问题 The cumulative ______ of human activities on the global environment is becoming increasingly harmful.
选项 A、effect
B、influence
C、impact
D、outcome
答案A
解析 近形近义题。所填词能被cumulative和harmful修饰，effect“结果，效果；影响”强调直接的因果关系，指对一系列事件适用的原则继续在别的场合产生效果或起作用，符合句意，所以[A]为答案。[D]influence“影响”和[C]impact“影响，效果”不能被cumulative修饰；[D]outcome“结局，成果”指最终的结局或结果，由题干中的increasingly可知并非最终结果，所以[D]不合适。
