含有雙賓語的動詞的被動語態：一般把代表人的賓語（間接賓語）變為被動句的主語，而把直接賓語留作被動句的賓語。如果把主動句的直接賓語變為被動句的主語，則間接賓語前需有介詞（一般是to或for）。常接to的動詞有：give, lend, show, pass等；常接for的動詞有：borrow, make, buy等。

帶有復合賓語的動詞的被動語態：主動句中如果有復合賓語（即賓語和賓語補足語），變為被動語態時，將句子的賓語（即復合賓語中的邏輯主語）變為被動句的主語（賓語補足語也轉化成了主語補足語）。在主動語態中，make, let, have, see, watch, hear, feel, notice等使役動詞或感官動詞后常接不帶to的動詞不定式作賓語補足語，但在被動語態中需加上to。
