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.

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.
Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牽牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meateating plants，” they added.
【小題1】Tomatoes and potatoes kill insects to ________.
| A．get more sticky hairs |
| B．make themselves grow better |
| C．make their roots stronger |
| D．a(chǎn)void falling down to the ground |

If you think English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the earlier people learn a second language, the greater the effect is.
A team led by Dr. Andrea Mechelli, from University College London(UCL), took a group of Britons who only spoke English. They were compared with a group of“early bilinguals(通兩種語言的人)”, who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference was.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,”said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills.
“Having two languages gives you two windows on the world and makes the brain more flexible,”he said,“You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing and comprehension were all tested. The results showed that the earlier they started to learn, the better.“Studying a language means you get an entrance to another world,”explained the scientists.
【小題1】What does the underlined part“grey matter”(in paragraph 2) refer to?
| A．Grey hair. | B．Material of the brain. |
| C．Intelligence. | D．Difficult situations. |
| A．change one’s brain completely |
| B．improve one’s maths skills |
| C．make one smarter than others |
| D．increase the ability to learn |
| A．the researchers from UCL did another study in Italy |
| B．a(chǎn) similar study was done on native Italian speakers who learn English as a second language |
| C．the research done on the Italians showed a totally different result |
| D．it will be easier for one to travel around the world by learning a second language |
| A．Learning a second language can help improve your brain power. |
| B．You should learn a second language in English that is not your native language. |
| C．If you want to learn a second language, you should do it at a certain age. |
| D．The research done by the researchers from UCL is very successful. |

Can noncombustion (非燃燒) technology create a no-pollution way to drive？Imagine pulling into a service station to fuel up your car. But not at the gas pump or electric battery charger —at the air pump! That’s not hot air, either! The next generation of cars may run on thin air. Wouldn’t that be an incredible way to cut both pollution and dependence on foreign oil?
If you’ve ever inflated a balloon and then let it go, you’ve got the basics to test-drive the amazing MiniCAT, currently being developed by Noteur Development International (MDI), headquartered in Luxembourg. Invented by Formula One racing car designer Guy Negre, this experimental vehicle is unlike any car you’ve ever seen. While your family’s traditional car or SUV draws its horsepower using combustion, the only fuel that MiniCAT needs (CAT stands for Compressed Air Technology) is the air we breathe.
Start with about 25,000 gallons of air. Now, press it all into a space smaller than your school locker—because that’s the size of two super-strong, high-pressure air tanks, made from fiber and fixed beneath the air car.
Confining that much air inside those small tanks generates an internal pressure of over 4,000 pounds per square inch. That’s over 300 times normal air pressure.
When this cold, high-pressure air enters MiniCAT’s unique engine, it interacts(交互作用) with warmer air to create pressure waves that pump the engine’s engineered pistons (活塞) to move the car. MiniCAT’s projected top speed is 60 miles per hour, with a range of 120 miles on a full air supply.
【小題1】What is the passage mainly about?
| A．Ways to cut down air pollution. |
| B．Cars that run on thin air. |
| C．Formula One racing car designer. |
| D．Dependence on foreign oil. |
| A．The name of a car. |
| B．The name of a balloon. |
| C．The name of a car company. |
| D．The name of a car designer. |
| A．Keeping | B．Preventing | C．Pushing | D．Running |
| A．How much pressure the air creates. |
| B．How the car works. |
| C．What the normal air pressure is. |
| D．How the air gets into the engine. |

Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.
Butterflies have large compound eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to honey sources.
Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae, feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.
Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Butterflies don't have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations.
Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.
【小題1】The text mainly focuses on ________.
| A．butterflies' living habits | B．butterflies' beauty |
| C．butterflies' senses | D．butterflies' daily activities |
| A．Butterflies can see in all directions and don't need to turn heads. |
| B．Butterflies have good eyesight. |
| C．Butterflies are sensitive to bright colors including red and yellow. |
| D．Butterflies cannot sense the ultraviolet light. |
| A．To find highqualified honey. |
| B．To have a good place for living. |
| C．To make it easier for them to hide from the enemies. |
| D．To find a proper place for their eggs. |

Some weightloss camps, which are rare in China just a few years ago，have multiplied in Beijing, Qingdao, Shenzhen，and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight.Of these, 90 million—about 7 percent—are obese(極肥胖的)．
Experts say the obesity epidemic(流行病) is spreading to children, though more slowly than in adults. The obesity, they say, will do harm to the health of China’ s citizens and economy.“We're seeing a very large number of teenagers who are quite heavy and aren't moving much，” said Barry Popkin, a nutrition(營養(yǎng)) professor. Popkin carries out an ongoing healthandnutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight “quite quickly.” In just ten years China‘s childhood obesity rate has doubled，with the greatest gains coming in urban areas.“In big cities it's a big problem.”
Some experts blame the extra fat on a range of factors, many of them tied to China’ s rapidly changing economy and culture. The diets of Chinese adults and children are far higher in meats, fish, eggs, dairy products, fats and sugars than ever before. In addition，kids—especially city dwellers—are more sedentary today and spend more time indoors in front of homework, television，computer games, and the Internet.
Shuwen Ng，a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features.
China’ s childhood obesity rate stillfall behind that of the United States, where some 15 percent of kids are said to be obese. But the longterm effects are equally serious.
【小題1】According to the passage we know________.
| A．weightloss camps have been very popular in China six years ago |
| B．a(chǎn)bout 290 million Chinese are overweight in China in all |
| C．in China childhood obesity rate in rural areas is lower than that in major cities |
| D．America’ s childhood obesity rate is lower than China’s |
| A．Advertising on some new candies. |
| B．ignorance of weight-control. |
| C．Playing computer games for long time. |

Where do you find out about the world’s longest walk? The world's tallest man? The world's oldest woman? You know the answer, of course. It is the Guinness Book of World Records. How would people find such unusual facts without this book?
Guinness Book did not exist until 1951. Here is what happened. The managing director of Guinness Brewery was a curious man. He wanted answers to some questions about records. For example, he wanted to know what was the fastest flying game bird in Europe. But he was frustrated. There was no book to answer questions like this.
The director, Sir Hugh Beaver, contacted the McWhirter twins. They were brothers who owned a research agency. He asked them to put together a new reference book. It would include all kinds of unusual records. The brothers quickly accepted. The first edition of their book was published in 1955. Soon the Guinness Book of World Records was a best seller. It has sold more copies than any book except the Bible. A new edition is published every year.
Where do all the book's records come from? They are a combination of things like natural wonders, sports records, and stunts(特技) (How many people would push an egg with their noses if they weren’t trying to get to the book?). But the editors try to keep things honest. All records must be verified by an investigator. Only then are they printed.
The Guinness Book is a big business. It is published in dozens of languages. There are TV shows and museums. It is proof of how interested people are in strange pieces of information.
【小題1】The passage is mostly about _____.
| A．the McWhirter twins |
| B．the director Sir Hugh Beaver |
| C．unusual records in the Guinness Book |
| D．a(chǎn) history of the Guinness Book |

“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多種維生素make you healthier?
“We believe that the case is closed - supplementing(補(bǔ)充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(認(rèn)知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰劑)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.
【小題1】This text is likely to be selected from a book of .
| A．medicine | B．education | C．food | D．business |
| A．Vitamins should not be used for chronic disease prevention. Enough is enough. |
| B．Having a balanced diet and exercising would probably be a better way to keep healthy. |
| C．The three studies do not provide support for use of multivitamin supplements. |
| D．Taking vitamins to replace or supplement your healthy diet is necessary. |
| A．Vitamin supplements have proved harmful to the health of adults. |
| B．Vitamin supplements are beneficial in certain conditions. |

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."
【小題1】What can be the best title of the passage?
| A．Sea Life Facing Danger | B．Scientist Researching Seawater |
| C．Oceans Becoming More Acidic | D．Climate Change Affecting Seawater |
| A．more corals will appear in the sea |
| B．the surface water is becoming warmer |
| C．the chemical balance of the seawater is affected |
| D．the pH of the ocean out here has been increasing |
| A．a(chǎn)bcde | B．dbcea | C．a(chǎn)ebed | D．edcba |
