340 让步从句

 

它们由下列词来引导:althoughthough(参见第327节与第329节),even thougheven ifno matterhowever(参见第85节)。有时也可以使用whateveras也可以,但是只限于形容词+asbe结构。

AlthoughThoughEven thoughEven if you dont like him you can still be polite

尽管/即使/纵然/即使你不喜欢他,你仍可有礼貌一些。

No matter what you dodont touch this switch

无论怎样,都别碰这个按钮。

However rich people arethey always seem anxious to make more mon ey

无论人们多么富有,他们似乎总还渴望赚到更多的钱。

However carefully you driveyou will probably have an accident eventual ly

无论你开车多小心,最后你大概还会出车祸。

Whatever you dodont tell him that I told you this

无论如何,别跟他说这件事是我告诉你的。

Patient as he washe had no intention of waiting for three hours

哪怕他再有耐心,也不打算等上三个小时。

may+动词原形可用于假设情况:

However frightened you may be yourselfyou must remain outwardly calm

无论你有多害怕,外表上你仍要保持冷静。

may含有I accept the fact that(我接受这一事实)的意思:

But hes your brother

He may be my brother but I dont trust him

―可他是你的兄弟!

―尽管他是我的兄弟,可我不信任他!

may这样用时,是另一主句的一部分,并不属于让步从句之列。should+动词原形结构可用于even if之后,正如用于条件句的if之后一样,用来表示should后面的动词原形所指的动作不太可能发生:

Even if he should find out he wont do anything about it

即便他发现了,他也不会采取什么行动的。
