Many editors have a rule that they will not even read stories that are not formatted and presented as requested in their Submission（投稿）Guidelines.Even if this policy is not stated,it affects their decision-making.There are a few reasonable reasons.

    A good editor likes to read all stories for the first time in the same format（格式）as the publication standard.A consistent format between manuscripts（手稿）removes distractions like unusual presentation and puts each manuscript on the same starting level,with the focus on content.

    Leading publications get thousands of submissions a year.Editor time is extremely valuable.Most editors enjoy finding gems among the manuscripts,but they really dislike reformatting(don't you prefer eating an elegant meal to washing dishes?).When an editor sees he will have to spend an extra half hour of precious time in reformatting,he subconsciously marks that submission down compared to other submissions of equal quality.

    Publications need to have consistency in formatting for all their published stories: letterform,type size,spacing, paragraph structure etc.This keeps the reader's focus on the words and not their structure.Since editors don't have a choice to just accept a weirdly（古怪的）formatted story as it is,they are forced to either reformat or decline the submission.

    Publications use different software and other tools in their operations.Editors know what makes their system go smoothly.Many invisible software formatting structures between types of documents create disasters.

    Editors are not pedantic（迂腐的）.Their job is to find great material and expose those works to appreciative readers.Differently formatted manuscripts steal time away from that responsibility,which is bad for everyone.Editors love nothing more than finishing a read and thinking “Wow.A great story-AND it's cut and paste!"

    Lawns（草坪）are some of the most common things in the world until you really start thinking about them. That's when you realize that they make no sense. Why do people keep these uninteresting, pointless little plants outside their homes? They're not beautiful like flowers, they don't provide food and you have to take care of them constantly.

    Israeli bestselling author Yuval Noah Harari thought these deeds were weird too. He looked into their history and ended up with an interesting story.

    No one considered putting patches of grass outside their homes in ancient times. That changed in the Middle Ages, when French and English kings and nobles started putting patches of grass at their castle entrances.

    “Well-kept lawns demand land and a lot of work,” wrote Harari in his book. “In exchange, they produce nothing of value.” Peasants could never afford to waste their time or land on lawns, so these lawns were a perfect status symbol（身份的象征）for nobility（高贵）.

    When the Industrial Revolution began in the 18th and 19th centuries, the middle classes started being able to afford their own suburban（郊区的）houses. And guess what became the suburban status symbol? A perfectly kept lawn.

    The popularity of lawns continued to grow, taking over public event spaces and sports. In the past, people played sports on all kinds of surfaces—dirt, ice, sand. But in the last couple centuries, they made the switch to green grass.

    “Grass is nowadays the most widespread crop in the USA after corn and wheat,” Harari continued. Lawns spread beyond Europe and the U.S, and they're now status symbols around the world.

    Suburban people may not realize it, but they care for lawns just because centuries ago, French and English kings wanted to show off by intentionally planting something useless. It's strange that people should continue to spend so much time and money on what's really a leftover（遗留物）from the Middle Ages. When you plan your house, you can shake off（摆脱）the cultural leftover and imagine for yourself a rock garden or some other new creation.

    Are supermarkets designed to persuade us to buy more? When you enter a supermarket, the manager knows better than you: how you will behave — which way you will walk, where you will look, what will make you buy one product rather than another. When customers go into a shop, they naturally look to their left but move clockwise, towards the right. So supermarket entrances are usually on the left of the building. And the layout is designed to take shoppers around the store, aisle (通道) after aisle, from left to right. {#blank#}1{#/blank#}

    Fresh fruit and vegetables are displayed near supermarket entrances. {#blank#}2{#/blank#} Basic food like sugar and tea, are not put near each other. They are kept in different aisles so customers are taken past other attractive foods before they find what they want. In this way, shoppers are encouraged to buy products that they do not really want.

    People walk quickly through narrow aisles, but they move slowly in wide aisles and give more attention to the products. One best-selling position for products is at the end of aisles, because shoppers slow down to turn into the next aisle. {#blank#}3{#/blank#} Supermarkets are paid by food companies to put their products in each of these high-selling places.

    {#blank#}4{#/blank#} While parents are waiting to pay, children reach for the sweets and put them in the trolley.

    More is bought from a fifteen-foot display of one type of product (e.g. cereal, washing powder) than from a ten-foot one. {#blank#}5{#/blank#} They do not like to buy from shelves with few products on them because they feel there is something wrong with those products that are there.

A. Another is on shelves at eye level.

B. Sweets are often placed at children's eye level at the checkout.

C. There are always enough products prepared for customers in the supermarket.

D. Then shoppers will pay attention to all the products.

E. This gives the impression that only healthy food is sold in the shop.

F. Customers also buy more when shelves are full than when they are half empty.

G. Supermarkets are one of children's favorite places and they are also big consumers.

    Are your eyes irritated, dry, watery, blurry, seeing double or sensitive to light, and do your back and neck ache? If so, you are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome.

    Eyestrain is often related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously. However, studies have also shown that the blue light produced by digital devices today reaches further into the eyes than other kinds of light. This light actually assists attention during the day but can result in interrupted sleep patterns at night.

    Scientists have also said that eyestrain is not a necessary evil, even in a modern world that revolves around technology. Changing some simple details about your relative position to screens, such as staying about 60 centimeters away, will help. Also, avoid overhead and other direct sources of light, and use shaded lamps and window blinds while looking at digital devices instead.

    Beyond the way that relates to digital screens, there are also ways to change how you view screens that are helpful in combating eyestrain. To begin with, your computer screen should be high-resolution(高清的), at least 50 centimeters wide diagonally and may require a screen filter to decrease reflections. Also, be aware that "computer glasses", which cut down glare and blue light, are available and those contact lenses can increase the risk of eyestrain.

    Besides, to reduce your risk for computer-vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer workday. Many workers take only two 15-minute breaks from their computer throughout their day. According to a recent study, discomfort and eyestrain are significantly reduced when computer workers take four additional five-minute "mini-breaks" throughout their workday. And these additional breaks don't reduce the workers' productivity.

    Finally, many of us fall into bad habits while using digital screens that only worsen the effects of eyestrain. While viewing digital screens, many people blink one third less often than they usually do. Place a reminder on your computer to "blink" so that your eyes don't dry out. Also, rest your eyes' focusing muscles by using the 20-20-20 rule: Every 20 minutes, focus on something 20 feet away for 20 seconds.

    Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is trustworthy? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.

    The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guilt-proneness (内疚倾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given $1, which they can choose to give to Player2. Any money given to Player 2 is then automatically increased to $2.50. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a portion of the money to Player 1. The researchers found more guilt-prone people were more likely to share the money with Player 1. Actually, in follow-up studies, guilt-proneness predicted trustworthiness better than other personality qualities the researchers measured.

    Why might guilt lead to trustworthy behavior? The researchers found people who were guilt-prone also reported feeling an obligation to act in ethical (合乎道德的) and responsible ways while interacting (互动) with their partners in the game. People who are guilt-prone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again.

    Then, how can we use this research to ascertain whether someone is trustworthy? "One way to do this might be observe how they respond to experience regret," lead author Emma Levine, assistant professor at the University of Chicago Levine, explains. Another way is to ask them to describe a difficult dilemma they faced in the past, suggests co-author Taya Cohen, associate professor at Carnegie Mellon University. This is particularly effective, Cohen and her colleagues have found, because it allows us to see if they're concerned about the effects their actions have on others.

    Banff National Park is Canada's first national park. In 1883, on the Canadian Rocky Mountains, three railway workers discovered a natural hot spring, and from there the park was born. Nowadays, it is one of the world's popular tourist spots with great mountain scenery. Every year, millions of people visit it for its wonderful views.

Banff National Park is part of UNESCO's Canadian Rocky Mountain World Heritage site. Located in the heart of the Canadian Rockies, the park has perfect mountains like those on postcards. They are from 45 to 120 million years old, with the highest in the park, Mount Forbes, coming in at 11,850 feet.

    Banff National Park is 80 miles west of Calgary. Calgary's international airport is serviced by major national and international carriers with many flights arriving daily. Open year­round, it offers amazing wildlife viewing and sightseeing, plus many shopping and dining choices, any time of the year. Summer is popular for hiking, mountain biking and cycling, photography, and climbing. The best time for viewing the seasonal color is fall, when the trees turn yellow.

    In winter, the mountain makes exciting downhill (速降) and cross­country skiing. In fact, three major downhill ski resorts (度假胜地) operate within the park. Lake Louise Ski Resort, Sunshine Village, and Mount Norquay combine to offer a large area for skiing, not to mention the backcountry trails available throughout the park. The ski season, which runs from November to May, is one of the longest in North America. Visitors can also enjoy wildlife tours, ice walks, and dogsleds (雪橇).

    Weather in the Canadian Rockies can change quickly. A single day can have a mix of sunshine, snow, wind, and rain, so you should change your clothes. In summer, temperatures average a high of 70 (21 ℃), and daylight lasts until 11 p. m. Autumn brings cool nights and fresh air. Winters can be very cold. In January, the average temperature is 7 ℃ below zero, but by April it is 9 ℃.
