aim at doing ✅
楼下key takeaway
aim at doing，因为aim本身就含有目的的意思，aim to do就显得累赘。同理the goal of doing 而不是the goal to do
be aiming to do / be aimed at doing (*be aimed to do* is wrong)
aim at doing 和 aim at sth都可以吧AC 有人能看看是不是patients的问题吗？
doing强调过程，sth强调prevent本身这件事
不是patients的问题，eldly patients 和 the eldly patient 都可以表示一类人
如果用名词prevention的话，整个句子的重心就变了，aim at the prevention 而不是aim at preventing ... (这件事)
而且用名词prevention后面接了of又接了from，容易弱化prevent ... from ... 的意思，这在GMAT考试中，这是不正确的，这种结构通常都没有prevent sth from doing 意思，from更多的是它的本意，来自
举个栗子
This proposal is aimed at the prevention of polution from factories.
This proposal is aimed at preventing factories from polution.

这几天听了RON的课，他说-tion和-ing的区别有几个：第一个是tion代表的是一个general idea，ing更强调这个动作，第二个是tion一般指那种间接(involved)从事而不是直接从事，第三个是tion是impersonal的，是谁做了这个动作根本不重要，常用在就是一个gernal的说法里（比如讲大道理）。这里说 Medicare was enacted，那么这里明确是有一个enact的人的，所以应该用ing。“THE FOCUS IN ON THE ACTUAL PROCESS, NOT THE GENERAL IDEA”

Aim to do 和aim at 都可以，本题先通过Prevent杀掉DE, prevent sth or prevent sb from doing sth；A中aim at不能接名词Prevention，杀掉。BC语意有差别，B是成为一种预防的方法，C是阻止，选C
prevention是impersonal的，不涉及动作方，gerund有主语Involve过程的意思
aim at doing，因为aim本身就含有目的的意思，aim to do就显得累赘。同理the goal of doing 而不是the goal to do
