A.invited B.had been invited C.was inviting D.would be invited

The old scientist said that he ____to visit their country before long.A.invited B.had been invited C.was inviting D.would be invited
答案应该是B.
关键动词是邀请.老科学家说他已被邀请不久将访问他们的国家.
所以是已经邀请了；还没有访问,而是在不久后将访问.
这种题最是阴险和无聊啦.

before long 是不久以后的意思 应用将来时
选D

应该是D
把before long看成long before 了

B
这是个间接引语，引句原本应该是
"I was invited to visit their country before long."
变成间接引语时，因为主句的said是过去时，所以引语时态也要向过去推，即
一般过去的被动语态 ---〉过去完成的被动语态
was--->had been
