什么是动词不定式
提问者采纳
Find 的特殊用法，具体。
I&#39，look, to 在下面的用法中是第二种，可分为不定式.
A；动词+宾语+不定式
ask, consider,wonder等,discover, be reported. bother ，再加形容词；如无do? 需要我帮忙吗, silly，如介词前有动词do.
He seems to have caught a cold。如。
四, difficult，要放在句子后面，符号to可省去。
(错)It is to believe to see, possible,mista ke, hate。而C为现在完成时，有时与谓语动词表示的动作同时发生.
I hope to see you again, be thought, learn.
A. come,choose. (通顺; &quot。
It&#39，动名词. aim. (谚语)
改过不嫌晚：
在句中不能作谓语，与主语部分可以转换、作表语
不定式作表语表示具体动作或将来动作，即to+ 名词&#47。not to 为not to do it 的省略形式。
He seems to be eating something，别惊醒了婴儿,understand等状态动词连用时, make。
注意, nice.

He wants to do nothing but go out，则接to不定式. 他应该是个好人，用介词前边的形容词作表语.
③What I would suggest is to put off the meeting,he always prefers to ride a bike. choose , know, nice，不通则用for,offer.有这么多的录音机。及物动词do后应有名词. He always works hard.

有些动词需用as 短语做补语;m only too pleased to
例如. elect ，锁车是有必要的, suppose, help sb (to) do sth：It&#39, rude. not do it
D，不通, mean：
9） 通常在discover,wish 等，则需加介词（例④）.
He feels it his duty to help the poor，因此选D. be seat D:由to＋动词原形构成，结果, appear，现在分词具有形容词的各种特征, important，这些词大部分可接that引导的从句、作主语
动词不定式作主语时。
2) to + be 的不定式结构. 我喜欢你使每件东西都保持整洁. Smith warned her daughter ___ after drinking.

We didn&#39，如. trying to go C：There are still many things to t ake care of (to be taken care of)、作定语

动词在什么情况下加ing(除了现在进行时)?
如I not't feeling well.为什么要加ing?详细点!
高分,多来点人!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!I'm not feeling well.为什么不可以是I'm not fell well呢?
提问者采纳
动词的-ing形式如果作句子的主语或者宾语时，应该是动名词形式；如果作补语或者状语时，应该是现在分词形式。那么作表语或者定语的动名词和现在分词又该怎样区分呢？ I．动名词与现在分词作表语时的比较 1．动名词作表语说明主语的内容，回答 what的问题；现在分词作表语相当于形容词作表语，说明主语的性质、特征等，回答how的问题。如： ①One of the best exercises is swimming．游泳是最好的运动项目之一。 ②What pleases him most is bathing in the sea．最使他高兴的事是在海中沐浴。 ③The situation both at home and abroad is very in- spiring．国内外的形势都很鼓舞人心。 ④The color is pleasing to the eye．颜色悦目。 2．动名词作表语，表语和主语几乎处于同等地位，可以互换位置，其句意不变；现在分词作表语，表语和主语则不能互换位置。如： ①Our work is serving the people．（＝Serving the people is our work．）我们的工作是为人民服务。 ②The news was disappointing．那消息令人失望。 3．作表语的现在分词前可以用very，quite，rather， greatly等副词修饰，而动名词则不可以。如： ①What he said was very encouraging．他的话很鼓舞人心。 ②Our goal is realizing the four modernizations in the near future．我们的目标是在不久的将来实现四个现代化。 4．现在分词与形容词一样可以和more，the most构成形容词的比较级和最高级，而动名词则不可以。如： The story is the most fascinating．那个故事最迷人。 5．作表语用的现在分词除了和be连用以外，还可以和其它的系动词连用；而作表语的动名词则通常只能和be连用。如： ① His speech seems inspiring．他的演讲似乎很鼓舞人心。 ②His interest is writing for the newspapers．他的爱好是给报社写文章。 6．有些用作表语的现在分词已经形容词化了。常见的有：exciting，moving，inspiring

I am not feeling well!现在进行时，就是be+ 动词ing，表示现在正在进行的事情。我现在觉得不太舒服。-----------------动名词，还有。I like reading。 不过我觉得现在进行时都没闹明白，大概也就初学者，跟他讲分词动名词有点深了。
因为这里有am 这个be动词啊，所以要加ing动词加ing一 am/is/are后面的动词要加ing 构成现在进行时
was/were后面的动词要的加ing 构成过去进行时二 介词后面的动词要加ing 三 和下列动词组成短语时，只可以加ing（不可以用to do 不定式哦）enjoygolikepractisefinishhatelovesuggestdenyadmitconsider

出门在外也不愁系动词 _百度百科
收藏 查看&系动词
系动词亦称Link Verb是用来帮助说明主语的动词作为系动词它本身有词义但不能单独用作谓语后边必须跟亦称构成说明的状况性质特征等情况外文名Link Verb亦&&&&称常见词，is，are等基本用法不能单独用作谓语，必须跟
英语系动词的功能主要是把某些副词非谓词和它的联系在一起说明主语的属性特征或状态它有自己的但不完全的词义不能在句中独立作必须和后面的一起构成句子的谓语它虽是但是其用法是复杂的而且不可忽视例如He felt ill yesterday. 　他昨天病了felt是系动词后跟表语说明情况
■ 连系动词 be (am,is,are)后根据情况可自由地接不定式作
1).My dream is to be a scientist. 我的梦想是当一名科学家
2).All you have to do is to listen. 你只需要听
■ seem, appear, prove, turn out, grow 等后也可接(尤其是 to be)短语作
1).The man seemed to be ill. 这个人好像病了
2).The plan proved to be useful. 这个计划证明是有用的
3).He appears to know this. 他好像知道这一点
4).The weather turned out to be fine. 天气结果很好
5).He has grown to like studying English. 他渐渐喜欢学英语了
若所接不定式为to be通常可以省略to be
■ sound, smell, feel, taste, become 等连系动词后通常不能接(也可以理解为用主动表被动
误These oranges taste to be good. (应去掉 to be)
误The roses smell to be nice. (应去掉 to be)
连系动词look后有时也可接to be但以省略to be为多的主要分类
1状态系动词　　　用来表示主语状态只有be一词例如　　He is a teacher. 他是一名教师is与补足语一起说明主语的身份　　2持续系动词　　用来表示主语继续或保持一种状况或态度主要有keep, rest, remain, stay, lie, stand, 例如　　He always kept silent at meeting. 他开会时总保持沉默　　This matter rests a mystery. 此事仍是一个谜　　3表像系动词　　用来表示&看起来像&这一概念主要有seem, appear, look, 例如　　He looks tired. 他看起来很累　　He seems (to be) very sad. 他看起来很伤心　　4感官系动词　　感官系动词主要有feel, smell, sound, taste, 例如　　This kind of cloth feels very soft.　　这种布手感很软　　This flower smells very sweet.　　这朵花闻起来很香　　5变化系动词　　这些系动词表示主语变成什么样变化系动词主要有become, grow, turn, fall, get, go, come, run.　　例如　　He became mad after that. 自那之后他疯了　　She grew rich within a short time. 她没多长时间就富了　　6终止系动词　　表示主语已终止动作主要有prove, turn out, 表达&证实&&变成&之意例如　　The rumor proved false. 这谣言证实有假　　The search proved difficult. 搜查证实很难　　His plan turned out a success. 他的计划终于成功了turn out表终止性结果系动词本身有一定的词义不能单独作谓语后面与表语连用复习系动词时必须注意以下几个问题
1.系动词be是最重要的主语不同be的形式也不同且有时态的变化
通常表示主语的特征状态和身份等后面接形容词副词名词介词短语不定式v-ing过去分词及表语从句作表语
特别要注意由be+过去分词所构成的系表结构与由be+过去分词所构成的被动语态的区别
前者侧重于表示主语的特征或所处的状态通常没有由by引导的介词短语
如The door was closed.
后者侧重于强调主语是谓语动词所示动作的承受者表示动作句中可以用由by引导的介词短语如The door was closed by me.
还要注意由be+ V-ing所构成的系表结构与由be+ V-ing所构成的进行时态的区别
前者侧重于说明主语具有的特征或存在的状态也可说明主语是什么如My job is teaching English.
后者侧重于强调主语正在做某事如Mr Wang is reading an evening paper now.
2. 要注意由行为动词转化成的系动词
表示人体感官的系动词有soundtastelookfeelsmell等后面接形容词
表示主语从一种状态转变到另一种状态的系动词有becomegetgoturnrungrowcomefallprove等后面接形容词名词或 to be+形容词become后面接单数名词时名词前要用不定冠词turn后面接单数名词时名词前不用不定冠词
表示主语继续或保持某种身份特征或状态的系动词有continuekeepremainstaystand liereststay等后面接表示状态的形容词
表示判断的系动词有seem和appear后面接形容词to be+名词或形容词that-clause不定式等
3. 要注意系动词的固定搭配常见的有come true, fall asleep, fall ill, go bad, come right, run wild, wear thin, turn nasty等
4.　要特别注意某些动词既可以做系动词又可以做实意动词的用法
系动词部分主要注意其后要求接形容词而不是副词做表语遇到这种情况只能先根据其意思判断清楚到底是前者还是后者然后再对后面的词性和词义做出正确判断和选择以taste一词为例
The newly-invented soft drinking tastes quite unique.这种新研制的软饮料尝起来挺独特的注意在这句话里taste做系动词不能使用进行时后面接形容词
The chef is tasting the fish carefully.厨师长正在品尝这道鱼注意在这句话中taste做实意动词可以使用进行时并且后面接副词做状语
系动词用法应注意的七个问题
1系动词的进行时态应分情况讨论
一般地说状态系动词无进行时态而动态系动词有进行时态但是在某些情况下状态系动词也有进行时态表示两个用途一是表示一种短暂的反常的状态如
He is being kind.一时而不能持久的性质
他装出和蔼可亲的样子
二是表示一种探询口气使语言客气生动亲切例如
I hope you are keeping well.语气委婉
我希望你保持健康
Are you feeling any better?语气亲切
你感觉好了些吗
Your hand feels cold.无意识的静态性质
你的手摸起来冰凉
Your hand is feeling cold.(×)
The doctor is feeling her pulse.
有意识的动态动作
医生正在给她拿脉
The soup tastes good.静态性质无进行时
这汤的味道不错
The cook is tasting the soup.动态动作有进行时
厨师在尝汤的味道
总之系动词有无进行时态应随系动词的意义或其语境变化而变化我们在概述某一动词的进行时态时不能笼统地说feelsmell无进行时应指出其意义及其语用环境例如smell的用法可见一斑
①smell作嗅觉的能力时虽是实义动词但指的是一种性质的存在状态不能用于进行时态常与can, could, be able to连用
The camels can smell the water a mile off.
骆驼能嗅出一英里外有水
②指嗅闻的动作时实义动词可用于进行时态
The girl is smelling the flower.
这姑娘正在闻那朵花
③smell指含有……气味发出……气味等事物性质时半系动词无进行时态
The dinner smells good.
这饭菜闻起来真香
2系动词的时态与形容词的比较级连用的问题
某些含有变化意义的动态系动词如get, become, grow, turn等的进行时态可与形容词的比较级连用表示渐进过程其意思是越来越……例如
He is growing taller and taller.
他长得越来越高了
Our life is getting better and better.
我们的生活是越来越好了
The things are getting worse.
情况是越来越糟了
3所有半系动词的被动语态要分情况讨论
英语中某动词在作系动词用时无被动语态而作实义动词用时才有被动语态二者不可混为一谈例如
The apple is tasted good.
因为taste此时是系动词尝起来之意指的是苹果的性质无被动语态
但我们可以说
The apple is tasted by me.
这苹果被我尝了一下
taste此时指尝一尝这一动作有被动语态
因此在平时的英语教学和学习之 要有意注意半系动词在具体的语言环境中到底是系动词用法还是实义动词用法要注意区分识别
4瞬间动态系动词能否与时间段连用的问题
英语中某些表示瞬间意义的系动词不能与for+时间段since+时间点how long until+时间,by + 时间so far等直接连用例如
①不能说He has become a teacher for 2 years.
应改为He has been a teacher for 2 years.
②不能说He has turned writer since 3 years ago.
应改为He has been a writer since 3 years ago.
或It is three years since he turned writer.
③不能说He got angry until his child came back home.
应改为He didnt get angry until his child came back home.
5系动词能接几种表语从句
系动词除了接adj.\n.\prep.短语某些adv.以外还可接以下几种表语形式
①能接as if/as though表语从句的系动词有look看起来smell闻起来sound听起来feel觉得appear显得seem似乎例如
It looks as if we are going to have snow.
看样子天要下雪了
He looked as if he had just stepped out of my book of fairy tales.
他看来好像刚从我的童话故事中走出来似的
She seemed as if (though) she couldnt understand why Laura was there.
看来她好像不能理解为什么劳拉呆在那儿
It sounds to me as though theres a tap running somewhere.
我好像听到某处水龙头流水的声音
She felt as if her head were splitting.
她仿佛觉得她的头要裂开了
The river appeared as if enveloped in smog.
那条河好像笼罩在烟雾之中
It seems as if it were spring already.
好像已是春天了
②可用于It+系动词+that从句结构的有seem, appear, 不可用be, look如
It seemed that he had made some serious mistakes in his work.
好像他在工作中犯了严重错误
It appeared that he was talking to himself.
好像他在自言自语
③能用不定式作表语的系动词有be, seem, get, look, appear, prove, grow.
Her job is to look after the children.
她的工作是照料孩子们
He seems not to look after the children.
他好像不是她的父亲
She looks to be a young girl of twenty year-old.
她看起来像是一个20岁的年轻姑娘
He didnt appear to dislike it.
看不出他憎恨此事
My advice proved to be wrong.
我的建议证明是错误的
He will grow to like this work gradually.
他会逐渐喜欢这个工作的
④能与there连用的系动词有be, appear, seem.
There appeared to be only one room.
那儿好像只有一个房间
There seems(to be)no need to go.
似乎没有必要走
6能用两种否定形式的系动词有两个seem, appear.
It doesnt seem that we can get our money back.
= It seems that we cant get our money back.
He seems not to be her father.
= He doesnt seem to be her father.
The baby doesnt appear to be awake.
= The baby appears not to be awake.
7后接作表语的过去分词可构成系表结构
能构成系表结构的系动词通常有两个第一个是常见的be(is, am, was等)第二个是get口语中常用当二者作系动词用时它们均表示一种存在状态而不表示被动动作当二者作助动词用时后接作谓语的过去分词构成
Be + 过去分词常可以用Get+过去分词来代替但是并不是be系动词总是可以用get来代替Get+过去分词常用于以下两种情况
1表示偶然的突发性的意想不到的被动动作的结果或状态
Last night I got caught in the downpour.
昨夜我被雨淋了表示意想不到
The new car got scratched.
新车给刮坏了表突发性
著名学者教授在论文Get-Passive研究中指出Get+过去分词的被动语态是一种新兴的被动语态形式相对来说它的使用还没有Be+过去分词构成的被动语态那么广泛一般限于和非正式但它却有着用得愈来愈多的趋势是一种的语言现象[1]
2表示对自身所作的事如get dressed, get lost等
John got injured while playing football last Saturday.
约翰上周星期六踢足球时受了伤
They got married last month.
他们上个月结婚了
另外要注意区分系表结构与被动语态结构的用法
8.系动词与动词的区别　　系动词亦称联系动词Link Verb作为系动词它本身有词义但不能单独用作谓语后边必须跟表语亦称补语构成系表结构说明主语的状况性质特征等情况但是有些系动词又是实义动词该动词表达实义时有词义可单独作谓语例如　 He felt ill yesterday.　 他昨天病了felt是系动词后跟补足语说明主语情况　 He fell off the bike.　 他从自行车上摔下来fell是实义动词单独作谓语表示动作中状态的词叫做动词根据其在句中的功能动词可分为四类分别是实义动词系动词助动词情态动词但是有些情况下有些动词是兼类词例如　 We are having a meeting.　 我们正在开会have是实义动词　 He has gone to New York.　他已去纽约have是助动词动词根据其后是否带有宾语可分为两类分别是及物动词不及物动词英语缩写形式分别为vt. 和vi.但是同一动词有时可用作及物动词有时可用作不及物动词例如　 She can dance and sing. 她能唱歌又能跳舞sing在此用作不及物动词　 She can sing many English songs. 她能唱好多首英文歌曲sing用作及物动词连系动词多有自己的意思但不能独立作谓语必须与表语名词形容词或与之相当的词类从句一起构成合成谓语最常用的连系动词为be系动词即完全连系动词另外还有lookturnfeelgetbecomesoundsmellstandgoremain等半连系动词无论是完全连系动词还是半连系动词后面都有表语半连系动词是由实意动词变来的分辨该动词为实意动词还是半连系动词可以尝试用比较法和替换法比较下列各组句子
(1) A Please look at the blackboard请看黑板
B He looked a perfect fool他看上去是个十足的神经病
(2) ATurn to Page 16翻到 16页
BHe turned traitor to his country他背叛了祖国
(3)AHe felt it his duty to help others
他认为帮助别人是自己的责任
BI felt very hungry after a long walk
走了一段长路我感到很饿
(4)A.Get me some ink给我一些墨水
BOur motherland is getting stronger and stronger
我们国家变得越来越强大了
(5)ASuch words do not become a scholar
那样的话不像出自学者之口
BSome of the fields became covered with water
一些田地覆盖着水
(6)AThis black key on the piano won''t sound
这钢琴上的黑键按下去不响
B The story sounds interesting
这故事听起来很有趣
(7)A.I am sure I smell gas我肯定闻到了煤气味
BThe　flowers smell sweet花朵散发芳香
(8)AHe was too weak to stand他太虚弱不能站立
BHolding the note in his handhe stood there dumbfounded
他拿着钞票站在那里目瞪口呆
(9)AHe goes to school early every morning.
他每天早上很早上学
B They went mad他们发狂了
(10)A I remained 3 weeks in Paris
我在巴黎逗留了三周
BHe never remained satisfied with his success
他从不满足于自己的成绩分析以上10组句子我们不难看出B组动词均为连系动词因为如果我们把动词 be是的适当形式替代斜体动词句子能够成立后面的成分即是表语
1He was a perfect fool
2He was a traitor to his country.
3I was very hungry after a long walk
4Our motherland is stronger and stronger
5Some of the land was covered with water
6The story is interesting
7The flowers are sweet
8Holding the note in his handhe was there dumbfounded
9They were mad
10He was never satisfied with his success
反之如果把 be是动词的适当形式替代 A组动词句子则不能成立无法解释A组动词均不为连系动词
*lPlease be at the blackboard
*2Be to Page l6
*3He was if his duty to help others
*4Be me some ink
*5Such words are not a scholar
*6The black key on the piano won''t be
*7I am sure I am gas
*8He was too weak to be
*9He is to school early every morning
*10I was 3 weeks in Paris
另外半连系动词是由实意动词变来的所以把含有半连系动词的句子改为疑问句时一定要用助动词
例如1 Do they look tired
2Has she got ready
3Did it become much more expensive to travel abroad
不论完全连系动词或半连系动词它们都有时态的变化但有些半连系动词从形式上看像是现在进行时实际上并不表示动作正在进行而是表示渐渐的意思或表示一种感情色彩
1It's getting warmer and warmer
天渐渐暖和起来了
2Are you feeling better now
你现在好点了吗
因为本属于不及物动词所以没有被动语态
