1 . The word "orange" describes both a color and a fruit. Which one came first might be surprising. "Orange" when used as the name of the fruit came before "orange" as a word to describe color. While the shade itself existed before the fruit, there was not a name in the English language for the color. Before the introduction of the fruit to English-speaking countries, the color was usually described as a shade of red or yellow.
In the early 16th century, Portuguese traders brought oranges from India to Europe. The Europeans had not seen the bright colored fruit before and didn't have a name for it. The fruits were named "narancia" by Italians and "narange" by the French and were sometimes referred to as "golden apples" by English speakers.
"Orange" was first used in a phrase to describe shades of colors, including in a third-century Greek text translated into English, in 1576. It describes Alexander the Great's servants as dressed in "orange colour velvet （天鹅绒）In 1578, a Latin-American dictionary defined "melites" as "a precious stone of orange color”. While orange represents the color of the objects, it needed the word "color" to follow it in order for the meaning to be clear. In the mid-1590s, Shakespeare described a beard as "orange tawny", one of the first instances of "orange" without the word "color" as part of the expression. Tawny is a brown color often used on its own. Orange was not yet a color, just a shade of brown.
In 1616, in an account describing varieties of tulips （郁金香）that can be grown, orange was used as a stand-alone color. When Isaac Newton performed his experiments on the color spectrum （色谱），he listed it as one of the seven basic colors. After almost half a century, orange was recognized as a color on its own.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.
1. BCI is a technology that can ________.
| A．help to update computer systems |
| B．link the human brain with computers |
| C．help the disabled to recover |
| D．control a person's thoughts |
| A．By controlling his muscles. |
| B．By talking to the machine. |
| C．By moving his hand. |
| D．By using his mind. |
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |
| A．make profits from them |
| B．prove the technology useful to them |
| C．make them live longer |
| D．learn about their physical condition |

3 . One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes.
“Nothing fits,” said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. “Everyone says this. They order clothes and they don’t fit. People get very unhappy.”
Wong and her design partner, Xuaner “Cecilia” Zhang, are Team White Mirror, creators of what they call a “virtual (虚拟) fitting room”. Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time.
Both women are from China, Wong from Hong Kong and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. “They say, ‘The color is wrong’ or ‘I got the right size but it still does not fit.’ We want to make it like you’re in the store trying on the clothes,” Zhang said.
Using a Kinect developed by Microsoft for use with its Xbox 360 video game player,
Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong’s dimensions (尺寸), and even her skin and hair color. “We put the clothes on the shopper’s 3-D body models and show how they look when they are dressed,” Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts.
Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, “I think their wives will care about this, so it will also be important to men.”

Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain' s temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

So how does it work? First you have to sign up to the scheme to be sent a key. The key will unlock one of the bikes, which are kept at docking stations in and around central London. You have to pay an access fee for the key and then you pay as you go, for the length of time you use the bike.
Transport for London, which runs the scheme, is hoping to have 6,000 bikes and 400 docking stations in place by the end of the year. The new hire system is hoping to ease congestion (拥挤) in London and is expected to create up to 40 ,000 extra cycle trips a day into the city centre. London Mayor Boris Johnston launched the scheme and said London had been 6ifilled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses".
However, there have been a few problems since the scheme was launched last Friday. On the first day some people found they couldn't dock their bike properly and their usage of the bike had not registered. Transport for London did admit they had been expecting a few "teething problems" and have said they wouldn't charge for the first day as a "gesture of goodwill". Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.
Despite the comments, the green-thinking London Mayor still seems very positive about things, saying, "My campaign for the capital to become the greatest big cycling city in the world has taken a big pedal-powered push forwards. "
