【正文】 語法專練：名詞性從句【考點(diǎn)透視】 在中學(xué)英語中，名詞性從句是復(fù)合句中構(gòu)成和分類最為復(fù)雜的部分。根據(jù)近年來高考英語命題的走向，今后它將仍然是考查的熱點(diǎn)。其主要考點(diǎn)分布在：名詞性從句的語序、名詞性從句的連接詞的辨析、有關(guān)名詞性從句的常見句型等。名詞性從句在句中的作用相當(dāng)于名詞，共有四種：主語從句、表語從句、賓語從句和同位語從句。引導(dǎo)名詞性從句的連詞有：①連接代詞：who，whose，whom，what，which。②連接副詞：when，where，why，how。③其他連接詞：that，whether，if，as if。 注意： ①連接代詞和連接副詞在句中不是疑問詞，因此從句中不用疑問式(即不要倒裝)。 ②連接代詞和連接副詞在句中充當(dāng)句子成分。③連接詞that，whether，if，as if在句中只起連接作用，不充當(dāng)句子成分。（一）主語從句 主語從句在句中作主語，它可以放在主句謂語動(dòng)詞之前，但是當(dāng)主語從句太長(zhǎng)時(shí)，可以把它放在句子后部，前面用it作形式主語，如：It doesn’t matter so much whether you will e or not. 你來還是不來，關(guān)系不大。(whether you will e or not是主語從句，it在句中作形式主語)（二）表語從句 表語從句在句中作表語，位于主句系動(dòng)詞之后。如： That’s why he was late. 注意：表語從句還可用as if引導(dǎo)。如： She looked as if she was going to cry.（三）賓語從句 賓語從句在句子中作及物動(dòng)詞或介詞賓語，在使用賓語從句時(shí)有以下幾點(diǎn)需要注意： 1．時(shí)態(tài)呼應(yīng)：當(dāng)主句謂語動(dòng)詞是過去時(shí)態(tài)，賓語從句要使用過去時(shí)態(tài)的某種形式。 2．介詞之后的賓語從句，一般不用if或which連接，要用what或whether。 3．whether和if都可以引導(dǎo)動(dòng)詞之后的賓語從句，二者?？苫Q，但是在正式文體中．或從句中有or not時(shí)，只用whether，不用if。4．注意否定前移：當(dāng)主句是I / We think (或suppose，expect，believe，imagine，guess) 時(shí)，其后的賓語從句如果是否定的，常常把否定詞not從從句移到主句。比較： I think you are not right. I don’t think you are right. I believe they won’t win the game.I don’t believe they will win the game.（四）同位語從句 同位語從句一般跟在某些表示抽象概念的名詞后面，用以說明名詞所表示的具體內(nèi)容。常跟同位語從句的名詞主要有：idea，news，fact，promise，answer，belief，condition．doubt，fear，hope，problem，proof，question，reply，report，suggestion，thought，truth等?！緦ｍ?xiàng)檢測(cè)】 1.
