答案选A
第一个空 it 作形式主语,真正主语the old scientist still works hard in his eighties.
第二个空 由于语境可以判断,for是对于的意思,因此后面用宾格
句意：我们都知道,这位老科学家在条件见过的过去,仍然努力工作到八十几岁
竭诚相助,

what，whatever，who，whoever，whom，whose，which

没有as
for ___ life was hard in the past应该为非限制性定语从句 只是插入
for后面缺宾语
不知道清不清楚雅
收起
A.
1。没有As is 的用法，is 是谓语，前面需要主语
2。for后面需要宾语。 for him life was hard in the past 过去的生活对他来说是艰辛的
whom 是 who 的宾格
