.主語從句連接詞小結(jié)：that引導(dǎo)主語從句只起引導(dǎo)作用，本身無實際意義，在主語從句中不充當任何成分，但不能省略。Thatthegirllefthimbrokehisheart.1）從屬連詞：that，whether.Whethertherainwillstopisnoteasytosay.Whoevergetstheballwillmarryme.主語從句連接詞小結(jié)：2）連接代詞what、who、which、whosewhatever、whoever、whicheverWhateveryoudowillnottouchmyheart.Whoseideaitwascaughtourattention.主語從句連接詞小結(jié)：3)連接副詞when、where、how、why等。Whyhediditisnotreportedinthenewspaper.Whenwearrivedoesn’tmatter.Howhebecameagreatscientistisknowntousall.Tips：1.Whether可以引導(dǎo)主語從句，if不可；2.That引導(dǎo)主語從句時不做句子成分，但不能省略；誤：Theyshouldlikeeachotherisnatural.正：Thattheyshouldlikeeachotherisnatural.

Itisnaturalthattheyshouldlikeeachother.3.

主語從句的語序為陳述句語序；4.主語從句作主語時，謂語動詞的形式由主語所代表的內(nèi)容決定；Makesentences:

It’scertain.

Itdoesn’tmatter.It’scertainthatwewillbelate.Thatwe’llbelateiscertain.Wedon’tknowwhetherheiscomingornot.Whetherheiscomingisnotknown.Wedon’tknowwhathewantstotellus.Whathewantstotellusisnotknown.Whenyouwillcomebackdoesn’tmatter.Itdoesn’tmatterwhenyouwillcomeback.主語從句后置!

為了避免主語冗長,句子頭重腳輕,經(jīng)常用it作形式主語,主語從句放在后面作真正的主語.

例:Thatweshallbelateiscertain.--It’scertainthatweshallbelate.1.Thattheearthisroundisknowntoall.--2.Thatyoumissedthechanceisapity.--Itisapitythatyoumissedthechance.It’sknowntoallthattheearthisround.A.
