Grammar 动词-ing形式的被动式 动词-ing形式的被动式, 其构成为 “being+动词的过去分词”, 可在句中作主语, 表语, 宾语, 宾语补足语, 定语和状语, 但不能单独作谓语, 其完成形式为having been done, 多在句中作状语。 如果动词-ing形式的逻辑主语为所表示的动作的承受者，动词-ing形式要用被动语态，动词-ing形式的被动语态有一般式与完成式之分。 1)一般式: Being badly wounded, the whale soon died. George didn’t like being kept waiting. I am not interested in the topic being discussed. He was afraid of being scolded by the teacher. 他害怕被老师责骂。 而且在want, need, deserve, require等动 词后, 尽管表示的是被动含义, 我们却用 动词-ing形式，也可以用不定式的被动形 式来替换。如： The blackboard needs cleaning. = The blackboard needs to be cleaned. 黑板需要擦干净。 The broken window wants repairing. = The broken window wants to be repaired.? 那个破窗户需要修理。 在worth这个形容词后情形也是这样: Her method is worth trying. 她的方法值得试一下。 * Grammar:the passive -ing forms being kept being attacked being abandoned being held being photographed 此外, 动词-ing形式的被动式还可以在句中构成复合宾语。如： You’ll find the topic being discussed everywhere. 你会听到到处都在讨论这个问题。 He often watched the boats being unloaded. 他常常看轮船卸货。 As we approached the village we saw new houses being built. 走近村子时我们看到正在盖新房。 2) 完成式表示动名词的动作发生在谓语动作之前。 He prided himself on having never been beaten in class. 动词-ing形式的被动式在各句中作什么成分? 1.
