1It is/was + 被强调部分 + that/who 该句型是强调句型。被强调部分可以是主语,宾语,表语或状语。强调的主语如果是人,that 可以由 who 换用。如果把这种句型结构划掉后,应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。
一般陈述句:Tom bought a book in this bookshop yesterday
It is Tom who/that bought a book in this bookshop yesterday 强调主语
It is a book that Tom bought in this bookshop yesterday 强调宾语
It is in this bookshop that Tom bought a book yesterday 强调地点状语
It is yesterday that Tom bought a book in this bookshop 强调时间状语
2 It is not until + 被强调部分 + that 该句型也是强调句型。主要用于强凋时间状语,译成汉语 “直到……才……”,可以说是 not until 的强调形式。
It was not until she took off her dark glasses that I realized she was a famous film star 强调句
= Not until she took off her dark glasses did I realize she was a famous film star 倒装句
= I didn't realize she was a famous film star until she took off her dark glasses 一般句式
3 It is+形容词(clear /obvious/true/possible/certain…)+ that 从句 该句型中it 是形式主语,真正的主语是 that 引导的主语从句,常译为 “ 清楚(显然,真的,肯定……)”是主语从句最常见的一种结构。
It is very clear that he's round and tall like a tree
= That he's round and tall like a tree is very clear
4 It is+形容词(important /necessary/ right/strange/natural)+that 从句(should) do 该句型和上一个同属一个句型。由于主句中的形容词不同,that 后的从句中要用虚拟语气(should + 动词原形),should 可以省去。
It is necessary that we (should)learn a foreign language
是的
it 作形式主语,主要分为下列三种情况:不定式作主语、动名词作主语 和 名词从句作主语。具体分析如下
不定式作真正主语
主要用于下列句型:
⒈It + is/was + adj/n (形容词或名词) +to do sth
A 名词作表语。主要有a pity,a pleasure,an idea等。例如:
In fact________is a hard job for the police to keep order in an important football match (2001上海高考题)
A this B that
C there D it (答案为D)
动名词作真正主语
用于这种形式的是一些特定的形容词和名词。例如:
It was nice meeting you 见到你真高兴! (分别时用)
它与不定式作真正主语的区别在于,动名词说到的动作已经发生。例如:
It is nice to meet you (刚刚见面时用)
it 作形式主语,动名词作真正主语主要用于下列句型:
It's +n(名词或名词短语)/adj(形容词)+ doing sth
1)下列形容词后常用动名词作真正主语:nice,good,useless,hard,foolish,enjoyable,worthwhile等。例如:
It is nice talking to you 跟你交谈真是愉快。
It's foolish behaving like that 这样的表现是很愚蠢的。
It is useless doing that 那样做没用。
名词从句作真正主语
用it 作形式主语的结构主要用于下列句型:
It +谓语+名词从句(主语从句、表语从句、同位语从句)
⒈It is +名词+从句: 这样的名词有a fact,a surprise,an honor(非常荣幸),a pity,common knowledge(常识)等。例如:
It is common knowledge that the full moon brings fair weather 皓月兆天晴,这是常识。
举例如下:
it is important to keep calm when there is emergency
译文:发生紧急情况时保持冷静是很重要的。
it is nice to see you
译文:很高兴见到你。
学好英语的秘诀
第一:自信的说英语。英语是一门语言,最重要的事说出口,很多同学学习英语的时候不敢说出来,怕人家笑话,虽然学的很好,却成了“哑巴英语”。要想学好英语,那就勇敢自信的说英语,慢慢的锻炼中,英语语感有了,英语自然就学好了。
第二:经常的听英语。英语听力刚开始的时候确实是很痛苦的,听不懂,也做不对,就像放弃。其实只要坚持下去,在听的时候集中注意力,认真听,坚持一段时间就会收到很好的效果。
第三:慢慢的写英语。现在大部分的报纸,杂志都是英语版,工作中用英语写邮件也是家常便饭。那么要想学好英语还需要写英语。所有的英语就由26个字母组成,写英语的时候要慢,不要写成汉语式英语。特别是练习写作的时候,要慢慢的写,把每一个单词拼写正确,争取每一句语法都不会出现错误,慢工出细活。
it 在英语中可以做形式主语,可以代替那些成分?
it的用法总结:
1 可以做代词,指代无生命的东西或者不辨性别的人。
如: I bought a book yesterday, and I like it very much
whose baby is it
who are knocking at the door it's me
2 it做无人称代词,指代时间,距离,天气等。
如:it 's cold today it's nine o'clock it's a long way there
3 it做代词,在句子中做形式主语和形式宾语。
如: it took me 3hours to finish the work
I don't think it a good idea to stay here just waiting
It可以做什么的形式主语通常用it 做形式主语,将不定式和动名词置于谓语后面,特别是主语较长时,或在一些习惯用法中。
1) 谓语是系表结构(be + 形容词 / 名词)时,常将不定式后置,构成句型 “it + be + 表语(形容词 / 名词)+ 不定式”。
例 1 It is my duty to care for that patient
照料那位病人是我的职责。(做主语的不定式to care for that patient 后置,it 为形式主语)
例 2 It is not an easy thing to master a foreign language
掌握一门外语不是件容易的事。
例 3 It isn’t right to speak ill of someone behind his back
在别人背后说坏话是不对的。
2) 当谓语是 take,make,pay,cost ,require, feel,need 等动词时,或者是与情绪有关的动词 delight,amuse,excite,annoy,irritate 等时,习惯上常用 it 做形式主语,并将不定式后置。
例 1 It takes only ten minutes to get there
到那儿只需十分钟。
例 2 It pays to be honest
诚实是不会吃亏的。
例 3 It feels good to stay away from the crowded city
能远离拥挤的城市,感觉真不错。
例 4 It annoyed her to see someone spit on the ground
看见有人随地吐痰让她很生气。
3) 同不定式一样,动名词也可用于“it + be + 表语 + 动名词”句型中,二者的区别可参见10.2.2 中1)的论述。下面两组句子没有多大差异。
例 1 A) It is a waste of time to argue with him
B) It is a waste of time arguing with him
和他争辩是浪费时间。
例 2 A) It is worthwhile to discuss this again
B) It is worthwhile discussing this again
这一点值得在讨论一下。
4) 但表语是(of)no use,not any use,not the slightest use, no good, not much good,fun等时,常用动名词(不用不定式)做主语并后置,用 it 做形式主语。
例如 It’s no use crying over spilt milk
覆水难收。
5) 动名词还可在 there be 句型中做主语(不能用不定式),常见形式为 “there is no + 动名词”或 “there is no / any + 名词 + 动名词”。
例 1 There is no denying the fact
事实无可否定。
例 2 There isn’t any use trying again
再试也没用。

英语中那些词性可以做主语那些不能1 名词做主语:
Our school is not far from my house
2 代词做主语:
We like our school very much
3 数词做主语:
Two plus o is four
4 名词性或名词化的词、词组或短语:
This is an article
5 动名词做主语:
Seeing is believing
6 动词不定式做主语:
To do such a job we need a better knowledge
7 从句做主语:
What I mean is to work harder
8 名词做主语:
The mother with her child is ing to the school
形式主语只有一个it 吗?有没有其它词可以做形式主语?当代英语中,通常用it 做形式主语,将不定式和动名词置于谓语后面,特别是主语较长时,或在一些习惯用法中。
1) 谓语是系表结构(be + 形容词 / 名词)时,常将不定式后置,构成句型 “it + be + 表语(形容词 / 名词)+ 不定式”。
例 1 It is my duty to care for that patient

掌握一门外语不是件容易的事。
例 3 It isn’t right to speak ill of someone behind his back

5) 动名词还可在 there be 句型中做主语(不能用不定式),常见形式为 “there is no + 动名词”或 “there is no / any + 名词 + 动名词”。
例 1 There is no denying the fact
事实无可否定。
例 2 There isn’t any use trying again
再试也没用。
PS最后一项中关于there be的句型,其实there be 只是倒装用法而已,不是there作形式主语
There 是不是也可以做形式主语?不行,做形式主语的只能是it
上面那个句子只是个There be 句型
英语中什么成分可以做状语?
副词
介词短语
从句
以上是 经常 作状语 的
另外还有相当于 副词的 词
不定式
现在分词
过去分词
另外 还有
形容词短语
名词短语如 heart and soul/ day and night
单个的名词 不能作状语
有时单个 的形容词 可以。如he came back happy
现在分词 如 he walked along the river ,singing过去分词 the teacher walked out of the class room ,followed by the students with 的复合结构 he slept,with the window open 独立主格结构 the room is on the sixth floor ,its window facing the north形容词 短语 也可以 he walked in the street ,cold and hungry he was back home ,happy and gay
英语中doing(一类词)可以做主语,那么done可以吗doing可以但done不能 To be done
那些词可以做形式宾语it可以指代learning English well这个动名词短语,也可以是一个宾语从句的引导词;而在第二个例子里面,it是虚拟主语,那么important的后面就只能跟不定式,而不能跟动名词短语了。
嘿嘿,其实语法这种东西很活的,我上中学的时候一直搞不清楚状语和定语的区别,甚至连定语从句都不知道是什么含义,但是我的英语成绩一直是班上第一。所以,英语不能学死了,语言是活的~~更重要是语感,而不是形式化的语法。
在英语中,副词可以做宾语吗不可以 宾语必须是名词性的词 如 名词 代词
动词不定式,动名词或主语从句作主语时,通常把它们放在谓语动词前,而用it作形式主语,放到句首,常见句型有:
1 It + be + 形容词+主语从句,如:
It is uncertain whether he can come to Jenny’s birthday party or not
2 It + be + 名词词组 + 主语从句,这类名词有:a fact, a pity, a shame, an honour,a question等,如:
It’s a pity that you missed the exciting football match
It remains a question whether he will come or not
3 It + be + 过去分词 + 主语从句,这类过去分词有:announced, believed, expected, hoped, decided, reported, said, shown等, 如:
It is reported that 16 people were killed in the earthquake
It is not decided who will give the operation to the patient
4 It + 不及物动词(seem, appear, happen等) + 主语从句, 这类不及物动词有:appear, happen, seem等, 如:
It seemed that he didn’t tell the truth
It happened that I was out when he called
5 It + be + 形容词 + for sb)+ 动词不定式
这类句型常用形容词easy, difficult, hard, important, possible,wise等作表语,有时候为了强调不定式动作的执行者,常在不定式前加for sb,如:
It’s necessary for the young to master two foreign language
It is unwise to give the children whatever they want
这类形容词有:easy, difficult, hard, important, possible,wise
6 It + be + 形容词 + of sb + 动词不定式,这类形容词常是表示心理品质,性格特征的形容词,如:kind, nice stupid, clever, foolish, polite, impolite, silly, selfish, considerate等。某人和这些形容词可以构成主系表结构。如:
It’s very kind of you to help me with the work=You are kind to help me
It seemed selfish of him not to share his dictionary with others=He seemed selfish not to share his dictionary with others
7 It + be +名词词组 + 动词不定式,如:
It is not a good habit to stay up too late
8 It + be + 名词或形容词 + 动名词,这类名词和形容词常常是:good, no good, no use, a waste of, useless, senseless等,
如:
It’s a waste of time talking to her any more
It is no use arguing about the matter with him
9 It + take ( sb )+ 时间(金钱)+ 动词不定式,如:
It took the workers almost three years to finish building the dam
It will take a whole day to get to the top of the mountain on foot
这要根据具体情况,用" 助动词的肯定式或否定式+it " 来反问同样遵循"前肯后否,前否后肯"的反问原则如:
It's difficult to learn English ,isn't it
It takes them 20 minutes to get to school every day ,doesn't it
It's not your fault to miss the film ,is it
以上就是关于it用作形式主语代替动名词主要用于哪些句式全部的内容,包括:it用作形式主语代替动名词主要用于哪些句式、it做形式主语和形式宾语的用法句型、是不是所有用it 做形式主语的句子他们的真实主语都在后面变句子的时候只需将后面的句子提前啊等相关内容解答,如果想了解更多相关内容,可以关注我们,你们的支持是我们更新的动力!
