Question

separate journals have now appeared aimed towards 望具体分析apeared aimed~THX!
这句话原句是separate journals have now appeared aimed mainly towards either professional or amateur readership.我知道appear是系动词，我主要的疑问是后面为什么是aimed而不是aiming?

Answer 1

语法：
appear是半系动词
aimed mainly towards either professional or amateur readership
是分词短语 修饰 主语jounals
aim at/towards sth 针对~
有些(独有的,特殊的)杂志主要是针对~
separate jounals have now appeared aimed mainly towards either professional or amateur readership
其实句子结构是这样的
separate jounals（ aimed mainly towards either professional or amateur readership） have now appeared
分词短语过长 ,出现了后置现象
翻译：
现在看起来,这样发展的必然结果是出现针对专业读者和业余读者的不同杂志.
至于后置定语为什么用过去分词 而不用动名词 是因为
be aimed at/towards 为固定短语 以…为目的,以··为针对对象
这里 该杂志是以针对专业读者和业余读者为对象的杂志
eg It is original old policy aimed at foreign capital enterprise two avoid 3 halve
就是原来的老政策,也只是针对外资企业的两免三减半
Hence,a great point to be aimed at is to get the working quality well trained.
因此,要瞄准的大目标就是要练好工作本领.
要是还有什么问题
