Question

英文翻译，100分请大家给我讲讲句子中的语法

1）all nodes from which the interest message was first received
2) node from which the interest message was first received
3）The manner in which you discharge a battery directly affects the life-span of the battery.
这几句中的which是怎么用的？为什么which前面会有from和in，求教具体的语法。顺便请各路大神给翻译一下。

Answer 1

1）all nodes from which the interest message was first received
所有结点（均显示）首个接收的利益信息。
2) node from which the interest message was first received
同上。node 前要加一个 a 或 the（一个）
3）The manner in which you discharge a battery directly affects the life-span of the battery.
你给电池释放电容的方式直接影响电池的寿命。

此处 which 从句为名词性的，作介词 from 的宾语。而整个介词短语做后置定语修饰 nodes。which 前加什么介词是根据语义需要而为。
