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

He is good at English, and ________ is known to us.8.it作形式主语的九种固定模式：（1）it+be+adj+to do, to do为句子的主语，但为了避免头重脚轻，用形式主语it 代替，译为汉语时，用to do代替it，it不译（2）it+be+adj+that从句，that从句为主语，用it代替注意：当that从句在adj后时，that可不写；放在一句话的句首起强调作用时，that引导名词性从句虽属二无（不作主语，不作宾语）形式，但不可省略（3）it+be+n+to do, 常用名词（n）:pity, honor, shame, duty, wonder（4）it+be+n+that从句，it用法同上，名词用法同上（5）it+be+no good/no use/useless+doing“干…没有好处（用处）”注意：it后的名词若变为no doubt，be之前的主语不能用it，用there （6）be said“据说”、be reported“据报道”、be announced“据宣布”、be known “据了解”、be believed“据推测”、be hoped“据希望”等结构后+that从句，句子的主语用it代替that从句作形式主语（7）seem/appear+that从句，句子的主语用it，用法同上注意：在（6）（7）两种结构中that从句可换成to do的三种形式（to do, to be doing, to have done）此时要特别注意，此时it不再充当主语，主语由that从句中的主语充当（8）it在make, think, consider, find, feel后可作形式主语或宾语，条件为：在it 后有宾语补足语、形容词或形容词修饰名词出现，而在形容词或形容词修饰的名词后又有to do或that从句出现来做以上动词之后真正的主语或宾语，但为了避免头重脚轻用形式主语或宾语it（9）用于it takes sb some time/some money to do sth中代替to do 作主语，表“花费某人多少时间/金钱干某事”，此句型中的sb可省，take译为“需要”，相当于needE.g.1._______ is important for us to learn English well.2._______ is clear that he is the best in his class.3._______ is no good _______ (take) in your parents.4._______ is no doubt that he has gone to college.5. 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. It, goB. It, wentC. That, goD. That, went2._______ is the third time that she _______ you.A. It, ringsB. It, has rungC. It, had rungD. That, had rung3.
