11、Guthrie and Danica Patrick, first female Indy competitor and winnerNo complaints about woman drivers. Janet Guthrie, a space engineer who was training to be an astronaut, turned to car racing when she was cut from the space program for not having completed her doctors degree. In 1977, Guthrie became
12、 the first female Indy 500 competitor. She didnt take the lead, but Danica Patrick did. In 2005 and in 2008, Patrick became the first woman ever to win an Indy Car Series.Raymonde de Laroche, first female licensed pilotA former actress, whod been born in Paris in 1882, Raymonde de Laroche was inspir
13、ed to take up flying after seeing the Wright Brothers flight demonstrations in 1907 in France. Though she wasnt the first female pilot, de Laroche was the first woman to earn a pilots license in 1910.Gertrude Ederle, first woman to swim across the English ChannelOn August 6th, 1926, Gertrude Carolin
14、e Ederle became the first woman to swim across the English Channel.

18、s something in the elderly womans behavior that caught my eye. Although slow and unsure of step, the woman moved with deliberation, and there was no hesitation in her gestures. She was as good as anyone else, her movements suggested. And she had a job to do.The elderly woman had walked into the stor
19、e along with a younger woman who I guessed was her daughter. The daughter was displaying a serious case of impatience, rolling her eyes, huffing and sighing, checking her watch every few seconds. If she had possessed a belt, her mother would have been fastened to it as a means of dragging her along
20、to keep step with the rush of other shoppers.The older woman detached(分开) from the younger one and began to glance over the DVDs on the nearest shelf. After the slightest hesitation, I walked over and asked if I could help her find something. The woman smiled up at me and showed me a title written o
21、n a piece of paper. The title was unusual and a bit unfamiliar. Clearly a person looking for it knew a little about movies, about quality.Rather than rushing off to locate the DVD for the woman, I asked her to walk with me so I could show her where she could find it. Looking back, I think I wanted t
22、o enjoy her company for a moment. Something about her deliberate movements reminded me of my own mother, whod passed away the previous Christmas.As we walked along the back of the store, I narrated its floor plan: old television shows, action movies, cartoons, science fiction. The woman seemed glad
23、of the unrushed company and casual conversation.We found the movie, and I complimented her on her choice. She smiled and told me it was one shed enjoyed when she was her sons age and that she hoped he would enjoy it as much as she had. Maybe, she said with a hint of eagerness, he could enjoy it with
24、 his own young children. Then, reluctantly, I had to return the elderly woman to her keeper, who was still tapping her foot at the front of the store.I accompanied the older woman to the queue at the cash register and then stepped back and lingered near the younger woman. When the older womans turn
25、in line came, she paid in cash, counting out the dollars and coins with the same sureness shed displayed earlier.24. What does she had a job to do (Para. 1) mean according to the context?A. She had a regular job in the store.B. She wanted to ask for help.C. She wanted to buy a DVD.D. She was thinkin
26、g of what to buy.25. What does the title of the DVD reveal according to the shop assistant?A. The elderly woman had some knowledge about movies.B. The elderly woman liked movies for young children.C. The elderly woman preferred movies her son liked.D. The elderly woman liked both old and new movies.
27、26. While looking for the DVD with the old woman, the shop assistant was _.A. hesitantB. casualC. cautiousD. considerate27. What is the main purpose of this passage?A. To describe what a movie nut is like.B. To remind readers to spend more time accompanying family.C. To stress the importance of comp
28、any and understanding.D. To explore the key aspects of current parent-child relationship.C“New and improved.” These words are put in so many marketing campaigns that we tend to accept them as linked. But many new drugs arent an improvement over the best existing drug for a given condition, and the f
29、ast drug-approval processes in recent years have added to the uncertainty about their advantages.A recent report in the British Medical Journal, New Drugs: Where Did We Go Wrong and What Can We Do Better?, analyzed the issue. The authors looked at 216 drugs approved between 2011 and 2017; 152 were n
30、ewly developed, and 64 were existing medicine approved for new uses. Only 25% offered a major advantage over the established treatment, and fully 58% had no confirmed added benefit to reduce symptoms or improve health-related quality of life.This doesnt mean theres no added benefit, lead author Wies
31、eler said. “It just means we have no positive proof. Either we have no studies or have studies not good enough.” Wieseler and her co-authors work for a German institute which evaluates new treatments and advises on whether the countrys health care system should pay a premium (附加费) for them. Such org
32、anizations, known as health technology assessment (HTA) agencies, work a little differently in the US, says Sean Tunis, a researcher in Baltimore: “If payers think a new drug isnt better than an existing drug, these agencies will require that hospitals try the cheaper drug first.”Germanys HTA demand
33、s trials to prove that a new treatment beats the existing standard. This isnt always practical. For one thing, such studies can be expensive and time-consuming, with no guarantee of success. Secondly, it can discourage companies from attempting to develop new alternatives. This is already happening.
34、 Drug developers are increasingly focused on areas where there are no good treatments to compete with, such as rare diseases.This lack of meaningful data to guide patients is a major point of Wieselers paper. With accelerated approval, there are more products approved, with a greater amount of uncer
35、tainty about risks and benefits. But there are other solutions besides drug trials. One idea is to require postmarket studies to track the effectiveness of newly approved drugsa step too often neglected.28. What message does the recent report convey?A. Many new drugs have no improved advantages.B. T
36、he approval processes for new drugs are too fast.C. Improved drugs have advantages over old ones.D. Before 2017 no improvement was made to drugs.29. What will US HTA agencies do when no advantage is found in new drugs?A. Remove government premium on them.B. Get hospitals to use the cheaper drugs.C.
37、Arrange financial support for the patients.D. Put new drugs on further trials and studies.30. Whats the disadvantage of Germanys HTA trial demands?A. Making drug companies think of illegal ways to cut cost.B. Pushing companies to try alternatives for existing drugs.C. Getting patients to depend on t
38、he government for support.D. Holding companies back from improving existing drugs.31. What is the best title for the text?A. The Advantage of Existing DrugsB. Misunderstanding of New and Old DrugsC. A Dilemma with New Drug AlternativesD. Peoples Preference for New or Old DrugsDTheyre still kids, and
39、 although theres a lot that the experts dont yet know about them, one thing they do agree on is that what kids use and expect from their world has changed rapidly. And its all because of technology.To the psychologists, sociologists, and generational and media experts who study them, their digital d
40、evice sets this new group apart, even from their tech-savvy (懂技术的) Millennial elders. They want to be constantly connected and available in a way even their older siblings dont quite get. These differences may appear slight, but they signal an all-encompassing(包罗万象的) sensibility that some say marks
41、the dawning of a new generation.The contrast between Millennials and this younger group was so evident to psychologist Larry Rosen that he has declared the birth of a new generation in a new book, Rewired: Understanding the iGeneration and the Way They Learn, out next month. Rosen says the tech-domi
42、nated life experience of those born since the early 1990s is so different from the Millennials he wrote about in his 2007 book, Me, MySpace and I: Parenting the Net Generation, that they warrant the distinction of a new generation, which he has dubbed the iGeneration.The technology is the easiest wa
43、y to see it, but its also a mind-set, and the mind-set goes with the little i, which Im using to stand for individualized, Rosen says. Everything is defined and individualized to me. My music choices are defined to me. What I watch on TV any instant is defined to me. He says the iGeneration includes
44、 todays teens and middle-schoolers, but its too soon to tell about elementary-school ages and younger.Rosen says the iGeneration believes anything is possible. If they can think of it, somebody probably has or will invent it, he says. They expect innovation.They have high expectations that whatever
45、they want or can use will be able to be tailored to their own needs and wishes and desires.Rosen says portability is key. They are inseparable from their wireless devices, which allow them to text as well as talk, so they can be constantly connected- even in class, where cellphones are supposedly ba
46、nned.Many researchers are trying to determine whether technology somehow causes the brains of young people to be wired differently. They should be distracted and should perform more poorly than they do, Rosen says. But findings show teens survive distractions much better than we would predict by the
47、ir age and their brain development. Because these kids are more immersed and at younger ages, Rosen says, the educational system has to change significantly. The growth curve(曲线) on the use of technology with children is exponential(快速增长的), and we run the risk of being out of step with this generati
48、on as far as how they learn and how they think, Rosen says. We have to give them options because they want their world individualized. 32. Compared with their Millennial elders, the iGeneration kids _.A. communicate with others by high-tech methods continuallyB. prefer to live a virtual life than a
49、real oneC. are equipped with more modern digital techniquesD. know more on technology than their elders33. Why did Larry Rosen name the new generation as iGeneration?A. Because this generation is featured by the use of personal high-tech devices.B. Because this generation stresses an individualized
50、style of life.C. Because it is the author himself who has discovered the new generation.D. Because its a mind-set generation instead of an age-set one.34. Rosens findings suggest that technology _.A. has an obvious effect on the function of iGenerations brain developmentB. has greatly affected the i
51、Generations behaviors and academic performanceC. has no significantly negative effect on iGenerations mental and intellectual developmentD. has caused distraction problems on iGeneration which affect their daily performance35. According to the passage, education has to _.A. adapt its system to the n
52、eed of the new generationB. use more technologies to cater for the iGenerationC. risk its system to certain extent for the iGenerationD. be conducted online for iGenerations individualized need第二节（共5小题；每小题2分，共10分）根据短文内容, 从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。注意：请将E选成AB，F选成AC，G选成AD。Benefits of SportsDo
53、ing sports is a physical, mental and social adventure. Its a great way for children to take a break from academics and release extra energy. It also helps them lead fuller and happier lives as regular sports have proven to improve overall well-being.The physical benefits of doing sports are probably
54、 the most obvious. Regardless of your fitness level when you start playing sports, youll notice an increase in your overall fitness once youre involved. _36_ Basketball players focus on strength training; football players work on speed while track athletes train through longer runs. The training pro
55、cess helps promote physical fitness and performances in competitions._37_ Playing sports contributes to mental health, helping to increase confidence and self-worth. A pat on the back, high-five from a teammate, or handshake after a match really boosts a childs confidence. Words of praise and encour
56、agement from the coach, parents and other players raise the self-worth. _38_ So after a game, its a better idea to ask “Did you enjoy the game?” rather than “Did you win?”Children who participate in sports might also benefit from the social aspect, feeling part of a group, building up accountability
57、 and leadership. _39_ Teamwork involves both being dependable as a teammate and learning to rely on your teammates to achieve a positive outcome. Teamwork breeds accountability and challenges you to be responsible for your actions. Being part of a team gives you an opportunity to be a leader.Discipl
58、ine is another social advantage. Most organized sports require a strict training and practice schedule. As a student-athlete, you need to balance academics and athletics. _40_There is no shortage of reasons to find a sport to get involved in. Are you ready to go? Pick one and get moving!A. Its not j
59、ust your body that benefits from sports.B. Therefore, playing sports is going to make you more fit.C. But remember, a childs self-worth should not be distinguished by victory or loss.D. If you play group sports, youll be part of a team that takes direction from a coach.E. Nearly every sport requires
60、 physical activity and the skills needed to be competitive.F. Among these, learning how to function as part of a team is the most important advantage.G. Only with strict discipline can you be successful both in the classroom and in the sports field.第三部分 完形填空（共 20 小题；每小题 2分，共 40 分）阅读下面短文，掌握其大意，从每题所给的

65、if they feel they are being treated like a number and not an individual.Along with fake news, advertising fraud(诈骗), and data leaks, there have been fake reviews as well. Many sellers are using the platform to _52_ Amazon with positive reviews that arent from genuine buyers, making building trust ev
66、en more difficult. Review sites have been _53_ giving preferential treatment to paid advertisers and consumers are increasingly discerning(有辨别能力的), as a result._54_, review sites are not our only source of peer reviews, with social media providing customer experiences on a second-to-second basis. Wh

In an age of cutting-edge technology, artificial intelligence, and self-service customer care, it
