初中英语被动语态

1-1 当句子的主语为动作的承受者即受动者，动词e69da5e887aae799bee5baa631333264643135用被动语态。Eg. John helped Peter. （John是动作的施行者，而Peter是动作的承受者即承受者。） Peter was helped by John. （Peter是句子的主语，而且是动作的承受者，所以用被动语态。）1-2 被动语态的构成：be + 动词的过去分词2. 特别提醒：被动语态的时态和人称的变动都是由动词be作改变的，不论发生什么改变，动词的过去分词(v+ed或不规则的分词) 都不改变。时态用的助动词和人称代词由被动语态句子中的主语，即动作的承受者，所决定。2-1 Eg. He cleans the room everyday.  The room is cleaned (by him) everyday. (一般现在时的被动语态构成: is / am / are + 动词的过去分词)2-2 Eg. They have brought many toys since last week. Many toys have been brought (by them) since last week. (现在完成时的被动语态构成：has/have + been + 动词过去分词。)2-3 Eg. They are meeting the foreigners at the gate. The foreigners are being met (by them) at the gate. (现在进行时的被动语态构成：is/ are/ am + being + 动词过去分词)2-4 Eg. They will build some new buildings next year.  Some new buildings will be built (by them) next year. They are going to draw a new picture tomorrow.  A new picture is going to be drawn tomorrow.(一般将来时被动语态构成：will + be +动词过去分词, 或is/am/are going to +be + 动词过去分词)2-5 Eg. Father has been painting the room all morning.  The room has been being painted (by father) all morning.(仅作了解：现在完成进行时的被动语态：has/ have + been+ being + 动词过去分词)2-6 Eg. They wrote the book last year. The book was written (by them) last year. （一般过去时的被动语态构成：was/ were+动词过去分词）2-7 Eg. The children had broken the window when the teacher arrived. The windows had been broken (by the children) when the teacher arrived. (过去完成时被动语态构成had + been + 动词过去分词。)2-8 Eg. She was reading the book at 8:00 last night.  The book was being read at 8:00 last night. (过去进行时被动语态构成：was/ were being + 动词过去分词)2-9 Eg. They said they would cook some food.  They said some food would be cooked. They said he was going to buy a new house.  They said a new house was going to be bought.(过去将来时被动语态构成：would +动词过去分词，或：was/were going to be + 动词分词)2-10 Eg. He must finish the work in two days.  The work must be finished in two days. (情态动词被动语态：must/have to/had better/ should/can/could/may/might/need to + be +动词分词) 3． 间接引语中的被动语态：3-1 引述动词是一般现在时的时候，引语的人称根据引述动词前面的主语而作调整，但时态不变。Eg. He often says, “ I was chosen to take part in the exam when I was twelve.” He often says he was chosen to take part in the exam when he was twelve. （人称由引述动词says前面的主语he 决定，但引语的时态不变。）3-2 引述动词为过去时态，引语部分的时态和人陈都按照引述部分进行改变。Eg. He said, “ My father has been hit by a car.”He said his father had been hit by a car. (引语部分的时态和人称都发生了改变。)3-3 从上文可看出：引述动词是过去时态时，被动语态形式的引语改动规则与主动语态形式的引语的改动规则一样，但无论如何，只要是被动语态，它的动词的过去分词总是不改的。）4．几种特殊的情况需要特别注意：4-1. 带介词的双宾语可以有两种改法：eg. They gave him an apple.  He was given an apple.  An apple was given to him. (双宾语中当直接宾语apple 作被动语态句子的主语时，要记得写上介词to。)4-1-1这样的动词有：buy/make/cook sth for sb 或：show/bring/give/take/ send/write/… to sb.4-2. 多词动词的被动语态：eg. She looked after his children.  His children were looked after (by her).4-2-1这样的动词有：look after, look into, talk about, set up, put off, bring about, do away with, look forward to, take good care of 等等词。4-3 It is/was/has been said/reported/known + that + 从句4-4 有些动词在主动语态里不带to，但改为被动语态时要还原tomake/see/have/hear/let sb do sth sb be made/seen/heard/let to do sth eg. The boss made the workers work for a long time.  The workers were made to work for a long time (by the boss).4-5 有些动词在主动语态中带sb doing sth, 改为被动语态时仍用doing stheg. I heard him singing in his room. He was heard singing in his room.4-6 特别区分：当句子中出现suddenly, 具体的时间时，用see/hear sb doing sth的形式当句中出现often, always, sometimes, 或不具体的时间时，用see/hear sb do sth的形式。Eg. 1) I often hear him sing in his room. 2) Yesterday I saw him cross the road. 3) Suddenly they heard someone crying in the forest.4-7 不及物动词没有被动语态：happen, take place, begin, become, go, comeeg. Great changes have taken place in the last two years.4-8 表静态的动词没有被动语态：cost, last, agree with, own4-9 主动形式表示被动意义，通常用于表示sth的功能或效用: write/wash/cut/use/sell/cookeg. The cooker cooks well. The washing machine washes well.注意：动词的搭配：1．带sb to do sth的动词：allow/encourage/help/want/wish/ask/tell sb to do sth, 2．带 to do sth 的动词：hope/agree/decide/want/wish/prefer to do sth3．带 doing sth 的动词：enjoy/practise/think about/doing sth4．几对特殊的例子：remember to do sth (记得要做，但还没做) remember doing sth (记得要做，而且做了) forget to do sth ( 忘记要做，没有做) forget doing sth ( 做了，但忘记已经做了)5．prefer doing sth to doing sth6．look forward to doing sth7．介词后面用doing sth8．动词做句子的主语时用ing形式：Collecting stamps is interesting. 本回答由提问者推荐

被动语态定义　 　英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。　　主动语态表示主语是动作的执行者。　　例如：Many people speak Chinese.　　谓语：speak的动作是由主语many people来执行的。　　被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chinese is spoken by many people. 中文Chinese是动词speak的承受者。　　1. 定义：被动语态，即不知道动作执行者或强调动作承受者的一种语态。例如中文常说：我被他打，这就是一种被动。但有时由于句子结构上的需要也要用被动，例如It is not unusual for workers in that region to be paid more than a month it 在句中作形式主语。而不定式to be paid more than a month是句子的逻辑主语。结合选项全句的意思是：“那个地方的工人一个多月后才得到工资是常有的事”。　　2. 构成：be+past participle(过去分词)(简称P.P.)（+by+动作执行者）（过去分词的概念见上课）　　3. 当主动语态要被改成被动的时候，我们把原句的宾语提前，作为改句的主语，主语后置，作为宾语。因此有一点要注意，不及物动词由于不加宾语，没有被动形式，但不及物动词如果与某些介词构成介词短语，可以用被动。例如The fire had been put out before the fireman arrived. Put是不及物动词，但put out是及物动词　　4. 应用到各种时态和句型,如下：　　① 一般式（一般现在，一般过去，一般将来）：am, is, are, was, were, is going to be , will be+done.ie. Once environmental damage is done, it takes many years for the system to recover. 本句的意思是：“环境一旦遭到破坏，需要多年时间才能恢复过来。”do作为及物动词有“引起，产生”的含义，do damage的意思是“造成破坏”。主语damage是及物动词do的动作对象，谓语应当用被动语态。同样的，还有，I will mend the machine.相当于The machine will be mended （by me）.　　②进行时（现在进行、过去进行、将来进行）：be+being+P.P. ie.The classroom is being cleaned.　　③ 完成时（现在完成、过去完成、将来完成）：have/has been + P.P.：例如The machine will have been repaired by 3 o’clock this afternoon.再如：My homework has been finished.　　④ 其他时态 以此类推，可得到结果。　　⑤ 情态动词的被动语态：主语 + 情态动词 + be动词 + 动词过去分词，例如Your teeth must be brushed.　　⑥ 不定式的被动语态：to be done例：The no-shows have to be considered when deciding the rate of overbooking.（确定超过接待能力的预定时必须考虑预定了房间却来不了的客人。） 主动语态变为被动的几个特殊情况　 　① 有些动词在主动结构中，后面接不带to的不定式，但如果改为被动，则需把省略的to加上，这类动词有 [let, make, have,help]和感官动词[feel,see,hear,watch,look at,listen to]，如：The boss made my grandfather work 10hours a day.改成My grandfather was made to work for 10 hours a day.　　② 含有宾语从句的主动结构变为被动，通常用it作为被动结构的先行主语，从句放在句子后面/也可采用另一种形式，这类动词有：know, say, believe, find, think, report等　　③ 是所有的主动句都可以变换成被动句，更不是所有的被动句都可以自由变换成主动句。虽然语法原则上允许主动和被动句的互相转换，但有的句子转换后会变成不通顺或不地道的英语句子。因此，在某些题目里，这也成为判断应该用主动还是用被动的依据。　　例：At 5:05 p.m. on Saturday 19th July , there was an accident at the junction of the Main Street and Panda Road when a boy was knocked down off his bicycle by a delivery van. The boy was sent to St. Maria Hospital where he was treated for shock and a broken arm.　　在这段文章里，a boy was knocked down off his bicycle by a delivery van这句被动句强调出读到文章的人最关心的事故的受害者。The boy was sent to St. Maria Hospital这句话则说明了孩子被送到医院的事实，至于是由谁（某个过路人？或肇事司机？）送的不重要。he was treated for shock and a broken arm这句被动句无须说出treat这个动作的发出者，因为在医院，伤病员自然由医务人员处理，无须罗嗦。这样，这段文章就重点突出，条理清楚了。　　④ 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一个宾语仍然保留在谓语后面。多是把间接宾e79fa5e98193e78988e69d8331333332636433语变为主语。这样句子自然些。直接宾语变为主语时，间接宾语要变为某个介词的宾语，介词to可以省略。如His father left him this house.改为This house was left (to) him by his father.　　⑤ 有些动词虽为及物，但宾语并非是动作承受者，不能转换，这些动词有have, hold（容纳）,suit, fit, lack, become（适合）contain, cost, last, mean, suffice（足够）等。　　⑥ 当直接宾语为反身代词、相互代词或宾语前有指代主语的物主代词时不用被动，如I shook my head.我摇摇头。　　⑦ 当宾语为同源宾语（与主句指同一人），动名词，动词不定式或一个从句时不用被动。如John enjoyed seeing the fil,.　　⑧ 在一些固定说法中，有些名词和动词结合的固定说法，不能改We Chinese always keep our word.　　⑨ 某些从不及物动词转化来的及物动词，直接宾语在表示动作的方式或效果时，这些动词在意思上起状语的作用，没有被动The girl kissed her boyfriend good night=The girl said good night to her boyfriend by kissing him.(这个女孩说了晚安并且亲了他的男朋友）　　⑩ 表地点\处所\组织\长度\大小\数量\程度\抽象名词的词做宾语时不用被动.　　

一般现在时：am\is\are+过去分词。来 现在进行时：be动词+being+过去源分词。 现在完成时：have\has+been+过去分词。 一般过去时：was\were+过去分词。 还有就是情态动词加上be+过去分词。 还有许多。我zhidao暂时不列举了。反正就是遵循一个原则：be动词+过去分词。

悬挂 是一个动作 一个东西 它可以被悬挂 就可以用被动语态 如果表示 挂着一个东西 挂着 这种状态的时候 是这个物体的状态 无关动作 就不能用被动了 本回答被提问者采纳

一般就是 be+动词的被动语态

一、被动语态的构成形式 1. 被动语态的基本时态变化 被动语态通常为十种时态的被动形式, 被动语态由be＋过去分词构成，be随时态的变化而变化。以do为例，各种时态的被动语态形式为： 1) am/is/are +done (过去分词) 一般现在时 例Visitors are requested not to touch the exhibits. 2） has /have been done 现在完成时 例All the preparations for the task have been completed, and we're ready to start. 3） am/is /are being done 现在进行时 例A new cinema is being built here． 4） was/were done 一般过去时 例I was given ten minutes to decide whether I should reject the offer. 5） had been done 过去完成时 例 By the end of last year, another new gymnasium had been completed in Beijing. 6） was/were being done 过去进行时 例A meeting was being held when I was there. 7） shall/will be done 一般将来时 例Hundreds of jobs will be lost if the factory closes. 8） should/would be done 过去将来时 例The news would be sent to the soldier's mother as soon as it arrived. 9） shall/will have been done 将来完成时（少用） 例The project will have been completed before July. 2. 被动语态的特殊结构形式 1)带情态动词的被动结构。其形式为：情态动词＋be＋过去分词。 例The baby should be taken good care of by the baby-sitter. 2) 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。 例His mother gave him a present for his birthday. 可改为 He was given a present by his mother for his birthday. 3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。 例Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette. 4）在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。 require.async(['wkcommon:widget/ui/lib/sio/sio.js'], function(sio) { var url = 'https://cpro.baidustatic.com/cpro/ui/c.js'; sio.callByBrowser( url, function () { BAIDU_CLB_fillSlotAsync('u2845605','cpro_u2845605'); } ); }); 例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building. 5) 有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等e799bee5baa6e78988e69d8331333365633862，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。 例The meeting is to be put off till Friday. 3. 非谓语动词的被动语态 v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。 例I don't like being laughed at in the public. 二、 如何使用被动语态 学习被动语态时，不仅要知道被动语态的各种语法结构，还要知道在哪些情况中使用被动语态。 1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。 例 My bike was stolen last night. 2. 借助被动的动作突出动作的执行者。 例 I was given ten minutes to decide whether I should accept the offer. 3. 为了更好地安排句子。 例The well-known person got on the bus and was immediately recognized by people. （一个主语就够了） 三、 It is said that+从句及其他类似句型 一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It＋be＋过去分词＋that从句”或“主语＋be＋过去分词＋to do sth.”。有： It is said that„ 据说,It is reported that„据报道，It is believed that„大家相信，It is hoped that„大家希望，It is well known that„众所周知，It is thought that„大家认为，It is suggested that„据建议。 例It is said that the boy has passed the national exam. （＝The boy is said to have passed the national exam. ） 四、谓语动词的主动形式表示被动意义 1.英语中有很多动词如 break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式 表达被动意义,主语通常是物。 例 This kind of cloth washes well. 注意：主动语态表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。 试比较：The door won't lock． （指门本身有毛病） The door won't be locked． （指不会有人来锁门, 指“门没有锁”是人的原因） 2. 表示“发生、进行”的不及物动词和短语，如：happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。 (window.cproArray = window.cproArray || []).push({ id: "u3054369" });例 How do the newspapers come out? 这些报纸是如何引出来的呢？ 3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。 例Your reason sounds reasonable 五、非谓语动词的主动形式表被动意义 在某些句型中可用动名词和不定式的主动形式表被动意义 。 1． 在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。 例The house needs repairing（to be repaired）．这房子需要修理。 2． 形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。 例The picture-book is well worth reading．（＝The picture-book is very worthy to be read．） 3. 动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。 例 I have a lot of things to do this afternoon． (to do与things是动宾关系，与I是主谓关系。) 试比较：I’ll go to the post office. Do you have a letter to be posted? ( 此处用不定式的被动语态作定语表明you不是post动作的执行者。) 4. 在某些“形容词＋不定式”做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等。 例This problem is difficult to work out .（可看作to work out省略了for me）. 5． 在too„ to„结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。 例This book is too expensive (for me) to buy. 6. 在there be„句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人，用被动形式作定语，重点在物。 例There is no time to lose（to be lost）．（用 to lose可看成for us to lose；用to be lost，谁 lost time不明确。） 7. 在be to do结构中的一些不定式通常应用主动表主动, 被动表被动。然而,由于古英语的影响,下列动词rent,blame,let等仍用不定式的主动形式表示被动意义。 例 Who is to blame for starting the fire? 六、介词in, on, under等+名词构成介词短语表被动意义 表示方位的介词与含动作意义的名词合用，含被动之义，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。 1. “under +名词”结构，表示“某事在进行中”。常见的有：under control（受控制）, under treatment（在治疗中）, under 例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building. 5) 有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。 例The meeting is to be put off till Friday. 3. 非谓语动词的被动语态 v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。 例I don't like being laughed at in the public. 二、 如何使用被动语态 学习被动语态时，不仅要知道被动语态的各种语法结构，还要知道在哪些情况中使用被动语态。 1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。 例 My bike was stolen last night. 2. 借助被动的动作突出动作的执行者。 例 I was given ten minutes to decide whether I should accept the offer. 3. 为了更好地安排句子。 例The well-known person got on the bus and was immediately recognized by people. （一个主语就够了） 三、 It is said that+从句及其他类似句型 一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It＋be＋过去分词＋that从句”或“主语＋be＋过去分词＋to do sth.”。有： It is said that„ 据说,It is reported that„据报道，It is believed that„大家相信，It is hoped that„大家希望，It is well known that„众所周知，It is thought that„大家认为，It is suggested that„据建议。 例It is said that the boy has passed the national exam. （＝The boy is said to have passed the national exam. ） 四、谓语动词的主动形式表示被动意义 1.英语中有很多动词如 break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式 表达被动意义,主语通常是物。 例 This kind of cloth washes well. 注意：主动语态表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。 试比较：The door won't lock． （指门本身有毛病） The door won't be locked． （指不会有人来锁门, 指“门没有锁”是人的原因） 2. 表示“发生、进行”的不及物动词和短语，如：happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。 例 How do the newspapers come out? 这些报纸是如何引出来的呢？ 3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。 例Your reason sounds reasonable 五、非谓语动词的主动形式表被动意义 在某些句型中可用动名词和不定式的主动形式表被动意义 。 1． 在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。 例The house needs repairing（to be repaired）．这房子需要修理。 2． 形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。 例The picture-book is well worth reading．（＝The picture-book is very worthy to be read．） 3. 动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。 例 I have a lot of things to do this afternoon． (to do与things是动宾关系，与I是主谓关系。) 试比较：I’ll go to the post office. Do you have a letter to be posted? ( 此处用不定式的被动语态作定语表明you不是post动作的执行者。) 4. 在某些“形容词＋不定式”做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等。 例This problem is difficult to work out .（可看作to work out省略了for me）. 5． 在too„ to„结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。 例This book is too expensive (for me) to buy. 6. 在there be„句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人，用被动形式作定语，重点在物。 例There is no time to lose（to be lost）．（用 to lose可看成for us to lose；用to be lost，谁 lost time不明确。） 7. 在be to do结构中的一些不定式通常应用主动表主动, 被动表被动。然而,由于古英语的影响,下列动词rent,blame,let等仍用不定式的主动形式表示被动意义。 例 Who is to blame for starting the fire? 六、介词in, on, under等+名词构成介词短语表被动意义 表示方位的介词与含动作意义的名词合用，含被动之义，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。 1. “under +名词”结构，表示“某事在进行中”。常见的有：under control（受控制）, under treatment（在治疗中）, under不着), out of fashion(不流行)等。 例 The plane was out of control (can’t be controlled)． 。 8．“within+名词”结构，“在„„内、不超过„„”。 例He took two days off within the teacher's permission 四. 如何正确使用被动语态 1. 有些动词带有两个宾语，即直接宾语和间接宾语，变被动语态时，可把其中一个宾语变成主语，另一个留在被动结构谓语后面。需要注意的是：若把直接宾语变成被动语态的主语，需要在间接宾语之间加上介词“to”。 eg. He often tells us interesting stories . （主动语态） (window.cproArray = window.cproArray || []).push({ id: "u3054371" });.himbyustotoldoftenarestoriesgInterestin.himbystoriesginterestintoldoftenareWe（被动语态） ▲常带双宾语的词有：tell , show , lend , pass等。 2. 在主动语态中，某些动词之后带有复合宾语，即宾语和宾语补足语，这个复合宾语由动词不定式来充当，to被省略，但在被动语态中，这个to还要还原。 eg. I often hear her sing this popular song . （主动语态） 复合宾语宾语补足语宾语She is often heard to sing this popular song .（被动语态） ▲ 有这种用法的常用动词有：make , let , see , hear , watch , feel , notice等。 3. 有些“be +过去分词”的结构并不是被动语态，它们有可能是“系表结构（即系动词之后由过去分词来充当表语）。” 比较：（1）)()(.FengpingbyclosedisdoorThe.closedisdoorThe被动语态。这个门是由冯平来关的系表结构门是关着的。（2）)()(.MarybybrokenwasglassThe.brokenisglassThe被动语态。的这个玻璃杯是玛丽弄坏系表结构。这个玻璃杯是坏的 4. 只有及物动词和可有宾语的动词+介词词组才可以有被动语态。 eg. )()(.ChinainplacetakenbeenhavechangesGreat.ChinainplacetakenhavechangesGreat错误正确 )()(.seadeeptheinddisappearewasdolphinThe.seadeeptheinddisappearedolphinThe错误 追问 你很皮 本回答被提问者和网友采纳
