17、于她，她感到很自然。在现代英语中，更为常见的形式是把先行词it置于句首，作形式主语，而把实际主语的不定式置于谓 语动词之后，尤其是当主语较长，或谓语动词不是连系动词，或谓语动词为被动语态时；而在疑问句和感叹句中则必须用这种形式。It is not easy to remember all these words in an hour.在一个小时内记住所有这些词可不容易。It was expected of him to see the play.他可望去看这出戏。How long did it take you to get there?你们用了多长时间到达那儿？What a joy it w

24、式，作主语补语的不定式可省略to。What he did was(to)help you.他所做的事情是帮助你。All I have to do is(to)wash the dishes.我所要做的一切是洗这些碟子。4.带wh-疑问词的不定式短语作主语短语 Our difficulty is where to find a guide.我们的困难是上哪儿找个向导。,六、作宾语补语 在有些动词后面的复合宾语中，不定式（短语）可以做宾语补足语，宾语为不定式（补语）的逻辑主语。不定式作宾语补语有带to与不带to的两种情况。1.带to的不定式作宾语补语 1）在表示思维活动的动词后；这类动词有：con

31、辑上的动宾关系。It was a game to remember.那是一场令人难忘的球赛。I have nothing to say on this question.在这个问题上，我没有什么话要说。3、有些后面带不定式宾语的动词，其同源名词也可被作后置定语的不定式修饰。His wish to visit China is quite understandable.他访问中国的愿望是完全可以理解的。（名词wish与常后接不定式的动词wish同源）Her decision to be a pianist is final.(decision与常后接不定式的动词decide同源)4、有些后面带不

42、d,from having endured the keenest pain.他的胆识是由于他有过最坏的遭遇，忍受过最强烈的痛苦。七、动名词的被动式 动名词的被动语态有一般式与完成式两种。1、动名词的一般式用于被动语态，如：He narrowly escaped being run over.他差一点被车压着。I have not the least objection to his being shot.我对枪毙他毫不反对。2、动名词完成式用于被动语态。He prided himself on having never been beaten in chess.他为奕棋上从未被击败而自豪。H

43、is arm was not in a sling,and showed no sigh of having been damaged.他的手臂并未用吊带吊起，出没有受到伤的迹象。3、有些动名词在句中具有主动的形式，但含有被动的意义，如：The house needs repairing.房子需要修缮。If a thing is worth doing,it is worth doing well.一件事如值得做，就应把它做好。这类动词有：require,need,want,deserve等。,八、动名词与不定式的比较 1、二者有时无甚区别，只是动名词着重进程，不定式着重结果。如：Seeing

45、n to tell a lie.我不善于说谎。I hate smoking.我讨厌吸烟。I hate to smoke.我不爱抽烟。2)动名词可表一般或抽象的多次性行为，而不定式则往往表具体的一次性的动作，如：Playing with fire is dangerous.玩火危险。（泛指玩火）To play with fire will be dangerous.玩火会发生危险。（指一具体动作）,第三节 分 词分词是动词的三种非限定形式之一，包括现在分词和过去分词两种。一、现在分词与过去分词的区别 现在分词与过去分词的区别主要表现在语态和时间概念上。在语态上，现在分词（除被动式外）表示主动意思

46、，过去分词表示被动意思。在时间上，现在分词表示动作正在进行，过去分词则表示动作已结束。the moving story 动人的故事 the moved audience 受感动的观众 boiling water 沸水 boiled water 开水二、现在分词的用法 1、现在分词作定语时多置于它所修饰的名词前，如：exciting news 振奋人心的消息 annoying children 惹人心烦的孩子 She is a charming child.她是一个招人爱的孩子 He asked an embracing question.他提了一个令人难堪的问题。现在分词亦可置于它所修饰的名词

47、之后，如：There were no soldiers drilling.没有士兵在操练。There is nothing doing.不行！2、现在分词作状语 1）作时间状语 Stepping carelessly off the pavement,he was knocked down by the bus.他不小心离开了人行道，被公共汽车撞倒了。While flying over the channel,the pilot saw what he thought to be meteorite.飞过英吉利海峡时，驾驶员认为他看见了一颗陨星。,2）作原因状语 Living in the c
