The book ABigFatCrisis: TheHiddenForcesBehindObesityEpidemic— andHowWeCanEndIt by Deborah Cohen, a senior natural scientist, is very popular now. {#blank#}1{#/blank#} But according to this book, the following are some misunderstandings of obesity or being overweight.

1)．If you're obese, blame your genes.

    {#blank#}2{#/blank#} Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2)．If you're obese, you lack self­control.

    Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. {#blank#}3{#/blank#} Even, the most vigilant(警觉的)people may not be good controllers of themselves.

3)．{#blank#}4{#/blank#}

    Although the US Department of Agriculture estimates that fewer than 5 per cent of Americans live in the “food deserts”， about 65 per cent of the nation's population is obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4)．The problem is not that we eat too much, but that we don't exercise.

    Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. {#blank#}5{#/blank#} In fact, although a drop in work­related physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.

    Most visitors come to the UK expecting the rain and weather for which the country is famous. However, when summer finally arrives, British people like nothing more than heading for the coast. Here are some of more famous places of interest that you could expect to visit on a trip to Britain. Black pool, in the northwest of England, is the most visited place in the UK. Each year around 6.5 to 7 million people come to enjoy the miles of sandy beaches, the 158m Black pool Tower and the 11km-long Golden Mile, where there are entertainments, pubs, ice rinks (溜冰场) and even a zoo. On the south coast of the country you can find Brighton. Until 1786, Brighton was a sleepy village. Then the future king, George IV, decided to build a house there, and now it has become a large, international centre. Apart from the beaches, Brighton is famous for its pier (码头). There are theatres, entertainments and restaurants there. Brighton is also fantastic for shopping. If you want to travel a little further, why not go to Cornwall in the far southwest of the UK? South Cornwall offers miles of sandy beaches and beautiful scenery. The climate there is warmer than the rest of Britain, and you can even find palm trees. For a bit more excitement, go to North Cornwall. The scenery there is nicer, and the beaches are famous for their powerful waves. As a result, North Cornwall has become the home of British surfing. One word of warning though, if you are using the roads in the UK during holidays, you can expect long traffic jams on the motorways. It might be better to take the train.

    Ever get that feeling you're being watched? Well, if you're a dog-owner, you may have a point. Dogs are able to watch people's interactions with one another to determine who holds yummier treats, according to a new study. This study joins others that show dogs are good observers of human behaviors and feelings. It offers evidence that dogs use information not only from people's direct interactions with them, but also their interactions with one another.

    In the study, dogs watched a man ask two women for some of their corns. Both women gave the man corns when he asked, but in response to one woman, the man showed his enthusiasm and said the corns were so delicious. In response to the other woman, he gave the corns back and called them gross（in Spanish；the study was conducted in Argentina）. After these interactions, the man left and an assistant holding the dog let the dog go. While many dogs didn't approach either woman, the dogs that did have a preference tended to prefer the woman with the yummier(美味的) food.

    Other studies of dogs' people-watching ability have found dogs are able to tell the difference between happy and sad faces in their owners. They prefer people who give others food when asked over people who don't give others food. And in one study, dogs turned toward crying people more often than toward talking people.

    So how much do dogs really understand about the humans around them? That's not totally settled yet. In a strange twist to the Argentine study above, when the researchers tried an experiment in which they put two plates of corns on a table and had a man react to each plate, dogs didn't preferentially approach the tastier plate afterward. You could say dogs watch for the interaction between two persons, not just how a person reacts. Yet a previous study found dogs will choose boxes that people reacted to happily, but not boxes people reacted to with a disgusted face.

    Well, either way, you can be sure Fluffs is keeping an eye on you, to the best of her ability. The study was published in the journal PLOS One.

    Encouraging pupils to keep noise to a minimum should be a valuable part of all children's education, according to a new research.

    Dr. Helen Lees, from Stirling University's school of education, says that “enforced (强制的) silence” is seen as a punishment and often acts to suppress children's natural ability. But she says that teaching children about the benefits of “enforced silence” — deliberate stillness that gives them the opportunity to focus and reflect in a stress-free environment — can have a significant effect on pupils' concentration and behaviour.

    It is the latest in a string of researches to establish a link between the classroom environment and pupils' academic ability.

    A study almost a decade ago in London found that children's exam results were cut by as much as a third if they taught in noisy classrooms. Teaching unions have also called for a     limit of 26℃ to be put on classroom temperatures because teachers and pupils struggle to work in hot conditions and some educationalists claim that too much clutter(杂乱的东西) on classroom walls can prevent children from concentrating.

    Dr. Lees said: “When we take some research on school settings and put it all together, what we see is that education without silence does not make much sense. In areas of better learning outcomes, better self-confidence and well-being measures, enforced silence in a person's life and an individual's education is shown throughout the relevant research to be a benefit.”

    Dozens of schools across Britain already introduce periods of “reflective silence” into the timetable.

    Kevin Hogston, head of Sheringdale Primary, south London, has just introduced a minute's silence at the start of twice-weekly meetings in which children are taught breathing techniques and encouraged to reflect. The school plans to introduce it into classrooms every day.

    If you want to become a fluent English speaker you should take some advice. There are four skills in learning English. They are reading, listening, speaking, and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills, you should first master the skills of reading and listening.

    Read as much as you can. But your reading must be active. It means that you must think about the meaning of the sentence, the meaning of the unfamiliar（不熟悉） words, etc. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you come across, but the fact that you see them for the first time and recognize them whenever you see them, for example, in other passages or books, is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it.

    As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading, then you can catch up on your listening. Since you have lots of inputs in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice listening.

    For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or if you are good at listening you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes.

    If you follow these pieces of advice, your speaking and writing will improve quickly, and you can be a fluent English speaker one day.

    The number of snow geese arriving in the Arctic each spring to breed has risen over the past few decades. At first, wildlife biologists saw this as an environmental crisis, pointing to marshes（湿地） where plants were eaten by the hungry birds. In response, the federal government loosened restrictions on snow goose hunting.

    But how do the Inuit, in whose backyard this is taking place, view the situation? A recent plan is giving Inuit wildlife experts the opportunity to lend their knowledge to managing the species. The snow goose study, which is supported in part by Polar Knowledge Canada and led by the Kivalliq Wildlife Board (an Inuit organization that manages hunting, trapping and fishing in central Nunavut), asked the experts to share their generations of knowledge about snow geese and their views on what should be done.

    “The community had concerns about controlling the population,” says Ron, a community officer of the Kivalliq Inuit Association, “and Inuit snow goose knowledge had never been recorded. People wanted to pass on what they knew.” Inuit experts disagreed with that, considering it wasteful and unnecessary. They felt hunting more snow geese in an organized way, such as paying local hunters a minimal amount of money and distributing the birds to disadvantaged families or operating a limited commercial hunt by employing local people, would be appropriate.

    Inuit wildlife experts will plan to call on scientists this fall. They say they hope to search for a common way forward and that while there may be too many snow geese in some areas, it's not a crisis. Biologists now generally agree that there seem to be plenty of undamaged marshes available and newer research shows that some damaged areas can recover.

    “Now that we have recorded and documented Inuit knowledge of snow geese,” says Ron, “when facing the crisis other people will be able to use the information to help manage the species, which is fundamental to dealing with it effectively.”
