　　【注意】由主动语态变为被动语态的步骤：
　　1．主动语态句子的宾语变为被动语态句子的主语；
　　2．主动语态的谓语动词变为被动语态的谓语形式，即“be＋及物动词的过去分词”。助动词be既保持主动句的时态，又要与被动句的主语在人称和数上保持一致；
　　3．主动语态句子的主语变为介词by的宾语，再把整个介词短语置于谓语动词之后，有时这个短语可以省略。如：

Maybe I will be a scientist and change the world with my discoveries. Maybe I'll become a musician and touch people's hearts with my music. Or perhaps I will be a writer and move people through words.
