1、考点45 语法填空(二)第三部分 特殊句式及固定搭配专题一 特殊句式考点一 倒装句1.在英语中,把谓语全部放在主语之前的倒装句,称为完全倒装句。常见的完全倒装句有以下几种:在there引导的句子中,谓语是be, exist, live, lie等表示状态的动词时,用完全倒装句。地点状语位于句首,主语为名词且谓语为不及物动词时,用完全倒装句。作表语的形容词、分词或介词短语置于句首时,用完全倒装句。表示地点和动作转移的副词,如:here, there, up, down, in, away, out等置于句首且主语是名词时,句子用完全倒装。注意:当主语是代词时,不倒装。如: Here comes
2、the bus./Here it comes.2.在英语中,把助动词、情态动词或be动词移到主语之前称为部分倒装。常见的部分倒装句有以下几种:当so/neither/nor位于句首时,可将其后的部分谓语置于主语之前,构成部分倒装。only+状语/状语从句位于句首时,主句中的主语和谓语要部分倒装。表示否定意义的副词或介词短语放在句首时要部分倒装。此类副词或介词短语主要有not, little, hardly, never, by no means, on no condition, in no case, nowhere, seldom, nor等。在含有had/were/should的虚拟条件
3、句中,可以省略if,将 had/were/should放在主语之前,构成部分倒装。hardly.when., no sooner.than., not only.but also.等引导两个分句,且hardly, no sooner, not only等提到句首时,前一个分句用部分倒装,后一个分句不变。在so.that.句式中,如果so引导的部分位于句首,主句中的主语和谓语需要部分倒装。as/though引导的让步状语从句中,将表语置于句首构成部分倒装。Only when he reached the tea-house _he realize it was the same place he
4、d been in last year. 【解析】分析句子结构可知,此处应该填助动词did,构成倒装句。句意:只有当他到达茶馆时,他才意识到他去年也来过这家茶馆。only修饰状语从句when he reached the tea-house放在句首,主句要用部分倒装语序,根据语境为一般过去时,所以填助动词did。【答案】did考点二 强调句强调句型的基本结构为:It is/was+被强调部分+that/who.。在这个句型中,it没有词汇意义,只是引出被强调的成分。如果被强调的成分是表示人的词,用who或that来连接都可以。如果是其他成分,则一律用that来连接。被强调部分错综复杂
5、,容易与其他从句混淆。区分的方法是把句中的It is/was和that/who去掉,如果句子成立,且句意通顺,就是强调句型,否则就不是强调句型。如:It is Jane that/who has been living in London since she left China.去掉It is和that/who,还原为Jane has been living in London since she left China.作为句子完全成立,由此可以判断该句为强调句型。使用强调句型的几个注意事项:(1)被强调成分是主语,who/that之后的谓语动词应该在人称和数上与原句中的主语保持一致。It
6、is I who am right. 对的是我。 It is he who is wrong.错的是他。 It is the students who are lovely.可爱的是学生们。(2)被强调成分即使是在句子中作时间状语、地点状语、原因状语等,也不能用when, where, because,而要用that。It was after the war was over that Einstein was able to come back to his research work again.正是在战后爱因斯坦才得以重返研究工作。It was in front of the bank
7、that the lady was robbed.那位女士是在银行前面遭遇抢劫的。It was because of the heavy rain that he came late.他是因为下大雨来晚的。 (3)被强调成分是作主语的代词时用主格,是作宾语的代词时用宾格。It was he that helped me yesterday.昨天是他帮助了我。It was me that he helped yesterday. 他昨天帮助的是我。(4)被强调部分既包括人又包括物,用that不用who。It was the things and people that they remember
8、ed that they were talking about.他们谈论的是他们记得的人和事。【易混易错】强调句型与主语从句、状语从句、定语从句的区别1.强调句型与主语从句的比较 强调句型将句子中的it is/was与that/who同时省去,句子仍然成立;而包含主语从句的句子用that从句代替it,句子成立。如:It was Li Leis brother that you met in the street yesterday.你昨天在街上遇到的是李雷的哥哥。 (本句若将It was 及that同时省去为:You met Li Leis brother in the street yest
9、erday.句子同样成立,因此本句是强调句型。)It is exciting that we have succeeded in sending up Shenzhou X.我们成功地发射了神舟十号这件事情真令人兴奋。(本句若将It is 及that同时省去为:We have succeeded exciting in sending up Shenzhou X.显然句子错误,因此,本句不是强调句型,that引导主语从句,it是形式主语。)2.强调句型与定语从句的比较 强调句型中的it没有实际意义,it is/was与that/who去掉后句子结构仍然完整。但定语从句中的it be和作主语的t
10、hat去掉后句子结构不完整。3.强调句型与状语从句的比较 强调句型中的it is/was与that/who同时省去,句子仍然成立;而包含状语从句的句子it是主语。如:It was 8 oclock when they went home.他们回家时是8点。 (句中代词it作主语,指代时间,when引导时间状语从句)It was at 8 oclock that they went home.他们是在8点回家的。 (本句是强调句型,at 8 oclock是被强调部分)It was not until near the end of the letter _ she mentioned her o
11、wn plan. 【解析】分析句子结构可知,此处构成not until的强调句型,应填that。句意:直到将近信的结尾她才提到自己的计划。本题为强调句型,被强调部分为not until near the end of the letter。原句为:She didnt mention her own plan until near the end of the letter.。【答案】that考点三 祈使句_(knock) at the door before you enter my room, please. 【解析】分析句子成分可知,空格前没有主语,后面有before引
12、导的时间状语从句,由此可判断,此处构成祈使句,所以填knock。【答案】Knock专题二 固定搭配考点1 常见词组as a matter of fact;be proud of; by the way;come from;according to;congratulate.on.;devote.to.;earn ones living;keep ones word; make up ones mind; be concerned about.;catch up with.; keep an eye on.;concentrate on.等。考点2 特殊固定用法keep.doing sth.;p
13、revent.from doing.;like doing.;need doing; feel like doing; get sth. done; have sth. done;have sb. doing/do sth.;enjoy doing; succeed in doing等。考点3 常用句型so/such.that.It is.(for sb./of sb.) to do sth.There is no doubt/need that.There is no sense in doing sth.Its ( high) time that sb. did/should do sth
14、.It is no good/use doing sth. not only.but also. It is/was the first (second) time that sb. has done/had done sth. It is no wonder that. 特殊句型结构及固定搭配在语法填空中主要考查对其掌握的熟悉程度,所以我们要善于积累,牢记固定搭配和特殊句型,答题时注意固定搭配的介词、名词、动词的形式和特殊句型的形式主语、连接词及相应时态的运用等。代词it在特殊句型中非常活跃,所以考生需要特别注意包含it的常用句型:1.用在动词 like, love, dislike, ha
15、te, appreciate等后作宾语。如:I hate it when people talk with their mouths full.我讨厌人们满嘴食物说话。2.作形式主语或形式宾语用于It is+adj./n.+不定式或动词-ing形式或that从句中。如: It is certain that he will succeed.他一定会成功。用于It seems/appears/happens/occurs to sb.+that 从句中。如: It occurred to me that I should ask the police for help.我突然想起我应该向警方求助
16、。用于It looks as if/as though.中。如:It looks as if were going to miss the plane.似乎我们要误了班机了。用于It is+过去分词+that从句中。如:It is believed that he will be admitted to Beijing University.人们相信他将被北京大学录取。用于think/find/make+it+adj./n.+不定式或动词-ing形式或 that从句中。如:I make it a rule to walk two miles a day.我通常每天步行两英里路。用于 take
17、it for granted that., bring it to ones attention that.,see to it that.等句型中。如:We take it for granted that water is free at restaurants.我们认为在餐馆里水免费饮用是理所当然的事情。3.构成特定句型It is/has been.since.It is almost ten years since he enjoyed himself so much.将近有十年时间他没这么高兴过了。It was (not)/will(not) be.before.It was not
18、 long before he sensed the danger of the position.不久他就感受到此处的危险。It is sb.s turn to do sth.Its my turn to look after the baby.轮到我看孩子了。1.When a new day breaks, the walls have given up their heat and are now cold enough _ (cool) the house during the hot day;_ the same time, they warm up again for the ni
19、ght.【解析】根据语境可知,第一空处应该用动词不定式,构成adj./adv.+enough to do结构,所以第一空填to cool;根据语境可知;第二空填介词at,构成短语at the same time,表示同时。【答案】to cool; at2. Keep_ (hold) your position for a while. It helps develop your strength and flexibility.【解析】根据语境可知,此处作动词keep的宾语,构成固定搭配,keep doing sth.意思是继续做某事因此填动词-ing形式。【答案】holding3.It to
20、ok years of work _(reduce) the industrial pollution and clean the water.【解析】It takes/took (sb.)+.+to do sth.为固定句型,意思是做某事花费(某人)多长时间。所以此处填动词不定式。【答案】to reduce题组一(2020年高考真题)Cloze 1(2020年浙江省高考英语试卷(1月)阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。Something significant is happening to the world population-it is agin
