[单选题]Text 2 Tropical rain pounds on the roof of a cavernous warehouse near Jakarta,Indonesia's capital.Inside,youngsters in orange T-shirts haul around clothes,luggage and electrical goods for Lazada,an ecommerce finn,which has just moved in.The 12,000 square metre space is three times the size of the old one,but it already looks full.Three years ago Lazada's entire stock filled a storeroom the size of a studio flat,recalls Magnus Ekbom,its twenty-something boss in Indonesia.Internet shopping accounts for less than l%of all purchases in South-East Asia-a region twice as populous as America,where the proporlion is nearly 10%.But surging smartphone use and a broadening middle class mean the market is set to multiply:perhaps five fold by 2018,reckons Frost&Sullivan,a consulting firm.Since it launched in 2012 Lazada has laid claim to six South-East Asian countries,largely unchallenged by e-commerce giants such as Amazon of the United States,Alibaba of China and Rakuten of Japan.It may soon have to fight them for its tenitory.Lazada was created by Rocket Internet,a Berlin-based investor that helps out startups designed to dominate emerging markets.Rocket still holds a 24%stake,though Lazada has now raised more than$600m from inveslors including Tesco,a Bntish grocer,and Temasek,a Singaporean sover-eign-wealth fund.These deals appear to value it at about$1.3 billion,which could well make it South-East Asia's dearesl technology firm.Like other Rocket companies,Lazada is run by a group of young European emigranLs,plucked from finance and consuhing.It seems ready to stomach years oflosses.In the first half of 2014-Lhe only recent period for which results are available-it lost$50m before interest and tax,on revenues of$60m.Again like other Rocket comparues,its critics say it is just a copycat,in this case a mere clone of Amazon.Lazada's bosses say such charges underestimate the sophistication and ambition required to succeed in places such as Thailand,Indonesia,the Philippines and Vietnam.Online marketing is trickier there than in America or Europe,because locals use a much wider variety of search and social-media sites.The region's diversity means constant adjustment of online portals to suit local languages and cultures.It also means batding a hotch potch of customs rules.
Which of the following is true about Rocket Internet?
A.It aims at dominating intemational markets.
B.It invests on new firms with promising future.
C.Its market value is the highest in Southeast Asia.
D.It helps startups to evaluate the emerging markets.

"Usually when we walk through the rain forest we hear a soft sound from all the moist leaves and organic debris On the forest floor , " says ecologist Daniel Nepstad. "Now we increasingly get rustle and crunch. That's the sound of a dying forest. "
Predictions of the collapse of the tropical rain forests have been around for years. Yet until recently the worst forecasts were almost exclusively linked to direct human activity, such as clear-cutting and burning for pastures or farms. Left alone, it was assumed, the world's rain forests would not only flourish but might even rescue us from disaster by absorbing the excess carbon dioxide and other planet-warming greenhouse gases.Now it turns out that may be wishful thinking. Some scientists believe that the rise in carbon levels means that the Amazon and other rain forests in Asia and Africa may go from being assets in the battle against rising temperatures to liabilities. Amazon plants, for instance, hold more than 100 billion metric tons of carbon, equal to 15 years Of tailpipe and chimney emissions. If the collapse of the rain forests speeds up dramatically, it could eventually release 3 .5-5 billion metric tons Of carbon into the atmosphere each year—making forests the leading source Of greenhouse, gases.
Uncommonly severe droughts brought on by global climate changes have led to forest -eating wildfires from Australia to Indonesia , but nowhere more acutely than in the Amazon. Some experts say that the rain forest is already at the brink of collapse.
Extreme weather and reckless development are plotting against the rain forest in ways that scientists have never seen. Trees need more water as temperatures rise, but the prolonged droughts have robbed them of moisture, making whole forests easily cleared of trees and turned into farmland. The Nino picture worsens with each round of EI Nino,the unusually warm currents in the pacific Ocean that drive up temperatures and invariably presage droughts and fires in the rain forest. Runaway fires pour even more carbon into the air, which increases temperatures, starting the whole vicious cycle all over again.
More than paradise lost, a perishing rain forest could trigger a domino effect—sending winds and rains kilometers off course and loading the skies with even greater levels of greenhouse gases—that will felt far beyond the Amazon basin. In a sense, we are already getting a glimpse of what's to come. Each burning season in the Amazon, fires deliberately set by frontier settlers and developers hurl up almost half a billion metric tons of carbon a year, placing Brazil among the top five contributors to greenhouse gases in the world.

[单选题]Text 4 As the nation experiences one of the worst flu seasons in years,thousands of Americans have already died from influenza,according to the U.S.Centers for Disease Control and Prevention.Though the season peaked in February,the CDC recently warned that we should prepare for a second wave of cases to hit before we emerge from the season entirely.Now,it appears more than 50,000 could die from the flu before the season ends.Perhaps most troubling is that this year marks a century since the deadliest viral outbreak in human history,which claimed the lives of 670,000 American men,women and children and as many as 50 to 100 million people worldwide.Among the lessons medical researchers gleaned from the catastrophic event is the critical importance of getting vaccinated.It's a lesson that much of the public continues to ignore,even as our scientific understanding of communicable diseases continues to grow.-The strain in tlus flu season,H3N2,is particularly nasty.It's similar to the HINl strain that set off the 1918 influenza pandemic,and it has resulted in high rates of death,particularly among the elderly.Researchers have struggled to create effective vaccines for the H3N2 strain;this year's flu vaccine is only about 36 percent effective at protecting against the virus,compared to an average of 45 percent over the past seven years.Nonetheless,it does provide some protection,and the unvaccinated are hit much harder without it.Earlier this year,a healthy young man from Pittsburgh did not get vaccinated and died soon afier getting the flu.While low vaccine efficacy means that those who get vaccinated can still contract the flu,it remains common sense and good civic behavior to get vaccinated.As a result of herd immunity,even low efficacy vaccines are enough to curb a pandemic from happening if vaccination rates are high.Flu vaccines did not exist during the pandemic of 1918,which is why it was so deadly.Yet year after year few Americans bother to get vaccinated.In economic terms,the herd immunity benefits of vaccination are a"public good."If I am vaccinated,I cannot exclude anyone from the herd immunity that I now offer.Similarly,someone enjoying my herd immunity does not diminish someone else's ability to enjoy my herd immunity.What typically happens when a public good like the flu vaccine is available is that many,perhaps most,people underinvest.They free ride off other people who get the vaccine.If too many people opt out of vaccination,communities become wlnerable to flu epidemics.According to the CDC,only 38 percent of the population chose to get vaccinated as ofNovember 2017.Low rates ofvaccination are particularly dangerous for children and the elderly,who are especially susceptible to influenza.As individuals,we have veU little control over the strain of the flu that emerges in a given year,or the efficacy of a vaccine,but we do have complete control over whether we get vaccinated.The public's response to a bad fiu outbreak or to low vaccine efficacy should be an increase in flu vaccinations,not a decrease.39.The author implies in the last paragraph that faced with a bad flu outbreak,
A.the public should try to enhance the efficacy of a vaccine.
B.effective vaccines should be used to control over it.
C.the public should make a quicker response to it.
D.emphasis should be laid more on vaccination than a vaccine efficacy.
[单选题]Text 2 A deal is a deal-except,apparently,when Entergy is involved.The company,a major energy supplier in New England,provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the strict nuclear regulations.Instead,the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court,as part of a desperate effort to keep its Vermont Yankee nuclear power plant running.It’s a stunning move.The conflict has been surfacing since 2002,when the corporation bought Vermont’s only nuclear power plant,an aging reactor in Vernon.As a condition of receiving state approval for the sale,the company agreed to seek permission from state regulators to operate past 2012.In 2006,the state went a step further,requiring that any extension of the plant’s license be subject to Vermont legislature’s approval.Then,too,the company went along.Either Entergy never really intended to live by those commitments,or it simply didn’t foresee what would happen next.A string of accidents,including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage,raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe.Enraged by Entergy’s behavior,the Vermont Senate voted 26 to 4 last year against allowing an extension.Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation,and that only the federal government has regulatory power over nuclear issues.The legal issues in the case are obscure:whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power,legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend.Certainly,there are valid concerns about the patchwork regulations that could result if every state sets its own rules.But had Entergy kept its word,that debate would be beside the point.The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state.But there should be consequences.Permission to run a nuclear plant is a poblic trust.Entergy runs 11 other reactors in the United States,including Pilgrim Nuclear station in Plymouth.Pledging to run Pilgrim safely,the company has applied for federal permission to keep it open for another 20 years.But as the Nuclear Regulatory Commission（NR
C）reviews the company’s application,it should keep it mind what promises from Entergy are worth.30.It can be inferred from the last paragraph that
A.Entergy’s business elsewhere might be affected.
B.the authority of the NRC will be defied.
C.Entergy will withdraw its Plymouth application.
D.Vermont’s reputation might be damaged.
