2、连接词名词性从句主要有四种结构:以that引导的从句;以whether/if引导的从句;以特殊疑问此引导的从句;以what或wh-ever等连接的从句。
此外,as if,as though,because,as也可以引导表语从句。
(1)从属连接词引导名词性从句的从属连接词主要有that,whether,if。
○1That只起连接主句和从句的作用,在从句中不充当任何成分,也无词义。
○2whether/if起连接主句和从句的作用,在从句中不充当任何成分,本身有词义,表示“是否”。
(1)特殊疑问词○1连接代词:who,whom,whose,what,which。
起连接主句和从句的作用,在从句中充当成分,本身有词义。
○2连接副词:when,where,how,why。
起连接主句和从句的作用,在从句中充当成分,本身有词义。
(3)名词性关系从句:○1连接代词:whoever,whomever,whatever,whichever。
○2连接副词:whenever,wherever,however。
(4)从属连词as if,as though,because,as引导的表语从句。
连接词的用法1、thatThat只起连接主句和从句的作用,在从句中不充当任何成分,也无词义。
(1)主语从句○1可用it作形式主语,从句本身置于句末,常见的句型有:A、It+形容词+ that从句It is clear that he was telling the truth.B、It+名词词组+that从句It is a pity that you can’t go with us.C、It be+过去分词+that从句It’s said/reported/believed/thought/expected thatIt’s said that he has been there many times.D、It+及物动词+宾语+that从句It worried her a bit that her hair was turning grey.It shocked me that he didn’t tell anybody where he was.E、It seems/happens/appear等不及物动词+that 从句It seems that he was lost something.○2在口语和非正式文体中,that常可以省略,尤其实在非常短的句子中,that是不必要的;但that从句位于句首时,连词that是不可以省略的。
It’s a pity(that)you are leaving.That we are invited to the concert this evening is good news to us.2、宾语从句○1常见的可以接从句作宾语的动see,say,know,discover,believe,tell,show,think,consider,sure等,在可以接复合宾语(宾语+宾补)的动词后,如think, make, consider等,可以用it 作形式宾语,而把真正的宾语从句后置,that 在这种情况下不能省略。

3、表语从句that不可以省略。
这种从句往往对主句的内容起进一步解释作用。
其基本结构为“主语+系动词+ that从句”。
My decision is that all of us are to start at 6 o’clock tomorrow.4、同位语从句that不可省略。
如果同位语从句意义完整,应用that引导同位语从句。
5、whether/if(是否)起连接主句和从句的作用,在从句中不充当任何成分,本身有词义,表示“是否”。
(1)主语从句若句中需要表达“是否”意思时,则用whether/if。
当主语从句放在句首时,只能用whether 引导,不用if 引导;当it作形式主语,主语从句放在句末时,whether和if均可以用。
Whether the meeting will be given is still a problem.It’s doubtful whether/if he will come here.(2)宾语从句whether/if引导的宾语从句:作“是否”讲,常用在ask,care,find out,know,wonder等动词之后引出带有疑问意义的宾语从句。
从句仍保持陈述语序,whether或if 不当成分。
I wonder if/whether he can come tomorrow.。
