★主語從句為了避免頭重腳輕現象,用it做_______，而把從句放在后面充當_________。真正的主語形式主語為了避免主語冗長，句子頭重腳輕。經常用it作形式主語。例：Thattheearthisroundisknowntoall.=Itisknowntoallthattheearthisround.it作形式主語clear,obvious,likely,probable,true…句型一形容詞It+be+形容詞+主語從句

做是的Itispossiblethat...可能……Itis(un)likelythat...可能/不可能……Itisobviousthat…很明顯…Itisnecessary/essential/...that…很必要……Attention：

此句型中的形容詞是important,necessary等時，從句應該使用虛擬語氣。例：Itisimportantthatwe(should)learnEnglishwell.said,reported,believed,thought,announced…句型二過去分詞2.It+be+過去分詞+主語從句據Itissaid/told/heardthat...據說……Itiswellknowntoall...眾所周知……Itisreported/announced...據報道……Itisestimated...據估計……

Attention：

如果過去分詞是suggested,ordered,required,advised,requested等表示建議、要求、命令等詞時，從句應該使用虛擬語氣。例：Itissuggestedthatstudents(should)maketheirbedbythemselves.apity，anhonor，agoodidea，afact,a/nosurprise，nowonder(難怪)句型三名詞3.It+be+名詞+主語從句做是的Itisapity/shamethat...遺憾的是……Itisasurprisethat…令人驚奇的是…seem,happen,appear,look,occur,turnout(最后是;結果是)…句型四不及物動詞4.It+不及物動詞+主語從句Itappearsthat…
