注意：

①

不管被强调部分是哪种状语，只能用that连接，不得使用where、when等连词.

．②被强调部分为人时，可用who(主格或宾格)和whom(宾格)代替that，用that也行。ItwasyesterdaythatImetyourfatherinthestreet．ItwasMikethat\who\whomIsawinthesupermarket．③强调句中也要注意主谓一致、人称一致和否定转移。④强调句型的特殊疑问句式为：

Itistheywhoareourfriends．

Itwasnotuntilteno'clockthatwegothomelastnight．Howisitthathe_______(go)toschooleveryday?Whowasitthat________(give)youanimpressivelesson?特殊疑问词+is\was+it+that?goesgaveWecalledonProfessorWangathisofficethismorning.weProfessorWangEg:Itwaswewho/thatcalledonProfessorWangathisofficethismorning.ItwasProfessorWangwhom/that/whowecalledonathisofficethismorning.WecalledonProfessorWangathisofficethismorning.athisoffice对thismorning进行提问的强调句ItwasathisofficethatwecalledonProfessorWangthismorning.WhenwasitthatwecalledonProfessorWangathisoffice?⑤注意不要混淆强调句和其他从句。Itiswas…that…为强调句标志，去掉后仍可组成一个完整的句子，只是没被强调,而其他从句一般不具备这一特征。

比较：

1)Itwasteno‘clockwhenwegothomelastnight．

2)Itwasatteno‘clockthatwegothomelastnight．

要点点拔第一句不是强调句，when不可改为that,因为去掉itwas和that后，只能组成“Wegothometeno'clocklastnight．”这样一个不完整的句子；第二句是强调句，that不可改为when．我们昨晚到家时已十点了。我们昨晚是在十点到家的。

A.It用作形式主语

当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。此时it只起先行引导作用，本身无词义。Itbe+adjnp.p(for/ofsb)todosth主语从句doingsth+B.It作形式宾语.(Formalobject)

Wethinkitourdutytocleanourclassroomeveryday.

HefeltitimportantlearningEnglishwell.

Theyfounditdifficultthattheywouldfinishtheirworkintwodays.Weconsideritimportanttolearnaforeignlanguage.

该句型中的it作形式宾语,为了记忆方便我们可称该句型为“6123结构”。

6指主句中常用的动词think,believe,make,find,consider,feel；1指的是形式宾语it；
