【正文】 I was about to tell him about it when Wu Dong got ，吳東進來了。如：The conference was going to be held the next 。Even after the lecture ended, the audience would not ，聽眾仍不肯離去。C)No matter how difficult the work was , he would keep on doing it until he acplished ，他總會堅持不懈地把它干完。B)During that period , he would do morningexercises every ，他每天早鍛煉。He didn39。例如：A)When I thought about it , I wondered what their reaction would ，我想知道他們的反應是什么。這個狀語或是一個短語，或是一個句子。但這個“將來”時間絕不會延伸到“現(xiàn)在”；而僅限于“過去時間區(qū)域內”。I said I would arrange ?！?過去將來時由would, was/were going to, was/were to was/were about to等加動詞原形構成, 也可由was/were on the point of加動名詞構成。(5)It’s [will be] the first time that?(第一次?)：It’s the first time I’ve e 。(4)up to [until] now(到現(xiàn)在為止)：Up to now, the work has been 。I have been here(for)the last [past] 。We haven’t had any trouble so ，我們還沒有遇到任何麻煩。(指從星期二至昨天未吃東西)③ 表示時間長度時，通常用一般現(xiàn)在時代替現(xiàn)在完成時：It’s ten years since he left 。Where have you been since I last saw? 自我上次見到你之后你到哪里去了?【注】有時可用其他時態(tài)的情況，但須注意：① 對于某些表示狀態(tài)的動詞(如 seem 等)，或因語義等方面的原因，有時可能用一般現(xiàn)在時比較現(xiàn)在完成時更合適：It seems like years since we last 。在這種情況下，應該用“It has been ? ；since?”的句式來表達。但是可以用before 來表示“以前”的意義，因為它只表示“以前”，而不知什么時候的以前。You are not being 。例如：Tom is being a good boy 。這類動詞常見的有：be , believe , consist , find , forget , hate , have , hope , hear , know , like , love , notice , prefer , remember , see , seem , smell , suggest , taste , understand , want , wish , sit down , stand up 等等。）2）在含有時間狀語從句或條件狀語從句的主從復合句中，如果主句的謂語動詞是一般將來時，那么從句的謂語動詞就只能用一般現(xiàn)在時來表示將來時；如果主句的謂語動詞是過去將來時，那么從句的謂語動詞就只能用一般過去時來表示過去將來時。）He has spoken English for three years since he came to the USA.（現(xiàn)在完成時，這里說明動作的總和。）He spoke English when he was in New Zealand.（一般過去時，說明動作發(fā)生的時間。幾點注意1)一個句子應該用什么時態(tài)只能取決于它需要表達的意思，以及它所處的語言環(huán)境。So far we39。3）表示過去發(fā)生的動作持續(xù)到現(xiàn)在，并可能還要延續(xù)It has been five years since he joined the 。2）表示發(fā)生在過去而對現(xiàn)在產(chǎn)生影響、帶來結果的動作Have you had your dinner? 你吃晚飯了嗎？She has been to the United 。t met for many 。She has read 150 pages 。弄清了這一區(qū)別，就很容易理解現(xiàn)在完成時了。其實不然，現(xiàn)在完成時主要表示，發(fā)生在過去的動作延續(xù)到現(xiàn)在剛剛完成、或許還要延續(xù)；側重于這個動作對現(xiàn)在帶來的結果、產(chǎn)生的影響、積累的總和等等。對于初接觸現(xiàn)在完成時的人來說，往往會產(chǎn)生一種茫然，因為它似乎與一般過去時相似。)Have you seen my bag? 你看到我的手提包了嗎?(你知道它在哪里?)She has been a dancer for ten 。例句：I have seen the film 。We had hoped that you would e to see us, but you didn’，但你沒有來。如：He entered the room, turned on the light and read an evening (had)called her before I left the ，通常連用的動詞是 want, think, hope, plan, mean, expect, intend, suppose 等：I had meant to e, but something ，但有事就沒有來。試比較：They had arrived at the station by ten arrived at the station at ten ，謂語動詞動作發(fā)生的時間先后須依據(jù)上下文來判斷：先發(fā)生的用過去完成時，后發(fā)生的則用一般過去時。John returned home 。I39。試比較：I have learned 1000 English words so 1000 個英語單詞。如：Before she came to China, Grace had taught English in a middle school for about five had collected more than 300 Chinese stamps by the time he was ，一直延續(xù)到這一過去時間，而且動作尚未結束，仍然有繼續(xù)下去的可能。如：He told me that he had written a new book.(had written 發(fā)生在 told 之前)，它不能離開過去時間而獨立存在。如：When I woke up, it had stopped ，雨已經(jīng)停了。I met Wang Tao in the street hadn39。如：Where did you study before you came here?After he closed the door, he left the classroom.（3）表示意向的動詞，如hope, wish, expect, think, intend, mean, suppose等，用過去完成時表示“原本?，未能?”We had hoped that you would e, but you didn39。如：She said that she had seen the film before.（2）狀語從句中在時間、條件、原因、方式等狀語從句中，主、從句的動作發(fā)生有先后關系，動作在前的，要用過去完成時，動作在后的要用一般過去時。這種用法常出現(xiàn)在：（1）賓語從句中當賓語從句的主句為一般過去時，且從句的動作先于主句的動作時，從句要用過去完成時。如： They had planted six hundred trees before last “過去的過去”來判定。clock last night.（2）by the end of + 過去的時間點。與過去完成時連用的時間狀語有：（1）by + 過去的時間點。|||那時以前 那時 現(xiàn)在構成：過去完成時由“助動詞 had + 過去分詞”構成，其中 had 通用于各種人稱。By the time he was twelve, Edison had begun to make a living by ，愛迪生開始自己謀生。例句：She said she had never been to 。How much did you want to spend, sir? 先生，您打算花多少錢？注：一般過去時也有類似用法，但比較而言，用過去進行時顯得更客氣，更不肯定。如：I was wondering if you could give me a 。s getting ，我們離開了那兒。My friend said to me that he was lunching with one of his customers that ，他今天要與他的一位客戶一塊兒吃午飯。例如：When National Day was ing near , they began to make a plan for the ，他們開始制訂度假計劃。例如：One night, he was typing in his , a man broke into his house and cut off the electricity ?.一天晚上，他正在書房里打字。What were you doing at eight last night ? 昨晚八點鐘你在做什么？2）用于故事的開頭，交代故事發(fā)生的背景情況。過去進行時主要用于下面的情景中：1）表示在過去某時刻正在進行的動作，例如：At this moment yesterday, I was packing for ，我正在收拾東西去露營。這個狀語可能是短語，詞組，或是一個從句。What t
