2025届高考英语一轮复习it+作形式宾语课件.pptx

It的用法

--It作形式宾语;Learningobjectives;;寒假作业还没写完......;;Theboythinksitdifficulttofinishhiswintervacationinonenight.;当不定式（短语）、动名词（短语）或从句在句子中作宾语时，为遵守英语中的尾重原则，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾。此时it只起引导作用，无意义（但不可省略）。

;二、it作形式主语的结构;Wethinkitnecessarytocleanourclassroomeveryday.

Hisparentsfoundituseless(nouse)arguingwithhim.

Ifeelitnoneedtalkingaboutitwiththem.

Hemakesitarulethathewillneverborrowmoney.

;1Iconsideritnouse___________(quarrel)withhimaboutit.

2Idon`tthink_______possibletomasteraforeignlanguagewithoutmuchmemorywork.

3.TheInternetmakesitpossible_________(share)thelatestnews.;2.形式宾语it后没有宾语补足语的情况;（2）某些动词加介词的短语中，如dependon,relyon,seeto,stickto,answerfor，insiston等，后面不能直接加宾语从句，而是先用it作形式宾语，再把真正的宾语从句放在后面。;(3)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.
