中考现在完成时讲解及练习
学科教师辅导讲义 讲义编号 学员日校: 年 级:八年级 课时数:3 学员姓名: 辅导科目: 英语 学科教师: 学科组长签名 组长备注 课 题 现在完成时复习 授课时间: 备课时间: 教学目标 学生熟练运用现在完成时 重点、难点 过去分词的变化规则;现去完成时的用法;现在完成时与一般过去式的区别 考点及考试要求 现在完成时是中考必考项,也是难点之一,学生应掌握现在完成时的基本用法,并多加练习及思考 教学内容 【第一环节:知识点讲解】 I 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。 肯定 have/has done 否定 haven’t/hasn’t done 疑问 have/has/haven’t/hasn’t 提前 II 过去分词变化规则 规则动词的变法和过去式相同,即直去双改。 直:直接加-ed 如played, missed, matched, wished, stayed, picked, 去:去e后加-ed. 如 saved, hoped, wasted, lived, waved, moved 双:以重读闭音节结尾的词双写后面是辅音字母后加-ed 如: stopped, fitted. stepped, stirred 改:以辅音字母+y为结尾的词变y为i后加-ed 如:fried, tidied, carried III 定义:现在完成时(Present perfect)过去发生并且已经完成的动作对现在造成影响或后果,过去某 一时间开始并一直持续到现在并且有可能还会持续的动作或状态。 1: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。 e.g. He has lived here for three years. ( 已经住了三年并且有可能继续住下去) I haven't seen her for four years. <注> 因为此时是强调持续一段时间并有可能继续持续下去,所以如果是肯定句的话动词必须要是延续性的,否定句不需要 【例题解析】. The old man ________ for over three years. A. has died B. has been dead C. died D. is died 解析:此处答案误区A. 此句后有for over three years(持续三年多)可知应用现在 完成时,而此句又是肯定句,所以动词必须是延续性的。选项中died 是不可延续的,且是不及物的,所以排除A、C、D。而be是助动词,可延续表示一状态,所以此答案选B. 2: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。 -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) <注> 此处强调过去的动作对现在造成的影响。 【例题解析】10、—______ you ___ your homework yet ? —Yes . I _____ it a moment ago . A. Did ; do ; finished B. Have ; done ; finished C. Have ; done ; have finished D. will ; do ; finish 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。 (例题) Harry Potter is a very nice film .I_______ it twice . A. will see B. have seen C. saw D.see d..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。 【例题解析 Zhao Lan ______already ______in this school for two years . A. was ; studying B. will ; study C. has ; studied D. are ; studying 解析:此题目相当简单,already 与后面的时间状语就可以断定一定是完成 时态,而选项中只有C选项是完成时态。 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。 He has been there three times the last few days. 近几天他去过那里三次了。 —Our country ______ a lot so far . —Yes . I hope it will be even _____ _ . A. has changed ; well B. changed ; good C. has changed ; better D. changed ; better d.用包括“现在”在内的时间状语,如:now, today, this morning (month, year, term)等。 例如:-Have you met him today? -No, I haven't. How many times have you been there this year? (2)现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始, 一直持续到现在。如:I haven't seen him for two years. 但是,像come,arrive,buy等终止性动词不能 与表示“一段时间”的状语连用。要用,必须改为“be(在)”等延续性动词来表述。现归纳总结一下由 非延续性动词到延续性动词的转换: arrive→be here begin(start)→be on die →be dead come back→be back leave →be away fall ill(sick,asleep)→be ill(sick,asleep) get up→be up go out →be out finish →be over put on →wear 或be on open →be open join →be in或 be a member of… close →be closed go to school→be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study→study come to work→work等 如:He has been a soldier for three years. His father has been dead for two years. The film has been on for ten minutes. We have studied English for three years. 4. 注意事项 (1)have been(to)与have gone( to)的区别:have been(to)表示“去过某地(现在已经回来了)”,可用于各人称;have gone(to)表示“去某地了(说话时某人不在当地)”,常用于第三人称,前者可与once ,never, several times等连用,后者则不能。如:They have been to Beijing twice.他们去过北京两次。 He has gone to Beijing . 他去北京了。 (例题)Miss Green isn't in the office . she_______ to the library . A.has gone B. went C.will go D. has been (解析) “have/has gone to + 地点”表示“某人去了某地(还未回来)”,指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”,常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地(但现在已不在那儿)。”故16的正确答案为A。 (2)如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时。 如:It is two years since his father died. =His father has been dead for two years.他父亲去世已有两年了。 (3)终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段时间的状语连用。 如:I haven't left here since 1997. (4) 在提问现在完成时的时间状语时通常用 how long How long have you lived here? (例题)____ has Mr White been a member of Greener China since he_____ to China? A. How soon, comes B. How often, got C. How long, came D. How far, arrived 解析:根据排除法此处选C. 二、现在完成时与一般过去时的区别 现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。动作或状态发生在过去,但它的影响现在还存在;而一般过去时表示过去的事实,不表示和现在的关系。 I have just been to London. I went there last month. 我刚去过伦敦,是上个月去的。 1. 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。 I saw this film yesterday.(强调看的动作发生过了,不涉及现在) I have seen this film. (强调对现在的影响,电影的内容已经知道了。) 2. 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, 具体的时间状语 (例题)____ you _____ the text yet ? Yes, we ____ it two hours ago. A. Did…copy…did B. Have…copied…have C. Have…copied…did D. Did …copy…had 解析:有yet可知前面应用现在完成时态;有two hours ago 可知,后应用过去时,所以答案C. 共同的时间状语: this morning, tonight, this April, now, once,before, already, recently,lately 现在完成时的时间状语 for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always, 【第二环节:课堂练习】 1.

Shanghai-born novelist Lu Shi’e wrote a fantasy novel called New China in 1910. In the book he described a dream where trains were running underground, an iron bridge crossed the Huangpu River and Shanghai hosted a successful World Exposition in the underdeveloped Pudong area at that time. The blueprint described in the novel became real exactly after 100 years. On May 1, 2010, the World Exposition, with 158 years of history, drew back its curtain from Shanghai. According to a source at the Organizing Committee (组织委员会) of the World Exposition 2010 Shanghai, it is expected to attract more than 70 million visitors, making it the most popular exposition in history. And in fact, Shanghai really has achieved the goal. It is also the first time the World Exposition is held in a developing country. About 600 years ago, Shanghai was just a small fishing village in China’s eastern coastal area. It grew into a commercial (商业的) city and became among the first Chinese cities to open its door to the world. Along this way, it became the economic and commercial hub of China. Today Shanghai is developing into an international metropolis (大都会). 1. Where was the novelist Lu Shi’e born? _____________________________________________________________. 2.
