it is sure that 是 it 引导结构吗,sure不是形容词并做表语吗?求解析此句结构

是主语从句。不用虚拟语气。在主语从句中, 为了防止句子头重脚轻,通常把形式主语it放在句首位置,真正主语搁置于句末用it作形式主语的结构,如下:
1、主语从句常用it作形式主语,一般常用句型为:It is+{名词/形容词/过去分词}+主语从句。
2、强调句则不同,它的结构是:It+be+被强调部分+that+从句。
3、It is +名词+that从句。
4、It is +形容词+that从句。
5、It +不及物动词+that从句。
6、It is+过去分词+that从句。
扩展资料一、主语从句不可位于句首的五种情况:
1、if引导的主语从句不可居于复合句句首。
2、It is said , (reported) …结构中的主语从句不可提前。
3、It happens…, It occurs… 结构中的主语从句不可提前。
4、It doesn’t matter how/whether …结构中的主语从句不可提前。
5、含主语从句的复合句是疑问句时,主语从句不可提前。
二、What与that在引导主语从句时的区别: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。
三、宾语从句用以区分主语从句的几个特征:
1、引导词:what\which\whose\when\whether\if\where
2、宾语从句必须是用陈述语句。(名词性从句都是陈述语序)。
i am sure 我确信,确信后面跟的是具体内容,在句子中作宾语,所以是宾语从句。如果不加从句,后面可以跟介词和宾语,I am sure of his arrival.
【转】It is certain that ...和It is sure that...的区别It is…that结构中只能用certain,不能用sure。Sure与certain是近义词,均作“一定的,确信的”等解。两者用法相似,多数情况下可换用,但有时不能换用。其用法区别大致如下:
一、 两者可换用的情况:
1. 跟不定式,可用人或物作主语。例如:
It is sure/certain to rain.
He is sure/certain to come.
You’re sure/certain to be happy with them.
2.跟连接代/副词引起的不定式,常用人作主语。例如:
I’m not sure/certain what to do.
He was not sure/certain when to start.
3.跟of或about引起的短语。sure后可跟of doing sth. 常用人作主语。例如:
I’m not sure/certain of that.
Are you sure/certain about it?
I’m sure of his coming.
He’s sure of winning.
注:sure to do sth.与sure of doing sth.的区别:前者表示说话者认为“主语一定…”;后者表示“主语自认为一定…”。例如:
He is sure to succeed. (说话者认为“他”一定会成功。
He is sure of succeeding. (“他”自己认为一定成功)
4.跟that引起的从句,常用人作主语。例如:
I’m sure/certain that he’ll come.
I was sure/certain (that) he had seen me.
I’m quite sure/certain I left the book on the table.
注:当sure或certain用于否定句时,其后跟whether或连接代/副词引起的从句,不跟that引起的从句。例如:
I’m not sure/certain whether I’ve met him before.
I’m not sure/certain whether he will come.
I’m not sure/certain who he is.
I was not sure/certain what I ought to do.
I’m not sure/certain why he wants it.
以上几种情况中的sure与certain虽可换用,但隐含意思不同。Sure表示主观的推测或感觉,所述事实并不一定如此;certain则指说话者有充分的理由或根据,肯定某事会发生。如下面两句中的certain均不可用sure替换。例如:
I’m certain he wasn’t in the classroom. I saw him in the library.
I’m certain than he will go the concert. He told me so an hour ago.
5.与make连用构成短语,后跟从句,作“弄清楚;设法做到”解。例如:
Make sure/certain when the train leaves.
Have you made sure/certain that the train has already left?
6.与for连用构成短语,在句中作状语。作“确实;毫无疑问”解。例如:I don’t know for sure/certain that he’s dead.
I cannot sau for sure/certain when he will come.
二、 两者不可换用的情况:
1. 在“It is…that结构中只能用certain,不能用sure。例如:
It is certain that he will come.
It was certain that our football team would win the game.
如是否定句,用whether,不同that。例如:
It is not certain whether he will come.
2. 在祈使句中通常用sure,不用certain。例如:
Be sure to tell me all the news.
Be sure and come as soon as possible.
Be sure you don’t upset any of them.
3.作定语时,sure作“有把握的;肯定的;可靠的”解;certain作“某个;某些”解。例如:
Put it in a sure place.
There was only one sure way to succeed.
A certain person called on me yesterday.
Certain students have failed in the exam.
4.Sure在美语中可用作副词作肯定答语,用以代替surely,相当于certainly,of course;而certain则不能用作副词。例如:
I wonder if I could use your phone.
Sure. Go ahead.
Zhou Lan, can I have a look at your copy of China Daily?
Sure, go ahead.
答:It为形式主语,指代that 后引导的内容:如:It's sure that he will not come.肯定他是不会来的。(这是肯定的,他不会来。)
sure是形容词,做表语。
it 是引导结构 代替后面的句子成分 sure 在这里是形容词 并作 is 的表语
形如 It is sure that he will win the game.意为 他肯定会赢这场比赛的。
做表语没错呀,it做形式主语。that引导的句子做真正主语,所以这句就是主语从句。
it is sure that ...恐怕是不地道的说法,老外这样说吗
可查词典验证-----找不到这样结构的句子
可说 it is certain that 取代之
除非意思是 it 指童话中的拟人化动物 它感到有把握。。。
词典只有one thing is [for] sure
没有it is sure that...的句型

郴彬盐酸: 一般是不会用it is sure that这样的表述形式的,但是有的时候表示“XXX很确认这件事情”的话就会用XXX is sure that... it is certain that XXX就是意为“XXX这件事情是真实的/确实发生了” 望采纳~

郴彬盐酸:[答案] 这就是一种特殊的表语从句!有的语法书上这样写,有的干脆不写,因为实在没有意义讨论这到底是什么从句.你要一定要问... 不是宾从,因为没有动词或介词 不是同位从,没有名词 不是主从.如果句子是It is sure that那是主从,但是这和你说的不一样...
