一道简单高中英语单选题目，求详细解答

____is known to us all is that the old writer,for ____ life was hard in the past still works very hard in his eighties.
A.What；whom B.As;whom C.It;whose D.What;whose
第一个我知道是主语从句了，帮忙分析一下后面那半个句子，谢谢，一定要详细，包括句子成分，怎么断开，各做什么成分，反正尽量详细。
如果是life was hard for him，那后面的still works very hard in his eighties不就没有主语了吗？

还有，这道题选A......

Answer 1

____is known to us all is that the old writer
填what
从is断开，is前面缺少引导词，is后面缺少主语
双重成分用what

for ____ life was hard in the past still works very hard in his eighties.
whose
life was......in his eighties这里不缺成分
从Was断开，记住任何句子断开都是从谓语开始的！不过这里断开没什么意义
in the past still works very hard in his eighties.
“在过去直到他18岁，"这是个时间状语，所以可以去掉这部分只分析句子的主干,即for life was hard
应该填写whose他的生活
_______________________________________________
晕，不好意思了
总之in the past still works very hard in his eighties这个代表时间的状语是可以抽调的
那个843205785是对的！

Answer 2

这题选D，对吧~
主语从句你已经知道了，那就不啰嗦了。后面，我们再来分析这个从句，the old writer 是主语，for whose life was hard in the psst 又是一从句，这从句是定语从句，修饰the old writer ，然后 still works very hard in his eighties 是谓语成分。
所以说这个句子是，主语从句中套一个定语从句。

Answer 3

A 因为句子中有is，所以前面用what,what代指后面的that从句，而第二个空为非限制性定语从句，原句序应为life was hard for him，此处whom代指这个him,如果填whose,则从句中就没有主语了，故选A
