We all know that we’ll meet all kinds of difficulties in our lives in the future. We should learn to be ________ any challenge!
A．confident enough to take on
B．active enough to take up
C．enough careful to take try on
D．enough patient to try out
答案：A
试题分析：句意：我们都知道，在我们的生活中将来会遇到各种困难。我们应该学会有足够的自信去迎接任何挑战。enough修饰形容词放在形容词的后面。take on 接纳，承担。take up开始从事···。try on 试穿，try out ,试验。根据句意，故选A。 考点：考查enough的用法及动词短语辨析。
