11、sSection II Reading ComprehensionPart ADirections:Read the following four texts. Answer the questions below each text by choosing A,B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1It is curious that Stephen Koziatek feels almost as though he has to justify his efforts to give his
12、students a better future.Mr. Koziatek is part of something pioneering. He is a teacher at a New Hampshire high school where learning is not something of books and tests and mechanical memorization, but practical. When did it become accepted wisdom that students should be able to name the 13th presid
13、ent of the United States but be utterly overwhelmed by a broken bike Chain?As Koziatek know, there is learning in just about everything. Nothing is necessarily gained by forcing students to learn geometry at a graffitied desk stuck with generations of discarded chewing gum. They can also learn geome
14、try by assembling a bicycle.But hes also found a kind of insidious prejudice. Working with your hands is seen as almost a mark of inferiority. School in the family of vocational education “have that stereotype.that its for kids who cant make it academically,” he says.On one hand,that viewpoint is a
15、logical product of Americas evolution.Manufacturing is not the economic engine that it once was.The job security that the US economy once offered to high school graduates has largely evaporated. More education is the new principle.We want more for our kids,and rightfully so.But the headlong push int
16、o bachelors degrees for alland the subtle devaluing of anything lessmisses an important point:Thats not the only thing the American economy needs.Yes,a bachelors degree opens moredoors.Buteven now,54 percent of the jobs in the country are middle-skill jobs,such as construction and high-skill manufac
17、turing.But only 44 percent of workers are adequately trained.In other words,at a time when the working class has turned the country on its political head,frustrated that the opportunity that once defined America is vanishing,one obvious solution is staring us in the face.There is a gap in working-cl
18、ass jobs, but the workers who need those jobs most arent equipped to do them.Koziateks Manchester School of Technology High School is trying to fill that gap.Koziateks school is a wake-up call. When education becomes one-size-fits-all,it risks overlooking a nations diversity of gifts.21.A broken bik

22、sil fuelscoal，oil，gasstill generate roughly 85 percent of the worlds energy supply, its clearer than ever that the future belongs to renewable sources such as wind and solar.The move to renewables is picking up momentum around the world：They now account for more than half of new power sources going
23、on line.Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the plummeting prices of renewables，especially wind and solar.The cost of solar panels has dropped by 80 percent and the cost of wind turbines by c
24、lose to one-third in the past eight years.In many parts of the world renewable energy is already a principal energy source.In Scotland，for example，wind turbines provide enough electricity to power 95 percent of homes.While the rest of the world takes the lead，notably China and Europe，the United Stat
25、es is also seeing a remarkable shift.In March，for the first time，wind and solar power accounted for more than 10 percent of the power generated in the US，reported the US Energy Information Administration.President Trump has underlined fossil fuelsespecially coalas the path to economic growth.In a re
26、cent speech in Iowa，he dismissed wind power as an unreliable energy source.But that message did not play well with many in Iowa，where wind turbines dot the fields and provide 36 percent of the states electricity generationand where tech giants like Microsoft are being attracted by the availability o
27、f clean energy to power their data centers.The question“what happens when the wind doesnt blow or the sun doesnt shine?”has provided a quick put-down for skeptics.But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.The advance i
28、s driven in part by vehicle manufacturers，who are placing big bets on battery-powered electric vehicles.Although electric cars are still a rarity on roads now,this massive investment could change the picture rapidly in coming years.While theres a long way to go，the trend lines for renewables are spi

33、e US governmentD.is not competitive enough with regard to its costText 3The power and ambition of the giants of the digital economy is astonishingAmazon has just announced the purchase of the upmarket grocery chain Whole Foods for$13.5bn，but two years ago Facebook paid even more than that to acquire
34、 the WhatsApp messaging service，which doesnt have any physical product at all. What WhatsApp offered Facebook was an intricate and finely detailed web of its usersfriendships and social livesFacebook promised the European commission then that it would not link phone numbers to Facebook identities，bu
35、t it broke the promise almost as soon as the deal went throughEven without knowing what was in the messages，the knowledge of who sent them and to whom was enormously revealing and still could beWhat political journalist，what party whip，would not want to know the makeup of the WhatsApp groups in whic
36、h Theresa Mays enemies are currently plotting?It may be that the value of Whole Foods to Amazon is not so much the 460 shops it owns, but the records of which customers have purchased what.Competition law appears to be the only way to address these imbalances of powerBut it is clumsy. For one thing,
37、 it is very slow compared to the pace of change within the digital economy. By the time a problem has been addressed and remedied it may have vanished in the marketplace, to be replaced by new abuses of powerBut there is a deeper conceptual problem, too. Competition law as presently interpreted deal

39、 the disadvantage of all other media and entertainment companiesThe product theyre selling is data，and we，the users，convert our lives to data for the benefit of the digital giants. Just as some ants farm the bugs called aphids for the honeydew they produce when they feed, so Google farms us for the
40、data that our digital lives yieldAnts keep predatory insects away from where their aphids feed; Gmail keeps the spammers out of our inboxes.It doesnt feel like a human or democratic relationship，even if both sides benefit31.

44、their usersText 4To combat the trap of putting a premium on being busy,Cal Newport,author of Deep work: Rules for Focused Success in a Distracted world,recommends building a habit of “deep work”the ability to focus without distraction.There are a number of approaches to mastering the art of deep wor
45、kbe it lengthy retreats dedicated to a specific task;developing a daily ritual;or taking a “journalistic” approach to seizing moments of deep work when you can throughout the day. Whichever approach,the key is to determine your length of focus time and stick to it.Newport also recommends “deep sched
46、uling” to combat constant interruptions and get more done in less time.“At any given point,I should have deep work scheduled for roughly the next month.Once on the calendar I protect this time like I would a doctors appointment or important meeting”,he writes.Another approach to getting more done in
47、 less time is to rethink how you prioritize your dayin particular how we craft our to-do lists.Tim Harford, author of Messy:The Power of Disorder to Transform Our Lives,points to a study in the early 1980s that divided undergraduates into two groups:some were advised to set out monthly goals and stu
