Keep up good state of mind even if you _____ fail plenty of times.

A．must

B．will

C．can

D．should

答案

解析

考查should的又一用法，should用在if或even if引导的表示条件的从句中，表示一件事听起来可能性很小，但也不是完全没有可能，相当于“万一”的意思，从句谓语由should加动词原形构成，主句不一定用虚拟语气，如：

Please ring me up if you should change your mind. 万一你改变主意，请让给我打个电话。

Should I (If I should) be free tomorrow, I will come. 万一我明天有时间，我就来。
