初中英语主要时态系列(六)——现在完成时讲解和练习
初中英语主要时态系列(六)——现在完成时讲解及练习
1
现在完成时的基本结构
肯定句：主语+have/has+动词的过去分词+其他否定句：主语+have/has+not+动词的过去分词+其他一般疑问句：Have/Has+主语+动词的过去分词+其他特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他）
2
现在完成时的用法
1. 现在完成时用来表示过去已经完成的动作对现在造成影响或后果。也就是说，动作或状态发生在过去但它的影响现在还存在，强调的是现在。
I have already posted the photo.我已经邮寄出了照片。
与此种用法连用的时间状语时一些模糊的过去时间状语，如already（肯定句句中）, yet（否定句/疑问句句尾）, just, before, recently,still, lately,never等。
2. 现在完成时也可用来表示动作或状态发生在过去某一时刻，持续到现在并且有可能会继续持续下去。
He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。)
此种用法常与for（+时间段）,since（+时间点或过去时的句子）连用。谓语动词必须是延续性动词。
有些瞬间动词可变为延续动词：go out----be out finish----be over open----be open die----be dead
buy---have fall ill---be ill come back----be back catch a cold----have a cold
3
现在完成时常见考法
对于现在完成时的考查，多以单选、句型转换或词语运用的形式考查学生在具体语境中灵活运用时态的能力。在考试中，会让大家判断是否该用现在完成时，或者是考查“瞬间动词”不能与表示一段时间的状语连用”这一知识点。
【典型例题】
His father_____the party since 1978A.joind B.has joined C.was in D.has been in答案：D
解析：本题考查学生对现在完成时的熟练掌握。since 1978表达“自从1978年一直到现在”，表示这件事情从过去一直持续到现在，应该用现在完成时，而且动词必须是延续性动词，A、B均为瞬间动词，不能与时间段连用，故排除；C为一般过去时，也不行。
4
比较一般过去时和现在完成时的异同
1. 共同点：动作都是在过去完成。
I saw the film yesterday evening.I have seen the film before.（看电影这件事都是在过去完成的。）
2. 区别：
①现在完成时强调过去发生的动作对现在的影响和结果，而一般过去时与现在没有联系，只是说明某个动作发生的时间是在过去。
②一般过去时通常与具体明确的过去时间状语连用。如yesterday, last week , two years ago，just now，in 2002 等；而现在完成时则常与 just ,already ,ever ,never 等模糊的过去时间状语和 these days ,this week ,since..., for... 等表示一段时间的状语连用。
【典型例题】
—______ you your homework yet ?—Yes . I _____ it a moment ago .
A.Did ; do ; finished
B.Have ; done ; finished
C.Have ; done ; have finished
答案：B
解析：本题考查一般过去时和现在完成时的用法区别。问句中的yet表明应该用现在完成时，而回答中的a moment ago 是一个明确的过去时间状语，应该用一般过去时。
5
过去分词的规则变化
动词过去分词的规则变化与动词过去式的规则变化相同。
① 一般情况下，在词尾直接加“ ed ”。
work---worked---worked visit---visited---visited
② 以“ e ”结尾的动词，只在词尾加“ d ”。live---lived---lived
③ 以“辅音字母+ y ”结尾的动词，将 "y" 变为 "i" ，再加“ ed ”。
study---studied---studied cry---cried---cried
④ 重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。stop---stopped---stopped drop---dropped--dropped

初中英语动词时态讲解及练习
16种英语时态总结归纳 时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。 英语时态分为16种：一般现在、一般过去、一般将来、过去将来时，以及这四者的进行时、完成时和完成进行时。 1. 一般现在时 用法：A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。C) 经常性、习惯性动作。 例：He always helps others. （他总是帮助别人。） D) 客观事实和普遍真理。尤其要注意，如果前后文不是一般现在时，则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作，（仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词）可以与表示未来时间的状语搭配使用。常见的用法是：飞机、火车、轮船、汽车等定期定点运行的交通方式。 例：The next train leaves at 3 o'clock this afternoon.（下一趟火车今天下午3点开车。） How often does this shuttle bus run? （这班车多久一趟？） F) 在时间和条件状语从句里经常用一般现在（有时也用现在完成时）表示将来事情。 例：When you have finished the report, I will have waited for about 3 hours.（等你完成这份报告的时候，我就已经等了将近3个小时了。） 2. 现在进行时(be doing) 用法：现在正在进行的动作。 3. 现在完成时(have done) 用法： A) 表示动作到现在为止已经完成或刚刚完成。 例：I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始，持续到现在的动作或情况，并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点，或for 加一段时间，或by加一个现在时间。 例：Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是：“虽然牛顿是个伟大的人物，但他的许多见解直到今天还在受到挑战，并且被现代科学家的工作所修正。”challenge是及物动词，在本句中应当是被动语态；其动作延续到今天，所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging都是主动语态，不可能是答案。B) may be challenged虽然是被动语态，但意思与全句内容不合，所以不对。 C) 表示发生在过去，但对现在仍有影响的动作或情况。通常用点动词，如：arrive, begin, find, give, lose等。 例：John has broken his left leg.（约翰摔断了左腿。） 注意事项 A) 现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于：现在完成时强调动作的动态，或受动态的影响，是动态的结果，对现在有影响；过去时只表示过去的某个具体时间里发生的动作，与现在没有联系。

时态 1. 一般现在时 ●形式：do does（单数第三人称） ●意义：一般现在时表示客观的、普遍性的真理以及经常性的事 件。 ●用法： A) 表示现在发生的动作、情况、状态和特征。 B) 经常性、习惯性动作。 e.g.：He always helps others. （他总是帮助别人。） He often goes to the gym. C) 客观事实和普遍真理。尤其要注意，如果前后文不是一般现 在时，则无法保持主句、从句时态一致。 e.g.: The sun rises in the east and sets in the west. Knowledge is power. ●这一用法场合一些表动作频率的时间副词连用： 1). 表示肯定的频率副词：always, frequently, usually, sometimes, generally, occasionally, often etc. 2). 表示否定的频率副词：never, seldom, rarely etc. ?这些副词的位置：在Be动词后，实义动词前。 e.g. He is always late. 2. 一般过去时 ●形式：did ●意义：一般过去时表示在过去的某一特定时间发生和结束的活 动或情况。 ●用法: A) 表示过去某个时间发生的动作或情况。 e.g.: I saw him in the library yesterday morning. （有特定的时间状语） ?y esterday, yesterday evening, last night/month/spring/year, the night before last（前天 晚上），three days/months/years ago, in 1999 etc.。这 些时间状语之前不用加介词。 B) 表示过去习惯性动作，一直持续或反复发生的动作，此时可与表示拼读的时间副词连用。
初中英语八大时态总结
初中英语八大时态总结 一、一般现在时 具体情况（主要用于下面几情况） 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 在这种情景中，句子常带有表示频率的时间状语：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等，以表示句中的动作或状态是习惯性的、经常性的。例如： They raise ducks as a sideline .他们以养鸭为副业。 It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。例如： He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 3) 陈述客观事实、客观真理。 顾名思义，客观的情况是"没有时间概念"的；也"不会在意动作进行的状态"。例如： The sun rises in the east .日出东方。 4) 根据英文语法规定，当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如： I'll tell him the news when he comes back. 他回来时，我将告诉他这个消息。 *【用于一般现在时的副词，除了上面提到的一些表示频率的以外，常见的还有：now, today , nowadays等等】 二、一般过去时 具体情况（主要用于下面几情况） 1.主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。 例：I was very thin in my childhood. 2.一般过去时由谓语动词的过去式表示，也就是说动词词末要加-ed（除不规则动词外）。常和一般过去时连用的过去时间状语有：last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 例：Did you meet yesterday? He left just now. 3.使用一般过去时，在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。"过去"的时间概念有两层意思：一是指"现在某个时间"以前的时间；二是指"说话、写文章的那个时间点"以前的时间 He got his driving license last month. 他上个月拿到了驾照。
