问答题For years, the prescription for maintaining health hearts had been vigorous exercise—running, swimming, dancing—whatever it took to get the heat rate up and keep it there for 20 to 30 minutes at least three times a week. But that message changed.
A panel of exercise researchers convened by the Centers for Disease Control and Prevention and the American College of Sports Medicine reported that people needn't exercise vigorously to improve their health.
The American Heart Association has weighed in with similar recommendations. But despite this apparent consensus, there is considerable disagreement in the exercise research community about whether the recommendations are amply supported by scientific data.
Policy-makers caught in the middle of this disagreement are in a difficult position. It's a classic dilemma confronting health experts in areas ranging from mammography (哺乳动物学) to diet, where the scientific data are not clear-cut.

问答题念书与读书【】到学校生活，像打一场仗，参与者身上装的，是各种掠夺分数的锦囊。考关一过，不管分数到手与否，一律把生吞活剥的知识忘掉。这种心态，书，真是用来念的，念过便算数，不必消化，更不必用心。会考结束那天，小女孩那帮人欢呼：可以把书丢掉啦！是典型的念书力证。把这种现象归于念书旗下，可捡来“小和尚念经，有口没心”一句撑腰，解释比较圆满。【】投入心思，广为涉猎，类比归纳、消化分析书中材料，不以分数为终极，才具备“读书”的起码要求。读书以兴趣出发，以诚意相许，读书只有歇脚小站，没有终点。【】读书是长途旅行，是开拓心灵的漫长陶冶过程；念书是短程旅游，是满足文凭欲望的虚幻纸笔战争。读书是春风化雨，修得一身气质，终身受用；念书是糊涂度日，走一段世俗小路，荒凉而乏善可陈。【】天底下念书的人多，读书者少。因为读书需要跋涉，讲究兴趣与耐力，缺一不可。

问答题Sir Richard Friend is a tough man to track down. Phone calls to his two labs at Cambridge University go unanswered, and so do e-mails. In the end, a reporter has to leave a note in his campus pigeonhole. The elusive Friend is the unlikely instigator of what may be a revolution in electronics: plastics. (46) Although most electronic devices make use of silicon chips, Friend sees a future in which mobile phones, TVs, watches, computers and other devices incorporate inexpensive plastic chips. (47) Friend's vision is based on his own discoveries, back in the '80s and '90s, that plastics can be used to make transistors, the basic element of chips, and light-emitting diodes (LEDs), which glow when electricity passes through them. His work has already yielded a new generation of lighter, thinner, brighter, cheaper and more flexible electronic screens for everything from lightweight mobile phones to disposable "talking" electronic greeting cards. (48) Now he's working on devices that might bring us talking cereal boxes or advertising posters that light up and speak as you walk by. The materials might even be spray-painted onto walls that change color with the weather, or go into pillboxes that tell you when to take your medication. It sounds farfetched, but the basic technology is already at hand. E-books with flexible screens that can be rolled up and put. into your pocket should start appearing in the next few years. (49) And plastic chips, which can be laid onto almost any surface, could be printed—just as ink is printed onto paper—onto any number of flexible surfaces. General Electric is working with the Department of Energy—to create large flexible sheets that could illuminate a room. If you think everything is digital now, just wait. (50) "Products in your fridge tagged with a chip would automatically change color after their sell-by date," says Peter Harrop, chairman of market-research firm IDTechEx. For his Cambridge students, Sir Richard has one word of advice: plastics.

问答题No one in fashion is surprised that Burberry burnt ￡28 million of stock A) Last week, Burberry’s annual report revealed that ￡28.6 million worth of stock was burnt last year. The news has left investors and consumers outraged but comes as little surprise to those in the fashion industry. B) The practice of destroying unsold stock, and even rolls of unused fabric, is commonplace for luxury labels. Becoming too widely available at a cheaper price through discount stores discourages full-price sales. Sending products for recycling leaves them vulnerable to being stolen and sold on the black market. Jasmine Bina, CEO of brand strategy agency Concept Bureau explains, "Typically, luxury brands rally around exclusivity to protect their business interests, namely intellectual property and preservation of brand equity (资产)." She stated she had heard rumors of stock burning but not specific cases until this week. C) Another reason for the commonplace practice is a financial incentive for brands exporting goods to America. United States Customs states that if imported merchandise is unused and destroyed under their supervision, 99% of the duties, taxes or fees paid on the merchandise may be recovered. It is incredibly difficult to calculate how much dead stock currently goes to waste. While there are incentives to do it, there’s no legal obligation to report it. D) A source, who chose to remain anonymous, shared her experience working in a Burberry store in New York in October 2016. "My job was to toss items in boxes so they could be sent to be burned. It was killing me inside because all that leather and fur went to waste and animals had died for nothing. I couldn’t stay there any longer, their business practices threw me off the roof." In May this year, Burberry announced it was taking fur out of its catwalk shows and reviewing its use elsewhere in the business. "Even though we asked the management, they refused to give us detailed answers as to why they would do this with their collection," continued the source, who left her role within two weeks. She has since worked with another high-profile, luxury label. E) In an online forum post, which asked if it’s true that Louis Vuitton burns its bags, Ahmed Bouchfaa, who claimed to work for Louis Vuitton, responded that the brand holds sales of old stock for staff members twice a year. Items which have still not sold after several sales are destroyed. "Louis Vuitton doesn’t have public sales. They either sell a product at a given price or discontinue it. This is to make sure that everybody pays the same price for an item," he says. He goes on to disclose the strict guidelines around the employee sales: "You may buy gifts for someone, but they track each item, and if your gift ends up online they know who to ask." One investor commenting on the Burberry figures was reportedly outraged that the unsold goods were not even offered to investors before they were destroyed. F) Richemont, who owns several luxury brands, hit the headlines in May for taking back ￡437 million of watches for destruction in the last two years to avoid marked-down prices. It’s not just luxury brands either. In October last year, a Danish TV show exposed H&M for burning 12 tonnes of unsold clothing since 2013. In a statement, the high street retailer defended itself by saying that the burnt clothing had failed safety tests: "The products to which the media are referring have been tested in external laboratories. The test results show that one of the products is mold infested and the other product contains levels of lead that are too high. Those products have rightly been stopped in accordance with our safety routines." In March, a report revealed that H&M were struggling with $4.3 billion worth of unsold stock. The brand told The New York Times that the plan was to reduce prices to move the stock, arguably encouraging consumers to buy and throw away with little thought. G) Over-production is perhaps the biggest concern for Burberry. While there has been much outrage at the elitist connotation of burning goods rather than making them affordable, executives at the British fashion house are no doubt struggling to defend how they miscalculated production. The waste has been put down to burning old cosmetic stock to make way for their new beauty range. However, while the value of destroyed stock is up from ￡26.9 million last year, it’s an even more significant increase from 2016’s figure of ￡18.8 million, highlighting that this is an ongoing issue. H) In September 2016, Burberry switched to a "see now, buy now" catwalk show format. The move was a switch to leverage on the coverage of their fashion week show to make stock available immediately to consumers. This is opposed to the traditional format of presenting to the industry, taking orders for production and becoming available in six months’ time. While Burberry announced "record-breaking" online reach and engagement, there has been little evidence to suggest that the strategy has had a significant effect on sales, particularly as the hype (炒作) slows across the season. In February they made adjustments to the format, dropping some catwalk items immediately and promising that others would launch in the coming months. I) In a statement, Burberry denied that switching to "see now, buy now" has had an impact on waste. A Burberry spokesperson further said, "On the occasions when disposal of products is necessary, we do so in a responsible manner. We are always seeking ways to reduce and revalue our waste. This is a core part of our strategy and we have forged partnerships and committed support to innovative organizations to help reach this goal." J) One such partnership is with Elvis & Kresse, an accessories brand working with reclaimed materials. Co-founder Kresse Wesling said, "Late last year we launched an ambitious five-year partnership with the Burberry Foundation. The main aim of this is to scale our leather rescue project, starting with off-cuts from the production of Burberry leather goods. We are working tirelessly to expand our solutions and would love to welcome anyone to our workshop to come and see what we are doing." At the moment, the partnership only addresses waste at the production stage and not unsold goods. K) While these are honorable schemes, it makes it harder for Burberry to defend these latest figures. Fifteen years ago, Burberry was at crisis point as their signature check pattern was widely imitated by cheap, imitation brands. It deterred luxury consumers who found their expensive clothing more closely associated with working-class youth culture than a prestigious heritage fashion house. In the year 2004, at the height of over-exposure of the Burberry check, the brand’s turnover was ￡715.5 million. Under Christopher Bailey as creative director they turned the brand around and this past year revenue hit ￡2.73 billion. L) Bina believes that brands need to readdress their exclusivity tactic. "Exclusivity is starting to be challenged," she says. "I think that goes hand in hand with how luxury itself is being challenged. Access to fashion, and the brands who police it, are becoming less and less relevant. Things like health, enlightenment, and social and environmental responsibility are the new luxuries. These all come from within, not without. That’s the challenge that traditional luxury brands will have to contend with in the mid- to long-term future."
