关于aim地用法—OG11 紫皮25题
25.The Baldrick Manufaturing Company has for several years followed a policy aimed at decreasing operating costs and improving the efficiency of its distribution system.
正确选项是A。
B. aimed at the decreasing of operating costs and to improve
C. aiming at the decreasing of operating costs and improving
D. the aim of which is the decreasig of operating costs and improving
E. with the ai of operating costs ad to improve
这里我比较疑惑为什么要用aimed at, 而不用aiming at(抛开选项的其他错误),在网上查了一下,aim 还可以用于aim to , aim for...
所以我想知道的是这几者分别是什么意思,在什么情况下用哪个,何时主动何时被动。希望能有人解答。谢谢! |
