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 _______.

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 _______.

movements           B. wires        C. brain signals        D. Scientists

Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here’s how.

1) Plan your time carefully. When you plan your week, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don't forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

2) Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television! When you sit down to study, concentrate on the subject.

3) Use your time in class properly. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what the teacher says.

4) Study regularly. When you get home from school, go over your notes, especially the important points that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read that material will become more meaningful, and you will remember it longer.

5) Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don't pass a test, so don't be overly worried.

There are other methods that might help you with your studying. You will probably discover many others after you have tried these.

There is a lot of misunderstanding about studying. Most students have not been taught the principles behind really effective working. Imagine a graph showing the amount a person learns against the number of hours he works in a day. If he doesn’t do any work, he learns nothing (point 0). If he does an hour’s work he learns a certain amount (point 1). If he does two hours’ work he learns about twice as much (point 2). If he does more work he’ll learn still more (point 3). However, if he tries to do twenty-three and a half hours’ work in a day, he will be so tired that he’ll hardly remember anything: what he learns will be very little (point 4). If he did less work he’d learn more (point 5).

Now whatever the exact shape of the graph’s curve(曲线), made by joining these points, it must have a high point. Point “X” is the very maximum anyone can learn in the day. And this represents the optimum(最适度), the best, amount of work to do. It is the best possible compromise between adequate time at the books and fatigue(劳累). Fatigue is an absolutely real thing; one can’t escape it or ignore it. If you try to ignore it and press yourself to work past the optimum, you will only get on this downward slope and achieve less than the best – and then become very tired and lose your power of concentration.

The skill in being a student consists of getting one’s daily study as near the optimum point as possible. I cannot tell you what the optimum is. It differs with the type of work, it differs from person to person, and even in the same person it varies from week to week. You must try to find your own. Every day you study, bear this principle of the optimum in mind. When you feel yourself getting fatigued, if you find yourself reading the same paragraph over and over again and not taking it in, that’s a pretty good sign you’ve reached your highest point for the day and should stop. Most ordinary students find their optimum at five hours a day. Yours may be a little more or a little less – but if you get in five hours’ good work a day, you will be doing well.

Now, what are you doing with yourself when you aren’t working? Before examinations some students do nothing at all except sit in a chair and worry. Here is another misunderstanding. People often think that the mind works like the body; it does not. If one wanted to save one’s physical energy in order to cut the maximum amount of firewood, one would lie flat on a bed and rest when one wasn’t chopping. But the mind cannot rest. Even in sleep you dream, even if you forget your dreams. The mind is always turning. It gets its relaxation only by variety. That is what makes the mind rest.

When you’ve finished your optimum number of hours you must stop. You must not then sit around in the chair thinking about the work – that only tires without any learning. You must get out and do something. It doesn’t matter what – anything so long as you are actively doing something else but work.
