英語中虛擬語氣的具體句式和句型講解

壹、詞的語氣

指我們平常說的說話人說話的口氣。(在英語中,語氣除了指語調以外,最主要的是通過動詞發生變化而表示不同語氣)

英語中的語氣分為三類:

陳述語氣(用於陳述句、疑問句、感嘆句)

祈使語氣(用於祈使句)

虛擬語氣(用於條件狀語從句、賓語從句等)

[編輯本段]二、虛擬語氣

1) 虛擬語氣概念

虛擬語氣用來表示說話人的主觀願望或假想,所說的是壹個條件,不壹定是事實,或與事實相反。

2) 在條件句中的應用

條件句可分為兩類,壹類為真實條件句,壹類為非真實條件句。非真實條件句表示的是假設的或實際可能性不大的情況,故采用虛擬語氣。

[編輯本段]三、虛擬語氣在非真實條件狀語從句中的用法

1、真實條件狀語從句與非真實條件狀語從句

eg .

If he doesn’t hurry up, he will miss the bus. ( 真實條件狀語)(不是虛擬語氣)

If he was free, he would ask me to tell stories. (真實條件狀語)(不是虛擬語氣)

If I were you, I would go at once. (非真實條件狀語從句)

If there were no air, people would die. (非真實條件狀語從句)

總結就是 四個字:主將從現,主句用將來時,從句用壹般現在時。

2、虛擬語氣在非真實條件狀語從句中的用法及動詞形式

① 表示與現在事實相反的情況

(條件)從句謂語動詞形式 主句謂語動詞形式

謂語動詞用壹般過去式

(be用were) should/would/could/might+動詞原形(過去將來時)

eg.

If I were you, I would take an umbrella.如果我是妳,我會帶把傘。(事實:我不可能是妳)

If I knew his telephone number, I would tell you. 如果我知道他的電話號碼,我就會告訴妳。(事實:不知道)

If there were no air or water, there would be no living things on the earth. 如果沒有水和空氣,地球上就不會有生物。(事實:地球上既有空氣也有水)

If I had any money with me, I could lend you some. 如果我帶錢了,我就會借給妳些。(事實:沒帶錢)

If he studied harder, he might pass the exam.如果他在努力些,就能通過考試了。(事實:學習不用功)

②表示與過去事實相反的情況

從句謂語動詞形式 主句謂語動詞形式

Had+過去分詞(過去完成時) Should/would/could/might+

have+過去分詞(現在完成將來時)

eg. If I had got there earlier, I should/could have met her. 如果我早到那兒,我就會見到她。(事實:去晚了)

If he had taken my advice, he would not have made such a mistake. 如果他聽我的勸告的話,就不會犯這樣的錯誤了。(事實:沒有聽我的話)

③表示對將來情況的主觀推測(可能相反或可能性很小)

從句 主語 例句

If+主語+ ① should+動詞

(①通常與壹個表示時間狀語連用)其 中were to do可能性最小,

should/would/

could/might+動詞原形

c、表示將來難以實現的願望

②虛擬語氣用在suggest(建議)、insist(堅持)、demand(要求)、order(命令)等動詞後的賓語從句中。

在這種用法中,無論主句謂語動詞為何種時態,從句的謂語動詞都用:“should + 動詞原形”或只用“動詞原形”。

如 He suggested that we (should) take the teacher’s advice

He insisted that we (should) take the teacher’s advice
