It"s ten years since the scientist _______on his life"s work of discovering the valuable chemical.
A.made forB.set outC.took offD.turned up

答案
B
解析
此题考短语动词。句子合理的意思应是:自从那位科学家着手/开始去为发现这一有价值的化学物质而工作。至今已经10年。选B项表开始或着手某事,即set out to do sth.或set out on sth.正合理。make for不是固定短语,只能解释为“为……而做”,take off当“脱下(衣物)、从……取下……、(飞机)起飞”等解,turn up意为“出席、露面”,这三项均不合题意。
举一反三
