什么是名词性从句?在英语的句子结构中,本来该由名词充当的主语、宾语、表语和同位语,由一个句子来充当,这个句子就叫名词性从句。
Related Cnceptin (相关概念)
1.名词 : 表示人或事物的名称的词叫名词。
2.名词在句子当中一般可以作什么成分?
名词在句中主要作主语、宾语、表语和同位语。
The by is li Ming.
Mr. Liang , a 24-year-ld by, teaches us English.
主语从句 ( The Subject Clause)宾语从句 ( The Object Clause)表语从句 ( The Predicative Clause)同位语从句 ( The Appsitive Clause)
Find ut & Underline & Recgnize
What he had said surprised everyne present.We discussed whether we shuld use the mney t buy a new huse. The mst pleasant thing f the rainy seasn is that ne can be entirely free frm dust.
主语从句 ( The Subject Clause)
宾语从句 ( The Object Clause)
表语从句 ( The Predicative Clause)
主语从句是指在句中作主语的从句,位置与陈述句的主语相同。Whether the sprts meet will be held is nt certain nw. That he had met a kind librarian in the city library gave us n surprise.若主语部分结构较长,可以使用 形式主语 it ,把真正的主语从句放于后面。That she will d well in her exam is certain.= It is certain that she will d well in her exam..
形式主语就是形式上的主语,而真正的主语往往在句子的靠后位置避免“头重脚轻”的不平衡现象,从而影响表达效果。用法:把真正的主语放在句子尾部,来保持句子的平衡美感。 明德中学赢了,就是那个里面有陈xx、洪xx、寇xx、刘xx、邱xx,还有流川枫的那支队伍。 明德中学,就是那个里面有陈xx、洪xx、寇xx、刘xx、邱xx,还有流川枫的那支队伍,赢了。
宾语从句是指在句中作宾语的从句,位置与陈述句的宾语相同。Everyne knws that the earth is made up f matter. I dn't knw where I can place my luggage. I'm nt certain whether the train will arrive n time..
当主句主语是I 或we, 谓语动词是think, believe, suppse, expect等时,其后的宾语从句若是否定句,否定词要前移到主句上,即I/We dn’t think/believe/suppse/expect…
I dn't think we need t waste much time n it.
主句,dn’t think为否定前移
省略了that的宾语从句
I dn’t think he can cme this evening.我认为他今晚不会来。
表语从句是指在句中作表语的从句,位置与陈述句的表语相同。实际上是对主语进行补充说明,从句表达的是主语的内容。he fact is that he didn't ntice the car until l late. The mst pleasant thing f the rainy seasn is that ne can be entirely free frm dust.
什么是虚拟语气?虚拟语气主要体现在动词的时态变化上,常用于表达主观的愿望、假设以及推测等等。比较典型的情况是:对已经发生的事实进行虚拟假设。(比如“如果昨天我没有吃麻辣烫的话”)或者假设一种不大可能发生的情況(比如”如果能够回到过去〞)并且以这种虚拟的假设条件为基础,进行推导得出虚拟的结果或结论。例如:A. 如果昨天我没有吃麻辣烫的话,可能就不会长痘了。B. 如果能够回到过去,我想回到16岁。主句的主语是名词 idea、 advice、 suggestin、 rder、request、 requirement等时,表语从句应用虚拟语气,即谓语动词用“(shuld+)动词原形”。My suggestin is that we(shuld) have a discussin abut this matter.
1、连接词thatthat引导从句时,本身无意义,在从句中不充当成分。在引导宾语从句时,常被省略;但是that在引导主语从句、表语从句时,一般不能省略。That he suddenly fell ill made us surprised. She said that she wuld cme here. The fact is that we are behind ther grups.
1. that、 whether 和 if
已确定的事由that引导;没决定的事由whether、if引导.
思考一下:哪个句子的that可以省略呢?
2、连接词whether、ifwhether、if 引导从句时,在从句中意为“是否”,不充当成分,一般不能省略。在主语从句中位于句首时只能用whether;当用it作形式主语时,whether与if都可以。 Whether he passed the exam was nt certain.= It was nt certain whether/if he passed the exam.在表语从句中常用 whether。The questin is whether we shuld ask them fr help.
2、连接词whether、ifwhether、if 引导从句时,在从句中意为“是否”,不充当成分,一般不能省略。宾语从句中连接词 whether 和 if 常常可以互换。I wnder whether / if he'll agree with me.宾语从句中用 whether不用 if 的三种情况:(1)与 r nt连用We dn't knw whether Tm will tum up at the meeting r nt. (2)位于介词之后Everything depends n whether yu are fr it.(3)位于动词不定式之前I dn't knw whether t believe him.
连接代词what、 which、wh、whm和whse在从句中起代词的作用,可作主语、表语、宾语或定语。 That's what we have said.Wh will cme t give the talk is knwn t us all.The prblem is whm the headmaster will send t deal with it.特殊考点 1:连接代词what、which的区别特殊考点 2:连接代词what、that的区别
2. 连接代词what、which、wh、whm 和 whse
连接代词what、which 的区别:which 引导主语从句时需要限定一个有限的、较小的范围what 指在一个较广的范围内进行选择或者根本没有范围。______ f the bys brke the windw is already knwn.I dn't knw ______ bks the children can read.
连接代词what、that 的区别:what 引导主语从句时在从句中充当句子成分,如主语、宾语、表语;而 that 则不然。________ yu said yesterday is right.________ she is still alive is a gd thing.
when 意为“何时” , 在从句中作时间状语where 意为“哪里” , 在从句中作地点状语hw 意为“如何” , 在从句中作方式状语why 意为“为什么”,在从句中作原因状语When we'll set ff fr hme hasn't been decided yet.That was where I spent my hliday. Nbdy knew hw she gt the prize. This is why we put ff the meeting.
3.连接副词 when、 where、why 和 hw
连接代词whatever、whichever、whever和whmever在从句中的意义分别为“无论什么”、“无论哪一个”、“无论谁”在从句中起代词的作用,可作主语、宾语或定语。Whatever I have is at yur service. I'll take whichever picture yu dn't want. Whever breaks the law shuld be punished.Whmever yu invite will be welcme.
4.复合连接词 whatever、whichever、whever 和 whmever
1. he will cme here n Wednesday is certain.2. The questin is the film is wrth seeing.3. The reasn I have t g is my mther is ill in bed.4. he will cme here n Wednesday is nt certain.5. It is a pity we can’t g.6. That‘s he is wrrying abut.
