五、阅读理解(B篇)(2020四川绵阳中考题改编)
Terrible weather events are harming the planet, and experts warn of even greater results to come.The sea ice loss and the Arctic ice melting(融化) caused by climate change have increased much in the last ten years.So they have pushed down the number of polar bears and seals while polar bears depend on sea ice for hunting seals.
According to the data from the WMO, temperatures on Antarctica(南极洲) hit 18.3℃ in 2020, which is higher than the record of 17.59℃ in March, 2015.
Moreover, temperatures in this area have warmed about 3℃ over the last 50 years. Although such temperatures might be considered pleasant for a picnic or a hiking trip, this is the Antarctica we are talking about. It is home to the most inhospitable environment on the planet because it is supposed to be an extremely cold place. In fact, the average temperature of the continent's central area is －57℃.
Besides, many places experienced the extreme weather last summer. Australia underwent its worst
drought (干旱) after the 1930s, leaving bushfires burning so long and causing many deaths.Meanwhile in Europe, crops in the northwest were suffering the driest weather in the past 80 years. And West Texas in America also went through its worst drought in more than 70 years, while floods hit Eastern and Southern China.
“Climate change is bad for us human beings, which causes direct health problems. I'm afraid there will be more common events like the one that 30，000 to 50，000 persons died in Europe in 2003 due to the heat wave there，” Professor Schwartz said. “It will also cause more air pollution, diseases and lack of clean water and so on.”
