[不定项选择题]共用题干
Global Warming
1.Smoke is clouding our view of global warming,protecting the planet from perhaps threequarters of the greenhouse(温室)effect. That might sound like good news,but experts say that as the cover diminishes in coming decades,we are facing a dramatic increase of warming that could be two or even three times as great as official best guesses.
2.This was the dramatic conclusion reached last week at a workshop in Dahlem,Berlin,where top atmospheric scientists got together,including Nobel prize winner Paul Crutzen and Swedish scientist Bert Bolin,former chairman of the UN's Intergovernmental Panel on Climate Change(IPC
C).
3. IPCC scientists have suspected for a decade that aerosols(浮质)of smoke and other partidles from burning rainforest,crop waste and fossil fuels are blocking sunlight and counteracting the warming effect of carbon dioxide(二氧化物)emissions. Until now,they reckoned that aerosols reduced greenhouse warming by perhaps a quarter,cutting increases by 0.2℃.So the 0.6℃of warming over the past century would have been 0.8℃without aerosols.
4.But the Berlin workshop concluded that the real figure is even higher—aerosols may have reduced global warming by as much as three-quarters,cutting increases by 1.8℃.If so,the good news is that aerosols have prevented the world getting almost two degrees warmer than it is now. But the bad news is that the climate system is much more sensitive to greenhouse gases than previously guessed.
5.As those gases are expected to continue accumulating in the atmosphere while aerosols stabilize or fall,that means"dramatic consequences for estimates of future climate change",the scientists agreed in a draft report from the workshop.
Paragraph 4_______
A.Atmospheric Scientists
B.The Calculations Made at the Berlin Workshop
C.The Previous Calculations of the Effect of Aerosols
D.The Scientists' Agreement

[单项选择]The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.
RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that
