问题 More and more advanced farm machines_____, the agricultural production increase tremendously.
选项 A、using
B、having used
C、having been used
D、to have been used
答案 C
解析 本句的原因状语采用现在分词表示独立主格结构，由于主句和从句的主语不一致，故在作状语的现在分词之前加了其逻辑主语more and more advanced farm machines：从时间上看，产量的提高发生在使用先进的机械之后，所以需要用完成时，而且必须构成被动语态才能够阐述所要表达的意思。
