Ken Scott kicked of the covers and leapt out of bed at his home in the Rocky Mountain town of Mullan,Idaho.It was 6 a.m.on January 7, 2020, and he was on a mission: He’d just heard on the radio that the nearby Silver Mountain Resort had been blessed with nearly a foot and a half of new snow. As a ski addict who’d worked in the industry for the past 30 years as a ski patroller (滑雪巡逻员)and equipment salesperson, he didn’t want to miss this perfect skiing chance. These conditions are what skiers live for-even experienced and skilled as Scott, who, at 55, still skied 100 days a year.
When Scott reached Silver Mountain’s locker room, he ran into his friend Warren, 58, a former ski instructor who had also been a regular on these slopes for more than two decades.
“Can you believe it?” he said as they changed into their boots. “Sixteen inches! Are you ready?”
For the next hour, the pair skied on various runs under a lightly gloomy sky, making fresh tracks. They were both in a playful mood. Finally, they reached 16-to-1, an expert-level trail, which was now open. It had been closed all season over concerns that skiers might cause an avalanche (雪崩). But that morning, patrollers had cleared loose snow on the peak, reducing the chance of a snowslide.
“What do you think?” asked Warren.
“Let’s go for it!” Scott replied.
When they reached the top of 16-to-1, Warren excitedly looked back at Scott. The huge, toothy grin on his bearded face was what he needed. He pointed his skis downhill and took off. So thrilled were they that they isolated everything around them. Flying on the trail, despite the biting wind, their hearts burnt with passion for this great skiing. Whoomph! A sudden roar from behind nearly deafened them.

3 . 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.”
