【题目】Scientists have long understood the key role that oceans play in regulating the Earth’s climate. Oceans cover 70 percent of the globe and store a thousand times more heat than the atmosphere does. What’s newer is the understanding of how this key component of our climate system responds to global warming.

A brake on global warming — for now

One of oceans’most important climate functions is absorbing heat and carbon dioxide (CO2), one of the gases that cause global warming. Acting as a heat sponge (海绵), oceans have absorbed huge amounts of heat and CO2 in the last forty years.

Fujita explains that "oceans are saving us from faster climate change — they are a big flywheel that delays rapid overheating of the Earth, putting a brake on the climate system."

"That’s the good news," he adds. "The bad news is that oceans only slow the atmospheric warming. Once oceans come to balance with a greenhouse gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter." But where and how oceans release this accumulated (积累的) heat is uncertain. And as oceans store heat, fragile underwater ecosystems are struggling.

The most recent scientific report from the Intergovernmental Panel on Climate Change (IPCC) also notes with concern that oceans are acidifying because of increased absorption of atmospheric CO2, and thus causing a threat for shell-forming species. Sharp increases in carbon dioxide levels will cause further acidification of oceans.

Currents distributing heat

Another important role oceans play is that of distributor. Oceans deliver heat and life-sustaining nutrients around the globe. Just as blood vessels bring oxygen and nutrients to cells in the human body, oceans’ currents carry oxygen, nutrients and heat throughout the Earth. Oceans distribute 25 percent to 50 percent of the energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern Europe a milder climate than it would normally have so far north. A change to oceans’ circulation (循环) patterns could throw Europe into a colder period, even as the rest of world experiences warmer temperatures.

This passage mainly talks about .

A.the roles of oceans B.global warming

C.ocean currents D.carbon dioxide

【题目】When there are some strangers in front of us, which of them will we trust?

According to a new study in the online PLOS One, people make their decisions to trust others largely based on their faces.Your appearance can do a lot for you, especially if you are in the financial industry.The more trustworthy you look, the more likely people will buy what you’re selling.

Researchers from Britain’s University of Warwick Business School, University College London, and Dartmouth College, US, did a number of experiments.

The research team used computer software to make 40 faces, from the least to the most trustworthy-looking.

The study said that the difference between a trustworthy face and one that isn’t as trustworthy comes from features that look slightly angry or slightly happy, even when the face is at rest.However, a slightly happy face is more likely to be trusted.

Researchers gave participants some money and asked them which face they trusted to invest the money for them.Then researchers gave some good and bad information about the people with these faces, and asked the participants again whom they trusted.

The results showed that even if they got different information, the participants didn’t change their choices.They were still more likely to invest their money with the more trustworthy-looking faces.

Chris Olivola, one of the study’s authors, said in the University of Warwick’s press release: “It seems we are still willing to go with our own instincts about whether we think someone looks like we can trust them.The temptation to judge strangers by their faces is hard to resist.”

Which of the following can be a proper title for this passage?

A.What kind of face do you trust?

B.Who did the experiments?

C.Why do you trust him or her?

D.Why did they do the experiments?
