英语非谓语动词用法详解(1)
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。

语法进阶技巧定语从句的省略和引导词
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。
高中英语语法-状语从句-归纳总结
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。

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。

so that表示以至于，故改such为so。

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。

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。

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。

状语从句主谓成分的省略

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。

- 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。

定语从句的省略
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。

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。
