最新整理高中英语虚拟语气知识点分析.docx
最新整理高中英语虚拟语气知识点分析虚拟语气,就是一种假设,假设的是与事实(过去、现在或将来)相反的情况。
一、什么是虚拟语气虚拟语气表达的是与事实相反或没办法实现的情况,表示说话人的遗憾、后悔、愿望、建议、命令和要求等情绪。
下面我们通过几个例句来进一步了解虚拟语气:1.如果我住在办公室附近,我就会步行上班。
判断是否译为虚拟语气,主要看句子中的条件能否实现,如果不可能实现(即与事实相反的情况),就为虚拟语气。
我们来进行分析:真实条件(能够实现):我自己的房子离上班地很远,所以又在办公室附近租了间房。
在这种情况下,“如果我住在办公室附近那间租的房里”为能够实现的条件,所以译为陈述语气。
IfIlivenearmyoffice,Iwillwalktowork.(主将从现)虚拟条件(不能实现):我自己的房子离上班地很远,天天坐地铁上班。
这时,“如果我住在办公室附近”是与事实相反的情况,译为虚拟语气。
IfIlivednearmyoffice,Iwouldwalktowork.这里用lived和would偏离了正确的语法运用,都使用了过去式形式,大家可以理解为,虚拟语气就是用错误的语法表达不可能实现的条件。
这里表达的是和现在事实相反的情况。
2.如果我在你的位置,我就会让他知道我对他的看法。
(1)IfIwereinyourshoes,IwouldlethimknowwhatIthoughtofhim.(2)WereIinyourshoes,IwouldlethimknowwhatIthoughtofhim.“我在你的位置上”与事实相反,所以译为虚拟语气。
虚拟语气中无论主语是什么形式,be动词一律用were。
我们还需注意的是,虚拟语气句式可以省略if,将谓语动词were提前,以进行强调。
这里表达的是和现在事实相反的情况。
3.如果这些玩具运到时有损坏,你可以立刻通知我们。
(1)Ifthetoysshouldarriveinadamagedcondition,youcouldinformusatonce.(2)Shouldthetoysarriveinadamagedcondition,youcouldinformusatonce.正常语法情况下,划线单词应该用“will”和“can”,但这里为虚拟语气,所以使用“should”和“could”这些不太正常的语法。
高考英语语法精品讲练:第三章虚拟语气
高中英语语法精讲第三章虚拟语气虚拟语气(the subjunctive mood),又称假设语气,是谓语动词的一种形式,表示说话人叙述的内容与事实相反,在现实中并不存在,或实现的可能性很小。
一、动词的语气语气用来区别讲话人对某一行为或事情的看法和态度。
英语中的语气(mood)有三种,分别是陈述语气、祈使语气和虚拟语气。
1.陈述语气陈述语气一般用来叙述事实或就事实提出询问,主要用于陈述句、疑问句和某些感叹句。
Where there is a will, there's a way.有志者事竟成。
Can you help me carry the box upstairs你能帮我把箱子搬到楼上吗?How I missed the life in the countryside! 我多么想念乡村的生活啊!2.祈使语气祈使语气表示说话人向对方提出请求或下达命令。
Come this way, please! 请这边走。
Don't make any noise, will you别吵,行吗?Do be careful when crossing the street.过马路时一定要小心。
3.虚拟语气虚拟语气表示动作或状态不是客观存在的事实,而是说话人的主观愿望、假设或推测等。
If I were a bird, I could fly in the air.如果我是一只小鸟,我就能在空中飞行。
I wish it were spring all the year round.但愿四季如春。
May good luck be yours! 祝你好运!二、条件句中的虚拟语气英语中条件从句有两类,一类是真实条件句,另一类是非真实条件句。
如果假设的情况可能发生,是真实条件句;如果假设的情况是不存在的或不大可能发生的,则是虚拟条件句。
A.真实条件句真实条件句表示的假设是可能发生或实现的,主句和从句的谓语动词都要用陈述语气。
