谓语动词与非谓语动词的区别
谓语动词与非谓语动词的区别
首先你要明白在一个英语的单句中只有一个谓语，那么你就要学会怎样划分英语句子中的结构。
先说下什么是单句，单句就是只有一个完整句子结构（句号才是整个句子结束的标志）的句子，没有连词和引导词（像and，what，where，这些的词都没有）。具体的单句结构（五个）就不用我说吧。
eg：
①I love my mother.就是一个单句。
②English is my best subject which i like.这就是一个复合句（which引导的限制性定语从句），在主语中，english是主语，is是系动词，my best subject 是表语。在从句中（引导词后边的是从句），which作宾语指代subject（subject 是从句的先行词），I作主语，like在这里是行为动词（vt.）作谓语。
给你一个划分简单句结构的例子：
eg：I like playing basketball.
这个句子中，I是主语，like是谓语，playing basketball是动名词做宾语，在宾语中playing是非谓语动词，因为我刚刚说过了，一个单句中只有一个谓语，所以like做了谓语，playing就一定是非谓语动词了。
现在和你说下最简单的分辨谓语和非谓语的方法：划分句子的结构。
每个句子首先找到主语，然后是谓语，谓语一般都会和主语靠近（有特殊的情况），那么除去谓语之外的其他动词，都是非谓语动词了。
谓语动词：有以下几种分类
①行为动词：行为动词又可分为及物（vt.）与不及物（vi.）
那么vi.和vt.的区别可以通过造句的方式来确定。
及物动词：可直接接宾语。(如果不接宾语，那么句意会不完整）
不及物动词：不可以直接接宾语，需借用介词。
eg：
I go to school by bus.（go不及物动词，但是和home连接时为go home）He drinks water.（drink是及物动词，中文翻译为他喝水，如果没有宾语water，就成了他喝，那他喝什么呢？句意就不完整了。）
②系动词：be动词（is，am，are，were，was）表主语状态，感官动词（hear，look，listen，tast，sound，appear，seem等），持续性动词（keep，stay，lie，remind等），变化动词（become，go，get，turn等）...
③情态动词：could，should，can，must，may等。
④助动词：do，does，did，done.
非谓语动词：一般有三种形式：
①to do（动词不定式）
表目的，将来，另外如果要表示被动时，一般形式是to be done，特殊的是在adj.后边的不定式不能用被动语态，表进行时，一般是to be doing的形式。另外，有一种最简单的it做形式主语的句式你要知道的，It‘s adj. for sb. to do sth.（做某事对于某人来说怎么样） ...还有很多这种句式，你们老师会讲到的。eg：
He seems to have bad cold.（一般式）
The homework must to be done. （被动）
I pretend to be doing homework.（进行）
It‘s easy for me to do this.（It句式）
②dong（V.-ing 动名词形式）
表进行，主动
eg：His father died，leaving him lots of money.（这个是一个单句，died 是谓语，leaving非谓语。）
③done（V.-ed分词型式）
表被动
eg：I should get my homework done quickly.我要使我的作业尽快被完成。（should get谓语，done非谓语）
非谓语动词之todo和ing的区别
非谓语动词之to do和ing的区别 一，作主语时的区别 不定式指较具体的行为 Ing表示抽象或者泛指的动作（但在实际应用常已经可以互换） 注意：两者都可以用it作形式主语，但结构不同 1）ing词it is + no using/no good/useless/ a waste of time + doing sth There is no + ing =it is impossible to do sth Eg.it’s no use waiting here. There is no telling why he did so.(there is no knowing/there is no persuading=it is impossible to persuade …) 2)to do 不定式 It is +adj(n)+(for sb)/(of sb) + to do sth
Eg. It is very difficult to drive in the mountains. It is a shame to say like that . 二，作表语时的区别 不定式强调一次具体动作 Ing强调抽象行为 三，作宾语 不定式agree decline 拒绝refuse offer promise choose decide determine attempt intend manage fail ask hope want tend expect desire wish seek plan prepare pretend learn mean dare arrange demand happen intend Ing 词admit stand appreciate avoid finish complete consider delay deny suggest enjoy escape forgive keep mind miss practise risk advise allow permit forbid 或者介词短语的宾语
英语中if引导的条件状语从句用动词原形还是非谓语动词
英语中if引导的条件状语从句用动词原形 还是非谓语动词 请看下面的句子，空格处应填动词原形还是非谓语动词： If they don't understand it the first time, _________ over it again until they do. A. going B. to go C. gone D. go 【分析】此题正确答案选D，其余几项均有可能被误选。空格前if 引导的是一个条件状语从句，而在空格处无论是填A、B或C，它都是一个非谓语动词短语，而不是一个句子，这样一来，整个句子没有主句，从而导致结构不完整。若选D，则go over it again until they do 则是一个句子(祈使句)，在此用作主语。又如： (1) If he likes to eat it, _________ him some more. A. give B. giving C. given D. to give (2) If anyone calls, _________ them I'm not at home.
A. tell B. telling C. told D. to tell (3) When your mother comes back, _________ her to come to school at once. A. ask B. asking C. asked D. to ask (4) While the baby is sleeping, _________ your work as soon as possible. A. finish B. finishing C. finished D. to finish 答案均选A，空格前分别为if, when, while 引导的状语从句，空格处填动词原形，构成祈使句，用作句子主语。
谓语与非谓语用法区别与练习
谓语与非谓语 使用谓语的情况：句中没有谓语，或者虽然已有谓语动词，但需填的词与已存在谓语主语一致，且中间有并列或转折连词时，需填的词则是谓语动词。时态考虑要瞻前顾后。在确定需要使用谓语动词时候，还需要注意谓语动词的时态，语态，主谓一致以及语气。 使用非谓语的情况：句子已有谓语，又不做并列谓语，该动词仍然需要表示动作，此时应该使用动词的非谓语形式。确定需要使用非谓语时首先要确定该非谓语在句子做何种成分， 非谓语做主语时候只能不定式或者ving形式， 非谓语做定语时：常用在名词或者代词后，其中不定式做定语有将来的意味，过去分词作定语表示该非谓语动词与前面被修饰的名词或者代词为动宾关系，并且此非谓语动词已经完成了。现在分词作定语表示该分词与前面被修饰的名词或者代词为主动关系，现在分词作定语表示主动和进行。 非谓语做宾语时，需要实记哪些动词后只能接不定式做宾语，哪些动词后只能接ving做宾语，哪些动词后2者都可接，但是意义不一样。 非谓语做状语时，不定式表示目的，可放在句子前面，也可放在句子后面，不需要与句子隔开。过去分词作状语表示该分词与句子主语为动宾关系，现在分词作状语时。表示该分词与句子主语为主动关系 1.The first card ____________(design) by J.C.Horsley as a commercial endeavor. designed 2.Smaller cars are just one of the directions that the car industry is taking.

非谓语动词和从句的转换
非谓语动词和从句的转换---- 一.不定式（短语）与从句的关系 1.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.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. (=that they can get a good understanding) 4.不定式（短语）在句中作定语.，相当于一个定语从句 (1).The question will be discussed at the conference shortly to open in Beijing. (=that is shortly to open in Beijing) (2).All dead, I was the only one to grow up. (=that grew up) 5.不定式（短语）在句中作目的．结果状语.，相当于一个目的．结果状语从句 (１).He came to the area in order/so as to study the folk music there.(=in order/so that) (2).The lady was so excited as not to say a word.(=so excited that she couldn’t…)
非谓语动词知识点总结
非谓语动词就是不能作句子谓语而具有其他语法功能的动词。 主语/表语： 不定式和ing分词均能作主语，二者有何区别？ 1.表示某一具体的动作时，多用不定式；表示比较抽象的一般行为倾向的，多用动名词。 2.动名词作主语时通常位于句首；不定式作主语时常置于句末，用it作形式主语放在句首。 1) Smoking is prohibited(禁止)here. 2) It is not very good for you to smoke so much. Seeing is believing. To see is to believe. 若主语和表语都是非谓语动词, 应保持形式上的一致。
宾语： 1. 有些动词后只跟不定式作宾语，如： …… manage, promise, pretend, plan, offer, agree, ask, dare, choose, fail, help(帮助)，want(想要) , refuse等。 决心学会想希望，拒绝设法愿假装。 主动答应选计划，同意请求帮一帮。 2. 有些动词后只跟动名词作宾语，如： ……practise, appreciate, dislike, excuse, forgive, keep, resist, risk, deny, advise, fancy, complete, forbid, permit, allow, stand, refer to, give up, lead to, take to, set about, get down to, object to, succeed in, have difficulty in... 考虑建议盼原谅，承认推迟没得想。 避免错过继续练，否认完成就欣赏。 禁止想象才冒险，不禁介意准逃亡。 3.有些动词如begin, start; love, like, hate, prefer后既可以跟不定式又可以跟ing分词作宾语，意义上无多大区别(但ing分词一般表示经常性的行为；不定式表示具体的行为)。 4.有些动词后既可以跟不定式，又可以跟动名词作宾语，但意义上有明显差别。go on (stop/remember/regret)to do/doing can’t help to do / doing try to do/ doing mean to do（打算）/ doing（意味）be used to do / doing ( get used to doing)(used to do) 5.动词need, require, want作“需要”，deserve作“应受，应得”，主动表被动 定语： 不定式、ing 分词和过去分词都可以作定语，主要区别在于它们的时态意义和语态意义。 分词作定语与动词不定式作定语的区别是：现在分词表示主动、进行之意；过去分词表示被动与完成；而不定式表示在谓语动词表示的动作之后即将发生的动作。 不定式用来修饰序数词、最高级或no, all, any等限定词的中心词，表主动关系。 E.g.: The car to be bought is for his sister. / He was the best man to do the job. The houses being built are for the teachers. Developing countries/ developed countries 补语： 1.能接带to的不定式作宾语补足语和主语补足语的动词有：ask, advise, tell, force, get, allow, want, wish, like, hate, prefer, intend,expect, encourage, persuade, permit, request,order, warn, cause等。 Think, consider, believe, suppose, feel等后常用“to be....”作补语。 E.g.: You are not allowed to smoke here. People considered him to be a great leader. 2.使役动词，感官动词接不带to 的不定式作宾语补足语。常见的使役动词有make, let, have等；感官动词有see, hear, watch, observe, notice, feel以及look at, listen to等。 ◆“吾看三室两厅一感觉”---5看（look at, see, watch, notice, observe）3使（make,

谓语动词和非谓语动词及各种句型的判断
谓语动词和非谓语动词及各种句型的判断 一．意义 谓语动词和非谓语动词在高中英语教和学中具有重要意义，主要表现在写作，语法填空和阅读长难句判断中。 例如：典型例子：1.There are many people stand at the gate. Standing 的误用 2.After luckily _______(succeed) in the national college entrance examination, I realized my dream again. 3.He has two children, both of ________ are doctors. 4. I heard a passenger behind me shouting to the driver, but he refused ____46___(stop) until we reached the next stop. Still, the boy kept ____47___(ride). 5. There were many people waiting at the bus stop, ___42____ some of them looked very anxious and ___43__(disappoint) 6. Maybe you leave a habit __67__ is driving your family crazy. 英语句子的标志：首字母大写，和结尾用句号。T here is a purse on the ground. P rofessor Mayer, recognized by many as a leading expert in the study of changes to people's EQs, recently announced the results of a study on school students. M iss Mary teaches us English. （teaches 动词作谓语） M r.Victor came to our classroom to have a talk with us last week. a，在一个句子中，若只有一个动词，则此动词一定为谓语，若有两个及两个以上动词，就会出现两种情况：1. 两动词都是谓语动词形式，此时两个谓语动词之间必有连词，或并列连词，或从属连词；2. 两动词中必有非谓语，此时两动词之间没有连词。 例如： The novel written by him is very popular. The novel which was written by him is very popular. There is a purse that is lying on the ground. There is a purse lying on the ground. Our coming made him happy. 因此，判断一个句子中谓语与非谓语，带连词与不带连词的方法是：先找句子中的动词，根据连词判断所找到的动词是谓语还是非谓语；或者根据所找的动词的谓语非谓语动词形式判断需要或不需要用连词. 总之，一般句子只要有两个及以上谓语动词形式，必然有连词。反之亦然，只要有连词连接两个动词，必然有谓语动词。 理解这一点对于理解下列句子很有帮助： He has two children, both of __whom__ are doctors. =He has two children, and both of __them__ are doctors. =He has two children, both of __them_ doctors. Our coming made him happy. (简单句。句中两个动词，come和make，谓语动词为make，没有连词连接make和come，所以come用非谓语动词形式) =We had come and that made him happy.（make和come都用了谓语动词形式，有连词and，并列句）

英语中非谓语动词的用法
非谓语动词主要包括不定式、动名词和现在分词。为了区分这三种不同的非谓语动词的用法和含义，我们将分别从三种非谓语动词在句子中做主语、宾语、宾语补足语、定语、状语、表语以及一些特殊结构句型等角度来区分其用法和细微含义。 1．不定式和动名词作主语的区别 （1）动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。Smoking is prohibited(禁止)here．这里禁止抽烟。(抽象) It is not very good for you to smoke so much．你抽这么多烟对你身体很不好。(具体) （2）动名词作主语时，通常用以表示一件已知的事或经验。 不定式短语通常用来表示一件未完成的事或目的。 Climbing mountains is interesting．爬山很有趣。(经验) Driving a car during the rush hour is tiring．在高峰时刻开车令人厌烦。(经验) （3）不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。 It took me only five minutes to finish the job. 2．不定式、动名词和分词作表语的区别 （1）不定式作表语 1)不定式作表语一般表示具体动作，特别是表示将来的动作。 To do two things at a time is to do neither．--次做两件事等于未做。 What I would suggest is to start work at once.我的建议是立刻开始干。 （2）如果主语是不定式（表示条件），表语也是不定式（表示结果）。 To see is to believe.百闻不如一见。 To work means to earn a living．工作就是为了生活。 （3）如果主语是以aim，duty，hope，idea，happiness，job，plan，problem，purpose，thing，wish等为中心的名词，或以what引导的名词性从句，不定式作表语是对主语起补充说明作用。 His wish is to buy a luxurious car in the near future．他的希望是在不远的将来买一辆豪华轿车。 The function of Louis Sullivan's architecture was to provide large uninterrupted floor areas and to allow ample light into the interior. The most important thing is to negotiate with them about the future of the plant． （2）动名词作表语：动名词作表语，表示抽象的一般性的行为。 Our work is serving the people．我们的工作是为人民服务。 His hobby is collecting stamps．他的爱好是集邮。
