单元语法主语从句在句中起主语作用的从句叫主语从句,它是名词性从句之一。引导主语从句的连接词:从属连词:在从句中不作成分连接代词:在从句中作主语、宾语、表语或定语连接副词:在从句中作状语
1 引导主语从句的连接词(1)从属连词:that,whether,if① that 在从句中不充当句子成分,也没有实际意义,只起连接作用,但不可省略。That smking is harmful t health is knwn t everyne. 吸烟有害健康,这是大家都知道的。② whether 在从句中不充当句子成分,只起连接作用,意为“是否”。whether 引导的主语从句既可放在句首,也可放在句末。而 if 引导的主语从句不能放在句首,只能放在句末。Whether life exists n ther planets is nt clear yet. 其他星球上是否存在生命还不清楚。It is still dubtful whether/if she will play the rle. 她是否要演这个角色还很难说。
( 2)连接代词:wh,whm,whse,what,which,whever,whatever,whichever 等连接代词在从句中作主语、宾语、表语或定语,起连接作用并且有实际意义。Wh will bring up the child hasn’t been decided yet. 谁来抚养这个孩子尚未决定。Which lifestyle is the mst beneficial t ur health is still unknwn.还不知道哪种生活方式对我们的健康最有利。Whever slves the puzzle can receive the award. 无论谁解开这个谜团都可以得到奖赏。Whatever yu d shuld d n harm t thers. 无论你做什么都不应该伤害别人。(3)连接副词:when,where,why,hw when,where,why,hw 在从句中作状语,分别表示时间、地点、原因和方式,起连接作用并且有实际意义。When we will set ff hasn’t been decided. 我们何时出发还没有决定。Why he spied n me puzzled me fr a lng time. 他为什么监视我这个问题困扰了我很长时间。Hw he earned his living befre is nt clear t us. 我们不清楚他以前是如何谋生的。

2 用 it 作形式主语的主语从句当主语从句太长时,为了平衡句子结构,常用it作形式主语,而把主语从句后置。用it作形式主语的常见句型有:(1)It+be+ 形容词 +that 从句.常用于该句型的形容词有clear,bvius,true,natural,pssible,likely,certain,frtunate,strange,necessary,imprtant 等。It is clear that the girl tld a lie. 很明显,那个女孩说谎了。It’s pssible that Mira might turn up tnight. 米拉今晚可能会来。(2)It+be+ 名词(词组)+that 从句.常用于该句型的名词(词组)有 a pity,a shame,gd news,a fact,an hnur,a wnder,n wnder 等。It is a pity that yur parents didn’t permit yu t g with us. 你父母不允许你和我们一起去,真遗憾。It’s a wnder that n ne gt hurt. 竟然没有人受伤,真是奇迹。

(4)It + 不及物动词(短语)+ that 从句.常用于该句型的不及物动词(短语)有seem(看上去),turn ut(结果是),happen(碰巧),appear(显得)等。It turned ut that we were wrng. 结果是我们错了。It happened that he was ut that day. 碰巧他那天不在家。(5)其他句型It desn’t matter whether he likes it r nt. 他喜不喜欢它都没有关系。It makes n difference whether yu supprt my plan r nt. 你支不支持我的计划都不重要。It suddenly ccurred t me that I had left my purse at hme. 我突然想起我把钱包落在家里了。
同义句转换(每空一词)(1)That he suddenly fell ill last mnth surprised us.= _________ _________ _________ _________ he suddenly fell ill last mnth.(2)Whether they will sell the huse hasn’t been decided yet.= _________ _________ _________ _________ _________ _________ they will sell the huse.(3)That light travels in straight lines is knwn t us all.=_________ _________ _________ _________ _________ _________ _________ light travels in straight lines.

3 使用主语从句时的注意事项(1)主语从句应用陈述语序Whether he will be in time fr the meeting is dubtful. 他能否赶上会议还很难说。(2)主谓一致问题① 单个从句作主语时,谓语动词一般用单数。但what引导的主语从句作主语时,谓语动词的数应与作表语的名词一致。When we shall have ur sprts meeting has nt been decided yet. 我们何时开运动会还没定下来。What astrnauts need in the spaceship is xygen. 宇航员在宇宙飞船中需要的是氧气。What the children in the area starve fr are bks. 这个地区的孩子们渴望得到的是书。② 用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;用两个或两个以上连接词引导一个主语从句时,谓语动词用单数。When they will set ff and where they will g have nt been decided yet. 他们何时动身,要去哪里,都还没定下来。When and where the meeting will be held has nt been decided yet. 会议将在何时何地举行还没定下来。
③ whether引导的主语从句,如果用了形式主语it,引导词whether可以换成if。如果whether从句位于句首或后面跟 r nt 时,不能换成 if。It has nt been decided yet whether/if he will cut dwn his nvel.=Whether he will cut dwn his nvel has nt been decided yet.他是否会删减自己的小说还没决定。I dn’t knw whether r nt my sn can earn his living. 我不知道我儿子是否能自力更生。【用法比较】whether 与if 引导名词性从句
单句语法填空(1)What surprised me mst __________(be)that the man in rags was a millinaire.(2)What he needs mst __________(be)mney.(3)When and where the new hspital will be built __________ (remain) a mystery.(4)That the cal wrkers are still alive __________(be) a wnder.(5)Whever tld yu that __________(be)lying.(6)Whichever climber gets t the tp first __________(get)a £5,000 prize.(7)What the famus singer ffered her fans __________ (be) lve and kindness.(8)What he chiefly wished fr __________(be)a chance t explain.
