知识点名称:可数名词(单数名词,复数名词),副词的比较级,副词的最高级,副词,动名词,主谓一致

考点名称:可数名词(单数名词,复数名词)
  • 可数名词:
    是指能以数目来计算,可以分成个体的人或东西;
    因此它有复数形式,当它的复数形式在句子中作主语时,句子的谓语也应用复数形式。
  • 名词单数变复数的规则:
    情况构成方法例词读音
    一般情况在词尾加-sdesk→desks
    map→maps
    -s在清辅音后发/s/
    day→days
    girl→girls
    -s在元音和浊辅音后发/z/
    以s,x,ch,sh结尾的词在词尾加-esbus→buses box→boxes watch→watches fish→fishes-es发/iz/音
    以辅音字母加-y结尾的词变y为i再加-esfamily→families
    factory→factories

    -s发/z/音
    巧记以f\\fe结尾的可数名词复数
    妻子骑牛拿起刀,wife,calf,knife ↑
    追得贼狼满街跑,thief,wolf →→→变f或fe为v,再加es
    碰倒架子丧己命,shelf,self,life ↓
    手帕树叶半空飘。handkerchief,leaf,half ↓
  • 名词复数的不规则变化:
    1.不规则形式:
    child→children(儿童)
    man→men(男人)
    woman→women (女人)
    an Englishman→two Englishmen(英国人)
    foot→feet(脚)

    news是不可数名词。

    5.表示由两部分构成的东西,
    glasses(眼镜) trousers (长裤) clothes(衣服)
    若表达具体数目,要借助数量词pair(对,双)a pair of glasses  two pairs of trousers suit(套)

考点名称:副词的比较级,副词的最高级
  • 副词的比较级和最高级:
    当两种物体之间相互比较时,我们要用形容词或副词的比较级;
    当相互比较的物体是三个或三个以上时,我们就要用形容词或副词的最高级。
    副词比较级和最高级的变化规则和形容词相似。
  • 副词比较级的变化规则:

    一、规则变化<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />

    1.一般在词尾直接加erest。hard—harder—hardest ;long-longer-longest

    2.以不发音的字母e结尾的单词在词尾直接加rst。nice-nicer-nicest

    3.以辅音字母+y结尾的词,把y变为i,再加erest。early—earlier—earliest 
    4.重读闭音节,末尾只有一个辅音字母,双写这个辅音字母,再加erest,例如,big-bigger-biggest

    5.部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级, carefully—more carefully—most carefully

    二、不规则副词的比较级和最高级

     原级比较级 最高级 
     well betterbest 
     badlyworse worst 
     muchmore most 
     little lesslest 
     far farther(指距离)farthest(指距离) 
     further(指距离和抽象概念)furthest(指距离和抽象概念) 

  • 以ly结尾的副词,比较级有两种情况:
    一种单词里本身就以结尾early;
    另一种是由形容词+变为的副词 slowly,happily ,easily,他们改为比较级时 是不一样的。
    例如:第一种情况,直接进行词尾变化early-earlier;
    而第二种情况, 就要在副词原级前面+more,构成比较级。
    因此,easily 的比较级应该是:more easily 。
  • 副词等级的用法:
    一、原级的用法

    1.只能修饰原级的词,very,quite,so,too。例如:
    He is too tired to walk on.他太累了以至于不能再继续走了。

    Tom runs as fast as Mike.汤姆和迈克跑得一样快。
    Tom runs twice as fast as Mike.汤姆跑得速度是迈克的二倍。
    (2)“甲+助动词+not+动词原形+as/so+副词原级+as+乙”甲不如乙…例如:
    He doesn’t walk as slowly as you.他走路不像你那样慢。

    二、比较级的用法

    I got up earlier than my mother this morning.我今天早晨起床比我妈妈还早。
    He runs three times faster than his brother.他跑的速度比他弟弟快三倍。
    (2)“甲+实意动词+副词比较级+than+anyother+单数名词(+介词短语)”表示“甲比同一范围的任何一个人/物都……”,含义是“甲最……”。例如:
    Mike gets to school earlier than any other student in his class.
    = Mike gets to school earlier than any of the other students in his class.迈克比他们班上任何一个其他的同学到校都早。
    = Mike gets to school earlier than the other students in his class.迈克比他们班上其他的同学到校都早。
    = Mike gets to school earliest in his class.迈克在他们班到校最早。
    注意:Mike gets to school earlier than any student in Tom’s class.迈克比汤姆班上任何一个学生到校都早。(迈克和汤姆不是同一个班)
    (4)“比较级+and+比较级”表示“越来越……”。例如:
    He is getting taller and taller.他变得越来越高了。
    The flowers are more and more beautiful.花儿越来越漂亮。
    He does his homework more and more carefully.他做作业越来越认真了。

    The more careful you are,the fewer mistakes you’ll make.你越认真,犯的错误越少。
    (6)“特殊疑问词+实意动词+副词比较级,甲or乙?”例如:
    Who draws better,Jenny or Danny?谁画得比较好,詹妮还是丹尼?

    三、最高级的用法
    最高级常用句型结构
    (1)“主语+实意动词+(the)+副词最高级+单数名词+in/of短语”表示“……是……中最……的”。例如:
    I jump (the) farthest in my class.我是我们班跳得最远的。
    (2) “特殊疑问词+be+the+副词最高级+甲,乙,or丙?”用于三者以上的比较。例如:
    Which season do you like (the) best,spring,summer or autumn?你最喜欢哪一个季节,春天,夏天还是秋天?
    (3)“特殊疑问词+be+the+最高级+甲,乙,or丙?”用于三者以上的比较。例如:
    Which country is the largest,China,Brazil or Canada?哪一个国家最大,中国,巴西还是加拿大?

考点名称:动名词
  • 动名词:
    如果一个动词加上了ing变成了名词,那么这个词称动名词。 动名词是一种兼有动词和名词特征的非限定动词。
    它可以支配宾语,也能被副词修饰。
    由于动名词是由动词变化而来,它仍保留着动词的某些特征,具有动词的某些变化形式,用以表达名词所不能表达的较为复杂的意念。
    动名词的名词特征表现在它可在句子中当名词来用,作主语、宾语、表语、定语。
  • 动名词的结构和形式:
    动名词的否定结构:
    动名词的否定结构由not 动名词组成。如:
    Trying without success is better than not trying at all. 实验没有成功也比不实验好。
    He hated himself for not having work hard. 他悔恨自己没有用功。
    I’m sorry for not having telephoned you before. 很抱歉,没有早给你打电话。
    He felt sorry for not having done the work well. 他为没有把工作做好感到难过。
    I fancy it has done you a lot of good not going. 我看不去对你倒好了。
    (not going 是动名词一般式的否定形式)
    There is no denying the fact that he si diligent.
    (no denying 也是动名词一般式的否定)

    动名词复合结构:
    通常情况下,动名词的逻辑主语为谓语动词的主语。如果动名词动作的发出者不失谓语动的主语时,则需要有自己的逻辑主语物主代词或名词所有格加动名词就构成了动名词的复合结构,这种结构在句中可以作主语,宾语等。
    (1)逻辑主语是有生命的名词作主语时,必须用名词或代词所有格,作宾语时(尤其在口语中),也可用名词普通个或人称代词宾格。如:
    Do you think my going there will be of any help?
    你看我去会有什么帮助吗?(宾语)
    The student’s knowing English well helps him in learning French.
    这位学生通晓英语对他学法语很有帮助。(主语)
    Do you mind my(me) smoking ? 你介意我抽烟吗?(宾语)
    They insist on Mary’s (Mary) going with them there.
    他们坚持要玛丽跟他们一起去那儿。(介词宾语)
    (2)逻辑主语是无生命名词是,通常只用名词普通格。如:
    Do you hear the rain pattering on the roof?
    你听见雨点打在屋顶上了吗?
    Is there any hope of our team winning the match ?
    我们对赢得比赛有希望吗?
    (3) 逻辑主语是指示代词或不定代词this that , somebody , someone , nobody, none, anybody, anyone 时,只用普通格。如:
    She was woken up by somebody shouting outside.
    她被外面喊叫的人吵醒了。

    动名词的形式(一般式,完成式和被动式):
    (1) 动名词的一般式所表示的动作与谓语动词所表示的动作同时发生,或在谓语动词表示的动作之后。如:
    We are very interested in collecting stamps. 我们对集邮很感兴趣。
    His coming will be of great help to us . 他来对我们大有帮助。
    但是有些明确表示时间的动词和介词 after, on,upon, 或for之后,常用一般式代替完成式,表示动作发生在谓语动作之前。如:
    I shall never forget seeing the Great Wall for the first time.我永远不会忘记第一次看到长城的情景。
    On hearing that bad news , the mother couldn’t help crying. 一听到这个糟糕的消息,母亲就禁不住哭了起来。
    Excuse me for coming late. 我来晚了,请原谅。
    Thank you for giving us so much help. 谢谢你给了我们这么多帮助。
    (2) 动名词的完成式所表示的动作或状态在谓语动词之前完成或结束。
    He regrets not having taken part in the work. 他后悔没有参加这项工作。
    We were praised for having finished the work ahead of time. 我们因提前完成了这项工作而受到了表扬。
    (3)动名词的被动式:当动名词的逻辑主语是行为承受者时,用被动语态。如:
    I like being given harder work. 我喜欢接受难点的工作。
    She is proud of being admitted into the university. 她为被大学录取而感到自豪。
    The meeting was put off without his having been consulted. 会议延期并未和他商量。
    He doesn’t mind having been criticized. 他不介意过去受到的批评。

  • 动名词与现在分词的关系:
    动名词它在形式上与现在分词相同,都是在动词原形的词末加-ing。在现代语法中,这两种形式同视为"-ing形式"。
    这两种形式的另一个相同之处是:
    它们都是由动词变化而成的,它们都保留了动词的某些特征,它们都能带自己的宾语、状语,而构成动名词短语或是现在分词短语去担当句子成分。
    例如:
    Speaking in the public,he will surely be very cheerful .
    (现在分词短语,作状语)他在公众场所讲话时总是兴高采烈的。
    She hates speaking in the public.
    (动名词短语,作宾语)她不喜欢在公众场所讲话。

    动名词和现在分词都可以用于系动词之后作表语,区别方法是:
    ①作表语的动名词与主语指的是同一件事,此时系动词相当于“是”,通常把主语和表语的位置互换,语法和意思不变,例如:
    My hobby is swimming.可改为Swimming is my hobby.(可将原句中的主语与表语位置互换)
    ②现在分词作表语主要用以说明主语的性质,不能与主语互换位置,例如:
    The story is interesting .不可改为:Interesting is the story.
    2.动名词和现在分词都可以用作定语来修饰名词,两者的区别在于:
    动名词修饰名词时主要表示该名词的用途,而现在分词修饰名词时性质、状态或动作等。试比较:
    ①a swimming boy和a swimming suit
    前者的意思是“一个正在游泳的男孩”,即a boy who is swimming,现在分词swimming 表示被修饰名词boy的动作;
    而后者的意思是“游泳衣”,即a suit for swimming,动名词swimming表示suit 的用途。
    ②a sleeping child 和 a sleeping car
    前者的意思是“一个正在睡觉的孩子”,即a child who is sleeping,现在分词sleeping 表示被修饰名词 child 正处于的状态;
    而后者的意思是“卧车(被用来睡觉的车厢)”,即 a car which is used for sleeping,动名词 sleeping 表示car 的用途。

  • 动名词用法口诀:
    动名词常泛指,句法作用宾/表/定与主,时态/语态之形式,一般/完成/被动式。
    Being done 系被动,不含任何进行意。用作主语请留意,常用it作形式主语,不指未来发生事,表达的信息系已知。
    用作表语请记清,作用相当一名词,检验方法很简单,主与表换位能成立。
    用作定语也易辩,表示名词之用途。
    用作宾语稍复杂,关键留意谓语动词(跟动名词作宾语的常用动词附后),时态同谓动作比较,先于谓动用完成式,其逻辑主语不固定,在句中/句外均有之。
    否定式其前加not,复合式其前加物主词,非句首宾格词也可用,尤其口语中更如此。
    说明:1、主-----主语 2、宾-----宾语 3、表------表语 4、定------定语 5、谓动---谓语动词

    动名词的用法:
    一、动名词作主语 
    1. 直接位于句首做主语。例如:   
         Swimming is a good sport in summer.   
    2. 用 it 作形式主语,把动名词(真实主语)置于句尾作后置主语。   
    动名词做主语时,不太常用 it 作先行主语,多见于某些形容词及名词之后。例如:
    It is no use telling him not to worry.   
    常见的能用于这种结构的形容词还有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。   
    注意:important,essential,necessary 等形容词不能用于上述结构。   
    3. 用于“There be”结构中。例如:   
    There is no saying when he'll come.很难说他何时回来。    
    4. 用于布告形式的省略结构中。例如:   
    No smoking ( =No smoking is allowed (here) ). (禁止吸烟)   
    No parking. (禁止停车)   
    5. 动名词的复合结构作主语   
    当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构
    (这时,名词或代词的所有格做动名词的逻辑主语)。
    动名词的复合结构也可以在句中作主语。例如:    
    Their coming to help was a great encouragement to us.   

    二、动名词作宾语
    1.作动词的宾语   
    某些动词后出现非限定性动词时只能用动名词作宾语,不能用不定式。常见的此类动词有:
    admit, appreciate, excuse, stand, advise, allow, permit, avoid,  consider, enjoy, finish     
    They went on walking and never stopped talking.他们继续走,说个不停。 
    I found it pleasant walking along the seashore.在海滩上走真是乐事。   
    Mark often attempts to escape being fined whenever he breaks traffic  regulations.   
    每当马克违反交通规则时,他常常企图逃避罚款的处分。    
    2.作介词的宾语   
    We are thinking of making a new plan for the next term. 我们正考虑为下学期制定新的计划。   
    Shall we have a rest or get down to doing our work? 我们休息呢还是开始干活?   
    3.作形容词的宾语   
    The music is well worth listening to more than once.  这种曲子很值得多听几遍。   
    We are busy preparing for the coming sports meet. 我们正为马上到来的运动会忙着做准备。

    三、动名词作表语
    动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。
    表语、动名词与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。   
    Your task is cleaning the windows.   你的任务就是擦窗户。
    (Cleaning the windows is your task.)   
    What I hate most is being laughed at.  我最痛恨的就是被别人嘲笑。
    (Being laughed at is what I hate most.)

    四、动名词作定语
    动名词作定语往往表示被修饰词的某种用途。如:   
    a walking stick =a stick for walking=a stick which is used for walking   
    a washing machine=a machine for washing=a machine which is used for washing    
    a reading room=a room for reading=a room which is used for reading   
    a measuring tape=a tape for measuring=a tape which is used for measuring   
    sleeping pills=pills for sleeping=pills which is used for sleeping

  • 动名词是非限定动词的一种形式,由动词原形+ing构成。它既有动词的特征,又有名词的特征,故称。
    动名词也有时态和语态的变化,如表所示(以及物动词write为例),不及物动词没有语态的变化。
    时态、语态主动被动
    一般式writingbeing  written
    完成式
    having written
    having been written
  • 动名词使用注意事项:
    1) 动名词做主语时,谓语动词为单数
    2) 在动名词和不定式中,作为介词的宾语是动名词
    3) 动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语
    例:I would appreciate you calling back this afternoon.
    4) 有些词后只能接动名词
    acknowledge;admit; advise;advocate;allow;appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny;
    detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can’t help;
    hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent;
    recall; report; resent; resist; risk; suggest; understand...
    5) 另外还有一些接-ing形式的常用说法
    it’s no good; it’s no/little/hardly any/ use; it’s not/hardly/scarcely use; it’s worthwhile; spend money/time; there’s no;
    there’s no point in; there’s nothing worse than; what’s the use/point
    6) 有些词后面加不定式和动名词均可
    remember,forget,try,stop,go on,continue,stop,regret,cease,mean后面均可用不定式和-ing形式,但意义截然不容。
    例:remember to do/doing:
    ①I remembered to post the letters.(指未来/过去未来将要做的动作)
    ②I remembered posting/having posted the letters.(我记得做过这个动作)
     forget与remember的用法类似。
     regret的用法:
    ①I regret to inform you that…(我很遗憾地通知你……)
    ②I regretted having left the firm after twenty years.(为了“二十年前的离开”而遗憾。)
     try to(努力)与try +–ing(试验):
    ①You really must try to overcome your shyness.
    ②Try practicing five hours a day.
考点名称:主谓一致
  • 英语中的一致主要包括主语和谓语在人称和数上的一致、时态一致、名词和其代词的一致。
    主语和谓语保持一致叫主谓一致,即谓语动词的形式必须随着主语单、复数形式的变化而变化。
  • 主谓一致原则:
    1、语法上的一致
    所谓语法一致原则,即主语和谓语的语法形式在人称和数上取得一致。
    谓语的单、复数形式依据主语的单、复数形式而定:主语为复数,谓语动词用复数;主语为单数或者是不可数名词,谓语动词用单数。
    China belongs to the Third World. 中国属于第三世界。

  • "表里不一"现象:
    主谓一致中的"表里不一"现象
    和主语必须在人称和数上保持一致,最基本的原则是:单数主语用单数动词,复数主语用复数动词.但在实际使用当中情况比较复杂,现在学生常犯的主谓一致错误归纳整理如下
    1,"more than one +名词"作主语时,谓语动词常用单数.例如:
    More than one teacher gets the flowers. 不止一个教师得到了花.
    2,"many a +名词"作主语时,从意义上看是复数,但谓语动词常用单数.例如:
    Many a student has been sent to plant trees. 很多学生被派去植树.
    3,"half of,the rest of,most of,all of及百分数或分数+of 等后接名词"作主语时,谓语动词形式根据of后的名词而定.例如:
    Three fourths of the surface of the earth is covered with water.地球表面四分之三为水所覆盖.
    4,all指人时,动词用复数;all指物时,动词用单数.例如:
    "All are present and all is going well." 所有人全部到场了,一切进展顺利
    5,what引导的主语从句,谓语动词可视表语而定:表语是单数名词时,动词用单数,相反,则用复数.例如:
    What they want to get are a number of good books.他们想得到的是大量的好书.
    6,and连接的两个单数名词前若用each,every,no修饰,该名词短语作主语时,谓语动词用单数形式.例如:
    No book and no pen is found in the schoolbag.书包里没有书和钢笔.
    7,当主语后面有as well as,with,along with,together with,but,like,rather than,except,逗号加and连接几个名字等引导的短语时,谓语动词要与最前面的主语保持一致.例如:
    My father as well as his workmates has been to Beijing. 我父亲和他的同事曾去过北京.
    8,each作主语的同位语时,谓语动词由主语来决定,与each无关.例如:
    They each have a bike. 他们每人有一辆自行车.
    9,动词不定式,动词-ing形式短语作主语时,谓语动词常用单数.例如:
    Going out for a walk after supper is a good habit.晚饭后出去散步是一个好习惯.
    10,the following作主语时,谓语动词的数与后面名词的数保持一致.例如:
    The following are good examples下面是一些好例子.
    11,以-ics结尾的学科名词,如politics,physics,mathematics等作主语时,谓语动词用单数.以-s结尾的名词news,works,plastics等同属此类.例如:
    Politics is now taught in all schools. 现在各学校都开设政治课.
    当以-ics结尾的学科名词表示"学科"以外的意义时,用作复数,如:mathematics(运算能力)politics(政治观点)economics(经济意义)等
    12,有些用来表示由两个对应部分组成一体的名词复数(trousers,glasses,shoes.shorts.scissors.scales等)作主语时,前面若有"一条","一副","一把"之类的单位词,动词用单数;若没有单位词或单位词是复数,则谓语动词用复数.例如:
    The shoes are all right. 这些鞋子都很合适.

  • 以-s结尾的名词作主语的主谓一致:
    英语可数名词的规则复数形式是在词尾加-s或-es,但是有一些以-s结尾的名词并不是可数名词。
    它们用法多样,造成了实际使用上的困难,以下详述了以-s结尾的名词作主语的主谓一致问题。
    (一)以-s结尾的疾病名称作主语的主谓一致问题
    (二)以-s结尾的游戏名称作主语的主谓一致问题
    (三)以-s结尾的地理名称作主语的主谓一致问题
    (四)以-ics结尾的学科名称作主语的主谓一致问题
    (五)其它以-s结尾的名词的主谓一致问题

    集合名词的主谓一致原则:

    集合名词作主语时,主谓一致关系是一个较为复杂的问题.对此类问题我们可以从"数"的角度分为四类.
    1)单数—复数型.凡是有复数词尾变化形式的集合名词都属于此类。如:
    a class—classes; a family—families; a government—governments; an army—armies; a people—peoples; a group—groups; a crowd—crowds; a crew—crews等。
    这类集合名词强调的是整体性,即当作一个整体或多个整体来看待。属于这类集合名词的单数作主语时,谓语动词用单数;
    复数形式作主语时,谓语动词用复数。
    【例如】
    A big crowd often gathers on the square every morning.
    每个上午 一大群人经常聚集在广场上
    The government has decided to pass the bill.
    政府已决定通过这一法案
    There are huge crowds in the streets on Sunday.
    星期天有大群大群的人在街上。
    There are many English-speaking peoples in the world.
    在世界上有许多讲英语的人
    但应注意,这类集合名词的单数形式有时表示复数概念,所以这些集合名词的单数形式也可归为"单复同形型"中.
    2)单数型.这类集合名词表示的是人或事物的整体,即把这类人或事物的全部包括在内,所以只有单数形式.如作主语,谓语动词常用单数。
    这类名词常见的有:humanity,mankind,proletariat等.
    【例如】The proletariat is the greatest class in the history of mankind. In the fields of production and scientific experiment,mankind makes constant progress.
    3)复数型.这类集合名词在形式和内容上是相互矛盾的,就是说它们只有单数形式,但表达的都是复数概念。它强调的是集体中的个体性.这类名词有:police,cattle,faculty,flock,machinery,vermin,personnel等.它们作主语时,谓语动词要用复数.
    【例如】The police have caught the murder.
    Our personnel are very highly trained.
    The vermin are very dangerous.
    4)单复同形型.这类集合名词的单数形式既可表示单数也可表示复数.作主语时,用单数动词或复数动词均可,有时意义区别不大.
    【例如】The school teaching staff are (is) excellent.
    The public is (are) requested not to litter in the park.
    The teaching profession claim(s) to be badly paid.
    这类集合名词常见的有:class,family,team,crew,board,herd,committee,party,jury,enemy,audience等.
    根据说话人的心理意向若把这个集合名词所代表的人或事物看作一个整体,就认为是单数,用单数动词;
    若把它所代表的人或事物看作若干个个体的话,就认为其为复数,用复数动词。
    试比较:The football team is playing well.
    那个足球队打得非常漂亮.
    The football team are shavings bath and are then coming back here for tea. 足球队员们正在洗澡,然后来这里吃茶点。
    The family is a very happy one.那个家庭是一个非常幸福的家庭。
    That family are very pleased about the news of William's success. 全家人对威廉的成功都感到很高兴。

    巧记主谓一致原则:
    单单复复最常见,集体名词谓用单,如若强调其成员,复数谓语记心间。
    有些名词谓常复,people,police即这般。主语单数后接介,谓语单数介无关,
    many a作主语也如此,谓语动词应用单。or、nor、but also、there be,近主原则挂嘴边。
    关系代词定主语,谓语根据先行词判。不定式短语、动名词,主语从句谓全单。
    时间、货币与距离,谓语多单复少见,rest,means,fol1owing等,意义决定其复、单。
    none,all,half of等,of之宾语定答案。还有分数、百分数,仍据of之宾定复、单。
    代词all指人谓复数,all指事情谓用单。量词用法请注意,谓语要随量词变。
    and连接两名词,身兼两职一定冠,no,each,every后单名,两件(种)事(物)系一概念,
    以上情况请记清,谓语动词全用单。形容词带the一类人,姓氏复数加定冠,
    -s结尾的海峡、山脉与群岛,谓语用复勿用单。neither,either,each,用作主语谓全单。
