問題詳情：

A．As; whose                                                 B．It; whose

C．As; whom                                                 D．It; whom

【回答】

D

【詳解】

考查名詞*從句和定語從句。句意：我們都知道，那位老科學家，過去生活很艱苦，到了八十多歲還在努力工作。第一空it is known to us all that...是個固定句型，意為“眾所周知……”，it在此是形式主語，that引導的從句為真正的主語；第二空為“介詞+關係代詞”引導的非限制*定語從句，先行詞the old scientist指人，作介詞for的賓語，只能用whom，故選D。

知識點：非限制*定語從句

題型：選擇題
