名詞性從句的作用相當(dāng)于名詞，因此主語從句、表語從句、賓語從句和同位語從句分別作主句的主語、表語、賓語和同位語。同位語從句NounClauses(名詞性從句)SubjectClause(主語從句)AppositiveClause（同位語從句）ObjectClause（賓語從句）PredicativeClause（表語從句）Grammar3.Tofindyourwaycanbeaproblem.

eg:

Alovelydeskmateisneededbyme.WhoIneedislovely.主語從句定義：主語從句是在復(fù)合句中充當(dāng)主語的從句，通常放在主句謂語動詞之前或由形式主語it代替，而本身放在句子末尾。主語從句的引導(dǎo)詞：連詞that,whether

連接代詞

who(ever),whom(ever),which(ever),what(ever)連接副詞where,when,why,how1）從屬連詞：that，whether等.that

引導(dǎo)主語從句只起引導(dǎo)作用，本身無實(shí)際意義，在主語從句中不充當(dāng)任何成分，但不能省略。

注意:

由that引導(dǎo)的主語從句有時為了使句子結(jié)構(gòu)平衡,避免“頭重腳輕”,常用it

作形式主語,而把從句放在后面。例如:

1.That

hewillrefusethispieceofadviceisimpossible.______________________________________________________________________________2.Thattheyshouldlikeeachotherisnatural._____________________________________*it為形式主語Itisnaturalthattheyshouldlikeeachother.Itisimpossiblethathewillrefusethispieceofadvice.這樣就構(gòu)成了下面一些常用句型:

1)Itis+n.+從句

Itisapity/shamethat...遺憾的是……

Itisasurprisethat…令人驚奇的是…

Itisafactthat……是事實(shí)

Itiscommonknowledgethat……是常識*_______________(很遺憾)welostthematch.*______________(這是事實(shí))hecheatedintheexam.ItisapitythatItisafactthat2)Itis+adj.+從句

謂語形式為:should+V.原形

,should可省略。

eg.很奇怪，他竟沒有來。

Itisstrangethat___________________.

Itisimportantthatweshoulddoenoughsports.※heshouldnotcome②表示“據(jù)建議、據(jù)要求、據(jù)命令”It+be+suggested/advised/ordered/requested/commanded/insisted/requiredthat…謂語形式:should+V.原形

DelightthefansWhatdelightedthefans分析句子成分★如果成分齊全，那么考慮是否需要狀語。根據(jù)句子的意思確定是需要時間、地點(diǎn)、原因還是方式。（when,where,why,how）（2008年湖北卷第33題）______（我成長的）isveryhotanddampinsummer.（grow）我成長Igrowup我成長的地方…WhereIgrowupWhereIgrewup如果句子成分均已飽滿，意思也完整，那么考慮使用that。____the
