one能够依照语义在它的前面或后面加上一些定语。

Ihaven’tapen,canyoulendmeone?

Ihopethereareenoughglassesforeachguesttohave______.A.itB.thoseC.themD.onetheone的用法:

theone,单数,特指,相当于“the+单数名词”,与所指代名词属同类,但不是同一个,具体哪个往往由其后面的定语决定。

Thereare35000nightclubsinTokyo,andyoudon’toftensee_____thatisempty.A.itB.thatC.oneD.theonethat的用法:

that,特指,单数,相当于“the+单数/不可数名词”,与所指代名词同类,但不同一,that能够依照语义在它的后面加上一些定语,多数是of短语;它的前面不能存在任何定语。

Myseatwasnextto_______oftheteacher.A.oneB.itC.thatD.seatNineintenparentssaidthereweresignificantdifferencesintheirapproachtoeducatingtheirchildrencomparedwith_______oftheirparents.A.thoseB.oneC.bothD.that形式主语形式宾语二、作引导词,在句中作或,代替后面的动词不定式、动名词或从句。

1)代替“todo”ItisimportantforustolearnEnglishwell.Ifounditnecessarytotellhimaboutthematter.2)代替“doing”Itisnousequarrellingwithhimaboutit.Ithinkitnogoodtalkingtoher.3)代替“clause”Itdoesn’tmatterwhetherhewillcomeornot.Ithinkitnecessarythatwewillattendthemeeting.

(一)it用作形式主语替代作主语的从句、动词不定式、动名词,而把真正作主语的从句、动词不定式、动名词置于句尾。

经常使用于以下特殊句式:

【一】经常使用的四种由it作形式主语的主语从句1.Itis/was+adj.+for/ofsb.todosth.that…2.Itis/was+过去分词+that…3.Itis/was+a/an+n.+that…

4.It+vi.(happenstosb./strikessb./takes+时刻/…)+that…1.Itis/was+adj.+for/ofsb.todosth.that…

(1)Itis/was+adj.+forsb.todosth.for前的形容词一样为描述事件的形容词:

如easy,difficult,necessary,impossible,important等______isillegal______amantodriveacarwithoutalicense.

(2)Itis/was+adj.+ofsb.todosth.of前的形容词一样为描述人的形容词:

如kind,clever,nice,rude,cruel,considerate,foolish,wise等It'skind______youtohelpmewiththeproblem.(3)it作形式主语,从句做真正主语①Itisclear(/obvious/true/possible/certain/…)that...很明显他已经明白了真相。

____________________________________________________________________②Itisimportant(/vital/essential/necessary/strange/natural/...)that...在此句型中,that后的从句中要用“should+动词原形”的形式,其中should能够省略,意为“竟然;应该”。

好勤学英语很重要。

____________________________________________________________________2.Itis/was+过去分词+that…①Itissaid(/reported/believed/thought/known/told/hoped/…)that...众所周知,姚明是世界闻名的足球运动员。

____________________________________________________________________②Itissuggested(/ordered/demanded/requested/commanded/…)that...在此句型中,that后的从句中要用“should+动词原形”的形式,其中should能够省略,意为“竟然;应该”。

大伙儿建议会议应该予以推延。

____________________________________________________________________

3.Itis/was+a/an+n.+that…Itisapity(/ashame/anhonor/fact/asurprise/...)that...该句型中,that后的从句一样用虚拟语气(should+动词原形)should可省去,表示出乎意料,常译为“竟然”。

没有这种意义时,那么不用虚拟语气。

例如:

Itisnowonderthat…难怪…你们班竟然发生如此的情形,真是件耻辱。

____________________________________________________________________他生病了,真遗憾!

____________________________________________________________________4.It+vi.(happenstosb./strikessb./takes+时刻/appears/seems…)+that…他似乎对打篮球不感爱好。

____________________________________________________________________令他震惊的是他竟然成功考上了大学。

____________________________________________________________________【二】It做形式主语,动名词做真正主语的常见句型有:

It’snogood(in)doing…做…没有益处It’snouse(in)doing…做…没有效记住:

Therebe的几个固定句型:

Thereisnopoint(in)doing…做…没成心义Thereisnosense(in)doing…做…没成心义Thereisnotrouble(in)doing…做…不困难Thereisnodifficulty(in)doing…做…不困难Thereisnopossibilitythat……是不可能的Thereisnodoubtthat…毫无疑问…There’ssomedoubtwhether/if…有疑问…【注意】:

加名词的一样为There,加形容词的一样为It,例外:

It’snouse/good(in)doingsth.【特殊情形】:

It’susefultodosth.It’suseless(/nouse)(in)doing…Thereisnoneed(forsb.)todosth.做…没有必要

(二)it作形式宾语当复合宾语中的宾语是不定式、动名词、宾语从句时,往往把宾语放在它的补足语后面,而用it作形式宾语,放在宾语补足语之前。

该句型中的it作形式宾语,经常使用的动词有think,believe,make,find,consider,feel等。

【6123结构】主语+动词+it+形容词/名词+不定式/动名词/从句6.指主句中经常使用的动词:

think,believe,make,find,consider,feel;1.指的是形式宾语it;

2.指的是宾补的两种形式:

形容词或名词;3.指的是真正宾语的三种形式:

不定式短语,动名词短语或that引导的宾语从句。

①常见的it做形式宾语组成的句型:

sb.think/find/consideritimportant(necessary/helpful…)(forsb.)todosth.that…我感觉天天早上高声读英语对我很有效。

____________________________________________________________________②makeitclearthat…弄清楚;使明白③takeitforgrantedthat…以为…是理所固然的④makeitarulethat…使…为适应⑤在动词like,love,enjoy,prefer,hate,appreciate后接if/when/that从句时一样用it做形式宾语。

结构为:

sb.like/love/enjoy/prefer/hate/appreciateitif/when/that…⑥在短语answerfor负责,dependon依托,insiston坚持,seeto负责,照顾后接从句时一样用it做形式宾语结构为:

dependon/insiston/seetoitthat…我以为在考试中作弊是不对的。

____________________________________________________________________若是她天天迟到的话我也无能为力。

____________________________________________________________________若是你给我些有效的信息,我将很感激。

____________________________________________________________________我讨厌人们边吃东西边说话。
