名词性从句经典1
名词性从句经典1一、名词性从句1．_____Macao has achieved shows _____"one country, two systems" principle is the best solution to the Macao and Hongkong question, left by history.A. That; whatB. What; thatC. What; whatD. That; that【答案】 B【解析】【分析】句意：澳门取得的成就表明，“一国两制”原则是解决历史遗留下来的澳门和香港问题的最好办法。
分析句子可知，_____Macao has achieved为主语从句，从句中achieve缺少宾语，所以第一个空用what来充当宾语。
再分析句子可知，shows后接宾语从句，从句句意和结构完成，所以第二个空应填连接词that。
故选B。
【点评】考查名词性从句，本题涉及what引导的主语从句和that引导的宾语从句。
2．It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories.A. what thatB. whichC. thatD. that what【答案】 D【解析】【分析】句意：有人指出，驱除焦虑所起着至关重要的作用是童年美好的回忆。
本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。
名词性从句讲义1
名词性从句讲义一. 名词性从句在句子中起名词性作用的从句叫做名词性从句(Noun Clauses). 名词性从句在句中的作用相当于名词或名词短语, 在复合句中担当主语, 宾语, 表语和同位语等. 因此根据它在句中不同的语法功能可分为: 主语从句, 宾语从句, 表语从句和同位语从句.引导名词性从句的连接词可分为三种:连接词: that, whether, if (不在从句中做任何成分)连接代词: what, who, whom, which, whose和wh+ever (通常在从句中做主语,宾语,表语等) 连接副词: when, where, why, how以及wh/h+ever(通常在从句中做状语)二.主语从句1.概念: 主语从句是在复合句中充当主语的从句.2.连接词:that只起连接主句和从句的作用,在从句中不担任任何成分,本身没有词义,不可省略whether 连接主句和从句, 在从句中不担任任何成分, 但本身有选择或是否的含义whether与if 区别〔一〕引导宾语从句，一般既可用whether 也可用if。
但1 or not放在whether之后时，只能用whether 不用if。
I don’t know whether or not he will come. 我不知道他是不是回来。
注1：如果or not放在whether所引导的从句句尾，那么可以用if来替换。
I don’t know whether/if he will come or not.我不知道他是不是回来。
2 在强调任意选择时,用whether…or,此时不用if替换whether。
He asked me whether I wanted to go there by train or by bus.他问我是想乘火车还是坐公共汽车去那里。
注：whether和or一起还有“不管〞之意,引导让步状语从句。
Whether he drives or takes the train, he will be here on time.不管开车来还是乘火车来，他都会准时到。

5. “疑问词+ever” whatever, whichever, whoever, whomever 引导宾语从句 I’ll show you whatever you want to see. He likes to makes friends with whoever shares his interest.
二、注意正确使用时态
1. 如果主句是一般现在时、一般将来时或祈使句时，宾 语从句时态不受限制 I hear he is here today/ he was here yesterday/ he will be here tomorrow. 2. 如果主句是一般过去时，宾语从句应与主句保持一致， 即使用过去时态的某种形式。 He said he was watching TV/ he had swept the floor/ he would play football after school. 3. 如果宾语从句所叙述的是客观事实、自然现象、科学 真理等时，从句不受主句限制，用一般现在时。 Everyone answered there are sixty minutes in an hour.
• 2.引导主语从句的词： • 连词：that, whether
起连接作用不充当成分
• 连接代词：what(ever),who(ever), which(ever)，whose,
充当主语/宾语/定语等
• 连接副词：when, where, how ,why
充当状语表时间、地点、方式、原因
连接副词：when, where, how ,why引导的主语从句
1.I hear (that)___________.(一小时后会回来)
2.He said (that)___________.(他非常想我们) 3.The teacher told us (that)_____________. (地球围绕太阳转）

2.名词性从句的连接词名词性从句通常由一个连接词和主句相连。
连接词很重要，它既是联系主句的纽带，又是从句的标志，通过连接词，我们可以辨认不同从句的性质。
一．从属连接词（在从句中不充当任何成分，只起到连接从句的功能）A．that 只是引导名词性从句，本身并没有实际意义，在从句中不充当任何句子成分。
That he will come to the meeting is certain.(主语从句)The fact remains that we are behind the other group.(同位语从句)B．if和whether具有“是否”的意义，但是whether比较正式，在口语中人们经常if, if 和whether在名词性从句中尽管不充当任何的成分，但不可以省略。
C．whether不能替代if的情况1.if只能引导宾语从句（做介词宾语的情况除外），而whether 可以引导所有的名词性从句。
She asked if/ whether that was enough.Whether the football match will be played depends on the whether.The question is whether we can arrive there on bus.2.whether引导宾语从句做介词的宾语，if没有这种用法It depends on whether it will be fine.3.whether后紧跟不定式He was wondering whether to go home.4.or not 可直接跟在whether后面，但不可以直接跟在if后面。
