Question

"Jack ________ yet, otherwise he would have telephoned me."

A. mustn't have arrived
B. shouldn't have arrived
C. can't have arrived
D. need not have arrived

Answer 1

答案C
本题中otherwise为连词，意思是“否则，要不然”。would have telephoned表达虚拟，与实际相反，即“他并没有打电话”。所以空格处can’t have arrived也是虚拟语气，是对现在情形进行语气强烈的否定推测，意为“他不可能到了”。
