尽管这个介词拼写比较简单，但具体的用法却多的累人。下面有几个链接，你可以参考学习一下。http://web.etiantian.com/staticpages/study/question/question_3138700.htm 这个相对比较精简http://hi.baidu.com/phrstream/blog/item/275df539418207f03b87ce70.html下面说下你的另一个问题：Another problem brought by the advanced technology is the decline in both communication and writing skill of students.这句话我们可以这样理解：A problem is brought by the advanced technology.(被动语态)先进的科技引发了一个问题（一个由先进的科学技术带来的问题）。The problem is decline in both communication and writing skill of students.这个问题就是学生们在交流和写作能力方面的降低。上面的两个句子可以整为含定语从句的主从复合句：Another problem which is brought by the advanced technology is the decline in both communication and writing skill of students.当然也可以变为你在问题中写出的那样的形式。所以在这里介词by的意思为：“被....”“由....”。作用为：表示被动语态里动作的执行者
by是介词，多表方式。后面接名词或动词ing形式，做方式状语
这里的by是介词prep意思是由，被（表示方法或者手段等）这句话的意思是高科技带来的另一个问题就是降低了学生的写作和交流能力。Another problem是该句主语。 brought by the advanced technology 是Another problem 的定语，即高科技带来的另一个问题。个人所见 希望能帮到你
