三、让步状语从句
句型19.
No matter what / which / who / where / when / whose+从句,+主句.(注意从句中的时态一般情况下用一般现在时态.)如:
No matter what you do, you must do it well.请比较:Whatever you do, you must do it well. 无论你做什么,一定要做好.
No matter where you go, please let me know.请比较:Wherever you go, please let me know.你无论去哪儿,请通知我.
(说明:这两种句型形式不同,而意义完全相同.)
(注意:I will tell whoever would like to read it. 句中的whoever不能用whomever来代替.因为它即作动词tell的宾语,又作后面从句的主语.)
四、条件状语从句
句型20.
When / So long as / As long as / Once +从句,+主句.(从句也可以放在主句之后.)如:
As long as you give me any money, I will let you go.只要你给我一些钱,我就让你走.
Once you have begun to learn English, you should learn it well. 一旦你开始学习英语,你应该把它学好.
句型21.
主句+on condition that+从句.如:
I will go with you on condition that you give me a sum of money.我和你一起去的条件是你给我一些钱.
句型22.
主句+unless+从句.(注意:由于unless本身是否定词,所引导的从句的谓语动词用肯定而不用否定.)如:
I will go there tomorrow unless it rains.我明天去那儿除非下雨.
句型23.
祈使句,+and/ and then+主句.(注意:祈使句也可用一个名词短语.)如:
Use your head, and you will find a good idea.动脑筋想一想,你就会想出一个好主意.
Another word, and I will beat you.你再说一句,我就揍你.
句型24.
If +necessary / impossible/ important等,+主句.(注意:if与形容词之间的it is被省略.)如:
If necessary, I will do it. 如果有必要的话,我来做此事.
