[单项选择] Animal tests —More than a cosmetic (化妆品) change
Every time you reach for an eye-drop or reapply a lip salve, you do be so confident that the chemicals they contain are safe to use. But the toxicology (毒物学) tests on which regulators rely to gather this information are largely based on wasteful and often poorly predictive animal experiments. Efforts in Europe are about to change this, and the man charged with bringing toxicology into the twenty-first century is a plain-talking German: Thomas Hartung. Although Hartung acknowledges the immense challenges ahead, he sees this as an opportunity for toxicology "to turn itself at last into a respectable science".
Three years ago, when Hartung became director of the European Centre for the Validation of Alternative Methods (ECVAM) in Ispra, Italy. ECVAM was set up in 1993 to support European Union policy aimed at reducing the number of animals used in regulatory testing.

[不定项选择题]共用题干
第一篇
Arctic Melt
Earth’s North and South Poles are famous for being cold and icy.Last year,however,the amnount of ice
in the Arctic Ocean(北冰洋)fell to a record low.
Normally,ice builds in Arctic waters around the North Pole each winter and shrinks(缩小)during the
summer. But for many years,the amount of ice left by the end of summer has been declining.
Since 1979,each decade has seen an 11.4 percent drop in end?of-summer ice cover. Between 1981 and
2000,ice in the Arctic lost 22 percent of its thickness,becoming I.13 meters thinner.
Last summer,Arctic sea ice reached its thinnest levels yet.By the end of summer 2007,the ice had
shrunk to cover just 4.2 million square kilometers.That's 38 percent less area than the average cover at that
time of year. And it's a very large 23 percent below the previous record low,which was set just 2 years ago.
This continuing trend has made scientists concerned.
There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer(海洋学家)at the
University of Washington at Seattle.Unusually strong winds blew through the Arctic last summer. The winds
pushed much of the ice out of the central Arctic,leaving a large area of thin ice and open water.
Scientists also suspect that fewer clouds cover the Arctic now than in the past.Clearer skies allow more
sunlight to reach the ocean.The extra heat warms both the water and the atmosphere.In parts of the Arctic
Ocean last year,surface temperatures were 3.5℃warmer than average and 1.5℃warmer than the previous
record high.
With both air and water getting warmer,the ice is melting from both above and below. In some parts of
the Beaufort Sea,north of Alaska and western Canada,ice that measured 3.3 meters thick at the beginning
of the summer measured just 50 centimeters by season's end.
The new measurements suggest that melting is far more severe than scientists have seen by just looking
at ice covcrfrom above,says Donald K. Perovich,a geophysicist at the U.S.Army Cold Regions Research
and Engineering Laboratory in Hanover,N.

Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover.
