In the past, friendships were greatly limited by time, space and attention； increasing home and workplace mobility has made it even harder to keep social relations over time. Through a combination of user controls, new technologies and changing standards of social behavior, Facebook is freeing us from these limitations, making friendships more accessible, pleasant and diverse than ever before.

First, Facebook allows you to find and rediscover friends and then reminds you of these connections, so that you are less likely to fall out of touch with the long-lost school friend, or the family member in a different country. 'Second, Facebook creates an environment that allows you to interact easily with others ： you can share your photos，videos，links and thoughts with your friends， and respond to what they share in turn. Third, Facebook’s unique technical system helps you to discover your friends，most valuable stories. These technologies allow people to keep and enrich friendships that they might otherwise have been unable to keep.

The effect of this is very great. A recent study by Keith Hampton for the Pew Internet and American Life Project discovered that users of social networking websites have larger, more diverse social circles, online and offline. This outcome comes at no cost to one’s closest relationships, which are kept in person and over the phone. Instead, the hour that the average user spends each day socializing on Facebook comes at the expense of less social activities, such as the three or so hours a day the average person spends watching television.

Time may limit our ability to keep social ties, but our desire for social communication is limitless. Just as boats have allowed us to cross oceans and vehicles have allowed us to move mountains, Facebook is a tool that allows us to stay more deeply connected with a larger and more diverse set of friends.

Imagine that 7 out of 10 working Americans got fired tomorrow. What would they all do? It’s hard to believe it would happen. But that is what the industrial revolution did to the labor force of the early 19th century.

Two hundred years ago, 70 percent of American workers lived on the farm. Today automation(自動(dòng)化) has eliminated all but one percent of their jobs, replacing them with machines. But these workers did not sit, doing nothing. Instead, automation created hundreds of millions of jobs in completely new fields. Those who once farmed were then working in factories that produced farm equipment, cars, and other industrial products.

It may be hard to believe, but before the end of this century, 70 percent of today’s jobs will likely be replaced by automation. Yes, dear reader, even you will have your job taken away by machines. In other words, robot replacement is just a matter of time, First, speedy robots being able to lift 150 pounds all day long will carry boxes, sort them, and load them onto trucks. Fruit and vegetable picking will continue to be robotized until no humans pick outside of specialty farms. Next, The work of cleaning in offices and schools will be taken over by late-night robots. The trucks will be driven by robots.

We need to let robots take over. They will do jobs we have been doing, and do them much better than we can. They will do jobs we can’t do at all. They will do jobs we never imagined even needed to be done, and they will help us discover new jobs for ourselves and new tasks that expand who we are. They will let us focus on becoming more human than we were.

1.What happened in the early 19th century?

A. Some working Americans in factories got fired.

B. Jobless workers had no choice but to sit there doing nothing at all.

C. Many American workers had to leave factories to work on the farm.

D. The industrial revolution caused many Americans to lose their jobs.

2.How does the author support the underlined statement in Paragraph 3?

A. By giving advice.

B. By giving examples.

C. By following the order of time.

D. By explaining cause and effect.

3.How does the author feel about robots taking over our jobs?

A. Afraid. B. Happy. C. Puzzled. D. Angry.

4.What does the author want to tell us in the text ?

A. Why robots should take over our jobs.

B. 70% of working Americans will be jobless.

C. The industrial revolution led to the automation.

D. Robots will do more things for us to live better.

Darek Fidyka, a 38-year-old Bulgarian, had been paralysed (癱瘓的) from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted (移植) them into his back and re-grew his spinal cord (脊髓). Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.

The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal (鼻腔的) nerves, the only part of the nervous system that constantly re-grows. “The idea was to take something from an area where the nervous system can repair itself, and does so throughout life, and put it into an area that doesn’t repair itself,” Professor Raisman said.

Polish doctors injected the nasal cells into Mr Fidyka’s spinal cord above and below the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.

Professor Raisman achieved this with rats in the late 1990s, but this is his greatest success. “I think the moment of discovery for me was Christmas in 1997 when I first saw a rat that couldn’t control its hand put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true.”

Doctors chose the easiest case for their first attempt — it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.

David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.

“What you’ve got to understand is that for three million paralysed people in the world today, the world looks a totally brighter place than it did yesterday,” he said.

1.Why did Professor Geoff Raisman choose cells from the nose?

A. The nervous system in the nose can repair itself.

B. Cells in the nose can be easily transplanted.

C. Cells in the nose re-produce rapidly.

D. He just wanted to give it a try.

2.What made Professor Geoff Raisman believe the nervous system can be repaired?

A. His study on animals.

B. His operation on a paralysed patient.

C. His sudden thoughts about Christmas.

D. His unusual experience with a sick rat.

3.David Nicholls’ words suggest that _____.

A. the world is becoming better and brighter

B. paralysed people have the hope of recovery

C. the report of the breakthrough will be published soon

D. researchers across the globe will carry out the operation

I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled everything. I always looked for everything.
