For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives.
“A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?” asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts.
These parts are not made of steel; they are the real things --- living cells, tissue, and even organs.
Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999，when a research group at North Carolina’s Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs 一 from kidneys to ears.
The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting
for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient’s body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient’s own cells and will not be rejected by the body’s immune system.
Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala’s medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney.
So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals’ chances of survival.In the latest field of regenerative medicine, what are replacement parts made of?

Dining in a completely dark room, unaware what’s on your plate while sitting next to a complete stranger may not sound like an ideal restaurant experience but it’s certainly an intriguing way to spend a rainy night in London.
Dans le Noir, close to London’s financial district, is a restaurant full of blind waiters and waitresses who become your eyes around the restaurant, whose original Paris branch opened in 2004.
In the bar with the light, you choose whether you want the fish, meat or vegetable, but the dishes themselves remain a secret, as do the ingredients of the “surprise” cocktails. Bags, coats and devices(设备)that light up, including watches and mobile phones, are kept in the bar. Placing your hand on the shoulder of your guide, you are led to a table in a black dining room that sets up to 60 people. And it is dark.
The waiters tell you when the food is being placed down in front of you, then the fun begins, trying to get food into your mouth, then identifying just what it is that’s on your plate, and finally whether you have missed any of it.
It’s also a great chance to break social convention and eat using your fingers. Those same fingers are also the only way you can tell how much wine you’re pouring into your glass.
The happy atmosphere in the dining room also made the night memorable. You can’t really avoid talking to the person next to you at the long tables and guessing what the dishes are certainly provides adequate fuel for the conversations.
All will be revealed at the end of the meal when you are led back out into the lit bar. Not only do you finally get to see what you’ve just been eating but also who you’ ve been talking to for the last 90 minutes.What does the underlined word “intriguing.” in the first paragraph mean?

Endless playing of songs like All I want for Christmas in shops during the festive season doesn’t just drive us mad —the songs also make us more careless with our money, research has warned.
While repeated performance of Jingle Bells may seem like an innocent attempt to raise customers’ spirits during the nightmare of Christmas shopping, the songs also have a more delicate impact.
“Background music, or “Muzak”,can be used by marketers to impose cultures ---such as the commercialization of Christmas--- onto consumers and influence their behaviour,” experts said.
Dr. Alan Bradshaw of Royal Holloway, University of London, said, “Festive jingles are force-fed to Christmas shoppers in a bid to change their mood, influence their sense of time and what sort of products they buy. In other words, this is an attempt to control your shopping habits in a way that you might hardly be aware of.”
“Often we are told that we have the freedom to choose where we want to shop, but during Christmas the use of music in this way is so common that our freedom to choose disappears.”
Dr. Bradshaw and Prof Morris Holbrook of Columbia University examined the phenomenon and found that retailers often “dumb down” the music played in shops to relax customers, meaning it is easier to control their behaviour.
It is thought that slowing down the rhythm of music in shops can trick customers into thinking less time has passed, and therefore spend more time examining the shelves, for example.
Some providers of background music have been known to promote their services by claiming they can boost profits by controlling the behaviour of customers.
“A common trick is to take a popular current song and record an instrumental version which can be slowed down or sped up at different time of the day to influence behaviour in different ways,” Dr. Bradshaw said.
Background music is often classed as “Muzak” in honor of the Seattle-based company which began producing its soft-sounding melodies in the 1930s.According to Dr. Bradshaw, in what ways does Christmas music influence customers?
①their mood②their income
③their sense of time④ the sort of products they buy
| A．①②③ | B．①③④ | C．②③④ | D．①②④ |
Shopkeepers slow down the rhythm of music in shops to ___________.
| A．let customers spend more time shopping |
| B．make customers and sales assistants relaxed |
| C．let customers enjoy the beautiful music |
| D．help customers find what they really want |
What kind of music is now often adapted to influence customers in shops?
| A．Classical music | B．Popular modern songs. |
| C．Folk songs. | D．Jazz music. |
What is the best title of the passage?
| A．Music makes happy Christmas |
| B．Christmas “Muzak” |
| C．How to make Christmas music? |
| D．Christmas music makes us spend more |
According to the US Geological Survey, about seven million earthquakes strike worldwide every year—but fortunately, only about 1500 of these are of a magnitude(震级) of 5 or greater on the Richter scale. Certain areas, such as California and Japan, are more prone to earthquakes than others. Although the chance of being caught in “The Big one” is remote, it’s wise to be prepared if you live in a region where earthquakes are common.
Educate your family about earthquakes before a big one strikes. For example, they need to know to take shelter in a doorway or under a strong object if indoors, and never to run outdoors if they are inside. If outside, they need to know to stay away from power lines and buildings where objects could fall.
Teach family members how to turn off gas or water lines or electrical power that may need to be shut off after a quake if severe damage occurs.
Develop a plan. Where will your family meet in the event of a disaster? What if some people are at work or school? How will you know if they are safe? Where will you all meet up?
Pack a preparedness kit(衣物装备) and keep it in a safe location. In a major earthquake, it’s possible that you won’t be able to get into your house. Keep supplies in your car trunk or an outside storage shed if possible. Pack whatever your family is likely to need, enough for three days to a week, including food, water, medication, first aid and personal hygiene supplies, flashlights, a portable radio, blankets, clothes and shoes, cash, or camp stove, candles, matches or lighters, and a whistle.
Consider earthquake insurance for your home if you live in an earthquake-prone area. Regular homeowner’s insurance doesn’t cover earthquake damage.The underlined words “prone to ” in paragraph 1 can be replaced by___________.
| A．likely to suffer | B．frequent to explore |
| C．regular to measure | D．impossible to experience |
According to the passage, if you are outside in an earthquake, you should_________.
| A．stay where you are | B．hide under a big tree |
| C．avoid power lines | D．sit on the ground |
We can learn from the passage that_________.
| A．about 1,500 earthquakes happen every year |
| B．people should store some clothes in their houses in advance |
| C．family members should meet in their home after an earthquake |
| D．people suffering earthquakes often should buy earthquake insurance |
What would be the best title for the passage?
| A．How to Keep Safe in an Earthquake |
| B．How to Prepare for an Earthquake |

Micro bloggers：have you ever compared the number of fans on your Sina Weibo or Tencent micro blog with those of your friends ?Don’t imagine you have more fans just because your number is bigger——some of them might be “zombie fans”，or fake(假的)followers．
That’s what Chen Chuanliang ，creator of Leijian Network，found when he bet against his friend several months ago．Chen，who used to do data mining for Microsoft Asia Research Institute，discovered that there were far more invalid(无效的)micro blog accounts than he had imagined．
Later Chen picked 1 0 users on Sina Weibo and analyzed their statistics．Kai-Fu Lee，the former CEO of Google China，who’s on Chen’s list of research，posted a message on his micro blog after he found out that he had more than 1 million fake fans(out of about 5 million)，joking“I have 1 million zombie fans ?If united，we can finally defeat those plants．”
According to a report by S Weekly in March，zombie fans on micro blogs are defined as invalid accounts signed up by network companies for the purpose of increasing the number of fans for certain users and getting them more attention．

The Financial Times reported in August，that Newt Gingrich，a Republican candidate in the US presidential election，bought about 80 percent of his 1．3 million Twitter followers and tried to use them as help in his campaign．
Now there are also business deals through which users can get hundreds of thousands of fans for their micro blog accounts，by paying a small amount of money．
“We have been working to find ways to block or delete those invalid accounts，”Mao Taotao，a spokesperson for Sina Weibo told S Weekly.
“But as the fake accounts grow so fast，they’re going to be here for a while．Which of the following might be the best title for the passage?

There’s a guy like me in every state and federal prison in America，I guess—I’m the guy who can get these for you：cigarettes，a bag of cigar，if you want that，a bottle of wine to celebrate your son or daughter’s high school graduation，or almost anything else．．．within reason，that is．It wasn’t always that way．
I came to Shawshank when I was just twenty，and I am one of the few people in the prison who is willing to admit what he did．I committed murder．I put a large insurance policy on my wife，who was three years older than 1 was，and then I fixed the brakes of the car her father had given us as a wedding present．It worked out exactly as I had planned，except I hadn’t planned on her stopping to pick up the neighbour woman and the woman’s son on the way down Castle Hill and into town．The brakes let go and the car crashed through the bushes，gathering speed．Bystanders said it must have been doing fifty or better when it hit the base of the Civil War statue in the town arid burst into flames．
I also hadn’t planned on getting caught，but caught 1 was．I got a pass into this place．My state has no death penalty(死刑)，but I was tried for all three deaths and given three life sentences，to run one after the other．That fixed up any chance of parole(假释)I might have，for a long，long time．The judge called what I had done‘an extremely evil crime’, and it was ,but it is also in the past now．
Have I transformed myself，you ask ?I don’t know what that word means，at least as far as prisons and corrections go．I think it’s a politician’s word．It may have some other meaning，and it may be that 1 will have a chance to find out，but that is the future．．．
I was young，good—looking，and from the poor side of town．I met a pretty，headstrong girl who lived in one of the fine old houses on Carbine Street．She got pregnant later．Her father was agreeable to the marriage if 1 would take a job in the company he owned and ‘work my way up’．I found out that what he really had in mind was keeping me in his house and under his thumb，like a disagreeable pet that has not quite been housebroken and which may bite．Enough hate eventually piled up to cause me to do what I did．
Given a second chance 1 would not do it again，but I'm not sure that means I am transformed．What do we know about the man from the passage?
