请英语高手们来看看这道虚拟句.
Mr.Green________my letter,otherwise he would have replied before now.
A,must have received B,must have failed to receive C,must receive D,must fail to receive
otherwise 的虚拟句一般不是其前的句子用一般陈述语气,后用虚拟语气吗?那应该选D啊,
Mr.Green________my letter,otherwise he would have replied before now.
A,must have received B,must have failed to receive C,must receive D,must fail to receive
otherwise 的虚拟句一般不是其前的句子用一般陈述语气,后用虚拟语气吗?那应该选D啊,
答案是：B.
完整的句子是：Mr.Green must have failed to receive my letter,otherwise he would have replied before now.
实际上,这句话分为两部分,一是前一句,这句和虚拟语气没有关系,是表示说话者带有较为肯定的推测,是推测但较为肯定,所以句中有must来表达这种情形；第二句才是虚拟语气语句,otherwise是用于虚拟语气的付词,意思是“否则”或“如果不是…,那么…”,otherwise he would have replied before now = if he had not received my letter,he would have replied before now.所以虚拟语气是仅仅发生在第二句之内的.
