Question

Mother Teresa _______ great contribution to the world peace, _______ she was awarded the Nobel Price in 1979.

A.might have made, because B.must have made, for

C.could have make, since D.should have make, as

Answer

B

【解析】

考查情态动词及原因状语从句。句意：特蕾莎修女对世界和平一定做出了巨大的贡献，因为她在1979年获得了诺贝尔奖。分析句子，情态动词+have done表示对过去的猜测。根据后句的“她获得了1979年诺贝奖”可以推测，特蕾莎修女对世界和平一定做了很多贡献。must have done 表示过去一定做了某事。A. might have made 可能已经做了；C. could have make 本来能够做；D. should have make 本应该做却……。分析句意，ACD皆不符合。另外根据“she was awarded the Nobel Price in 1979.”可知，第二空应填表示“因为”的引导词来引导原因状语从句。综合分析，故选B项。
