请教英语高手 非谓语问题 在线等您的回答~~~

By owing land and other parts of the agricultural business , these new investors are freed from rules aimed at curbing the number of speculative bets that they and other financial investors can make in commodity markets. 请问，这里为什么是aimed，而不用aming?这个非谓语与逻辑主语不应该是主动关系吗？还是为了和主语these new investors 区分开逻辑关系？

Answer 1

这里使用aimed，其实是因为词组be aimed at（旨在，为了；以...为目的）。
与主动被动无太多关联，不要纠结。
这句子可以填补一下成分进去帮助理解：
these new investors are freed from rules (which are) aimed at...
从这里可以看出选用aimed，其实只是因为使用了词组be aimed at。
属于固定搭配，无需纠结~~呵呵~~

Answer 2

首先要全面地了解aim的词性，才可以正确、灵活地运用这个词：
1、aim, n, 略。
2、aim, vi.
to aim at sth; to aim to do sth;
3, aimed, adj.
to be aimed at sth; to be aimed to do sth.
你的句子中的用法属于第3种情形或词性 (adj.)
如果用定语从句来解释就很明显了：
....from rules (which are) aimed at....
如果说，aiming at curbing...也没有问题，属于第2种用法或动词的分词，即：
...from rules (which/that aim at curbing...) aiming at curbing....同样正确。
这如同“面临/面对”
e.g. I have interviewed some workers facing loss of jobs. =...workers who face loss of jobs.
Also, we can say, I have interviewed some workers faced with loss of jobs.=...workers who are faced with loss of jobs.

Answer 3

aimed at做rules的定语，相当于rules （which are）aimed at...定语从句中，which are结构一般是可省略的。 be aimed at doing sth./aim at doing sth.的用法都有，表示旨在...。 be aimed at doing 源于 aim sth. at doing sth. 把... ...指向.... ..，借用... ...实现... ...目的。用which are aiming at也是不太对的，若非要用主动，也用成 which aim at。
