[单选题]Text 1 Giant corporations often claim to be"green,"pointing to programs they've undertaken aimed at being environmentally conscious.But sometimes these efforts don't really amount to much.They can be no more than'igrcenwashing,"a public relations effort that doesn't represent any fundamental shift in thinking.But such a change may actually be going on among several of the world's largest fossil fuel companies,namcs such as ExxonMobil,Shell,and BP.One of the biggest reasons:pressure from the companies'sharcholdcrs.Investors arc asking corporations to make more transparent the effects climate change will have on their businesses,as well as explain what they are doing to reduce their greenhouse gas emissions.While sharcholdcr motivcs are cerlainly aimed at helping in the worldwide fight against global warming,they also represent a practical need to better understand a company's prospects.If the burning of oil and gas is grcaily curtailed as a result of the December 2015 intemational Paris climate agreement,for example,how might that affect the bottom line of a corporation whose chief source of revenue is extracting and selling carbon-emitting oil and gas?Or,conversely,how is a company planning to take advantage of the business opportunities that emerge from a shift away from fossil fuels?Climate Action 100+,for example,is a shareholder action group that is asking corporations to make stronger commitments to meeting the 80 percent cut in carbon emissions proposed by the Paris agreement signed two years ago by nearly 200 nations.Some 225 investment groups who manage more than S26.3 trillion have signed on in support.Last week,intemational energy giant ExxonMobil said it will step up its reporting to shareholders and the public about the impacts climate change will have on its business,including any expected increased risks.The new policy follows a vote by ExxonMobil investors at the company's annual meeting in May that called for a yearly assessment of the effects of climate change on the company.The new position represents a sea change for ExxonMobil,which until the early 2000s had disputed the need to take action on climate change.Around the world national govemments are shaping new policies in an effort to reduce greenhouse gas emissions to a level that will not allow global temperatures to rise more than 2 degrees Celsius.In the U,S.,individual states and cities are pursuing lawsuits against companies that fail to deal responsibly with greenhouse gas emissions,which they contend harm the public.25.The U.S.is quoted to indicate
A.its great achievement in dealing with climate change.
B.greenhouse gas emissions have been under control.
C.countries are striving to cope with climate change.
D.it has rules and laws against greenhouse gas emissions

Passage Three
What do consumers really want That’s a
question market researchers would love to answer. But since people don’t always
say what they think, marketers would need direct access to consumers’ thoughts
to get the truth.
Now, in a way, that is possible. At the "Mind
of the Market" laboratory at Harvard Business School, researchers are looking
inside shoppers’ skulls to develop more effective advertisements and marketing
pitches. Using imaging techniques that measure blood flow to various parts of
the brain, the Harvard team hopes to predict how consumers will react to
particular products and to discover the most effective ways to present
information. Stephen Kosslyn, a professor of psychology at Harvard, and business
school professor Gerald Zaltman, oversee the lab. "The goal is not to manipulate
people’s preferences," says Kosslyn
A. Sometimes people will conceal what they think when being questioned by the market researchers.
B. Stephen Kosslyn and Gerald Zaltman overlook the experiments and criticize the purpose of the study.
C. Harvard researchers have found the corresponding relations between people’s brain and behavior.
D. There are many large organizations endorsing and financing the Harvard group’s further investigations.
