新希望英语语法精讲“It”作形式主语和形式宾语“It”作形式主语和形式宾语的用法详解It作形式主语和形式宾语用法，是英语学习的主要语法项目之一。无论是单项选择，还是完行填空，it用法始终是反复考查的重、热点之一。现将it在特殊句型中作形式主语和形式宾语用法，进行如下归纳分析，以供学习参考。一、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。.Itiswrongtotellalie.（说谎是错误的。）〔It为totellalie的形式主语〕Itisnousearguingaboutit.（争吵是没用的。）〔It为arguingaboutit的形式主语〕Itisuncertainwhowillcome.（谁要来还不确定。）〔It为whowillcome的形式主语〕It作形式主语的常见句型：①It+be+形容词+todosth./doing/that…..Itisveryimportanttolearnaforeignlanguage.（学一门外语非常重要。）Itisuselesscryingoverthespiltmilk.（覆水难收。）样的男士真让人惊讶。）②It+be+名词词组+doing/that…..Itisnogoodtellinglies.（撒谎没好处。）Itisapitythatyoudidn'tgotoseethefilmyesterday.（你昨天没看成那部电影真遗憾。）ItisatruththattherewouldbenonewChinawithouttheCommunistParty.（没有共产党就没有新中国，这是毋庸质疑的。）③It+be+过去分词+that….该句型常见动词有：say,hope,think,suppose,expect,report,know,believe,decide,etc..Itissaidthattheyhaveinventedanewtypeofcomputer.（据说他们发明了一种新型电脑。）ItisbelievedthatChinawillbecomeoneofthestrongestcountriesintheworld.（大家都相信中国将会步入世界强国之列。）Itwasreportedthatmorethan170thousandpeoplediedinthe2004tsunami.（据报道，至少有十七万人在2004年那场海啸中丧生。）④It+seems/appears/happens等不及物动词+that…..Itseemsthatheenjoyspopsongsverymuch.（似乎他非常喜欢流行歌①当不定式（短语）、动名词（短语）或从句在复合宾语结构中作某些动词的宾语时（如think,make,find,consider,feel,suppose等）；.TheyfounditpleasantthattheyworkedwithusChinese.（他们发现与我们中国人一起工作很愉快。）Idon'tfeelitdifficulttounderstandtheSpecialEnglish.（我觉得理解英语特别节目并不难。）Hemakesitarulenevertoborrowmoney.（他立志决不向别人借钱。）Ithinkitnoneedtalkingaboutitwiththem.（我认为没必要跟他们谈。）②某些表示“喜、怒、哀、乐”的动词，如like,enjoy,love,hate等，往往不能直接接宾语从句；.Idon'tlikeitthathe'ssolazy.（我不喜欢他那么懒惰。）Ihateitwhenmymotherasksmetoeateggs.（我讨厌母亲要我吃鸡蛋。）③that引导的宾语从句不能直接作介词的宾语；.Youmaydependonitthatweshallalwayshelpyou.（尽管放心，我们会随时帮你的。）Wouldyouseetoitthatshegetshomeearly（你负责保证她早到家，好吗？）Heinsistedonitthathewasinnocent.（他坚持说自己是无辜的。）④由及物动词与介词组成的固定搭配中，宾语从句若作该动词的宾语时，须借用it。.Ileaveittoyourownjudgementwhetheryoushoulddoit.（我让你自己判断这事是否该做。）Weoweittoyouthattherewasn'taseriousaccident.（多亏了你才没有发生严重事故。）?练习一?1.IsnecessarytocompletethedesignbeforeNationalDayA.thisB.thatC.itD.he2.Idon'tthinkpossibletomasteraforeignlanguagewithoutmuchmemorywork..A.thisB.thatC.itsD.it3.Doesmatterifhecan'tfinishthejobontimeA.thisB.thatC.heD.it4.Tom'smotherkepttellinghimthatheshouldworkharder,butdidn'thelp.A.heB.whichC.sheD.it5.isafactthatEnglishisbeingacceptedasaninternationallanguage.A.ThereB.ThisC.ThatD.It6.Ihatewhenpeopletalkwiththeirmouthsfull.A.itB.thatC.theseD.them7.Don'tthatallthosewhogetgoodgradesintheentranceexaminationwillprovetobethemostsuccessful.A.takeasgrantedB.takethisforgrantedC.tak...
