初中英语现在完成时详解
现在完成时 一、现在完成时构成 构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。第三人称单数用has，其余用have. 现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例，其否定式、疑问式和简单回答形式如下： 1、现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。 My daughter has just gone out. 我女儿刚出去。 I’m sure we’ve met before. 我肯定我们以前见过面。 She has arrived. 她到了。 2、表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently, already, just, lately, for…, since…,yet等。如： I haven’t heard from her these days. 这些日子我没有收到她的信。 We haven’t seen you recently. 最近我们没有见到你。 They have been away for two years. 他们离开已经两年了。 She has been with us since Monday.
①for+时段 ②since+过去一个时间点（译为：自从……以来） ③since+时段+ago ④since+从句（过去时） ⑤It is+时段+since+从句（过去时） Mary has been ill?for three days. I have lived here?since 1998. 注意： since和for的区别 since后接时间点，如1993，last term, yesterday, the time I got there for后接一段时间，表示“长达多久”，如ten years, a while, two days等。3、表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等，在完成时当中不能和表示一段时间的状语连用，因为它们表示的动作不可能持续。因此，不能说： He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 4、has gone (to),has been (to), has been (in)?的区别 Have/Has gone(to) :去了(现在不在说话现场，可能在路上和已经到) Where is your father?He has gone to Shanghai. Have/Has been (to) :去过（已不在去过的地方） My father has been to Shanghai. Have/has been in：呆了多久（还在所呆的地方） My father has been in Shanghai?for two months. /since two months ago. 5、现在完成时不能和表示过去的时间状语连用，如yesterday, last year, in 1976, two days ago, just now, when I came in，但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。不能与when连用。

英语语法完成时篇
完成时篇（一）——现在完成时 [提问] 请问在句子“Working in London has been the best decision I have made so far. （Experiencing English Integrated Book1 Page71）”中，为什么时间状语是完成时的情况下，主句仍然可以使用现在完成时呢？ 答：完成时态通常表示已完成或已经开始从事的动作，它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。根据定义我们可以了解到，除了表示到现在为止动作已经完成或已经开始以外，还有多种情况可以用现在完成时来表达。 一、动作从过去某个时间开始发生，延续到现在，并且说话前已经完成。 例如：The mission has been carried out well.任务已经很好地完成了。 Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。 二、某个动作或状态发生在过去，持续并影响现在，有可能会继续保持下去。 例如：My brother has been abroad for several years.我哥哥已经出国好几年了。 It has rained all morning.雨下了一个早晨。 Up to now, parents have accepted the pop music youths prefer to.现在，家长们 已经接受了年轻人喜欢的流行音乐。 I have known him since the summer in 2001.自2001年的那个夏天，我就认识他了。 三、动作发生在现在之前的某个时间，可能是多次动作的集合，也表示习惯性的动作或 状态。 例如：Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。 Which countries have you traveled recently?最近你都去过那些国家？ How many papers have you read today? 你今天看了几篇论文？ 四、动作过去曾发生过一次或多次，也可能是一种经历。 例如：Students are very pride that the president has once visited their school. 学生们为总统曾访问过他们学校而骄傲。 Accidents like this have happened more than 20 times these years.这几年此类事故发生不下20起。 在现在完成时态的句子中，常伴随的时间状语有：already，yet，ever，never，just，before，lately，recently，till/until，always，now，since，today; in past years，all morning，all one’s life，up to now，these days，this week/month/year，for a long time。 现在完成时中有几点语法点要注意的： 1）for引出的时间状语只能修饰表示延续性动作的动词。不能用来修饰表示瞬间、短 暂动作或位置转移的动词。如John has come to China for three years，此句错误，come这个动作是短暂性动词，不可能持续发生，因此可改为John has been in China for three years，约翰已经爱中国生活了3年。短暂性动词有appear, begin，borrow，buy，come，close，die，fall，find，finish，join，kill，leave，lend，lose，see，start，stop。 2）在表示时间或条件的状语从句可以用现在完成时表示将来完成的动作。 例如：He will not quit my job until his parents have permitted.父母允许后他才会辞职。 I will arrive at 6 o’clock if the car h as been prepared then.如果到时车准备好了，我能在6 点到达。 3）It is the first/second time that…这个结构中，that从句要用现在完成时。 例如：It is the first time that I have heard of his deeds.这是我第一次听说他的事迹。

现在完成时语法
（Present Perfect）。 第一部分 现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态。学习现在完成时,先从结构和句式开始: 构成:主语 + have/has + 过去分词 + 其他。(当主语是第三人称单数时用has,其余人称用have。过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。) 否定式:主语+ haven't/hasn't + 过去分词+ 其他。 疑问式: Have /Has + 主语+ 过去分词+ 其他? 简略答语: Yes, 主语+ have/has.(肯定) No, 主语+ haven't/hasn't.(否定) 现在完成时常用的时间状语有： already （”已经”用于肯定句的中间和末尾处） never (“从不”用于中间处) ever （”曾经”用于疑问句和肯定句的中间处） just (“刚刚”用于中间处) yet (“已经”用于疑问句的末尾处/ “还”用于否定句的末尾处) 或不加任何的时间状语，但不能和表示过去的时间状语连用. 第二部分 现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志 already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。 He has already got her help. 他已得到她的帮助。 He has just seen the film. 他刚刚看过这场电影。 He hasn't come back yet. 他还没有回来。 * 以ever和never为标志 ever和never 表示到现在为止动作或状态曾经或从来没有发生过。 This is the best film I have ever seen. 这是我曾经看过的最好的一部电影。 He has never been to Beijing. 他从没有到过北京。 * 以动作发生的次数为标志 若某一动作到现在为止已经发生了若干次,则要使用现在完成时。 He says he has been to the USA three times. 他说他已经去过美国三次了。 * 以so far为标志 so far往往表示到目前为止动作或状态已经发生。 He has got to Beijing so far. 到目前为止他已到了北京。 She has passed the examso far. 到目前为止她已经通过了。 第三部分 过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。 *“终止”、“延续”要转换
