Talking to yourself may seem a little shamefu...

Talking to yourself may seem a little shameful. According to the well-known saying, talking to yourself is the first sign of madness, 1. Talking to ourselves, whether out loud or silently in our heads, is a valuable tool for thought.

Far from being mentally ill, self-talk allows us to plan what we are going to do, manage our activities, regulate our emotions and even create a description of our experience.2.

As children, according to the Russian psychologist Lev Vygotsky, we use private speech to regulate our actions in the same way that we use public speech to control the behavior of others.3. Psychological experiments have shown that the private speech can improve our performance on tasks ranging from judging what other people are thinking to sorting images into categories. One recent study suggested that self-talk is most effective when we address ourselves in the second person, as “you” rather than “I”.

4. If you want proof, turn on the sports channel. You’re certain to see an athlete or two cheering themselves up with a bitter phrase or scolding themselves after a bad shot.

Conduct a dialogue with ourselves.5. The private speech seems to be a particularly good way of solving problems and working through ideas. The to-and-fro between different points of view means our thoughts can end up in expected places, just like a regular dialogue can, and might turn out to be one of the keys lo human creativity.

A.What is private speech?

B.Bui there is no need for embarrassment.

C.Psychologists refer to this as private speech.

D.Ask questions of the self and provide answers.

E.We do a lot of private speech when we are young.

F.As we grow older, we make the private speech become the way of blinking,

G.Although the private speech is effective, we never entirely put away the out-loud speech.

Helping yourself to a cup of coffee may seem like a small, everyday thing. But it is not the case if you are quadriplegic (四肢瘫痪). Quadriplegics have lost the use of all four limbs. Thanks to a project organized by John Donoghue of Brown University, in Rhode Island, and his colleagues, quadriplegics have hope.

One of the participants in his experiments, a 58-year-old woman who is paralyzed and unable to use any of her limbs, can now pick up a bottle containing coffee and bring it close enough to her mouth to drink from it using a straw. She does so using a thought-controlled robotic arm fixed to a nearby stand. It is the first time she has managed something like that since she suffered a stroke, nearly 15 years ago.

Arms are more complicated pieces of machinery than legs, so controlling them via electrodes (多波段电极) attached to the skin of someone’s scalp (头皮) is not yet possible. Instead, brain activity has to be recorded directly. And that is what Dr Donoghue is doing. Dr Donoghue and his team have had small, multichannel electrodes implanted in the parts of the motor cortexes (运动皮质) of participants’ brains associated with hand movements.

Dr Donoghue and his team decoded signals from their participants’ brains as they were asked to imagine controlling a robotic arm making present movements. The woman and other volunteers were then encouraged to operate one of two robot arms by thinking about the movements they wanted to happen. When the software controlling the arms detected the relevant signals, the arms moved appropriately. The arm that the woman used to help herself to a drink is a lightweight device developed by DLR, German’s Aerospace Centre, as part of its robotics program.

Dr Donoghue and his colleagues have thus shown that a mechanical arm can be controlled remotely by the brain of a person with paralysis. Controlling an arm that is attached to the individual’s body will be trickier, but in time even that may be possible. In the meantime, a robotic arm attached to a wheelchair will be a real soon.

1.What does the underlined word “that” in Paragraph3 refer to?

A.Controlling a robotic arm via electrodes attached to the scalp.

B.Recording the activity of brain and implanting electrodes.

C.Controlling a robotic leg via electrodes attached to the scalp.

D.Controlling a mechanical arm attached to the individual’s body.

2.Which statement may the author agree with?

A.Thanks to the research by Dr Donoghue and his colleagues, a paralyzed woman can get herself a drink.

B.The woman in the experiment drinks a bottle of coffee with a robotic arm attached to her scalp.

C.The woman is encouraged to control the mechanical arm by moving her body.

D.The robotic arm the woman used is remoted by DLR.

3.What’s the author’s attitude to the future of the robotic arm attached to quadriplegic?

A.Pessimistic. B.Objective.

C.Controversial. D.Optimistic.

4.What’s the main idea of the text?

A.Quadriplegics can use the artificial limbs developed by Dr Donoghue and lead a good life by themselves.

B.The newly-developed thought-controlled robotic arms can help the paralyzed in their daily life.

C.Scientists have invented a kind of robotic arm attached to the individual’s body.

D.A quadriplegic can be on his feet again due to the new invention.

How would you like to teach yourself, rather than have teachers? According to the UK’s Department of Education and Skills, students will teach themselves in the schools of the future. This means that there will be no more problems such as finding enough teachers.

Estelle Morris, the UK Education Secretary, opened the 2002 Education Technology Conference in London recently. To start the conference, she presented a video showing a computer—generated model of the school of tomorrow.

Greater use of computer technology and classroom assistants will help students develop their own way of learning, Morris said. She added that this is a more exciting as well as a more interesting way of learning.

At the same time, teachers will be “freed from their traditional role as the source of all knowledge”.

Children of all abilities will “form the curriculum(课程)around their individual needs.” They will “learn in their own time, at their own speed and in their own environment”.

At home or at school, they will follow their learning programmes by looking at online libraries and watching lessons by world-class teachers and subject experts.

Instead of going on field trips, students will use virtual reality. If they don’t understand something, they can ask other students—“take part in virtual communities with learners with similar needs”—or e-mail their teachers. They will hand in their work electronically to be “auto-marked”.

The classroom of the future is fast becoming a reality.

And the Department of Education will soon produce a guide to help schools adapt buildings for new technology, Morris said. These ideas are based on the UK government’s plan to create an education system that provides students with a strong grounding of knowledge and skills at primary school level. And provides the chance for students to develop their individual skills at secondary school level.

1.According to the UK’s Department of Education and Skills, the school of the future will ______.

A. cause more problems such as being able to find enough teachers

B. set no homework and no tests for students

C. make good use of the computer technology and classroom assistants

D. enable students to learn by themselves without teachers

2.Estelle Morris thinks that computer technology does good to teachers in ________.

A. helping students develop their own way of learning

B. enabling students to experience interesting and exciting ways of learning

C. providing students with knowledge of all sorts

D. not being considered the source of various knowledge

3. If the students do not understand something, they can _______.

A. go on a field trip

B. go to ask their teachers to help them

C. send e-mail to ask for a teacher’s help

D. have a look at other learners’ homework

4. If s a student is under the UK’s newly-developed education system,he will be ________.

A. provided with a basic knowledge from the beginning

B. given more knowledge at primary school level

C. helped to use computers better

D. supplied chance to develop their basic skills

高三英语阅读理解困难题查看答案及解析

Whether or not your mouth is moving right now, you are talking to yourself. As you read these words, your facial muscles are having quick, invisible movements, sounding out the words so you can actually hear them in your head. This kind of speech is called "subvocalization", and unless you're a speed-reader who has trained yourself out of this habit, you're doing it every time you read or even imagine a word.

Now, MIT researchers want to use those subvocalization to know what's in your mind and translate it into digital orders, using a wearable smart headset called AlterEgo. The headset combines human and machine in some ways.

According to the MIT Media Lab, the device would allow users to send silent orders to the headset simply by thinking of a word. A neural (神经的) network would translate the muscle movements to speech and do the user's orders—totally hands-and-voice-free. Let's say you want to ask AlterEgo what time it is. First, you think the word "time". As you do, your facial muscles make micro-movements to sound out the word in your head. Electrodes(电极) on the headset record these movements and then send them to a computer. The neural network processes these signals the same way a speech-to-text program might, and responds by telling you the time.

In a small study, 10 volunteers read a list of numbers to themselves while wearing AlterEgo headsets. AlterEgo correctly got which numbers the participants were reading with an average accuracy of 92 percent. For comparison, Google's microphone-based speech-to-text translation service has an accuracy of about 95 percent.

“We basically can’t live without our digital devices,” said Pattie Maes, an MIT professor. "But at the moment, the use of those devices is causing some problems in our life. My students and I have been experimenting with new types of experience that enable people to still benefit from all the wonderful knowledge and services that these devices provide but do it in a way that lets them remain in the present.”

1.We can learn from the first paragraph that “ subvocalization” _______.

A. is less used in life now

B. is more effective than speed reading

C. refers to a silent way of reading something

D. means reading something in a detailed way

2.What does Paragraph 3 mainly talk about?

A. How AlterEgo works.

B. The production of AlterEgo.

C. The disadvantages of AlterEgo.

D. How to wear AlterEgo correctly.

3.The test in Paragraph 4 suggests that AlterEgo _______.

A. has good working performance

B. has become a popular digital product

C. works better than Googles similar service

D. is unable to complete complex tasks at present

高三英语单项填空简单题查看答案及解析

Turns out we aren’t good at walking and talking at the same time, according to a study of pedestrians （行人） on their cell phones．

Nearly one-third of pedestrians （29．8% ） were distracted （分散注意力） by their mobile  devices while crossing the street, say researchers of a study published online in the journal Injury Prevention．

Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident．

During the summer of 2012, scientists in Seattle, Wash． , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years．

They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so． Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person．

Overall, researchers found the most common distraction among pedestrians was listening to music （11．2%）, followed by text messaging （7．3%）, and using a handheld phone（6．2%）． But the most absorbing distraction was texting． Compared to pedestrians who were not distracted, those who were texting took 1．87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk． While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street．

Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians． And that danger may only climb, as the number of wireless devices has already exceeded the population of the United States． Last year, roughly 1,152 people wound up in the emergency room to treat injuries caused by using a cell phone or electronic device, the Consumer Product Safety Commission told the Associated Press in July． Those numbers may be underestimated, however, because patients may not always admit that they were using their phones along with other activities such as walking or driving when they were hurt．

1.The scientists did their study at the 20 crossroads in order to _____．

A．attract more attention                     B．see more injuries

C．record more samples                      D．find more pedestrians

2.According to the research, while crossing the street the most dangerous activity for apedestrian is _____．

A．talking on a phone                          B．texting messages

C．listening to music                           D．disobeying traffic lights

3.The underlined word "exceeded" is closest in meaning to "____"．

A．gone beyond                             B．greatly influenced

C．accelerated the increase of                 D．drawn the attention of

4.Which might be the best title of the passage?

A．Walk and don't Talk

B．Prevention of Distraction

C．Look both ways while crossing the street

D．Cell phones lead to injuries
