当主句的主语和从句的主语一致时且谓语动词为be

英语非谓语动词用法详解(1)一、单项选择非谓语动词1．After a decade or so, out of choices, he returned to where he’d begun, ashamed at having so little to show for his wanderings.A．being run B．runningC．to run D．having run【答案】D【解析】【详解】考查现在分词。

句意：大约十年后，在没有选择的情况下，他回到了他开始的地方，为自己的拼搏没有什么收获而感到羞愧。

run out of “用光，耗尽” 与主语he在逻辑上是主动关系，且表示的动作明显发生在return之前，所以用现在分词的完成时having run of。

故D 选项正确。

【点睛】非谓语动词是考试考查的重点，要掌握它的用法。

首先，要弄清楚填空处要填的是非谓语。

其次，要知道非谓语动词的三种形式：现在分词表示主动进行、过去分词表示被动完成、动词不定式表示目的和将要。

再次，要知道非谓语动作与谓语动作是同时发生还是先后发生，还是将要发生。

其中分词做状语的考查尤为重要。

分析句子可知，本句的主语为he,谓语为returned, run out of “用光，耗尽”为非谓语与主语he在逻辑上是主动关系，且表示的动作明显发生在return的之前，所以用现在分词的完成时having run of。

故D选项正确。

2．Don't turn a deaf ear to the advice which will make a ________to your future.A．mess B．differenceC．fuss D．remark【答案】B【解析】不要对能够对你未来产生影响的建议掩耳不闻。

make a different to对什么有影响，是固定短语，所以选B。

3．Shortly after suffering from a massive earthquake and ________ to ruins, the city took on a new look.A．reducing B．reduced C．being reduced D．having reduced 【答案】C【解析】【详解】考查动名词的被动语态。

专题15 特殊句式——高效演练一．单句语法填空1.____________ seems to be intense competition among students to enter a key university.【解析】：句意：学生们进入重点大学的竞争似乎很激烈。

考查there be句型。

there be句型中的be有时可用seem to be等替换。

【答案】：There2．After the major earthquake he was surprised at ____________ hungry people were for mental and emotional help.【解析】：句意：大地震之后，他惊讶于人们那么迫切地需要精神和情绪上的帮助。

本题介词at后接宾语从句，且宾语从句为感叹句，how后接形容词hungry；短语be hungry for意为“对......渴望/渴求”。

【答案】：how3.Not until recently they encourage the development of tourist-related activities in the rural areas.【答案】：did【解析】根据时间状语"recently"及动词encourage可知本句应用一般过去时。

"Not until+状语"位于句首时,句子采用部分倒装。

故填助动词did。

4.If (accept)for the job, you’ll be informed soon.【答案】accepted【解析】句意:如果你被录用做这份工作的话,你会很快收到通知的。

当状语从句的主语和主句的主语一致且从句谓语部分有be动词时,状语从句的主语和be动词可以省略。

该题中的条件状语从句补充完整为If you are accepted for the job。

非谓语动词选择题练习和答案一、单项选择非谓语动词1．（天津）I didn't mean ___________anything but the ice cream looked so good that I couldn’t help_______ it.A．to eat；to try B．eating；tryingC．eating；to try D．to eat； trying【答案】D【解析】考查短语固定搭配。

句意：我不打算吃任何东西，但冰淇淋看起来如此的好以至于我忍不住的要试一试。

固定短语短语mean to do（打算做），couldn’t help doing忍不住做。

故选D。

点睛：本题考查动词短语固定搭配。

同学在平时学习中要多把握动词不同搭配的不同含义，本题需要区分“mean to do打算做”与“mean doing意味着做”和“can’t help to do sth.不能帮助做”与“couldn’t help doing忍不住做”之间的含义。

2．________ terrible, the medicine was thrown away by the child.A．Tasted B．TastingC．To taste D．Being tasted【答案】B【解析】【详解】考查非谓语动词。

句意：这种药尝起来非常难吃，被这个孩子扔掉了。

主语是medicine，taste与主语是主动关系，而且taste是系动词无被动，因此用现在分词，故选B。

3．______ to nuclear radiation, even for a short time, may influence genes in human bodies. A．Having exposed B．Being exposedC．To expose D．Exposed【答案】B【解析】【详解】考查动名词。

句意：暴露于核辐射中甚至很短时间都会影响人体的基因。

语法进阶技巧定语从句的省略和引导词定语从句是英语语法中的一个重要部分，用来修饰一个名词或代词，并且在句中起到进一步说明的作用。

在定语从句中，有时可以省略一些词语或引导词，从而使句子更加简洁明了。

本文将介绍定语从句省略和引导词的进阶技巧。

定语从句的省略可以分为两种情况：省略引导词和省略关系代词。

首先，我们来看一下省略引导词的情况。

1. 当先行词是不定代词(all, any, some, none, something, anything等)时，定语从句引导词可以省略。

例句1: Is there anything (that) I can do for you？例句2: I have something (that) I want to show you.2. 当先行词是指示代词(this, that, these, those)或疑问代词(what, which, who, whom, whose, how, when, where, why)时，定语从句引导词可以省略。

例句1: The book (that) you recommended to me is very interesting.例句2: I don't know the reason (why) he left.3. 当先行词是不定代词或指示代词后面紧跟的名词是唯一的，且其功能与定语从句中的先行词在意义上是一致的时候，定语从句引导词可以省略。

例句1: I need a pen (that is) blue.例句2: She told me a story (that was) unbelievable.接下来，我们来看一下省略关系代词的情况。

1. 当关系代词在从句中作宾语时，且从句的谓语动词是及物动词时，可以将关系代词省略。

例句1: I have seen the man (whom/that) you are talking about.例句2: This is the book (which/that) I bought yesterday.2. 当关系代词在从句中作主语时，且从句的谓语动词是不及物动词时，可以将关系代词省略。

状语从句一．分类：种类连接词注意区别：时间状语when/whenever/while/as/before/after/instantly/until/till/by the time/as soon as/hardly…when/no sooner…than/the moment/the minute/immediately有一些表示时间的名词短语也可用来引导时间状语从句：the minute, the moment, every time, the first time例：The moment he reached the country, he started hissearch. 他一到达这个国家，就开始他的探寻工作。

有一些表示时间的副词也可用来引导时间状语从句：directly例：Directly the master came in, everyone was quiet.校长一进来，大家就安静下来as和when、while：as, when 引导短暂性动作的动词。

当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或while。

从句表示"随时间推移"连词能用as，不用when 或while。

till/until和not…till/until：until可用于句首，而till通常不用于句首。

地点状语where//wherever where，表示某一个；wherever，表示任何一个。

原因状语Because/as/since/now that/forbecause和since、for、as、now that：because语势最强，用来说明人所不知的原因，回答why提出的问题。

当原因是显而易见的或已为人们所知，就用as或since。

由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。

但如果不是说明直接原因，而是多种情况加以推断，就只能用for。

常考易错点：1）句法错误：如定语从句关系词使用错误，名词性从句引导词错用。

2）行文逻辑的错误：如连词使用不当。

1.（2020·全国I卷）First I cut the tomatoes into pieces but put them aside.【答案】but改为and【解析】考查连词。

前后句是递进关系，故将but改为and。

2.（2020·全国I卷）After that I poured oil into a pan and turned on the stove, I waited patiently unless the oil was hot.【答案】unless改为until/till【解析】考查连词。

句意：我耐心地等着，直到油热起来。

此处表示“直到”，故将unless 改为until/till。

3.（2020·全国II卷）Then I can spare some time to learn it again, such that we can practice together every day.【答案】such改为so【解析】考查连词。

so that表示以至于，故改such为so。

4.（2020·全国II卷）Thank you for your letter, what really made me happy.【答案】what改为which【解析】考查定语从句。

此处为引导词引导非限制性定语从句，修饰前面整个句子，且在从句中作主语，故把what改为which。

5.（2020·全国III卷）In order to make sure all of us are in good health, and she makes specific plans for us.【答案】去掉and【解析】考查简单句。

这是一个简单句，前面in order to...作目状语，不用连词and，所以去掉and。

从句的省略规则从句是在句子中充当一个整体，起到修饰、表达具体含义的作用。

在使用从句的时候，有时候可以采用省略规则，即省略一些不必要或重复的成分，使句子更加简洁明了。

本文将介绍从句的省略规则，帮助读者更好地理解和运用这一语法现象。

一、主语从句的省略在主语从句中，如果主句的主语与从句的主语一致，且从句的谓语动词是be动词（am，is，are，was，were），可以将从句的主语省略。

例句1：That he is talented is well known.（从句的主语he省略）例句2：Whether she can come or not is still unknown.（从句的主语she省略）二、宾语从句的省略在宾语从句中，如果从句的主语和主句的宾语一致，且从句的谓语动词是be动词，可以将从句的主语和be动词省略。

例句1：I don't know if he's ready.（从句的主语he和be动词省略）例句2：She wonders whether it's true or not.（从句的主语it和be动词省略）三、宾语补足语从句的省略在宾语补足语从句中，如果从句的主语和主句的宾语补足语一致，且从句的谓语动词是be动词，可以将从句的主语和be动词省略。

例句1：They elected him chairman, which was a wise choice.（从句的主语which和be动词省略）例句2：We made her the team captain, which turned out to be a mistake.（从句的主语which和be动词省略）四、定语从句的省略在定语从句中，当从句的主语和关系代词或关系副词引导的介词宾语一致时，可以将从句的主语和关系代词或关系副词省略。

例句1：The book I borrowed from the library is very interesting.（从句的主语I省略）例句2：The girl I saw at the party is my best friend.（从句的主语I省略）五、状语从句的省略在状语从句中，当从句的主语和主句的主语一致，且从句的谓语动词是be动词，可以将从句的主语和be动词省略。

高三英语非谓语动词解题技巧讲解及练习题（含答案）含解析一、单项选择非谓语动词1．Bats are surprisingly long lived creatures, some ______ a life span of around 20 years. A．having B．had C．have D．to have【答案】A【解析】考查非谓语动词。

句意：蝙蝠是一种寿命很长的动物，有的寿命约为20 年。

根据与前面句子是逗号连接，没有连词，故判断后一句使用独立主格结构，空格处用非谓语动词，逻辑主语some 与have 是主谓关系，故要用v-ing 形式，故选A。

2．When _________ for his views about his teaching job, Philip said he found it veryinteresting and rewarding.A．asking B．askedC．having asked D．to be asked【答案】B【解析】试题分析：句意:当马克被问做教师这个职业时的看法。

他说他发现这个工作是非常有趣和值得的。

这里when 引导的省略句，完整的是when he was asked his view about his job as a teacher ，这里当从句中的主语与主句的主语一致，并且从句的谓语动词有be 时，这时从句的主语与be 同时省略，故选B。

考点：考查省略的用法。

点评：本题难度适中。

为了使话说得简明扼要，英语句子中某个单词、短语甚至从句或主句都可以省去。

这种省去句子某些成分而保持句子意思不变的现象，称为省略。

它是高中阶段的重要的语法项目，需要考生仔细分析句子结构，来确定省略的内容。

这里考生容易误选A。

即学即练:He is rather difficult to make friends with, but his friendship ， ______ is more true than any other.A.once gainedC.after gaining解析：A。

状语从句主谓成分的省略状语从句主谓成分的省略是英语语言在使用过程中出现的一种较普遍的语法现象，它能使语言言简意赅。

Though understanding no Chinese, the American girl was able to communicate with the other students in her class.When asking the teacher, he was very polite.Until finished, the problem was a continuous worry to me.He’ll go to the seaside for his holiday if (it is) possible.一、状语从句主谓成分的省略，须遵循下面原则：（一）当从句的主语与主句的主语一致时，从句可以省略主语，从句的谓语动词采用其V-ing 结构。

例如：Although working very hard, he failed in the final exam. (Although he worked very hard,…)After t aking the medicine, she felt much better. (After she took the medicine,…)If going there by air, we’ll have to pay twice the fare. (If we go there by air,…)（二）当从句的主语和主句的主语一致时，若从句的谓语动词是系动词be或包含be的某种形式，此时从句的主语和be动词通常可以一同省略。

常见于以下几种形式:1、连词+形容词Whenever (she is) free, she often goes shopping.她有空就去逛商店。

Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。

有一些表示时间的副词也可用来引导时间状语从句：directly例：Directly the master came in, everyone was quiet.校长一进来，大家就安静下来as和when、while：as, when 引导短暂性动作的动词。

当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as或while。

从句表示"随时间推移"连词能用as，不用when 或while。

till/until和not…till/until：Until可用于句首，而till通常不用于句首。

地点状语where//wherever where，表示某一个；wherever，表示任何一个。

原因状语Because/as/since/now that/forbecause和since、for、as、now that：because语势最强，用来说明人所不知的原因，回答why提出的问题。

当原因是显而易见的或已为人们所知，就用as或since。

由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。

但如果不是说明直接原因，而是多种情况加以推断，就只能用for。

当主句的主语和从句的主语一致时且谓语动词为be，常省略从句的主语和be动词.省略的条件: (1)从句中被省略的主语必须与主句的主语一致,或者是it；(2)谓语动词必须含有be；(3)从句必须与主语和be动词一起省去，不可只省略主语而保留整个谓语，也不可只保留主语而省略谓语。

本题考查时间状语从句的省略用法。

当主句和从句的主语一致，且从句中含有be 动词时，可以省略从句中的主语和be 动词。

4._ he came in, I was reading a book.A.WhileB.WhenC.AsD.All of the above答案：D。

宾语从句的省略和替代技巧的示例在英语语法中，宾语从句是一个重要的句子结构，它在句子中充当宾语的角色。

然而，在某些情况下，为了简化句子或使语言更加流畅，我们可以采用省略或替代技巧来处理宾语从句。

本文将介绍一些常用的省略和替代技巧，以及相关的示例。

一、省略宾语从句的情况1.省略连词“that"在宾语从句中，当主句的谓语动词是感官动词（see, hear, feel等），使役动词（make, let等）或使役性动词（want, wish, order等）时，宾语从句中的连词"that"常常可以省略。

例如：- I saw (that) he was crying.（我看到他在哭。

）- She made (that) the children go to bed early.（她让孩子们早点上床睡觉。

）- He doesn't want (that) his parents worry about him.（他不想让父母为他担心。

）2.省略谓语动词当宾语从句与主句主语一致，且宾语从句的谓语动词是“be”时，可以将宾语从句的谓语动词省略。

- She believes he is a good person.（她相信他是个好人。

）- I know it's raining outside.（我知道外面正在下雨。

）3.省略主语和谓语当宾语从句的主语与主句主语一致，且宾语从句的谓语动词是“be”时，可以将宾语从句的主语和谓语动词省略。

例如：- Mary suggested (that) I go to the party.（玛丽建议我去参加派对。

）- Tom insisted (that) we be on time.（汤姆坚持我们要准时。

）二、替代宾语从句的技巧1.使用代词“i t"在某些情况下，可以使用代词“it”来替代宾语从句。

例如：- I find it hard to believe.（我觉得很难相信。

故选A。

2．Be careful when you deal with this chemical, as it will explode when ______ to sunlight. A．exposed B．to expose C．exposing D．being exposed【答案】A【解析】试题分析：考查非谓语动词。

考点：考查非谓语动词3．Several years ago they found in England a tomb of a man ____ from around 2,300 B．C．A．dated B．dating C．dates D．to date【答案】B【解析】【详解】考查非谓语动词。

句意：几年前，他们在英格兰发现了一个可追溯至公元前2300年左右的男子坟墓。

date from表示“追溯到(某一时期)，始于(某一时期)”，a tomb of a man（男子的坟墓）与date from之间为主动关系，应使用现在分词短语作后置定语，若用句子表示二者之间的关系，可以说成A tomb of a man dates from around 2,300 B．C．故选B。

4．Once be falls asleep, I have great difficulty _______ him up.A．wake B．wakenC．to wake D．waking【答案】D【解析】一旦他睡着了，我叫醒他就有很大的困难。

定语从句的省略定语从句是英语中常用的修饰名词的从句形式，用来进一步描述或限定名词的性质、特征等。

通常，定语从句由一个引导词引导，并且在从句中有一个动词，一个主语等。

然而，在一些情况下，我们可以省略定语从句中的部分内容，从而简化句子的结构，使语言更加简洁。

本文将介绍定语从句的省略规则和注意事项。

一、定语从句的省略规则1. 省略引导词和be动词在定语从句中，如果从句中的主语和主句中的主语一致，并且从句中的谓语动词是be动词，那么我们可以省略引导词和be动词。

例如：The car that is parked outside is mine.The car parked outside is mine.2. 省略关系代词who/whom/which当定语从句的关系代词在从句中作宾语时，可以省略。

例如：The girl who(m) I saw yesterday is my neighbor.The girl I saw yesterday is my neighbor.3. 省略关系代词whose关系代词whose表示所有关系，当其后修饰的名词为物时，可以省略。

例如：The book whose cover is torn belongs to me.The book with the torn cover belongs to me.4. 省略关系代词where/when当定语从句中的关系代词是where或when时，可以省略。

例如：This is the school where I studied for four years.This is the school I studied for four years.二、定语从句的省略注意事项1. 定语从句的省略是为了简化句子结构，使其更简洁明了。

但在使用时需要注意不影响句子的准确性和清晰度。

2. 省略定语从句的同时，也要确保句子的语义不会产生歧义。
