参考答案和解析
正确答案： B
解析：
文章第一段第二句指出，“these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through”，所以此处二氧化碳的作用是允许可见光波长的辐射穿过大气层，而不是将其“吸收”，因此A项不符合文章描述，符合题目要求；选项B、C在第二句的后半句有所体现，选项D在第一段的倒数第三句可以找到对应。

    录音中指出随着碳排放量的增加，空气中二氧化碳的含量从1750年以来已经增加了31%，自然通常可以把大部分碳排放吸收到海洋和森林中去，从而减少空气中碳的积累，因此题干正确。
    【录音原文】
    As a result of the steady rise in carbon emissions, the amount of carbon dioxide in the atmosphere has increased by 31% since l750—a rate unprecedented in the past 20, 000 years. Nature usually absorbs a large portion of these emissions in oceans and forests, known as “carbon sinks”, thereby slowing the rate of accumulation in the atmosphere. However, recent trends suggest that carbon emissions are outpacing absorption.
