5.C
C是即使得意思,根据上文,这件事情尚未发生,所以用虚拟语气.D表示虽然 不符合上文中给的提示.
6.D
此题的时态是不难判断的,因为说的是一条规定,所以用一般现在时,而visitor与request之间是动宾关系,即request visitors not to smoke in the museum,究竟是谁要求他们这样做呢?不清楚,也不必知道,因此需要用被动语态.

c
尽管的意思
d
被动语态 be+动词过去式

5、C ‘即使’的意思
6、D ‘被要求’的意思
5、选D的话 是‘虽然’的意思 表示事情已经发生过了，我已经失败了
C的话 是‘即使’，表示我还没有做这件事，提前预测--‘就算我失败了，也会再试一次’
