一般现在时
虚拟语气

一般现在时的概念：

表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。

一般现在时的用法：

1）经常性或习惯性的动作，常与表示频度的时间状语连用。常用的时间状语有every...，sometimes，at...，on Sunday等。
例如：I leave home for school at 7 every morning. 每天早上我七点离开家。
2）客观真理，客观存在，科学事实。
例如：The earth moves around the sun. 地球绕太阳转动。　
            Shang hai lies in the east of China. 上海位于中国东部。
3）表示格言或警句。
例如：Pride goes before a fall.　骄者必败。　
注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。
例如：Columbus proved that the earth is round. 哥伦布证实了地球是圆的。
4）现在时刻的状态、能力、性格、个性。
例如：I don't want so much. 我不要那么多。　
           Ann writes good English but does not speak well. 安英语写得不错，讲的可不行。
比较：Now I put the sugar in the cup. 把糖放入杯子。　　　
            I am doing my homework now. 我正在做功课。　　
第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。
第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。

一般现在时知识体系：

一般现在时用法拓展：

1、一般现在时表将来：
1）下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来，主要用来表示在时间上已确定或安排好的事情。
例如：The train leaves at six tomorrow morning. 火车明天上午六点开。　　　
       —When does the bus star? 汽车什么时候开
       —It stars in ten minutes. ？十分钟后。
2）以here, there 等开始的倒装句，表示动作正在进行。
例如：Here comes the bus.=The bus is coming. 车来了。　　　
            There goes the bell.=The bell is ringing. 铃响了。
3）在时间或条件句中。
例如：When Bill comes（不是will come）, ask him to wait for me. 比尔来后，让他等我。　　　
            I'll write to you as soon as I arrive there. 我到了那里，就写信给你。
4）在动词hope, take care that, make sure that 等的宾语从句中。
例如：I hope they have a nice time next week. 我希望他们下星期玩得开心。　　　
            Make sure that the windows are closed before you leave the room. 离开房间前，务必把窗户关了。
2、一般现在时代替一般将来时：
When, while, before, fter, till, once, as soon as, so long as, by the time, if, in case（that）, unless, even if, whether, the moment, the minute, the day, the year, immediately等引导的时间状语从句，条件句中，用一般现在时代替将来时。
例如：He is going to visit her aunt the day he arrives in Beijing. 他一到北京，就去看他姨妈。
3、一般现在时代替一般过去时：
1）"书上说"，"报纸上说"等。
例如：The news paper says that it's going to be cold tomorrow. 报纸上说明天会很冷的。　
2）叙述往事，使其生动。
例如：Napoleon's army now advances and the great battle begins. 拿破仑的军队正在向前挺进，大战开始了
4、一般现在时代替现在完成时：
1）有些动词用一般现在时代替完成时，如hear, tell, learn, write, understand, forget, know, find, say, remember等。
例如：I hear（=haveheard）he will go to London. 我听说了他将去伦敦。　
            I forget（=have forgotten）how old he is. 我忘了他多大了。
2）用句型"It is…since…"代替"It has been…since…"。
例如：It is（=has been）five years since we last met. 从我们上次见面以来，五年过去了。
5、一般现在时代替现在进行时：
在Here comes…/There goes…等句型里，用一般现在时代替现在进行时。
例如：There goes the bell.铃响了。

时态一致：
　
1、如果从句所叙述的为真理或相对不变的事实，则用现在时。
例如：At that time, people did not know that the earth moves. 那时，人们不知道地球是动的。　
            He told me last week that he is eighteen.上星期他告诉我他十八岁了。　
2、宾语从句中的，助动词ought, need, must, dare的时态是不变的。
例如：He thought that I need not tell you the truth. 他认为我不必告诉你真相。

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。
