云云驾驶一辆宝马汽车从A地出发.先向东行驶15km,再向西行驶25km,然后又向东行驶20km,再又向西行驶40km,问

精神和物质的对立,是古希腊人的说法：他们认为肉眼能看到的东西是物质,除此之外都归于精神.比如人们呼出的空气,天空的风,能量等也算在精神里.
近代物理发现原子后,曾经把原子定义为“最小的物质单位”,在现代量子物理发现亚原子后,物质的定义再一次改变为：有静止质量的亚原子粒子属于物质,象光子、夸克等因为没有静止质量,所以不算物质.则按古希腊人把世界分为二元：不是物质就是精神的划分,光子等都算做精神了.
但,按量子物理,宇宙由“超弦”的波动构成,于是精神和物质都是超弦的不同振动组成的.也就是说,精神和物质都是同一种东西的不同表现.
按中国古代哲学认为：世界是心（精神）物（物质）一元的.中国古人对宇宙的这种认识,和现代物质对世界的认识,应该是一致的.
所以,强行划分精神和物质,

云像一个忙碌的画家
在天空中画出一幅又一幅的图画
云像一个贪玩的小捣乱
常常忘了回家
云像一位悠闲的诗人
在大地写下一首又一首的湿歌
云像一个羞涩的大姑娘
总是纯洁无瑕

明亮对云云说，《笔记》这首歌云云唱地真好，能教教明亮吗。。

Good afternoon,ladies and gentlemen.
How is everyone doing today?
I hope that everyone is well.
Every year,we have many holidays.
But to me,one holiday is the most special.
Can you guess what it is?
It happens once every year.
Everyone celebrates it.
The answer is New Year's Day.
New Year's Day is a time to remember.
We've lived another year of our lives.
It's time to think about what has happened.
We can remember time spent with family.
We can remember time spent with friends.
One year can hold a lot of good memories.
What things made us smile?
What things made us laugh?
We keep the good times in our hearts.
New Year's is also a time to forget.
Things don't always go our way.
Everyone has bad experiences.
But we need to learn to let go of our past.
the past can never be changed.
We need to learn our lessons and move on.
We should forget about bad things that happened.
But not forget what we learned from them.
The lessons we learn are valuable.
New Year's is a time of hope.
We've got another year ahead of us.
Just think about what's possible?
How will we improve this year?
What goals would we like to reach?
How many people could we help?
Another 365 days have been given to us.
We should be very thankful.
We should promise not to waste them.
Finally,New Year's is a time to celebrate!
it's time for New Year's parties!
It's time for family,friends,and fun!
We can watch the fireworks.
We can have a barbecue.
There's just so much to do!
New Year's is celebrated all over the world.
Everyone joins the excitement.
It's like one big party for the whole planet!
New year's is a most special time.
A whole year has passed.
And another year has come.
A new year is a very precious gift.
It can help make our dreams come true.
But what we do with it is up to us.
On New Year's,remember the good times.
Forget about the bad times.
A new year is waiting for us to enjoy!

希望侥幸成功得到封赏、先战后寻求取胜的办法,不是保全军队的好办法.起初,议论的人很多,要求转移的人也很多,时局还没到,我也认为可以.袁绍不用田丰的计谋,在官渡之战失败,已经获罪,检讨自己尚来不及.,

[and so forth] 如此,这样
1.周旋回转貌.
《吕氏春秋·圜道》：“云气西行,云云然.” 高诱 注：“云,运也,周旋运布,肤寸而合,西行则雨也.”
2.芸芸.众貌；盛貌.
《庄子·在宥》：“万物云云,各复其根.” 成玄英 疏：“云云,众多也.” 南朝 梁 沉约 《述僧中食论》：“万事云云,皆三者之枝叶耳.” 唐 陈子昂 《麈尾赋》：“天之浩浩兮物亦云云,性命变化兮如丝之棼.” 明 李东阳 《桂岩书院题》诗：“冠裳皆秩秩,礼乐漫云云.”
3.犹纭纭.纷纭；纷纷(多用于形容言语、议论多而杂).
汉 仲长统 《昌言·损益》：“为之以无为,事之以无事,何子言之云云也?” 唐 薛逢 《题独孤处士村居》诗：“何如一被风尘染,到老云云相是非.” 元 张可久 《寨儿令·春思》曲：“阑干旧时无限春,笑语云云,图画真真.” 清 李渔 《蜃中楼·耳卜》：“多应此处有声闻,洗耳听云云.”
4.犹言如此,这样.
汉 阮瑀 《为曹公作书与孙权》：“闻 荆州 诸将,并得降者,皆言 交州 为君所执,豫章 拒命,不承执事,疫旱并行,人兵减省,各求进军.其言云云,孤闻此言,未以为悦.” 唐 孟云卿 《伤时》诗之一：“岂伊逢世运,天道亮云云.” 严复 《原强续篇》：“致吾国君臣上下,谓经武之事,不外云云.”
5.一般多用为表示有所省略之词.
《汉书·汲黯传》：“上方招文学儒者,上曰吾欲云云.” 颜师古 注：“云云,犹言如此如此也,史畧其辞耳.”《孔子家语·好生》：“ 孔子 为 鲁 司寇,断狱皆进众议者而问之曰：‘子以为奚若?某以为何若?’皆曰云云.如是,然后夫子曰：‘当从某子几是.’” 唐 韩愈 《石鼎联句》诗序：“次传於 喜 ,喜 踊跃,即缀其下云云,道士哑然笑曰：‘子诗如是而已.’”
6.谓等等,之类.
鲁迅 《且介亭杂文·附记》：“只有不准说‘言行一致’云云,也许莫明其妙,现在我应该指明,这是因为又触犯了‘第三种人’了.” 孙犁 《金梅＜文海求珠集＞序》：“目前有一种流行的说法：有些文艺评论所以写不好,是因为作者没有创作实践云云.”
7.助词.用于句末,无义.
《红楼梦》第一回：“作者自云曾历过一番梦幻之后,故将真事隐去,而借‘通灵’说此《石头记》一书也,故曰‘甄士隐’云云.”
8.山名.
泰山 下的小山,在 山东省 泰安市 东南.《管子·封禅》：“昔 无怀氏 封 泰山 ,禅 云云 .” 尹知章 注：“ 云云山 在 梁父 东.” 南朝 梁简文帝 《南郊颂》序：“方当巡 云云 之礼,启 亭亭 之业.”

然后对应项相加
发现每个对应项相加为n+1 也就是首尾相加 一共是n项 当然最后还要除以2

一个莺在空中两朵云云打一成语
答案是【草长莺飞】
莺：黄鹂.形容江南暮春的景色.

设婷婷卖了x元,则云云卖了28.8-x元
x:(28.8-x)=4:5
内项积等于外项积
5x=4(28.8-x)
5x=115.2-4x
9x=115.2
x=12.8
所以婷婷卖了12.8元

云云买笔比小敏买橡皮多花了19-1=18元,所以两个人一共有18×4=72元.
现在两个人倍数关系是1倍和3倍,所以72÷3=24.或者是72×1/3=24.
具体算式：（19-1）×4=72.元 72÷3=24元.
验算一下是正确的.
24÷4=6（元）【小敏原来是6元】
小敏卖完橡皮还有6-1=5元.
云云买了水彩后是24-19=5元
5元=5元

以下是非常准确的翻译,我曾在国外做过国学研究,所以有国学经典著作的英译本：
This is the openingsection; this the first chapter.Subsequent to the visions of a dream which hehad,on some previous occasion,experienced,the writer personally relates,hedesignedly concealed the true circumstances,and borrowed the attributes ofperception and spirituality to relate this story of the Record of the Stone.With this purpose,he made use of such designations as Chen Shih-yin (truthunder the garb of fiction) and the like.What are,however,the eventsrecordedin this work?Who are the dramatis personae?
Wearied with the drudgery experienced of late in the world,the author speaking for himself,goes on to explain,with the lack of success which attended every single concern,I suddenly bethought myself of the womankind of past ages.Passing one by one under a minute scrutiny,I felt that in action and in lore,one and all were far above me; that in spite of the majesty of my manliness,I could not,in point of fact,compare with these characters of the gentle sex.And my shame forsooth then knew no bounds; while regret,on the other hand,was of no avail,as there was not even a remote possibility of a day of remedy.On this very day it was that I became desirous to compile,in a connected form,for publication throughout the world,with a view to (universal) information,how that I bear inexorable and manifold retribution; inasmuch as what time,by the sustenance of the benevolence of Heaven,and the virtue of my ancestors,my apparel was rich and fine,and as what days my fare was savory and sumptuous,I disregarded the bounty of education and nurture of father and mother,and paid no heed to the virtue of precept and injunction of teachers and friends,with the result that I incurred the punishment,of failure recently in the least trifle,and the reckless waste of half my lifetime.There have been meanwhile,generation after generation,those in the inner chambers,the whole mass of whom could not,on any account,be,through my influence,allowed to fall into extinction,in order that I,unfilial as I have been,may have the means to screen my own shortcomings.Hence it is that the thatched shed,with bamboo mat windows,the bed of tow and the stove of brick,which are at present my share,are not sufficient to deter me from carrying out the fixed purpose of my mind.And could I,furthermore,confront the morning breeze,the evening moon,the willows by the steps and the flowers in the courtyard,methinks these would moisten to a greater degree my mortal pen with ink; but though I lack culture and erudition,what harm is there,however,in employing fiction and unrecondite language to give utterance to the merits of these characters?And were I also able to induce the inmates of the inner chamber to understand and diffuse them,could I besides break the weariness of even so much as a single moment,or could I open the eyes of my contemporaries,will it not forsooth prove a boon?This consideration has led to the usage of such names as Chia Yü-ts'un and other similar appellations.

译文：
贾岛初次去京城考试.一天他骑着毛驴赋诗,吟得“鸟宿池边树,僧敲月下门”之句.开始的时候想用推字 想想又觉得敲字好.不能决定用什么好,于是反复吟咏,并且用手做推与敲的姿势.韩愈当时是吏部权兆尹.贾岛不知不觉的冲撞到仪仗队的第三节,被侍从押到韩愈身前.贾岛于是对韩愈讲了自己作诗的经过.韩愈在马上停了很久,对贾岛说:敲字比较好.于是与贾岛一起回到了自己的府第.在一起谈论诗歌,两人最后成了好朋友.

Remember the day we meet?The white clouds drift with,so beautiful.

不奢求时光停留,只愿你能记住,此刻我眼中的你.
仅此诗献给我最爱的云云.

没听过,是不是记错了啊!我只记得有个“不知云与我俱东",为了不让你的分百给我,不知云与我俱东意思如下：
飞花两岸照船红,百里榆堤半日风.卧看满天云不动,不知云与我俱东
陈与义（一○九○～一一三八）字去非,自号简斋,洛阳人,有“简斋集”.
这是诗人在河南行舟襄邑道中的真实感受.船顺水而下,趁着顺风,百里路程只走了半天,水速是惊人的.榆堤两岸的景物,应似飞掠而过,此诗虽未写出,可由想象而得.然而,诗人注意的却是船上看云的感受：躺在船上看那满天云彩,一动不动,船行百里,竟没有觉察到云彩和乘船人都在向东.船上观景,看天上云彩是一种感受,看两岸花木又是另一番感受.感受的不同,反映了主体与客体的距离的不同：花木在近处,看去似飞动；白云太离远,观者未觉动.可是,同一个陈与义在另一种场合下看那天上的云,却又象跟着归去的诗人在一起行走：
还有个“不知所云”：
云：说.不知道说得是些么.形容说话内容混乱,无法理解.
【出自】：三国·蜀·诸葛亮《出师表》：“临表涕泣,不知所云.”
【示例】：这篇文章逻辑性太差,使人看了～.
【近义词】：不得要领、语无伦次、吞吞吐吐

解题思路：因为聪聪和云云共21岁，聪聪和明明共16岁，云云和明明共19岁，所以（21+16+19）÷2=28岁，表示3个孩子的年龄和，28-21就是明明的年龄，28-16就是云云的年龄，28-19就是聪聪的年龄，据此解答即可．

（21+16+19）÷2-21
=28-21
=7（岁）
（21+16+19）÷2-16
=28-16
=12（岁）
（21+16+19）÷2-19
=28-19
=9（岁）
答：明明7岁，云云12岁，聪聪9岁．

点评：
本题考点： 简单的等量代换问题．

考点点评： 解答本题的关键是：（21+16+19）÷2表示3个孩子的年龄和，然后分别减去任意两个人的年龄和就是第三个人的年龄．

你说的其实是理论和实际,主观和客观的关系问题.任何实际都不可能百分百符合理论,理论和实际,主观和客观之际反映于被反映的关系是有偏差的.因为任何对客观世界的观测都必须借助一定手段和方法,得到的结果必须经由人的感官加上思维的推理判断而得到认识和结论,这期间的每一个环节都存在误差.无理数是真实存在的,并且是无限多且比有理数致密得多.但人们没法精确计算和写出无理数.

云今年是:64/(9-1)=8岁
爷爷今年是:8*9=72岁.
等量关系是:二人年龄差64=爷爷的年龄-云的年龄.
