    Is your family interested in buying a dog? A dog can be a pleasant companion（伙伴） to your family, but if you choose the wrong kind of dog，you will have a lot of troubles.
    Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds(种类)you should know that a dog described(描述)as very alert(机敏灵活的)may be too active. When a book describes a dog as an excellent hunting dog, it probably means that the dog won’t be happy living in a small house. Dog breeds vary(变化)in popularity as the years go by. One of the most popular dogs these days is the German shepherd（牧羊犬）. This is because it provides protection as well as companionship（陪伴）. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to control. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don’t need to be walked daily, since they can exercise in the home.
    小题1:According to the passage, one can get information about different kinds of dogs      .
    A．by going to the library
    B．by asking someone who has enough experience about different kinds of dogs
    C．by buying a dog and training it
    D．by reading books about dogs
    小题2:The German shepherd is a popular dog      .
    A．because it is easy to train
    B．because it is big and strong
    C．because it is powerful and friendly
    D．because it is alert and active
    小题3:Which is the best topic of the passage?
    A．The care and proper selection of dogs for families.
    B．Different breeds of dogs.
    C．Responsibility for seeing that dogs are properly cared for.
    D．Different kinds of books about dogs.

    小题1:D
    小题2:C
    小题3:A

    试题分析：本文主要讲述的是如何选择宠物狗以及照顾这些狗。
    小题1:D 细节题。根据文章第二段3,4行If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog.可知我们可以通过阅读来了解更多的关于狗的知识。故D正确。
    小题2:C 细节题。根据文章倒数3,4行One of the most popular dogs these days is the German shepherd（牧羊犬）. This is because it provides protection as well as companionship（陪伴）.可知德国牧羊犬受欢迎是因为它们可以提供保护和陪伴。故C正确。

    Speaking two languages rather than just one has obvious practical benefits in an increasingly globalized world．But in recent years, scientists have begun to show that the advantages of bilingualism （双语能力） are even more important than being able to converse with a wider range of people．Being bilingual, it turns out, makes you smarter．It can have a deep effect on your brain, improving skills not related to language and even protecting against a serious mental disorder in old age．
    This view of bilingualism is different from the understanding of bilingualism through much of the 20th century．Researchers, educators and policy makers long considered a second language to be an interruption that prevented a child's school work and ability to think and understand things．They were not wrong about the interruption: there is ample evidence that in a bilingual \s brain both language systems are active even when he is using only one language, thus creating situations in which one system disturbs the other．But this interruption, researchers are finding out, isn't so much a disturbance．It forces the brain to solve inside conflict, giving the mind a workout that strengthens its thinking muscles．
    The key difference between bilinguals and monolinguals may be more basic: a heightened ability to monitor the environment．"Bilinguals have to switch languages quite often—you may talk to your father in one language and to your mother in another language," says Albert Costa, a researcher at the University of Pompea Fabra in Spain．
    "It requires keeping track of changes around you in the same way that we monitor our surroundings when driving．" In a study comparing German-Italian bilinguals with Italian monolinguals on monitoring tasks, Mr．Costa and his colleagues found that the bilingual subjects not only performed better, but they also did so with less activity in parts of the brain involved in monitoring, showing that they did better in it．
    小题1:From the passage we can learn that experts used to believe that ______．
    A．interruption forced a bilingual's brain to strengthen its thinking ability
    B．a second language stopped children's studying as well as mental development
    C．using two languages annoyed the children who have trouble in learning skills
    D．language systems were busy in a bilingual's brain when he was using languages
    小题2:The underlined word "switch" in Paragraph 3 probably means "______"．
    A．changeB．useC．speakD．study
    小题3:What is the author's attitude towards bilingualism?
    A．Cautious．B．Doubtful．C．Concerned．D．Favourable．
    小题4:Which of the following would be the best title for the passage?
    A．How Bilinguals Use Languages
    B．What Bilingualism Is Really about
    C．Why Bilinguals Are More Intelligent
    D．When People Learn a Second Language

    The scientists observed that the more junk food the rats ate, the more they wanted to eat – a behavior very similar to that of rats addicted(上了瘾的) to heroin, a dangerous drug. Johnson said the experiment shows that the brain chemistry of obesity(肥胖) and drug addiction may be quite similar.
    In their experiment, Johnson and his team studied the “pleasure center” of rats’ brains. The pleasure center is a complicated network of nerve cells. If the animal exercises or eats, the cells reward the animal by releasing chemicals into the body that make it feel good. And when the body feels good, the animal – or person – will want to do the behavior again.
    For the experiment, Johnson fed foods like cheesecake to one group of rats. Food like this is high in calories and fat. Another group of rats got a regular diet. The rats that ate junk food started to eat more and more.
    “They’re taking in twice the amount of calories as the control rats,” says Paul Kenny, one of Johnson’s colleagues.
    Kenny and Johnson wanted to know what was going on in the brains of these rats. They first designed a way to deliver a small electrical charge to the rats’ brains. This electrical charge would stimulate the pleasure centers to release pleasure-causing chemicals. The rats could control how much stimulation – and how much pleasure – they received by running on a wheel. The more the rat ran, the more pleasure it received.
    The rats that had been eating junk food started running more and more. This behavior suggested that the junk-food-eating rats needed more brain stimulation to feel good compared with rats on a normal diet. In other words, their pleasure centers were becoming less sensitive and the junk food didn’t make them feel good unless they ate more and more.
    Experiments like this one could help scientists understand how chemicals in the brain contribute to obesity. With that information, they may be able to help people avoid obesity in the first place.
    (Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)
    小题1: The scientists suggested it was actually ___________________ that made the rats feel good.
    小题2: How did the scientist know what was happening in the brains of the junk-food-eating rats?
    小题3:What was the purpose of the experiment mentioned in the article?

    [1] More than 40 million Americans move each year, but not always by choice. Whether you relocate because of a new job or school for you or your spouse, for a lower cost of living, or for better opportunities, adjusting to life in a new place can be scary and difficult--especially when you’re not in love with your new city. Here are some tips on how to make the most of your relocation and find happiness in your new home.
    [2] Treat it as an adventure
    Living in a new place is a great opportunity to experience new things and to grow as a person. So stay positive, and get out there and explore! Sample the local cuisine. Visit landmarks and museums. Try local activities that weren’t available or popular in your former city, such as skiing if you came from a beach town or surfing if you lived in the mountains. You may discover a talent or interest you never knew you had.
    [3] Get involved
    Attend local events that interest you. Visit the weekly farmer’s market or the neighborhood yard sale. Volunteer. Take a class. Join a sports league. All of these things will help you meet people and feel connected to your new town.
    [4] Locate the necessities
    Driving, riding, or walking around your new neighborhood is the best way to learn where everything is. So head out and take note of the nearest supermarket, pharmacy, post office, library, etc.
    [5] Keep pieces of your old home
    To keep from getting too homesick, subscribe to your former city magazine or newspaper. Display photos of or souvenirs from your favorite places in your old town. Hang decorations from your former home. Just don’t go overboard—hanging on to too much from your past will keep you from moving forward and really enjoying your new home.
    [6] _________
    It takes time to get to know a new place, so don’t expect to feel comfortable right away. Give yourself time to adjust. To help the process and to meet new people, find a support group near you at Just Moved.org.
    小题1:What does the passage mainly talk about? (within 15 words.)
                                                                                      
    小题2:What does the underlined word “it” in the last paragraph refer to? (within 7 words)
                                                                                      
    小题3:According to the passage, what can you do to learn where everything is?( within 5 words)
                                                                                      
    小题4:Fill the blank with proper words. (within 5 words)
                                                                                      
    小题5:If you are a new comer, where to find a support group near you based on this passage? (within 3 words)

    Imagine going to sleep then waking up speaking another language. It may sound impossible， but it's actually happened.
    The phenomenon(现象)of being able to suddenly speak another language is known as“Xenoglossia”， from the Greek words“xenos”(foreigner)and “glossa”(language)．
    It once happened to a 13­year­old girl from Croatia. After being unconscious(不省人事的)because of a disease for 24 hours in 2010，she woke up speaking fluent German. The girl， who came from the town of Knin in the south of Croatia，was studying German at school but she'd only started recently. Her parents said that she'd been reading German books and watching German TV at home， but that she wasn't fluent in the language.However ，since waking up， she's been able to communicate “perfectly”in German.What's really strange is that she's now unable to speak Croat，her mother language.Doctors at Split's KB Hospital have asked some experts to examine the girl as they try to find out what caused the change.Dr Mijo Milas said，“In earlier times this would have been considered as a miracle(奇迹)；we prefer to think that there must be an explanation—it's just that we haven't found it yet.”
    In 2007，Matej Kus from Czech became unconscious after a motorbike accident. On waking up 45 minutes later，he could speak fluent English.Matej was only 18 years old at the time， and had just started studying the language and so was at a low level.Peter Waite，Kus's teammate said，“I couldn't believe what I was hearing.It was really clear English.It was unbelievable to hear him talk in unbroken English.”Unluckily，Matej's new language skills didn't last.Two days later， when he recovered fully from the accident， he'd completely forgotten his English.
    We still don't know exactly what happened to the two people. Perhaps scientists will discover something new and exciting. But until then， keep studying!
    小题1:According to the passage，what is“Xenoglossia”？
    A．That someone becomes unconscious.
    B．That someone speaks a new language in a sudden.
    C．That someone doesn't like his mother language.
    D．That someone is able to speak Greek suddenly.
    小题2:What does the underlined word “It” in Para.3 probably refer to?
    A．Having accidents.
    B．Speaking fluent German.
    C．The phenomenon of Xenoglossia.
    D．Being unable to speak.
    小题3:We can learn from Paragraph 3 that the girl from Croatia ______.
    A．wanted to know what caused her change
    B．believed she had a talent for language
    C．didn't study German for a long time
    D．didn't like learning German
    小题4:Which of the following is TURE according to the test?
    A．Matej Kus is now afraid of motorbike racing.
    B．The girl from Croatia lost consciousness for several days.
    C．The girl from Croatia was knocked unconscious in an accident.
    D．Matej Kus could only speak a little English before the accident .

    When was the last time you did something really fun with one of your parents—just the two of you?     
    Parents who take their young children to music, swimming and art classes often stop arranging such activities once their kids are older and in school all day. But it doesn’t have to be that way. Doing something enjoyable with your kids just might make you look at each other in a whole new way, especially if you do it through a class or an event. When parent and child become students together, it puts them on the same level, at least for a while. 
    “I really like parents to come to class with their kids—they start sharing things and talking about what they’re doing and what they like,” said art teacher Pyper Dixon.     
    However, finding something new in common is a big choice for them, especially when kids get involved in sports and other after-school activities. But it’s possible to learn a new skill or hobby together.     
    That’s certainly true of Lauren, 11, of Silver Spring, who is in Dixon’s class with her father, Dennis. “I was just going to drop her off,” Dennis said, “but Dixon persuaded me to stay.” 
    Now Lauren gets to nag her father about doing his art homework. “He always leaves it to the last minute,” she said. “But then he’ll turn around to do amazing drawings,” she added, “We have different styles of drawing, so it’s interesting to talk it over with him.”     
    Without the Saturday morning art class, Dennis said, he would be reading the paper, and Lauren would be on her own in her room or on the computer. But they talk more now. “I can’t think of an experience where you communicate with your kid so closely,” he said.
    小题1:The author raises the question at the beginning to_______.
    A．expect an answer
    B．criticize some parents
    C．introduce the topic
    D．support his argument
    小题2:What does Dixon think is the benefit of parent and child studying art together?
    A．They will become equal.
    B．They will communicate more.
    C．The child will learn art much better.
    D．The parent will learn something new.
    小题3:The underlined word “nag” in the text probably means _______.
    A．urge
    		B．help
    		C．miss
    		D．teach
    小题4:We can learn from the text that_______.
    A．Lauren used to talk a lot with her father
    B．Dennis enjoys studying art with Lauren
    C．Lauren dislikes her father’s drawings
    D．Dennis likes playing computer games

    One of my China Dialogue colleagues in Beijing recently bought a Philips energy-saving light bulb to replace a standard one．He was happy with his choice．It may have cost 30 yuan （just under US$4．50） - ten times the price of a filament （灯丝） bulb - but he wanted to save energy as part of his low-carbon lifestyle．And according to the shopkeeper, he would save, in the long run, much more than the 30 yuan he was spending．
    Yet only one month later, his expensive light bulb blew up, before he had saved even a small part of the purchase price．Will he stick to his high-cost, low-carbon lifestyle?
    China's environmental organizations have started to advocate low-carbon lifestyles and the decrease of carbon footprints to help fight against climate change．But they have overlooked one fact: in China, low-carbon living comes at a high cost．It means buying energy-saving bulbs and appliances, and environmentally friendly building materials and daily goods．Cost can no longer be the only standard for purchases．An energy-saving and environmentally friendly product is more expensive than a standard alternative - whether it's a simple light bulb or the house it shines．For average consumers, even buying an ordinary bulb is a huge burden．How can we persuade ordinary people to choose an energy-saving residence? This is not a trend they can afford to follow; perhaps this fashion is only for the rich．
    Most consumers today do not cause huge carbon dioxide （CO2） emissions．Their responsibility lies not in choosing a low-carbon lifestyle today, but in avoiding a high-carbon life in the future．The principle of "common but differentiated responsibility" - a basis of sustainable development - can be applied here as well．
    In China, low-carbon living still is resisted by a lack of social infrastructure（基础设施）. Even if your salary allows you to make that choice, nobody is there to help you accomplish it．
    Consider energy-saving homes. You need to find out whether or not the developer has used natural materials wherever possible; how effective the insulation（绝缘物、隔热物） is; and what the green credentials of installed equipment are．You can read up a little, but you'll still be lucky to avoid being puzzled by the developers' marketing．Many so-called energy-saving buildings are nothing of the sort, and some are even more energy-hungry than the average home - as Li Taige warned in his article "Energy-efficient buildings? Not always", on China Dialogue last August．
    小题1: What may probably be the best title of this passage?
    A．To purchase a cheap bulb - your wise alternative．
    B．To choose an energy-saving residence - a must of your life
    C．To learn a low-carbon lifestyle - each citizen's responsibility
    D．To learn a low-carbon lifestyle - a promising but difficult purpose
    小题2:Why does the writer say this fashion is only for the rich in the fourth paragraph?
    A．Because the cost is a very important standard for purchases.
    B．Because buying an ordinary bulb is very expensive.
    C．Because energy-saving products are more expensive than the common alternatives.
    D．Because rich people like to follow this trend.
    小题3: What does the writer think of energy-saving homes?
    A．Most of them are environmentally friendly.
    B．They are musts of low-carbon lifestyle of Chinese.
    C．They are huge burdens for Chinese people.
    D．Many of them are more in name than in reality.
    小题4:We can infer from the passage that ____．
    A．Using energy-saving bulbs and appliances is a fashion．
    B．It's easy for most Chinese to try to learn a low-carbon lifestyle．
    C．All citizens in China don’t have the same responsibility in living a low-carbon lifestyle．
    D．Most Chinese families cannot afford to purchase an energy-saving residence.
    小题5:What is the writer's attitude towards the low-carbon lifestyle?
    A．informative and entertainingB．supportive but cautious
    C．negative but wiseD．positive and active
