Instead,the best strategy is to use the agent as a kind oftip service to keep abreast of jobs in a particular database; when youget E-mail, consider it a reminder to check the database again.
分析是把to keepabreast of jobs in a particular database当做不定式做目的状语来讲解，我想说把它当做tip service 的定语讲解可以嘛
还有类似的状语从句问题，如：
Hesearched it with no success but was attracted bythe site‘s “personal search agent”.
Bythe site‘s “personal search agent”又是什么状语成分呢
学生愚钝，期望老师予以解答！

——网友跟分析的分歧在于，不定式 to keep abreast of jobs in a particular database 是修饰动词 use 的目的状语，还是修饰名词 service 的定语。这要看它的逻辑主语是哪个。假如与 use 的逻辑主语相同，则是目的状语；假如逻辑主语是 service ，就是定语。我感觉，分析的剖析愈加合理。
He searched it with no success but was attracted by the site‘s “personal search agent”.
——这是被动语态，by 引出动作 attract 的施事者，所以，介词短语作施事状语。
纠正网友的错误术语，两个句子中没有 “状语从句” 的说法。
