二、名词性从句(主语从句,表语从句,同位语从句,宾语从句) 连接词
That Whether/if
连接代词
Who/whoever Whom.whomever What/whatever Which/whichever
连接副词
When While As if
How/however
一、主语从句:
(1)、 that he told you everything is likely 主从放句首 =it is likely that he told you everything It做形式主语的主从 【常见形式】:It+主语谓语+连接词that+主从 1、be+adj
2、be+n词组:It is no wander that you are so tired
3、be+过去分词 :It is said that you have got the scholarship
此形式常与虚拟语气连考:It is said that+should do
(2)what 引导的主从:只放句首,不放句末。What只作主语/宾语/表语 与that作连词的区别:that不充当成分,只作连词。 例:what you said is true (what作宾语:you said what) What is worth doing is doing well (what作主语) (3)疑问词+ever+主从+主语谓语
无义 是否 内容 选择
主、宾、表 宾
主、宾、表、定 主、宾、表、定 状语 状语 状语 状语
不充当成分,只起连接作用
Whover did the job should be praised 主从
都不能换成no matter wh-的形式,此形
式不引导名从
I believe whatever you say 宾从
Whatever I say,they won’t listen to me 此乃让步状从,可以换成no matter wh- 二、同位语从句:由抽象名词引导
引导同从的抽象n:idea,opinion,advice,suggestion,doubt,order,news,fact,problem,
truth, belief,thought,answer,discovery,explaination,information,knowledge,promise,etc(此词乃等等= =)
【与定从的区别】:1、同从是解释说明n,定从是修饰限制n
2、同从that只起连接作用,不充当成分,无译意,不能省略,且从句中不缺成分 定从that一定充当主/宾/表,无译意,作从句宾语是可以省略,从句中缺成分 3、同从在特殊情况下会与所修饰词分离 Word can that……有消息传来 4、缺主语,又是物的时候用what引导 三、表语从句
I+be(系动词)+ 连词:that,whether
连接代词:what,who,whom 连接副词:where,when,why,how The future isn’t what used to be
The read measure of success is how happy you are
注:1、As if/as though也可引导表从
It seems as if it is hot
2、主语为reason是表从用that引导而不用why或because引导 The reason for her absence is that he go
