求by的用法!
RT..(别从字典生硬地抄上来!)还有
Another problem brought by the advanced technology is the decline in both communication and writing skill of students .
这里为什么用BY啊
这里by的意思是什么?
有什么作用?
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,
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
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
