  • 现在分词的被动式

现在分词的被动式概念:

现在分词的被动式表示它的逻辑主语是现在分词动作的承受者。


两种现在分词的被动式:

现在分词的被动式表示它的逻辑主语是现在分词动作的承受者。根据现在分词动作发生的时间,现在分词的被动式有一般被动式(being done)和完成被动式(having been done)。
如:The question being discussed is very important. 正在被讨论的问题很重要。
        Having been criticized by the teacher, he gave up smoking. 被老师批评以后,他把烟戒了。
注意:在need, want, require, beworth等动词(短语)后,作宾语的现在分词常用主动形式来表示被动含义。
如:Your shoes need cleaning.=Your shoes need to be cleaned. 你的鞋需要清洗一下了。
         This book is well worth reading. 这本书很值得一看。


现在分词被动式的用法:

当要表示一个被动动作时,现在分词就用被动形式。现在分词的一般式和完成式均有被动式形式:
(1)现在分词一般式的被动式。
主要表示现在正在进行的动作,也可表示与谓语动作同时发生的动作:
如:Who is the woman being operated on? 正在动手术的女人是谁? 
        I saw him being taken away by the police. 我看见他被警察带走。
【注】有时现在分词一般式的被动式所表示的动作也可发生在谓语动作之前(此时的现在分词通常用于表示原因,且多为状态动词):
如:Not having a car, he finds it difficult to get around. 由于没车,她感到行动很困难。
(2)现在分词完成式的被动式。
主要表示发生在谓语动词之前且已经完成的动作:
如:The subject having been opened, he had to go on with it. 话题已经开始了,他不得不谈下去。
        Having been written in haste, the book has many mistakes. 这书因写得仓促,所以错误不少。
比较:Being soill, she can't go to school. 由于病得那么严重,她不能去上学。
            Having been ill for a long time he needed time to recover. 由于病了很长时间,他需要一段恢复的时间。
