1. SVOiOd（主语+动词+间接宾语+直接宾语）
把主动句转换为被动句，常用原句中的Oi做被动句中的S(主语)，有时也可用Od做句子的主语。但有些带双宾语的动词一般只能用Od而不是Oi做被动句的S，如ask, bring, buy, hand, lend, offer, pass, pay, promise, read, sell, show, take, teach, tell, write等。

Tom read me the letter.→The letter was read to me.
不能说

❌I was read the letter.

2. SVOC（主语+动词+宾语+宾补）
把主动句转换为被动句时，原句中的C仍保留在原来的位置上。用于这一结构的动词有call, consider, declare, expect, find, keep, leave, like, make, paint, prefer, think, want。
Everyone calls him Jason. →He is called Jason.
