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.

Last summer, two nineteenth-century cottages were rescued from remote farm fields in Montana, to be moved to an Art Deco building in San Francisco. The houses were made of wood. These cottages once housed early settlers as they worked the dry Montana soil; now they hold Twitter engineers.
The cottages could be an example of the industry’ s odd love affair with “l(fā)ow technology,” a concept associated with the natural world, and with old-school craftsmanship (手藝) that exists long before the Internet era. Low technology is not virtual (虛擬的) —so, to take advantage of it, Internet companies have had to get creative. The rescued wood cottages, fitted by hand in the late eighteen-hundreds, are an obvious example, but Twitter’s designs lie on the extreme end. Other companies are using a broader interpretation (闡釋) of low technology that focuses on nature.
Amazon is building three glass spheres filled with trees, so that employees can “work and socialize in a more natural, park-like setting.” At Google’s office, an entire floor is carpeted in glass. Facebook’s second Menlo Park campus will have a rooftop park with a walking trail.
Olle Lundberg, the founder of Lundberg Design, has worked with many tech companies over the years. “We have lost the connection to the maker in our lives, and our tech engineers are the ones who feel impoverished (貧乏的) , because they’re surrounded by the digital world,” he says. “They’re looking for a way to regain their individual identity, and we’ve found that introducing real crafts is one way to do that.”
This craft based theory is rooted in history, William Morris, the English artist and writer, turned back to pre-industrial arts in the eighteen-sixties, just after the Industrial Revolution. The Arts and Crafts movement defined itself against machines. “Without creative human occupation, people became disconnected from life,” Morris said.
Research has shown that natural environments can restore(恢復(fù)) our mental capacities. In Japan, patients are encouraged to “forest-bathe,” taking walks through woods to lower their blood pressure.
These health benefits apply to the workplace as well. Rachel Kaplvin, a professor of environmental psychology, has spent years researching the restorative effects of natural environment. Her research found that workers with access to nature at the office—even simple views of trees and flowers—felt their jobs were less stressful and more satisfying. If low-tech offices can potentially nourish the brains and improve the mental health of employees then, fine, bring on the cottages.
【小題1】The writer mentions the two nineteenth-century cottages to show that ________.
A.Twitter is having a hard time |
B.old cottages are in need of protection |
C.early settlers once suffered from a dry climate in Montana |
D.Internet companies have rediscovered the benefits of low technology |
A.is related to nature | B.is out of date today |
C.consumes too much energy | D.exists in the virtual world |
A.have destroyed many pre-industrial arts |
B.have a tradition of valuing arts and crafts |
C.can become intelligent by learning history |
D.can regain their individual identity by using machines |
A.positive | B.defensive | C.cautious | D.doubtful |
A.Past Glories, Future Dreams |
B.The Virtual World, the Real Challenge |
C.High-tech Companies, Low-tech Offices |
D.The More Craftsmanship, the Less Creativity |

Have you seen a yellow-and-black salamander (火蜥蜴)? How about a scarlet frog? Scientists haven’t spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct?
Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.
The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.
Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.
“If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.
“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”
Lost in the Wild
Scientists’ hunt for missing amphibians is under way. Read about some of the species they hope to find.
Turkestanian salamander
This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since.
Gastric brooding frog
Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss.
Rio Pescado stubfoot toad
Last sighting: 1995, in South America
Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
【小題1】 Which of the following animals hasn’t been seen for over a century?
A.Rio Pescado stubfoot toad. |
B.Gastric brooding frog. |
C.Turkestanian salamander. |
D.Scarlet frog. |
A.the scarlet frog used to live in Africa |
B.researchers have no way to save amphibians |
C.the scientists will search 14 countries at most |
D.Robin Moore has begun his search for amphibians |
A.Because they want to rescue the missing amphibians. |
B.Because they want to set up a scientific program. |
C.Because they want to do a scientific research on the missing amphibians. |
D.Because they want to publish a report about the missing amphibians on WR News. |
A.It’s hopeful. | B.It’s interesting. |

One night in March 1999, a man was driving from California to Oregon, US, to visit some friends. He had stopped his car to have some food when he started to hear strange noises. Turning on the headlights, he saw an 8-foot-tall creature covered in thick, dark hair. The creature stared at him for a minute, turned in the road and walked off slowly into the woods.
In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜馬拉雅山地區(qū))and even Hubei Province in China. The creature is known as bigfoot.
Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(類人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.
Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet’s undiscovered secrets. There is a little evidence(證據(jù))to support the believers’ theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.
But so far, no one has found bones or any other definite proof that the giant creature exists.
As a result many people believe the evidence is just part of a big trick.
The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.
They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.
【小題1】 So far what we can be sure about is that .
A.there exist savages(野人)in several places in the world |
B.there are some traces of hair, footprints and body prints of the “bigfoot” |
C.bigfoot is a direct descendent of ancient gigantopithecus |
D.a(chǎn)ll the big foot discovered have the same look |
A.1999 | B.the 1960’s |
C.the 1950’s | D.the 1940’s |
A.may fool the world into believing |
B.have definite evidences to prove |
C.refuse to believe |
D.will soon offer proofs of |
A.a(chǎn)pes |
B.bears |
C.gigantopithecus |

The biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference (電磁干擾). The source of this interference remains not proved, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.
RTC.A. an organization which advises the aviation (航空 )industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take- off and landing. Some experts have gone further, calling for a total ban during all flights .Cur- rently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are un- willing to carry out a total ban, given that many passengers want to work during flight.
The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory. they have no way of knowing whether the interference might be. dangerous or not.
The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud.
【小題1】What is said about the over 100 aircraft incidents in the past 16 years?
A.They may have been caused by the damage to-the radio systems. |
B.They may have taken place during take-off and landing. |
C.They were proved to have been caused by the passengers portable computers. |
D.They were suspected to have resulted from electromagnetic interference. |
A.Because it is extremely dangerous to conduct such research on an airplane. |
B.Because it remains a mystery what wavelengths are liable to be interfered with. |
C.Because research scientists have not been able to produce the same effects in labs. |
D.Because experts lack adequate equipment to do such research. |
A.they don't believe there is such a danger as radio interference |
B.the harmful effect of electromagnetic interference is yet to be proved |
C.most passengers refused to take a plane ,which bans the use of radio and cassette players |
D.they have other effective safety measures to fall back on |
A.a(chǎn) new rule for all airlines |
B.the disadvantages of electronic devices |
C.a(chǎn) possible cause of aircraft incidents |
D.effective safety measures for air flight |

IT’S never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter – people have many different ways of coping with the cold.
But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat to keep themselves warm. So how do they manage to survive the freezing winter?
It turns out that plants have their own strategies too, said a study published on Dec 22 in the journal Nature.
According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite (凍瘡),” Zanne told Science Daily. Also, the process of freezing and thawing (解凍) can cause air bubbles to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
To live through cold weather, plants have developed three traits, according to the study. Some plants, such as oak trees, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
Other plants, pine trees for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
However, the study also found that these smart strategies were developed very slowly – over millions of years of evolution. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
Scientists are hoping that this study can help people find possible ways to save plants from the threat of climate change.
【小題1】What is the article mainly about?
A.Why plants are not afraid of the winter chill. |
B.The ways that plants survive cold weather. |
C.Changes in plants’ water transport system in winter. |
D.How plants evolve to keep up with climate change. |
A.it produces more living tissues to stay alive |
B.its leaves quickly fall out and its roots begin to die |
C.lots of air bubbles form in its water transport system |
D.its water transport system could be blocked in the spring |
A.By dropping their leaves before winter. |
B.By narrowing their water transport cells. |
C.By widening their water transport cells. |
D.By leaving only the seeds alive and growing from the seeds in the spring. |
A.Plants may not be able to adapt to the increasingly cold climate. |
B.Human activities might have a great impact on the pace of plants’ evolution. |
C.Plants may not be able to evolve fast enough to adapt to human-caused climate change. |
D.The strategies plants develop are not good enough to protect them against cold. |

Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day.
We realized a long, long time ago that nature provides the best blueprint for invention. We’ve borrowed canals from beavers and reflectors from cat’s eyes. Although the words “bionics”(仿生學(xué)) became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(檔案) don’t go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.
To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright’s pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter .
Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic(簡單抽象藝術(shù)) structure. On the other hand, Barney Connett’s fish submarine actually looks like a fish.
Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(螞蚱)-sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.
【小題1】“Cats”, “monkeys” and “giraffes” mentioned in paragraph 1 are examples to show______.
A.they are highly-evolved species as humans |
B.a(chǎn)nimals have skills that humans do not possess |
C.humans can learn animals’ skills |
D.they are skillful in different ways |
A.People carried out a systematic study on pigeons. |
B.People studied more animals and plants to develop the airplane. |
C.People could fly their airplane for fun. |
D.People kept their airplane at a French gallery. |
A.It has cost a large sum of money. |
B.It has changed our life. |
C.It has improved the abilities of tanks |
D.It has not succeeded yet. |
A.many inventions get ideas from nature. |
B.Some animals possess unique skills. |
C.People should protect nature. |
D.Bionics is far from perfect |

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 |

科目:高中英語 來源: 題型:閱讀理解
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.

[A] To demonstrate positive and negative effects of growth.
[B] To exemplify cities with and without mass transportation.
[C] To show mass transportation changed many cities.
[D] To contrast their rate of growth.
【小題3】According to the passage, what was one disadvantage of residential expansion?
[A] It was expensive.
[B] It happened too slowly.
[C] It was unplanned.
[D] It created a demand for public transportation.
【小題4】The author mentions Chicago in the second paragraph as an example of a city,
[A] that is large.
[B] that is used as a model for land development.
[C] where the development of land exceeded population growth.
[D] with an excellent mass transportation system.
