Thoughts claim our attention continuously, and waste our time and energy on unimportant and useless matters. They actually rule our life. We have become so used to this slavery, that we take it for granted, and have become unconscious of this habit, except on certain occasions.
While breathing, we do not need to pay attention to each inhalation and exhalation. We become conscious of the process of breathing only when we have some difficulty with breathing, such as when our nose is blocked, due to a cold, or when we are in an unventilated(不通風(fēng)的) room.
It is the same with thinking. We become conscious of the constant onslaught of our thoughts, and of our inability to calm them down, only when we need to concentrate, solve a problem or study. We are also aware of them when we have worries or fears.
Look at the following familiar situation. You need to study something for an exam. You sit comfortably on the sofa with the book in your hands and start reading. After a while you feel hungry and go to the kitchen to eat something.
You return to read, and then hear your people talking outside. You listen to them for several moments and then bring your attention back to the book.
After a while you feel restless and switch on the radio to listen to some music. You continue to read for a little while, and then remember something that happened yesterday, and you start thinking about it.
When you look at your watch, you are amazed to find out that one complete hour has passed and you have hardly read anything. And at this time, you feel you’re thinking.
This is what happens when one lacks concentration. Imagine what you could have accomplished if you could control your attention and focus your mind!
【小題1】When can you feel you are thinking?
| A．While breathing. | B．While not reading. |
| C．When you need to concentrate. | D．When you waste your time. |
| A．To explain the course of thinking awareness. |
| B．To show how to get ready for an exam. |
| C．To present an example of concentration. |
| D．To emphasize the importance of reading. |
| A．In a guidebook of natural science. |
| B．In the front page of a newspaper. |
| C．In an advertisement part of a magazine. |
| D．In the section of psychology of a magazine. |
| A．the relationship between thoughts and breathing |
| B．how people’s thought and mind work |
| C．what happens when one wants to think |
| D．the ways to increase your thought |
【小題1】C

解析試題分析：文章用呼吸的過程來解讀人們的思維過程。然后用復(fù)習(xí)迎考的事例進一步論證，指出“如果你集中注意力去進行思考，相像一下你本來可以完成的事情有多少”。告誡人們：要集中注意力去進行思考，而不是讓思考不斷剝奪我們的注意力，把時間和精力浪費在雞毛蒜皮的無用的事情上。
【小題1】C細(xì)節(jié)理解題。根據(jù)第三段We become conscious of the constant onslaught of our thoughts, and of our inability to calm them down, only when we need to concentrate, solve a problem or study.可知答 案為C。
【小題2】A推理判斷題。根據(jù)四五六七段可知，作者舉例是為了證明第三段作者的觀點，即只有在你想要集中精力時你才會感覺到你在思考，故答案為A：為了解釋你產(chǎn)生思考意識的過程。
【小題3】D推理判斷題。文章主要講在什么情況下人們會意識到自己在思考，而思考的過程屬于心理活動的過程，所以本文應(yīng)該選自心理學(xué)雜志。
【小題4】B主旨大意題。文章用呼吸的過程來解讀人們的思維過程。然后用復(fù)習(xí)迎考的事例進一步論證。故文章的主要講的是：集中注意力才能進行思考，實際就是講的“人們的心里思維是如何進行的”。

Many people think of the brain as a mystery.They don't know much about intelligence and how it works.When they do think about what intelligence is，many people believe that a person is born smart，average，or dumb—and stays that way in the whole life.But new research shows that the brain is more like a muscle—it changes and gets stronger when you use it.And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights，your muscles get bigger and you get stronger.A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time.That's because the muscles become larger and stronger with exercise.And when you stop exercising，the muscles shrink and you get weaker.That's why people say “Use it or lose it！”
But most people don't know that when they practice and learn new things，parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex(皮層)of the brain are billions of tiny nerve cells，called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things，these tiny connections in the brain actually multiply and get stronger.The more you challenge your mind to learn，the more your brain cells grow.Then，things that you once found very hard or even impossible to do—like speaking a foreign language or doing algebra(代數(shù))—seem to become easy after learning them for a period of time.The result is a stronger，smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals'brains.They found out that animals that lived in a challenging environment were more perspicacious—they were better at solving problems and learning new things.
【小題1】According to the first paragraph，________.
| A．the function of our brain is like that of the muscle |
| B．until now it's impossible to explain the brain's mystery |
| C．many people believe one's intelligence is naturally determined |
| D．one's brain grows stronger as the age increases |
| A．using the brain |
| B．connecting things in your brain |
| C．lifting weights |
| D．doing research about the brain |
| A．Strong. | B．Smart. |
| C．Popular. | D．Active. |
| A．the differences between animals'brains and humans'brains |
| B．the relation between human brains and muscles |
| C．scientists' findings about animals' brains |
| D．how to make your brain smarter through self?development |

Electrical devices(儀器)could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking , British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks ,the device captures energy each time the person slows down. To do this ,the device helps with the slowing sown movement of the leg, the movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also he used in hospitals to operate heart pacemakers(起博器), it could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy, but the researchers hope to make a lighter, less costly version, An improved version should be ready in one year.
The developers hope the device will one day help developing countries; nearly twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania, He created a bag carried on a person’s back that also produces power from walking. The knee device does not produce as much electricity as the bag, but the bag requires the walker to carry a load of twenty to thirty kilograms.
【小題1】. The second paragraph mainly talks about
| A．who developed the device | B．how the device works |
| C．several possible uses for the devices | D．how much electricity the device can produce |
| A．It is too heavy for the walker to bear | B．It is too complex for people to use |
| C．It is too expensive for most people to afford | D．It will slow down one’s walking speed |
| A．produces power without adding more loads to the walker |
| B．can produce more power in a much shorter time |
| C．needs to be equipped with a battery |
| D．can help the walker walk faster |
| A．help housewives operate the washing machine |
| B．make it much easier for us to go online |
| C．produce more electricity than that invented by Larry Rome |
| D．be applied in medical fields to operate heart pacemakers |

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron that is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
【小題1】A good title for this reading passage is______.
| A．Popeye the Sailor | B．The Truth About Spinach |
| C．A Mistake with Numbers | D．Folic Acid Makes You Strong |
| A．They thought spinach made them strong. |
| B．They thought Popeye was funny. |
| C．Spinach had a lot of iron. |
| D．People liked folic acid. |
| A．made Popeye strong |
| B．was a green vegetable |
| C．had less iron than other green vegetables |
| D．had more iron than other green vegetables |
| A．iron | B．folic acid | C．spinach | D．exercise |
| A．something in food | B．a(chǎn) vegetable | C．dangerous | D．a(chǎn) certain kind of spinach |

Online Communication
In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letter. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication.
But a story about online communication changed my mind.
An old man, who suffered a lot from Parkinson’s disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard.
I, therefore, managed to get an E-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities（能力） that few other products can match.
E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn’t want to have a face-to-face talk with your manager, you might talk with him through E-mail even if you are in the same office.
Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could easily spend half a day clearing junk ads.
Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I’m sure there is and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting… even in the world of modern communication.
As I listen to the sound of the modem(調(diào)制解調(diào)器), I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life.
【小題1】What is the most probable meaning of the underlined word “junk” in paragraph6?
| A．old and useless | B．New and useful | C．Short but valuable | D．Long but clear |
| A．It should replace old-fashioned letters completely. |
| B．It is perfect and always does good to you. |
| C．It is extremely useful and convenient, but it may be inconvenient or even harmful. |
| D．It does more harm than good. |
| A．The sound of the modem. | B．His own illness. |
| C．The changing of his life. | D．A sick old man’s experience. |
| A．they are convenient and popular though they are slow |
| B．they help to keep the friendly relationship between people |
| C．most people cannot keep up with the development of technology |
| D．modern means of communication does too much harm |
| A．With the help of his computer. | B．By writing letters with his pen. |
| C．By making telephone calls. | D．By visiting them regularly. |

We probably all know people, either at work or in our personal lives, who are really good listeners. No matter what kind of situation we’re in, they always seem to know just what to say and how to say it so that we’re not offended(被冒犯) or upset. We probably also know people who are masters at managing their emotions(情緒). They don’t get angry in stressful situations. Instead, they have the ability to calmly look at a problem and find a solution. They take criticism(批評) well, and they know when to use it to improve their performance.
People like these who have a high degree of emotional intelligence, or EI(情商). They know themselves very well, and they’re also able to sense the emotional needs of others.
As more and more people accept that emotional intelligence is just as important to professional success as technical(專業(yè)的) ability, companies are increasingly using EI when they hire and promote(提拔) someone. For example, one large cosmetics (化妝品) company recently changed their hiring process for salespeople to choose candidates(被選的人) based on emotional intelligence. The result? Salespeople hired with the new system have sold, on average, $91,000 more than salespeople selected under the old system.
Emotional intelligence is the ability to recognize your emotions, understand what they are telling you, and realize how your emotions affect people around you. Emotional intelligence also involves your perception (洞察力) of others: when you understand how they feel, this allows you to manage relationships more effectively.
People with high emotional intelligence are usually successful in most things they do. Why? Because they are the ones that others want on their team. When people with high EI send an email, it get answered. When they need help, they get it. Because they make others feel good, they go through life much more easily than people who are easily angered or upset.
The good news is that emotional intelligence can be taught and developed. Many books and tests are available to help you determine your current EI, and identify where you may need to do some work.
【小題1】According to the passage, we’re all probably impressed by people who _____.
| A．a(chǎn)re ready to help others |
| B．a(chǎn)re very successful in their lives |
| C．have high emotional intelligence |
| D．know how to control their temper |
| A．stress the importance of emotional intelligence |
| B．speak highly of its new salespeople |
| C．show its effective hiring system |
| D．explain what improvements it has made |
| A．your emotions | B．people around you |
| C．effective relationships | D．your opinions of others |
| A．They are usually good speakers. |
| B．They are born to be sensitive and intelligent. |
| C．They don’t get angry in any situation. |
| D．They can understand others’ feelings well. |
| A．What emotional intelligence is. |
| B．How emotional intelligence can be improved. |
| C．Many books on emotional intelligence. |

One reaction to all the concern about tropical deforestation（毀林） is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
【小題1】The underlined word "synthetics" probably means_________.
| A．natural rubber | B．tropical materials |
| C．man-made material | D．commercial rubber |
| A．The forests are losing their function in turning carbon dioxide into oxygen. |
| B．Many of our daily uses are related to the tropical forests. |
| C．Tropical plants can be used to make industrial products. |
| D．High carbon dioxide levels will make the earth warmer. |
| A．puzzling | B．cold | C．supporting | D．opposed |
| A．Tropical Forests | B．The Value of Tropical Forests |
| C．Tropical Forests and Our Life | D．The Greenhouse Effects |

Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said. “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.” “Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen: “ENTER NAMES
VOYAGER 1:…
VOYAGER 2:…”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED (自動回收程序已啟動).”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒) , until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.

It’s you and I who are to blame for the state of the earth. No question about it. It’s our life-style that is threatening life on Earth, so we must make the changes. The good news is that many of those changes are really quite simple, even enjoyable, but for every careful step we take as individuals, we must press government and industry to take a big step on our benefit. And we must start now. Tomorrow’s too late.
My aim this year is to persuade as many of my friends and colleagues as possible to choose the train, and leave their cars behind too. My gardens have been pesticide(殺蟲劑)–free zones for years and I enjoy seeing more wildlife on my doorstep as a result; I’ve tried to reduce my contribution to water pollution too, by using environment-friendly, phosphate(磷)–free washing powder , and by no longer thinking of the toilet as a suitable waste-disposal(處理) point .
I ran after a young lady through town recently to give her back the piece of paper she had carelessly thrown away. She disappeared into a shop, and when I followed her inside and made my presentation, she was doubly embarrassed--she worked there, and the boss gave her a ticking–off too. I’ve started asking fellow drivers at gas stations why they aren’t using unleaded (無鉛的) petrol . These are small things, but we have to start somewhere, and every little does help.
【小題1】We can learn from the first paragraph that____________.
| A．you and I are responsible for looking after the environment |
