虛擬人稱代詞be動(dòng)詞,人稱代詞和be動(dòng)詞

1、人稱代詞與Be動(dòng)詞的縮寫形式（全部）

   I am=I‘m

you are=you’re

he is=he‘s

she is=she’s

we are=we‘re

they=they’re

it is=it‘s

2、虛擬語氣人稱代詞后be動(dòng)詞的形式

   是用 were

虛擬語氣在條件句中的用法：

主句時(shí)態(tài)：Should\would\could\mightdo（動(dòng)詞原形）

從句時(shí)態(tài)：過去式（be動(dòng)詞各人稱都用were）

例句：If I were you, I should \would make full use of my time to study.

主句時(shí)態(tài)：Should\would\could\mighthave done（動(dòng)詞過去分詞）

從句時(shí)態(tài)：Haddone(過去分詞)

例句：If you hade earlier, you would have met him.

主句時(shí)態(tài)： Should\would\could\mightdo（動(dòng)詞原形）

從句時(shí)態(tài)：（可以使用下列其中之一時(shí)態(tài)）

a. 過去式（be動(dòng)詞各人稱都用were）

b. should動(dòng)詞原形

c. were to 動(dòng)詞原形

例句：If it rained \should rain\were to rain tomorrow, the crops would be saved.

一般是用在

If I were you....

3、虛擬語氣中be動(dòng)詞的用法

   選were

表示與現(xiàn)在事實(shí)相反的情況：

從句：If 主語過去時(shí) 主句：主語should/would/could/mightdo

eg1．If I were you,I would take an （事實(shí)：我不可能是你） 2．If I knew his telephone number,I would tell .（事實(shí)：不知道）

這道題是與事實(shí)相反的,因?yàn)樗豢赡苁浅?所以填Were(Be動(dòng)詞的過去式在虛擬語氣里一般都用were)

、真實(shí)條件狀語從句與非真實(shí)條件狀語從句 eg . if he doesn’t hurry up, he will miss the bus. ( 真實(shí)條件狀語)（不是虛擬語氣） if he was free, he would ask me to tell stories. （真實(shí)條件狀語）（不是虛擬語氣） if i were you, i would go at once. （非真實(shí)條件狀語從句） if there were no air, people would die. （非真實(shí)條件狀語從句） 總結(jié)就是 四個(gè)字：主將從現(xiàn)，主句用將來時(shí)，從句用一般現(xiàn)在時(shí)。 2、虛擬語氣在非真實(shí)條件狀語從句中的用法及動(dòng)詞形式 ① 表示與現(xiàn)在事實(shí)相反的情況 （條件）從句謂語動(dòng)詞形式 主句謂語動(dòng)詞形式 謂語動(dòng)詞用一般過去式 （be用were） should/would/could/might動(dòng)詞原形（過去將來時(shí)） eg. if i were you, i would take an ，我會(huì)帶把傘。（事實(shí)：我不可能是你） if i knew his telephone number, i would tell you. 如果我知道他的，我就會(huì)告訴你。（事實(shí)：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(huì)有生物。(事實(shí)：地球上既有空氣也有水) if i had any money with me, i could lend you me. 如果我?guī)уX了，我就會(huì)借給你些。（事實(shí)：沒帶錢） if he studied harder, he might pass the ，就能通過考試了。（事實(shí)：學(xué)習(xí)不用功） ②表示與過去事實(shí)相反的情況 從句謂語動(dòng)詞形式 主句謂語動(dòng)詞形式 had過去分詞（過去完成時(shí)） should/would/could/might have過去分詞（現(xiàn)在完成將來時(shí)）（過去將來完成時(shí)） eg. if i had got there earlier, i should/could have met her. 如果我早到那兒，我就會(huì)見到她。（事實(shí)：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(huì)犯這樣的錯(cuò)誤了。（事實(shí)：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?。?從句謂語動(dòng)詞形式 主句謂語動(dòng)詞形式 if主語 ① should動(dòng)詞 ② did ③were to do (①通常與一個(gè)表示時(shí)間狀語連用)其 中were to do可能性最小， should/would/ could/might動(dòng)詞原形 he woulde here tomorrow, i should/would talk to him. 如果他哪天來這兒的話，我就跟他談?wù)?。（事?shí)：來的可能性很?。?if there were a heavy snow next sunday, we would not go skating. 如果下周日下大雪，我們就不能去滑冰了。（事實(shí)：不知能否下雪） if she were to be there next monday, i would tell her about the matter. 如果她下周一來這兒的話，我就會(huì)告訴她這件事得始末。 在表示建議、命令、要等含義的賓語從句，謂語動(dòng)詞常用虛擬語氣，"should＋動(dòng)詞原形"構(gòu)成，should 可省略。

4、be 在虛擬語氣中的用法

   虛擬語氣在條件句中用法 一 與現(xiàn)在事實(shí)相反 主句時(shí)態(tài)是情態(tài)動(dòng)詞加動(dòng)詞原形 從句時(shí)態(tài)是過去時(shí)〈be在句中一般都改為were〉二 與將來事實(shí)相反 主句時(shí)態(tài)是情態(tài)動(dòng)詞加動(dòng)詞原形 從句時(shí)態(tài)是過去時(shí)＜BE在句中都用were>;should/ were to動(dòng)詞原形

5、虛擬語氣中be動(dòng)詞怎樣變化??？

   用were ,但遇到第一人稱主語是可以用was

以前是的，但現(xiàn)在有時(shí)可見到was的情況。你所給的句子中兩空應(yīng)分別填were, would make

有三種可能性：

1. were , would make 與現(xiàn)在事實(shí)相反

2. had been , would have made 與過去事實(shí)相反

3. were to / should , would make 與將來事實(shí)相反

是可以變成were,但你那舉例是錯(cuò)誤的，這樣變只適合If I were you,I…因?yàn)槲矣肋h(yuǎn)不可能是你，這才是虛擬，變成were。

虛擬語氣中be只能用were,后面那個(gè)空應(yīng)該填would make 是與現(xiàn)在事實(shí)相反

6、表示虛擬的時(shí)候，be動(dòng)詞用法.

   教材和語法書一般用Were 口語有時(shí)候用Was反正考試時(shí)用Were一般都沒錯(cuò)，嘻嘻
