　　一、動作的執(zhí)行者無需指出或不明確時

　　2. 不及物動詞(或相當(dāng)于一個不及物動詞的短語動詞)和表示狀態(tài)的動詞(或短語動詞)無被動態(tài)形式， 如happen， rise， occur， take place， break out等; 以及l(fā)ack， fit， suit， equal， become， resemble， befall， consist of，look like等。

　　The story took place in 1949.

　　3. 將主動態(tài)形式改為被動態(tài)形式時如遇到動詞后跟雙賓語的情況， 我們只能將其中之一變成主語， 另一個保持不變。當(dāng)直接賓語變成主語時， 保持在原位的間接賓語前需加介詞to。
