有人能总结一下吗

It is difficult to prevent crimes against property as (those that are against a person.)
答案是it is to prevent those against a person
如果用to prevent those against a person或 against a person可以吗？这种比较的省略究竟有什么规则？哪位能总结一下？

(Like B) at ML, JL was slowly killed by the mistakes of the medical men who treated him.答案就是这个。如果用as B was可以吗？as和 like能这样替换吗？如果不能，有什么规则可以方便的确认？记得有地方说过，AS强调动作，LIKE强调人，但是有的时候并不容易区分。

OG里对as 和 like的区别有清楚解释。
as  只用作conj.后面跟 句子，意为“如同....”
like 用作prep. 后跟名词/动名词， “像...一样”。在考比较的题目里，几乎都是用like...，并且放在句首，就如同你举的例子。

举例只用such as....，不能用like...。

It is difficult to prevent crimes against property as (those that are against a person.)
as 是连词，后面的内容 要和as前的内容形式一致，也要用句子 it is to prevent those against a person

Choice B, the best answer, correctly and idiomatically uses the preposition like to introduce a comparison that is expressed , in a prepositional phrase. In A, as is used unidiomatically; in comparison, as is properly employed as a conjunction introducing a subordinate clause.

1. like/unlike 用于比较时是prep.后面要接名词
2. like/unlike词组多放在句首，和句子主语构成比较关系，比较对象需要有可比性。
