Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it，whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further： mirror neurons not only appear to explain physical actions y they also tell us that there is a biological basis for the way we understand other people.
Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example ："The hand took hold of the ball" ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).
Any problems with mirror neurons may well result in problems with behavior. Much researeh suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.
Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互动）.Indeed, it may turn out to be the equivalent (相等物）for ncurosciencc of what Einstein"s theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does--well，perhaps you"ll understand why.

小题2:词义猜测题。根据下文的perform和本句的含义可知“如果他们给人们一些句子来听，那么他们就会发出同样的神经元和进行一些行为动作一样。所以划线部分单词意为“发出”和set off近义。
小题3:推理判断题。根据最后一段第一句Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互动）可知答案。
小题4:主旨大意题。根据第一段的疑问句引出神经元和下文解释神经元对于人类行为和互动提供更多的信息可以知道本文主要告诉我们mirror neurons的作用，D项能概括文章大意。
【长难句解析】
Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it，whether or not we actually perform the same action.
简单地说，神经元的存在说明每当我们看到别人做其他事情的时候，无论我们是否想表演同样的动作，我们的大脑就都会模仿。
本句中的suggest意为“说明“，every time“每当…的时候”，whether or not“无论是否”。

First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle (角度) to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you are tacking, you must always keep the sail inside the boat.
小题1:What should you consider first while sailing?
| A．Sailors’ strength. | B．Wave levels. |
| C．Wind directions. | D．Size of sails. |
| A．The boat. | B．The wind. | C．The sail. | D．The angle. |
| A．Move in a straight line. | B．Allow the sail to flap. |
| C．Lower the sail. | D．Tack the boat. |
| A．In a popular magazine. | B．In a tourist guidebook. |
| C．In a physics textbook. | D．In an official report. |
Sea turtles do not have teeth but use their jaws （下巴）to eat. Their sense of smell is excellent. Their eyesight underwater is good, but they have near-sighted eyes out of water. Their special bodies make them adapt to life at sea. However, sea turtles maintain（保持） close ties to land.
Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries（谜） still remain.
Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance. It is believed that some species can live for over 100 years.
小题1:Which of the following statements is NOT true about sea turtles?
| A．They don’t use teeth to eat. |
| B．They have a good sense of smell. |
| C．Sea turtles are more adaptable to life at sea. |
| D．Different species have different shells. |
| A．good eyesight | B．bad eyes |
| C．excellent eyes | D．poor eyesight |
| A．Why do female turtles lay eggs on land? |
| B．Why can’t people tell how old a sea turtle is from its appearance? |
| C．Where do the baby turtles usually go? |
| D．Do sea turtles grow very fast? |
| A．Mysteries About Sea Turtles |
| B．Baby and Female Sea Turtles |
| C．The Growth of Different Sea Turtles |
| D．The Characteristics（特点） of Sea Turtles |
Making an efficient icebox as not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary(未发展的). The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation(绝缘) and circulation needed for an efficient icebox.
But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price(高价) for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.
小题1:Where was ice used after the Civil War?
| A．In refrigerating freight cars and households. |
| B．In hotels, taverns and hospitals |
| C．In families of New York, Philadelphia, and Baltimore. |
| D．In fresh meat, fish and butter by city dealers. |
| A．Keeping the ice from melting |
| B．Knowledge of the physics of heat. |
| C．Balance of insulation and circulation |
| D．Making efforts to reduce the use of ice |
| A．the deveopment of icebox |
| B．the theoretical foundation of icebox |
| C．the wrong ideas about icebox |
| D．the way of using icebox |
| A．Thomas Moore is the inventor of modern fridge |
| B．The butter produced by Thomas Moored is better in quality than other famers’ |
| C．Knowledge of the physics of heat plays an important part in inventing a good icebox |
| D．Before 1880, most of the sold ice was used for family use. |
| A．to sell their produce at high price |
| B．to go home earlier |
| C．to keep their produce fresh |
| D．to win more customers than their competitors |
What can explain and solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going—and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.
小题1:Man cannot prevent the world from being polluted mainly because______.
| A．the population of the world is decreasing fast |
| B．people use too many man-made materials |
| C．we have more and more industry |
| D．we are producing more cars, trucks and buses |
| A．Industry. | B．Health. |
| C．Clean air. | D．The future of the children. |
| A．man knows where the society is going |
| B．people do not welcome the rapid development of modern society |
| C．man can do little about the problem of pollution |
| D．the writer is worried about the future of our society |
| A．they want very much to find well-paid jobs |
| B．they are anxious to enjoy the achievements of our society |
| C．they have become tired of their homeland |
| D．they have a strong wish to become industrial workers |
The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site.
Web sites offering cheap services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they thought they bought.
The thieves then go shopping with your card number--- or sell the information over internet.
Computers hackers（黑客） have broken down security（安全） systems raising questions about the safety of cardholder information. Several months ago, 25,000 customers of CD Universe, and on-line music retailer（批发商）, were not lucky. Their name, addresses and credit-card numbers were posted on a web site after the retailer refused to pay US $157,828 to get back the information.
Credit-card firms are now fighting against on-line fraud. Master-card is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated.
Ask about your credit-firm’s on-line rules. Under British law, cardholders are responsible for the first US $78 of any fraudulent spending.
And shop only at secure sites: Send your credit-card information only if the web site offers advanced secure system. If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The web site address may also start the extra “s” stands for secure.
If you still have any doubt, give your credit-card information over the telephone.
Keep your password safe: Most on-line sites require a user name and password before placing an order. Treat your password with care.
小题1:What do most people worry about the Internet according to this passage?
| A．fraud on the Internet | B．computer hackers |
| C．illegal web site | D．shopping on line |
| A．1 | B．2 | C．3 | D．4 |
| A．You can go to the website and buy it without doubt. |
| B．Send your credit card information as soon as the web asks you to do so. |
| C．Give your credit card information over telephone if you have doubt. |
| D．Don’t pay money until your TV set is sent to you. |
| A．Computer hackers sold the retailer’s information to a web site to get money. |
| B．A reliable website offers you an advanced secure system. |
| C．You can depend on the password to protect your information. |
| D．The on-line credit-card thieves stole your credit-card and paid with it. |
