Question

 The country life he was used to ______ greatly since 1992.

    A. change                               B. has changed     

C. changing                             D. have changed

Answer

 B

【详解】本题考查的是对句子结构的理解。考生易误选A或C , 误认为be used to doing 或be used to do。而此题中he was used to是个定语从句，修饰the country life，前边省掉了that. be used to 的宾语为 the country life,我们选择的应该是主句的谓语动词。因主语为the country life ，因此谓语动词应为单数，应选用has changed。
