Step3Grammar
定義：用作主語(yǔ)的從句叫主語(yǔ)從句，它是名詞性從句之一。引導(dǎo)主語(yǔ)從句的連接詞有：連詞that,whether；連接代詞who,what和which；連接副詞when,where,how和why。
1)由what等代詞引起的主語(yǔ)從句：
Whattheteachersaidtodaywasquiteright.老師今天說(shuō)的話是十分正確的。
2)由連詞that引起的主語(yǔ)從句：
Thattheyarebadlyinneedofhelpisquiteclear.他們急需幫助，這是十分明顯的。
但是這類句子在大多數(shù)情況下會(huì)放到整個(gè)句子的后部去，而用代詞it作形式主語(yǔ)。
3)由連接代詞或連接副詞以及whether引起的主語(yǔ)從句。
Whethertheywillsellthehouseisnotyetdecided.他們是否賣掉這所房子還沒有決定。
4)whatever,whoever也可引導(dǎo)主語(yǔ)從句。
Whateverwassaidheremustbekeptsecret.這里說(shuō)的話都應(yīng)當(dāng)保密。
Whoevermakesmistakesmustcorrectthem.凡犯了錯(cuò)誤的人都必須改正。
注意:上述例句中的主語(yǔ)從句都是放在句首,但有時(shí)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(yǔ),而把從句放在后面。例如:
Itisapitythatshehasmadesuchamistake.她犯了這樣一個(gè)錯(cuò)誤,真是遺憾。
這樣就構(gòu)成了下面一些常用句型:
1)Itis+adj./n.+從句
Itisapity/shamethat...遺憾的是……
Itispossiblethat...很可能……
Itisunlikelythat...不可能……
2)It+不及物動(dòng)詞+從句
Itseems/appearsthat...似乎……
Ithappenedthat...碰巧……
3)It+be+過(guò)去分詞+從句
Itissaidthat...據(jù)說(shuō)……
Itisknowntoallthat...眾所周知……
Itisreportedthat...據(jù)報(bào)道……
Itisbelievedthat...據(jù)信……;人們相信……
Itissuggestedthat...有人建議……
單個(gè)的主語(yǔ)從句作主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞用單數(shù)；由and連接的兩個(gè)主語(yǔ)從句作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)。

prevent,stop,keep與protect四者的常見結(jié)構(gòu)為：
prevent...(from)doingsth.；stop...(from)doingsth.；keep...fromdoingsth.;均表示“阻止……做某事”。
上述三個(gè)結(jié)構(gòu)中，在主動(dòng)語(yǔ)態(tài)中stop與prevent后可省去from，但在被動(dòng)語(yǔ)態(tài)中不可省略;而keep...from...中的from在任何情況下都不能省略。另外，
protect...from...表示“保護(hù)……不受……侵襲；阻擋；防御”。from后接能帶來(lái)傷害或損害的事物。
Thisplanwillbekeptfrombeingcarriedout.
這個(gè)計(jì)劃將被阻止實(shí)施。
