A rare hole has opened up in the ozone layer above the Arctic, in what scientists say is the result of unusually low temperatures in the atmosphere above the north pole.

The hole, which has been (racked from space and the ground over the past few days, has reached record dimensions, but is not expected to pose any danger to humans unless it moves further south. If it extends further south overpopulated areas, such as southern Greenland, people would be at increased risk of sunburn.

However, on current trends the hole is expected to disappear altogether in a few weeks.

Low temperatures in the northern polar regions led to an unusual stable polar vortex（极地漩涡），and the presence of ozone-destroying chemicals such as chlorine（氯）in the atmosphere -- from human activities - caused the hole to form.

“The hole is principally a geophysical curiosity." said Vincent-Henri Peuch. director of the Copernicus Atmosphere Monitoring Service. "We monitored unusual dynamic（动态的）conditions, which drive the process of chemical depletion of ozone. Those dynamics allowed for lower temperatures and a more stable vortex than usual over the Arctic, which then triggered the formation of polar stratospheric（平流层的）clouds and the catalytic（催化的）destruction of ozone."

The hole is not related to the Covid-19 shutdowns that have dramatically cut air pollution and reduced greenhouse gas emissions. It is also too early to say whether the unusually stable Arctic polar vortex conditions are linked with the climate crisis, or part of normal stratospheric weather variability.

Peuch said there were no direct implications for the climate crisis. Temperatures in the region are already increasing, slowing the depletion of ozone, and the hole will start to recover as polar air mixes with ozone-rich air from lower latitudes. The last time similar conditions were observed was in spring 2011.

While a hole over the Arctic is a rare event, the much larger hole in the ozone layer over the Antarctic has been a major cause for concern for more than four decades. The production of ozone-depleting chemicals has been dramatically reduced, under the 1987 Montreal Protocol 蒙特利尔协议），but some sources appear still to be functioning—in 2018. unauthorized emissions were detected from some areas.

New sources of ozone-depleting chemicals were not a factor in the hole observed in the Arctic, said Peuch. "However, this is a reminder that one should not take the Montreal Protocol measures for granted, and that observations from the ground and from satellites are central to avoid a situation where the ozone-destroying chemical level in the stratosphere could increase again.''

1.What is the possible meaning of the underlined word "depletion"?

A.replacement B.consumption

C.increase D.production

2.According to the passage, scientists are concerned about the hole because .

A.it is expected to be a threat to the mankind

B.the new hole is caused by air pollution and greenhouse gas emissions

C.it may encourage further scientific research and environmental awareness

D.it warns us of an oncoming climate crisis

3.What can be learned from the last two paragraphs?

A.The hole over the Arctic shares the same causes as the one over the Antarctic.

B.Human activities are highly responsible for producing ozone-destroying chemicals.

C.The Montreal Protocol has successfully prevented new emissions.

D.Some new illegal emissions are to blame for the hole over the Arctic.

4.The best title for the passage is probably .

A.Record-size Hole Opens in Ozone Layer above the Arctic

B.Actions Urgently Needed for a New Hole in Ozone Layer

C.Environmental Disaster and International Cooperation

D.How a Hole in Ozone Affects our Life on Earth

Jules is now in his sixties, and is one of the many homeless people who live on the streets; he buys a newspaper most days. Today, with his fellow tramps, he reads about yesterday's student demonstrations.

Like many of the tramps who live under the bridges, Jules was not always so poor. A long time ago he was in the Navy, and like many who have been to sea for a long time, he has stayed slim and fit. Despite the strict organization on board ship, he loved his life, and had the opportunity to see many countries. He visited Poland and Russia; in South Africa he realized what he valued in each country was the people he met. He was always astonished and delighted by the ways in which the people he met differed from one country to another. Some day, he hopes, everyone will see the world as he does.

After many happy years in the Navy, he had to retire. The good things in life always come to an end. His mother and father had long since died and he’d lost touch with his other relatives. He became an industrial designer. He was happy, although it wasn’t the same as the sea. He never wanted to get married and have children.

And then there was the period of darkness. He smiles sadly. He shrugs his shoulders and looks at his hands. There are tears in the corners of his eyes. This is something that he cannot bring himself to talk about. ''It all went wrong, '' he whispers.

He was silent for a while, then recovered. He began to talk more loudly. ''Look at me now---it makes me angry. And what about the President? He's been in power for years, and look what he's done for us. Nothing! I am still out on the streets and live the life of a dog.''

1.What can we learn about Jules’ life in the Navy？

A.He only visited three countries.

B.He enjoyed the life on board ship.

C.He was very well paid for the job he did.

D.He liked meeting people from different countries.

2.Why did Jules change his job according to the passage?

A.He wanted to start a family. B.He wanted to be near his relatives.

C.He didn't enjoy the work any more. D.He was too old to stay in the Navy

3.What is Jules's opinion of the President?

A.The President should increase pensions for old people.

B.The President had not had enough time to change things.

C.The President should have done more to help people like him.

D.The President should not allow homeless people to stay on the streets.
