动名词
虚拟语气

动名词概念：

动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语，也能被副词修饰，动名词有时态和语态的变化。

现在分词和动名词用法比较：

动词的-ing形式包括现在分词和动名词两种形式。他们的句法功能如下：
动词的-ing形式如果作句子的主语或者宾语时，应该是动名词形式；如果作补语或者状语时，应该是现在分词形式。那么作表语或者定语的动名词和现在分词又该怎样区分呢？
1、动名词与现在分词作表语时的比较：
（1）动名词作表语说明主语的内容，回答what的问题；现在分词作表语相当于形容词作表语，说明主语的性质、特征等，回答how的问题。
如：One of the best exercises is swimming. 游泳是最好的运动项目之一。
        What pleases him most is bathing in the sea. 最使他高兴的事是在海中沐浴。
        The situation both at home and abroad is very in-spiring. 国内外的形势都很鼓舞人心。
        The color is pleasing to the eye. 颜色悦目。
（2）动名词作表语，表语和主语几乎处于同等地位，可以互换位置，其句意不变；现在分词作表语，表语和主语则不能互换位置。
如：Our work is serving the people.
      （＝Serving the people is our work.）我们的工作是为人民服务。
        The news was disappointing. 那消息令人失望。
（3）作表语的现在分词前可以用very，quite，rather，greatly等副词修饰，而动名词则不可以。
如：What he said was very encouraging. 他的话很鼓舞人心。
        Our goal is realizing the four modernizations in the near future. 我们的目标是在不久的将来实现四个现代化。
（4）现在分词与形容词一样可以和more，the most构成形容词的比较级和最高级，而动名词则不可以。
如：The story is the most fascinating. 那个故事最迷人。
（5）作表语用的现在分词除了和be连用以外，还可以和其它的系动词连用；而作表语的动名词则通常只能和be连用。
如：His speech seems inspiring．他的演讲似乎很鼓舞人心。
        His interest is writing for the news papers. 他的爱好是给报社写文章。
（6）有些用作表语的现在分词已经形容词化了。常见的有：exciting，moving，inspiring，missing，interesting，disappointing等。
2、动名词与现在分词作定语时的比较：
（1）动名词作定语时，表示它所修饰的名词的性能和用途，和它所修饰的名词在逻辑上没有主谓关系；
现在分词作定语时，表示它所修饰的名词正在进行的动作，和它所修饰的名词在逻辑上有主谓关系，常可以扩展成一个定语从句。
如：a swimming girl＝a girl who is swimming 一个在游泳的姑娘
        a walking stick＝a stick that is used for walking 一根拐杖
（2）现在分词作定语有时可以后置，而动名词则通常只能放在它所修饰的名词之前。
如：The girl wearing glasses is one of his students. 戴眼镜的那个女孩是他的一个学生。
        I bought some reading materials. 我买了一些阅读材料。

动名词的用法：

1、作主语：
例如：Fighting broke out between the South and the North. 南方与北方开战了。　
2、作宾语：　　
a. 有些动词可以用动名词作宾语。
例如：admit承认 appreciate感激 avoid避免 complete完成 consider认为 delay耽误 deny否认 detest讨厌 endure忍受 enjoy喜欢 escape逃脱 fancy想象 finish完成 imagine想象 mind介意 miss想念 postpone推迟 practice训练 recall回忆 resent讨厌 resume继续 resist抵抗 risk冒险 suggest建议 face面对 include包括 stand忍受 understand理解 forgive宽恕 keep继续
例如：Would you mind turning down your radio a little, please? 你把收音机音量调小一点，好吗？
      　 The squirrel was lucky that it just missed being caught. 这松鼠幸运得很，刚逃避了被逮住的厄运。　　　　　
b. 有些结构后面可以用动名词作宾语或其他成分。
例如：admit to prefer...to burst out keep on   insist on   count on   set about   put off   be good at   take up   give up   be successful in be used to lead to devote oneself to   object to stick to no good   no use be fond of look forward to be proud of   be busy can't help be tired of   be capable of   be afraid of think of
3、作表语，对主语说明、解释：
例如：Her job is washing, cleaning and taking care of the children. 她的工作是洗刷、清扫和照顾孩子。
比较：She is washing, cleaning and taking care of the children.
4、作定语，一般表示所修饰名词事物的用途：
例如：a writing desk=a desk for writing 写字台
            a swimming pool=a pool swimming 游泳池
有些动名词作定语，与所修饰的名词关系比较复杂。
例如：boiling point=a temperature point at which something begins to boil 沸点
            a walking tractor=a tractor which a driver can operate while he or she is walking behind it 手扶拖拉机

动名词知识体系：

动名词与不定式用法对比：

虚拟语气的概念：

虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。在条件句中的应用条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。

虚拟语气在条件句中的应用：

一、真实条件句：
真实条件句真实条件句用于陈述语气，假设的情况可能发生，其中if是如果的意思。
时态关系句型：条件从句：一般现在时；主句：shall/will+动词原形
如：If he comes, he will bring his violin.
典型例题：
The volleyball match will be put off if it___.
A. will rain
B. rains
C. rained
D. is rained
答案：B。真实条件句主句为将来时，从句用一般现在时。
注意：1）在真实条件句中，主句不能用be going to表示将来，该用shall, will。
如：（错） If you leave now, you are never going to regret it.
         （对） If you leave now, you will never regret it.
            2）表示真理时，主句谓语动词便不用shall(will)+动词原形，而直接用一般现在时的动词形式。

二、非真实条件句：
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
1）时态：可以表示过去，现在和将来的情况。它的基本特点是时态退后。
a. 同现在事实相反的假设。
句型：从句：一般过去时；主句：should(would)+动词原形
如：If they were here, they would help you.
b.表示于过去事实相反的假设。
句型：条件从句：过去完成时；主句：should(would)have+过去分词
如：If she had worked harder, she would have succeeded.
        The rice would not have been burnt if you had been more careful.
        If my lawyer had been here last Saturday, he would have prevented me from going.
c.表示对将来的假想句型：
条件从句：一般过去时；主句：should+动词原形
                   从句： were+不定式；主句：would+动词原形 should+动词原形
如：If you succeeded, everything would be all right.
        If you should succeed, everything would be all right.
        If you were to succeed, everything would be all right.

三、混合条件句：
主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。
如：If you had asked him yesterday, you would know what to do now. （从句与过去事实相反，主句与现在事实相反。）
        If it had rained last night (过去), it would be very cold today (现在).

比较if only与only if：

only if表示“只有”；if only则表示“如果……就好了”。If only也可用于陈述语气。
如：I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。
        If only the alarm clock had rung. 当时闹钟响了，就好了。
        If only he comes early. 但愿他早点回来。
It is(high) time that It is(high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。
如：It is time that the children went to bed.
        It is high time that the children should go to bed.
need“不必做”和“本不该做"”
didn't need to do表示：过去不必做某事，事实上也没做。
needn'thavedone表示：过去不必做某事，但事实上做了。
如：John went to the station with the car to meet Mary, so she didn't need to walk back home.
        约翰开车去车站接玛丽，所以她不必步行回家了。
        John went to the station with the car to meet Mary, so she needn't have walked back home.
        约翰开车去车站接玛丽，所以她本不必步行回家了。(Mary步行回家，没有遇上John的车。)
典型例题：
There was plenty o ftime. She___.
A. mustn't have hurried
B. couldn't have hurried
C. must not hurry
D. needn't have hurried
答案：D。needn't havedone. 意为"本不必"，即已经做了某事，而时实际上不必要。 Mustn't have done用法不正确，对过去发生的事情进行否定性推断应为couldn't have done,“不可能已经”。must not do不可以（用于一般现在时）

特殊的虚拟语气词should 的用法：

1）It is demanded/necessary/a pity+that…结构中的主语从句的谓语动词要用should加动词原形，should可省略。
句型：
如：It is suggested that we(should) hold a meeting next week.
        It is necessary that he(should) come to our meeting tomorrow.
2）在宾语从句中的应用在表示命令、建议、要求等一类动词后面的从句中。order, suggest, propose, require, demand, request, insist, command, insist+(should)do
如：I suggest that we(should) hold a meeting next week.
       He insisted that he(should) be sent there.
注意：如suggest, insist不表示“建议”或“坚持要某人做某事时”，即它们用于其本意“暗示、表明”、“坚持认为”时，宾语从句用陈述语气。
如：The guard at gate insisted that everybody obey the rules.
判断改错：（错）You pale face suggests that you(should) be ill.
                    （对）Your pale face suggests that you are ill.
                    （错）I insisted that you(should) be wrong.
                    （对）I insisted that you were wrong.
3）在表语从句，同位语从句中的应用在suggestion, proposal, idea, plan, order, advice等名词后面的表语从句、同位语从句中要用虚拟语气，即（should）+动词原形。
如：My idea is that we(should) get more people to attend the conference.
        I make a proposal that we(should) hold a meeting next week.

虚拟语气知识体系：

	条件从句中的谓语动词形式	主句中的谓语动词形式
与过去事实相反	had+过去分词	should/would+have+过去分词
与现在事实相反	过去式	should/would+动词原形
与将来事实相反	1、过去式	should/would+动词原形
	2、should+动词原形	should/would+动词原形
	3、were to+动词原形	should/would+动词原形

虚拟条件句的倒装：

虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had移到从句句首，实行倒装。
如：Were they here now, they could help us.=If they were here now, they could help us.
        Had you come earlier, you would have met him=If you had come earlier, you would have met him.
        Should it rain, the crops would be saved.=Were it to rain, the crops would be saved.
注意：在虚拟语气的从句中，动词“be”的过去时态一律用“were”，不用was，即在从句中be用were代替。
如：If I were you, I would go to look for him. 如果我是你，就会去找他。
        If he were here, everything would be all right. 如果他在这儿，一切都会好的。
典型例题：_____to do the work, I should do it some other day.
                   A. If were I
                   B. I were
                   C. Were I
                   D. Was I
答案：C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前，变成were, should, had+主语的形式。
但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do.，而不能说Weren't I to do。
