Since the 1970s, scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.
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.
BCI is a technology that can ________.

A．help to update computer systems

Cross-country skiing
There are 12 kilometers of cross country ski run in Narvik. You need to bring your own skis as there is no cross-country hire. However, equipment can be bought at local sports shops in and around Narvik.
Off-piste skiing（非场地滑雪）
In order to explore Narvik’s off-piste opportunities you need to know the dangers when choosing routes. It is suggested that you bring necessary equipment such as a shovel（雪铲）and a GPS locator. Ask Narvikfjellet for an experienced guide. With a guide you can explore Narvik’s special off-piste areas in a safe manner.
Sometimes it is nice to do something different and not everybody enjoys skiing. Then you can go horse-riding, or visit the local museums.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need.
We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place. The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place.
Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us.
We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
The author uses figures in Paragraph 2 to show _______.

A．the tendency of cutting household waste

B．the increase of packaging recycling

C．the rapid growth of super markets

D．the fact of packaging overuse

According to the text, recycling ______.

A．helps control the greenhouse effect

B．means burning packaging for energy

C．is the solution to gas shortage

D．leads to a waste of land

What can be inferred from Paragraph 4?

A．Unpackaged products are of bad quality.

B．Supermarkets care more about packaging.

C．It is improper to judge quality by packaging.

D．Other products are better packaged than food.

What can we learn from the last paragraph?

A．Fighting wastefulness is difficult.

B．Needless material is mostly recycled.

C．People like collecting recyclable waste.

D．The author is proud of their consumer culture.

We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.
What has the new study of more than 260,000 people found?

A．Sugary sodas aren’t good for the physical health of old people.

B．Americans have a special tooth for sweet foods.

C．Sweetened soft-drinks may increase the risk of depression.

D．Sweetened soft-drinks have important physical consequences.

What do we know about the process of the study?

A．About twenty-six thousand people participated in it.

B．The oldest participants were below 80 when the study was over.

C．Most of the participants had depression when the study was over.

D．The study lasted more than ten years from the beginning to the end.

It is implied in the passage that ______.

A．more research is needed to confirm the new findings

B．the new findings aren’t consistent with any previous findings

C．cutting one’s sodas intake will surely reduce one’s depression

D．the new findings won’t have an impact on people’s drinking habits

What should you drink in order to reduce the risk of depression?

A．Sodas.	B．Unsweetened coffee.
C．Sugary coffee.	D．Fruit punch.

Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her three-year-old son, Michael, prepare for a new sibling. They find out that the new baby is going to be a girl, and day after day, night after night, Michael sings to his sister in Mommy's tummy.
The pregnancy progresses normally for Karen. But complications arise during delivery. Finally, Michael's little sister is born. But she is in serious condition. With siren howling in the night, the ambulance rushes the infant to the intensive care unit at St. Mary's Hospital.
The little girl gets worse. The doctor tells the parents, "There is very little hope. Be prepared for the worst." Karen and her husband have fixed up a special room in their home for the new baby — now they plan a funeral.
Michael, keeps begging his parents to let him see his sister, "I want to sing to her," he says. But kids are never allowed in Intensive Care. However, Karen makes up her mind. She will take Michael whether they like it or not.“If he doesn't see his sister now, he may never see her alive.” She dresses him in an oversized scrub suit and marches him into ICU. The head nurse recognizes him as a child and bellows, "Get that kid out of here now! " The mother, the usually mild-mannered lady glares steel-eyed into the head nurse's face, her lips a firm line. "He is not leaving until he sings to his sister!" Karen tows Michael to his sister's bedside. He gazes at the tiny infant losing the battle to live. And he begins to sing.
"You are my sunshine, my only sunshine, you make me happy when skies are gray”
Instantly the baby girl responds. The pulse rate becomes calm and steady.
"You never know, dear, how much I love you. Please don't take my sunshine away "
The ragged, strained breathing becomes as smooth as a kitten's purr.
Keep on singing, Michael. Tears conquer the face of the bossy head nurse as well as Karen.
Funeral plans are scrapped. The next, day — the very next day — the little girl is well enough to go home!
