中考英語語法：it作形式主語和形式賓語的用法

中考英語語法：it作形式主語和形式賓語的用法一it作形式賓語1）當(dāng)不定式短語、動名詞短語或從句在復(fù)合賓語（賓語+賓補）結(jié)構(gòu)中作某些動詞（find,make,think,consider,feel,suppose等）的賓語時。如：Theyfoundit

pleasantthattheyworkedwithusChinese.他們發(fā)現(xiàn)與我們中國人一起工作很愉快。(pleasant是賓語補足語，thattheyworkedwithusChinese是賓語從句）Idon’tfeelit

difficulttounderstand

theSpecialEnglish.我覺得《特別英語》節(jié)目并不難理解。（difficult是賓補，tounderstand

theSpecialEnglish是真正賓語）Hemakesit

arulenevertoborrowmoney.他立志決不向別人借錢。（arule是賓補，nevertoborrowmoney是真正賓語）Ithinkit

noneedtalkingaboutitwiththem.我認(rèn)為沒必要跟他們談這事。（noneed是賓補，talkingaboutitwiththem是真正賓語）2）某些“喜、怒、哀、樂”的動詞，如like,enjoy,love,hate等，往往不能直接接賓語從句，需要用it作形式賓語。Idon’tlikeit

thathe’ssolazy.我不喜歡他那么懶惰。（thathe’ssolazy是真正賓語）Ihateit

whenmymotherasksmetoeateggs.我討厭母親要我吃雞蛋。（whenmymotherasksmetoeateggs是真正賓語）1）that引導(dǎo)的賓語從句不能直接作介詞的賓語。如Youmaydependonitthatweshallalwayshelpyou.盡管放心，我們會隨時幫你的。Heinsistedonit

thathewasinnocent.他堅持說自己是無辜的。（thathewasinnocent是真正賓語)Wouldyouseetoitthatshegetshomeearly？你負(fù)責(zé)保證她早到家，好嗎？3)由及物動詞與介詞組成的固定搭配中，賓語從句若作該動詞的賓語時，須借用it.Ileaveittoyourownjudgement

whetheryoushoulddoit.我讓你自己判斷這事是否該做。（whetheryoushoulddoit是真實賓語）Weoweittoyou

thattherewasn’taseriousaccident.多虧了你才沒發(fā)生嚴(yán)重事故。（

thattherewasn’taseriousaccident.是真實賓語）二it作形式主語it作形式主語當(dāng)主語是動詞不定式（短語）、動名詞（短語）或從句時，為保持句子結(jié)構(gòu)前后平衡，避免頭重腳輕，常用it作形式主語。而將真正的主語放在句尾。此時只起引導(dǎo)作用，本身無意義。Itiswrongtotellalie.說謊是錯誤的。(totellalie是真實主語）Itisnouse

arguingaboutit.爭論這件事是沒用的。(It為arguingaboutit的形式主語）Itisuncertainwhowillcome.誰要來還未確定。(it為whowillcome的形式主語）三it作形式主語的常見句型１）It＋be＋形容詞＋todosth/doing/that...Itisveryimportant
