Question

________ is known to us all is that the old worker, for _______ life was hard in the past, still works hard in his seventies.

A．As; whom

B．What; whose

C．It; whose

D．What; whom

Answer 1

D

解析試題分析：句意：我們都知道的是對他來說過去的生活很難的那個老工人70幾歲了還在辛苦的工作。What引導一個主語從句，并作從句的主語。第二個空代替先行詞the old worker，并作介詞for的賓語，用whom。如果填whose，定語從句就沒有主語了。選D。
考點：考查名詞性從句和定語從句的引導詞
