The Next Frontier: Using Thought to Control Machines
Technologies are often billed as transformative. For William Kochevar, the term is justified. Mr Kochevar is paralysed below the shoulders after a cycling accident, yet has managed to feed himself by his own hand. This progress is partly thanks to electrodes, implanted in his right arm, which stimulate muscles. But the real magic lies higher up. Mr Kochevar can control his arm using the power of thought. His intention to move is in neural(神经的) activity in his motor region; these signals are detected by implants in his brain and into commands to activate the electrodes in his arms.
An ability to decode thought in this way may sound like science fiction. But brain-computer interfaces (BCIs) like the BrainGate system used by Mr Kochevar provide evidence that mind-control can work. Researchers are able to tell what words and images people have heard and seen from neural activity alone. Information can also be encoded and used to stimulate the brain. Over 300, 000 people have cochlear(耳蜗的) implants, which help them to hear by sound into electrical signals and sending them into the brain. Scientists have "" data into monkeys heads, instructing them to perform actions via electrical pulses.
As our Technology Quarterly in this issue explains, the pace of research into BCIs and the scale of its ambition are . Both America's armed forces and Silicon Valley are starting to focus on the brain. Facebook dreams of thought-to-text . Kernel, a startup, has $100m to spend on neurotechnology. Elon Musk has formed a firm called Neuralink; he thinks that, if humanity is to survive the arrival of artificial intelligence, it needs an upgrade. Entrepreneurs imagine a world in which people can communicate using thoughts, with each other and with machines, or acquire abilities, such as hearing at very high frequencies.
These powers, if they ever materialise, are decades away. But well before then, BCIs could open the door to wonderful new . Imagine stimulating the visual region to help the blind, making new neural in stroke victims or monitoring the brain for signs of depression. By turning the firing of neurons into a resource to be used, BCIs may change the idea of what it means to be human.
By the end of the 2020s, almost a quarter of Japan's population will be over 65. So, to help society deal with an ageing population, a Tokyo company has developed an "Ageing Suit". As a journalist, I went along to try it out.
The few hours I spent at the "Wonderful Ageing Club" were, it has to be said, rather depressing. I, dressed in the club's "ageing suit", was transformed rather too quickly from a relatively healthy 36-year-old to an 80-year-old.
First, I had to put on restrictive bindings (捆绑) over my knees, elbows, ankles and feet, which made me unable to move normally. The ladies of the Wonderful Ageing Club, however, were still far from finished. Assuring me that their suit had been carefully designed on the basis of scientific research into the exact effects of ageing, they next applied a pair of special gloves to my hands to make grabbing much more difficult. A number of weights were attached to my body to create the sensation of weakened muscles. A pair of earplugs muffled my hearing and my vision grew rather clouded as a result of my special glasses. This completed an imprisonment in a body more than twice my own age. Now I found myself clumsily getting my way through such newly difficult tasks as sitting down on a chair and then standing up again or opening a can of Coke.
But what is the purpose of this ageing suit? The company claims that it gives a very accurate representation of what being old is really like, and that, when it comes to planning for the future, that experience will be of great value. They hope to see whether the products or services they offer really do meet the needs of the elderly.
What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live?
We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle. Mental exercise is particularly important for young children. Many child psychologists think that parents should play with their children more often and give them problems to think about. If on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent. According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive things to their children, such as “That was a very clever thing you did.”or“”
A. A healthy body contributes to one's intelligence.
B. Parents should also be careful about what they say to young children.
C. What people want to express is like this.
D. The children are then more likely to grow up bright and intelligent.
E. It needs exercise.
F. You are such a smart child.
G. These are very old questions and the answers to them are still not clear.
A popular saying goes, “Sticks and stones may break my bones, but words will never hurt me.” However, that's not really true. Words have the power to build us up or tear us down. It doesn't matter if the words come from someone else or ourselves — the positive and negative effects are just as lasting.
We all talk to ourselves sometimes. We're usually too embarrassed to admit it, though. In fact, we really shouldn't be because more and more experts believe talking to ourselves out loud is a healthy habit.
This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying “Good job!”
Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner. Or harsh(刻薄的)and critical language will most likely cause the clerk to be defensive.
Words possess power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.
Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem(自尊)and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.
The capital of a country is often a very populated city where much history has been made due to the high-level political and economic functions that occur there. However, sometimes government leaders decide to move the capital from one city to another. Capital relocation has been done hundreds of times throughout history. The ancient Egyptians, Romans, and Chinese changed their capital frequently.
Some countries choose new capitals that are more easily defended in a time of invasion (侵略) or war. Some new capitals are planned and built in previously undeveloped areas to promote development. Countries sometimes change their capital because they expect some type of political, social, or economic benefit. They hope and expect that the new capitals will surely develop into cultural treasure and hopefully make the country a more stable place.
Here are capital relocations that have occurred in approximately the last few centuries.

The art of Palmistry (手相术)
Palm reading, or palmistry, is the ancient art of studying the lines on the palm of the hand to describe a person’s character and foretell future events in a person’s life.
To study a person’s character and future, a palm reader looks carefully at the three main lines on the active hand (the one a person writes with). The reader usually looks first at a person’s Life Line. This begins under the index finger, and goes down towards the wrist. This line describes the way a person lives his or her life. A person with a deep Life Line is energetic and competitive. If a person has a faint line, he or she is more of a thinker than a doer.
The Heart Line runs across the hand, just below the fingers. This line describes one’s emotions or feelings. A person with a deep Heart Line is a peace maker. Family is important to this person. Those with a faint line do not like to be alone. They are often controlled by their emotions.
The Head Line is below the Heart Line. It describes how a person thinks. A person with a long Head Line thinks about things very carefully. Those with a short Head Line are very decisive. A person with a deep Head Line is clever and talkative. Those with a faint Head Line are often messy, but very creative.
Palm readers believe that these lines and marks on the hand can tell us something about our personalities. Try the test on yourself. Do you agree?

Close your eyes for a minute and imagine what life would be like if you had a hundred dollars less.Also imagine what it would be like spending the rest of your life with your eyes closed.Imagine having to read this page,not with your eyes but with your fingertips.
With existing medical knowledge and skills,twothirds of the world's 42 million blind should not have to suffer.Unfortunately,rich countries possess most of this knowledge,while developing countries do not.
ORBIS is an international nonprofit organization which operates the world's only flying teaching eye hospital.ORBIS intends to help fight blindness worldwide.Inside a DC8 aircraft,there is a fullyequipped teaching hospital with television studio and classroom.Doctors are taught the latest techniques of bringing sight back to people here.Project ORBIS also aims at promoting peaceful cooperation(合作) among countries.
ORBIS tries to help developing countries by providing training during threeweek medical programs.ORBIS has taught sightsaving techniques to over 35,000 doctors and nurses,who continue to cure tens of thousands of blind people every year.ORBIS has conducted 17 plane programs in China so far.For the seven to ten million blind in China,ORBIS is planning to do more for them.At the moment an ORBIS team is working on a longterm plan to develop a training center and to provide eye care services to Shanxi Province.ORBIS needs your help to continue their work and free people from blindness.
For just US $38,you can help one person see;for $380 you can bring sight to 10 people;$1,300 helps teach a doctor new skills;and for $13,000 you can provide a training program for a group of doctors who can make thousands of blind people see again.Your money can open their eyes to the world.Please help ORBIS improve the quality of life for so many people less fortunate than ourselves.
