A board game is a game played on a pre-marked surface or “board” according to a set of rules. Board games have been played in most cultures and societies throughout history. Do you think of yourself as a bit of an expert at board games like chess or Go?
Maybe you’re not quite as good as you think. New research from the University of Manchester and Oxford suggests complex games like these are impossible to learn fully. They may even be too complex for the human mind to understand.
Researchers studied two-player games, to try and understand the strategies which people use to make decisions during the game. Some games with two players are simple, with only a small number of possible moves. Players can quickly work out the best strategy but that means the game soon becomes boring.
It gets more interesting when there are many possible moves. That’s why people are so fascinated by complex board games like chess or Go, or some card games. But what the researchers found was that with difficult games, players find it hard to work out the best strategy and their actions become less reasonable.
This research is part of the field called game theory: the study of human strategic decision-making. Much thinking on how people play complex games is based on something called “the balance point”, which is when players have a perfect knowledge of what they are going to do and of what their rivals are going to do.
When you add more than two players then of course the game becomes even harder to understand. Trading on the stock market is an example of a complex multi-player game.

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” |

A smart phone (智能手機(jī)) is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation (導(dǎo)航) units to form one multi-use device. Many modem smart phones also include touch screens and web browsers (瀏覽器) that display web pages.
A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn’t mean making calls, but playing phone games and browsing the Web.
Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It’s no secret that our lives are being affected by our smart phones obsession.
However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen.
Ironically, YouTube’s data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones.
The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it.
【小題1】People prefer a smart phone to a common one, because the latter only can help us ______.
A.check emails | B.send messages | C.find the destination | D.watch a video |
A.devotion | B.contribution | C.a(chǎn)ddiction | D.emotion |
A.People spend as average of two hours and 40 minutes each day using smart phones. |
B.The film hasn’t been put on in the cinema. |
C.The film is written by an actor named Charlene Deguzman. |
D.The film has already been viewed more than 105 million times in the first few days. |
A.encouraged | B.depressed | C.proud | D.satisfied |

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 |

The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蟻堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通風(fēng)口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned buildings, where up to 30% of the air is recycled.
【小題1】Why was Eastgate cheaper to be built than a conventional building?
A.It was designed in a smaller size. |
B.No air conditioners were fixed in. |
C.Its heating system was less advanced. |
D.It used rather different building materials. |
A.Fresh air from outside. | B.Heat in the building. |
C.Hollow space. | D.Baseboard vent. |
A.New York has less clear skies as Harare. |
B.Its dampness affects the circulation of air. |
C.New York covers a larger area than Harare. |
D.Its temperature changes seasonally rather than daily. |
A.a(chǎn)llows a wide range of temperatures |
B.functions well for most of the year |
C.can recycle up to 30% of the air |
D.works better in hot seasons |

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
【小題1】The biggest difficulty in operating on the damaged brain is that _______.
A.the time is too short for doctors |
B.the patients are often too nervous |
C.the damage is extremely hard to fix |
D.the blood-cooling machine might break down |
A.taking the blood out of the brain |
B.trying the operation on monkeys first |
C.having the blood go through a machine |
D.lowering the brain' s temperature |
A.can last as long as 30 minutes |
B.can keep the brain' s blood warm |
C.can keep the patient' s brain healthy |

Businesses are witnessing a difficult time,which has in turn produced influence on consumers’ desire to go green.However,shoppers are still laying stress on environmental concerns.
Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago,while more than a quarter say that they are now even better aware of the environmental effect on what they buy.
This may help to influence how shops store goods on their shelves.And the companies should still make efforts to become more environmentally friendly.Two out of three people think it is important to buy from environmentally responsible companies,with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company’s environmental reputation was not good enough.
Harry Morrison,chief executive(主管)of the Carbon Trust,sympathizes:“I understand this situation where survival is very important now.But from environmental considerations,the clock is ticking—we don’t have much time.In addition,cutting carbon has an immediate effect as costs drop and a mediumterm benefit for the brand.”
Larger companies have an extra motivation to look at reducing their carbon footprint,as new rules next year will require businesses to buy carbon allowances to make up for their emissions(排放).Those that have taken early action will have a head start.More than two thirds of consumers are not clear about which companies are environmentally responsible.This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers.
The Carbon Trust believes that it can help by informing customers about the good work companies are doing.“When companies are granted(授予) the standard,they can use a logo(標(biāo)識(shí)) in all their marketing which makes it clear that they are working towards cutting emissions,” Mr.Morrison said. (2010·福建,C)
【小題1】What’s the main idea of the passage?
A.Businesses are finding ways to send their message to the shoppers. |
B.Companies will soon get information about cutting carbon emissions. |
C.Firms are making efforts to encourage customers to keep goods at home. |
D.Firms are urged to cut carbon emissions by shoppers’ environmental awareness. |
A.a(chǎn)ffect | B.change | C.disturb | D.reject |
A.will benefit from cutting carbon emissions |

Fish species are expected to shrink in size by up to 24% because of global warming, say scientists.
The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected.
The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size.
The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future."
Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans.
When compared with actual observations of fish sizes, the model seems to underestimate what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted.
Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously affect the ability of fish to reproduce. "Smaller fish produce fewer and smaller eggs which could affect the reproductive potential of fish stocks," he said.
【小題1】What's the main idea of the passage?
A.Global warming makes fish smaller. |
B.Global warming makes fish decrease in numbers. |
C.Global warming affects the fish distribution. |
D.Global warming affects the ability of fish to reproduce. |
A.The rising body temperatures. |
B.The lower level of oxygen in the water. |
C.The increasing metabolic rate. |
D.The normal body activities. |
A.more big fish will be born in the sea |
B.fish tend to swim towards the shore |
C.fish tend to move towards the warm areas |
