高中英语名词性从句精讲

高中英语名词性从句精讲从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。
在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
在句子中起名词作用的句子叫名词从句(Noun Clauses)。
名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、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类:(1)从属连接:that, whether, if(不充当从句的任何成分)(2)连接代词:what, whatever, who, whoever, whom, whose, which.(3)连接副词:when, where, how, why名词性从句知识点汇总1名词性从句的分类名词性从句,包括四种从句,即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成,所以这四种从句在主句中都充当了名词的作用,故将这四种从句统称为名词性从句。
如:1.That she will help me made us happy.(主语从句)2.I can understand what he said.(宾语从句)3.This is where I was born.(表语从句)4.The fact that a heavy earthquake happened made me crazy.(同位語从句)2名词性从句的连接词分类1.that(无含义,不充当成分)2.whether,if(有“是否”的含义,但不充当成分)3.连接代词:what, whatever, who, whoever, whom, whomever, whose, which, whichever.(在从句中做主语、宾语、表语和定语)连接副词:when, whenever, where, wherever, how, however, why (在从句中做状语)4. as if,as though,because(不充当成分,在名词性从句中只引导表语从句)3连接词 that 在名词性从句中可以省略的三种情况1.it 做形式主语,that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。
高中英语语法:四种名词性从句讲解与练习

名词性从句名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。
因此,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。
引导词:主语从句就是在复合句中用作主语的从句,引导主语从句的引导词主要有三类:一是that;二是whether;三是那些可以用作疑问词的词语,如what, who, which, when, where, how, why等(一)引导名词性从句的连接词1、连接代词:who, whose, whom, what, which。
有词义,在从句中担任成分,如主语、表语、宾语、或定语等。
2、连接副词:when, where, why, how。
有词义,在从句中担任成分,作状语。
3、连接词:that, whether, if, as if。
that 无词义,在从句中不担任成分,有时可省略;if (whether), as if虽有词义,但在从句中不担任成分。
注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。
连接代词与连接副词在从句充当句子成分,连接词whether 和if(是否),as if(好象)在从句中不充当句子成分,只起连接作用。
根据句义,如果连接代词与连接副词,whether、if 和as if都用不上时,才用that作连接词(that本身无任何含义)。
一、主语从句与宾词从句连词、语序、时态相同。
只是不能用if, that 不可省;(一)、主语从句是一个句子,在句子中作主语成分。
(二),主语从句的特点1.与宾语从句使用同样的连接词,只是if 不能用;1)、陈述句用that。
2)、一般疑问句用whether。
3)、特殊疑问句用特殊疑问词what, which, who,when, where, why, how 等词引导。
2.经常隐身(以it为形式主语出现)。
例句:1.It's true that the earth is round.That the earth is round is true.2. 表是否的意思时,不能用if代替whether.It hasn't been decided whether he'll come or not.Whether he'll come or not hasn't been decided.3. 从句语序为主谓宾正常语序。
