‎2013届高三英语语法要点精讲(配最新高考+模拟)‎ 专题14 it的用法 ‎【考纲解读】‎ 根据近向几年高考试题来看,it一直是考查的重点,尤其是it, that 和one不同的指代功能。试题注重情景的设置,需要利用特点语言环境中上下文的联系,正确分析结构,理解句意是做此类题目的关键。 ‎ 命题的热点集中于以下几个方面: . ‎ ‎1. it/that/one用法区别(it主要指代前面提到的同一物;one用来指代前面出现的单数名词,相当于a/an+单数名词,表泛指概念,往往是同类而同一物;that用来替代前面出现的特指的单数可数名词或特指的不可数名词,相当于the+单数/不可数名词)‎ ‎2. it用在某些动词后,如:enjoy,like,,dislike,resent,hate,don’t mind,be fond of,feel like,see to 之后, 即这些动词后面的宾语从句前要加it代替其后的从句 ‎3. 用于强调句或固定句型(it is/was …when/since/before…)中. ‎ ‎4. 作形式宾语或形式主语(主要代替ving,to do或从句)‎ ‎5. 考查it 构成的习语,it也常表示抽象的情况,属于虚指. 如:Take it easy.‎ ‎【知识要点】‎ It的用法 ‎(一)作人称代词 ‎ 1、it代替前面(或后面)的单数名词或分句等所表示的事物。‎ ‎ e.g. You cannot eat your cake but have it.(it代替前面的cake)‎ ‎ Although we cannot see it, there is air all around us. (it代替后面的air)‎ ‎ They say he has left town, but I don’t believe it. (it代替前面They…town分句中的情况)‎ ‎2、代替有生命但不能或不必分阴阳性的东西(包括婴儿)。‎ e.g. Yesterday we saw a big tree. It was fully twenty metres high. (it代替前面的tree)‎ ‎ The baby cried because it was hungry. (it代替前面的baby)‎ ‎ 3、在某些习惯说法中,可以代替人。‎ ‎ e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me.‎ ‎ ---- Who are singing? ---- It is the children.‎ ‎ ---- The light is still on in the lab. It must be the third-year students doing the experiment.‎ ‎ 4、it与one的区别:这两个词都可以代表前面说过的名词,但it用于同名同物的场合;one则用于同名异物的场合。‎ ‎ e.g. ---- Do you still have the bicycle? ---- No, I have sold it.‎ ‎ ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk.‎ ‎ 5、it与that的区别:两词都可代替某一特定名词,但that指同一类,并非同一个。‎ ‎ e.g. The climate of South China is mild(温和的); I like it very much.(it指the climate of ‎South China)‎ ‎ The climate of South ‎China is much better than that of Japan.(that指the climate)‎ ‎(二)作无人称代词 ‎ it作无人称代词时,除了句中找不到它所代表的词语外,另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。‎ ‎ It is fine (rainy, windy, etc.).‎ ‎ It is noon.‎ ‎ It is a half hour’s walk to the factory.‎ ‎ It is eighteen square metres in area.‎ ‎ What does it matter?‎ ‎(三)作强调词,构成强调结构 ‎ 用以帮助改变句子结构,使句子的某一成分受到强调。“It is (was) + 所强调的成分 + that (who) + 其它成分。”在这个句型中,it本身没有词义。注意:‎ ‎ 在强调结构中,如被强调部分为时间状语或地点状语,其后的连接词也绝不能为when 或where,而应用that 。在复习中,一定要注意句式的不同。‎ It was in Shanghai that I bought the guitar.(that引起强调句)‎ It was Shanghai where I bought the guitar.(where引起定从)‎ It was twelve o'clock when we arrived there.(when引起时间状语从句)‎ It was at twelve o'clock that we arrived there.(that 引起强调句)‎ ‎(四)引导词it作形式主语(宾语)‎ ‎ 为了使句子平衡,常采用形式主语(或宾语)it ,而把真正的主语(或宾语)置于句子后面。通常引导词it与它所代替的句子成分中间要夹有某些词。‎ ‎ e.g. It takes half an hour to go there on foot.(It与to go there on foot之间夹有takes half an hour四个词) We thought it strange that Mr Smith did not come last night. (it与that从句中间夹有 strange)‎ ‎ 但有时it与所替代部分之间并不夹有其它词。‎ ‎ e.g. You may depend on it that they will support you.(因为介词on之后一般不直接接that引导的宾语从句。注意:it不是多余的,不能当作错句)‎ ‎(五). it,one,that 的区别:作为代词,这三个词的对比使用是高考的热点之一。‎ ‎---Why don't we take a little break? ---Didn't we just have __________?‎ A.it B.that C.one D.this ‎ The Parkers bought a new house but _________will need a lot of work before they can move in.‎ A.they B.it    C.one D.which ‎ one 用以指代同类事物中的任一,that 特指性强,指代可数与不可数词,而it指代上文提过的同一事物。‎ 一、代词it 用 法 例 句 代替前文提到过的东西或事情,用作人称代词。‎ This is a new dictionary. I bought it yesterday.‎ 这是一本新词高考资源网典,我昨天买的。‎ Tom joined the army last mouth. Do you know about it?‎ 汤姆上月入伍了,你知道这事吗?‎ 代替指示代词,起着this或that的作用 Is this your car? No, it isn’t. 这是你的汽车吗?不是。‎ What’s that?—It’s a video. 那是什么?它是一台录像机。‎ Whose room is this?—It is theirs.这是谁的房间,是他们的。‎ 指明某人或某物的身分,还可指不明性别的婴儿 Who’s there? It’s me. (It’s John) 谁在那儿?是我。(是约翰)‎ Go and see who it is that rings. It’s Bill.‎ 去看看是谁来的电话,是比尔。‎ The Greens have a new baby. It’s lovely.‎ 格林家有一个新生婴儿。它很可爱。‎ 指时间,距离,自然现象(天气,气候,明暗)量度,价值等 It’s Sunday today. 今天是星期天。‎ It’s three months since he came here.‎ 自从他来到这里,已经三个月了。‎ How far is it to the Great Wall .到长城有多远?‎ It’s getting dark. 天快黑了。‎ ‎—How much is the coat? —It’s ninety dollars.‎ 这件衣服多少钱?九十美元。‎ 二、引导词it 用 法 例 句 形 式 主 语 代替不定式短语 It is up to you to decide. 这事要由你决定。‎ It makes me happy to hear you have recovered.‎ 听说你恢复了健康,这使我很高兴。‎ 代替动名词短语 It’s no good smoking. 吸烟没有好处。‎ It’s worthwhile working the whole night on the problem.‎ 用整夜的时间来研究那个问题是值得的。‎ 代替主语从句 It doesn’t matter what you do. 你干什么都没有关系。‎ It seems that everyone has known the news.‎ 好象大家都知道这个消息。‎ 形式 代替不定式短语 I consider it better to be early.‎ 我认为能够早一些更好。‎ We found it impossible to get there before July .‎ 我们觉得,要在七月以前到达那里是不可能的。‎ 宾语 We thought it no use doing that.‎ 代替动名词短语 我们认为做那事没有用。‎ 代替宾语从句 The teacher makes it clear that everyone should hand in his homework on time .‎ 老师清楚地指出,每个人都应该按时交作业。‎ 三、it在强调结构中 强调句型:It is (was) +被强调部分+ that (who) + 其它 强调 部分 例 句 说 明 主 语 It is I who am to blame. 是我该受责怪。‎ It was your uncle that (who) came yesterday. ‎ 昨天来的是你叔叔。‎ 原句的谓语动词如果是现在或将来时态用It is …that(who)如果原句谓语动词是过去时态,则用It was…that(who)。在 宾 语 It was a new pen that Mother gave me .‎ 母亲给我的是一支新钢笔。‎ 强调时间,地点,原因或方式时不要用when, where, how, 必须用that。‎ 地点 It was in the classroom that I left my umbrella.‎ 我把雨伞就落在了教室里。‎ 状 语 时间 It is at eleven that the train leaves.‎ 火车是在十一点钟离开。‎ 方式 It was just as he ordered that I acted.‎ 我正是照他吩咐的那样做的。‎ 原因 It was because he was in trouble that I tried my best to help him.‎ 正是因为他处境困难我才尽力帮助他。‎ 宾 补 ‎ It was red that we painted the gate.‎ 我们把门油漆成红的颜色。‎ It was chairman that they elected him .‎ 他们选他担任的是主席的职务。‎ ‎【考点诠释】‎ 考点 it的用法 在英语中,运用it的场合较多。从它在句中的作用和意义来看,it的用法可分为三类:‎ ‎1.指代作用 ‎(1)用作人称代词,代替前文或后文所提到的同一事物(单数可数名词或不可数名词)。如:‎ Although we cannot see it,there is air all around us.虽然我们看不见空气,但它却在我们的周围。‎ ‎(2)代替前面的整个句子。如:‎ It is said that he has died of a disease,but it isn’t true.据说他已经病死了,但这不是真的。‎ ‎(3)用在答语中代替指示代词this,that。如:‎ 一What is this?这是什么?‎ 一It’s a bike.是自行车。‎ ‎(4)代替不能或没有必要区分性别的或某些习惯说法中的人。如:‎ ‎①The baby cried because it Was hungry.婴儿哭是因为饿了。(婴儿习惯上不区分性别)‎ ‎②一Who is knocking at the door?谁在敲门?‎ 一It’s me.是我o ‎(5)指环境、情形等。如:‎ ‎①I can’t stand it any longer.我再也不能容忍这种情况了。‎ ‎②Take it easy.别紧张。‎ ‎③It doesn’t matter.没关系。‎ ‎(6)指度量衡单位、时间、距离、季节、天气及自然现象。如:‎ ‎①It’s getting colder and colder now.现在越来越冷了。‎ ‎②It is winter now.现在是冬天了。‎ ‎2.形式作用 ‎(1)形式主语 当动词不定式、v.ing形式或从句作主语时,通常把它们放在谓语之后,而用it作句子的形式主语。如:‎ ‎(I)It’s no use crying over spilt milk.[谚]覆水难收。‎ ‎②It takes three generations to make a gentleman.[谚]十年树木,百年树人。‎ ‎ (2)形式宾语 当复合宾语中的宾语是不定式、v-ing形式或宾语从句时,往往把真正的宾语放在补足语后面,而用it作形式宾语,放在宾语补足语之前。如:‎ ‎①You must make it clear to them that the situation is serious.你必须向他们表明形势是严峻的。‎ ‎②)They thought it difficult to talk to the guests about the recent events.他们觉得和客人们谈近来发生的事情很困难。‎ 特别提示 形式宾语用在“主语+谓语动词+宾语”结构中,谓语动词appreciate,dislike,hate,like,love,make(按时到达,成功)等后接由if或when等引导的从句时,往往在从句前加形式宾语it。如:‎ ‎①1 would appreciate it if you paid in cash.如果你能支付现金的话,我会不胜感激。‎ ‎②The boy likes it when you do that.那个男孩喜欢你那样做。‎ ‎3.强调作用 it可以用来改变句子的结构,使句子的某一成分得到强调。强调句型的基本结构为:It is/was+所强调的成分+that/who/whom+其他成分。‎ ‎【试题放送】‎ ‎1. 【2012·金华十校期末】—Do you allow smoking in the office?‎ ‎ —No.______ smoking here will be fined.‎ ‎ A.Whoever B.Anyone C.Who D.Anyone who ‎【答案】B ‎【解析】考查代词。空格后的smoking 作定语,相当于who ‎ smokes,所以只能用anyone,语境为:任何一个在这里吸烟的人都要被罚款。‎ ‎2. 【2012·顺义素质展示】 — Have you got any idea for the summer vacation?‎ ‎— Yes.
