问题     By now, the headlines about dead whales washing ashore with pounds of plastic in their belly are commonplace. But plastic’s effects on nature doesn’t stop there—it’s also making climate change worse. A new report published this week by the Center for International Environmental Law details the greenhouse gas emissions from each step in the lifecycle of plastics: from fossil fuel extraction, transport and refining to the production of consumer goods, the managing of plastic waste, and the increase of trash in the oceans. The study authors warn that, if demand for plastics continues to rise, the material’s contribution to climate change will grow significantly.
    This year, emissions from plastics will equal the pollution output of nearly 200 coal-fired power plants with a 500-megawatt capacity, the report finds. The authors estimate that emissions from plastic will reach the equivalent of nearly 300 coal plants in 2030 and over 600 in 2050. They speculate that their predictions underestimate the situation, " due to limitations in the availability and accuracy of certain data. "
    The report also warns that expanding current plastic production will make it " impossible" for the world to meet the Paris Climate Accord’s goal of preventing global warming from exceeding 2. 7 degrees Fahrenheit above pre-industrial averages. United Nations scientists predict that warming beyond that point would result in catastrophic climate change.
    " We need to cut emissions by 45 percent by 2030," Carroll Muffett, president of CIEL, told Popular Science. " Plastics are ready to do almost exactly the opposite. " " Once the plastics are released into the environment," Muffett added, "they continue to impact the climate in perpetuity. Unless they are recycled, of which the vast majority are not. "
    Over 90% of plastics are not recycled, according to a major study published in 2017. Most of this waste is landfilled, while 12% is burned. In addition, millions of tons of plastic trash end up in the ocean each year. Despite a growing awareness of the problem, demand for plastics has not decreased. People bought over 300 million tons of new plastic in 2014, a figure that’s expected to more than double by 2030, according to research agency IHS Markit.
    The CIEL report proposes solutions to our plastic crisis, recommending an end to the creation of single-use plastics, such as shopping bags and excessive wrapping for food items. The study authors also recommend putting a stop to the development of new oil, gas, and petrochemical infrastructure, and they state that plastic producers should be held responsible for their role in the problem.
What can we learn from the first paragraph?

选项 A、The impact of plastics on nature is limited.
B、Plastics are to blame for the worse climate change.
C、The demand for plastics has significantly increased.
D、The contribution of plastics to the climate change will grow greatly.

答案B

解析 推理题。根据题干可定位至第一段。A项中的is limited“是有限的”与原文中的doesn’t stop there“不止于此”相悖,故排除;B项Plastics are to blame for the worse climate“气候变得更糟糕归咎于塑料”与原文it’s also making climate change worse“它也使得气候变得更糟糕”相一致,故为正确答案。C项对应第一段最后一句中的demand for plastics continues to rise,但这是原文if“如果”后面假设的内容,并非事实,故排除。同理,选项D项对应该段最后一句中的the material’s contribution to climate change will grow significantly,这是在假设的前提下得到的可能结果,不能当作事实来陈述,故排除。故本题答案为B项。
