Growers around the world are using new methods to grow grapes to make wine. They use natural and organic methods to control harmful insects and weeds instead of using chemicals. Now, a winery in Canada has adopted a natural way to control its grapevines (葡萄藤). The Featherstone Winery is in southern Ontario. The grapevines, like other plants, need to be cut every year.
Cutting grapevines must be done very carefully. Only a targeted area of leaves is removed from the lower part of the vines to help the grapes grow better. But at the Featherstone Winery, no man or machine does the cutting. Instead, the job is done by 40 little wooly lambs.
David Johnson owns the vineyard (葡萄園). He says he learned about using lambs while visiting wineries in New Zealand. The young lambs are perfectly designed to do the job. They eat the grape leaves on the lower parts of the vine. But they are not tall enough to reach the grapes. They only weigh about 22 kilograms, so they do not beat down the soil. And their waste makes good organic fertilizer. In addition, using the lambs costs much less than hiring workers to cut the vines for seven weeks in summer. And when the cutting is done in August, the lambs become tasty dishes.
Mr. Johnson says he had a difficult time finding enough lambs to do the job. There are about 50 million lambs in New Zealand. But there are not nearly as many in Ontario. Also, some organic pesticides (殺蟲(chóng)劑) are harmful to lambs. And the lambs must be watched to make sure they do not eat too much of the grapevines.
David Johnson says the lambs help him carry out his environmental ideas about farming. They are lovely and peaceful and he likes having them in his vineyard. People visiting the vineyard also enjoy watching the lambs do their job.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important, of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
【小題1】What does the underlined phrase "over-consumption" refer to?
A.Using too much packaging. |
B.Recycling too many wastes. |
C.Having more material than is needed. |
D.Making more products than necessary. |
A.the tendency of cutting household waste |
B.the increase of packaging recycling |
C.the fact of packaging overuse |
D.the rapid growth of supermarkets |
A.means burning packaging for energy |
B.helps control the greenhouse effect |
C.is the solution to gas shortage |
D.leads to a waste of land |
A.Unpackaged products are of bad quality. |
B.Supermarkets care more about packaging. |
C.Other products are better packaged than food. |
D.It is improper to judge quality by packaging. |
A.Needless material is mostly recycled. |
B.Fighting wastefulness is difficult. |
C.People like collecting recyclable wastes. |
D.The author is proud of their consumer culture. |

If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality(虛擬現(xiàn)實(shí))device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."
The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.
To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised(同步的)movement becomes comfortable, and participants really start to feel as though they are living in another person's body.
Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias(偏見(jiàn))that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.
The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."
【小題1】The word "swapping" (paragraph 1) is closest in meaning to______.
A.building | B.exchanging | C.controlling | D.transplanting |
A.our feelings are related to our bodily experience |
B.we can learn to take control of other people's bodies |
C.participants will live more passionately after the experiment |

What's going to happen in the future? Will robots take over our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen 10 to 30 years later from now, according to the BBC.
1.Digital money
We used to pay with cash for everything we bought. Now when we swipe(刷) our bus pass or use a credit card to shop online, money is spent without us even seeing it. In fact, we are already using one type of digital money.
You have to admit that using a card is much easier than searching your pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. People in Sweden completely stopped using cash last year, according to the Associated Press, and the US might be next.
2.Bionic(能力超人的)eye
It's no longer something only in a scifi movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data directly to the brain.
Although the bionic eye that's out now only allows patients to see lights and unclear shapes, a highresolution(高清晰度的) version could be just a few years away.
3.Selfdriving cars
Everything is going automatic these days—washing machines, ticket selling machines and even cars. Unlike a human driver, a selfdriving car won't get distracted by a phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself.
Many vehicle companies are now planning selfdriving cars. “By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road,” said Jeffrey Miller, professor at the University of Alaska Anchorage, US, in Wired magazine.
【小題1】The underlined word “distracted” in the article is closest in meaning to “________”.
A.directed | B.discouraged |
C.a(chǎn)ttacked | D.disturbed |
A.optimistic | B.pessimistic |
C.doubtful | D.cautious |
A.Learning Kit | B.Campus Trends |
C.Entertainment | D.Technology |

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 |

Scientists at Royal Holloway, University of London and Queen Mary, University of London have discovered that bees learn to fly the shortest possible route between flowers even if they discover the flowers in a different order. Bees are effectively solving the “traveling salesman problem”, and they are the first creatures found to do this.
The traveling salesman must find the shortest route that allows him to visit all locations on his route. Computers solve it by comparing the length of all possible routes and choosing the shortest, and it can keep computers busy for days. However, bees solve it without computer assistance using a brain the size of grass seed. Dr. Nigel Raine, from the School of Biological Sciences at Royal Holloway explains, “Bees solve traveling salesman problems every day. They visit flowers at multiple locations and because bees use lots of energy to fly, they find a route which keeps flying to a minimum. ”
The team used the computer to control artificial flowers to test whether bees would follow a route defined by the order in which they discovered the flowers or if they would find the shortest route. After exploring the location of the flowers, bees quickly learned to fly the shortest route.
As well as improving our understanding of how bees move around the landscape pollinating(授粉)crops and wild flowers, this research, which is due to be published in The American Naturalist, has other applications. Our lifestyle relies on networks such as traffic on the roads, information flow on the Web and business supply chains. By understanding how bees can solve their problems with such a tiny brain, we can improve our management of these everyday networks without needing lots of computer time. Dr. Raine adds, “Despite their tiny brains, bees are capable of extraordinary feats of behavior. We need to understand how they can solve the traveling salesman problem without a computer. ”
【小題1】 What would be the best title of the passage?
A.Bees help salesmen travel |
B.Tiny-brained bees solve a complex mathematical problem |
C.How bees discover the flowers |
D.How to solve the “traveling salesman problem” |
A.can be solved by a computer easily |
B.can’t even be solved by a computer |
C.can puzzle both people and computers |
D.remains to be solved by scientists |
A.provide further proof for the research |
B.tell us how bees can fly the shortest route between flowers |
C.tell us how the research about bees’ flying route was conducted |
D.explain the importance of the research |
A.a(chǎn)ll creatures are smarter than computers |
B.the research about bees’ flying route can be applied to many fields |
C.our networks are more complex than bees’ ones |
D.with the help of the computer we can find out how bees can solve the “traveling salesman problem” |

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(lèi)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 |

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. |

The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed”. But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?
Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.
The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing (引證) older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your friend who is slow to learn that he has the potential of an Einstein, you’re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays against funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.
In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem (自尊). The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”
Those with low self-esteem didn’t feel better after the forced self-affirmation (自我肯定). In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think of positive thoughts.
The paper provides support for newer forms of psychotherapy (心理治療) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (靜思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic viewpoint. Call it the power of negative thinking.
【小題1】The first paragraph is written _________.
A.to raise an argument about positive thinking |
B.to introduce the power of positive thinking |
C.to encourage people to have positive thoughts |
D.to introduce the $11 billion self-help industry |
A.positive thinking is not as powerful as negative thinking |
B.encouraging positive thinking may actually discourage people |
C.happy people can think positively while unhappy people can’t |
D.getting people to think positively can strengthen their confidence |
A.You are pointing out the mistakes he has made. |
B.You are reminding him that he is not intelligent. |
C.You are not taking his mistakes seriously enough. |
D.You are showing he has great potential in spite of faults. |
A.negative feelings must be got rid of |
B.there’s no point in thinking positively |
C.it doesn’t make sense to think negatively |
D.negative thinking is not always negative |
