一般过去时与现在完成时的用法区别
一般过去时与现在完成时区别专题 一、前言： 初一下学期同学们学习了一般过去时态的相关知识，即将到来的初二上学期英语学习中，现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时，对现在完成时进行初步讲解，希望使同学们读新学期的学习有所准备。 二、现在完成时 1. 现在完成时的构成 现在完成时是由助动词have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。 2. 现在完成时的用法 现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。 We are good friends.(现在的情况） I knew him in 1997.（过去的动作） We have known each other since 1997. （现在完成时把过去的动作和现在联系起来并着眼于现在） （1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如： -Have you had lunch yet? -Yes, I have. I've just had it. 你（已经）吃午饭了吗？我刚刚吃过。（现在我不饿了） （2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常带有for和since等表示一段时间的状语。 如：He has taught here since 1981 他自1981年就在这儿教书。（可能还要继续教） I haven't seen her for four years. 我有四年没见到她了。 （3）表示说话前发生过一次或多次的动作，现在成为一种经验，一般译为汉语“过”，常带有twice,ever, never,three times等时间状语。 如：I have been to Beijing twice.我去过北京二次。 3.现在完成时的时间状语 （1）现在完成时属于现在时范围，故不能和过去的时间状语连用。如：yesterday,last Sunday,in1990,three years ago等。但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。 如：We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。 b.用ever 和never。多用于否定或疑问句中，表示“曾经”或“从未“等。 如：-Have you ever been to the Great Wall? 你曾经去过长城吗？ -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语，如just, before, up to now, the past few years等。 例如：I have seen her before, but I can not remember where. 我以前见过她，但记不起在哪里见过。
一般过去时-现在完成时和过去完成时
一般过去时，现在完成时和过去完成时 一般过去时态表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用，也表示过去经常或反复发生的动作，常和表示频度的时间状语连用，试看下列例句： 1. I was in the classroom yesterday morning 2. My father was at work last week. 3. I visited the Palace Museum three weeks ago. 4. He always went to work by bus last year. 5. I wrote home once a week at college. 1. yesterday或以其构成的短语：yesterday morning(afternoon, evening)等； 2. 由"last+一时间名词"构成的短语：last night, last year (winter, month, week)等； 3. 由"时间段+ago"构成的短语：a moment ago, a short time ago, an hour ago等； 4. 其它：just now或者由句子本身的时态所反映出来的。 现在完成时表示：(1)过去发生或已经完成的动作对现在造成的影响或结果, 常与already，just，yet，before，ever，never 等副词连用；(2)发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示），常与for（+时间段），since（+时间点或过去时的句子）连用。试看下列例句： 1.My father has brought many books for me , so I can do some reading now. 2.I have already finished my homework, so I can give it to my teacher now. 3.Kevin hasn't seen the film yet, so he has nothing to say about the film. 4.This is the best film I have ever seen. 5.Mary has been ill for three days. 6.I have lived here since 1998. 现在完成时不能和表示过去的时间状语连用，如yesterday, last year, two days ago, just now 等等，但可以和already, yet, sometimes, always, before, recently,ever, never等连用。

现在完成时和过去完成时的区别
I have cleaned the classroom .（强调扫地所产生的结果：地干净了！） We have lived here for ten years.（“住”从过去持续到现在的动作用现在完成时） We have lived here since we came here.（“住”是从过去持续到现在的动作用现在完成时） Mr Green had lived in New York for ten years before he came to China.("来”中国已过去，而先前“住”在纽约更过去！）（另外注意：“住”在纽约可没有持续到现在！） We had learned 1000 words by the end of last term. （“上期期末”已过去，而是在其前“学”的就更过去了！） 一、从结构上区别 现在完成时： 主语 + have / has（not） + 过去分词 过去完成时： 主语 + had (not) + 过去分词 (二)从时间状语区别 现在完成时: 常用的时间状语包括“now, today, tonight, this week, this year, already, yet, just, recently…etc”。 过去完成时: 常用的时间状语包括“by, at, before等构成的短语”。 注意：当表示一段时间，现在完成时和过去完成时都可以用for 或since引导的状语。 例如： The meeting had begun when we got there. 我们到那儿时，会议已经开始了。 We had learned about 500English words when we were 6 years old. 我们六岁时就已经学了500个英语单词。
一般过去时和现在完成时用法区别(详细点)
一般过去时和现在完成时用法区别（详细点） 1) 经常性或习惯性的动作，常与表示频腮度的时间状语连用。时间状语：every…, sometimes, at…, on Sunday I leave home for school at 7 every morning. 2) 客观真理，客观存在，科学事实。 The earth moves around the sun. 不受时间限制的 Shanghai lies in the east of China. 客观存在 表示格言或警句中。 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：Columbus proved that the earth is round.. 3) 现在时刻的状态、能力、性格、个性、特征。 I don't want so much. Ann Wang writes good English but does not speak well. 比较：Now I put the sugar in the cup. I am doing my homework now. ※4)由连词if unless before as soon as when once however 等引起的时间(条件、让步)状语从句,需要用一般现在时,表示将来时. 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。再如：Now watch me, I switch on the current and stand back. 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。 现在完成时用法解析 1.构成 现在完成时是由助动词have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。 2.用法 （1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如： -Have you had lunch yet? -Yes,I have. I've just had it. 你（已经）吃午饭了吗？我刚刚吃过。（现在我不饿了） （2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常带有for和since等表

过去完成时与现在完成时的区别及用法
现在完成时和过去完成时这两个时态的相似之处是动作都发生在过去，差别是两个时态所对应的时间参照点不一样。 现在完成时的动作发生在过去，但是时间参照点是现在 过去完成时的动作发生在过去，但是时间参照点是过去的某一时间。请看下面两个例句 -I have lived in Thailand for five years. (我目前在泰国已经住了五年了) live(居住)是上面例句的谓语，那么这个动作显然是发生在过去(五年前)，但是一直持续到现在，我们的时间参照点是“现在、当下”。我们再看下面一个例句： I had lived in Thailand for five years before I went to China. (在我来中国之前，我已经在泰国住了五年了) live这个动作发生在过去，是前面句子的谓语，但是整句话的时间参照点变成了before I went to China，这个动作也是过去的一个时间点，所以我们要把go 变成went。所以从上面两个例句中大家可以看出，其实这两个时态的不同之处就在于时间参照点的不同。总结一下，现在完成时用来表示过去发生的动作对现在造成的影响，通常我们可以用现在完成时态表达三类情况： 第一、经验 -I have seen that movie before. (我之前看过那部电影) 凡是我们谈论之前的经验，看过、听过、吃过、去过、读过等等的经验都可以用现在完成是来表达，那么上面例句的意思是我不仅看过那部电影，而且我对电影的情节还有印象。 第二、持续 -I have known John since we were kids. (当我们还是小孩的时候我就认识John了) Know(认识)这个动作发生在过去，而参照点是现在，说明我们现在还是朋友，而且友谊还可能继续持续下去 第三、改变 -I have bought a new car. (我买了一辆新车) buy这个动作发生在过去，但是时间参照点是现在，其实言下之意是我不仅买了一辆新车，而且这辆新车我现就在我家，我随时都能用。之前没有车，现在有车了，这就是改变。 那么过去完成是则是谈论过去的两个动作谁先谁后的问题，请看下例：-The plane left at 5 pm. (飞机下午五点起飞的) -We arrived at the airport at 6 pm. (我们六点到的机场) 上面两个句子都是一般过去时，表示两件完整的发生在过去的事情，这个时候我们可以用过去完成时态把这两个句子串起来，就变成了下面的句子：-The plane had left when we arrived at the airport.
