Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. "We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is COx levels. And We've been able to record this increasing quantity of atmospheric CO, into the ocean. "Scientists expected that as atmospheric CO2 increased, more and一 more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater samples Dow and his colleagues have analyzed confirm what the theory predicts. The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic."

Today just as technology changed the face of industry, farms have undergone an “agricultural revolution”. On the farm of today, machines provide almost all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.
【小題1】According to the passage, computers can NOT help farmers decide _______.
| A．what livestock to raise |
| B．whether to plant a certain kind of crop |
| C．how much money they can earn from their products |
| D．when to sell their products |
| A．Farmers in the future will depend totally on computers. |
| B．Both computers and robots have been in use on today’s farms. |
| C．Farmers mainly use machines on their farms at present. |
| D．Students at agricultural colleges must take computer classes because they can do nothing without the help of computers on today’s farms. |
| A．a(chǎn)ll farm work | B．milking cows |
| C．most of the farm work | D．some farm work |
| A．Computer, Farmers’ Best Friend |
| B．The Agricultural Revolution |
| C．Farmers in The Future |
| D．Computers and Robots |

Mass transportation revised the social and economic fabric of the American city in three fundamental ways. It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life. By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant form city centers than they were in the premodern era. In 1850, for example, the borders of Boston lay scarcely two miles from the old business district; by the turn of the century the radius extended ten miles. Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment. The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and fueled what we now know as urban sprawl. Between 1890 and 1920, for example, some 250,000 new residential lots were recorded within the borders of Chicago, most of them located in outlying areas. Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area. Anxious to take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years – lots that could have housed five to six million people.
Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities. These excesses underscore a feature of residential expansion related to the growth of mass transportation: urban sprawl was essentially unplanned. It was carried out by thousands of small investors who paid little heed to coordinated land use or to future land users. Those who purchased and prepared land for residential purposes, particularly land near or outside city borders where transit lines and middle-class inhabitants were anticipated, did so to create demand as much as to respond to it. Chicago is a prime example of this process. Real estate subdivision there proceeded much faster than population growth.

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the dolts.
The aggregate scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their home.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.
【小題1】The purpose of the passage is to tell us that ________.
| A．man are smarter then women |
| B．man are more stupid the women |
| C．a(chǎn) new fact about the IQ of men and women has been found |
| D．men are more likely to receive first class university degrees |
| A．they are born stupid |

| C．women are securing more firsts and seconds |
| D．women are doing much better in academy |
| A．Why are men smarter than women? |
| B．Why are men more stupid than women? |

LONDON—Here’s a new warning from health experts：Sitting is deadly.
Scientists are increasingly warning that sitting for long periods—even if you also exercise regularly—could be bad for your health.And it doesn’t matter where the sitting takes place—at the office，at school，in the car or before a computer or TV—just the overall number of hours it occurs.Several studies suggest people who spend most of their days sitting are more likely to be fat，have a heart attack or even die.
In an editorial published this week in the British Journal of Sports Medicine，Elin EkblomBak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.
While health officials have issued guidelines recommending minimum amounts of physical activity，they haven’t suggested people try to limit how much time they spend in a seated position.
“After four hours of sitting，the body starts to send harmful signals，”said EkblomBak.She explained that genes regulating(調(diào)節(jié)) the amount of glucose(葡萄糖) and fat in the body start to shut down.
Even for people who exercise，spending long periods of time sitting at a desk is still harmful.Tim Armstrong，a physical activity expert at the World Health Organization，said people who exercise every day—but still spend a lot of time sitting—might get more benefit if that exercise was spread across the day，rather than in a single bout(一回)．
Still，in a study published in 2009 that tracked more than 17,000 Canadians for about a dozen years，researchers found people who sat more had a higher death risk，whether or not they exercised.
“We don’t have enough evidence yet to say how much sitting is bad，” said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge，who led the Canadian study.“But it seems the more you can get up and interrupt this sedentary behavior，the better.”
Figures from a U．S. survey in 20032004 found Americans spend more than half their time sitting，from working at their desks to sitting in cars.
Experts said more research is needed to figure out just how much sitting is dangerous，and what might be possible to offset those effects.
“People should keep exercising because that has a lot of benefits，” EkblomBak said.“But when they’re in the office，they should try to interrupt sitting as often as possible，” she said.
【小題1】What is the best title for the text?
| A．Not Sitting Too Much While Working |
| B．How to Avoid Sitting Too Much |
| C．Sitting Too Much Could Be Deadly |
| D．More and More People Sit Too Much |
| A．the more time you spend in exercising in a single bout(一回)，the healthier you will be |
| B．those who often sit too much are sure to grow fat or suffer from a heart attack |
| C．regular exercise is effective to get rid of the side effects of sitting too much |
| D．you had better not sit for more than four hours in a single bout |
| A．It results in a higher death risk. |
| B．It increases glucose and fat in the body. |

When author Nicholas Carr began researching his book on whether the Internet is ruining our minds，he restricted his online access and email.His new book argues the latest technology renders us less capable of deep thinking.Carr found himself so distracted(分心的) that he couldn’t work on the book while staying as connected.After first feeling confused by his sudden lack of online connection，he was able to stay focused on one task for a long period within several weeks.
Reading on the Internet has changed how we use our brains.Facing a lot of texts，video，music and links to other web pages and blogs，our minds have become used to skimming and scanning information.As a result，we have developed sharper skills at making fast decisions，particularly visual ones，Carr wrote.
But now most of us seldom read books or long articles that would help us focus.We are becoming more like librarians—able to find information quickly and see clearly the best nuggets(有價值的資料)．That lack of focus hinders(阻礙) our longterm memory，leading many of us to feel distracted，he wrote.
“What we are losing is a whole other set of mental skills，which require not the shifting of our focus but the maintaining of our focus，” Carr said，adding that for centuries books protected our brains from distraction and focused our minds on one topic at a time.
But with devices such as Apple’s iPad becoming common，Carr predicts books also will change.“New forms of reading always require new forms of writing，” he said.Carr has a suggestion for those who feel web surfing has left them incapable of concentration—slow down，turn off the Internet and practice the skills of contemplation(沉思) and reflection.“It is pretty clear from the brain science that if you don’t exercise particular cognitive skills，you are going to lose them，” he said.“If you are constantly distracted，you are not going to think in the same way that you would think if you paid attention.”
【小題1】What topic is Nicholas Carr’s new book mainly concentrating on?
| A．Whether there is any need for us to surf the Internet. |
| B．How the Internet changes our way of thinking. |
| C．What we should do when we are surfing the Internet. |
| D．Whether our minds are being influenced by the Internet. |
| A．Anxious. | B．Relaxed. |
| C．Concentrated. | D．Puzzled. |
| A．prevents | B．causes |
| C．protects | D．sharpens |
| A．They should read more books besides surfing the Internet. |
| B．They should often slow down their pace of modern living. |
| C．They should often get away from the disturbing of the Internet. |
| D．They should spend more time thinking while surfing the Internet. |

Inside their one-store, metal-roofed house on Vancouver Island’s west coast，Janet Schwartz and her domesticated(馴養(yǎng)的) deer, Bimbo, are returning to their normal lives. The law-represented by men and women dressed in black uniforms and carrying guns — is no longer threatening to forcibly separate Schwartz and Bimbo，freeing the l0-year-old deer to the fates (命運) of the surrounding rainforest and its hungry wolves and black bears．
“We love each other，”said Schwartz who turned 70 on Saturday. “she’ll come up to me and she’ll kiss me right on the lips，like a man kisses a woman’’
For four days last week，Schwartz’ life turned as rocky as the rough logging road that connected her life to the outside world. Conservation officers had arrived with orders to loose Bimbo. Schwartz was told she wasn’t allowed to touch Bimbo any more. It seemed somebody had complained，said Environment Minister Terry Lake earlier in the week, noting it’s illegal to keep wild animals as pets.
During those tense days，sleepless nights were made even more restless by nightmares，said Schwartz. There were news stories and Facebook pages which supported Schwartz and by Friday，the government had changed its mind. Schwartz could keep her pet with the help of a veterinarian and conservation officers.
“It makes me feel good，”said Schwartz of the announcement．“She is my life．a(chǎn)nd I’ve had her since the day she’s been born.”
The relationship began when a friend found the orphaned fawn (幼鹿) along a nearby logging road，more than a kilometer away from her current home，said Schwartz. The friend brought the fawn over because she knew Schwartz had raised a deer before.
Schwartz named the fawn(小鹿) Bimbo，based on a Gene Autry song that was playing inside her home at the time，and began feeding the animal goat’s milk. Days turned into months and years, and now Bimbo is a part of the family.
【小題1】According to Paragraph 1 , Janet Schwartz’s life is returning to normal because
| A．no one disturbs her life again | B．she can continue to keep the deer |
| C．she has married again | D．Bimbo has returned to the forest |
| A．It was the only companion in her house |
| B．She wanted to study the lifestyle of the deer． |
| C．The deer had become part of her life． |
| D．She had a veterinarian to help her． |
| A．the deer was not properly taken care of |
| B．the deer brought harm to the neighborhood |
| C．it was against the law to keep the deer as a pet |
| D．the deer made too much noise |
| A．Schwartz’s love for the deer. |
| B．The threat to the deer in the wild. |
| C．The change of the law. |
| D．The influence from the press and the Web. |

The art of reading fiction is largely a matter of inferring meanings. To infer means to understand facts which are not directly stated---only suggested. Inference is one of the commonest ways of knowing things: a child holds his knee and cries; this action implies his feeling; an observer infers that the child is hurt. To infer accurately in everyday life requires caution in observing; to infer skillfully in fiction requires caution in reading; both require disciplined imagination.
The short-story reader can expect to find certain basic elements in any story. For example, all stories involve a person or persons, in a particular setting, faced with a demand for a response. The response called for may be a physical action, such as defeating an adversary(對手) or escaping from a danger; or it may be a mental action, such as adjusting to others or within oneself. In either case, the short story is a description in two ways: first, it shows the motives for a given human action; second, it makes a point about the general human situation. Such descriptions, however, rather than being stated directly, usually are implied by the elements of the story.
When the reader of a story understands all the facts and their interrelationships, he is ready to infer the significance of the story as a whole---its comment on the human situation. This comment, or theme, is the seed from which the story grew. It is also the idea by which all the separate elements of the story are governed, while these in turn further shape and modify the theme. In addition to action, character, and setting, these elements include structure, mood, tone, and point of view.
Fiction reading requires an awareness of all the ways in which a story communicates. It also requires attention to detail. What the author provides is a network of points which serve as clues to his meaning. He invites the reader to develop the meaning by inference, actually to create much of the story himself and so make it part of his own experience.
【小題1】According to the author, "infer" means ________ .
| A．knowingfactsbeyondthestatement |
| B．lookingformoreevidencesforthestatement |
| C．findingoutadifferentmeaningfromthestatement |

The weather predictions for Asia in 2050 read like a story from a doomsday movie.
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring. In the decades to come, Asia---home to more than half the world’s 63 billion people-will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels.
“It’s not a pretty picture,” said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse is likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters. According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate(疏散) or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes with rising populations and demand for food, water and other resources. Experts say environmental worsening such as deforestation and pollution will probably enlarge the results of climate change.
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill.
The year before, a winter cold struck and a summer heat wave killed more than 2,000 people in India.
【小題1】This passage is mainly about .
| A．what kind of weather we like best |
| B．the weather predictions for Asia in the future and the reasons |
| C．how to improve our environment |
| D．that the world will not be suitable for us to live in |
