Most evenings, before watching late-night comedy or reading emails on his phone, Matt Nicoletti puts on a pair of orange-colored glasses that he bought for S8 on the Internet. "My girlfriend thinks I look ridiculous in them," he said. But Mr. Nicoletti, a 30-year-old consultant in Denver, insists that the glasses, which can block certain wavelengths of light emitted by electronic screens, make it easier to sleep. Studies have shown that such light, especially from the blue part of the spectrum (光谱),inhibits the bodyˈs production of melatonin(褪黑激素),which helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night. A Swiss study of 13 teenage boys, published in August in The Journal of Adolescent Health. showed that when the boys wore orange-colored glasses, also known as ˈblue blockersˈ and shown to prevent melatonin, in the evening for a week, they felt "significantly more sleepy" than when they wore clear glasses. The boys looked at their screens, as teenagers tend to do, for at least a few hours on average before going to bed, and were monitored in the lab. Older adults may be less affected by blue light, experts say, but blue light remains a problem for most people, and an earlier study of 20 adults aged 18 to 68 found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses, which blocked only ultraviolet(紫外线)light. LEDs used in devices such as smart phones, tablets(平板电脑) and televisions tend to emit more blue light than incandescent products(白炽产品).LEDs are also increasingly popular as room lights, but "warm white" bulbs, with less blue, tend to be a better choice than "cool white" for nighttime use. The lighting company Philips also makes a reduced-blue LED bulb, meant to be usedbefore bedtime. "In theory, anything that will decrease that blue light exposure at night will be helpful." said Christopher Colwell, a scientist at the UCLA, "I know some gainers who swear by those orange-colored glasses." But orange glasses are not a panacea(万能药).Dr. Skene said. "It isnˈt just getting rid of the blue and everythingˈs fine," she said. The intensity of light, in addition to color, can affect sleep, she said, and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep. During the daytime, experts say, exposure to blue light is good. Best of all is sunlight, which contains many different wavelengths of light. "Thatˈs what our brain knows," said Kenneth P. Wright Jr., director of the sleep and chronobiology(生物钟学)lab at theUniversityofColorado, Boulder. A 2013 study he led, published in the journal Current Biology, showed just how different things can be without nighttime lights. After participants had camped in the mountains for a week, their bodies began to prepare for sleep about two hours earlier than normal. Short of cutting out all evening electronics, experts say, itˈs advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device. "If you can look at the iPhone for 10 minutes rather than three hours, that makes a lot of difference," Dr. Skene said.【小题】(1) What does the underlined word "inhibit" in Paragraph 3 probably mean?A.promoteB.projectC.preventD.process【小题】(2) Which of the following statements is true?A.The older a person is, the less he or she will be affected by blue light.B.The exposure to the blue light does nothing but harm to the human body.C.Traditional lighting companies are facing a dead end due to backward technology.D.All brands of orange-colored glasses are not reliable for their ability to aid sleep.【小题】(3) What are the contributing factors of a better nightˈs sleep? ①Limited screen time before bed. ②A pair of color glasses. ③A small-sized screen of electronics. ④A place without nighttime lights. ⑤Devices with LED backlighting.A.①②③B.①③④C.③④⑤D.②③⑤【小题】(4) The purpose of this article is to _.A.introduce a kind of orange glasses that may help people sleep betterB.advertise a brand of orange-colored glasses which can block blue lightC.question the effectiveness of orange-colored glasses on the marketD.teach readers about the most effective ways to have a better sleep.

  • question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

  • The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

  • The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
