句型17.
由which引导的非限定性的定语从句。如:
He is a professor, which I have been looking forward to becoming. 他是个教授,那是我一直盼望的职业。(因为先行词professor是表示职业的名词,因此引导词用which,而不用who。)
句型18.
由where, when引导的定语从句(其中包括限定性的或非限定性的。)如:
This is the house where I used to come.
请比较:This is the house which / that I used tocome to.
This is the day when I joined the Party.
请比较:This is the day which / that I joined the Party on. (说明:关于that与which之间的区别,请看关系代词that和which的区别。)
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。)
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。 |
