It is/was表示地点的名词where+从句。(注意本句不是强调句型,而是以where引导的定语从句。)如: It was this house where I was born.请比较:It was in this house that I was born.(后一句是强调句型。) 句型10.

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。),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.
