Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it！”
But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮层) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代数) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.

Choosing the Right Resolution (决定)
Millions of Americans began 2014 with the same resolution they started 2013 with, a goal of losing weight. However, setting weight loss as a goal is a mistake.
To reach our goal of losing weight --- the output, we need to control what we eat --- the input ( 输入). That is, we tend to care about the output but not to control the input. This is a bad way to construce goals. The alternative is to focus your resolution on the input. Instead of resolving to lose weight, try an actionable resolution: “I’ll stop having desert for lunch,” or “I’ll walk every day for 20 minutes.” Creating a goal that focuses on a well-specified input will likely be more effective than concentrating on the outcome.
Recently a new science behind incentives (激励) , including in education, has been discussed. For example, researcher Roland Fryer wanted to see what works best in motivating children to do better in school. In some cases, he gave students incentives based on input, like reading certain books, while in others, the incentives were based on output, like results on exams. His main finding was that incentives increased achievement when based on input but had no effect on output. Fryer’s conclusion was that the intensives for inputs might be more effective because do not knoe how to do better on exam, aside from general rules like “study harder.” Reading certain books, on the other hand, is a well-set task over which they have much more control.
As long as you have direct control over your goal, you have a much higher chance of success. And it’s easier to start again if you fail, because you know exactly what you need to do.
If you want to cut down on your spending, a good goal would be making morning coffee at home instead of going to a cafe, for example. This is a well-specified action-based goal for which you can measure your success easily. Spending less money isn’t a goal because it’s too general. Similarly, if you want to spend more time with your family, don’t stop with this general wish. Think bout an actionable habit that you could adopt and stick to, like a family movie night every Wednesday.
In the long run, these new goals could become a habit.
【小题1】The writer thinks that setting weight loss as a goal is a mistake because _______ .
| A．it is hard to achieve for most Americans |
| B．it is focused too much on the result |
| C．it is dependent on too many things |
| D．it is based on actionable decisions |
| A．they obeyed all the general rules |
| B．they paid more attention to exams |
| C．they were motivated by their classmates |
| D．they were rewarded for reading some books |
| A．“I’ll give up desert.” |
| B．“I’ll study harder.” |
| C．“I’ll cut down my expense” |
| D．“I’ll spend more time with my family” |
| A．develop good habits and focus on the outcome |
| B．be optimistic about final goals and stick to them |
| C．pick specific actions that can be turned into good habits |
| D．set ambitious goals that can balance the input ang output |

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. ”
【小题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．all 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” |

The £109 Nest Protect Smoke Alarm promises Internet alerts（警报）and an end to the low battery chirp（短而尖的叫声）. Besides, it uses a voice to tell you where the fire is.
The alarm is the first UK product from Nest, which is run by iPod-inventor Tony Fadell. The company claims the device’s batteries will last for up to seven years. The device will offer a spoken warning before it sounds a major alarm. Also it will use text messages and apps on your phones to alert users to low-level risks.
The present smoke alarms constantly alert users to non-existent threats, which will make many users annoyed and finally remove their batteries altogether. “We’ve all experienced the smoke alarm going off while we’re cooking. Sometimes, we need to search for the source of that non-stop low-battery chirp at midnight,” said Fadell. “Therefore, every time a smoke alarm cries wolf, we trust it a little less, and then — in a moment of frustration — we take the batteries out to stop the beep（嘟嘟声）. And that leaves us and our families at risk.”
If the Protect smoke alarms are used, they can be set up in up to ten zones, so that the clear warnings tell users where the risk has been detected.
“Safety shouldn’t be annoying,” said Matt Rogers, Nest founder and vice president of engineering. “It was unacceptable to us that one in eight houses in the UK has a non-functioning smoke alarm. These products are required by law and are supposed to keep us safe, yet people hate them. We wanted to change that.”
【小题1】For what purpose did Nest create the Protect Smoke Alarm?
| A．To predict low-level fire risks. | B．To experiment with a new battery. |
| C．To improve present smoke alarms. | D．To avoid the low-battery chirp. |
| A．One of his cooking experiences. |
| B．Disadvantages of present smoke alarms. |
| C．His growing distrust of smoke alarms. |
| D．His source of annoyance to crying wolf. |
| A．a, b, c | B．c, d, e | C．a, c, e | D．b, c, e |
| A．In the UK people seldom set up smoke alarms. |
| B．Matt Rogers didn’t like the safety requirements. |
| C．Non-functioning smoke alarms make people annoyed. |
| D．The government should pay attention to safety issues. |

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 (冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) 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.
【小题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. |

Back in the early 1900s, American physician Byron Robinson wrote a book proposing an interesting theory: humans actually have two brains --- one in our heads and the other in our stomachs, and the two “communicate” all the time. Interestingly, in Chinese culture, thoughts are also related to the belly in phrases and idioms like fugao (腹稿, a draft), manfu jinglun (满腹经纶, a bellyful of ideas), and yiduzi weiqu (一肚子委屈, a bellyful of complaints).
This may sound a little ridiculous at first. But try to think of a time when you were extremely nervous. Chances are that you also felt uncomfortable in your stomach, didn’t you? This is probably why people use the idiom “butterflies in one’s stomach” to refer to being nervous.
Now scientists from Canada and the US have found that our guts (肠道), if not as bright as our actual brains, are much more than just where we digest the food we eat. They also affect our emotions and even behavior, all thanks to the bacteria in them, reported Scientific American.
In the study, scientists fed timid mice stomach bacteria from mice that were more active and daring. After eating the bacteria, the timid mice grew more energetic and fearless. Sure enough, when bold mice got the bacteria from timid ones, they became more anxious. The mice’s behavior also changed when scientists disturbed the bacteria in their guts by changing their diets and feeding them antibiotics (抗生素).
“If something goes wrong in the gut, that change is reflected in the brain,” Emeran Mayer, a professor at University of California, Los Angeles, told The Huffington Post.
The brain-and-gut connection also works in the opposite way. Scientists studied children with autism (自闭症) --- a mental illness that makes people unable to socialize with others --- and found that they also have a lot of stomach problems. They have fewer types of stomach bacteria and lower totals of a few key bacteria than healthy children.
This research raises the possibility that scientists could treat patients with brain problems simply by feeding them the right food, which would be much more efficient than providing psychological therapy (疗法).
According to CBC News, you can get “good” bacteria that lift your spirits from food like yogurt while “bad” bacteria are usually in high fat and high sugar foods.
【小题1】What is the author’s attitude toward Byron Robinson’s theory of two human brains?
| A．Unsatisfied. | B．Doubtful. | C．Positive. | D．Negative. |
| A．describe the symptoms of nervousness |
| B．suggest a connection between our stomach and our emotions |
| C．hint at the danger of nervous feelings |
| D．encourage people to calm down and relax |
| A．anxious | B．fearless | C．energetic | D．sharp |
| A．people with mental illnesses are more likely to have stomach problems |
| B．the use of antibiotics can turn timid mice into daring ones |
| C．timid mice have fewer types of stomach bacteria than daring mice |
| D．people must consider changing their diets when they feel anxious |
| A．psychological therapy has never worked before for autistic children |
| B．yogurt is the best solution for anxiety problems |
| C．high fat and high sugar foods are responsible for many mental diseases |
| D．diet changes can lead to mood changes |

A smart phone (智能手机) 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 (导航) units to form one multi-use device. Many modem smart phones also include touch screens and web browsers (浏览器) 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.
【小题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．addiction | 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. |

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(标识) in all their marketing which makes it clear that they are working towards cutting emissions，” Mr.Morrison said. (2010·福建，C)
【小题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．affect | B．change | C．disturb | D．reject |
| A．will benefit from cutting carbon emissions |
| B．should buy carbon allowances for shoppers |
| C．are required to make up for their carbon emissions |
| D．have encouraged shoppers to take their custom elsewhere |
| A．have a strong desire to reduce costs |
| B．use the same logo in their marketing |
| C．gain advantages by taking early action |
| D．attract more shoppers by storing goods |
