英语语法精讲(非谓语动词)

顾名思义,非谓语动词即是没有在英语语句中作为谓语使用的动词及动词短语,包括不定式,现在分词,过去分词及动名词四种类型。

?不定式

不定式的形式有一般式to do,一般式的被动形式to be done;进行式 to be doing;完成式to have done以及完成式的被动形式to have been done.

A.不定式的功能:

在英语语句中作主语,例句:

It is necessary for us to set a goal in life and get ourselves motivated by it all the time.

To accomplish such a heavy load of work in the given time is rather beyond his ability,indeed.

To be or not to be is a question.

作宾语,例句:

We did not expect to be greeted with such warmth at our arrival.

He decided to face the punishment rather than attempt to escape.

作表语,例句:

Our duty is to fulfill our personal value and make contributions to our nation’s grow in the meantime.

His job with the company is to plan for campaigns to promote their products in market.

特别提示:如果主语是不定代词或者疑问代词时,作表语的不定式符号to可以省略,例句: Faced with such a severely doubtful outcome,all we can do is (to) keep mute. What can been done with the present matter is make a quick move to stop the spread of the disease.

作定语,例句:

The invited guest to deliver a speech at the opening ceremony has arrived ahead of schedule.

The letter to be posted lies on the manager’s desk.

特别提示:作定语的不定式在主动式to和被动式to be done之间的选用原则是看句中是否有不定式动词的逻辑主语,如果有,使用to do 作定语,否则就要使用to be done。请注意以上两个例句不定式主动式和被动式的选用。

作状语,通常为目的状语,例句:

We’ll have to start out some ten minutes to arrive on schedule in case of a traffic jam.

He actually did not mean to speak out those words to hurt you anyway.

作同位语解释前边它所修饰的名词,例句:

Our duty,to keep the passengers safe,is sometimes rather challenging while traveling across those African countries.

作主语补足语和宾语补足语,例句,

We feel rather embarrassed if we are caught to be cheating in exams.

It is a bitter thing when teachers and parents or on frequent occasions, life itself make us devote ourselves into our studies.

特别提示:使役动词make,let,have,及感官动词see,watch,feel look at,observe,hear 等,的宾语后的宾语补足语的不定式符号to要强行省掉。

?现在分词,基本形式doing, 被动式 being done

作定语,例句:

Kids going to school far away from their home may enjoy some sort of better educational resources,but suffer greater losses in their close relation to their parents meanwhile.

The man winning the first prize of the huge some of cash will be kept anonymous. (注意,现在分词作定语时,和被修饰的对象之间一定是逻辑的主谓关系。一般单独的一个现在分词作定语是前置定语,现在分词短语定语一般后置。)

作谓语动词的伴随状语,例句:

Friends are those who usually make their presence when they are needed,coming to your help or offering you comforts.

Failing again the driving license test,he decided to give in.

作主语补足语和宾语补足语,例句:

Anyone caught committing any crime in the tiny country receives severe punishment, most times capital punishment indeed.

(caught committing any crime 是个过去分词短语作定语,而其中的committing any crime 作主补。)

Shortage of income gets many people working longer hours these days.

?过去分词,唯一的形式:done

作状语,例句:

Beaten in the final game,our team once again narrowly missed the championship. They were arrested on the scene,found performing commercial cheats.

作定语,例句:

The newly built villa at the foot of the mountain disturbs the natural surroundings,which used to be source of income as a tourist attraction.

The employees blamed for the loss are concerned about the risk of be fired. 特别提示:过去分词作定语要分清及物动词和不及物动词来理解并掌握。及物动词的过去分

词作定语,和被修饰对象之间一定是逻辑的动宾关系;不及物动词的过去分词作定语,和被修饰之间是逻辑的主谓关系,表动作完成。例句:

Crops grown here in the field are expecting a good harvest in autumn.

Crops grown in autumn are demanding harvest in time,before the rain season destroys them.

作主语补足语和宾语补足语,例句:

The Covid-19 disease, if left untreated,causes high rate of loss of life.

The police will not leave the victims stuck in the broken car.

补充独立自主结构:

(中学期间不要求掌握这个语法知识,但还是有可能在阅读中出现,能够学通这一语法难点更好。)

先看例句:

Water heated,we see vapor come out of it.

Weather permitting,the picnicking camp will be held as scheduled.

通常情况下,无论是现在分词还是过去分词做状语,分词动词和句子都有逻辑关系。如果是逻辑的主谓关系,使用现在分词作状语;如果是逻辑的动宾关系,则使用过去分词作状语。而上边的两个例句却不是这种语境表述。分词动词heat(加热)和句子主语we之间没有逻辑关系,或者没有讲话人需要突出阐明的逻辑关系。heat和讲话人要讲述的对象water,有着逻辑关系,那么water以主格的形式置于heat之前,由于它们之间是逻辑的动宾关系,所以使用过去分词heated,便构成了water heated这样的过去分词的独立主格结构,作状语。

第二个例句里,主语the picnicking camp和permit之间没有逻辑关系,而讲话人需要阐述weather的一些信息,且它和permit 之间有逻辑的主谓关系,permitting紧随weather 以主格形式之后,构成weather permitting这样的现在分词独立主格结构。

由于普通名词的主格和宾格形式是一样的,容易忽略它需要以主格形式使用。如果是代词,就一定要小心,如下:

They found trapped in the traffic jam,the police are fighting to clear a way for them to move ahead.

She shocked by the sudden news,some disturbing voice are sounded within herself.

英语语法归纳之非谓语动词(过去分词)

英语语法归纳之非谓语动词(动名词) 敬告: 以下内容,不参加高考等有语法题(语法单选、语法填空、短文改错等)考试的应用类学员无须深究,知道该语法结构的存在,及其充当的句子成分和功能即可,应多花时间练习听说读写,否则就背离了语言学习真正目的。应试类学员有时间可以比较分析,基本搞懂。 过去分词长什么样?规则的情况下与动词过去式相同,当然有不规则的情况;过去分词可以充当定语、状语、补语、定语,不可能充当主语、宾语; 过去分词不像现在分词有多种体现时态和语态的形式,只有一种形式done表示。 1、过去分词可以充当主谓宾补句型中的宾语补语;它与宾语是被动关系,或者说它与宾语是动宾关系。 (1) We found the fish eaten by our cat. (2) I can’t make myself understood because of my poor English. 2、过去分词可以充当定语;充当定语当然是修饰主语、宾语等名性的结构;表达过去分词的动作是被动的或完成,或即被动又完成的。 (1) The party had last night (which was had last night) was very cheerful. (2) USA is a developed country (a country which has been developed). (3) A great number of students questioned (who had been questioned) said they were forced to practice the piano. 3、过分词可以充当状语,它与主句主语是被动关系,或者说它与主句的主语是动宾关系; 过去分词一般只强调被动动作而不强调时间,多用于条件和原因状语;(1) Taken in time, the medicine will turn out to be very effective. If the medicine is taken in time, it will turn out to be very effective. (2) Offered an important role in a new movie, Andy has a chance to become famous.

初中英语语法知识精讲精练动词

初中英语语法知识精讲精练:动词 (一) 知识概要 动词在语言中是必不可少的一部分。它的语法现象也较多,但在初中范围主要有以下几方面问题。①时态:初中范围主要有一般现在时,一般过去时,现在完成时,过去完成时,将来时与过去将来时六种时态。②语态:主动语态与被动语态。③助动词和情态动词。④非谓语动词,也就是不定式,动名词及现在分词的用法。时态主要掌握以下几种时态的应用要点和习惯用法。 1. 一般现在时:主要有以下三方面,①用来表示状态,特征或不受时间限制的客观存在和真理。如:Matter exists in three states物质有三态。又如:The earth moves around the sun. ②表示习惯性和经常发生的动作,如:I often go to bed at 9∶30. ③在时间、条件等状语从句中表示将来要发生的动作,如:As soon as I get there I'll telephone you. 2. 一般过去时:①主要用于表达过去时间内发生的动作或存在的状态,如:I was ill last week. ②过去经常发生的动作或习惯性动作,如:I used to get up at six. 3. 一般将来时:用于表示将要发生的动作,其构成方式①用will (shall)+动词原形来表达将来在某一时间内要发生,或经常、将要发生的动作或状态,如:School will begin on Sepember 1st. ②用be going to+动词原形,用来表示不久将要发生或打算去作的动作。如:I'm going to swim this afternoon. ③ be+现在分词,也就是用某些动词的现在进行时表示将来,如:I'm coming。这些动词只限于:go, come, leave, start, move, sail, arrive, reach, get to等动词。④在状语从句中用一般现在时表示将来。 4.现在进行时:用于表示现在正在进行的动作,如:What are you doing now?要注意的是表示状态,情感的某些词没有现在进行时,这些动词有:like, have (有),love, know, understand, remember, forget, see, hear, smell, taste, feel, wish hope, expect… 5. 过去将来时:用来表达从过去某时间点上看将要发生的动作,如: He told me he would come to my party. 6. 现在完成时与过去完成时:现在完成时的两个用处是: ①用来表达在过去开始的动作持续到现在,如:I've studied English for two years. ②用来表达过去发生的事但它影响到现在,如:I haven't had my breakfast. so I'm hungry now. 现在完成时与过去完成时的区别在于动作的截止时间,现在完成时所表达的动作截止于现在,而过去完成时所表达的动作截止于过去。如:I haven't seen my old teacher for a long time.我好久未见到我过去的老师了。是指到目前截止。如果加上一句话,则将变为过去完成时,如:Yesterday I saw my old teacher. I hadn't seen him for a long time. 因为我好久未见他这一情况截止于昨天。还要注意的一个问题是截止性动词可以有完成时,但不能与表示一段时间的状语连用,如:When I got to school, the class had begun? 如果一定要讲开始几分钟了则要换用表示状态,或延续性动词,如:When I got to school, the class had been on for five minutes.语态:英语中只有主动语态与被动语态之分。主动语态,句子中的主语是动作的执行者,如:I broke the window. 而被动语态句子中的主语是主动语态句子中的宾语,如:The window was broken by me. 被动语态主要用于,
