翻过前面的帖子,发现没有人问这个问题。。。。 The rising of costs of data-processing operations at many financial institutions has created a growing opportunity for independent companies to provide these services more efficiently and at lower cost. (A) The rising of costs (B) Rising costs (C) The rising cost (D) Because the rising cost(C) (E) Because of rising costs
答案没有问题,我的问题在 and at lower cost,这里 and at lower cost 在明显是修饰 independent companies to provide these services 这个动作,且和 more efficiently 平行。
即是说:
more efficiently ,adj+adv,more 修饰efficiently ,efficiently 修饰provide 这个动作;
at lower cost,prep+adj+noun,整体修饰provide 这个动作。
即adv 和介词短语对称,两者都用来修饰一个动作。
所以可推出,
and 连接的两部分不一定要形式对称,只要能完成相同功能也可以,当然形式对称更好。
不知道对否。
