2.having done: 动名词完成式主要表示发生在谓语
动作之前的动作或状态:

I have no idea of his having done such a thing.

非谓语动词的时态和语态
不定式的时态与语态:
1.不定式的时态与语态的基本形 式(以do为例)
• 不定式一般式的用法:
• ⑴ 表示将来,即表示发生在谓语动作之 后的动作:
• We decided to leave early.
• He asked me to buy him some paper.
【分析】答案选A。句子主语Little Jim与take是被动关系,“被带去看戏” 发生在“想(should love=want)”后,所以用不定式的被动式作宾语。 说明:①动词不定式用主动形式表被动含义的情况: 在作表语或宾补的形容词后用状语时; 作定语修饰have, there be, this / that / these / those be等后面的名词或代词时; 作表语的to blame等。
⑵表示过去未曾实现的愿望:
I should like to have come earlier.
We were to have been married last year.(我们原打算去年结婚。)
大家有疑问的,可以询问和交流
可以互相讨论下,但要小声点
不定式完成进行式的用法: 表示在谓语动作之前一直在进行
如:1. The text is difficult to learn. 这篇课文很难学。(to learn主动表被动) 2. We found the text difficult to learn.我们觉得这篇课文很难学。 (to learn主动表被动) 3. He was to blame for that. 他因此受到了责备。 (作表语的to blame主动表被动) ②need, want和require表示“需要表示”,主语通常是物时,后面除用
studying
1. I don’t know whether you happen ________, (辽宁卷) A. to be heard B. to be hearing C. to hear D. to have heard
【分析】答案选D。hear发生在谓语don’t know之前,用不定式的完成式。 句意是:我不知道你是否已经听说过了,今年九月我要去美国学习。
