初中英语虚拟语气讲练(附答案)

初中英语虚拟语气讲解及练习

英语中的语气分为陈述语气、祈使语气、虚拟语气三类。

虚拟语气表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。

如果假设的情况可能发生，是真实条件句，这种情况下谓语用陈述语气。如：If time permits, we'll go fishing together.如果时间允许，我们就一起去钓鱼。

如果假设的情况是不存在的或不大可能发生的，则是虚拟条件句。如：If you had come yesterday, you would have met that famous professor.如果你昨天来，你就会见到那位著名的教授了。（隐含的事实是：你昨天没来，也没见到那位著名教授）。

虚拟语气的基本形式和用法在含有虚拟条件句的复合句中，主从句的谓语都要用虚拟语气。

1. 含有条件状语从句的复合句

wish（would rather）+宾语从句

suggest（…）+宾语从句

2. 主语从句 It is + adj./p.p/n.+ that+ S+ (should) +do

表语从句S+is that +s + (should) +do

同位语从句 S+that +s +(should) +do

3. 定语从句 It is (high) time that + S + did

用过去式表现在情况

1. 时态后退型用过去完成式表过去

两种形式用过去将来表将来

2. should+动词原形型

内容详述

I. 含有条件状语从句的复合句(以do为例;S=主语)

时间条件状语从句主句

与现在事实相反的假设 If +S+did…S+would/should/could/might+do…

与过去事实相反的假

设 If +S+had done… S+would/should/could/might+have done…

与将来事实相反的假设did…

If+S should do

were to do

S+would/should/could/might+do…

注意事项：

1．倒装句。如果条件句中含有功能词had，should，were时，可以省去If，把功能词提前，构成倒装句。

2．错综条件句。若条件句和主句动作不存在同一个时间，则谓语形式应根据具体情况而定。

3．If there weren't/had not been +…=without…

4．If it were not for…/ If it hadn't been for…= but for…

5．otherwise+虚拟语气的句子

6．虚拟语气的句子，but+ 陈述事实的句子

II. 虚拟语气用在宾语从句中

sb. did …(希望现在用过去式)

1. wish+that sb. had done…（希望过去用过去完成式）

sb. would/should do（希望将来用过去将来）

2. would rather后的从句要用虚拟语气。

时间从句

虚拟现在 were, did (动词一般过去式)

虚拟过去 had done

虚拟将来 did (动词一般过去式)

例：I would rather I hadn’t said such unkind things to you. （虚拟过去）

I'd rather you came here for the answer tomorrow morning. （虚拟将来）

I’d rather you posted the letter right away. (虚拟现在)

3. suggest+（that）S+should+do…

表示愿望、建议、请求等主观意向的动词之后的宾语从句，谓语用should ＋动词原形，should常常省略。

这类词有：decide，demand，desire，insist，order，propose，suggest，recommend，requested， require等。

注意：

1. suggest 当“建议”讲时，其宾语从句用虚拟语气；当“暗示、表明”时，用陈述语气

2. insist 当坚持“看法或建议”时，宾语从句用虚拟语气；当坚持“某个事实”时，用陈述语气。

判断改错：（错） Your pale face suggests that you（should）be ill.

（对） Your pale face suggests that you are ill.

（错） I insisted that you（should）be wrong.

（对） I insisted that you were wrong.

III. 虚拟语气用在主语从It is demanded / necessary / a pity + tha t…等结构的主语从句，谓语动词用should 加动词原形，should 可省略。

It is 可用的词有三类 that （should）do

suggested, ordered, required, proposed, demanded, requested, insisted等

important, necessary, natural, imperative, strange等

a pity, a shame, no wonder等

IV．虚拟语气用在同位语从句中。

某些表示建议、请求、命令等主观意向的名词后同位语从句需用虚拟语气，其表达形式为(should) ＋动词原形。

这类名词常见的有：advice，suggestion，proposal（提议），order， demand，desire，request，requirement，recommendation（推荐），plan，resolution（决议）， idea 等。

eg. We are all for your proposal that the discussion ( should )be put off．

V．虚拟语气用在表语从句中。

某些表示建议、请求、命令等主观意向的名词作主语时，表语从句需用虚拟语气，其表达形式为(should) ＋动词原形。

这类名词常见的有：advice，suggestion，proposal，order， demand，desire，request，requirement，recommendation以及plan，idea，resolution等。

eg. My suggestion is that the mayor (should)present the prizes.

VI．虚拟语气用在定语从句中

It is（about ／high）time ＋that sb.did sth/should do sth..

eg. Don't you think it's about time we went home？

注：在this is the first time ／second time that．．．句型中，从句中谓语动词用陈述语气完成时态。

eg.Is this the first time that you have visited Hongkong？

VII. 虚拟语气用在让步、方式、目的状语从句中

1．在带有even if/ even though引导的让步状语从句的主从复合句中，主句和从句都用虚拟语气，动词形式与含有非真实条件句的虚拟语气相同。

如: Even if he had been ill, he would have gone to his office. 即使生了病，他俩去办公室。

2．由as if或as though引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或“had十过去分词”。

如: He treated me as if I were a stranger. 他那样对待我，好像我是陌生人似的。She talked about the film as if she had really seen it. 她谈论那部影片，就好像她确实看过一样。

3．虚拟语气用在lest（唯恐、免得），for fear that及in case引导的目的状语从句中。在由lest等引导的目的状语从句中需用虚拟语气，表示“以防，以免”等意思，其谓语动词多由should ＋动词原形构成，should也可省略。

eg. He was punished lest he should make the same mistake again．

VIII．虚拟语气用情感语言中

1．虚拟语气在表示客气、遗憾以及祝愿等场合中，使用虚拟语气。

eg.You shouldn't have been following him so closely；

you should have kept your distance．

2．If only sb./sth. +时态后退型的谓语

eg. If only I had known the result of the examination.

IX.虚拟语气的特殊用法：

1. 省掉if的条件从句结构：

Had you asked me, I would have told you.

(=If you had asked me,…)

2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示，如：

A true friend would not do such a thing.

(=If he were a true friend, he would...)

3.有时条件从句中的动作和结果从句中的动作发生的时间不一致，如：

If he had followed the doctor’s advice, he would be quite all right now.

If I were you, I would have gone home.

初中英语五种基本句型结构

初中---五种基本句型中考对五种基本句型的考查主要集中在以下几方面： 1. 掌握五种基本句型的基本用法。 2. 掌握五种基本句型在用法上的区别。中考考查这部分内容时的题型和大体分值为：单选（1分）写句子（1分）写作（1-2分）阅读理解（1-2分）一、知识精讲五种基本句型是句子最基本的组成部分。掌握了这五种基本句型，在阅读中当我们遇到较复杂的句子时，运用这些基本句型，对句子的分析就会变得容易多了。在写作中，首先要能运用好这些基本句型，才能得到高分。（一）五种基本句型的句子成分： 1. 句子成分的定义：构成句子的各个部分叫做句子成分。句子成分包括主要成分和次要成分；主要成分有主语和谓语；次要成分有表语、宾语、定语、状语、补足语等。 2. 主语（subject）：主语是一个句子所叙述的主体，一般位于句首。主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。【例句】 We often speak English in class. 我们在课上经常说英语。 Smoking does harm to the health. 吸烟对健康有害。 The rich should help the poor. 富有的人应该帮助贫困的人。 3. 谓语（verb）：谓语可用来说明主语所做的动作或具有的特征和状态。动词常在句中作谓语，一般放在主语之后。分及物动词和不及物动词两种。【例句】 He practices running every morning. 他每天早晨练习跑步。 I have caught a bad cold. 我得了重感冒。 We like helping the people in trouble 我们喜欢帮助那些处于困境中的人。

考研英语语法大全———自己总结

考研英语十二大基础语法体系对于任何英语句子，要分析其结构，这样才能找到英语语言的规律。每种语言都有它的难点，汉语的难点在于汉语不是拼读语言，汉字很难写，而且有四种声调。其实，许多接触过多种外语的人都认为，英语的语法比法语、德语、俄语、日语等都简单，是最容易学的。著名语言学家乔姆斯基说过，语法是内生的、也就是随着语言的诞生而诞生的。因此，学习语法和学习语言是相辅相成的。一、英语动词的时态（一）英汉两种语言在时态表达方式上的差异：英语的词类与汉语的不同。汉语词类形态稳定，比如“书”这个字，“一本书”、“三本书”都一样，没有词形变化。英语就不同了，book, books仅从词形上就能知道是单数还是复数。动词是英语中变化最多、最复杂的词类。有人说，学好英语就是学好动词，此言甚是。同一个动作或状态分别在不同时间发生或存在，表达这个动作或状态的动词就要用不同的形式，这就是时态。（二）英语动词的形式：英语的时态是通过动词的变化来体现的。因此，了解动词的形式及其变化规律非常重要。英语的实义动词有以下五种形式： (1)动词原形：动词原形在句子中形式不变。主要用于主语为非第三人称单数的一般现在时，情态动词之后，或根据语法规定必须用动词原形的其他情况。 (2) 一般现在时第三人称单数形式（简称现单三）：主要用于主语为第三人称单数的一般现在时。 (3) 过去式：主要用于一般过去时。 (4) 现在分词：主要用于进行时态，或语法规定的其他情况。 (5) 过去分词：主要用于完成时态，或语法规定的其他情况。动词一般现在时第三人称单数（现单三）的构成，见下表：

即某些字母组合的不规则动词有一定的规律。如：weep→wept, sleep→slept, sweep→swept 以上每个时间段中分别有四种状态：一般、进行、完成和完成进行。因此我们便有了四四一十六个时态。态（一般、进行、完成、完成进行）。比如在“They are doing their exercises.”这个句子中，动词由原形do 变成are doing 的形态，说明这个事情是发生在现在、并处于正在进行的状态当中，所以叫现在进行时；在“They have done their exercises.”这句中，动词由原形do 变成have done的形态，说明这个事情是发生在现在、并处于完成的状态，所以叫现在完成时；在“They always do their exercises.”中，动词用原形do 的形态，说明这个事情是发生在现在、并且是一般情况下永远如此，所以叫一般现在时。在这三句话中，动词do 虽然用了不同的形态，其意义没有变化，而是事情发生的时间和状态变了。其余类推。（三）时态详解 16个时态中，常用的有12个：一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、将来进行时、现在完成时、过去完成时、将来完成时、现在完成进行时和过去完成进行时。其他时态很少单独使用。下面把各种时态的构成和用法做一个全面的介绍。

(英语)初中英语虚拟语气练习题及解析

（英语）初中英语虚拟语气练习题及解析一、初中英语虚拟语气 1． If I ＿＿you . I＿＿study harder. A．am , will B．was, would C．were, would D．were, will 【答案】C 【解析】试题分析：句意：如果我是你，我会更努力学习。这个句子要用虚拟语气，表示与事实相反。所以用过去式were, would,故选C。考点：考查虚拟语气。 2．I don’t understand how you got a ticket. I always you a careful driver. A．think; are B．am thinking; are C．thought; were D．think; were 【答案】C 【解析】【详解】句意：我不明白你是怎么得到罚单的。我一直以为你是一个谨慎的司机。考查动词时态辨析题。本句是虚拟语气，与过去事实相反，需用一般过去时；根据句意结构，可知选C。 3． If I ____Alice, I _____them the truth. A. was , would tell B. were ,would tell C. am, will tell D．is , will tell 【答案】B 【解析】试题分析：本题的含义是如果我是你，我将告诉他们真相，本题if引导的是一个虚拟的条件句，在虚拟句中，be用were，主句通常用过去的一种，will应该用would，故本题选B。考点：if引导的虚拟条件句。点评：在英文中条件句有两种，一种是真实的条件句，if后遇到将来时用一般现在时，一种是虚拟的条件句，if后用过去时，be用were，在英文的实际使用中应该注意它们的区别。 4．If I you, I the army. A．am, would join B．were, would join C．am, will join D．were, will join 【答案】B 【解析】试题分析：句意:如果我是你,我会参军.结合语境可知本句是对客观状况的虚拟,故用过去时态,主句用过去将来时态.选B.

初中英语基本句型及练习

基本句型（Basic Sentence Patterns）英语的句子在结构上可以归纳为五个基本句型。 A．第一基本句型 S + V 解说各例句的黑体字是主语，斜体字是谓语动词。主语通常是一个，但是也可以如例5有两个，甚至两个以上都可以成立。谓语动词也是一个较为普通，但是也可以如例4，5有两上，甚至更多也能成立。本句型的Vi．属于完全不及物动词.谓语动词的前面可加情态动词或助词.如多个谓语动词并列可用and,but 等并列连词将它们连接起来,谓语动词在人称和数上须与主语保持一致. 注：“There + be（Vi．） + S…”也是属于第一基本句型。例如：例：There is an alarm clock on her desk.例：There stands a tower on the hill. B．第二基本句型 S +V + P 解说各例句的黑体字是主语，斜体字是谓语动词(连系动词)，字底加线的是主语补语。什么是主语补语？请观察： ①My name is （我的名字是）

②These roses look （这些玫瑰花看起来）上面两例虽各有可作主语的名词“name”和“roses”，也有谓语动词“is”和“look”，但是句意不清楚，无法表达完整的句意，所以不是句子。现在若在例1之后加“Tom”，例2之后加“very beautiful”，那么句意就完整地表达出来了。像这样，一个词（通常是n．pron．或adj．）在谓语部分里补充说明主语者就叫做主语补语。主语补语通常是一个，但是依表达的需要也可以有两个（如例6），或更多。谓语动词需要取主语补语才能把句意表达完整者叫做不完全不及物动词。注：下列常见“It…”句式也是属于第二基本句型。 1．It + be + a/n .+ to v…（不定式）例：It is nice to see you again. 例：It is your duty to take care of your mother. 2．It + be +adj +for +o + to V… 例：It is easy for us to learn to speak English.

人教版初中英语九年级教案之 unit4 + 虚拟语气

Unit 4 What would you do? 在本单元内我们要完成以下学习任务： 1．学习表示与现在事实相反的虚拟语气的结构。 2．学习谈论一些假设的、虚拟的情况。 3．学习使用虚拟语气提出建议。一、重难点提示 1．What would you do if you had a lot of money? 如果你有很多钱你将做什么？这是一个与现在事实相反的假设，用的是虚拟语气。虚拟语气用来表示说话人的愿望、假设、猜测或建议，而不表示客观存在的事实。虚拟语气通过谓语动词的特殊形式来表示。在本单元中出现的是虚拟语气中的一种：表示与现在事实相反的一种假设，与if引导的条件状语从句一起使用。结构：条件状语从句中的谓语动词用过去式（动词be多用were），主句中的动词用would＋动词原形。 e.g. —What would you do if you had a million dollars? 假如你有一百万美元你将干什么？ —If I had a million dollars, I’d buy a plane and travel around the world. 我将买一架飞机并周游世界。 e.g. If I were you, I’d wear a shirt and tie. 如果我是你，我会穿衬衣打领带。 I’d=I would 2．What if everybody else is wearing jeans and T-shirts? 如果别人都穿牛仔裤、T恤衫怎么办呢？ what if的用法：（1）如果……怎么办？ e.g. What if I don’t know anyone? 如果我不认识任何人怎么办？（2）即使……又有什么关系？ e.g. What if he goes angry? 即使他生气又有什么关系？ 3．—What are you like? 你是个什么样的人？ —I think I’m creative and outgoing. 我想我具备创造力并且善于交际。 ※注意以下几个句子所询问的不同内容：（1）What are you like?(like是介词)询问的是性格（personality）。（2）What do you like?

初中英语语法大全：英语五个基本句型

初中英语语法大全：英语五个基本句型1简单句、并列句、复合句根据语法形式，即句子的结构，英语的句子可分为简单句、并列句和复合句。 1简单句句型：主语+谓语只包含一个主谓结构，而句子的各个结构都只由单词或短语表示。简单句有五种基本句型，详见第十七章。 They are playing baseball in the garden. 他们正在公园里打棒球。 Her brother and sister both are teachers. 她的哥哥和姐姐都是老师。 2并列句句型：简单句+并列连词+简单句（常见的并列连词有and，but，or）并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。 My friend was at home，and we talked for along time. 我的朋友在家，我们谈了好长时间。 Her father is a doctor and her mother is a teacher.

她父亲是个医生，她母亲是个老师。I liked the story very much but Li Ming wasn't interested in it.我非常喜欢这个故事，可是李明却对它不感兴趣。 Hurry up，or you'll be late. 快点，否则你就会迟到的。 3复合句句型：主句+连词+从句；或连词+从句+主句（包含一个主句、一个或一个以上的从句，或只包含一个从句，但有两个或两个以上的主句的句子叫复合句。）句子的成分组成句子的各个部分叫做句子的成分。句子成分包括：主语、谓语、表语、宾语（直接宾语、间接宾语）、宾语补足语、定语和状语。主语和谓语是句子主体部分（在英文中一般的句子必须有主语和谓语）。表语、宾语和宾语补足语是谓语里的组成部分。其他成分如定语和状语是句子的次要部分。下面我们分别讲述一下句子的各个成分： 1主语主语是谓语讲述的对象，表示所说的“是什么”或“是谁”。一般由名词、代词、不定式或相当于名词的词或短语来充当。它在句首。 We study in No.1 Middle School.（讲述“谁”～）我们在一中学习。 The classroom is very clean. （讲述“什么”很干净）这间教室很干净。 Three were absent.（数词作主语）

考研英语完形填空--红花绿色词原则完整版本

两大原则，力保四分第一：红花绿叶原则每次出现，每次都选的单词为红花词。每次出现，每次都不选的词为绿叶词。红花词（按排名）：however,also,yet,while,because（一定背着，很重要）绿叶词：是见到后不选的词：排名第一的是：since,而且谁跟since谁倒霉，since家族都不选，同义词：eversince,nowthat一次都没选过。还有绿叶词：what，它是著名的说和关系词，不选。What不能跟在名词后，就不能引导定语从句和同谓语从句。而定语和同谓语是考试的大热门。所以它是个绿叶词。还有两拨绿叶词，一个是涉及到虚拟语气的词。而在考研的历年考题中却出现得很少，是因为考研完型填空选材因素，完型填空都选于比较严肃的话题，而虚拟语气不能适应严肃的场景，故出现得很少。排第一的是：If only；要想了解这个词，还有only if ，only if就是if；但if only却不是only，only if既不是红花也不是绿叶。 If only用英文来解释的话，相当于I wish，相当于要是，只要，要是什么什么多好呀。 If only的用法，它的后面跟从句，从句的时态，如果与过去的情况相反，从句用过去完成时。如果与现在情况相反，从句用一般过去时。如果从句与将来的情况相反，从句用过去将来时，用would/could+动词原形。 If only或者I wish后面跟句子，它后面的句子都是过去时态，这也是是否选此词的依据。如果不是过去时，直接排除！例 44 its economy continues to recover, 44.[A] Even though [B] Now that [C] If only [D] Provided that 所以不选C A variety of activities should be organized 35 participants can remain active as long as they want and then go on to 36 else without f eeling guilty and without letting the other participants 37 . 35.

初三英语虚拟语气讲解及练习题

浅谈初中英语虚拟语气的用法一．语气的概念英语动词不仅有时态、语态等的变化，而且还有语气的变化。语气和时态、语态一样都是英语的语法现象。从形式上看，语气是动词的一种变化形式。从意义上讲，语气是表示说话人对某一行为或某一事情的看法和态度。根据说话人的意图，语气可分3种： ⑴直陈语气（又叫陈述语气）——用来陈述事实（或提问题）等。可以用于陈述句，也可以用于疑问句或感叹句。 ⑵祈使语气——用来提出请求或命令等。主要用于祈使句。 ⑶虚拟语气——见下面。语气和时态是截然不同的概念，但语气要通过动词的时态形式表示出来。二．虚拟语气㈠概念通常是表示说话人所说的话不是一种事实，而是一种纯粹的假设、虚拟、主观愿望或建议等。可以用于陈述句，也可以用于疑问句等。㈡动词形式虚拟语气的动词形式大多数情况是用动词（相应）的过去时（相对直陈语气而言）。动词be若用过去式时可以一律用were。㈢应用 ⑴在含有条件状语从句的复合句中的应用。表示纯粹的假设，或可能性很小的情况。主从句的谓语动词主要形式如下：例：1）If I were you, I’d wear a shirt and tie. 2）What would you do if you had a million dollars ? 3）If you had come a few minutes earlier, you would have met him. 4）If he hadn’t been strict with himself, he wouldn’t have made such progress. ⑵在wish等宾语从句中的应用。表示纯粹的主观愿望，不可能实现的，或实现的可能性极小的情况。宾语从句谓语动词根据具体情况常可用一般过去时，过去将来时或过去完成时等。例如： 1）I wish that I could help him now. 我现在要是能帮上他该多好啊！或我多么希望现在能帮上他！（言下之意：我现在帮不上他，没能力帮助他） 2）I wish I could come here tomorrow. 明天我要是能来这儿就好了！（言下之意：我明天根本不可能来这儿，或我明天能来这儿的可能性很小） 3）We wish he hadn’t gone. 他要是没有走该多好啊！ ⑶用在suggest等的宾语从句中，表是纯粹的建议。句型为：suggest(ed) that … (should) + 动词原形…（should可省略） 1）He suggests that we (should) visit the museum. 2) We suggested that he _____ here every day. A. come B. comes C. came D. can come E. could come 虚拟语气的几种特殊用法 1.省掉if的条件从句结构： Had you asked me, I would have told you. (=If you had asked me,…) 2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示，如： A true friend would not do such a thing. (=If he were a true friend, he...) (=If there were no water,…) (=If you hadn’t helped me,…)

(完整word版)初中英语语法专项虚拟语气

初中英语语法专项练习十四——虚拟语气 1. When a pencil is partly in a glass of water, it looks as if it _______. A.breaks B.has broken C.were broken D.had been broken 解析：答案为C。本题考查的是as if 引导的让步状语从句中的语气问题，as if引导的状语从句如果与事实一致，不用虚拟语气，如果与事实相反，应用虚拟语气。题中“当铅笔的一部分浸在水中，铅笔看上去好像断了”。而实际上铅笔并未断，与事实相反，前半部分陈述是一般现在时，因而本句是对一般现在时的虚拟，用were broken。 2. I didn't see your sister at the meeting. If she ___________, she would have met my brother. A.has come B.did come C.came D.had come 解析：答案为D。本题考查的是if条件句中的虚拟语气。题意是：我在会议上没看到你姐姐，故你姐姐没来。因此如果“她来了”与事实相反，前面一句交代了虚拟语气的时态是一般过去时的虚拟，所以if从句中用had+过去分词。 3. —If he ___________, he ________that food. —Luckily he was sent to the hospital immediately. A.was warned; would not take B.had been warned; would not have taken C.would be warned; had not taken D.would have been warned; had not taken 解析：答案为B。本题考查的是条件状语从句与主句表示与事实相反时虚拟语气的用法。根据下一句语境可知，他事先并没有得到警告，表示过去时间的虚拟语气，故选B。 4. If there were no subjunctive, English ______ much easier. A.will be B.would have been C.could have been D.would be 解析：观察题干，可知全句表达的是与现在事实相反的虚拟语气。故答案为D。 5. The guard at the gate insisted that everybody ______ the rules. A.obeys B.obey C.will obey D.would obey 解析：根据insist后的宾语从句谓语要用(should) do形式规律，可定正确答案是B。 6. I wish I _____ you yesterday. A.seen B.did see C.had seen D.were to see 解析：此题表与过去事实相反的原望，答案应为C。 7. ——If he _____ , he _____ that food. ——Luckily he was sent to the hospital immediately. A.was warned;would not take B.had been warned;would not have taken C.wuld be warned;had not taken D.would have been warned;had not taken 解析：从对话看，是表达与过去事实相反的虚拟语气，故答案为B。 8. Without electricity human life _____ quite different today. A.is B.will be C.would have been D.would be 解析：without引出一个含蓄条件句，主句表述的是与现在事实相反的虚拟语气，故答案为D。 9. When a pencil is partly in a glass of water, it look as if it _____. A.breaks B.has broken C.were broken D.had been broken
