making

influentialon/uponbeinfluenced,whom语法it作形式主语一.概述：形式主语it并无实际语义，只是为满足语法上的需要，避免句子头重脚轻，它代替的是句子的逻辑主语。二.用法：it作形式主语，主要分为下列三种情况:不定式作主语、动名词作主语和主语从句作主语。具体分析如下:1.代指不定式，不定式真正主语后置；2.代指动名词，动名词真正主语后置；3.代指主语从句，主语从句真正主语后置。it作形式主语拓展延伸1.it代替从句：用作动词look,seem,appear,happen,occur,follow等的主语，例如：

◎Itlooksasifourschoolteamcouldwinthefootballmatch.

◎ItocurredtomethatIhadleftmypaperintheoffice.

◎Fromthiswitness,itfollowsthathemustacceptresponsibilityforthemistake2.固定句型如：

It'ssaid/believed/thoughtthat-clause3.习惯使用形式主语it代替动名词的句型：

It'swaste/nouse/good/useless+doingsth.跟踪训练1.Itisnouse_________(cry)overspiltmilk.2.Was________prettyhardforhimtobringupthechildonhisown.3.Itisconsiderednogood_________(recite)withoutunderstanding.4.Infact______isahardjobforthepolicetokeeporderinanimportantfootballmatch.5.Itseemsapity____________(waste)thefood.6._______apleasureitistoworkwithyou!7.Itiscommonknowledge______thefullmoonbringsfairweather.

单元重点句型

1.Nowonderitisn'tasurprisetosee....怪不得看到....并不意外。【句型分析】本句采用了省略形式，完整形式为：It'snowonderthat-clause.意为“不足为奇的是.....”;it作为形式主语，真正的主语从句后置。【句型拓展】a.It'sawonderthat-clause令人惊奇的是....b.Whatawonderitis(todosth)真是想不到！多令人惊奇！c.wonderwh-从句想知道，对...感到奇怪；d.wonderif/whether-clause不知道是否....

单元重点句型

2.Itisanindepedent,non-profitorganizationwhosemissionistoprovidemedicalcaretothoseaffectedbyconflict,epidemics,disastersoralackofaccesstohealthcare.

它是一个独立的非盈利性组织，其使命是向那些受冲突、流行病、灾害或缺乏保健服务影响的人提供医疗服务。【句型分析】划线部分为过去分词作后置定语，修饰those,相当于定语从句“thatareaffectedbyconflict,epidemics,disastersoralackofaccesstohealthcare.”【句型拓展】a.过去分词只表示状态，不表示被动情况，如fallenleaves;developedcountries;boiledwater;therisenrun;b.过去分词作定语，表示被动或者已经完成,如：deeplymovedfans;newly-builthouse;home-madefood,thebrokenbicycle;
