The boss ______ the worker how to do it, or the accident couldn’t have happened.
A.can’t have toldB.ought to tellC.could have toldD.mustn’t have told
A

试题分析:意为:当时老板不可能告诉工人如何做这件事(是对过去的推测),否则这个事故不可能发生。
在英语中,我们对过去的推测,常使用情态动词(not)+have done 结构,故选 A
点评:情态动词对中国学生来讲是一个难点,而情态动词+have done(表对过去的一种推测)更是一个难点和重点,学生要注意区别。
