it的用法讲解---绝对经典系列

“it”还可以用来指代不明身份的人。
比如有人敲门,你不知道是谁,就可以问:“Who is it?”(是谁?)当“it”表示时间、天气、距离、温度等抽象概念时,也有着独特的作用。

例如,“It is difficult to learn a foreign language”(学习一门外语很难。
)这里真正的主语是“to learn a foreign language”,“it”只是形式主语。
再比如,“I find it hard to understand this question”(我发现理解这个问题很难。
)此句中,“it”是形式宾语,真正的宾语是“to understand this question”。
“it”还用于强调句型“it i s/was +被强调部分+that/who”中。
通过这种句型,可以强调句子中的主语、宾语、状语等成分。
比如:“It was Tom who broke the window”(是汤姆打破了窗户。

考研英语语法点:It专题

考研英语语法点:It专题2022年考研英语语法点:It专题熟悉真题的同学们肯定知道,it在英语中尤其是阅读和翻译中往往作用巨大。

如下,凯程考研英语教研室彭佳洁老师为大家介绍it的几种用法。
指代性it一般是指人称代词it,it作人称代词时可指代事物、动物、婴儿、未知的人或一件事。
例句1:It’s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. 这句话中第二个it就是指代前面的theory。
这是一个许多经济学家赞同的理论,但是在实际中,它往往会使得铁路处于一个决定哪些公司会兴旺,哪些公司会衰败的地位中。
例句2:Until these issues are resolved, a technology of behavior will continue to be rejected, and with it possibly the only way to solve our problems. 在这句话中,it指代a technology of behavior will continue to be rejected 这一情况。

考研英语语法点:It专题
熟悉真题的同学们肯定知道,it在英语中尤其是阅读和翻译中往往作用巨大。
It分为两种情况,一种是指代性it,另一种则为非指代性it。
如下,跨考教育英语教研室彭佳洁老师为大家介绍it的几种用法。
指代性it一般是指人称代词it, it作人称代词时可指代事物、动物、婴儿、未知的人或一件事。
例句1:It’s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. 这句话中第二个it就是指代前面的theory。

第二种情况是非指代性it。
非指代性it是相对于作人称代词的it而言的。
他们往往没有具体意义上的主语,它用于表示气候、温度、时间、地点、距离等。
非指代性it常作seem, appear, look, happen, occur, follow等动词的主语,构成特定的句型。
例句:From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years.这句中it没有实际意义,为非指代性用法,that引导表语从句。
从热点人口分析中可以看出,非洲板块是静止不动的,而且在过去的三百万年中也从未移动过。
当然,在考研考试中,it的重难点更加具体和明确。
it 做先行词。
it做形式主语或者形式宾语。
It作形式主语时,往往放在句首,将真正的主语(动词不定式、动名词、从句)放在之后。
其中it可作形式主语指代不定式,这时常见的谓语有:take, pay, make, cost, require, feel, annoy, need等。
另外,it形式主语指代It形式主语指代从句,而且主要形式为It is+a.+than; It is+n.+that; It
is+done+that; It+vi+that;
例如:It is difficult to the point of impossibility for the average reader under the age of forty to imagine a time when high-quality arts criticism could be found in most big-city newspaper.
It做形式宾语是放在谓语动词与宾语补足语之间,指代不定式、动名词、从句等。
后接it作形式宾语的谓语动词有:feel, consider, find, believe, make, take, imagine, suppose, think, deem, regard, count等。
引导强调句的it。
同学们所熟悉的强调句型中,它的基本形式就是“it+be的某种形式+that/who从句”。
当被强调部分是人时须用who, 其他情况用that。
例句:Curbs on business-method claims would be a dramatic about-face, because it was the Federal Circuit itself that introduced such patents with its 1998 decision in the so-called State Street Bank case, approving a patent on a way of pooling mutual-fund assets. 在because从句中就运用了it was ….that的强调句型,强调部分为the Federal Circuit itself. 对商业方法专利申请的限制将会是一个巨大的改变,因为这些专利正是联邦巡回法院自己在1998年审理一个被称作“美国道富银行”的案件时提出的,判决中巡回法院批准了一项共同基金资产集资方法的专利。
