929.While larger banks can afford to maintain their own data-processing operations, many smaller regional and community banks are finding that the 「cost associated with」 upgrading data-processing equipment and with the development and maintenance of new products and technical staff are prohibitive. (A) cost associated with (B) costs associated with (C) costs arising from (D) cost of (E) costs of 答案是b。解释说因为后面用are。所以cost用复数。 但是cost不能和maintenance并列吗,这样它们一起就一定是复数。cost就不一定是加s了啊 非常感谢啊呀thx
你没有理解这个句子,这个句子说的是many smaller regional and community banks are finding that ,那发现了什么呢,从后面的and可以看出,是发现 costs associated (with) blah blah and (with) the development and maintenance blah blah, 这个maintenance是和development并列的,因为发现了这两样cost,所以cost应用复数,因此后面也应该用复数are
