问题 It only takes a ______of a second for the computer to do the calculation which a human will spend days to do.
选项 A、fiction
B、reduction
C、function
D、fraction
答案D
解析 近形近义题。题干中的a_____of a second和days形成对比，后者表示时间长，那么前者便表示时间短，a fraction of a second指“不到一秒钟”，所以答案为[D]fraction“小部分，一点儿，少许”。[A] fiction“小说，虚构的事”；[B]reduction“减少，缩小”；[C]function“功能，运行”。
