代词、It的用法

一、代词考点透析

1．人称代词的主格、宾格，两种物主代词及反身代词。

人称代词的主格在句中作主语，宾格作宾语。形容词性物主代词作定语，即其后必须有一个名词。名词性物主代词在句中的作用相当于一个名词，可作主语、宾语、表语等，其后没有名词。反身代词在主语、宾语、表语后作这些成分的同位语，意为“亲自”、“亲眼”、“某某本人”。在语法填空中，这个知识点出现的频率相当高。如：

(1)It was John himself that put him in trouble

是约翰本人自找麻烦。

(2)You can believe meI saw it myself．

你可以相信我，我亲眼看见的。

2．one，ones，the one，that，those可以代替前面出现的名词，以避免重复。one＝ a＋名词单数，the one＝the＋名词单数，that＝the＋名词单数。ones，those代替前面的名词复数，those ＝the＋名词复数。one，ones前可以有形容词修饰。如：

(1)I don't like this skirtI like the red one

我不喜欢这条裙子，我喜欢那条红色的。

(2)I'm planning to buy a houseI'd like one with a garden

我正计划买房子，我想买座带花园的。

(3)The population in Guangzhou is bigger than that in Changsha

广州人口比长沙多。

(4)I prefer the apples in the basket to those in the box

我宁愿要篮子里的苹果，也不愿要那些盒子里的苹果。

3．none，nothing，nobody(no one)的区别。

none既可指人，也可指物，且表特指概念，回答how many，how much等问题；nobody(no one)只能指人，且表泛指概念，常回答who引起的问题；nothing只能指物，常回答what引起的问题。另外，no one后不带of短语，none后可带of短语。

4．few，a few，quite a few，many修饰可数名词；little，a little，quite a little，much修饰不可数名词。

5．another，the other，others，other，the others的区别。

another泛指另一个；the other特指两个中的另一个；others泛指“其他”，后不带名词；other后带名词复数；the others指特定范围中其他的人或物，后不带名词。如：

(1)This coat doesn't fit meWill you show me another

这外套不合身，请拿另一件给我看看好吗？

(2)Thirty students in our class are girls，and the others are boys

我们班三十人是女生，其余的是男生。

6．注意下列句型：

Onethe other

一个……另一个……

Someothersand still others

有的……有的……还有的……

7．not 与all，everybody，everyone，everything等连用，或“not every＋名词”结构，都表示部分否定。如：

(1)Not all the students agree with this opinion

并非每个学生都同意这个观点。

(2)Not everyone is interested in football

并不是每个人都对足球感兴趣。

(3)Not every boy likes smoking

不是每个男孩都喜欢吸烟。

8．everyone表示某一范围内的每个人，anyone意为任何人。如：

Everyone of Class 17 is for the idea to go outing

17班的每个人都赞成郊游。

Anyone with common sense knows it is impossible

任何有常识的人都知道这是不可能的。

学习IT技术可以终生就业吗？作为就业行业的热门词条，IT行业的就业率始终高扬，而其失业率却非常的少。甚至有说法认为IT行业是可以终生就业的行业。这究竟是为什么？

关于这个问题，北京北大青鸟的老师这样解释。

第一点，在目前IT行业大发展的情况下，IT行业的人才缺口还在扩大，几乎每个合格的IT技术人才都会被市场吃进。只要学的专业符合市场需求就不用担心找不到工作。

第二点，IT行业是一个宽就业的行业。因为IT行业的大发展，如今已经成为了一个相当庞大的产业，需要各种类型的人才。粗略划分有7大类，IT产品设计人员、IT产品开发人员、IT产品销售推广人员、IT产品服务支持人员、解决方案集成设计人员、IT产品施工人员及IT产品使用人员。这7类人覆盖了从专业的软件开发企业到使用这些软件的各类大中型企业，甚至延伸到一些有办公自动化、无纸化需求的企事业单位。门门种种不一而足。

第三点，IT行业是技术+经验的行业。在工作经验不断积累的过程中，IT行业的从业者也在不断地升值。无论是软件开发还是网络维护，从业者应对各种困难的能力以及 *** 作先进设备的能力都是一笔可观的财富。在经验不断积累的过程中，你的工资也会水涨船高。

第四点，IT行业是一个可以不断学习和提升的行业。相对于制造业等传统的工业，IT技术的延续性、继承性更强。到目前为止，每一项IT技术的进步都是在前一项技术上升级和加强，技术原理可以一通百通。相对于其他行业的新技术会更易学，掌握也更快。保证了从业者可以很快地接受新技术跟上技术革新的步伐而不被淘汰。

it引导主语从句和it做形式主语还有强调句型的区别

“it”引导主语从句和“it”做形式主语还有强调句型的区别：

it引导的主语从句，形式主语就是it，真正的主语在句子的后面，通常是to do的不定式短语。

而强调句的结构 it is/was+被强调部分+that/who+句子其余部分，结构词it is/was和that/who都是没有实际意思的，只是构成句子结构的词而已。这个强调句只能强调名词和代词，也就是主语和宾语，不能强调其他句子成分。

强调句：It is you who help me with my housework

it 做形式主语时、句子是主语从句么？

形式主语是动词不定式的一种,它也是逻辑主语, 可以把它归类到逻辑主语的第一种(不定式的逻辑主语) 用作宾语的不定式，用作目的状语，用作结果状语的不定式都是属于不定式的大概念里面的。 形式主语it 作为形式主语的it并无实际语义，只是为满足语法上的需要，避免句子头重脚轻，它代替 的是句子的逻辑主语，概括起来会有如下情况： 句子的逻辑主语为不定式 如：It is very kind of you to give me a hand in time It is my pleasure to address the meeting It was pretty hard for him to bring up the child on his own 句子的逻辑主语为从句 如：It so happened that the tickets were sold out It is extremely obvious that she has been lying about her identity It suddenly ourred to me that the message must have been hidden beeen the layers of the briefcase 句子的逻辑主语为动名词短语 这类句子远不如前面两种出现率高，主要在（no good, waste, useless, no use, dangerous）等词语的后面用 如：It is no use reasoning with him It is no good reading in dim light 作形式主语的代词只能用it ，不能用that，this等词。例如: 1) It is easier to lose friends than to make friends 交朋友难而失去朋友比较容易。 2) It is important for modern young people to master at least o foreign languages 掌握至少两门外语对于当代年轻人来说是很重要的。 以上两句中的it是形式主语，真正的主语是后面的不定式短语。 3) It is considered no good reciting without understanding 不理解的背诵被认为是没有好处的。 4) It is no use crying over spilt milk 覆水难收。 以上两句中的it是形式主语，真正的主语是V-ing形式。 5) It is a fact that English is being aepted as an international language英语作为一门国际语言正日益为人们所接受，这是不争的事实。(NMET,95) 6) It depends on the weather whether we will go 我们去不去得看天气行事。(其中的whether 不能换成if,因为if不能引导主语从句。) 以上两句中真正的主语是名词性从句。 it 作形式主语主要用于下列三种情况不定式作真正主语 主要用于下列句型： 1 It + 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) 再如： It is a great pleasure to do this 这样做多好啊。 It is a good idea to think this way 这样考虑问题是个好办法。 除be外，其他动词也有跟名词的情况。例如： It seems a pity to waste the food 浪费这些食物真可惜。 It requires efforts to master a foreign language 掌握一门外语需要种种努力。 B 形容词或形容词短语作表语。 分两种情况： 1) 下列形容词： kind, good, nice, clever, wrong, right ,foolish, wise, unwise, stupid, rude, careless, cruel, brave, naughty, polite, selfish等词作表语时，不定式前常可加一个由of引起的短语，来说明不定式指的是谁的情况。形容词表示不定式逻辑主语的特征，即形容词用来描述不定式行为者的性格、品行等。例如： It was foolish of you to leave school你中途退学，真是傻瓜。 It was brave of her to speak out in public 她能当众大声讲话，真勇敢。 这种of to do sth 句型，of 的宾语可以作句子的主语。上面两个句子可以改写为： You were foolish to leave school She was brave to speak out in public 2) 其他形容词作表语，常见的形容词有：necessary, hard， important, difficult, easy, possible，mon等。例如： It is necessary to use a short-wave radio to pick up the programmes 必须用短波收音机才能收到节目。 如果要说明不定式表示的动作是谁做的，可以在不定式前加for + 名词或代词 + to do sth(for 后的宾语不能作句子的主语)。名词或代词作不定式的逻辑主语，即表示不定式所指动作的执行者。在此句型中，形容词只对不定式行为者作某种描述，而不涉及其品行。例如： It is not hard for one to do a bit of good 对于一个人来说做点好事并不难。 It,s mon for leaves to fall from the trees in the fall 秋天树叶从树上落下是件常事。 需要注意的是：动词不定式作主语，一般情况下用it作形式主语，而把动词不定式(从句)放在后面。也可以直接用不定式作主语。例如： It is wrong to tell lies = To tell lies is wrong 撒谎是不对的。 但在疑问句和感叹句中，只能用it作形式主语。 例如： Isn't it a good idea to have a walk around 出去兜一圈难道不是一个好主意吗？ What a pleasure it is to work with you! 同你一起工作是多么愉快啊！ 2 It + v + to do sth 动词不定式作主语时除动词be以外，动词take, cost， need, require, make, sound, our 等也可用it作形式主语，而把动词不定式放在后面。例如： It took us three years to plete the project 我们花费三年时间才完成了这项工程。 It sounds reasonable to do it this way听起来这样做有道理。 It needed hard work to finish the job 要完成这项工作需要努力地工作。 It didn,t our to me to ask him to help me 我根本没想到要找他帮忙。 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。 2)下列名词或名词短语作表语时常用动名词作真正主语：use, good, fun, a waste of, job, task等。例如： It's a waste of time doing this 这样做是浪费时间的。 It's no good (use) doing that 那样做没好处(没用)。 It's an awful job doing this 做这事真是一件可怕的差事。 It's fun doing this 做这事真有趣。 It is not an easy task doing this work 做这工作真非易事。 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) 1 It is +名词+从句: 这样的名词有a fact, a surprise, an honor(非常荣幸),a pity, mon knowledge(常识)等。例如： It is mon knowledge that the full moon brings fair weather 皓月兆天晴,这是常识。 It is a surprise that you gave such an answer to the question 你对这个问题作了这样的回答，令人吃惊。 2 It is +形容词+从句 : 这样的形容词有natural, true, strange, necessary, important, obvious(很明显), certain, wonderful, funny, possible, likely, probable等。例如： It is certain that free medical care will be given to most people in our city 我们城市的多数人将享受免费医疗，这是一定的。 It is probable that he has known everything 很可能他什么都已经知道了。 3 It +动词+从句: 这样的动词有seem,happen, appear, look, matter, make, strike, our(突然想起)等。 It appeared that he had a taste for music 看来他对音乐有一定的鉴赏力。 It made us very happy that she was saved她能化险为夷令我们大家很高兴。 4 It + be + 分词+从句: 这样的分词有 said(据说)， reported(据报道),believed(人们相信)，known(众所周知)，decided(已决定)，proved(已证实), thought, expected, annouced, arranged, amusing, puzzling, striking等。例如： It is said that Li Hao has been to Europe据说李郝去过欧洲。 It was amusing that a rabbit ran out of the empty box on the desk桌上的空盒子里竟然跑出来一只兔子,太有趣了。 需要说明的是，大部分连线词引导的主语从句都可以用 it充当形式主语。例如： It remains unknown when they are going to get married 他们何时结婚依然不明。 It says in the newspaper that the enemy has been defeated 报纸上报导敌人被打败了。 形式主语： It +be+(the)+adj+for +to do sth

IT行业是大家众所周知的黄金行业，换而言之，也就是10个人里，可能有7个人会选择进入IT行业，因为工作环境本身好，基本上没什么体力劳动，办公室作业，并且工作的大环境也比较公平，有能力者居上，想要靠裙带关系，很多时候也只是想想，这是个凭真材实料才可以进入的行业。

随着我国信息化的建设，IT行业的贡献是越发的大，IT行业的增长速度也是大家有目共睹的，并且从最新出炉的2016年行业平均薪资排行榜中，也证实了IT行业在当下的地位，因为IT行业已经超越金融行业成为榜首，所以IT行业已经成为很多年轻朋友不二的选择，觉得未来IT行业就是他的奋战场。

IT行业如此受欢迎，自然是一件好事情，但是是所以的IT岗位都缺人吗那么自然是不一定的，有的IT岗位是早已饱和的。2023IT行业中什么人才最紧缺Java人才。根据相关统计数据显示，我国IT编程人才目前仍有近百万的缺口，而其中很大部分即为软件测试人才和软件开发人才，软件人才正在成为我国IT行业目前最紧缺的人才之一。

随着软件开发产业的迅猛发展，Java行业人才需求量也在逐年扩大。据国内权威数据统计，电脑培训发现未来五年，对软件开发人才需求将超出上百万，甚至还每年递增20%的速度增长，而Java软件开发人才所占需求比例为60%-70%，Java人才缺口巨大，Java人才月薪过万。
