He usually sleeps for 12 hours every day. We’ve studied here since 2009. She has worked here for five years. It’s two years since I came to China. 练习：用since 和for填空 1.Jim has been in Ireland last Monday. 2.Jill has been in Ireland three days. 3.His aunt has lived in Australia 15 days. 4.Mike has been ill a long time. He has been in hospital 0ctober. 2）for 与since引导的时间状语可以进行相互替换

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。

现在完成时态与过去时态的区别

现在完成时态与过去时态的区别 1. 意义上的区别一般过去时态只是单纯地表示过去某一时间发生过的动作或者存在的状态, 和现在没有任何联系, 只着眼于过去. 现在完成时态重点强调与现在的联系, 表示过去发生的动作对现在造成的影响和结果, 属于现在时的范畴. 试比较下列例句: I have washed my shoes . 我刷过鞋了. 强调的是过去的某一时间发生的动作"洗" 对现在产生的影响是" 鞋是干净的" . I washed my shoes yesterday . 我昨天刷了鞋. 强调昨天做过"洗" 这个动作, 与现在鞋是否干净没有关系. My father has bought a new car . 我爸爸买了一辆新车. 强调在过去的某一时间发生的动作"买" , 对现在造成的结果是" 他有了一辆新车". My father bought a new car last Sunday . 我爸爸上个周日买了一辆新车. 强调上个周日"买" 这个动作发生过, 与爸爸现在是否有车无关. 也许这辆车是给别人的. 2. 时间状语的区别一般过去时态只能与表示过去的时间状语连用, 如 yesterday, la st week, three years ago, in 1990 , just now 等.

现在完成时态中的时间状语表达的时间是到现在为止. 如: just 刚刚, before 以前, "since / ever since +过去时间 " 自从...... 开始, ev er 曾经, never 从未, 未曾, "already" 已经 , " for+ 时间段"已有多长时间了. in the last/ past ten years 在过去的十年里, so far 到目前为止. up to now 直到现在, this week 这个星期等等. 二者的根本区别在于过去时强调事实，常有具体的时间状语标志，如，yesterday/5.oclock/this morning,just now,ago etc---, examples: 1.I met her a week ago. 2.We have a English class this morning. 而完成时有两种用法或意义 1，影响性：也是一个过去动作但却强调它对现在的影响,没具体时间点作时间状语，但常有，already,yet,before,just作状语。 (1).Have you had your breakfast,yet?(2).I have seen this movie before. (3).He has just finished his homework. 2.持续性：表动作从过去的一个点开始，一直持续到现在。（现在完成时）如果只需到过去的另一个点就是过去完成时。动词要用延续性的，还常有 for（引导线状时间状语），since（引导点状时间状语） (1).I have been worked here for 20 years./I have worked here since 20 years ago. (2).I have been a member of the League for 2 years.这里的be a member of 代替不可延续的动词短语join the League。

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

牛津译林版八年级下册 b 现在完成时

现在完成时 ⒈构成 Have/has +过去分词现在完成时的肯定式、否定式和疑问式：【提示】 ①现在完成时的肯定式和否定式有其缩写形式：have→’ve, has→’s.例如：She’s worked. =She has worked. I’ve not worked. = I haven’t worked. ②现在完成时的否定疑问句形式为：Have you not worked? Have they not worked? Has he not worked?其缩写形式为：Haven’t you worked? Haven’t they worked? Hasn’t he worked? ③现在完成时的简略回答形式为：Yes, I have. No, I have not/haven’t. ⒉用法

⑴过去动作产生的影响等表示过去发生的某一动作对现在造成的影响或产生的结果。在没有具体时间状语的情况下，现在完成时可以表示某一行为动作在说话之前已经完成，而其结果或影响至今仍然存在。因此，现在完车时这一时态强调的是过去的动作同现在的联系，也就是强调现在的影响和结果。例如： Someone has broken the window.（“打破”这一动作虽然发生在过去，但影响延续至今，其结果是窗子仍然是破的，The window is now broken.） I have lost my pen.（结果是：我现在无钢笔可用，I have no pen to use.） He’s locked the door.(结果是：现在门锁上了，我们进不去，Now the door is locked and we can’t go in.) The party has started. (The party started and now it is going on.) I’ve forgotten her name= I forgot her name. 他今天还没吃任何东西.(现在一定很饿了) _________________________________________________________________ 我已经吃过午饭了（现在不饿了） ____________________________________________________ ⑵过去的动作延续到现在和未来表示一个开始于过去，持续到现在，并可能继续下去的动作或状态，常同for, since引导的时间状语连用，或用于How long…（多久）句型中，表示持续的时间。例如： He has studied English for ten years.（可能继续学下去） She has lived here since then. He has been in Nanjing since 2003.

He usually sleeps for 12 hours every day. We’ve studied here since 2009. She has worked here for five years. It’s two years since I came to China. 练习：用since 和for填空 1.Jim has been in Ireland last Monday.
