注意：被动语态里，人称、数和时态的变化是通过be的变化表现出来的
英语的谓语动词有两种语态
We speak English.
English is spken by us.
宾变主,主变宾,前加by
1. 找宾语 ----即动作的承受者
They make shes in that factry.
2. 判断宾语的单复数 ----即be动词的单复数
3. 判断动词的时态 ----即be动词的时态
4. 修改谓语的时态 ----即原句动词改为过去分词
5. 修改原句的主语 ----即by+ 主语 / 宾语
by them in that factry.
主动语态变被动之歌：被动语态强调宾，be后加上过去分。be要随着主语变，人称时态要弄准。行为对象作主语， 逻辑主语by来引。
