从句与非谓语之间的转换一、当从句的主语与主句的主语一致(定语从句的主语与先行词一致),如果从句中是:1)从句用be动词作谓语be + doing; 省略be;(例10)be + done;省略be;(例4)be + 介词短语;省略be;(例2)be + 形容词 / 副词; be变为being;(例9)be + 名词; be变为being;(例1)2)如果从句中是其他行为动词作谓语是一般现在时或一般过去时就一律用doing的进行时化简;(例3)是完成时态或after引导的一般时态,用having done化简.(例7和11)二、当状语从句的主语与主句的主语不一致时,也可按上面第一条中方法化简复合句。
化简后的短语前加上原从句中的主语即可(既是独立主格结构)。

知识讲解知识点1:不定式〔短语〕与从句的关系1.【考查点】:不定式〔短语〕在句中作主语,其功能相当于一个主语从句,因此二者之间可以转换。
(1).To be able to help you is really an honor.(=That I’m able to help you)(2).He seemed to know the way.(=It seemed that he knew the way.)(3).Bush is said to have decided to attack North Korea.(= It is said that Bush has decided to attack North Korea.)..2.【考查点】:不定式〔短语〕在句中作宾语或宾补,相当于一个宾语从句(1).We still don’t know when and where to build a school.(宾语)(=when and where we should build a school)(2).I advised him to go and see the doctor.(宾补)(=that he should go and see)(3).He thought it a great pity not to have invited her. .(宾语)(=That he hadn’t invited her.).3.【考查点】:不定式〔短语〕在句中作表语.,相当于一个表语从句(1).My suggestion is for them to leave as soon as possible.(=that they should leave)(2).My chief purpose has been for them to get a good understanding.

从句与非谓语动词之间的转换非谓语动词和从句可以相互转换,那么如何将复合句改为简单句呢?首先,需要分清主从复合句,然后取消从句,一般要把引导从句的连词去掉。
例如,将"When he was waiting for the bus。
he saw a dog"改为"Waiting for the bus。
he saw a dog"。
其次,如果从句的谓语动词是主动式,就要把谓语动词改为现在分词;如果从句的谓语动词是被动式,就要把谓语动词改为过去分词,并且要注意时态的变化。
例如,将"After he had finished his homework。
he went home"改为"Having finished his homework。
he went home"。
另外,使用分词短语作状语时,它逻辑上的主语必须与句子的主语一致。
如果主从句的主语不一致,在取消掉从句变为-ing或-ed形式时,要把从句的主语保留,其它部分和以前的改法一样。
例如,将"As it was hot。
we went swimming"改为"It being hot。
we went swimming"。
需要注意的是,在使用分词短语作状语时,它也可以有自己独立的逻辑上的主语,这种结构称为独立主格结构。
在很多情况下,它都表示一种伴随的动作或表示一种原因。
例如:1.If the weather allows。
I will go there.2.After the rain ped。
XXX.3.His XXX。
and he prepared to return to his institute.4.With so many comrades absent。
XXX.From the above examples。
we can see that the present participle (-ing) usually indicates an n that is happening at the same time as the main verb in the sentence。
动词的时态与非谓语动词的关联与宾语从句与同位语从句的异同动词的时态是语法中的重要概念,它用于表达动作或状态的时间。
非谓语动词是指动词的非时态形式,包括动词不定式、动名词和分词。
而宾语从句和同位语从句是由名词从句引导的从句结构,用来充当名词成分。
本文将探讨动词的时态与非谓语动词的关联以及宾语从句与同位语从句的异同之处。
一、动词的时态与非谓语动词的关联:动词的时态表示动作或状态发生的时间,主要包括一般现在时、一般过去时、一般将来时等。
非谓语动词则是动词的非时态形式,可以作为动词的宾语、主语、定语等。
在语法上,动词的时态和非谓语动词之间存在一定的关联。
1. 动词不定式:动词不定式是非谓语动词的一种形式,一般由“to + 动词原形”构成。
它可以表示目的、原因、结果、目标等。
动词不定式与时态之间存在一定的关联,可以通过时态的变化来表达不同的时间概念。
例如:- 一般现在时:She likes to play basketball.(她喜欢打篮球。
)- 一般过去时:He wanted to become a doctor when he was young.(他小时候想成为一名医生。
)- 一般将来时:They are going to visit their grandparents next week.(下周他们打算去看望他们的祖父母。
)2. 动名词:动名词是非谓语动词的一种形式,一般由动词的-ing形式构成。
它可以作为主语、宾语、表语或定语等。
与动词的时态关联,动名词通常没有明确的时态概念,而是通过上下文来确定动作发生的时间。
例如:- 一般现在时:Listening to music helps me relax.(听音乐帮助我放松。
)- 一般过去时:I enjoyed playing football when I was a child.(小时候我喜欢踢足球。
)- 一般将来时:She is considering going abroad for further study.(她正在考虑出国深造。
定语从句和非谓语动词定语从句和非谓语动词定语从句和非谓语动词一直是SAT/ACT语法,甚至是理解阅读文章中长难句的重点,也是困扰很多考生的难点之一。
下面是店铺收集整理的定语从句和非谓语动词的相关内容,希望对您有所帮助!定语从句和非谓语动词解析:熟悉非谓语动词的们应该都知道,非谓语动词包括to do, doing 和done,这三类动词的特别之处就在于它们可以在句子里面充当除谓语以外的任何成分,其中一个非常重要的用法就是位于名词后作为名词的后置定语,比如:The semiarid lands bordering the deserts exist in a delicate ecological balance and are limited in their potential to adjust to increased environmental pressures.以上例句里的非谓语动词的短语“bordering the deserts”就是用作定语来修饰前面的`名词短语“the semiarid lands”。
很多同学很熟悉定语从句,而对非谓语动词的用法总是有种望而却步的感觉。
但是细心的同学肯定会发现,其实在语法家族里,当将非谓语动词用作后置定语的时候,它与定语从句的用法是一样的,两者是名副其实地长相不同,但却有血缘关系的“远房表亲”。
比如,上面的例子我们就可以改写成定语从句:The semiarid lands which border the deserts exist in a delicate ecological balance and are limited in their potential to adjust to increased environmental pressures.再如以下带有非谓语动词短语的句子:Theorist adopting the psychodynamic approach hold that inner conflicts are crucial for understand human behavior, including aggression.我们可以改成定语从句:Theorist who adopt the psychodynamic approach hold that inner conflicts are crucial for understand human behavior, including aggression.又如,以下的两个句子的意思是相同的:1.What audience came to see was the magic made possible by trick photography and manipulation of the cinema.2.What audience came to see was the magic that was made possible by trick photography and manipulation of the cinema.在很多情况下,学生更容易理解定语从句。
非谓语动词与状语从句的转化非谓语动词与状语从句的转化状语从句是同学们在初中就掌握的内容,现将非谓语动词与状语从句之间转换的规律作一归纳,帮助大家更好地掌握非谓语动词。
一、非谓语动词与时间状语从句间的转换。
1 .当主、从句的主语一致,主、从句的谓语动作同时或L乎同时发生时,且从句中谓语动词是主动语态,可用现在分词的一般式转换。
如:When they heard the news,they jumped with joy.Hearing the news,they jumped with joy.当他们听到这则消息时,高兴得跳了起来。
2 .当主、从句的主语一致,从句中的动作发生在主句的动作之前或从句中谓语动词是完成时,可用现在分词的完成式转换。
如:After he(had)returned home,he began to work.Having returned home,he began to work.回到家以后,他开始工作。
3 .当主、从句主语一致时,由after,before,since,as soon as等引导的从句可分别用after/before/since/on加动名词短语转换。
如:Since I saw you last,I have been ill.Since seeing you last,I have been ill.自从我上次见你后,就一直在生病。
As soon as he heard this,he couldn’t help crying.On hearing this,he couldn’t help crying.他一听到这事,不禁哭了起来。
4 .当主、从句主语一致时,以when,while引导的从句,也可用when /while加现在分词短语转换。
如While we were walking along the river, we heard someone shouting.While walking along the river,we heard someone shouting当我们正沿着河走时,我们听到有人喊叫。

如,a sleeping baby, a used car, a frightening experience, a frightened child, etc.A baby who is sleeping.A car which is usedving形式由动词的主动形式派生而来;表示主动的动作或正在进行的动作Ved形式由动词的被动形式派生而来:表示被动的动作或已完成的动作The fallen leavesThe falling leavesThe custom fascinates me.The fascinating custom has been the subject of many books.The baby will sleep until eight.Try not to wake a sleeping baby.Some movies are rated X.Children shouldn’t see X-rated movies. My leg was broken in three places.My broken leg is healing slowly.The sinking ship= the ship that was sinking The sunken ship=the ship that has sunken. Falling leaves=Fallen leaves=现在分词的完成时态:表示分词的动作发生在主句谓语动词动作之前。
