组合练(十五)　环境保护 Ⅰ.阅读理解 A 语篇类型 主题语境 议论文 人与自然——环境保护之全球变暖 (2023·湖北武汉七校联考)It's hard to imagine a snowstorm in Texas could be caused by the Arctic，right？They're thousands of miles away from each other！But if we take a closer look，scientists are theorizing(从理论上说明) that rapid heating of the Arctic can drive cold air from the North Pole further south，and surprisingly enough，can end up where we'd least expect.Unfortunately any measure of extreme weather leads to high­demand in electricity，which can cause energy infrastructure(基础设施) to burn out.Likely so，this past week，over 4 million people were，and currently are, stuck in freezing weather conditions without electricity in Texas，a well­known warm US state. Who's to blame? What's to blame? Fingers are pointed in multiple directions as to what the root cause is.Judah Cohen, the director of seasonal forecasting at Atmospheric and Environmental Research，explained，“This can't boil down to natural causes.A warming planet is partially to blame, at least, we theorize.But science is behind this historical phenomenon.” When we see a natural disaster involving heat, we usually link it with climate change.Is that where we place the rest of the blame involving Texas? While it seems a bit uncharacteristic，scientists hypothesize(假设) that sudden winter storms are associated with climate change.As the Arctic is “currently one of the fastest­warming regions on the planet”，the rising temperatures may increase the odds of an imbalanced polar vortex(极涡)． As climate continues to warm, it's suggested that this can and will happen more frequently.Natural disasters have proven that we need to become adequately prepared for what Mother Nature with a dash of climate change can do.Systems need to be created with reliable and lasting capabilities that can carry the next unexpected and possibly worse phenomenon. 1．What is the main purpose of the first paragraph? A．To introduce polar­based scientific theories. B．To explore why Texas suffered cold weathe
