选择题
He is ______as a leader but he hasn’t__________ in teaching.
A．success; many experiences
B．a success; much experience
C．great success; an experience
D．a great success; a lot of experiences
答案
答案：B
抽象名词具体化，表示具有某种特征的人或事物，可用作可数名词。如：She is a success in business but a failure in marriage (她在事业上是个成功者，但在婚姻上是个失败者)；experience作为“经验”解，为不可数名词。
