Step3Grammar
定義:用作主語的從句叫主語從句,它是名詞性從句之一。引導(dǎo)主語從句的連接詞有:連詞that,whether;連接代詞who,what和which;連接副詞when,where,how和why。
1)由what等代詞引起的主語從句:
Whattheteachersaidtodaywasquiteright.老師今天說的話是十分正確的。
2)由連詞that引起的主語從句:
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)情況下會放到整個句子的后部去,而用代詞it作形式主語。
3)由連接代詞或連接副詞以及whether引起的主語從句。
Whethertheywillsellthehouseisnotyetdecided.他們是否賣掉這所房子還沒有決定。
4)whatever,whoever也可引導(dǎo)主語從句。
Whateverwassaidheremustbekeptsecret.這里說的話都應(yīng)當(dāng)保密。
Whoevermakesmistakesmustcorrectthem.凡犯了錯誤的人都必須改正。
注意:上述例句中的主語從句都是放在句首,但有時為了使句子結(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:
Itisapitythatshehasmadesuchamistake.她犯了這樣一個錯誤,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+不及物動詞+從句
Itseems/appearsthat...似乎……
Ithappenedthat...碰巧……
3)It+be+過去分詞+從句
Itissaidthat...據(jù)說……
Itisknowntoallthat...眾所周知……
Itisreportedthat...據(jù)報道……
Itisbelievedthat...據(jù)信……;人們相信……
Itissuggestedthat...有人建議……
單個的主語從句作主語時謂語動詞用單數(shù);由and連接的兩個主語從句作主語時,謂語動詞用復(fù)數(shù)。

單項填空
—IwasdisappointedintimewhenIdidn’tpasstheexaminations.
—Don’tbesodiscouraged.You’llbesuccessfulin
time.(2009?12?河南平頂山檢測)
A./;/B.a;aC./;aD.a;/
解析:選D。句意為:——我沒通過考試那段時間我很失望?!獎e灰心。你遲早會成功的。第一個空考查的是when引導(dǎo)的定語從句,表示在某段時間里,故應(yīng)用inatime。而第二個空表示“遲早”,故用intime。
10.prevent...from
阻止;制止
Theheavyrainpreventedusfromgoingthere.
這場大雨使我們沒能到那里去。
易混辨析
prevent/stop/keep/protect
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”。
上述三個結(jié)構(gòu)中,在主動語態(tài)中stop與prevent后可省去from,但在被動語態(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后接能帶來傷害或損害的事物。
