Boys'schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music．

    Far from the traditional image of a culture of aggressive masculinity(男子气概)，the absence of girls gives boys the chance to develop without pressure to be consistent to a stereotype(传统观念),a US study says．

    Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their abilities to express their emotions,rather than feeling they had to obey the “boy code” of hiding their emotions to be a “real man”.

    The findings of the study are against the received wisdom that boys do better when taught alongside girls．

    Tony Little，headmaster of Eton，warned that boys were being ignored by the British education system because it had become too focused on girls．He criticized teachers for failing to recognize that boys are actually more emotional than girls．

    The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills．

    But in single-sex schools teachers can adjust lessons to boys' learning style，letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James of the University of Virginia．

    Teachers could encourage boys to enjoy reading and writing with “boy-focused” approaches such as themes and characters that appeal to them．Because boys generally have sharper vision，learn best through touch, and are physically more active, they need to be given “hands-on” lessons where they are allowed to walk around.” Boys in mixed schools view classical music as feminine(女性的)and prefer the modern type in which violence and sexism are major themes.” James wrote.

    Single-sex education also made it less likely that boys would feel they had to give in to a stereotype that men should be “masterful and in charge” in relationships.“In mixed schools boys feel pressed to act like men before they understand themselves well enough to know what that means.” the study reported.

    The Humane Society of Utah,a non-profit organization,is the largest shelter in the state because it takes every animal that can be lawfully accepted.The shelter employed photographer Guinevere Shuster,from New York,who came up with a creative way to find new homes for the dogs.She took lively photos for them.

The 31-year-old created sets of four pictures showing the playful and serious sides of each animal.Guinevere Shuster tried her best to show these dogs the way they'd really look if you allowed them into your life.She said,"I'm always trying to imagine better ways to make the poor animals attractive to the public.The photos show their great personalities and are a much better way than presenting them as the sad dogs waiting to be taken home.I'm lucky because I get to connect the two things I love most,animals and photography."

Guinevere says she finds it easy to work with dogs.She said,"It's just me and the dog in the office so they can pay their attention to the photo-taking.I use a lot of treats and some funny noises I've learned to get the dogs' attention. A fun method is to throw treats at the dogs-it's useful for getting unusual looks from them."

    Since starting the project,a number of dogs have been taken home by dog lovers after they saw Guinevere's pictures on the Humane Society of Utah's Facebook page.In the last three years,she has photographed more than 4,000 animals.This year,the shelter has placed nearly 9,000 homeless pets into their permanent homes.

    Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard French Constant, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.

    The fridge is considered necessary. It has been so since the 1960s when packaged food list appeared with the label: "Store in the refrigerator."

    In my fridge less Fifties childhood, I was fed well and healthy. The milkman came every day, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times each w eek. The Sunday meat would last until Wednesday and the bread and milk left became all kinds of cakes. Nothing was wasted, and w e w ere never troubled by rotten food. Thirty years on, food deliveries have stopped, and fresh vegetables are almost impossible to get in the country.

    The invention of the fridge contributed comparatively little to the art of food preservation. Many well-tried techniques already existed — natural cooling, drying, smoking, salting, sugaring, bottling...

    What refrigeration did promote was marketing — marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.

    Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum (make a low continuous sound) away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house —while outside, nature provides the desired temperature free of charge.

    The fridge's effect upon the environment has been clear, while its contribution to human happiness has been unimportant. If you don't believe me, try it yourself, invest in a food cupboard and turn off your fridge next winter. You may miss the hamburgers, but at least you'll get rid of that terrible hum.
