　　We were asked to discuss the problem at once. The problem was asked to be discussed at once. 这个问题被要求立刻讨论。(双重被动) 3．下列句子变成被动语态时，要用with，不用by Smoke filled the meeting room. ⇒The meeting room was filled with smoke.

　　会议室满是烟。 A cloth covered the table. ⇒The table was covered with a cloth. 桌上盖着一块布。 4．不能变为被动语态的结构 (1)受动词的限制 ①表示状态的及物动词，只能用于主动语态。某些表示状态的及物动词，如have, own, cost, lack, want (缺乏), become, fit (适合), resemble, fail, last, flee, benefit, hold等作谓语时，不能变为被动句。 She resembles her mother. 她像她妈妈。 He lacks selfconfidence. 他缺乏自信。 This hall can hold 2,000 people. 这个大厅能容纳两千人。 ②当及物动词have表示“吃饭”、“患病”、“明白”、“知道”等意思时，没有被动语态形式。 Would you have a cup of tea? 你要喝杯茶吗？ ③当动词get，take表示“懂得”、“知道”，owe表示“欠”，cost表示“使失去(生命、健康等)”的意思时，动词没有相应的被动语态。 Do you get me? 你明白我的意思吗？ How do you take this passage? 这段话你怎么理解？ I owe 50 pounds to you. 我欠你50英镑。 (2)受宾语的限制 ①当宾语是相互代词、反身代词或具有类似相互代词的关系时，动词不能用于被动语态。 They simply cannot contain themselves for joy. 他们简直无法抑制内心的喜悦。 For years the two sisters looked after one another. 多年来两姐妹互相照顾。 ②当宾语前带有主语的形容词性物主代词时，谓语动词通常不能转换为被动语态。 I could not believe my eyes when I saw him still alive.
