现在完成时讲解与练习 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 have't seen her for four years. 我有四年没见到她了。 3．结构 1）．陈述句结构：主语＋have( has)（not）+过去分词＋其它。have not=h aven’t has not=hasn’t. 2）．一般疑问句结构：Have( Has )＋主语＋过去分词＋其它 3）．特殊疑问句：特殊疑问词＋have(has) +主语+ 过去分词＋其它 eg. He has already finished his homework. He hasn’t finished his homework yet. Has he finished his homework yet --Yes, he has./ No, he hasn’t./ No, not yet. （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。 4.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。 He has been there three times the last few years.近几年他去过那里三次了。 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.今天你见过他吗我没有。 How many times have you been there this year 今年你去过那里多少次 （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.他参军三年了。
2020届高考英语二轮复习语法填空提升练习动词的时态、语态和主谓 一致 一、在空白处填入括号内单词的正确形式： 1. Since the United Nations declared June 21 the International Day of Yoga in 2014 , many cities in China_______(start)hosting international yoga festivals. 【答案】(现在完成时）have started 【解析】句意：自从联合国在2014年宣布6月21日为国际瑜伽日以来，中国的许多城市已经开始举办国际瑜伽节。此处since(自从……以来）引导时间状语从句，从句用一般过去时，主句用现在完成时，句子主语cities是复数形式，所以谓语动词也用复数形式。 2. Over the past decade, a global push to reduce hunger and extreme poverty______(mark) some significant successes. 【答案】(现在完成时）has marked 【解析】由时间状语Over the past decade可知，句子表示过去发生的动作对现在造成的影响，故用现在完成时，主语a global push是第三人称单数，谓语动词也用单数形式。 3 . The twins , who _______ ( finish ) their homework , were allowed to play badminton in the playground. 【答案】(过去完成时）had finished 【解析】此处表示这对双胞胎完成作业是在被允许到操场上打羽毛球（过去式）之前，所以完成作业应该使用过去完成时。 4. It is the first time that I______(punish) students. 【答案】(现在完成时）have punished 【解析】考查固定句型中的时态：It/This/That is the first time that sb. has done sth. ;It/This/That was the first time that sb. had done sth.。 5.While _________(pick) the tea, he received the news of his mother being ill ,so he carelessly put the leaves in his right sleeve and _______(leave) Hangzhou for Beijing 【答案】(现在分词）picking;(一般过去时）left 【解析】句意：在摘茶叶的时候，他收到了母亲生病的消息，所以他不小心把叶子放在他右边的袖子里，离开杭州去了北京。第一空所在句省略的主语he和pick之间是主谓关系，所以用现在分词。第二空，由and 可知此处与put是并列谓语，故填left。

(我们昨天没迟到) 疑问句：Was (Were) +主语+宾语 如： Were you ill yesterday? （你昨天病了吗？） 肯定回答： Yes, I was. (是的，我病了。) 否定句： No, I wasn't. (不，我没病。) 特殊疑问句：特殊疑问词+was (were) +主语+宾语 如：When were you born? 你是什么时候出生的？ 2.实意动词 肯定句：主语+ 动词过去式 + 宾语… She swam in the river yesterday afternoon . 否定句：主语+didn’t + 动词原形 +宾语… She didn’t swim in the river yesterday afternoon . 疑问句：Did +主语 +动词原形 + 宾语… ?

我妈妈昨天去购物了。 His uncle worked in Beijing in 2014. 他叔叔2014年在北京工作。 三、一般过去时的句式
语法探知：现在完成时态 一、掌握结构：助动词have/has + 动词的过去分词 二、掌握用法： 1.表示过去发生的某一动作对现在造成的影响或结果，常与一些时间状语，如:already, yet, ever, never, just, before, once, twice （次数）等连用，也可以和包括现在在内的时间状语，如these days, today, recently, this year, so far(=by now)等连用. e.g. I have already posted the letter. (信已经不在我这儿了) 2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段，since+时间点/从句, in(during) the last(past) ten years等，谓语只可用延续性动词。 我们知道英语动词根据词义可分为两种,一种是延续性的，一种是终止性的，终止性动词(也可称为非延续性动词,瞬间动词,或短暂性动词),如begin, start, die, buy, leave, come等,表示动作在一瞬间之内就能完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+段时间，since+点时间/从句连用,也不能用在how long引导的特殊疑问句中。（但在否定句中短暂性动词可以与for和since短语连用。） 如：They’ve left London for five days. (×) They’ve been away from London for five days. (√) 三、掌握短暂性动词如何转换成延续性动词 常见短暂性动词与延续性动词的对应关系如下: come/go/arrive/get/reach/move—be in/at open—be open die—be dead close—be closed become—be borrow—keep begin/start—be on put on—wear leave—-be away (from) buy—have fall asleep(ill)—be asleep(ill) end/finish—-be over catch a cold—have a cold join the army—be in the army/ be a soldier join the Party—be in the Party/ be a Party member get to do —do (get to know—know) get married —be married get up —be up begin to do —do (begin to study—study)
