(2013·湖南长沙四校二模)—Is the letter from your mother?
—Yes.But she ________the letter herself，because she doesn’t even know one word.

A．needn’t have written	B．can’t have written
C．might not have written	D．should not have written

答案

解析

考查情态动词。句意为：——这封信是你母亲写来的吧？——是的。但这封信不可能是她自己写的，因为她一个字也不认识。根据because引导的原因状语从句可知，此处应用can’t have done表示对过去发生的事很有把握的否定推测。
答案：　B
