I know you have eaten all sorts of junk food your mother and I probably _____ you have. A．shouldn’t let B．can’t let C．couldn’t have let D．shouldn’t have let

Answer 1

D

试题分析:考查情态动词用法。根据语境可知此句是对过去事情的推测，排除A、B选项，而couldn’t have done意思是“不可能做过某事”，而shouldn’t have done意思是“本不应该做某事（但是做了）”，所以D选项正确。句意：我知道你已经吃完了各种我和你妈妈本不该让你吃的垃圾食品。
