Question

______ is known to us all that the old scientist, for ___ life was hard in the past, still works ha

______ is known to us all that the old scientist, for ___ life was hard in the past, still works hard in his eighties.
A.It, whom
B.As, whom
C.As,whose
D.What, whom

为什么不选C？
是不是如果第二空我填whose，就不要for，变成定语从句了？

Answer 1

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，望采纳！！！

Answer 2

答案选D吗
______ is known to us all that the old scientist为主语从句
且主语从句缺主语 名词性从句中的连接词有三类
that。 whether。if（不充当从句中的任何成分）
what，whatever，who，whoever，whom，whose，which
when，where，how，why
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

Answer 3

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
