Discvering Useful Structures：Subject Clauses
一、主语从句的基本用法1．主语从句的引导词【观察例句】在主语从句部分下面划横线That yu are cming t Lndn is the best news I have heard this lng time.你要来伦敦，这是这么长时间以来我听到的最好的消息。Whether it will d us harm remains t be seen.它是否对我们有害还要看一看。What I have seen tday has made a very deep impressin n me.今天我的所见所闻给我留下了非常深刻的印象。Whever breaks this law deserves a fine.触犯本法者应予以罚款。Whichever (f yu) cmes in first will receive a prize.(你们中)谁先进来谁得奖。
【练习1】——用whether, that, whever填空① ________ she became an artist may have been due t her father's influence.② ________ we will hld a party in the pen air tmrrw depends n the weather.③Every year, ________ makes the mst beautiful kite will win a prize in the Kite Festival.
主语从句中连接词的选择技巧(1)根据连接词在从句中所作的语法成分。(2)根据连接词在从句中的意义。
2．it作形式主语为保持句子平衡，常把主语从句后置，而用形式主语it代替。it作形式主语时常用于以下句型(见左表)【例句】It's pssible that he has been t Beijing.他有可能去过北京。It's a pity that yu didn't attend the meeting.你没参加这次会议太可惜了。It seems that it is ging t rain.看起来好像要下雨。It is imprtant that he shuld knw abut this.他应该知道此事是重要的。It is suggested that the meeting be put ff.有人建议会议延期召开。

It seems t me
It's a pity
It's suggested
【点津】(1)在 “It＋be＋过去分词＋主语从句” 结构中，过去分词若为 suggested /rdered /required /advised 等，主语从句中的谓语用(shuld) d。(2)在 “It＋be＋形容词＋主语从句” 结构中，若形容词imprtant/necessary/strange等，主语从句中的谓语用(shuld) d。
二、主语从句中应注意的问题1．从句要用陈述语序Hw he succeeded is still a puzzle. 他是如何成功的仍然是个谜。2．主谓一致(1) 从句作主语时，主句的谓语一般用单数形式。Where he will get a jb after graduatin has puzzled him much. 毕业后到哪儿找一份工作使他很困惑。(2) 如果由and连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句时，谓语动词用单数。When they will start and where they will g have nt been decided yet. 他们将在什么时候动身以及要去哪里还没定下来。When and where they will hld the meeting is nt clear. 他们何时何地召开会议还不清楚。
【点津】　what引导主语从句时，有时主句谓语动词应与主句中作表语的名词保持一致。What the schl needs mst are bks.这所学校最需要的是书。
