关于虚拟语气要注意什么??
关于虚拟语气主要还有以下两种情况要注意。
1、没有条件从句的情形:除了以上所说的可以替代 if 的例子之外,还有如下两种可以替代if条件从句的情况。
(1)主语担任条件从句的功能时
Tom would have helped me on that occasion .
=If Tom had been there with me , he would help me .
在那种场合,汤姆将会帮助我。
(2)宾语担任条件从句的功能时
I could drink cocoa , not coffee .
=If you give me cocoa , not coffee , I could drink cocoa .
我可以喝可可,而不是咖啡。
说明:
上面两种情形,在同一句中也可以区别出,即是将重音置于表达条件从句的那个字上。
I would go with her .
是我的话,我会跟上她。
I would go with her .
是她的话,我将会跟着走。
2、条件从句省略的形式:此时不含虚拟的意思,只不过是作为参考条件而已。
I'll bring the book next time , if necessary .
=If it is necessary to bring the book .
假如必要的话,下次我会把书带来。
I'd like you to come tomorrow , if possible .
=If it is possible for you to come .
假如可能的话,我希望你明天能来。
补充:
句中若有表示数量的形容词(few / little)时,相对地表示要加以补足的话,用 if any(假如有的话)
They have little , if any , prejudice against Japanese people .
即使有的话,他们对日本人很少有偏见。
归纳:
(1)有表示经验的副词(seldom)时,使用 if ever .
They seldom , if ever , eat fish raw .
即使有的话,他们很少吃生鱼片。
(2)若表示一种不可能实现的愿望,常用 if only 来引导。
If only you would listen to reason .
你若听从道理就好了。
(3)otherwise / if not 含有对前面所说的事实加以否定的意思。
She blamed me , otherwise I would't have got amgry with her .
=If she had not blamed me I would't have got angry with her .
她责备我,否则我不会对她生气。
(假如她没有责备我的话,我就不会生气。)
(4)关系代词也可以用 if 来替代。
I am grateful to Mr.Smith , without whose help I might have been in trouble .
=I am grateful to Mr.Smith , if he had not helped me I might have been in trouble .
我对史密斯先生非常感激,假如没有他的帮助,我可能已经有麻烦了。
