【生成·得】名词性从句在句中的作用相当于名词,可作主句的主语、表语、宾语和同位语。因此,名词性从句可分为_________、_________、_________和___________。
【研学·析】 Ⅰ.引导名词性从句的连接词1.连接代词:wh, whse, whm, what, which。有词义,在从句中可以作主语、表语、宾语或定语等。 2.连接副词:when, where, why, hw。有词义,在从句中作状语。 3.连接词:that, whether, if, as if。that 无词义,在从句中不作成分,有时可省略;if (whether), as if虽有词义,但在从句中也不作成分,但不可省略。
Ⅱ.主语从句1.在复合句中作主语。 ①_____ we need is mre time and mney. 我们所需的是更多的时间和金钱。 ②________ he’ll cme here isn’t clear. 他是否会来这里还不清楚。③_____ this happened is nt clear t anyne. 这是怎样发生的,谁也不清楚。④________ cmes is welcme. 不论谁来都欢迎。
2.为了避免句子头重脚轻,常用it作形式主语,代替主语从句放在句首,而把主语从句置于句末。常用句型有:(1)It + be +形容词+ that 从句;(2)It + be +名词+ that 从句;(3)It + be +动词的过去分词+ that 从句等;
(4)在表达惊异、惋惜、建议、要求等意义的主语从句中常使用虚拟语气,即(shuld )+动词原形,主句中的谓语动词形式不限。①It is said ________________________________(格林先生已经到北京了). ②It is a pity that _________________________(我们昨天晚上没有见过面).  ③It is imprtant that ________________________________(我们先把功课学好). ④It’s suggested that _________________________________________(我们要保护这条河流不被污染). 
that Mr Green has arrived in Beijing
we shuld nt meet last night
we shuld d well in ur lessns first
we shuld prtect the river frm being plluted
Ⅲ.宾语从句1.宾语从句在复合句中通常作动词或介词的宾语。 ①I wnder _____ he’s writing t me abut. ②Yur success will largely depend upn _____ yu d and ____ yu d it. ③I’m interested in _______ yu’ve finished the wrk.④I knw _____he is frm the suth.
2.掌握宾语从句应该注意的几个问题:(1)that不能省略的情况:and或 but连接两个或多个宾语从句时,可以省略第一个连词that,and或者but的后面的that不能省略;作介词宾语时,不能省略;主句谓语动词与that从句之间有插入语时不可省略。 (2)宾语从句的时态变化规律:主句是一般现在时态时,从句可根据需要用任何时态;主句是一般过去时态时,从句使用过去的任何时态。但客观真理除外。(3)whether与if引导宾语从句时,下面情况不能互换: 宾语从句是否定句时只用if,不用whether;与r nt 连用时只用whether;介词后的宾语从句要用whether引导。同时whether 可与不定式连用,可引导主语从句、表语从句、同位语从句,if则不能。
(4)advise, demand, desire, insist, rder, prpse, request, suggest表示请求、要求、命令或建议等意义的动词所接的宾语从句一般用虚拟语气,即(shuld) +动词原形。①They dn’t knw _______ t g there. ②I dn’t knw __ yu can help me. ③The teacher said the earth ____(g) rund the sun. ④She tld us that she __________(help)a lt f peple. ⑤The teacher advised that we ___________(make) gd use f every minute here. 
Ⅳ.同位语从句1.同位语从句用来对其前面的抽象名词进行解释说明,被解释说明的词和同位语在逻辑上是主表关系。先行词通常为fact, belief, news, idea, infrmatin, dubt, questin, reprt, decisin等。如果先行词是表示请求、要求、命令、建议等的名词,如:advice, desire, prpsal, recmmendatin, request, requirement, suggestin,同位语从句的谓语动词用虚拟语气,即(shuld) +动词原形。
①The news _____________________(他健康状况不佳) made us sad. ②The questin _____________________(谁该干这项工作) requires cnsideratin. ③There is n dubt ________________________(他会再来这里). ④I have n idea __________________________________(他们在哪里度假). 
that his health is failing
wh shuld d the wrk
that he will cme here again
where they are spending their hlidays
2.掌握同位语从句的用法应注意以下两个问题:(1)为了保持整个句子的结构平衡,同位语从句与它所说明的名词隔开;(2)同位语从句和定语从句结构相似。但是,同位语从句相当于名词的作用,而定语从句相当于形容词的作用。同位语从句对名词加以补充说明,定语从句对先行词加以限制或修饰。that引导同位语从句时不作句子成分且不可省略;引导限制性定语从句时作主语、宾语或者表语,作宾语时经常省略。
①We’re interested in the news that sme freigners wuld visit ur schl.( )②The news that he tld us surprised us.( )③I wn’t believe the fact that he tld me.( )④I wn’t believe the fact that he lied t his mther.( )⑤I have n idea where he has gne.( )⑥G and get yur cat. It’s in the place where yu left it.( )
【内化·用】 用适当的连接词填空。①_____ he finished writing the cmpsitin in such a shrt time surprised us all. ②His father is wrried abut _______ he will lse his wrk.③He tld me ____ he wuld g t Shanghai the next day.④I have n idea _____ he will cme back hme.
常温故·勤总结名词从句有四种, 主宾表同在其中;主从连接很重要, 先定主“谓”是首要;主宾表全选副词, 主宾表缺选代词;that从句表事实,连接从句无意义;which范围有限定,what范围常不定;whether“是否”在其中,主宾表同都可用;if主宾限定有,表同从句不可有;because从句表原因,why从句表结果;从句用法记心中,填空造句很轻松。
