Recently, scientists have developed a wireless brainmachine interface that help restore communication to people who can no longer speak by reading brainwaves using electrodes(电极) stuck on their heads. Unfortunately, these have proved very slow, at roughly one word typed per minute, making normal conversations and social interactions virtually impossible.
Scientist Frank Guenther and his colleagues reveal a brainmachine interface that uses electrodes implanted directly into the brain for research into real time speech.
"It should soon be possible for extremely paralysed individuals who are incapable of speaking to produce speech through a laptop computer, " said Guenther.
The scientists worked with a 26-year- old male volunteer who experience near-total paralysis due to a stroke he suffered when he was 16. They implanted an electrode that had two wires into a part of the brain that help plan and execute movements related to speech. The electrode recorded brain signals when the volunteer attempted to talk and the wires spread them across the scalp(头皮)to help drive a speech synthesizer (合成器). The delay between brain activity and sound output was just 50 milliseconds on average, roughly the same with regular speech.
"He was quite excited, particularly on the first few days we used the system, as he got used to its properties, " Guenther recalled." I am sure the work proceeds slowly from his perspective, as it does from ours. Nonetheless, he was very excited about getting real-time audio feedback of his intended speech and happy to work very hard with us throughout the experiments."
"The current system uses data from just two wires. Within a year it will be possible to implant a system with 16 times as many." Guenther said." This will allow us to tap into neurons(神经元)，which in the end means better control over a synthesizer and thus better speech."In the study of Guenther, electrodes are _______.
| A．fixed on the heads | B．put into the heads |
| C．tied to the heads | D．separated from the heads |
The underlined word "them" in Paragraph 4 refers to _______.
| A．movements | B．wires | C．brain signals | D．Scientists |

A Bite of China, featuring delicious Chinese food, has attracted countless viewers, and moved many to tears.
A Bite of China is a serious documentary providing a unique view of Chinese as well as the relations between people and food and between people and society from the view of food. The touching documentary reminds some people of their mother, and makes some realize that every grain comes from hard and laborious work. Some people see patriotism(爱国精神) in the documentary, and some consider it a great cultural export.
How did this documentary achieve a great influence beyond its subject matter in such a short time?
“It is not empty propaganda(宣传) about China’s splendid food culture. Instead, it shows the techniques used in making food and their production process as well as the lives of ordinary people, thus striking a chord(共鸣) with the audience,” an Internet user said. The success of the documentary should be owed to sincerity and reality. Nowadays, many works of art that have high investment, high technology, and magnificent scenes lack nothing but sincerity and reality.
A Bite of China shows that a commercial documentary promoting patriotism can be full of touching details, that the emotions of ordinary Chinese people should be exhibited even in publicizing(宣传) China overseas, and that even a completely commercial program can achieve both artistic and commercial success.
“We made this documentary with our respect and love for food,” said director Chen Xiaoqing. Being sincere is the most important thing for artists because they cannot move others unless they themselves are first moved, and cannot convince others unless they themselves are first convinced. Sincerity is the “secret” for making this documentary so popular, and every cultural creator should learn from its success.According to the passage, A Bite of China is _______.
| A．a book | B．a film |
| C．a newspaper | D．a TV program |
What can you find in A Bite of China?
| A．Relations between people and food. |
| B．Real lives of all Chinese people. |
| C．Patriotic stories of Chinese people. |
| D．processes of preparing food. |
From the passage, it can be inferred that ________.
| A．The documentary is so successful that no one can surpass (超越) it. |
| B．Different people can get different messages from the documentary. |
| C．The documentary should have shown China’s splendid food culture. |
| D．Many art works fail to reflect (反映) reality and high technology. |
The main idea of the last paragraph is that ________.
| A．Director’s respect and love for food. |
| B．The secret of the documentary’s success. |
| C．The influence of the documentary. |
| D．The popularity of the documentary. |

The best way to cure sadness is not shopping, according to a recent study. The so-called shopping method has become common practice these days, but that can put your wallet under a lot of pressure. So if you are sad and feel like shopping, don’t!
According to the recent study, sadness leads to self-focus (自我为中心的) thinking. In other words, sad people are willing to spend more money on the same thing than calm people.
"It is the result of sadness and self-focus, and it turns out that sadness leads to an increase in self-focus," said Cynthia Cruder. "What we think is that sad and self-focused people are feeling pretty bad about themselves, and one way to deal with this is buying material goods."
In a perfect situation, when you know you are sad, you should avoid(避免) making decisions and spending money. Sounds simple? Sadly, it is not. Most people don’t even know they’re sad, the study shows, and they are not aware that their feelings influence their decisions.
What to do? The study showed that those who watched a tragedy(悲剧) were more likely to spend three times more money for a simple bottle of water than those who watched a comedy. The solution: well, for starters, don’t go shopping! If you can’t help it, it is probably better to see a doctor.When you can’t help shopping after feeling sad, you’d better _______.
| A．talk to your friends |
| B．go to the store directly |
| C．go to bed and rest |
| D．go to hospital and get checked out by a doctor |
We can learn from the passage that________.
| A．sad and self-focused people are poor |
| B．sad people make important decisions easily |
| C．tragedies may make people buy more expensive goods |
| D．sad people are less confident than calm people |
What would be the best title for this passage?
| A．The Loss of Money Caused by Sadness |
| B．Shopping is Not the Best Way to Cure Sadness |
| C．A Study About How to Stay in a Good Mood |
| D．How to Make Decisions When You Are Sad |

Many people turn to doctors or self-help books, but they ignore a powerful thing that could help them fight illness: their friends.
Researchers are only now starting to pay attention to the importance of friendship in health. A 10-year Australian study found that old People with a large circle of friends. A large 2007 study showed an increase of nearly 60 percent in the risk （危险） for obesity （肥胖） among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could improve brain health as we age.
“In general, the role of friendship in our lives isn’t well realized,” said Rebecca, a professor at the University of North Carolina. “Friendship has a bigger effect on our psychological （心理的） health than family relationships. ”
While many friendship studies are about the close relationships of women, some research shows that it can do good to men too. In a six-year study of 736 middle-aged men, having friendships reduces the risk of heart attack. Only smoking was as important a risk factor （因素） as having little social support.
Exactly why friendship has such a big effect isn’t entirely clear. While friends can send a sick person to the hospital or pick up medicine, the advantages go well beyond physical help. Friendship clearly has a big psychological effect. “People with stronger friendships feel like there is someone they can turn to,” said Karen, a doctor. “The message of these studies is that friends make your life better. ”The three studies in paragraph2 show that .
