He took a deep breath and decided to plunge himself ____ the adventure, leaving behind the familiar for the thrill of the unknown.

An entire industry has been developed to provide educational DVDs designed for infants. These DVDs are marketed as able to facilitate the development of various cognitive (认知的) skills such as language. An academic journal recently published a study that focused on one product, the Baby Wordsworth, from the Walt Disney Company's Baby Einstein series. The study put the DVD to the test with a group of one- and two-year-olds. For six weeks, 88 children were randomly (随机地) assigned to either watching it a few times a week or not at all. Researchers then tested the language skills in each group based on how many words the children knew. At the end of the period, children in both groups understood about 20 of the 30 words highlighted in the DVD, on average. The researchers also asked parents about their children's television viewing before entering the study. The earlier a child started watching Baby Einstein DVDs, it turned out, the smaller his or her vocabulary was. The study's finding is in line with some earlier research, says Rebekah Richert, a researcher at the University of California, who led the study, but it is unclear if the DVDs themselves are responsible. "Parents who place their kids in front of the screen could be trying to remedy slow language development, or they could be using the DVDs as baby sitters, cutting back on social stimulation." "A lot of children seem to have these kinds of DVDs," Richert says. "My take-home message would be to encourage live interaction between parent and child." Although it is not well understood how watching television affects language, Richert and his colleagues wrote in their report, the American Academy of Pediatrics (儿科) recommends that children younger than two stay away from the screen. The Baby Einstein Company emphasized that it "does not claim educational outcomes." On its web page, it notes that its products "are not designed to make babies smarter but to engage them." The company notes that it disagrees with the recommendation from the American Academy of Pediatrics. "When used properly," the company writes, "appropriate video content can be a useful tool for parents and little ones to enjoy together."1. Researchers conducted the study with the Baby Wordsworth DVD in order to ________.A) examine the quality of the DVD from the Baby Einstein CompanyB) reveal the difference in language learning ability between babiesC) find out whether the Baby Wordsworth DVD can boost language skills D) find out how many words babies can learn from the DVD2. It can be inferred that the previous studies have suggested that ________.A) early exposure to DVDs can negatively impact language development B) watching baby videos can actually boost the children' language skillsC) baby videos are harmful to the cognitive learning of childrenD) DVDs of poor quality can not facilitate language development3. Which of the following is the possible reason given by Richert to explain the results of his study?A) Putting babies in front of educational DVDs kills their interest in language learning.B) Keeping kids watching DVDs reduces parents' verbal engagement with them. C) Children under two cannot concentrate on educational DVDs.D) Kids at an early age show no much difference in language learning.4. According to Richert, what is the most important thing for parents to do?A) Keeping infants away from the educational DVDs.B) Staying together with babies in front of the screen.C) Having more interaction with children in real life. D) Limiting the video watching time for young kids.5. What does the Baby Einstein Company say about its DVD products?A) They are helpful for the kids who have language delay.B) They are harmful to young kids without a proper use.C) They cannot help the language learning of young kids.D) They are not made to improve the intelligence of kids.

装何10. Types of Music Music can be divided into many types, such as country music, rock, jazz, classical music and so on. Which type do you love most?Whether you love pop music or not, maybe you have heard of the famous rock band, The Beatles.

What does the word “snowball” in Paragraph three most probably mean.第一次Why do smokers tend to weigh less than nonsmokers and gain weight when they give up the habit?Contrary to “common knowledge”, nonsmokers do not generally eat more than smokers, nor do they exercise less, studies find. Research performed on smokers at rest indicates that nicotine (尼古丁) itself can increase basal metabolic (新陈代谢的) rates, meaning smokers burn more energy than nonsmokers during periods of inactivity. But surveys suggest most smokers smoke not while completely at rest, but while performing light activities such as desk work that can increase metabolic rates by two or three times. Unless nicotine’s metabolic effects increase proportionally with metabolic rates, its influence on weight might be insignificant.Now a study shows that nicotine’s effects on body-fuel consumption indeed increase proportionally with increases in activity. “These results indicate that the metabolic effect of nicotine may play a greater part in accounting for body-weight differences between smokers and nonsmokers than was previously believed,” says Kenneth A. Perkins and his colleagues at the University of Pittsburgh School of Medicine.

New Formula One Chief Hopes to Grab Americans' AttentionA) For the past four decades, the leader of Formula One car racing, one of the biggest annual sporting series in the world, was Bernie Ecclestone, a former motorcycle parts dealer who built it into an international presence essentially on his own.B) A skilled backroom operator who speaks without a filter, Ecclestone said often that in his opinion, the sport was at its best when he was allowed to act as “a dictator.”C) Yet now the dictator is gone. After an American company, Liberty Media, acquired the Formula One competition recently, Chase Carey-a former executive with Fox Broadcasting Company and DirecTV who by his own admission is not a fierce racing fan-was named to replace Eccelstone and to try to renovate the organization's management, reach and ambition.D) Among the goals, Carey said in an interview on Tuesday, is one that just about every global sport seems interested in chasing; increasing interest in the United States. “People have said we're going to ‘Americanize’ it," Carey said. “And we're not going to do that totally. But realistically, there are some elements of Americanization that the sport could use.”E) While Formula One commands enormous audiences throughout much of the world, many American sports fans know it as that other motorsport, the one that is not Nascar (纳斯卡车赛). Formula One teams race far more technologically advanced vehicles around tracks all over the world-in magnificent events in places like Malaysia, Monaco, Singapore and the United Arab Emirates, and on tradition- rich tracks like Silverstone in England and Monza in Italy too.F) The series has an annual race in Austin, Texas. But within “a few years,” Carey said, he plans to bring another to a destination American city, like New York, Los Angeles, Miami or Las Vegas. Carey's ambitious plan is two-fold; first, change the business model of Formula One, which he said was a “one-man show” under Ecclestone that had a largely narrow vision when it came to negotiating partnership deals; and second, alter the way fans experience the sport, both in person and remotely, so that connections between the audience and people within the series are easier to make.G) Increased digital access for fans, a more behind-the-scenes experience for broadcast viewers and innovation in areas like virtual reality—what is it like to speed around a track inside a Ferrari? —are among the possibilities. “The sport has clearly been underserved,” Carey said. “It doesn't do anything digitally. There's no marketing. It doesn't tell any stories. The goal in this is to make the fans connect to the live experience as much as possible, and the tools you have to do that, we're not using at all.”H) The larger question, though, is a familiar one: Is there room for Formula One in the ever-crowded sports landscape of the United States? Opinions vary, particularly because viewing habits among consumers continue to evolve. John Bloom, a professor at Shippensburg University who has studied American sports history, said the biggest challenge for any sport trying to increase its presence in the United States was framing itself in a way that had lasting appeal. “Sports generally become popular in some way because they establish a narrative,” Bloom said. “When I think of motorsports in the U.S., what we all think of is Nascar, and the narrative of Nascar is sort of rural, white, working-class Americans, mostly in the South, connecting with the atmosphere of those races. That's the narrative. When I think of the narrative of Formula One, it's a very different kind of audience.” D That difference, Carcy said, is significant. While some might immediately link Formula One to Nascar in terms of American growth, Carey said Formula One's brand research had indicated there was very little crossover; rather, Formula One fans generally cite other so-called elite events, like Wimbledon or the Ryder Cup, as competitions they enjoy. “Other than they're both cars, the Nascar fan base is a very different fan base," Carey said. "It's a very regional fan base. Formula One is a global, famous brand of stars. These are machines that shock and awe you.”J) Carey's background is in deal making and innovation. At Fox Broadcasting Company, he was a top advisor for years, known for his skill in helping to lead the launch of the company into sports, as well as the start of Fox News Channel. After going to DirecTV, he positioned the satellite provider as a mainstream option in millions of households.K) Now, after Liberty Media paid 4.4 billion to acquire Formula One, he is charged with making the investment pay off. “I think they can build Formula One in the U.S.,” said Patrick Crakes, an executive at In Vivo Media Group who spent 25 years at Fox Broadcasting Company before leaving in 2016 as a senior manager at Fox Sports. “People don't work on their cars anymore. They don't want that connection anymore. It's about technology and pushing the limits. It's about speed, danger and risk. And Formula One has that more than any other racing series.”L) That is what hooked Carey, and he said he thought his experience was not unusual. He recalled attending Formula One's Monaco race last year and being overwhelmed by the ceremony leading up to the event, the way the race charmed the city for days ahead of the start. In his mind, it felt like a Super Bowl(超级碗橄榄球赛).M) Then, on race day, he watched as the cars rocketed out of a tunnel and went screaming toward a tight turn with the city's harbor and the Mediterranean Sea in the background framing the scene. He was fascinated. “You can't help but be awed,” he said, “and I think that feeling can be translated to the viewer.”N) He added: “The broader sport is a little too inward-looking, and we need to be more open. In some ways, I'm glad to be coming from the outside. The guys who are in the sport forever are sitting there saying: “We can't do that. We can't do that because it's never been done that way.” 36. Chase Carey believes greater use should be made of digital technology to make Formula One more accessible to its fans. 37. Chase Carey was deeply impressed by the ceremony preceding last year's Monaco race. 38. One of Chase Carey's goals is to make Formula One more appealing to Americans. 39.A former motorbike parts dealer led Formula One for the past forty years. 40. Chase Carey thought the audience of Formula One could be made to share his feeling about the race. 41. Chase Carey used to serve as a top advisor for a major broadcasting company. 42. Chase Carey intends to make connections easier between the audience and the Formula One racers. 43. The new leader of Formula One admitted he was not super interested in car racing. 44. People's opinions differ as to whether Formula One can be promoted in the U. S. 45. Compared with other racing series, Formula One focuses more on speed and involves more danger.
