7 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.

As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).

With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.

The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.

“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.

“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

9 . At eleven, I decided to learn to swim. There was a pool at the YMCA offering exactly the opportunity. My mother continually warned against it, and kept fresh in my mind the details of each drowning in the river. But the YMCA pool was safe.

I had a childhood fear of water. This started when I was three years old and my father took me to the beach.The huge waves knocked me down and swept over me.

The pool was quiet. I was afraid of going in all alone, so I sat on one side of the pool to wait for others. Then came a big boy. He yelled, “Hi, how’d you like to be ducked?” With that he picked me up and threw me into the deep end.I landed in a sitting position, and swallowed water. But I was not frightened out of my wits—when my feet hit the bottom, I would make a big jump to come out of the surface. It seemed a long way down. I gathered all my strength when I landed and made what I thought was a great spring upwards. Then I opened my eyes and saw nothing but water. I tried to yell but no sound came out. I went down, down, endlessly.

When I came to consciousness, I found myself lying on the bed in the hospital.

I never went back to the pool. I avoided water whenever I could. This misadventure stayed with me as the years rolled by.It deprived(剥夺) me of the joy of boating and swimming. Finally, I decided to get an instructor. Piece by piece, he built a swimmer. Several months later, the instructor was finished, but I was not .Sometimes the terror would return. 

This went on until July. I swam across the Lake Went worth.Only once did the terror return. When I was in the middle of the lake, I put my face under and saw nothing but bottomless water. I laughed and said, “Well, Mr Terror, what do you think you can do to me?” I had conquered my fear of water.

10 . In January, 2021, the ice-making work on the ”Ice Ribbon“, a landmark venue for the Beijing Winter Olympics, was completed.

In the Winter Olympics, where races can be won or lost by a small time gap, tiny imperfections in the ice can make all the differences. ”It’s not just a hunk of ice like you’d normally think of, like ice cubes sitting in your freezer,“ told Kenneth Golden, a U. S. mathematician who studies the structures of ice. ”It’s a much more fascinating and complex substance than people would normally think.“

The first step for building any ice rink is to purify the water to remove dissolved solids like salts and minerals. Such impurities don’t fit in the regular hexagonal(六边形的)structure of ice that forms as water freezes. The purer the water, the more consistent the ice surface.

In addition to the need for excellence in the raw materials of ice-making, technology is also very important, As one of the most advanced technologies for winter sports venues, a carbon dioxide cooling technology has been applied on a large scale for the Beijing Winter Olympic Games. CO₂ , is not new when it comes to ice-making. However, it has been gradually replaced by the man-made refrigerant, like Freon.

With increasing attention toward climate change, the old refrigerant has come into use again. As an element of the atmosphere, CO₂, doesn’t damage the ozone layer. Although CO₂ is a greenhouse gas, its greenhouse effect is much lower than that of other synthetic refrigerants. The Winter Olympics venues adopted CO₂ instead of Freon as a refrigerant in ice-making, which will reduce carbon dioxide emissions greatly.

”We believe these technological innovations will bring Beijing 2022 to spectators all over the world in a more impressive way.“ told Gao Bo from the Media Operations Department of the Beijing Organizing Committee for the 2022 Olympic and Paralympic Winter Games.

1. What is the result of impurities in water for ice-making?

A．The water isn’t able to freeze completely.

B．The quality of the ice will be affected.

C．The ice surface will be more consistent.

D．It’s likely for athletes to fall on the ice.

2. Why has CO₂ cooling technology been applied for the Winter Olympic Games?

A．It’s the most advanced technology for ice-making.

B．CO2 is more efficient than other refrigerants.

C．CO2 is more environmentally friendly than Freon.

D．CO2 has already existed in the atmosphere.

3. What is Gao Bo’s attitude to CO₂ being applied to ice-making?

A．Unclear.

B．Opposed.

C．Doubtful.

D．Favorable.

4. Which of the following is a suitable title for the text?
