虚拟人称代词be动词,人称代词和be动词

1、人称代词与Be动词的缩写形式（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、虚拟语气人称代词后be动词的形式

   是用 were

虚拟语气在条件句中的用法：

主句时态：Should\would\could\mightdo（动词原形）

从句时态：过去式（be动词各人称都用were）

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

主句时态：Should\would\could\mighthave done（动词过去分词）

从句时态：Haddone(过去分词)

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

主句时态： Should\would\could\mightdo（动词原形）

从句时态：（可以使用下列其中之一时态）

a. 过去式（be动词各人称都用were）

b. should动词原形

c. were to 动词原形

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、虚拟语气中be动词的用法

   选were

表示与现在事实相反的情况：

从句：If 主语过去时 主句：主语should/would/could/mightdo

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

这道题是与事实相反的,因为他不可能是超人,所以填Were(Be动词的过去式在虚拟语气里一般都用were)

、真实条件状语从句与非真实条件状语从句 eg . if he doesn’t hurry up, he will miss the bus. ( 真实条件状语)（不是虚拟语气） if he was free, he would ask me to tell stories. （真实条件状语）（不是虚拟语气） if i were you, i would go at once. （非真实条件状语从句） if there were no air, people would die. （非真实条件状语从句） 总结就是 四个字：主将从现，主句用将来时，从句用一般现在时。 2、虚拟语气在非真实条件状语从句中的用法及动词形式 ① 表示与现在事实相反的情况 （条件）从句谓语动词形式 主句谓语动词形式 谓语动词用一般过去式 （be用were） should/would/could/might动词原形（过去将来时） eg. if i were you, i would take an ，我会带把伞。（事实：我不可能是你） if i knew his telephone number, i would tell you. 如果我知道他的，我就会告诉你。（事实：不知道） if there were no air or water, there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水) if i had any money with me, i could lend you me. 如果我带钱了，我就会借给你些。（事实：没带钱） if he studied harder, he might pass the ，就能通过考试了。（事实：学习不用功） ②表示与过去事实相反的情况 从句谓语动词形式 主句谓语动词形式 had过去分词（过去完成时） should/would/could/might have过去分词（现在完成将来时）（过去将来完成时） eg. if i had got there earlier, i should/could have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） if he had taken my advice, he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话） ③表示对将来情况的主观推测（可能相反或可能性很小） 从句谓语动词形式 主句谓语动词形式 if主语 ① should动词 ② did ③were to do (①通常与一个表示时间状语连用)其 中were to do可能性最小， should/would/ could/might动词原形 he woulde here tomorrow, i should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。（事实：来的可能性很小） if there were a heavy snow next sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。（事实：不知能否下雪） if she were to be there next monday, i would tell her about the matter. 如果她下周一来这儿的话，我就会告诉她这件事得始末。 在表示建议、命令、要等含义的宾语从句，谓语动词常用虚拟语气，"should＋动词原形"构成，should 可省略。

4、be 在虚拟语气中的用法

   虚拟语气在条件句中用法 一 与现在事实相反 主句时态是情态动词加动词原形 从句时态是过去时〈be在句中一般都改为were〉二 与将来事实相反 主句时态是情态动词加动词原形 从句时态是过去时＜BE在句中都用were>;should/ were to动词原形

5、虚拟语气中be动词怎样变化啊？

   用were ,但遇到第一人称主语是可以用was

以前是的，但现在有时可见到was的情况。你所给的句子中两空应分别填were, would make

有三种可能性：

1. were , would make 与现在事实相反

2. had been , would have made 与过去事实相反

3. were to / should , would make 与将来事实相反

是可以变成were,但你那举例是错误的，这样变只适合If I were you,I…因为我永远不可能是你，这才是虚拟，变成were。

虚拟语气中be只能用were,后面那个空应该填would make 是与现在事实相反

6、表示虚拟的时候，be动词用法.

   教材和语法书一般用Were 口语有时候用Was反正考试时用Were一般都没错，嘻嘻
