departments, providing support such as security details and evidence searching.
When asked what qualities make a good patrol member, founder and president Stan Bush named good physical conditioning and an interest in helping people. “We put in lots and lots of hours helping people in trouble,” he says. “So if a person is not really interested in doing that kind of thing, he won’t last as a member.”In the first paragraph, the author describes ______.
