引导名词性从句的关联词

引导名词性从句的关联词

引导名词性从句的关联词在传统的语法中,有连接代词、连接副词和关系代词、关系副词之分;连接代词、连接副词引导名词性从句和关系代词、关系副词引导定语从句。

本书根据最新资料不再作此分类,通称关系代词和关系副词。

引导名词性从句的关联词大致相同,它们分别是:连词:that, whether, if;关系代词:who, what, which , whom, whose, whatever, whoever, whomever, whichever;关系副词:when, where, how, why,however, whenever, wherever。

引导从句时一般不用逗号和主句分开。

最新名词性从句引导词表格

最新名词性从句引导词表格

一、名词性从句的引导词:(一)常见的酸和碱1、酸的通性(1)酸溶液能跟酸碱指示剂起反应。

紫色石蕊试液遇酸变红,无色酚酞试液遇酸不变色。

注意显色的物质是指示剂。

(2)酸能跟多种活泼金属起反应,通常生成盐和氢气。

只有位于金属活动性顺序表中氢前面的金属才能与稀酸(HCl、H2SO4)反应,产生氢气。

位于氢后的金属不能与稀酸(HCl、H2SO4)反应,但能与浓硫酸和浓硝酸反应。

例如:①Cu+2H2SO4(浓) CuSO4+SO2↑+2H2O②3Cu+8HNO3(稀)=3Cu(NO3)2+2NO↑+4H2O可见,金属和浓硫酸、硝酸反应都没有氢气产生,这就是实验室不能用浓硫酸和硝酸与锌反应制氢气的原因。

(3)酸能跟碱性氧化物反应生成盐和水:H2SO4 + CaO == CaSO4 + H2O(4)酸能跟某些盐反应生成新酸和新盐:H2SO4 + BaCl2 === BaSO4↓+ 2HCl(5)酸跟碱起中和反应生成盐和水:H2SO4+Ba(OH)2 === BaSO4↓(白色沉淀)+2H2O常见的酸有盐酸、硫酸和硝酸,它们虽然具有上述五点通性(因为电离出的阳离子都是H+)。

但又各具不同的物理化学性质。

①盐酸是氯化氢的水溶液,是一种混合物。

纯净的盐酸是无色的液体,有刺激性气味。

工业品浓盐酸因含有杂质(Fe3+)带有黄色。

浓盐酸具有挥发性,打开浓盐酸的瓶盖在瓶口立即产生白色酸雾。

这是因为从浓盐酸中挥发出来的氯化氢气体跟空气中水蒸汽接触,形成盐酸小液滴分散在空气中形成酸雾。

②硫酸是一种含氧酸,对应的酸酐是SO3(SO3+H2O==H2SO4)。

纯净的硫酸是没有颜色、粘稠、油状的液体,不易挥发。

常用的浓硫酸中的H2SO4的质量分数为98%,密度为1.84克/厘米3。

稀H2SO4具有酸的通性。

浓硫酸除去具有酸的通性外,还具有三大特性:a、吸水性:浓H2SO4吸收水形成水合硫酸分子(H2SO4•nH2O),并放出大量热,所以浓硫酸通常用作干燥剂。

名词性从句与连接词(用法讲解)

名词性从句与连接词(用法讲解)

语法专题 1
名词性从句与连接词
主语从句、宾语从句、表语从句和同位语从句在复合句中的作用相当于名词,因此这四种从句统称为名词性从句。

我们根据从句应用的位置,可基本判定从句的类型: ①That/Wh-(主语从句)+ v. …
②It (形式主语) + v. …+ that/wh-(主语从句) ③… + vt. + that/wh-(宾语从句) ④… + prep. + that/wh-(宾语从句) ⑤… + be/系动词 + that/wh-(表语从句) ⑥(… +) n./pron. + that/wh-(同位语/定语从句) ⑦状语从句 ,S + P (主句)
⑧S + P (主句) ,状语从句/非限制性定语从句
从句要用陈述语序,即:连接词 + S. + V .。

引导名词性从句的连接词有三类:从属连词、连接代词和连接副词。

(1)、从属连词
它们在从句中只起连接作用,不充当任何成分。

(2)、连接代词 (wh-引导的从句原来是特殊疑问句,wh-引导词很多还保留着原来在疑问句中疑问的含义) 它们都有各自不同的含义,除了起连接作用外,还在从句中充当主语、宾语、表语或定语等成分。

(3)、连接副词 (
wh-引导的从句原来是特殊疑问句,wh-引导词很多还保留着原来在疑问句中疑问的含义) 它们也都有各自不同的含义,除了起连接作用外,还在从句中作状语。
