Question

15. When you're faced with failure,    you need is to take courage and try again.

A. that       B. all

C. which      D. it

Answer 1

15.   B考查定语从句的关系词。句意：当你面对失败时，你所需要的就是鼓起勇气再试一次。all是主语，主句，all is to take courage and try again,M you need是all的定语从句，省略了关系代词that, that在定语从句作need的宾语，可以省略，故选B项。
