问几道题 求大家帮忙解答 不胜感激
请大家帮忙解答这样几道语法题
1.    The Baldrick Manufacturing Company has for several years followed a policy aimed at decreasing operating costs and improving the efficiency of its distribution system.
A.    aimed at decreasing operating costs and improving
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 decreasing of operating costs and improving
E.    with the aim to decrease operating costs and to improve
  正确答案是A，我的疑问是，先暂且不管后面的平行结构，为什么是aimed而不是aiming呢？并且，我认为E是没有问题的啊
2.    Despite protests from waste-disposal companies, state health officials have ordered the level of bacteria in seawater at popular beaches to be measured and that the results be published.
正确选项是这样的：that the levels of bacteria in seawater at popular beaches measured and the results 后面是不是少了一个be啊

1. a policy aimed at 和a policy aiming at都是常见的正确用法 无区别

E with the aim of ....

2. 你确定你给出的是正确选项？正确选项应该是这样的：that the levels of bacteria in seawater at popular beaches be measured and the results  第一个be是不能省略的，因为表被动，第二个that 和be同时省略
