It is an iron door.这不是门,对吗不,这是门;是扇铁门;。

We all found _______ important to go to college.6._______ took us hours to do our homework.7._______ takes hardworking to go to college.9.it代替时间的六种固定模式:(1)it is time for sth=it is time to do sth“该到干…的时间了”(2)it’s time for sb for sth=it’s time for sb to do sth“该到某人干某事的时间了”(3)it’s time +that从句=it’s about time +that从句“该到干某事的时间了”注意:that从句用虚拟语气如同would rather+that从句用虚拟,它们的虚拟为时间段的虚拟—对现在/将来:一般过去时;对过去:过去完成时,此时的that从句一定用过去时(4)It is/was/will be +the+序数词+time+that从句“干…是第几次了”注意:A. it 可用this/that/yesterday代替B.序数词之后的time可用day/month/year代替C.that从句要根据主从句一致的原则使用现在完成时或过去完成时,也就是说,遇到be之后出现序数词+单数名词,它的从句:用that引导,且为完成时态(5)it+be+years/days/months+since+从句“自从…是多少年/天/月了”注意:A.主从句时态不一致B.be用is/has been代替,表现在完成时C.since后的从句要用一般过去时,体现since+过去时的句子为现在完成时的标志D.be有时也可用was代替,要注意时态的一致性,即since得从句由一般过去时变为过去完成时(6)it用于强调句型,强调除谓语动词之外的一切成分:It is/was +强调部分+that/who+原句其他成分,但一定要照抄不变,使用时注意:A. is/was体现主从句时态一致原则.B.强调部分若为人,既可用that也可用who,反之用thatC.当强调部分为名词,后又设两空,此时第一空根据定语从句的引导词判断,第二空根据强调句型的引导词判断D.强调句型变特殊疑问句,它的特殊疑问词就是所强调部分,结构:特殊疑问词+is/was it that+句中其他成分E.强调句若强调“直到…才”即not…until…句型时,此时一定要将主句中的not,从句中的until并列使用,构成强调句型,此用法类似于not…until…句型放于句首引起半倒装结构时,not…until…也要并列F.强调句型与it is/was +无介词的段时间和点时间的辨析(引导词):此时无介词的段时间引导词用before,表“…之后”,无介词的点时间用when,表“…时候”,反之有介词,引导词一律用that构成强调句注意:上述中点时间不一定指具体时间,可以为具体的一年/月/天G.强调句与其他句型不同的标志是:去掉it is/was以及that/who,句子仍成立E.g.1._______ is time that we _______ to work.A.
