主语从句一、主语从句的含义在英语中,有的从句在复合句中的作用相当于名词,称作名词性从句。复合句中用作主语的从句叫主语从句。
二、主语从句的基本用法1.主语从句的引导词
(1)由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省略。That yu will win the medal seems unlikely.你获得奖牌看起来是不可能的。That yu are s indifferent bthers me.你如此冷淡使我很烦恼。(2)由连词 whether引导的主语从句:whether表示“是否”,在句中不做成分,不可以省略。Whether she is cming is still unknwn.她来不来还不知道。
(3)由连接代词wh,whse,whm,which,what,whever, whmever,whichever,whatever引导的主语从句:连接代词在句中起名词作用,充当一定成分。What yu need is mre practice.你所需要的是更多的训练。Whatever we d is t serve the peple.我们无论做什么都要为人民服务。
(4)由连接副词when,where,why,hw引导的主语从句:连接副词有含义,在句中做状语。When they will cme hasn't been made public.他们什么时候来还没有公之于众。
温馨提示　主语从句中连接词的选择技巧: 在确定主语从句中连接词的时候,可以根据连接词在从句中所做的语法成分和连接词在从句中的意义两方面进行考虑。
2.it做形式主语为了避免主语显得过长,尤其是陈述句做主语从句时,可以用it做句子的形式主语,把主语从句移到句子的末尾。
It's pssible that he has been t Beijing.他有可能去过北京。It's a fact that she has dne her best.她尽了最大努力,这是事实。It is reprted that a space statin will be built n the mn in years t cme.报道说未来几年里月球上将建造空间站。It seems that it is ging t rain.看起来好像要下雨。
温馨提示　(1)在“It + 系动词 + 形容词 + 主语从句.”句型中,如果形容词为necessary,imprtant,strange,natural等时,从句谓语动词常用“(shuld+)动词原形”。 It is imprtant that he (shuld) knw abut this. 他应该知道此事是重要的。
(2)在“It + 系动词 + 过去分词 + 主语从句.”句型中,如果过去分词为suggested,advised,rdered,requested,required等时,从句谓语动词使用“(shuld+)动词原形”。 It is suggested that the sprts meeting(shuld) be put ff. 有人建议推迟举行运动会。
三、主语从句中应注意的问题1.从句要用陈述语序Hw he succeeded finally is still a puzzle.他最后是如何成功的仍然是个谜。
2.主语为从句的主谓一致(1)主语为从句时,谓语动词一般要用单数形式,但如果what引导的从句做主语,代表复数概念(常可从表语上看出)时,谓语动词常用复数形式。What I need is yur help.我所需要的是你的帮助。What the schl needs mst are bks.这所学校最需要的是书。
(2)如果由and连接两个或两个以上的主语从句做主语时,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。
3.需要辨别以下几组引导词(1)whatever和wheverwhatever和whever可以引导主语从句,并在从句中做主语、宾语、表语等。此外,它们还可以引导让步状语从句,可以转换成n matter what/wh的形式。Whatever she did was right.她做的一切都是对的。(主语从句)Keep calm,whatever/n matter what happens.不管发生什么事都要保持镇静。(让步状语从句)
(2)what和thatwhat既有引导主语从句的作用,同时又在从句中做句子成分(主语、宾语、表语等)。这时what相当于all that/everything that...,常译成“……的(东西、事情、话等)”;而that只起连接作用,本身无实际意义,在从句中也不担当任何句子成分。但that引导的主语从句放在句首时,不能省略that。What we need is mre time.我们所需要的是更多的时间。That he is still alive is a wnder.他还活着,真是奇迹。
完成句子(1)很可惜你不能来参加我的生日聚会。　It's　 　a　 　pity　 that yu can't attend my birthday party. (2)有人建议这位老人到乡村休息一下。It's suggested that the ld man 　shuld　 　g　 　t　 　the　 　cuntryside　 t have a rest. 
(3)在我看来你好像不赞成这个计划。It seems t me 　that　 　yu　 　disagree　 　with　 　the　 　plan　. (4)我们在哪儿开会都无所谓。　Where　 　we　 　shall　 　have　 　the　 　meeting　 makes n difference. (5)他拒绝和你说话真是令人惊讶。　It　 　was　 　really　 　astnishing　 that he refused t talk t yu.
