如果一個從句在句子中擔當主語，那么這個從句就是主語從句。主語從句通常放在主句的謂語動詞之前，有時也由形式主語it代替，而本身放在句子末尾。ThatyouarecomingtoLondonisthebestnewsIhaveheardthislongtime.你將要來倫敦是這么長時間以來我聽到的最好的消息。Whethertheywouldsupportuswasstillaproblem.他們是否會支持我們還是一個問題。Whatimpressedmemostwasthattheyhaveallsufferedalot.讓我印象最深刻的是他們都受過很多苦。Isittruethatheisthegirl'sfather?他是那個女孩的父親，是真的嗎？1.Definitionofsubjectclause.2.ConjunctionsofNounClauses類別例詞說明從屬連詞兩者在從句中均不作成分，只起連接作用；that無實義，whether、if表示“是否”。連接代詞在從句中作主語、賓語、表語、定語等成分。連接副詞在從句中作時間、地點、方式、原因狀語等成分。that，whether，ifwho，what，which，whoever，whatever等when，where，how，why等Whatweneedismorewater.我們需要的是更多的水。Whetherwecanarrivethereontimedependsonthetraffic.我們是否能按時到達那里由交通情況而定。Whenthedelayedflightwilltakeoffdependsmuchontheweather.延遲的航班什么時候起飛主要取決于天氣狀況。當句子主語過長時，為保持句子平衡，避免頭重腳輕，常把主語從句后置，而用形式主語it代替。it作形式主語時常用于以下句型：句型說明It＋系動詞＋形容詞＋主語從句常用于此句型的形容詞有important，(un)likely，possible，necessary，natural，wrong等It＋系動詞＋名詞＋主語從句常用于此句型的名詞有afact，anidea，anhonour，awonder，nowonder，apity等It＋系動詞＋過去分詞＋主語從句常用于此句型的過去分詞有known，proved，said，decided，suggested，thought等It＋不及物動詞＋主語從句常用于此句型的動詞有appear，happen，seem，occur，matter等3.“it”usedasaformalsubject.Itisveryimportantthatastudent(should)learnEnglishwell.學生學好英語很重要。Itissuggestedthatthemeeting(should)beputoff.有人建議會議延期召開。Itdependsontheweatherwhethertheyaregoingshoppingtoday.他們今天是否去購物還得看天氣情況。Ithappenedthatshewasoutwhenhecalled.他打電話時，她恰巧不在家。Itisnowonderthatyourstudentshavemadesuchgreatprogress.難怪你的學生們進步這么大。(1)從句的語序在任何情況下，主語從句都用陳述語序,即主語在前，謂語在后。
