Question

That art center is _______ used to be a factory, ______ millions of tractors were produced.

A．where; where

B．what; where

C．what; which

D．where; which

Answer 1

B

试题分析：第一空的连词在表语从句中作主语，故选what；第二空后面连接的是定语从句，它是被动语态，所以不缺主语和宾语，故选where， 所以应选B。
点评：本题难度适中。把几个从句放在一个句子里考查，增加了试题的难度，需要考生能够分析理解句子的结构，熟记连词关系词的句法功能。
