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：Theirmarriage 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 thatmost 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：Ourapproach 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。
