我倒要看看你能否举出现任董事长的一件主要成绩。

I defy you to come up with one major accomplishment of the current president.

《柯林斯英汉双解大词典》

例如，当科罗拉多大学董事会在物色一位新校长时，想要的是一位熟悉州政府事务的领导，因为州政府是该校预算的主要来源。

For example, when the board of the University of Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university's budget.
