Because humans have an inherent need to 1 uncertainty, according to a recent study in Psychological Science。 The new research reveals that the need to know is strong that people will 2 to satisfy their curiosity even when it is clear the answer will 3 。

In a series of experiments, behavioral scientists at the University of Chicago and the Wisconsin school of Business tested students’ willingness to 4 themselves to unpleasant stimuli in an effort to satisfy curiosity。 For one 5 , each participant was shown a pile of pens that the researcher claimed were from a previous experiment。 The twist? Half of the pens would 6 an electric shock when clicked。Twenty-seven students were told with pens were electrified; another twenty-seven were told only that some were electrified。

The insight that curiosity can drive you to do 14 things is a profound one。Unhealthycuriosity is possible to 15 , however。 In a final experiment, participants who were encouraged to 16 how they would feel after viewing an unpleasant picture were less likely to 17 to see such an image。 These results suggest that imagining the 18 of following through on one’s curiosity ahead of time can help determine 19 it is worth the endeavor。 Thinking about long-term is key to reducing the possible negative effects of curiosity,”Hsee says。

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 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 president 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 geometry by assembling a bicycle。But he’s 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 it’s for kids who can’t make it academically,” he says。On one hand,that viewpoint is a logical product of America’s 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 into bachelor’s degrees for all—and the subtle devaluing of anything less—misses an important point:That’s not the only thing the American economy needs。Yes,a bachelor’s degree opens moredoors。Buteven now,54 percent of the jobs in the country are middle-skill jobs,such as construction and high-skill manufacturing。

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-class jobs, but the workers who need those jobs most aren’t equipped to do them。Koziatek’s Manchester School of Technology High School is trying to fill that gap。Koziatek’s school is a wake-up call。 When education becomes one-size-fits-all,it risks overlooking a’s diversity of gifts。

21。A broken bike chain is mentioned to show students’ lack of。A。academic training B。practical abilityC。pioneering spirit D。mechanical memorization22。There exists the prejudice that vocational education is for kids who。A。have a stereotyped mind B。have no career motivationC。are financially disadvantaged D。are not academically successful23。we can infer from Paragraph 5 that high school graduates。A。used to have more job opportunitiesB。used to have big financial concernsC。are entitled to more educational privilegesD。

are reluctant to work in manufacturing24。The headlong push into bachelors degrees for all。A。helps create a lot of middle-skill jobsB。may narrow the gap in working-class jobsC。indicates the overvaluing of higher educationD。is expected to yield a better-trained workforce25。The author’s attitude toward Koziatek’s school can be described as。A。tolerant B。cautious 2While fossil fuels—coal，oil，gas—still generate roughly 85 percent of the world’s energy supply, it's 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 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 plummetingprices of renewables，especially wind and solar。The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close 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 lead2018考研英语二真题，notably China and Europe，the United States 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 US2018考研英语二真题，reported the US Energy Information Administration。President Trump has underlined fossil fuels—especially coal—as the path to economic growth。In a recent 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 state’s electricity generation—and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers。The question“what happens when the wind doesn’t blow or the sun doesn’t 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 is driven in part by vehicle manufacturers2018考研英语二真题2018考研英语二真题，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 there’s a long way to go，the trend lines for renewables are spiking。The pace of change in energy sources appears to be speeding up—perhaps just in time to have a meaningful effect in slowing climate change。What Washington does—or doesn’t do—to promote alternative energy may mean less and at a time of a global shift in thought。
