——运用“形式—意义—使用”相结合的三维动态语法观
一、概念
名词性从句在句子中的作用相当于名词,主要有主语从句、宾语从句、表语从句和同位语从句。
名词性从句常用的引导词如下:
连词
that, whether, if
连接代词
what, which, who, whom, whose, whatever, whichever, whoever, whomever
连接副词
when,where,why,how,whenever,wherever, however
二、主语从句
主语从句就是在复合句中起主语作用的从句。
1.that,whether引导的主语从句
【先感悟】
①That the earth moves around the sun is known to all.
②It is obvious to the students that they should get well prepared for their future.
③It is reported that more than 500 runners will participate in the marathon.
④Whether life on other planets does exist is yet to be proved, but the signs are promising.
⑤It is uncertain whether/if he will attend the meeting on time.

(2)句②③中的It作 ,把that引导的主语从句后置;
(3)句④⑤中的 引导主语从句,在从句中不作任何成分。
【善归纳】
(1)that引导主语从句时,在从句中不作任何成分,也没有意义,但不可省略。
(2)that引导主语从句时可用it作形式主语,把that引导的主语从句后置,that不可省略。常见句式主要有以下几种:
①It+be+形容词(necessary、important、certain、clear等)+that从句;
②It+be+名词短语(a pity、a shame、a fact、an honour等)+that从句;
③It+be+过去分词(said、told、heard、reported等)+that从句;
④It+特殊动词或短语(seem、appear、turn out、occur to等)+that从句。
(3)whether引导主语从句时,在从句中不作任何成分,但有具体的含义,意为“是否”。
主语从句位于主句谓语动词前,表示“是否”,只能用whether。若用it作形式主语,则whether与if可互换。
