English|虚拟语气和条件状语从句

虚拟语气在英语中,还是有一定地位的,毕竟大家都做着我有一百万的梦~~~

前言

目前所有的文章思想格式都是:知识+情感。
知识:对于所有的知识点的描述。力求不含任何的自我感情色彩。
情感:用我自己的方式,解读知识点。力求通俗易懂,完美透析知识。

正文

条件状语从句包含真实条件状语从句和虚拟语气。

真实条件状语从句

条件状语从句最常用的连接副词

1.if(如果.....)
if 后面可以加上 then,如果then省略了,也隐含在句子的意思里。
1)表示客观事实,主句用一般现在时或现在进行时,从句用一般现在时。(主现从现)
eg: If I eat too much, I feel uncomfortable.

2)表示将来可能发生的事的情况,主句一般将来时,从句要用一般现在时,此时主句的will表示肯定或很可能发生的事情。(真实的情况,而且主句用的一般将来时,表示这是预测。主将从现)
eg: If you park your car in the wrong place, a traffic pliceman will soon find it.

3)如果在条件状语从句中出现了will,不是将来时,而是表示意愿。
eg: If I will prepare, my chance will come someday.

unless (除非.....)

eg: All dreams are of no value unless they are followed by action.

其他比较常用的连接副词

suppose/supposing (that)
on condition that
so long as/ as long as
eg: Suppose you make some mistakes, it's not the end of the world.

only if(只有....才) 与 if only (只要.....就)

eg: Only if I get a job will I have enough money to go to school.

eg: The Almight has given men arms long enough to reach the stars if only they would put them out.

虚拟语气

虚拟语气的常规用法

1.什么叫虚拟语气?
答:就是不可能发生的情况的假设。
(汉语的虚拟语气通过语境实现,英语中的虚拟语气通过谓语动词的变化实现。)

2.现在虚拟语气-一般过去时
eg: If they knew how difficult it wasto drill through the hard rock, they would lose heart.

3.将来虚拟语气
eg: If peter should come agin, I would throw him out.

4.过去虚拟语气-过去完成时
eg: If , at the time , the British had not feared invasion, the tunnel would have heen sompleted.

条件状语从句转化为分词短语

分词短语表示条件,单从分词短语本身,是看不出来真实和虚拟的,只有从主句的时态才能看出来。
eg: Weather permitting, we'll go fishing.

虚拟语气的特殊用法

1.与客观真理相反的强烈虚拟语气,从句用were to + 动词原形,主句用过去将来时(would可改为should,might,could)
eg: If I were to live my life over again, I would have you as my wife.

2.主观意志动词‘建议’,‘要求’,‘命令’, 3大类之后的宾语从句,要使用助动词should(可省略)

3.should(ought to) have + 过去分词,表示与过去事实相反的推测,翻译为,本应该....
eg: He should have known that the police would never sllow this sort of thing.

4.wether引导的让住状语从句,可用虚拟语气。
eg: Whether it be bird, fish or beast, the porpoise is intrigued with anything that is alive.

5.wish后面的宾语从句,必须使用虚拟语气
eg: I wish he were here.

6.if only 用于虚拟,表示 ‘要是...该多好啊’(时态变化同wish)
eg: If only he were here.

结束语
