從句Itissaid(reported/believed.....)that...該句型中的it仍是形式主語,真正主語是that引導(dǎo)的主語從句;該結(jié)構(gòu)常譯為“據(jù)說(據(jù)報(bào)道,據(jù)悉…)”。ItissaidthathehascometoBeijing.HeissaidtohavecometoBeijing.②Itisv-edthat…

Itisapity(ashame/anhonor/agoodthing/afact/asurprise/...)that...該句型中,that后的從句一般用虛擬語氣(should+動(dòng)詞原形),should可省去。表示出乎意料,常譯為“竟然”。沒有這種意義時(shí),則不用虛擬語氣。如：Itisapitythatsuchathing(should)happeninyour

class.這種事竟然發(fā)生在你們班上,真是遺憾！Itisapitythatyoucan’tcome.

你不能來，真是遺憾！五、it作形式賓語

當(dāng)復(fù)合賓語中的賓語是不定式、動(dòng)名詞，賓語從句時(shí),往往把賓語放在它的補(bǔ)足語后面，而用it作形式賓語,放在賓語補(bǔ)足語之前。

該句型中的it作形式賓語,常用的動(dòng)詞有think,believe,make,find,consider,feel等。
