一、教法建议
【抛砖引玉】
单元双基学习目标
ⅰ. 四会单词和词组:
pain , in (the) future , be rich in , contain , fat ( n . ) , soft drink , score , scores of , discuss , discussion , at the end ( of )
三会单词和词组: examine , ripe , advise , patient , energy , weight , put on weight , westerner , cause , unhealthy , lose weight , suggestion
ⅱ. 交际英语:
人人都希望自己身体健康,工作顺利,生活愉快。人体就像一部机器,机器需要经常保养才能不停地正常运转,不出故障;人也需要营养合理的饮食、充足的睡眠、必不可少的休息与娱乐。倘若你为了省钱省时间而终日凑合着吃东西;倘若你为了挤出更多的时间对付艰苦的学习而挤掉了睡眠时间;倘若你为了多打工赚钱,几乎舍弃了所有的休息与娱乐。那么,生病就在所难免。万一人生了病就需要去医院诊断出出故障的原因,这时就需要和医生打交道,下面是常用到的语句。
医生用语:
1. what can i do for you ? / what was the matter ? / what's the trouble ?
2. does it hurt here ? / it's nothing serious . / let me examine you . / take this medicine three times a day . / and i advise you not to do …
3. drink plenty of water and have a good rest . / you'd better have a good rest . / you'll be well soon .
4. show me your tongue . / stick out your tongue . / did you cough much ? / fortunately , you only have the flu (流感) . / you'll have to be hospitalized (住院) .
5. how long have you been like this ? / well , let's see . open your mouth and say “ah ”. / keep warm and don't catch cold .
病人用语:
1. i've got a pain ( cough , headache , toothache ) . / i don't feel well . / there's something wrong with … . / this place hurts . / i feel a great pain here . / i feel dizzy (头晕) . / i took some medicine last night , but they didn't help . / doctor , please give me an examination .
2. i've had my temperature taken . i indeed have a fever . / i was hot and cold by turns .
3. i don't feel well , doctor . / i hope it won't last long . / i don't feel like eating anything .
4. i have a sore throat ( 喉咙痛) and my chest hurts . / it started bothering me yesterday afternoon . / i feel hot and feverish . / i'm aching all over .
5. i've been losing sleep . / my whole body feels weak . / i've lost my voice . / my ears are ringing , and my cheeks burning . / i feel a pain in my left leg .
ⅲ. 语法重点:进一步学习提出建议和忠告的句型。
1. i advise you (not) to do … / you'd better (not) do … / i suggest that you (should) do … / why not do … / why don't you do …
2. it's better to be absolutely sure , even if it does take a bit more time and trouble .

5. how / what about doing some shopping here ?
6. i think we'd better send for a doctor .
7. well , if you go on the way you have , you're only going to make things harder for yourself .
8. yes , i suppose so . / yes , i certainly will . / that's a good idea . / yes , but don't you think … ?
【指点迷津】
单元重点词汇点拨
1. contain 作及物动词是“包含;包括;能容纳,能装入”
sea water contains salt .
this auditorium will contain 3,000 people .
〖点拨〗(1) contain 和 include 虽然都有“包含”的意思,但 contain 可用于表示包含所含之物的全部或部分,而 include 则只是包含一部分。试对比:
the parcel contained a dictionary . 那包裹里装的是一本字典。
the parcel included a dictionary . 那包裹里也包括了一本字典。
the tour includes a visit to paris . 这次旅行包括游览巴黎。
the basket contains a variety of fruits . 这篮子装有各种水果。
(2) including 可以作介词连接介词短语。试比较:
many women were waiting to buy that kind of cloth , including my mother .
many women were waiting to buy that kind of cloth , my mother included .
可以这样说,include 着重“被包含者只是整体中的一部分”。contain 着重“内有”。
2. advise 作及物动词是“忠告、劝告、建议”
the doctor advised a soft diet . 医生建议进软食。
〖点拨〗(1) advise + doing
he advised getting plenty of sleep and eating good meals .
(2) advise sb to do 建议某人干……。advise sb not to do sth = advise sb against doing 建议某人不要干
the teacher advised us not to read carelessly . = the teacher advised us against careless reading .
对比:the teacher advised our reading carefully . (动名词复合结构)
(3) advise that + 主语 + (should) do
 she advised that he spend his holidays in heinan .
对比:(误)sharon suggested me to ask dr yang for help .
(对)sharon advised me to ask dr yang for help .
(对)sharon suggested / advised that i should ask dr yang for help .
(对)sharon suggested / advised my asking dr yang for help .
(对)i was advised to ask dr yang for help by sharon .
(4) advice 是不可数名词,表达“一条建议”用:a piece / bit / word of advice 。
3. score (比赛的) 得分;(单复数相同)二十
the score at the end of the game was 5 to 4 against the visiting team . 比赛结果为 5 比 4 , 客队败北。
what's the score now ? 现在比分是多少 ?
〖点拨〗(1) scores of 许多,大批
the exhibition has scores of visitors every day .

(2) score 前有数词时,score 用单数,其后的 of 常省略。但在代词或者起定语作用的指示代词及物主掉次前的 of 不能省略。
three score of them are league members .
three score of those eggs are his .
she has two score (of) eggs . (这种情况下最好不用 of )
4. discuss 作及物动词是“讨论,议论”。名词形式是 discussion 。
i've something of great importance to discuss with you .
after careful discussion the two parties reached an agreement on this matter .
〖点拨〗(1) discuss 后直接接名词、疑问词 + to do ,不接 about / on 。但discussion 后可以接about 。
(错)we have discussed about the problem .
(对)we have discussed the problem .
(对)we have had a discussion about the problem .
(2) discuss sth with sb 和某人讨论……
we will discuss the changes of our school with them later .
(3) discuss freely 自由讨论,discuss fully / thoroughly 充分讨论,discuss keenly 激烈讨论,under discussion 在讨论中,have a long discussion about / on sth 对……进行长时间的讨论, a heated / hot discussion 热烈的讨论。
5. suggestion 建议
your suggestion is very helpful .
〖点拨〗(1) 含有suggestion 的主语从句、表语从句、同位语从句、定语从句中主句谓语用 should 型虚拟式。
we agree to his suggestion that the book (should) be published once more .
(2) suggestion 的搭配有:make a helpful / timely suggestion 作出有益(适时)的建议。act on / at one's suggestion = act on / at the suggestion of sb 按照某人的建议做。
(3) suggestion , advice 和 opinion
advice 多指根据自己的学识和经验提出来的供人参考的意见。suggestion 指为改进工作、解决问题而提出的建议,比 advice 委婉。opinion 是日常用语,指对某事的观点、想法。另外,advice 是不可数名词。
advice is seldom welcome . (谚语) 忠言逆耳。
in our opinion , these trees must be cut down at once .
we have decided to pay more attention to their suggestions .
单元词组思维运用
1. at the doctor's 在诊所
at the doctor's you can have your eyesight tested .
2. visit a doctor = see a doctor 看医生,看病,就诊
he had to visit a doctor because of his heart trouble .
3. a piece of bread 一块面包
4. a bit 有点儿(修饰形容词)
these apples are a bit green . 这些苹果有些生。
5. have a good rest 好好休息一下
6. in four hours' time 四小时后,四小时内
take two pills now and two more in fours' time .
they will arrive in two hours' time .
7. a diet of 一种……的食物
every person needs water and a diet of healthy foods .
8 . different kinds of 不同种类的
there are different kinds of moon cakes on mid-autumn day .
different kinds of book ( = different kinds of books = books of different kinds ) are on show in the book fair .

12. as much as 像……那样多;多达;到达……的程度。as much as 用于不可数的物体,而 as many as 则用于可数的物体。该结构还可以变化为:as much + 不可数名词 + as 或者 as many + 可数名词 + as 的形式。
here is a bottle of ink . you may use as much as you need .

14. be rich in 含有大量的;充满

二、学海导航
【学法指要】
单元句型思路明晰
1. even when + 从句
even when you are asleep , you are using energy . 甚至在你睡觉时,你也在消耗能量。
〖明晰〗even 作为副词放在由when引起的时间状语从句的前面起加强语气的作用。
even when it is in august , the weather there is very cold .
even when he was taking a holiday he was worried about his work .
2 . 主语 + be considered + to be + 主语补足语
the chinese diet is considered to be the healthiest in the world . 中国饮食被认为是世界上最健康的饮食。
〖明晰〗consider 做“认为”时可以带不定式的复合结构,即:主语 + consider + 宾语 + 不定式(主要是 to be 做宾语补足语)。如果将宾语变为主语,则 consider 用被动语态,原来作宾补的不定式便变成为主语补足语。注意:to be 常常被省略后成为:consider + 宾语 + 名词(或者形容词)。
he considered the task to be the most difficult one . → the task was considered to be the most difficult one by him .
we all consider his suggestion to be reasonable . → his suggestion is considered to be reasonable .
we consider this (to be) a useful book . → we consider this book useful .
单元难点疑点释疑
1 . when playing football or basketball , you might be using 400 calories an hour . 踢足球或者打篮球时,你每小时可能要消耗 400 卡能量。
〖释疑〗连词 when , while 引起的时间状语从句,如果从句中的主语与主句中的主语是同一人或物时,则可以省略主谓语,变成“when / while + ing”这中结构。
while he was doing the experiment , he noticed something strange . = while doing the experiment , he noticed something strange .
2 . in some parts of britain , one person in ten , by the age of thirty , has no teeth left . 在英国有些地方,十分之一的人年方三十,牙齿就掉光了。
〖释疑〗 one person in ten 即 one person in ten persons 的省略,其意思为“十个中有一个人”。与 one person in ten 类似的结构有:one person out of ten , one out of ten persons 。但是,ten to one 是“十有八九,很可能”。
two teachers in ten are against this plan .
three out of four people (= three fourths of the people ) went there to have a look .
it will rain tonight ten to one .
另外,left 为过去分词作定语修饰 teeth ,其意思是“剩余的”。
there is but one chance left . 只剩下一个机会。
3 . scores of people went there in the first few days after its opening . 开张的头几天,许许多多人到那家餐馆去就餐。
〖释疑〗after 为介词,其后的物主代词所有格 its 及名词 opening (开张,开幕;开放)构成介词短语作状语。in the first few days “在头几天里”,这里,the first 不是“第一”,当其后接复数名词时,意思是“头几个,第一批”。
i was one of the first people to visit the newly built factory .

答案:1 — 5 ddaab 6 — 10 cbbdd 11 — 15 dabad 16 — 20 cabab 21 — 25 ccccc
赏析:1 . d . 根据句意,需要填数词,the 后面跟序数词。2 . d。out 和 find 搭配是“发现、弄清”的意思。根据上一句话,他们当中的一个人去“the information center”,目的就是为了弄清火车开车的时间。3 . a。three 和 o'clock 连用是三点钟。4 . a。根据上文,他把火车延期这件事告诉了他的朋友。“delay”是延期之意,而 accident 是突发事件,tickets 是票,lateness 是“迟”的名词形式,均不合题意。5 . b。suggest 作“建议”解,后接从句,从句用虚拟语气“should + 动词原形”,should 可以省略。6 . c。so位于句首,引起倒装,go 与 off 连用是“去”之意;而 go on 是“继续”的意思;go in 是“进入状态”之意;go that 不是固定搭配,无词意。7 . b。他们三人进了酒巴,等了一会之后,故选 later。8 . b。track 是“铁轨”之意,与“rail”同义。stop 意为“停止”或“公共汽车站”;station 意为“火车站”;way 是“方法、道路”。此处说的是他们到了上火车的站台,也就是这列火车所在的铁轨处。9 . d。根据下文,三个人都 shouting , “wait ! come back!”,一定是火车离开了车站,故选out of。10 . d。因为火车已经开走,所以三个人只能跟在后面。11 . d。catch up with 为固定搭配,是“赶上”之意。12 . a。seize 作“紧抓”解;hold 意为“握住”;take意为“拿”;shake 意为“摇动”。由于他们迫切的心情,所以此刻一定要抓住。13 . b。pull 与 up 搭配是使他们能够跟住火车,而 pull on 是“戴上”的意思,pull off 是“脱下”的意思,pull in 是“车进站”的意思。14 . a。by 指“在这个时候”;till 表示时间时,指“到……时”;而 at this time 提“在此刻”;till 用于肯定句,与延续性动词连用;since 是“自从……”的意思,不合题意,因为三个人从追火车到此时是有一段时间的,故答案应选a。by。15 . d。stop doing something 是停止做某事,因为第三个人赶不上火车了,只好不跑了。stop to run 是停下来去跑的意思,不符合题意。16 . c。watch 后接不带 to 的动词不定式作宾语补足语。17 . a。空白处的动词和 wave 相并列,hear 指听见,而 listen to 指听的动作。c和d不合题意。故答案为a。18 . b。on his face 意为“在脸上”,指表情。19 . a。moment 片刻,minute 分钟。此时应该是过了片刻,而不是一分钟。故答案选a。20 . b。用 and 连接两个并列成分。21 . c。standing 是现在分词作定语,修饰 a man。其他三项不能作定语。22 . c。funny 是“滑稽、可爱”的意思。那个人看见两个人上了火车,第三个人没上去还大笑,便觉得可笑。23 . c。after 与 all 搭配,表示“毕竟”的意思。24 . c。so… 与 that 连用,表示“如此……以至于”。25 . c。see somebody off 意为“给某人送行”,see somebody out 意思是“把某人送到门口”,不合题意,see 与 away 搭配不成立,see 与 leave 搭配是不和题意的。

 coming in the church that their church was in need of             2 . _____
repairs . some of them said they would glad to give               3 . _____
five or ten dollars each in order that make the repairs .             4 . _____

old man in the back looked down toward the ceiling and       9 . _____
said“hit him again !”all the people were laughed .            10 . ____
答案:1. on → one。这里不是泛指星期天上午,而是具体的一个星期天的上午。 2. in → into 。3. would 后加 be 。因 glad 是形容词。4. that → to 。5. richer → richest 。因比较的范围是“in the town”。6. √。7. in → on 。8. 去out 。9. down → up 。10. 去掉 were 。此处是在场的人都笑了,而并非被嘲笑。

【心中有数】
单元语法发散思维
倒装句用法归纳
〖思维〗倒装的原因是语法结构的要求,或是为了或调。倒装句的类型有:
1 . 全部倒装 (即整个谓语结构放在主语前面)
(1) “there + be + 主语 + 其它”。本句型主要表示“有,存在;出现”等概念。
there is no desk in the room .
(2) “there (here , now , there) + come (go 或 be) + 主语”。这里的 there , now 等并不指具体的地点和时间;除 then 外,其余句子均用一般在时。
there comes the bus .
但如果这时的主语是人称代词时,主谓不倒装。如:here he comes .
(3) 直接引语的全部或一部分放在句地,其结构是“直接引语 + 谓语 + 主语”。如:
“let's go , ”said he .
(4) “方位词 + 不及物动词 + 主语”。其常用的动词有go , come 等。如:away went the boy .
但是如果主语是人你代词时,主谓也不倒装,可将上句改为:away he went .
(5) “地点状语 + 谓语 + 主语”。
in front of the house sat a small boy .
(6) “so + 助词 + 主语”。常用的助词有 be (是) ,have (有) ,助动词或情态动词。这一句型是对前面内容的肯定,表示“另一个 (或物) 也一样”。如:

本章链接:

发布时间:2017-05-05


 — he is a student .
— so am i .
— he likes skating .
— so does she .
但是,如果两句主语指的是同一个人或物时,主谓要用正常语序,即谓语要放在主语后。如:
son :“you promised to buy me a dictionary . ”
father :“so i did .”
(7) “neither (nor) ”+ 助词 + 主语”。这一句型与上一句型基本相同,只不过其意思是表示否定而已。如:i couldn't do it . neither could he .
(8) 为避免句子头重脚轻而将表语前置,其结构是:“表语 + 系动词(可加上助动词) + 主语 + 其它”。such would be our home in the future .
2 . 部分倒装 (即部分谓语放在主语之前)
(1) “否定词 + 谓语第一部分 + 主语 + 谓语第二部分 + 其它”。常用的否定词有never , seldom , little等;谓语第一部分通常是be , have , 助动词或情态动词。never could i forget the days .
如果没有前面提及的谓语第一部分,则需要加上do,或 does 或 did,且后面的动词要用原形。如:
little did she know that she was very ill .
(2) “only + 状语 + 谓语第一部分 + 主语 + 谓语第二部分”。但在这一句型中,主句倒装而从句不倒装。
only after being asked three times did he answer me .
only after he finished his task did i let him go .
(3) “no sooner (hardly) + had + 主语 + 过去分词 + than(when) + 从句”。这两句的意思是……就……”、“刚……就……”。
hardly had i sat down when the telephone rang .
(4) “not only + 谓语第一部分 + 主语 + 谓语第二部分 + 其它 + but also + 并列句(可以是省略的) 。”
not only was everything that he had taken away from him , but also his german citizenship .
(5) 虚拟语气中省略了“if”的条件句。其结构是:
“were (had或should) + 主语 + 谓语第二部分 + …… + 主语”。
had you worked harder , you would have passed the exam .
(6) as 引导的让步状语从句,其句型一般为“形容词(名语/动词) + as + 其它”。
pretty as the is (= though she is pretty) , she is not clever .
child as he is , he knows a lot .
try as he might , he would fail again .
3 . 作句型转换时的两点注意情况:
(1) 要分清两种倒装句 , 即全部倒装和部分倒装。
(2) 有的复合句是主句倒装,有的是从句倒装,要加以分清。如:only after his mother came back was he able to go to school . (主句倒装)
child as he is , he can solve the problem . (从句倒装)

  五、课堂作业:
  完成作业本一、二两题。

                第二课时
  一、复习导入。
  上节课,我们已学习了《数鸡》的第一段,现在谁来说说这一段主要讲什么?
  过渡:
  外婆家哪来这么多的鸡蛋呢?今天我们继续往下学习。
  二、研读第二段
  1、 现在,老师要请一位同学读一段,其它同学认真听。争取把这一段的内容都听懂了,待会老师要问大家一个问题,看谁能一口答出。你在听的时候,也可以猜猜老师可能会问什么?
  2、 抽生读这一段。
  3、 提问:
  你知道“我”在外婆家一共数了几次鸡?
  4、 生自己站起来回答,并说说自己的理由。
  5、 统一意见,明确理由。
  “……一有空就去数鸡。”看出“我”数了很多次鸡。
  6、再看看课文具体写了几次,分别用了什么方法数?
  (1) 自由读。
  (2) 交流。
  7、再找找,“我”还用了哪些方法数鸡?
  8、“我”数了这么多次鸡,数清了吗?
  你从哪里看出“我”还没数清?(找出多处理由)
  9、同学们,假如给你一个机会去数鸡,你会用什么方法去数鸡?你觉得你能数得清吗?
  不管是数得清,还是数不清,总之“我”是没数清,为什么“我”不写自己把鸡数清了呢?
  (突出鸡多)
  10、再找一找,这一段中还有哪些地方可以看出鸡多?
  生读书,找句子。
  交流:引导读出鸡多。
  (1)啊,满满一箩筐蛋:白的,粉红的。
  (2)院子里,公鸡、母鸡、白鸡……使我眼花潦乱
  (3)鸡听见这熟悉的声音一窝蜂似地拥来
  (4)并排十几个鸡筐里都有鸡在生蛋。
  ……
  并说明自己的理由。
  11、思考:
  外婆家哪来这么多的鸡?这和外婆家的生活有什么关系呢?外婆家能办起养鸡场*的是什么?
  三、研读第三段。
  1、 自由读这一段,思考:
  从这一段中,你有什么新的发现?
  2、交流:
  (1) 重点体会外婆的话。
  (2) 我的心理乐滋滋的仅仅是因为带回了三只小鸡和一篮鸡蛋吗?
  句中的省略号表示什么?
  用自己的话说说“我”心里为什么乐滋滋的。
  四、学习“学习提示”。
  1、 默读提示,思考:这一学习提示告诉我们什么?
  2、 交流:
  你从学习提示中读懂了什么?
  3、 小结:今后,我们要运用这样的方法去理解、掌握文章的中心思想。

   
  教后记:
  本课教学设计,我觉得比较满意的有两处。一处是我让学生来数鸡,看他们是否数得清。反过来讨论“我”为什么数不清,说明了什么。这样欲扬先抑,一方面调动了学生的积极性,另一方面也促进了学生对文本的理解。另一处是我的板书设计,从数鸡到一有空就去数,再到运用了各种各样的方法数,最后到数不清,得出结论“党的政策好,农村发展快”。条理清晰,易于学生读懂、理解。最后一条曲线连回来,说明了只有党的政策好,才能有外婆家这么多的鸡数,才能有农村人民生活的富足。
  不过,我也有个疑问。如果没有学习提示,学生是不是能领会到本课的中心思想呢?我看有困难。

一、教学目标
   1、知道什么是中心思想,初步学会领会文章的中心思想。
   2、学会本课的4个生字,理解10个词语的意思;了解多义词“生、开”在句子中的意思。
   3、能按事情发展顺序给课文分段,根据段落大意,并能借助课题概括课文的主要内容。
   4、懂得农村经济发展快,农民生活富裕,*党的经济政策好。
  二、教学过程:   (一)复习检查
    昨天,我们已学习了《数鸡》的第一段,现在请一位同学说说这一段主要讲什么?
    (板书:午饭丰盛竞是蛋的天下)
  (二)学习第二段
    引:外婆家哪来这么多的鸡蛋呢?今天我们继续往下学习,你就会明白。
   1、请打开课文25页,默读课文第二段,想一想:“我”在外婆家几次数鸡?每次怎么样?结果怎样?并填表。
    (出示投影,边读边做)
   2、交流填表内容,归纳板书:
     第一次 横数竖数 数不清
     几次数鸡  中间几次 大——小 数不清
     最后一次 放一只数一只     数不清
   3、看板书,说说“我”是怎样数鸡的?(要求语言简洁、流畅)
    (“我”一只一只数,从大数到小,从小数到大,放一只数一只,鸡多得这样数那样数都数不清。)
   4、“我”几次数鸡的方法各不相同,你认为哪种方法最多?<第三次>
   5、齐读第8节。
   6、那为什么结果都数不清呢?(鸡实在太多。)
   7、找一找,文章中还有哪些句子、词语明的暗的写鸡多?
   (1)啊,满满一箩筐蛋:白的,粉红的。<暗寓鸡多>
   (2)院子里,公鸡、母鸡、白鸡……使我眼花潦乱
    (a、这里的省略号表示什么?b、“眼花潦乱”什么意思?说明了什么?)
   (3)鸡听见这熟悉的声音一窝蜂似地拥来
    (“一窝蜂”什么意思?这是什么句?把什么比作什么?为什么这么比喻?)
   (4)并排十几个鸡筐里都有鸡在生蛋。
   8、读投影上的几句话
   9、外婆家哪来这么多的鸡?这和外婆家的生活有什么关系呢?外婆家能办起养鸡场*的是什么?
    (养鸡致富*党的政策,*勤劳。)
   10、小作者这样反反复复写外婆家鸡多,怎么也数不清,有一层没有明说的意思,你认为是什么?
    (外婆家养了那么多鸡,*鸡致富,生活有了改善,是党的政策引导农民发展生产,发家致富。)
   11、对!小作者就是怀着这样一份欣喜、好奇地要弄清楚外婆家到底养了多少鸡,并把数鸡当作一份乐趣,所以这一段的朗读应读出怎样的感情来呢?
    (带着喜悦的心情轻声自由朗读、齐读。)
  (三)学习的三段。
    引:那么这份心情在第三段中又是怎么体现的呢?
   1、指名朗读,其他学生思考:外婆的话说明了什么?
   2、投影出示课文最后一自然段的内容。
   (1)我的心理乐滋滋的仅仅是因为带回了三只小鸡和一篮鸡蛋吗?
   (2)句中的省略号表示什么?
   (3)“我为什么而心理乐滋滋的?”用因果句式把乐的原因说清楚。
   3、齐读最后一自然段,说说段意。
  (四)学习“学习提示”。
   1、默读提示,这一体示告诉我们什么?
    (阅读文章的要求什么是中心思想《数鸡》一文的中心思想)
   2、阅读文章的要求是什么?
   3、有关的词、句、段刚才已分析,请一位同学运用借助课题归纳主要内容的方法说说本文主要讲什么?
   4、还要领会中心思想,那么什么是中心思想呢?《数鸡》一文的中心思想是什么?
   5、学习提示的表述和我们课堂上说的意思一致的。现在请同学们在回顾一下,我们是怎样读懂作者的写作意图?
    (熟悉、理解内容,即分析字、词、句,理解内容→抓住重点段,联系课后习题,想想为什么反反复复地写鸡多,它表达出一种什么感情。)
   6、老师小结:今后,我们要运用这样的方法去理解、掌握文章的中心思想。
          午饭丰盛
                   第一次   横数竖数     数不清  改经
     4、数鸡  几次数鸡     中间几次   大→小    数不清  革济
                   最后一次  放一只,数一只 数不清  开发
          带回鸡、蛋 放展
