现在完成时的概念:  

现在完成时用来表示之前已发生或完成的动作或状态,其结果的影响现在还存在;也可表示持续到现在的动作或状态。其构成:have(has)+过去分词。


现在完成时共有四种主要用法:   

一、现在完成时表示影响:
该用法的现在完成时表示一个过去发生的动作在过去已经完成,并且这个过去发生并完成的动作对现在有影响或结果,同时说话者强调的或感兴趣的就是这个影响或结果,如汉语说“他已离开这个城市了”,其中的“离开”肯定发生了,它对现在的影响或结果就是“他现在已不在这个城市了”;又如汉语说“有人把窗户打破了”,显然“打破窗户”这一动作发生在过去,并且在过去已经完成了,但说话人强调的重点是打破窗户对现在的影响—窗户现在仍是破的。
如:He has left the city. 他已离开这个城市。(结果:他不在这个城市。)   
        Someone has broken the window. 有人把窗户打破了。(结果:窗户仍破着。)   
        I have lost my pen. 我把钢笔丢了。(结果:我现在无钢笔用。)   
        He has finished his work. 他把工作做完了。(结果:他现在可以做其他的事了。)   

二、现在完成时表示持续:   
该用法的现在完成时表示一个过去发生的动作或开始的状语在过去并未完成或结束,而是一直持续到现在,并且有可能继续下去(也可能到此结束),如汉语说“他在我们学校教书已有30年了”,显然“他在我们学校教书”是从30年前开始,并且一直教到现在,已经持续了30年;又如汉语说“自上个星期以来他一直很忙”,显然“忙”是从上个星期开始的,并且这一“忙”就一直忙到现在。
如:He has taught in our school for 30years. 他在我们学校教书已有30年了。   
        He has been busy since last week. 自上个星期以来他一直很忙。   
        He has worked for us ever since he left school. 他离开学校以后就一直为我们工作。   

三、现在完成时表示重复:   
即表示从过去某个时间直到现在的这个时间范围内不断重复发生的动作或情况,并且这个不断重复的动作有可能继续下去,也有可能到现在就结束。
如:How often have you seen her? 你隔多少见她一次?   
        My father has always gone to work by bike. 我父亲一向骑车上班。   

四、现在完成时表示将来:   
同一般现在时可以表示将来一样,现在完成时也可以在时间状语从句里表示将来。
如:I'll wait until he has written his letter. 我愿等到他把信写完。   
        When you have rested, I'll show you the garden. 等你休息好之后,我领你看我们的花园。


现在完成时知识体系:

 


比较一般过去时与现在完成时:

1)一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。
2)一般过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。一般过去时的时间状语:yesterday, last week,…ago, in1980, in October, just now等,皆为具体的时间状语。现在完成时的时间状语:for, since, sofar, ever, never, just, yet, till/until, up to now, in past years,always等,皆不确定的时间状语。共同的时间状语:this morning, tonight, this April, now, already, recently, lately等。
3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know。一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。
例如:I saw this film yesterday.(强调看的动作发生过了)
            I have seen this film.(强调对现在的影响,电影的内容已经知道了)
            Why did you get up so early?(强调起床的动作已发生过了)
            Who hasn't handed in his paper?(强调有卷子未交,疑为不公平竞争)
            He has been in the League for three years.(在团内的状态可延续)
            He has been a League member for three years.(是团员的状态可持续)  
句子中如有过去时的时间副词(如yesterday, last, week, in1960)时,不能使用现在完成时,要用过去时。
(错)Tom has written a letter to his parents last night.
(对)Tom wrote a letter to his parents last night.


部分倒装的概念:

倒装英语句子的主语通常位于谓语动词之前,这种语序被称为正常语序。但有时出于修辞或某种特殊的语法结构的需要,需要将谓语动词放在主语之前,这种语序则叫倒装语序。主语和助动词倒置叫部分倒装。


部分倒装:

1、含有否定意义的副词位于句首时的倒装:
在正式文体中,never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere等含有否定意义的副词若位于句首,则其后要用部分倒装:
如:I shall never forgive him./ Never shall I forgive him. 我永远不会宽恕他。
        He seldom goes out for dinner./Seldom does he go out for dinner. 他很少出去吃饭。
        She hardly has time to listen to music./Hardly does she have time to listen to music. 他几乎没时间听音乐。
        He little realize show important this meetingis./Little does he realize how important this meeting is. 他不甚明白这个会议的重要性。   
        We had no sooner reached the airport than the plane took off./No sooner had we reached the airport than the plane took off. 我们刚到机场,飞机就起飞了。
:(1)对于not…until句型,当not until…位于句首时,其后的主句要用倒装语序:
如:He didn't leave the room until the rain stopped./Not until the rain stopped did he leave the room. 雨停了之后他才离开这房间。
        (2)某些起副词作用的介词短语,由于含有否定词,若位于句首,其后要用部分倒装:
如:On no accounts must this switch be touched. 这个开关是绝不能触摸的。
        In[Under] no circumstances will I lend money to him. 无论如何我也不会再借钱给他了。但是,in no time(立即,马上)位于句首时,其后无需用倒装语序:
如:In no time he worked out the problem. 他马上就算出了那道题。
2、“only+状语”位于句首时的倒装:
当一个状语受副词only的修饰且置于句首时,其后用部分倒装语序:
如:Only then did he realize that he was wrong. 到那时他才意识到他错了。
        Only in this way are you able to do it well. 你只有用这种方法才能把它做好。
        Only when he returned home did he realize what had happened. 当他回到家里时,才知道出了什么事。
3、“so+形容词或副词”位于句首时的倒装:
副词so后接形容词或副词位于句首时,其后用部分倒装:
如:So cold was the weather that we had to stay at home. 天气太冷,我们只好呆在家里。
        So fast does light travel that we can hardly imagine its speed. 光速很快,我们几乎没法像它的速度。
        So sudden was the attack that we had no time to escape. 袭击来得非常突然,我们来不及逃跑。
4、“So+助动词+主语”倒装:
当要表示前面提出的某一肯定的情况也同样适合于后者,通常就要用“So+助动词+主语”这种倒装结构:
如:You are young and so am I. 你年轻,我也年轻。
        She likes music and so do I. 她喜欢音乐,我也喜欢。
        If he can do it, so can I. 要是他能做此事,我也能。
:(1)若前面提出某一否定的情况,要表示后者也属于同样的否定情况,则应将其中的so改为neither或nor:
如:You aren't young and neither am I. 你不年轻,我也不年轻。
        She hasn't read it and nor have I. 她没有读它,我也没有读。
        (2)注意该结构与表示强调或同意的“so+主语+特殊动词”结构的区别:
如:"It was cold yesterday." "So it was."“昨天很冷。”“的确很冷。”
        "Father, you promised." "Well, so I did."“爸爸,你答应过的。”“嗯,是答应过。”
5、由not only…but also引出的倒装:
当not only…but also位于句首引出句子时,not only后的句子通常用部分倒装形式:
如:Not only is he a teacher, but he is also a poet. 他不仅是一位教师,而且是一位诗人。
        Not only did he speak more correctly, but he spoke more easily. 不仅他讲得更正确,也讲得更不费劲了。
6、虚拟条件句省略if后构成的倒装:
当if引导的虚拟条件从句中含有had, were, should等时,如将if省略,则要将had, were, should等移到主语前,构成倒装句:
如:Had you come yesterday, you would have seen him. 若你昨天来,你就会见到他了。
        Should you require anything give me a ring. 如果需要什么,可以给我打电话。
        Were it not for your help, I would still be homeless. 要不是你帮助,我会仍然无家可归。
注:省略if后提前的had不一定是助动词:
如:Had I money, I would buy it. 假若我有钱,我就会买它。
