Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(独特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outfa
ce? Or did she throw away goods that she didn’t need in order to travel lighter?
Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildnes
s. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.
The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century. 
The ordinary woman’s leather shoe is considered unusual because ______.
| A．it was an important clue to life in the past |
| B．it was found on a famous trail |
| C．it at one time belonged to a VIP |

| A．they would not die of hunger and cold |
| B．the army would have enough food for fighting a war |
| C．they would change these goods with the Eskimos |
| D．the supplies would make Alaska rich |
No matter what happened to the woman who owned the shoe, ______.

B．she certainly dropped the shoe on purpose |
| C．her adventurous spirit is definitely admired |
| D．her other shoes were equally fashionable |
Rachel Carson，a wellknown nature author in America，was happiest writing about the strength and stability of natural systems.Her books mainly described the inter connectedness of nature and all living things.
Completing Silent Spring took Carson four years.First published in The New Yorker in June 1962，the book alarmed readers across America.It described how DDT entered the food chain and accumulated (堆积) in the fatty tissues of animals，including human beings，and caused cancer and genetic damage.
Carson begins by describing exactly these effects in the first chapter，creating strong images and drawing the readers in.As the book continues，she gives various examples of how insecticides(杀虫剂) are not only unsuccessful，but actually very costly and damaging.She also explains about the biological controls which are less expensive and much more efficient.
A single application on a crop，she wrote，killed insects for weeks and months，and not only the targeted insects but countless more，and remained poisonous in the environment even after it was washed out by rainwater.Carson concluded that DDT and other pesticides had definitely harmed birds and animals and had destroyed the entire world's food supply.The book's most famous chapter，A Fable for Tomorrow，described a nameless American town where all life—from fish to birds to apple blossoms to human children—had been “silenced” by the harmful effects of DDT.
The most important effect of Silent Spring，though，was a new public awareness that nature was so easily destroyed by human intervention(干预)．Rachel Carson had made a brave proposal：that，at times，technological progress is so basically at odds with(与……不一致) natural processes that it must be prevented.
What are Rachel Carson's books mainly concerned about?
| A．The relationship between man and nature. |
| B．The balance of natural systems. |
| C．The interconnection of nature and living things. |
| D．The pollution of the environment. |
According to the text，Silent Spring________.
| A．didn't draw the readers' attention when first published |
| B．mainly describes people's quiet lives in an American town |
| C．effectively tells people how to keep the balance of nature |
| D．showed the harmful effects of DDT on nature |
Rachel Carson thinks that the more efficient way to kill insects is to use ________.
| A．DDT |
| B．human controls |
| C．biological controls |
| D．technical progress |
The publication of Silent Spring makes people ________.
| A．understand the author's outstanding writing talent |
| B．realize the importance of technical progress |
| C．aware of the necessity of environmental protection |
| D．rethink the harmful effects of developing industry |
One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like “I was wrong about that，”and it is even harder to say，“I was wrong，and you were right about that.”
I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighborhood where I grew up，and he asked me if I remembered the egg cartons (箱子)．Then he related an incident and I began to remember clearly the incident he was describing.
I was about eight years old at the time，and I had gone into the store with my mother to do the weekly grocery shopping. On that day，I must have found my way to the dairy (乳品的) food department where the incident took place.
There must have been a special sale on eggs that day because there was an impressive display of eggs in dozen and halfdozen cartons. The cartons were stacked(堆放) three or four feet high.I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason，I decided it was up to me to put the display back together，so I went to work.
The manager heard the noise and came rushing over to see what had happened.When he appeared，I was on my knees examining some of the cartons to see if any of the eggs were broken，but to him it looked as though I was the criminal.He severely scolded me and wanted me to pay for any broken eggs.I protested(抗议)my innocence and tried to explain，but it did no good. Even though I quickly forgot all about the incident，obviously the manager did not.The author was ________ when he wrote this article.
| A．about 8 | B．about 18 |
| C．about 23 | D．about 15 |
Who should have been blamed for knocking off the stacks of cartons?
| A．The author. | B．The manager. |
| C．The woman. | D．The author's mother. |
When the manager scolded him，the author ________.
| A．was frightened and cried |
| B．felt the manager was right |
| C．did not say anything |
| D．tried to explain |
It can be inferred that the author ________.
| A．regrets arguing with the manager for what he didn't do |
| B．has forgiven the manager for what he did to him fifteen years ago |
| C．would like to tell people never to be fooled by an egg sale |
| D．expects the woman to say sorry to him for the mistake she made |
Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth?These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products of technological developments in the space, the chance to save ourselves might not exist.
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.What is the reason for exploring space based on Paragraph2?
| A．Humans are nature-born to do so. |
| B．Humans have the tendency to fight. |
| C．Humans may find new sources of food. |
| D．Humans don’t like to stay in the same place. |
The underlined word“spin-offs” in Paragraph 4 probably refers to______.
| A．survival chances | B．potential resources |
| C．unexpected benefits | D．physical possessions |
What makes it possible for humans to live on other planets?
| A．Our genetic makeup. |
| B．Resources on the earth.. |
| C．The adaptive ability of humans. |
| D．By-products in space exploration. |
Which of the statements can best sumun the passage?
| A．Space exploration has created many wonders. |
| B．Space exploration provided the best value for money. |
| C．Space exploration can benefit science and technology. |
| D．Space exploration may help us avoid potential problems on Earth. |
Consumers everywhere are faced with the same dilemma: given limited resources, what sorts of purchases are most likely to produce lasting happiness and satisfaction? Recent research has confirmed that experiential purchases tend to produce greater hedonic (享乐的）gains than material purchases.
The reason why experiences improve with time may be because it is possible to think about experiences in a more abstract manner than possessions. For example, if you think back to a fantastic summer from your youth, you might easily remember an abstract sense of warm sunshine and youthful exuberant (生气勃勃), but you're less likely to remember exactly what you did day-by-day.
Material possessions are harder to think about in an abstract sense. The car you bought is still a car, that great new jacket you picked up cheap is still just a jacket. It’s more likely the experience of that summer has taken on a symbolic meaning that can live longer in your memory than a possession.
Purchasing may have a negative impact on happiness because consumers often buy “joyless” material possessions, resulting in comfort but not pleasure. In general, people adapt to experiences more slowly than to material purchase. This can be seen in both negative and positive purchases: hedonic adaptation would result in a positive experience causing more happiness but a negative experience causing less happiness than the comparable material purchase with the same initial happiness level.
Experience, however, seems to be more resistant to these sorts of unfavourable comparisons. It is because of the unique nature of experience. It’s more difficult to make an unfavourable comparison when there is nothing directly comparable. After all, each of our youthful summers is different.
It’s well established that social comparisons can have a huge effect on how we view what might seem like positive events. One striking example is the finding that people prefer to earn $50,000 a year while everyone else earns $25,000, instead of earning $100,000 themselves and having other people earn $200,000.
A similar effect is seen for possessions. When there are so many flat-screen HD TVs to choose from, it's easy to make unfavourable comparisons between our choice and the others available.An abstract sense in the passage refers to awareness of something __________.
| A．you cannot think about |
| B．you can’ t remember well |
| C．you cannot understand |
| D．you cannot see or touch |
If you make an experiential purchase before a material purchase, you may go to__________.
| A．a theatre before going to a store |
| B．an exhibition before going to a park |
| C．a mall before going to a grocer's |
| D．a market before going to a restaurant |
The example of earnings is given to actually indicate__________.
| A．how ridiculous people are | B．how people feel content |
| C．how nearsighted people are | D．how people hold prejudice |
It is implied in the passage that, after their material purchases, people might__________.
| A．enjoy their ownership of what they have bought |
| B．pick every fault in the products they have got |
| C．regret making a wrong decision to buy the items |
| D．leave what they’ve purchased untouched at home |
Severely disabled people may soon be able to use their noses to write, drive a wheelchair or surf the Internet, thanks to a device (装置) developed by doctors in Israel.
The device will be used by breathing in and out through the nose, according to a study. Healthy people who tested the device quickly learned to play computer games and write sentences by sniffing. Encouraged by the results, the researchers decided to test their device on people who are paralyzed (瘫痪) but whose intelligence remains normal. Ten paralyzed who tested the device quickly learned to use their noses to write words, open a webpage, copy words and put them into a search engine.
With their success in helping severely disabled people to communicate * the researchers decided to make use of the new technology to design an electric wheelchair to be driven by sniffs.
Ten healthy people easily mastered sniff—driving a wheelchair through a maze (迷宫), and a 30-year-old man who had been paralyzed from the neck down for six years was as good a sniff-driver as the healthy participants at his second attempt. In other words, a paralyzed person could use the sniff controller to drive an electric wheelchair.
At the moment, sniff-controlled technology is still in the stage of development, and the Weizmann Institute has already applied for a patent on the device. "Ill be very happy if it can help us to make money, but the real problem is that I hope someone will develop it, because this would help a lot of people," said Sobel, one of the lead researchers of the study. What’s the purpose of the passage?
| A．To introduce a new invention. |
| B．To equip the disabled with life skills. |
| C．To show the nose's special functions. |
| D．To instruct doctors to apply for a patent. |
In the test, the paralyzed people with normal intelligence can use their nose to ______.
| A．type long sentences quickly |
| B．play computer games easily |
| C．enter a website without much difficulty |
| D．communicate with others successfully |
With the help of the sniffing device, a 30-year-old disabled man ______.
| A．spent six years learning how to drive a wheelchair |
| B．failed to drive through the maze at his first attempt |
| C．took the wheelchair controlled by healthy participants |
| D．managed to drive an electric wheelchair by sniffing |
From the last paragraph, we can infer that the sniff-controlled technology ______.
| A．will be applied to other fields of research |
| B．needs further developing to serve more people |
| C．has become an important patented invention |
| D．shows the wisdom and talents of Israel doctors |
