1.你知道,下句是陳述句,是上句的答句.其實(shí)省略了“He wanted to know ”.完整句子為"He wanted to know when it was that I could finish writing the report".,你看看,是不是這樣的?那就是D了.
2.for__ life was hard in the past是修飾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是不是某種程度上,有點(diǎn)狀語從句的作用?既然是狀語從句,那把他拿掉,剩下was hard in the past,是不是里面缺少了主語了?就算讀起來是不是也很別扭?不管是語法還是語感上說,是不是該加上it?按照你原來的理解的話,完整的整個(gè)句子應(yīng)該是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.for whose life怎么就狀語從句了為什么就要加it，好暈It is known to us all that the old scientist,for whose life was hard in the past,still works hard in his eighties。這個(gè)是你認(rèn)為對(duì)的句子。我給變形一下：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。經(jīng)過變形，The old scientist,for whose life was hard in the past,still works hard in his eighties 從句作為了主語，是一個(gè)成分齊全的句子，拿出來分析，可以吧？我再將他簡(jiǎn)化為：scientist,for whose life was hard in the past, works hard。for whose life was hard in the past,從中拿掉，剩下的是scientistworks hard，主謂賓齊全，完整的句子，for whose life was hard in the past,整個(gè)一個(gè)定語成分（我上面的回答打錯(cuò)了，他是定語作用），修飾科學(xué)家的，整個(gè)跑龍?zhí)椎模袥]有他都成。是吧？下面可以單獨(dú)分析for whose life was hard in the past了。這里面幾個(gè)詞之間都是什么關(guān)系？for whose life was hard in the past。明顯，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，那讀讀有whose的原句之后你覺得was hard in the past 是作什么的？不完整，應(yīng)該和life一起才完整。那for whose 兩個(gè)在一起，明顯也不對(duì)了，就算英語有諸多你理解的不理解的語法，for這個(gè)詞是介詞，后面也是跟代詞或者名詞，不能跟其他詞的，那for whose 算是什么關(guān)系？詞法上是for的錯(cuò)誤用法了，就算上面我說的你不理解，但這里從for的用法上說，也得選whom，因?yàn)閣hom好歹是個(gè)代詞，怎么著也是可以放在for后面的。
