Passage A
Washington—The largest ozone （臭氧）hole ever observed has opened up over Antarctica， according to the scientists of the US National Aeronautics and Space Administration （NASA）. They believe it is a sign that ozonedestroying gases produced years ago are just now causing the largest quantities of ozone to disappear①.
This years South Pole ozone hole spreads over about 28.5 million square kilometers， an area three times larger than the landmass of the ed States.
Pictures of the hole have been offered by NASA. The hole appears as a giant blue mass， totally covering Antarctica and stretching to the southern tip of South America.
“The last time the ozone hole was close to this size was in 1998， when it spread over about 27.2 million square kilometers，” NASA said.
Paul Newman， who works with NASAs Total Ozone Mapping Spectrometer （TOMS） instrument on a NASA satellite， said ozone watchers had expected a big hole this year， but not this big②.
The Antarctica ozone hole， first observed in 1985， is caused by the depletion （损耗） of Earthprotecting ozone by humanmade chemicals such as chlorofluorocarbons， known as CFCs.
“Even though these chemicals were not allowed to use from the beginning of 1987， they remain in the atmosphere and will continue to do so for years，” Newman said.
“This years large hole may have been caused by a change in a swirling highlevel air current over Antarctica， which circles the area and contains the zone hole，” Newman said.

Passage B
Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe. Studies by the Council of Europe， of which 21 countries are members， have shown that 45 percent of reptile （爬行动物） species （种类） and 24 percent of butterflies are in danger or dying out.
European concern for wildlife was outlined by Dr. Peter Baum， an expert in the environment and natural resources division of the council， when he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the councils diploma for nature reserves （保护区） of the highest quality， and Dr. Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks， and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right.
“No area could be expected to survive both as a true nature reserve and as a tourist attraction①，” he went on. The shortsighted view that reserved had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future.
“We forget that they are the guarantee （保证） of life systems， on which any builtup area depends，” Dr. Baum went on. “We could manage without most industrial products， but we could not manage without nature②. However， our natural environment areas， which are the original parts of our countryside， have become mere islands in a spoiled and highly polluted land.”
