There______ a number of natural mysteries in the world that even make scientists ______
A.exists; confusing
B.are existed; confused
C.exist; confused
D.exist; confusing
试题答案
C
考查固定句型和形容词辨析。There exist...表示“存在、有......”,排除B;exist的单复数要根据后面的名词来定。根据mysteries可知,应该用复数,即原形,排除A;confused“迷惑的”,修饰人;confusing“令人迷惑的”,修饰物。这里修饰的是scientists。故选C。
