Question

 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

Answer 1

B

解析:

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。
