牛津实用英语语法:340 让步从句

编辑:高中作文网

  它们由下列词来引导:although,though,even though,even if,no matter,however。有时也可以使用whatever。as也可以,但是只限于形容词+as+be结构。

  Although/Though/Even though/Even if you don’t 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 do,don’t touch this switch.

  无论怎样,都别碰这个按钮。

  However rich people are,they 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 drive,you 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 do,don’t 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 was,he 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 yourself,you 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 he’s your brother!

  —He may be my brother but I don’t trust him!

  —可他是你的兄弟!

  —尽管他是我的兄弟,可我不信任他!

  但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 won’t do anything about it.

  即便他发现了,他也不会采取什么行动的。
