【要义详析】一、主语从句(subject clause)1. 在复合句中充当主语的从句称之为主语从句, 一般置于句首。主语从句引导词有: (1)连词that和whether, 在主语从句中只起连接作用, 不充当任何成分。(2)连接代词wh, whever, whm, whse, what, whatever, which, whichever, 在主语从句中充当主语、宾语、表语。(3)连接副词when, where, hw, why, 在主语从句中作状语。*That he wrked ut the cmplex prblem astnished ther students. 他解决了这个复杂的题目让其他同学感到惊讶。
*When the exam f qualificatin will be held hasn’t been decided. 资格考试什么时候举行还没决定。*Whether he will participate in this campus art festival isn’t clear.  他是否参加这次校园艺术节还不清楚。*What wrried the ld cuple was that their children gt invlved in the crime.  令这对老夫妇担忧的是他们的孩子参与了这次犯罪。*Whatever happens yu may be quite sure that I will nt blame yu. 不管发生什么事, 你可以确信我不会责备你。
2. 为了防止句子头重脚轻, 通常把形式主语it放在句首位置, 真正主语置于句末。it作形式主语的常见句型有: (1)It is a (fact, pity, questin, wnder, gd thing, surprise ) that. . . (2)It is necessary (imprtant, strange, natural, etc. ) that sb. shuld d表达惊奇、不相信、惋惜、理应如此等语气。(3)It is said (expected, believed, thught, hped, knwn, reprted, estimated, required. . . )that. . . (4)It seems(happened/appears/desn’t matter /makes n difference /ccurred. . . )that. . .
*It is well knwn t all f us that the trees can’t grw withut sunlight and water. 众所周知, 树木生长离不开阳光和水。*It is said that the new adaptatin will cme ut next year . 据说这个新改编本将在明年出版。*It has yet been decided when the tutr will cme t give us a speech.  这个导师什么时候来给我们做演讲还没定下来。
【名师点津】that引导主语从句的省略原则　　连词that 的省略原则: 若that引导的主语从句直接位于句首, 则that不能省略; 若使用了形式主语it, 则that有时可以省略。例如: That yu didn’t g t the talk was a pity. 很遗憾你没去听报告。(that不可省)It was a pity (that) yu didn’t g t the talk. 很遗憾你没去听报告。(that可省)
【即学活用】(1)语法填空①_____she has became an artist may have been due t her father’s influence. ②________he can get a nursing qualificatin remains t be seen. ③_____will happen in the wrld is difficult t predict. ④_____will take the place f ur riginal headmaster hasn’t been decided yet. (2) __________________________next week is being discussed.  我们下周在哪里野餐正在讨论中。
Where we will have the picnic
(3) ______________the chance f studying abrad is unknwn.  他为什么放弃出国留学的机会不得而知。(4) _________________is nt clear t anyne.  这事怎样发生的, 谁也不清楚。
Why he gave up
Hw this happened
二、宾语从句(bject clause)1. 定义: 在主从复合句中充当宾语的从句叫宾语从句。它可以作谓语动词的宾语, 也可以作非谓语动词、某些介词或形容词等的宾语。*It is flish t believe that ne’s race and civilizatin are superir t thers. 认为自己的人种和文明高人一等是愚蠢的。*(2020·天津高考)But nce having met and liked them, we think hw terrible it wuld have been, had we missed the chance. 但一旦我们认识并喜欢上了他们, 我们就会想, 如果我们错过了这个机会, 那将是多么可怕的事情。
*(2018·全国卷Ⅲ)I’m nt sure wh is mre frightened, me r the female grilla that suddenly appears ut f nwhere. 我不知道我和不知从哪里突然冒出来的雌性大猩猩谁更害怕。*I dn’t knw whether he can win back the belief f the teacher. 我不知道他是否能赢回老师的信任。
2. 由连接词that引导宾语从句时, that在句中不充当任何成分, 在口语或非正式的文体中常被省去。(2021· 浙江高考)In a study f 33 years f trends in Bdy Mass Index acrss 200 cuntries, the scientists fund that peple wrldwide are getting heavier and that mst f the rise is due t gains in BMI in rural areas. 在一项对200个国家33年体重指数趋势的研究中, 科学家们发现, 世界各地的人们都在变得越来越重, 而这主要是由于农村地区体重指数的增加。
【名师点津】宾语从句中两种情况中的连接词that不能省略: ①引导的第二个宾语从句前的that不可省; ②在动词+形式宾语it+宾语补足语+that引导的宾语从句中that不能省略*I believe (that) yu will keep yur wrd and that yu will turn up at the party n time. (第二个that不能省)我相信你会遵守诺言, 准时出现在晚会上。
3. whether/if引导的宾语从句。whether/if在从句中不充当成分, 但是有“是否”之意, 从句要用陈述语序。【名师点津】 只用whether不用if引导宾语从句　　在宾语从句中, 引导词whether和if基本一样, 但下面两种情况只能使用whether: ①引导介词后的宾语从句时; ②和r nt一起连用时。
【即学活用】(1)I truly believe ____beauty cmes frm within. (2)The ld wman asked me __________I knew the way t the hspital.  (3)Jhn said ____he was leaving fr Lndn n Wednesday. (4)(2019·北京高考)Yu will questin _______the vice yu’re hearing is actuallyreal.
if /whether
4. 连接代词及连接副词引导的宾语从句。连接代词及连接副词引导的宾语从句相当于特殊疑问句, 连接词都在从句中充当一定的成分。*Is there anything wrng in what I said? 我所说的有错误之处吗? *We prmise whever attends the party a chance t have a pht taken with the mvie star. 我们许诺, 任何参加这个聚会的人都有跟那个电影明星合影的机会。*It was a lng rad t get where Yan Ning is nw. 颜宁花了很长时间, 才有了今天的成就。
【即学活用】(1)Jane mved aimlessly dwn the tree-lined street, nt knwing ______she washeading. (2)If yu swim in a river r lake, be sure t investigate _____is belw the water surface. (3)The exhibitin tells us ____we shuld d smething t stp air pllutin.
5. 在insist, demand, rder, suggest, prpse, advise等表示坚持、要求、命令、建议等意义的动词后, that宾语从句中谓语常用“(shuld+)动词原形”, 表示虚拟。*The dctr suggested that I stay in bed fr three days. 医生建议我卧床三天。*He insisted that we stp at a small restaurant just utside f Atlanta. 他坚持让我们在亚特兰大市外不远的一家小餐馆歇歇脚。
【巧学助记】后接宾语从句常用虚拟语气的动词口诀: “一二三四”一个坚持(insist); 两个命令(rder, cmmand); 三条建议(advise, suggest, recmmend); 四项要求(demand, desire, require, request)
【即学活用】(1)He _______________________________.  他坚持要我看他的信。(2)I advise ____yu ______________yur cach _____yur ________and __________.  我建议你应该向你的教练咨询一下你的优缺点。(3)(2019·北京高考)He recmmended that ___________________.  他建议她做一些研究。
insisted that I shuld read his letter
(shuld) cnsult
she d sme research
三、表语从句(predicative clause )1. 表语从句放在连系动词之后, 充当复合句中的表语。表语从句的引导词有: (1)从属连词: that, whether, as thugh, as if, why, because 不充当任何成分, 只起连接作用(2)连接代词: wh, what, which , whm, whse, whatever, whever, whmever, whichever在表语从句中充当主语、宾语或表语(3)连接副词: when, where, why, hw, hwever, whenever, wherever在表语从句中充当状语
*The truble is that Henry has n qualificatins t teach cllege students. 麻烦的是亨利不具备教大学生的资格。*The pint at issue is whether we g t the party. 争论点是我们是否去参加聚会。*The last time we had great fun was when we were visiting the Water Park. 我们最后一次痛快地游玩是我们参观水上公园的时候。
2. 系动词be, appear, seem, lk, remain等之后可以跟表语从句。*It seemed as if he had knwn the fact already. 他好像早已知道这件事了。*It appears that sme missiles have been mved. 一些导弹似乎已经被移走了。*It lks as if she had just cme back frm uter space. 她看起来仿佛刚从外太空回来。
【名师点津】表语从句四点易错提醒(1)表语从句一定要用陈述语序。(2)不可以用if, 而用whether 引导表语从句。(3)that在表语从句中不可以省略。(4)主句主语是reasn时, 表语从句要用that引导, 不可用because。
【即学活用】(1)语法填空①The mst cmplex prblem is ____he can’t find enugh experienced players t engage in the game.  ②The reasn why I’m calling yu is ____I want t invite yu t my birthday party. ③All she’s wrried abut is _______his sn has the qualificatin t participate in activity.  ④This is _____we have been lking frward t fr years. ⑤ He has heart disease. That is _______he has been smking t much.
(2)The prblem is _____________________this shp.  问题是谁将接管这家店铺。(3)That is _____________________________jurnalism.  那时我才意识到新闻工作的重要性。
wh will be in charge f
when I realized the imprtance f
同位语从句　　同位语从句是用以解释说明某一名词内容和实质的从句。同位语从句一般跟在某些表示抽象概念的名词后面, 用以说明名词所表示的具体内容。可跟同位语从句的名词通常有advice, demand, dubt, fact, hpe, idea, infrmatin, message, news, rder, prblem, prmise, questin, request, suggestin, truth, wish, wrd(消息)等。
【名师点津】同位语从句和定语从句的区别定语从句是对先行词的修饰或限制, 属于形容词性从句的范畴; 而同位语从句是对前面抽象名词的具体内容的说明, 属于名词性从句的范畴。*The news that ur team has wn the game is true. 我们队赢了那场比赛的消息是真的。(同位语从句, 补充说明news到底是一个什么消息)*The news that he tld me yesterday was true. 昨天他告诉我的那个消息是真的。(定语从句, 关系代词that指代news, 在从句中作tld的宾语)
*(2019·江苏高考)Scientists have btained mre evidence that plastic is finding its way int the human bdy. 科学家已经获得更多证据, 塑料正在进入人们的体内。
【即学活用】(1)语法填空①(2019·天津高考)The pinin ____learning is a lifelng prcess has been expressed by educatin experts thrughut the years. ②The idea ____the gvernment wuld take ver driverless cars and treat them as a public gd wuld get abslutely nwhere here. (2)He ften asked me the questin ___________________________.  他经常问我为什么这项工作值得做。
