细节题
The Earth’s ozone (臭氧) layer is on its way to recovering, thanks to decades of work to get rid of ozone-damaging chemicals, a panel of international experts backed by the United Nations has found.
The ozone layer serves an important function for living things on Earth. This shield in the stratosphere (平流层) protects humans and the environment from harmful levels of the sun’s radiation.
The international community was alarmed after experts discovered a hole in the ozone layer in May 1985. Scientists had previously discovered that chemicals, used in manufacturing certain sprays and used as refrigerants (制冷剂), could destroy ozone. Two years after the discovery of the dreadful state of the ozone layer, international bodies adopted a global agreement called the Montreal Protocol. This established the phaseout (逐步淘汰) of almost 100 man-made chemicals that were tied to the destruction of the all-important ozone.
In the latest report on the progress of the Montreal Protocol, the UN-backed panel confirmed that nearly 99% of banned ozone-eating substances have been phased out. If current policies stay in place, the ozone layer is expected to recover to 1980 values by 2040, the United Nations announced. In some places, it may take longer. Experts said that 1980-level recovery over Antarctica is expected by around 2066 and by 2045 over the Arctic.
The destruction of the ozone layer is not a major cause of climate change. But research is showing that these efforts to save the ozone layer are proving beneficial in the fight against climate change. “Ozone action is a pioneer for climate action,” said World Meteorological Organization Secretary-General Petteri Taalas. “Our success in phasing out ozone-eating chemicals shows us that what can and must be done—as a matter of urgency—to shift away from fossil fuels, reduce greenhouse gases and so limit temperature increase.”
Why did the international community start to protect the ozone layer?
Because the Montreal Protocol was signed.
","Because chemicals could destroy the ozone layer.
","Because a hole in the ozone layer was discovered.
","Because the stratosphere is harmful to human health.
"]细节理解题。根据第三段的 “The international community was alarmed after experts discovered a hole in the ozone layer in May 1985 ... Two years after the discovery of the dreadful state of the ozone layer, international bodies adopted a global agreement called the Montreal Protocol. (1985年5月，专家们在臭氧层发现一个洞后，国际社会感到震惊。在发现臭氧层的可怕状态两年后，国际组织通过了一项全球协议，称为《蒙特利尔议定书》。)” 可知，国际社会开始保护臭氧层是因为专家在臭氧层发现了一个洞。故选C。
Which of the following can NOT help protect the ozone layer?
Using less hair-setting spray.
","Increasing refrigerant production.
","Minimizing the use of cold air-conditioner.
","Phasing out ozone-consuming substances.
"]细节理解题。根据第三段的 “Scientists had previously discovered that chemicals, used in manufacturing certain sprays and used as refrigerants (制冷剂), could destroy ozone. (科学家此前发现，用于制造某些喷雾剂并用作制冷剂的化学物质，可能会破坏臭氧层。)” 可知，用作制冷剂的化学物质对臭氧层有害。由此可知，增加冰箱的产量不能保护臭氧层。故选B。
What’s the main idea of Paragraph 4?
The Montreal Protocol is taking effect.
","The ozone layer will fully recover by 2040.
","The Montreal Protocol needs to be improved.
","The ozone layer protection has a long way to go.
"]段落大意题。根据第四段 “In the latest report on the progress of the Montreal Protocol, the UN-backed panel confirmed that nearly 99% of banned ozone-eating substances have been phased out. If current policies stay in place, the ozone layer is expected to recover to 1980 values by 2040, the United Nations announced. In some places, it may take longer. Experts said that 1980-level recovery over Antarctica is expected by around 2066 and by 2045 over the Arctic. (在关于《蒙特利尔议定书》进展的最新报告中，联合国支持的小组证实，近99%的禁用臭氧消耗物质已被逐步淘汰。联合国宣布，如果目前的政策保持不变，预计到2040年，臭氧层将恢复到1980年的水平。在某些地方，这可能需要更长的时间。专家表示，预计到2066年左右，南极上空将恢复到1980年的水平，到2045年，北极上空将恢复。)” 可知，本段主要介绍保护臭氧层的《蒙特利尔议定书》正在起作用。故选A。
What can be inferred from Petteri Taalas’ words?
Climate protection has led to the ozone protection.
","The destruction of ozone layer didn’t cause climate change.
","It’s an urgency to reduce the use of ozone-eating chemicals.
","Ozone protection guides our future efforts in climate action.
"]推理判断题。根据最后一段的 “‘Ozone action is a pioneer for climate action,’ said World Meteorological Organization Secretary-General Petteri Taalas. (世界气象组织秘书长佩特里·塔拉斯表示：‘臭氧行动是气候行动的先驱。’)” 推知，保护臭氧是我们未来气候行动的指导方针。故选D。
