{01} "You know so much about literature. It"s a pity you failed your degree," Harry said, "You ______ a good teacher." A.would have been B.can have been C.must be D.should have been 解析：语法结构题。本句的难点是：failed your degree是过去发生的行为，该句暗含这样一层意义： If you hadn"t failed your degree you would have been a good teacher．本句的意思是：“约翰，你的文学知识很丰富，没拿到学位可真遗憾，”哈利说，“你本会成为一个好老师。”
本题选A。

本题选A。
