问题
More and more advanced farm machines ________, the agricultural production increased tremendously.
选项
A、using
B、having used
C、having been used
D、to have been used
答案
C
解析
由于越来越多地使用先进的农业机械,农业产量大幅度增加。独立主格结构题。该句的主语是the agricultural production,而四个选项里的动词use的逻辑主语不是该句的主语,而是machines,所以这是一个独立主格结构。从时间上看,产量的提高发生在使用先进的机械之后,所以现在分词要用完成式;机器是被使用,所以要用被动,故C项为正确答案。
