(warn) about typhoon，the fishermen sailed for the nearest harbour. 2.The teacher didn’t catch Mike cheating in the exam，so he escaped (punish). 3.The problem is far from (settle).We shall continue discussing it at the meeting (hold) tomorrow.;4.The question (discuss) now has something to do with nature. 5.Our neighbour came close to (kill) in a traffic accident the other day.;动词--ing形式包括现在分词和动名词两种形式，因而其被动结构也有这两种形式。从时态上讲，动词--ing形式的被动语态有一般时和完成时两种，即being done和having been done。动名词的被动形式在句中可作主语和宾语；现在分词的被动形式在句中可作补语、定语和状语。;一、结构;二、意义 1.一般时表示一个被动的动作正在进行或与谓语动词所表示的动作同时发生。 She insisted on being given the hardest work. 她坚持被派给最艰苦的工作。 2.完成时表示的动作发生在谓语动词所表示的动作之前。 I appreciated having been given the chance to study abroad two years ago. 我非常感谢两年前获得了去国外学习的机会。;三、功能 1.主语 Being laughed at in public is a terrible experience. 在公共场合被嘲笑是一次非常不愉快的经历。 2.宾语 I forget once being taken to the sea when I was young. 我忘了小时候曾被带到海边。;注意：(1)表示“需要(want，need，require)”的主语通常是物，用动名词的主动式表示被动时，也可改为用不定式的被动式。 This sentence needs improving. ＝This sentence needs to be improved. 这个句子需要改善。 (2)be worth后常跟动名词的主动形式表示被动含义。 If a thing is worth doing，it is worth doing well. 如果一件事情值得做，就值得做好。;(3)动名词被动形式的复合结构 当动名词被动形式的逻辑主语与句子的主语不一致时，要在v.--ing形式之前加上物主代词或名词所有格(整个复合结构不作主语时，可用人称代词宾格代替物主代词，名词普通格代替名词所有格)。其中物主代词(名词所有格)是v.--ing形式逻辑上的主语。 I’m very pleased at you/your having been honoured with a medal.我很高兴你能荣获一枚奖牌??;3.作表语 What made his parents happy was his being admitted to a famous university. 让他父母高兴的是他被一所名牌大学录取了。 4.定语 The meeting being held now is very important. 现在正在召开的会议非常重要。;注意：动词--ing形式的被动形式表示一个被动的动作正在进行；过去分词表示一个被动的动作已经发生；不定式的被动式表示将来的一个被动动作。 a meeting being held now现在正在举行的会议 a meeting held yesterday昨天举行的一次会议 a meeting to be held tomorrow明天将会举行的会议;5.宾补 He often watched the boats being unloaded. 他常常看到轮船卸货。 6.状语 Being asked to give a performance，she couldn’t very well r
