The difficulty of a problem was________ terms of how long it took to complete.
A. defining in
B. defined as
C. defining as
D. defined in
题目解答
答案
D. defined in
解析
此题考察的是固定搭配和语态。"be defined in terms of" 是一个固定搭配，意思是“根据……来定义”。根据句子结构，主语 "The difficulty of a problem" 和动词 "define" 之间是被动关系，因此使用被动语态 "was defined"。选项 D 符合这个搭配和语态。
