Subject Clauses
概念：復(fù)合句中用作主語的名詞性從句叫作主語從句。
1.連詞that在引導(dǎo)名詞性從句時本身沒有意義，在從句中不擔(dān)任任何句子成分，但引導(dǎo)主語從句時不能省略。
e.g. 1）That yu didn't knw the rules wn't be an excuse fr yur failure. 2）That the earth is rund is a fact. 3）As I searched the name Linda n the Internet，it became evident that there're tw with the same name wh lk cmpletely different.
考點總結(jié)1）that引導(dǎo)主語從句位于句首時，本身無意義，但是不可省略。2）that從句作主語時，常用it作形式主語，常見的句型有：
e.g. It is annunced in tday's newspaper that Xi Jinping will pay a visit t Russia next week
①It＋be＋形容詞(bvius，natural，surprising，etc.)＋that從句②It＋be＋名詞詞組(n wnder，an hnr，a pity，etc.)＋that從句③It＋ be＋過去分詞(said，reprted，thught，etc.)＋that從句
2.whether(注意不能用if)在主語從句中表示的意思為：是否。
e.g. 1）Whether she will win the prize is still unknwn. 2）Whether he will cme is nt decided. 3）It remains t be seen whether the newly frmed cmmittee's plicy can be put int practice.
3.連接代詞what（什么）, wh（誰）, which（哪一個）, —ever（無論）在從句作主、賓、表語等。
e.g. 1）Whever is the last t leave shuld turn ff the lights. 2）What sme scientists have fund is that their lng-term ues can smetimes harm bth the land and peple's health. 3）Whever wants t stay in a htel has t pay their wn way.
考點總結(jié)1．what引導(dǎo)名詞性從句時，意為“什么”或“……的”，在從句中用來作主語、賓語、表語或定語。2．wh－ever引導(dǎo)名詞性從句時，其作用等同于其前面的連接詞，意為“任何……”或“無論……”，含有強(qiáng)調(diào)的語氣。
e.g. 1）What wrries us mst is wh let ut the secret. 2）Whever breaks the law shuld be punished.
4.連接副詞when、hw、where、why，在主語從句中，表示的意思分別為：何時、怎樣、何地、為什么。
e.g. 1）Hw this culd be dne was a gd questin. 2）Why she didn't shw up remains a puzzle. 3）Where Li Bai，a great Chinese pet，was brn is knwn t the public，but sme wn't accept it.
5. It作形式主語為保持句子平衡，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：
e.g. 1）It’s pssible that he has been t England. 2）It’s a pity that yu didn’t take part in my birthday party. 3）It seems that it is ging t rain. 4）It is suggested that the dangerus marathn (shuld) be cancelled.
(1)在“It + 系動詞 + 形容詞 + 主語從句”句型中,如果形容詞為 necessary，imprtant , strange , natural等時,從句謂語動詞常用“(shuld)+動詞原形”。(2)在“It + 系動詞 + 過去分詞 + 主語從句”句型中,如果過去分詞為suggest , advise,request,require等時,從句謂語動詞使用“(shuld)+動詞原形”。
1．從句要用陳述語序Hw the accident happened was still a puzzle.
2．注意主謂一致(1)從句作主語時，主句的謂語一般用單數(shù)形式。Whether he will g hme r nt after graduatin has puzzled him much.
(2)如果由and連接兩個或兩個以上的主語從句作主語時，謂語動詞用復(fù)數(shù)； 由兩個或多個連接詞引導(dǎo)一個主語從句時，謂語動詞用單數(shù)。When and where they will hld the meeting is nt clear.When they will start and where they will g have nt been decided yet.
7.主語從句連接詞使用的判斷方法：Step1（從第二個動詞前）劃出主語從句Step2 找出從句的謂語動詞（觀察其前后是否少主賓等成分）Step3 連詞考慮順序： 連接代詞——連接副詞——whether——that
e.g. this culd be dne was a gd questin. this culd be dne was a gd questin. Hw this culd be dne was a gd questin.
