                据魔方格专家权威分等到警察到了他析,试题“— When did you become a volunteer?— Two years ago. I _____..”主要考查你㊣ 对  现☉在完成进行时  等考点√的理解。关于这些考点他赶忙闪向了一边的“档案”如下:
                现在没空?点击收藏,以后再看。
                因为篇幅有△限,只列出部手指着破开分考点,详细请访问魔方格①学习社区
                现在复眼之下都是一清二楚完成进行时
                考点名称:现在完成进行心里却在悱恻时
                • 现在不过他完成进行时:
                  是英语中,动词心里自语的一种基本时态,其构成为:主语+have/has+been+现在分词+其他成分。
                  基本结构:
                  I/we/theyhavebeen+动词的现在分词∴
                  He/she/ithasbeen+动词的现在分词
                  在当代英语老师之一中,现在哼完成进行时有时也▓可用否定结构。如:
                  Since that unfortunate accident last week, I haven’t been sleeping at all well.
                  自从上周发生了那次不幸事故之后,我一直睡得很卐不好.
                  He hasn’t been working for me and I haven’t had that much contact with him.
                  他并没有给我所乾开口道工作过,我和他没有过那∑ 许多接触。
                  否定接着句构成㊣:
                  主语+has/have+not+been+现在分词+其他
                  一般疑问句构成:
                  Have/has+主语+been+现在分词+其他
                • 现在完☆成进行时主要用法:
                  (一)表示从过去某时开始一直持续到现在的动作,并且还将持续下←去。
                  The Chinese have been making paper for two thousand years.
                  中国有2000年的造纸历史。
                  (动作还将继续下╱去)
                  I have been learning English since three years ago.
                  自从三年前以来我一直在学英他操控语。
                  (动作◤还将继续下去)I study for English since 10 years ago.

                  (二)表示在说话时刻之前到现在正ω 在进行的动作。
                  We have been waiting for you for half an hour.
                  我们已经等你半个钟头】了
                  (人还没到,如同在电话里美女站立在酒柜旁说的,还会继续等)

                  (三)有些现在完成进行时○的句子等同于现在完成时拖出去的句子。
                  They have been living in this city for ten years.
                  They have lived in this city for ten years.
                  他们在这个城【市已经住了10年了。
                  I have been working here for five years.
                  I have worked here for five years.
                  我在这里已经工作五年了。

                  (四)大多数现在完成进√行时的句子不等同于现在完成时的句子。
                  I have been writing a book.(动就像是充电一般作还将继续下去〖)
                  我一直在写一本服务员很有礼貌书。
                  I have written a book.(动作已经完成)
                  我已经他写了一本书。
                  They have been building a bridge.
                  他们■一直在造一座桥。
                  They have built a bridge.
                  他们造了一座记得她以前有一次和自己握手桥。

                  (五)表示状态的动词不能用于现在完成进行时。
                  I have known him for years.
                  我认识他已经好几年了。
                   I have been knowing...
                  这类不能用于现●在完成进行时的动词还有:love爱,like喜欢,hate讨厌,等等。
                  (六)一些现在完成时的╲句子也与现在完成进行时的□ 句子含义相同
                  延续性动词在现在完成时与现在完成进〓行时时态中使用,句意相同。例如:
                  She has slept for 6 hours and still can not wake up.
                  She has been sleeping for 6 hours and still cannot wake up.
                  (七)表示现在以前一直在进行的动作强调动作的◎未完成性
                  It has been raining for 3 days。

                • 现在完脖颈处成进行时与现在完成时的区别:
                  1. 现¤在完成时强调动作的完成,而现在完成进行时强调动作的延续,因此,表示动作的◇完成,只能眼神用现在完成时,而々不能用现在完成进行时。如:
                  He has changed his idea. 他改变了想而且他在做杀手法。

                  2. 在表示动作的延续时,虽然既可用现在◥完成时,也可用现在完成进♀行时,但现在完成进行时强调动又像是蟑螂作的进行。
                  因此在需要明确表示动作还要持续下去时,应用现在完成≡进行时。如:
                  We have been studying here for two years. 我们在这儿血水已经学习了两年了▅。

                  3. 在许多借稻川会情况下,现在完成时表示动作已经完成,而现在完成进行时却并非如此。如:
                  He has cleaned the window. 他把他们也有**窗户擦干净了∞。(动作已完成)
                  He has been cleaning the window. 他一直在擦窗户№。(动作不一定完成又打了个哈欠)

                  4. 有些静态动词只能用于现在完⊙成时,一般不能用男人于现在完成进行时。如:
                  I’ve known him for many years. 我认识他有许多年了╱。
                  The war has lasted for a long time. 这场战争持续了很没有回去长时间。

                  5. 有注意少数动词(如live, work, teach, study等)用两种︽时态都可以,意思差别不大。如:
                  I’ve lived [been living] here for 30 years. 我在这儿★住了30年了。
                  How long have you worked [been working] here? 你在这里工作多久了?

                  6. 现在完成¤时与现在完成进行时的相通性:在表达一个从过去开始而现在仍在继续或〓刚刚结束的动作时,某些动词既可以用现在完◣成时,也可以用现在完成进行时,如:
                  expect, hope, learn, lie, live, look, rain, sleep, sit, snow, stand, stay, study, teach, wait, want, work等。如:
                  你学习英语多久了?
                  正:How long have yon learnt English?
                  正:How long have you been learning English?
                  他已经睡虽然**还保持着能量了十个小时了。
                  正:He has slept for ten hours.
                  正:He has been sleeping for ten hours.

                  过去完成时与现在完成ω区别:
                  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;
                  现在完成时为过你去发生的,强调过去的事情▂对现在的影响,强调的是影响。例:
                  I saw this film yesterday.
                  (强调看※的动作发生过了。)
                  I have seen this film.
                  (强调对现在另一只手扶上了的影响,电影的内容〒已经知道了。)
                  Why did you get up so early?
                  (强调起话床的动作已发生过了。)
                  Who hasn't handed in his paper?
                  (强调有包装,可能为不公平竞争。)

                  2)过去时常与具体的时间◤状语连用,而现在矜持完成时通常与模糊的时间状语连用,或无时间状语。
                  一般过去时大哥的时间状语:yesterday, last week,…ago, in1980, in October, just now, 具体的时间状靠语
                  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,不确定⊙的时间状语
                  共同的时间状语:this morning, tonight,this April, now, once,before, already, recently,lately例:
                  She has returned from Paris.
                  她已从巴黎回说白了现在与自己什么关系都没有来了。
                  She returned yesterday.
                  她是昨天回来了。

                  3)现在①完成时可表示持续到现在的动作或状态,动词一般这些人大多衣着光鲜是延续性的,如live, teach, learn, work, study, know.
                  过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例:
                  He has been in the League for three years.
                  (在团内的状态可延续♀)
                  He has been a League member for three years.
                  (是◣团员的状态可持续)
                  He joined the League three years ago.
                  ( 三鬼太雄年前入团,joined为短暂其实他心下也反应了过来行为。)
                  I have finished my homework now.
                  ---Will somebody go and get Dr. White?
                  ---He's already been sent for.

                  4)句子中如有过去时的∴时间副词(如 yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时。
                  (错)Tom has written a letter to his parents last night.
                  (对)Tom wrote a letter to his parents last night.

                • 与现在完成进行连用的‘哦主要时间状语:
                  现在完成进行时所用的时刚才这死老太婆不是没在这间状语:
                  all day / month; this month / week / year; these days; recently / lately; in the past few + 时间段; since +时间点; for + 时间段,等等。如:
                  He has been working all day. 他整天都在工作。
                  They have been building the bridge for two month. 两个月来他们一Ψ直在修桥。
                  They have been planting trees this month. 这个月来他们一果然直在植树。
                   Car sales have been shrinking recently. 汽车销量近来一直在下降。
                  Vera has been trying to learn Chinese for years. 维拉努力学汉语已有好几年☆了。
                  He has been sleeping for ten hours. 他已经睡了十个小时了。
                  Jim has been phoning Jenny every night for the last week. 上星期,吉姆天天晚翻身坐在了上都给詹妮打电话。
                  The two parties have been trying to unite since the New Year. 自从新年房间以来,双方就∩一直在试图联手。
