Your Smartphone May Be Hurting Your SleepA) You love your smartphone, but it may be ruining your ZZZ’s. Use of these devices, especially near bedtime, is associated with worse quality of sleep, according to a new study. “When we looked at smartphone use around the time when participants reported they went to bed, more smartphone use around that time in particular was associated with a longer time to fall asleep and worse sleep quality during the night,” said Dr. Gregory Marcus, author of the study and an associate professor of medicine at the University of California, San Francisco. His research was published Wednesday in the journal PLOS One.B) The word “crack-berry” became popular roughly a decade ago to describe the addictive quality of BlackBerry devices—arguably the first really successful smartphones. Today, almost everyone is a smartphone junkie, standing with head bowed while waiting for a train or in line at the post office.C) Knowing that smartphone use has increased together with sleep deprivation rates, Marcus and his colleagues decided to investigate whether the two might be related. To answer this question, he used exiting information collected by an Internet-based study he started in March 2016.D) “Health E-Heart,” which was funded by the National Institutes of Health is designed to study cardiovascular health. Anyone 18 years of age or older can enroll in Health 11. Our addiction to smartphones dates back to about ten years ago._________ 12. Data from Health E-Heart are collected and used for researchers into heart diseases._________ 13. The findings of Dr. Marcus’s study appeared in PLOS One. _________14. Bad sleepers are advised not to use their smartphones half an hour or so before they go to bed. _________ 15. Marcus started his research because he suspected there might be some correlation between sleep loss and smartphone use. _________16. The use of digital devices affects children’s sleep too._________ 17. To make sure his study was objective, Marcus required his subjects to provide many more of their life details than just sleep hours and sleep quality._________ 18. Researchers found those who spend longer time playing with their smartphones are more likely to sleep badly._________19. Marcus conceded that some people were sleepless at night for reasons unrelated to mobile phone use._________ 20. Sleep is our basic biological need and lack of it may cause our body functions to decline. _________
There has been a definite, obviousimpact on the Earth’s climate by global warming. The unusual high frequency of heatwaves provesthat there has to be a human influence. As much of the USA burnsthrough another hotsummer and the Midwest suffers froma historic drought, NASA’s climateexpert Hansen states that the future he predicted in 1988 has finally arrived.Hansen and his colleagues have analyzed the frequency and scale of unusual temperature. On average, the Earth’s temperature has warmed by about0.5-0.6°C. Since then, the shift has impacted many parts of the world. Extremely hot summers, with a 3.5°C warmer temperature, have affected 10% of the world since 2006, which is muchhigher than the period of 1951to 1980.The possibilitythat these events would have occurred without global warming is very small. The study is purely statistical and doesn’t try to explain how climate changes have affected extremely hot summers. But it should help people understand global warming and the seriouseffect humans have on the climate system, states Kevin, a scientistat the US National Center for Atmospheric Research in Colorado.1.What did climate expert Hansen predict in 1988?A) Unusually high frequency of drought.B) Global warming’s influence on human.C) The unusual high scale of global warming.D) Frequency and scale of unusual weather events.2.What is the average temperature rise of the Earth since then?A) 3.5-4°C.B) 0.5-0.6°C. C) 0.5-1°C.D) 1.95-1.98°C.3.What should the study try to do?A) Help people avoid warmer summers.B) Help people understand global warming.C) Explain how climate changes lead to hot summers.D) Explain how the temperate shift has affected the world.

Read the following passage. Choose the best answer. Introducing the intelligent bicycleIn recent years, autonomous cars have received much media attention. However, intelligent bicycles are now a reality and are set to become more and more popular in urban areas. It’s easy to understand the reason behind the intelligent bicycle’s rise in popularity. The stresses and dangers of urban cycling have long been recognized. Urban cyclists have to be incredibly focused and aware of their surroundings when riding through busy cities, and the intelligent bicycle helps to relieve some of the pressure from their minds, by detecting threats and providing a kind of warning system in heavy traffic. The intelligent bicycle is able to warn its rider when a fast-moving, deadly object is nearby in order to prevent a fatal accident.How does it do this? The saddle and handlebars of the intelligent bicycle vibrate whenever danger is near: this helps cyclists order to be more aware of their surroundings and of any danger.Bicycle lights are becoming smarter too. Once they just flashed, now they can sense when you are at a junction, a roundabout or heading toward an approaching car. When they sense the situation needs extra light, they shine more brightly, keeping the rider safe.The intelligent bicycle also comes with a camera system that uses image processing to detect multiple vehicles at the same time. If intelligent bicycles continue to evolve in this way, accidents could become a thing of the past.(1) (单选题)What is the purpose of this article? A.To point out the dangers of intelligent bicycles.

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.

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
