几道高中英语单选题,详解.

1.你知道,下句是陈述句,是上句的答句.其实省略了“He wanted to know ”.完整句子为"He wanted to know when it was that I could finish writing the report".,你看看,是不是这样的?那就是D了.
2.for__ life was hard in the past是修饰scientist的,是吧?
如果按照你的想法,就是“scientist,for whose life was hard in the past”.
但是你看,在for whose life was hard in the past句子里面,for whose life是不是某种程度上,有点状语从句的作用?既然是状语从句,那把他拿掉,剩下was hard in the past,是不是里面缺少了主语了?就算读起来是不是也很别扭?不管是语法还是语感上说,是不是该加上it?按照你原来的理解的话,完整的整个句子应该是It is known to us all that the old scientist,for whose life it was hard in the past,still works hard in his eighties.
再问： for whose life怎么就状语从句了 为什么就要加it，好晕
再答： It is known to us all that the old scientist,for whose life was hard in the past,still works hard in his eighties。这个是你认为对的句子。我给变形一下： It is known to us that the old scientist,for whose life was hard in the past,still works hard in his eighties。=The old scientist,for whose life was hard in the past,still works hard in his eighties is known to us。经过变形， The old scientist,for whose life was hard in the past,still works hard in his eighties 从句作为了主语，是一个成分齐全的句子，拿出来分析，可以吧？我再将他简化为：scientist,for whose life was hard in the past, works hard。 for whose life was hard in the past,从中拿掉，剩下的是scientist works hard，主谓宾齐全，完整的句子，for whose life was hard in the past,整个一个定语成分（我上面的回答打错了，他是定语作用），修饰科学家的，整个跑龙套的，有没有他都成。是吧？下面可以单独分析for whose life was hard in the past了。这里面几个词之间都是什么关系？for whose life was hard in the past。明显，life was hard in the past是一起的，不可分割的。按你的想法，for whose life是在一起的，剩下的是was hard in the past，那读读有whose的原句之后你觉得was hard in the past 是作什么的？不完整，应该和life一起才完整。那for whose 两个在一起，明显也不对了，就算英语有诸多你理解的不理解的语法，for这个词是介词，后面也是跟代词或者名词，不能跟其他词的，那for whose 算是什么关系？词法上是for的错误用法了，就算上面我说的你不理解，但这里从for的用法上说，也得选whom，因为whom好歹是个代词，怎么着也是可以放在for后面的。
