英语现在完成时精讲+精练(附答案)

英语现在完成时精讲+精练(附答案)英语中的现在完成时表示过去发生的事情对现在产生的影响或仍在继续的动作，结构为“have/has + 过去分词”。

本篇文章将对现在完成时的用法进行详细讲解和练。

一、现在完成时的主要用法现在完成时有以下三种主要用法：1. 表示过去发生的动作对现在产生的影响例如：- I have lost my phone.（我手机丢了。

）- She has forgotten the meeting.（她忘了会议。

）以上两句话中，手机丢了和会议被忘了都是在过去发生的事情，但是现在失去手机和忘记会议都对现在产生影响，因此需要用现在完成时来表达。

2. 表示从过去某个时间开始一直持续到现在的动作例如：- I have worked here for two years.（我在这里工作已经两年了。

）- They have been married since 2010.（他们自 2010 年以来就结婚了。

）以上两个句子都是表示从过去某个时间开始到现在一直持续的动作，需要用现在完成时来表达。

3. 表示刚刚发生的动作例如：- I have just finished my homework.（我刚刚完成了我的作业。

）- He has just arrived.（他刚刚到了。

）以上两句话中，都是刚刚发生的动作，需要用现在完成时来表达。

二、现在完成时的结构现在完成时的结构为“have/has + 过去分词”：- have + 过去分词，用于第一人称复数（we）、第二人称复数（you）和第三人称复数（they）以及第一人称单数（I）与第二人称单数（you）构成疑问句和否定句。

- has + 过去分词，用于第三人称单数（he、she、it）构成一般句。

例如：- I have visited London twice.（我去过伦敦两次。

）- Have you finished your homework?（你完成作业了吗？）- She has seen the movie before.（她之前看过这部电影。

中考初中语法之现在完成时讲解+练习

中考初中语法之现在完成时讲解+练习现在完成时表达式have done(动词过去分词)用法：1. 表示过去发生的动作或状态一直持续到现在，还有可能要持续下去（强调持续性），常用for＋时间段/since＋时间点连用I have studied English for five years/since five years ago.2. 表示过去发生的动作或状态对现在造成的影响或结果（强调影响性）Tom is pleased that he has found his lost watch.—Why do you look so tired?—Because we have worked for three hours without stopping.现在完成时表达式have done变式：1. have been to 去过(回来了)2.have gone to 去了(没回来)3. have been in 在某地呆了.....例句：1. I have never been to Shanghai.2.--- Where is your mother?---My mother has gone to the supermarket.3.John has been in China for five years.注意：在“it is the first/second...time that...。

”或在“it/this/that is the +最高级+名词+that...。

”结构中，that从句中的动词常用现在完成时；表示到说话时为止动作发生过几次。

在“it + be...+since从句”这一结构中，be可用一般现在时或现在完成时，since从句一般用过去时。

have/has/had +been +动词的现在进行时。

初中_中考英语现在完成时时态仔细讲解与习题（可编辑修改word版）初中现在完成时时态讲解一、注意弄清时态的实际意义现在完成时表示的是在过去某个时间开始并持续到现在的动作/状态,或者过去的动作或状态对现在造成的影响或结果。

They have left. --他们已经离开了,也就是说现在他们人不在这里I have had my lunch. --我已经吃过午饭了,也就是说我现在不饿也可表示持续到现在的动作或状态，或有可能有可能停止，或有可能继续延续下去。

He has learned English since 2001. -从2001 年开始学的,现在还在继续学着呢二、基本句型结构现在完成时的构成形式：have /has (助动词)+done(过去分词)I/You/They/We have talked . He/She has talked.现在完成时的否定结构就是在助动词have 或has 后加上否定词not；I/You/They/We have n’t(have not) talked . He/She hasn’t(has not) talked.其一般疑问句就是将助动词have 或has 提到句首，Have I/You/They/We talked . Has he/she talked.肯定的简略回答是：Yes，主语＋have/has.，否定的简略回答是：No，主语＋have/has not.。

如：I have seen the film. →Have you seen the film？Yes，I have./No，I haven’t.三、注意掌握两种基本用法1.“过去的经历”：动作发生在过去的某一时刻且已经结束，但未说明动作发生的具体时间或情景，强调该经历(即动作发生后)对现在所造成的影响或产生的结果。

如：I have heard of the man. 我听说过这个人。

中考初中英语主要时态系列讲座(五)----现在完成时精讲及练习(含答案)

中考初中英语主要时态系列讲座（五）----现在完成时精讲及练习（含答案）中考初中英语主要时态系列讲座（四）----现在完成时精讲及练习考点一：现在完成时的基本用法现在完成时表示过去发生的动作对现在的影响，还表示动作从过去某时开始，一直延续到现在，并有可能延续下去。

现在完成时是中考英语中重要的时态考查对象，且现在完成时对我们中国学生而言比较难以掌握。

因此，本讲座主要以表格的形式简化对现在完成时的理解。

表（一）：现在完成时的基本句式注意：现在完成时要求句中的动词使用过去分词形式。

动词过去分词分为规则与不规则两种形式，规则动词的过去分词变化规则与动词过去式相同，而不规则动词的过去分词则须逐一记忆，详细见课本或考纲后附的不规则动词表。

这里就不再列出。

表（二）：现在完成时的用法与对应的时间状语。

（江苏镇江）---The drama series The Thunder (破冰行动) hits screens these days.---Oh. What a pity! I ____________ any of them yet,A. doesn't watchB. didn't watchC. won't watchD. haven't watched 【析】正确答案D。

句意是：连续剧《破冰行动》这些日子上映了。

哦，真可惜！我一节也没有看过。

根据句末的副词yet可知，到目前说话人还没有观看，因此，用现在完成时。

所以，正确答案为D。

【典型考例2】（北京） Our school life a lot since . We have more activities now.A. changesB. changedC. will changeD. has changed【析】正确答案D。

句意是：从年起，我们的校园生活发生了巨大变化。

我们现在有了更多的活动了。

根据句末的时间状语since 可知，表示动作从过去一直延续到现在，应使用现在完成时。
