2019屆高考英語名詞性從句專項復習
XX屆英語科5年高考3年模擬[浙江專版]
專題11 名詞性從句
【備考策略】
一、概念
在句子中起名詞作用的句子叫名詞性從句。名詞性從句的功能相當于名詞詞組,它在復合句中能擔任主語、賓語、表語、同位語、介詞賓語等, 因此可分別稱為主語從句、賓語從句、表語從句和同位語從句。主要考查語序問題、連接詞選用、時態的 呼應等
who will win the match is still unknown.
i want to know what he has told you.
the fact is that we have lost the game.
the news that we won the game is exciting.
2. 引導名詞性從句的連接詞可分為三類:
從屬連詞： that, whether, if 不充當從句的任何成分
連接代詞: what, whatever, who, whoever, whom, whose, which, whichever. （作主、賓、表、補）
連接副詞:
when, where, how, why, however, wherever（狀）
主語從句的用法
一、主語從句在復合句中作主語, 它可
以位于句首, 但常見的主語從句多放在
句末,句首則用形式主語it。
1.that the earth is round is true.
= it is true that the earth is round
2. whether he will come hasn’t been decided.
= it hasn’t been decided whether he will come.
注意: 連詞that, whether在從句中不擔任 句子成分,只起連接作用,不能省略 (注: if不可用來引導主語從句）
when he will go to america is not yet fixed.
(it is not yet fixed when he will go to america.)
whoever leaves the room last should close the door.
whatever we do must be in the interests of the people.
3.常見的it作形式主語的結構
1）it is a fact that he won the match.
2）it is necessary that we do study the english.
3）it is known to all that light travels in straight lines.
4）it seemed that he would come here
基本句型結構 常用詞語
it is + 名詞 + that從句 it is a fact/a shame/a pity/no wonder/
good news/…that…
it is + 形容詞 + that從句 it is necessary/strange/important/
possible/likely/…that…這類主語從
句中,謂語動詞常為(should)+動詞原形
it is + 過去分詞 + that從句 it is said/reported/decided/known/
…that…
it + 不及物動詞 + that從句 it seemed/happened/doesn’t
matter/has turned out/…that
二、it 作形式主語和it引導強調句的比較
it 作形式主語代替主語從句,主要是為了平衡句子結構, 主語從句的連接詞有變化。而it引導的強調句則是對句子某一部分進行強調,無論強調的是什么成分,都可用連詞that。被強調部分指人是也可用who/whom。例如:
it is a pity that you didn’t go to see the film.
it doesn’t interest me whether you succeed or not.
