You may have never heard of Lanthanum, Cerium or Neodymium, but these elements (元素) and others known as “rare earth” play a major role in modern technology. They can actually be found in many places on the earth, but not in quantities that can be mined. Only a few countries — China, America, India, Australia, Brazil and Malaysia have any that can be mined enough to be traded.
Even though some of these elements such as Cerium are as abundant as Copper, they are not found in concentrated amounts on the earth’s surface. They are often mixed together with other metals, which makes extraction (提取) of these elements an expensive and an environmentally messy process. It was due to this reason that the term “rare earth” was invented.
Rare earth metals are used widely in our life. Rechargeable car batteries, computers, iPhones, DVD players, computer monitors, televisions, lighting, lasers, glass polishing, and superconductors all use quantities of rare earth metals. Also, with the advancement in “green” technology like solar panels, these shiny materials are becoming more important than ever. An average electric car uses 10 pounds of Lanthanum for its rechargeable battery!
America has large deposits (存储量) of rare earths and has one of the first mines. It was opened in Southern California in 1940. The element “Europium” was the first metal to be separated in quantity for use in color televisions. However, in the 1980’s and 1990’s, as China started producing these elements in Inner Mongolia, the mines in America and elsewhere could not keep pace. The mine in Mountain Pass, California also failed environmental regulations and shut down in 2002.
Now, recognizing the importance of having more than one supplier of this important resource, other rare earth owning countries like India and Australia are either dusting off their rare earth mines or speeding up their production. It is believed that the debate over rare earths will become louder in the coming months and years.What can we learn about rare earths?

Miss Gorgers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That’s very good.” Miss Gorgers answered, but then one of the girls raised her hand, and Miss Gorgers said, “Yes? Kate.”
“I disagree. Your brother would hear you earlier because when it’s 11 o’clock he
re and it’s only 8 o’clock in Los Angeles.” Kate said.

It had been some time since Jack had seen the old man. College, career, and life itself got in the way. In fact, Jack moved clear across the country in pursuit of his dreams. There, in the rush of his busy life, Jack had little time to think about the past and often no time to spend with his wife and son. He was working on his future, and nothing could stop him.
Over the phone, his mother told him, “Mr. Belser died last night. The funeral is Wednesday.” Memories flashed through his mind like an old newsreel（纪录片） as he sat quietly remembering his childhood days.
“Jack, did you hear me?”
“Oh, sorry, Mom. Yes, I heard you. It’s been so long since I thought of him. I’m sorry, but I honestly thought he died years ago,” Jack said.
Well, he didn’t forget you. Every time I saw him he’d ask how you were doing. He’d reminisce (回忆) about the many days you spent over ‘his side of the fence’ as he put it,” Mom told him.
“I loved that old house he lived in,” Jack said.
“You know, Jack, after your father died, Mr. Belser stepped in to make sure you had a man’s influence in your life,” she said.
“He’s the one who taught me carpentry. I wouldn’t be in this business if it weren’t for him. He spent a lot of time teaching me things he thought were important… Mom, I’ll be there for the funeral,” Jack said.
Busy as he was, he kept his word. Jack caught the next flight to his hometown. Mr. Belser’s funeral was small and uneventful. He had no children of his own, and most of his relatives had passed away.
The night before they had to return home, Jack and his Mom stopped by to see the old house next door one more time, which was exactly as he remembered. Every step held memories. Every picture, every piece of furniture… Jack stopped suddenly.
“What’s wrong, Jack?” his Mom asked.
“The box is gone,” he said.
“What box?” Mom asked.
“There was a small gold box that he kept locked on top of his desk. I must have asked him a thousand times what was inside. All he’d ever tell me was ‘the thing I value most’,” Jack said.
It was gone. Everything about the house was exactly how Jack remembered it, except for the box. He figured someone from the Belser family had taken it.
“Now, I’ll never know what was so valuable to him,” Jack said sadly.
Returning to his office the next day, he found a package on his desk. The return address caught his attention.
“Mr. Harold Belser” it read.
Jack tore open the package. There inside was the gold box and an envelope. Jack’s hands shook as he read the note inside.
“Upon my death, please forward this box and its contents to Jack Bennett. It’s the thing I valued most in my life.” A small key was taped to the letter. His heart racing, and tears filling his eyes, Jack carefully unlocked the box. There inside he found a beautiful gold pocket watch. Running his fingers slowly over the fine cover, he opened it.
Inside he found these words carved: “Jack, Thanks for your time! Harold Belser.”
“Oh, My God! This is the thing he valued most…”
Jack held the watch for a few minutes, then called his assistant and cleared his appointments for the next two days. “Why?” his assistant asked.
“I need some time to spend with my son,” he said.Why did Jack think Mr. Belser died years ago?
| A．College and career prevented him from remembering Mr. Bleser. |

| C．He had missed his son and his family for days. |

Drunken driving –sometimes called America’s socially accepted form of murder—has become a national epidemic (流行病). Every hour of every day about three Americans on average are killed by drunken drivers，adding up to an incredible 250,000 over the past ten years. A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts，but the drunken killing has recently caused so many well-publicized tragedies，especially concerning young children，that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21，reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18，the number of people killed by 18-20 years old drivers more than doubled，so the state recently upped it back to 21.
Reformers，however，fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop ‘responsible attitudes’ about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests in many areas already，to a marked drop in accidents，some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who was ‘obviously drunk’ and later drove off the road，killing a 9-year-old boy.
As the accidents continue to occur daily in every state，some Americans are even beginning to speak well of the 13 years national prohibition of alcohol that began in 1919，which President Hoover called the ‘noble experiment’. They forgot that legal prohibition didn’t stop drinking，but encouraged political corruption and organized crime. As with the booming drug trade generally，there is no easy solution. Statistics issued in New Jersey suggested that ____________.
| A．many drivers were not of legal age. | B．young drivers were often bad drivers. |
| C．the level of drinking increased in the 1960s. | D．the legal drinking age should be raised. |
The underlined word ‘lenient’ in the first paragraph means ‘_________’.
| A．serious | B．cruel | C．merciful | D．determined |
In America, public opinion about drunken driving has changed because __________.
| A． judges are no longer tolerant |
| B． new laws are introduced in some states |
| C． the increasing number of traffic accidents has got the attention of the public |
| D． drivers do not appreciate their manly image any more |
Which of the following best shows the writer’s opinion of drunken driving?
| A．It may lead to organized crime. | B．It is difficult to solve this problem. |
| C．The new laws can stop heavy drinking. | D．There should be no bars to serve drinks. |
When Gretchen Baxter gets home from work as a New York City book editor, she checks her Blackberry (黑莓手机) at the door. ‘I think we are attached to these devices in a way that is not always positive,’ says Baxter，who’d rather focus at home on her husband and 12-year-old daughter. ‘It’s there and it beckons (召唤). That’s human nature (but)…we kind of get crazy sometimes and we don’t know where it should stop.’
Americans are connected at unprecedented (前所未有的) levels一93% now use cell phones or wireless devices；one third of those are ‘smart phones’ that allow users to browse the Web and check e-mail，among other things. The benefits are obvious: checking messages on the road，staying in touch with friends and family，efficiently using time once spent waiting around. The downside：often，we’re effectively disconnecting from those in the same room.
That's why，despite all the technology that makes communicating easier than ever，2010 was the Year We Stopped Talking to One Another. From texting at dinner to posting on Facebook from work or checking e-mail while on a date，the connectivity revolution is creating a lot of divided attention，not to mention social anxiety. Many analysts say it's time to step back and reassess.
‘What we’re going to see in the future is new opportunities for people to be plugged in and connected like never before,’ says Scott Campbell. ‘It can be a good thing，but I also see new ways the traditional social fabric (社会结构) is getting somewhat torn apart.’
Our days are filled with beeps and pings·----many of which pull us away from tasks at hand or face-to-face conversations. We may feel that the distractions are too much，but we can’t seem to stop posting，texting or surfing.
‘We're going through a period of adjustment and rebalancing,’ says Sherry Turkle and she wants to remind people that technology can be turned off.
‘Our human purposes are to really have connections with people,’ she says. ‘We have to reclaim it. It’s not going to take place by itself.’What can be the best title for the passage?
| A．2010: The year technology developed quickly. |
| B．2010: The year technology sped up our life pace. |
| C．2010: The year technology replaced talking. |
| D．2010: The year technology made communicating easier. |
According to Paragraph l，Gretchen Baxter thinks_________.
| A．the new technology always influences people’s life in a positive way |
| B．the new technology is so tempting that she could even put her daughter and husband behind |
| C．it is encouraging to see progress on the new technology every year |
| D．people are too dependent on the new technology to let go |
Which of the following is TRUE according to the passage?
| A．The wide use of mobile devices has nothing to do with the ‘traditional social fabric’. |
| B．Mobile devices play a less important part in American life. |
| C．Mobile devices create a lot of divided attention and social anxiety. |
| D．Many analysts speak highly of the wide popularity of mobile devices. |
What can be inferred from the last paragraph?
| A．Something must be done to get connection with people in reality again· |
| B．Using mobile services can help people get connection with each other. |
| C．Mobile services have a strong impact on people’s life. |
