㈠ 高一下學期英語語法
動詞的語氣——虛擬語氣(The Subjunctive Mood)
一、語氣的定義和種類
l、語氣:語氣是動詞的一種形式,它表示說話人對某一行為或事情的看法和態度。
2、語氣的種類:
(1)陳述語氣: 表示動作或狀態是現實的、確定的或符合事實的,用於陳述句、疑問句和某些感嘆句。如:We are not ready. 我們沒准備好。What a fine day it is!多好的天氣啊!
(2)祈使語氣: 表示說話人的建議、請求、邀請、命令等。如: Open the door, please。請打開門。
(3)虛擬語氣: 表示動作或狀態不是客觀存在的事實,而是說話人的主觀願望、假設或推測等。如: If I were you, I should study English. 如果我是你,我就學英語了。May you succeed! 祝您成功!
二、虛擬語氣在條件從句中的用法
條件句有兩類,一類是真實條件句,一類是虛擬條件句。如果假設的情況是有可能發生的,就是真實條件句。在這種真實條件句中的謂語用陳述語氣。如: If it doesn』t rain tomorrow, we will go to the park. 如果明天不下雨,我們就去公園。
如果假設的情況是過去或現在都不存在的,或將來不大可能發生的,則是虛擬條件句。如: If he had seen you yesterday, he would have asked you about it. 如果他昨天見到你,他會問你這件事的。(事實上他昨天沒見到你,因此也未能問你這件事。)
在含有虛擬條件句的復合句中,主句和從句的謂語都要用虛擬語氣。現將虛擬條件從句和主句的動詞形式列表如下:
與現在事實相反: 從句: 動詞的過去式(be的過去式一般用were)
主句:would/ should/ could/ might + 動詞原形
與過去事實相反 : 從句 :had + 過去分詞
主句 :would/ should/ could/ might + have + 過去分詞
與將來事實相反 : 從句:動詞過去式,should + 動詞原形,
主句 :were to + 動詞原形 would/ should/ could/ might + 動詞原形
注: 主句中的should只用於I、we,但在美國英語中,should常被would代替;從句中的should可用於各種人稱。
l、表示與現在事實相反的假設和結果。如: If my brother were here, everything would be all right. 要是我哥哥在這兒 ,一切都沒問題了。
2、表示與過去事實相反的假設和結果。如: If you had taken my advice,you wouldn't (couldn』t) have failed in the exam. 如果你按照我的建議去做,你一定不會(不可能)考試不及格。
3、表示與將來事實可能相反的假設和結果。如: If it were Sunday tomorrow, I should (would,could,might) go to see my grandmother. 如果明天是星期天,我就 (可能)去看望我奶 奶。If it were to snow this evening, they would not go out. 如果今晚下雪,他們將不出去了。
4、有時條件從句中的動作和主句中的動作發生的時間不一致(表示錯綜時間的虛擬語氣),這時動詞的形式要根據它所表示的時間加以調整。例如: If you had listened to the doctor, you would be all right now. 如果你當初聽了醫生的話,身體現在就好了。(從句動作指過去,主句動作指現在)
5、虛擬條件句可以轉換成下列形式:
(l)省略連詞if。在書面語中,如果虛擬條件從句中有were,had 或 should,可以把if省略,把這幾個詞放到主語之前,構成主謂倒裝。例如: Should he come (If he should come), tell him to ring me up. 他要是來了,讓他給我打個電話。Were I you (If I were you), I would not do it. 我要是你,就不做這事。
(2)用介詞短語代替條件狀語從句。有時假設的情況並不用條件從句表示出來,而是通過介詞短語來表示。如: Without air (If there were not air), there would be no living things. 如果沒有空氣的話,就不會有生物了。But for your help (If it hadn』t been for your help) I couldn』t have done it. 要是沒有你的幫助,我就不可能完成這件事。
假設的情況有時可以通過上下文或其他方式表現出來。如: I was busy that day. Otherwise I would have gone there with them. (If I hadn』t been busy that day, I would have gone there with them.) 我那天很忙,否則,我就和他們一起去那兒了。(如果我那天不忙的話,我就……);I would have finished the work, but I have been ill. (If I hadn』t been ill, I would have finished the work.) 我本來該完成這項工作的,但我生病了。(如果我沒生病的話,我就會完成……)
6、省去條件從句或主句:表示虛擬語氣的主句或從句有時可以省略,但其含義仍可以推知。
(1)省去條件從句。如: You could have washed your clothes yourself. 你本可以自已洗衣服的。省去了"If you had wanted to")(事實是:你自己沒洗衣服,因為你不想洗。)
(2)省去主句(常用以表示願望)。如: If my grandmother were with me! 如果我的祖母與我在一起多好啊!(事實是:祖母已不在世。);If only she had not left! 如果她沒走就好了!(事實是:她已經走了。)
三、虛擬語氣的其他用法
l、虛擬語氣在主語從句中的用法:在"It is important (strange,natural,necessary)that…"這類句型里,that所引導的主語從句中的謂語動詞常用 「should+動詞原形」結構,表示某事是"重要"、"奇怪"、"自然"、"必要"等意義。如: It is important that every member (should) inform himself of these rules. 重要的是每個成員知道這些規則。
2、虛擬語氣在賓語從句中用法:
(1)在動詞wish後的賓語從句中,表示與現在或過去的事實相反,或對將來的主觀願望,從句通常省略連詞that。1)表示對現在情況的虛擬:從句動詞用過去式或過去進行式(be動詞一般用were)。如: I wish I knew the answer to the question. 我希望知道這個問題的答案。(可惜不知道);2)表示對過去情況的虛擬:從句動詞常用"had+過去分詞"。如: I wish (wished) I hadn』t spent so much money. 我後悔不該花那麼多錢。(實際上已經花掉);3)表示對將來的主觀願望:謂語動詞形式為"would+動詞原形"。此時要注意,主句的主語與從句的主語不能相同,因為主句的主語所期望的從句動作能否實現,取決於從句主語的態度或意願(非動物名詞除外)。如: I wish it would stop raining. 但願雨能停止;I wish you would come soon. 但願你立刻來。
(2)在suggest,demand,order,propose,insist,command,request,desire等動詞後的賓語從句中,謂語動詞用「should + 動詞原形」,表示建議、要求、命令等。如: I demand that he (should) answer me immediately. 我要求他立刻答復我。
3、虛擬語氣在狀語從句中的用法
(1)在帶有even if/ even though引導的讓步狀語從句的主從復合句中,主句和從句都用虛擬語氣,動詞形式與含有非真實條件句的虛擬語氣相同。如: Even if he had been ill, he would have gone to his office. 即使生了病,他都去辦公室。
(2)由as if或as though引導的狀語從句表示比較或方式時。從句謂語形式為動詞的過去式(be用were)或 「had+過去分詞」。如: He treated me as if I were a stranger. 他那樣對待我,好像我是陌
生人似的。She talked about the film as if she had really seen it. 她談論那部影片,就好像她確實看過一樣。
注:如果表示的事情可能會發生,那麼方式狀語從句中的謂語動詞可用陳述語氣。
(3)在in order that或so that引導的目的狀語從句中,謂語動詞多用 「could或might(有時也用should)+ 動詞原形」。如: Mr green spoke slowly so that his students could (might) hear clearly. 格林先生說得很慢,好讓學生聽清楚。
4、虛擬語氣在定語從句中的用法:在"It is time (that) …"句型中,定語從句的謂語動詞常用虛擬語氣表示將來,動詞形式一般用過去式,意思是"該干某事的時候了"。如: It』s (high) time we did our homework. 我們該做作業了。
5、虛擬語氣在簡單句中的用法
(1)情態動詞的過去式用於現在時態時,表示說話人的謙虛、客氣、有禮貌,或委婉的語氣,常見於日常會話中。如: It would be better for you not to stay up too late. 你最好別太晚睡覺。
(2)在一些習慣表達中。如: I would rather not tell you. 我寧願不告訴你。
(3)用「may + 動詞原形」表示"祝願"、"但願」,此時may須置於句首(多用於正式文體中)。如:May you be happy!祝你快樂!May good luck be yours.祝你順利。

A. even, come B. even, have come C. ever, come D. ever, have come

Since 用來說明動作起始時間,for用來說明動作延續時間長度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:並非有for 作為時間狀語的句子都用現在完成時。
I worked here for more than twenty years. (我現在已不在這里工作。)
I have worked here for many years.(現在我仍在這里工作。)
注意:用句型轉換的方法,很容易排除非延續動詞在有for/since結構的完成時中的誤用。
1)(對) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(錯) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對,它應改為 Harry got married six years ago. 或 Harry has been married for six years.
返回動詞的時態目錄
11.13 since的四種用法

11.14 延續動詞與瞬間動詞
1) 用於完成時的區別
延續動詞表示經驗、經歷; 瞬間動詞表示行為的結果,不能與表示段的時間狀語連用。例如:
He has completed the work. 他已完成了那項工作。 (表結果)
I've known him since then. 我從那時起就認識他了。(表經歷)
2) 用於till / until從句的差異
延續動詞用於肯定句,表示"做……直到……" 瞬間動詞用於否定句,表示"到……,才……"。例如:
He didn't come back until ten o'clock. 他到10 點才回來。
He slept until ten o'clock. 他一直睡到10點。
典型例題
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本題後句強調對現在的影響,我知道她的模樣,你不用描述。再次,several times告知為反復發生的動作,因此用現在完成時。
2. ---I'm sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的動作由過去開始,持續到現在,應用現在完成時。

11.15 過去完成時
1) 概念:表示過去的過去
----|----------|--------|----> 其構成是had +過去分詞構成。
那時以前 那時 現在
2) 用法
a. 在told, said, knew, heard, thought等動詞後的賓語從句。例如:
She said (that)she had never been to Paris. 她告訴我她曾去過巴黎。
b. 狀語從句
在過去不同時間發生的兩個動作中,發生在先,用過去完成時;發生在後,用一般過去時。例如:
When the police arrived, the thieves had run away. 警察到達時,小偷們早就跑了。
c. 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…"。例如:
We had hoped that you would come, but you didn't. 那時我們希望你能來,但是你沒有來。
3) 過去完成時的時間狀語before, by, until , when, after, once, as soon as。例如:
He said that he had learned some English before. 他說過他以前學過一些英語。
By the time he was twelve, Edison had began to make a living by himself. 到了十二歲那年,愛迪生開始自己謀生。

A. had written, left B,were writing, has left C. had written, had left D. were writing, had left
答案D. "把書忘在辦公室"發生在"去取書"這一過去的動作之前,因此"忘了書"這一動作發生在過去的過去,用過去完成時。句中when表示的是時間的一點,表示在"同學們正忙於……"這一背景下,when所引導的動作發生。因此前一句應用過去進行時。
注意: had hardly… when 還沒等…… 就……。例如:
I had hardly opened the door when I he hit me. 我剛打開門,他就打了我。
had no sooner…than 剛…… 就……。例如:
He had no sooner bought the car than he sold it. 他剛買了這輛車,轉眼又賣了。
返回動詞的時態目錄
11.16 用一般過去時代替過去完成時

When she saw the mouse,she screamed. 她看到老鼠,就叫了起來。
My aunt gave me a hat and I lost it. 姑媽給了我一頂帽子,我把它丟了。
2 ) 兩個動作相繼發生,可用一般過去時;如第一個動作需要若干時間完成,用過去完成時。例如:
When I heard the news, I was very excited.
3) 敘述歷史事實,可不用過去完成時,而只用一般過去時。例如:
Our teacher told us that Columbus discovered America in 1492.
返回動詞的時態目錄
11.17 將來完成時

A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.

答案B.句中的as = when, while,意為"當……之時"。描述一件事發生的背景時,用過去進行;一個長動作發生的時候,另一個短動作發生。句意為 "在她看報紙時,奶奶睡著了。"句中的 fell(fall的過去時),是系動詞,後跟形容詞,如:fall sick。
