问题 It is now widely accepted that averting serious climate change is technically ______ and economically affordable.

选项 A、feasible
B、practicable
C、practical
D、pragmatic

答案A

解析 现在普遍认为,避免严重的气候变化是技术上可行、经济上负担得起的。A.feasible“可行的,行得通的”,用来表示实施后可以成功的,例如:Your work plan is feasible,so we can build the bridge immediately.你的工作计划是可行的,所以我们可以马上修建那座桥。B.practicable“能实施的,可行的”,只表示一种可能性,但是实施后的效果不一定理想,例如:Their marriage was so bad that divorce seemed the only practicable solution.他们的婚姻是如此的糟糕,以至于离婚似乎是唯一可行的解决办法。C.practical“实践的,实用的”,指未经过实践检验的事物,如计划、项目等,例如:She felt that most of what she learned in the course Was of no practical use.她感到在课上学到的大部分知识都没有实际用途。D.pragmatic“讲究实际的,务实的”,强调用常识解决实际问题,不追求不切实际的目标,例如:Our approach is essentially pragmatic.我们的方法从本质上来说是务实的。注:根据并列连词and之后“经济上负担得起”,推测前面表示“技术上可行”,这种可行性是大众认可的,选A合适。
