it的用法和练习进步带规范标准答案
重点代词it的用法和练习(含答案)
(1)it用做人称代词的用法it用作代词,意为“它”,既可以指人,也可以指物。
it做人称代词,可以用来代替一个名词、短语、从句或句子,以避免他们在句中的重复。
这是可以指提到过的,也可以指未提到的,在句中做主语、表语和宾语。
1)指事物,it可以知道除人以外的任何事物或动物。
Idroppedmywatchanditbroke.我把手表掉在地上摔坏了。
2)指人,it主用用于指性别不明的婴儿或只听其声不见其人的人,如:
Isitaboyoragirl?
是男孩还是女孩?
Thereisaknockonthedoor.Itmustbethepostman.“Listen.Someoneiscrying..”“Oh,itmustbeMary.”3)代替某些代词。
代词it可以用于代替指示代词this,that以及复合不定代词something,anything,nothing等,如:
“What’sthis?
”“It’sanewmachine”
(2)it用作非人称代词的用法1)it用作非人称代词主要用来指时间、距离、价值、天气、气温及温度等自然现象。
如It’stoolatetogotherenow.现在去那已经太迟了。
Itrainedalldayyesterday.昨天下了一整天雨。
2)用于某些句型。
It’stimeforsth.该做某事了。
It’stodosth.是时候该做某事了。
It’stimeforsbtodosth.某人该干某事了。
It’s(about/high)time+that--从句。
某人该做某事了。
(从句谓语用过去式,有时候用should+动词原形)It’sfirst(second)time+that--从句。
某人第几次干某事。
(从句谓语动词用现在完成时)It’s+时间段+since从句。
自从„以来有一段时间了。
It’s+时间段+before从句。
过多长时间才„(3)it用作形式主语的用法。
1)当不定式、动名词、从句等复杂成分做句子主语时,为保持句子的平衡,通常把真正的主语放在句末,而句首使用形式主语it。
如It’sveryimportanttorememberthis.It’shardworkclimbingmountains.It’sunknownwhenhewillcome.
2)it用作形式主语的重要句型。
①It+be+adj.+for(of)sbtodosth.某人做某事„Itishardforhimtomakeuphismind.他很难下定决心。
Itwasfoolishofhertosaysuchathing.她说那样的话,太愚蠢了。
提示:
此句型中的介词of和for的区别是:
of用于指某人的性格,属性,特征等。
介词for表示对象,意为“对„来说”。
②Ittakes/tooksb+时间段+todosth.某人做某事花了„时间。
Ittookmetwohourstofinishmyhomework.③Itisuptosbtodosth.该由某人做某事了。
It’suptoyoutomakethechoice.该由你来做选择了。
④Itlooks(seems,appears,happens,occurs)that(asif)„似乎„Itseemsasthoughhedidn’trecognizeme.(4)it用作形式宾语的用法。
1)当不定式、动名词、从句等复杂成分用作宾语且后面跟有宾语补足语时,通常会在宾语补足语前使用it作形式宾语,而将真正的宾语移至句末。
其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”Ifinditdifficulttodothejobwell.Ithinkitbestthatyoushouldstayhere.Wethinkitnousecomplaining.2)用作形式宾语的几个特殊结构:
①动词+it+that-从句Ithinkit(that)hewillcomeontime.②动词+it+when(if)-从句Werallyappreciateitwhensheofferedtohelp.③动词+prep.+it+that-从句Ican’tanswerforitthathewillcome.我不能保证他会来。
④动词+it+介词短语+that-从句Itookitforgrantedthathewouldhelpus.(5)it在强调句中的用法。
