1、 考试要求

It be…that/who强调句型
0.65
1.强调结构
1.强调句型。
(1)强调句型的基本结构为:It is/was+被强调的部分+that/who+句子其他部分。该句型可对句子的主语、表语、宾语、同位语、状语等进行强调。
(2)强调句型的一般疑问句结构为:Is/Was+it+被强调的部分+that/who+句子其他部分?
He asked what it was that made him so upset.
他询问究竟是什么让他如此难过。
(3)强调句型的特殊疑问句结构为:特殊疑问词+is/was+it+that+句子其他部分?
【易错提醒】强调句型亦可用于宾语从句中,但注意语序要用陈述句语序。
It was not until he took off his sunglasses that I realized him.
直到他摘下墨镜我才认出他。
(4)not...until句型的强调句型结构为:It is/was not until...+that+句子其他部分。
2.强调谓语动词。
用助动词do,does或did来强调谓语动词,用于一般现在时和一般过去时的肯定的陈述句中,do还可以用于祈使句。
2. 倒装句
1.将含有否定意义的副词或连词置于句首引起的部分倒装结构。这类词(组)有:never, seldom, rarely, little, few, at no time, by no means, no longer, hardly/scarcely...when..., no sooner...than..., not only...but also..., not until, nowhere, neither...nor...等。
Never before has she seen anybody who can play tennis as well as Robert.
她以前从没见过打网球和罗伯特一样好的人。
2.only+状语置于句首时,主句要进行部分倒装。
Only after they had discussed the matter for several hours did they reach a decision.
讨论这个问题数小时后他们才做出决定。
3.作状语的介词短语放于句首时引起的句子要全部倒装。有时为了强调将作状语的介词短语放在句首,而将主语放到句末;或者当句子中主语较长时,为了使句子平衡,常把作状语的介词短语置于句首。
Through the window came in the sweet music.
从窗户里飘出美妙的音乐。
4.so/such...that...结构中的so,such连同它所修饰的成分共同位于句首表示强调时,主句要用部分倒装。
So frightened was she that she could not say a word.
她如此害怕以至于一句话也说不出来。
Such great progress did he make that he was praised.
他取得了如此大的进步以至于受到了表扬。
5.表示前面所说的情况也适合于后者时,用倒装结构“so/neither/nor+助动词/系动词/情态动词+主语”(so表示肯定意义,neither/nor表示否定意义)。
6.as引导的让步状语从句要用倒装结构。即as引导的让步状语从句中必须将表语、状语(形容词、副词、分词)或实义动词提前,构成“形容词/副词/名词/动词/分词+as+主语+谓语的其他部分”的形式。
使用as进行倒装时需要注意的是:
(1)句首是单数可数名词时,名词不能带任何冠词。
Pop star as she is, she still needs to improve.
尽管她已是很受欢迎的歌手,但仍需要提高。
(2)句首是实义动词时,其他助动词则放在主语之后。如果实义动词有宾语和状语,则宾语和状语随实义动词一起放在主语之前。
Fail as I did, I would never give up.尽管我失败了,但我不放弃。
3.省略句
1.复合句中的省略。
在用as if, if, though, when, where, while, no matter what, until等引导的从句中,若谓语部分含be动词,而主语又与主句的主语一致时,从句的主语和谓语中的be动词可以一起省略。
All the photographs in this book, unless stated otherwise, date from the 1950s.
这本书里的相片,除非有说明,否则都是二十世纪五十年代的。
2.动词不定式符号to的省略及不定式的省略。
在主动语态中,感官动词或使役动词后接不定式作补足语时,往往将不定式符号to省略;在同一句话或同一情景对话中,当同一动作再次出现在后面的不定式位置上时,通常省略该动作而保留不定式符号to。
3.so/not构成替代省略。
英语中还常常用so/not等来代替省略的肯定内容或否定内容,so/not多跟在I'm afraid/I hope/I think/I guess/I believe等开头的答句中;条件状语从句中有时也有类似的用法,如:if so/if not等。
It sounds like something is wrong with the car's engine. If so, we'd better take it to the garage immediately.
听起来好像汽车引擎出故障了。如果这样的话,我们最好立即把它送到汽修厂。
4. 感叹句
1.what引导的感叹句
what引导的感叹句
示例
What+a/an+(adj.)+单数可数名词+主语+谓语!
What a good heart you have!你的心肠真好!
What+(adj.)+不可数名词/复数名词+主语+谓语!
What interesting stories he's told us!
他给我们讲的故事真有趣!
how引导的感叹句
示例

How+adj.+a/an+单词名词+主语+谓语!
How clever a boy he is! 他是一个多么聪明的男孩啊!
How+主语+谓语!
How time flies! 光阴似箭!
5. there be 句型
There be 句型表示“某时间/空间存在/有……”,there本身没有词义,谓语动词be后面的名词/代词是主语。be可以有不同的时态,可以和情态动词连用。There be结构中的谓语动词be有时可用remain, stand, lie, go, exist, follow, live, come, occur, happen to be, appear to be, seem to be , used to be等替换。
Once upon a time there lived an old fisherman in a village by the sea.
从前在海边的一个村庄里住着一位老渔夫。
There have been many great changes in our country since then.
从那以后,我国发生了许多巨大的变化。
a.There be句型中的谓语动词be在人称和数上应与其后的主语保持一致。
There is a flower in the bottle.
瓶中有一朵花。
There are five books on the desk.
桌上有五本书。
b.若There be句型中主语为并列结构,be的数和人称遵循就近原则。

房子里有一个男孩、一个女孩和两个妇女。
There are ten students and a teacher in the office.
办公室里有十个学生和一个老师。

I expect there to be no argument about this.
我希望在这方面不会有任何争论。

1.(2024·天津·高考真题)Coffee may cause sleep disturbance, especially when _________ in large amounts or after 2 pm.
A.consumed B.being consumed C.consuming D.having consumed
【答案】A
【难度】0.85
【知识点】状语从句中的省略
【详解】考查非谓语动词。句意:咖啡可能会引起睡眠障碍,尤其是大量饮用后或在下午两点以后饮用。此处为状语从句的省略,且consume意为“吃;喝;饮用”,与句子主语 coffee构成逻辑上的动宾关系,省略be动词,故用过去分词形式。故选A。
2.(2018·天津·高考真题)What was it ______ brought you two together? Was it your love of music?
A.as B.who C.that D.which
【答案】C
【难度】0.65

【详解】考查强调句式。句意:是什么让你们走到一起的?是因为你对音乐的热爱吗?。分析句子可知,本句为强调句式It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分。特殊疑问句的强调句型:疑问代词或疑问副词+ is/ was + it + that/ who + 其他部分。故选C项。
3.(2019·天津·高考真题)The professor warned the students that on no account ________ use mobile phones in his class.
A.should they B.they should
C.dare they D.they dare
【答案】A

【详解】考查部分倒装和情态动词。句意:这位教授警告学生们,在他的课堂上,决不应该使用手机。on no account意为“决不”,否定词放在句首,句子使用部分倒装,排除B、D项;这里表示应该,故选A。
4.(2018·天津·高考真题)It was only when the car pulled up in front of our house ___________we saw Lily in the passenger seat.
A.which B.that
C.when D.where
【答案】B

点睛:本题考查强调句,要求有学生掌握好强调句的常用句型以及相关知识的能力。分析句子时首先要看清楚结构,It is / was…开头而后面跟句子时就要看它是不是强调句了。强调句有一个特点:拿掉It was/is…that…后不影响整个句子的完整性,则是强调句。判断完是不是强调句后再根据强调的部分是人还是物来选择连接词that或者是who。
5.(2024·全国·模拟预测)Not until he went abroad to further his study _______ the importance of English.
A.has he found B.he has found
C.did he find D.he had found

—Yes. We ______ be proud of it then.
A.when; do B.that; do C.which; did D.that; did
【答案】D
【难度】0.65
【知识点】强调谓语(do+动词原形)、It be…that/who强调句型、一般过去时表过去的动作和状态
【详解】考查强调句型与助动词对动作的强调。——中国宇航员成功登月是在2003年吗?
——是的。我们当时确实为此感到自豪。第一空为强调句型,强调的是时间in 2003,所以用that引导。第二空是对谓语进行强调,表示对动作强调用助动词do、does或者did+动词原形;此处描述的是过去的事情,所以用did。故选D。

【详解】考查部分倒装。句意:——今年夏天我不能去度假了。——我也不能。根据语境可知,第二句意思是“我也不能去”,“也不”是neither/nor,由第一句中的can’t可知,第二句中也用情态动词can,neither/nor是否定副词,位于句首时引起部分倒装,即将can提前到主语前面,因此空格处是Neither can I。故选A。
9.(24-25高三上·甘肃兰州·开学考试)On no occasion ______ the occasion when we first met at China- Ireland Cultural Festival two years ago.
A.will forget I B.I will forget C.will I forget D.will I forgot
【答案】C
【难度】0.65
【知识点】forget、否定副词位于句首的倒装
【详解】考查部分倒装。句意:在任何情况下,我都不会忘记两年前我们在中爱文化节上第一次见面的那一刻。On no occasion“任何情况都不,在任何场合都不”是一个否定词组,位于句首时,主句需要部分倒装,本题将助动词will放在主语I之前,动词forget“忘记”用原形。故选C。
10.(23-24高三下·广东中山·阶段练习)It was not until he came back home ______ he knew what had happened.

11.(2023·山东·一模)In the beautiful garden an artificial hill (假山) and some tall trees.
A.stand B.stands C.have D.has
【答案】A
【难度】0.85
【知识点】have(举办)、一般现在时、全部倒装、语法一致
【详解】考查时态,主谓一致和倒装。句意:在美丽的花园里矗立着一座人造小山和一些高大的树木。句子是表方位的介词短语位于句首引起的全部倒装句,还原成正常的语序是an artificial hill (假山) and some tall trees_____In the beautiful garden;结合句意表示“矗立”用动词stand,句子描述客观事实,时态用一般现在时,主语an artificial hill (假山) and some tall trees是复数,因此空格处用动词原形,故选A。
12.(2023·天津·模拟预测)It was in this old school ________ the government built in 1968 ________ he received good education.
A.where; when B.which; that C.that; which D.where; which
【答案】B
【难度】0.4
【知识点】It be…that/who强调句型、关系代词which引导限制性定语从句
【详解】考查定语从句和强调句。句意:正是在那座由当地政府1968年建造的学校里,他接受了良好的教育。分析句子可知,________ the government built in 1968为定语从句,先行词this old school在从句中作宾语,第一空用关系代词which/that。第二空构成强调句,用固定句型“it is+被强调部分+that/who+其余部分”,被强调部分非人,应用that。故选B项。
13.(2023·天津·二模)—How is the man injured in the accident?
—The doctor said if________ in a proper way, he was likely to be saved.
A.treated B.treating C.is treated D.to be treated
【答案】A
【难度】0.85
【知识点】状语从句中的省略
【详解】考查状语从句的省略。句意:——那个人在事故中是怎么受伤的?——医生说如果治疗得当,他是有可能得救的。分析句子成分可知,空处应为非谓语动词。if引导的条件状语从句的主语和主句的主语一致,且从句的谓语动词为was,则可以省略从句的主语和be动词,故用done形式作状语。故选A。
14.(22-23高三上·天津·开学考试)When ________to compare the education system of China and Britain, the professor gave no answer.
A.ask B.asking C.asked D.to ask
【答案】C
【难度】0.65
【知识点】ask、状语从句中的省略、过去分词表示被动意义
【详解】考查时间状语从句的省略。句意:当被问及比较中国和英国的教育制度时,教授没有回答。分析句子可知,本句符合时间状语从句的省略情况,即主句主语与从句主语一致,均为the professor,且从句谓语动词含有be动词的时候,从句的主语和be动词可省略,所以此处其实完整从句为When (the professor was) asked to compare the education system of China and Britain,所以填asked,表示“被问到”。故选C项。

A.to be stated B.stated C.stating D.is stated
【答案】B
【难度】0.4
【知识点】一般现在时的被动语态、状语从句中的省略
【详解】考查非谓语动词以及状语从句中的省略。句意:所有的规定都适用于高三学生,除非另有说明。从句意和句子结构可知unless引导的条件状语从句的主语与主句主语“regulations”一致,“regulations”与“state(解释,说明)”之间是被动关系且从句为一般现时,即“unless they are otherwise stated”。当从句主语与主句主语一致,且谓语动词含有be动词时,可以省略从句的主语和be动词。故选B。
