问题 选择题

—What do you think of genetically modified food (转基因食品)?

—We all think ______ is careless ______ some scientists to say it is safe before doing any experiment.

A.that, for

B.it, for

C.it, of

D.that, of

答案

C               

             

题目分析: 考查代词与介词。句意:你认为转基因食品如何呢?我们一直认为科学家在做实验之前说这是安全的,这事是很粗心的。考查it be +adj+of sb to do,it做形式主语,真正的主语是后面的不定式,of用来表达某人品质或特性, 所以选C项。
