单选题
If people do not tell ______ for an electronic computer to do, it will
accomplish nothing. This is the reason why electronic computers will never be
able to replace man.
A. that
B. what
C. how
D. when
【正确答案】
B
【答案解析】what for an electronic computer to do作tell的宾语。这是一个带疑问词的不定式作宾语,其中for an electronic computer作不定式to do的逻辑主语。题句意为:“如果人们不指示电子计算机该做什么,它就将什么也不能干。这就是电子计算机永远也不能代替人类的原因。”
