he MonkeyAnd The Crocodile

One day a
little monkey was playing in a tall tree by the river .A crocodile was swimming
slowly near the bank with her baby .She looked around for some food .Suddenly
she saw the monkey. “Aha ,there’s my meal ,”she thought .She then turned to her son , “Do you love me
,Son?

“Why ,of
course ,Mum !” the baby crocodile said . “well then ,you catch that monkey and
give me his heart to eat .” “But how can I?” the baby crocodile asked,

“Monkeyscan’t swim , and I can’t climb trees.”

“You needn’tclimb the tree.” His mother said. “Use your head , then you’ll find a way.”

The baby
crocodile thought hard. Then he had an idea. He swam near the tree and shouted,
“Hey, Monkey! Would you like some bananas?”

“Bananas!Mm! I love them,” said the monkey “But where are they?”

“On the
other side of the river. There are some banana trees there, and they have lots
of bananas on them. I’ll take you there on my back.”

“Good,” themonkey came down and jumped onto the crocodile’s back.

Soon they
were in the middle of the river .Suddenly the crocodile went down under the
water .When he came up again ,the monkey was all wet . “Don’t do that !” the
monkey cried . “Don’t do that again ! I can’t swim ,you know .” “I know ,but I
have to ,”answered the crocodile . “My mother wants to eat your heart.” The
little monkey was clever . “Why didn’t you tell me earlier ?”he asked . “My
heart isn’t here with me .I left it in that tree over there .”

“Then we’ll
have to go back for it .Mother doesn’t want you without your heart .”The
crocodile turned and swam back to the bank .

Soon they
reached the bank .The monkey jumped off the crocodile at once , picked up a big
stone and quickly climbed up the tree .The crocodile waited for the monkey to
come down again .He waited and waited .As he was waiting ,he suddenly heard a
voice from above : “Hey ,Crocodile !” The crocodile looked up .The monkey was
hanging from the tree by his tail and laughing . “Here’s my heart .Come up and
get it .Don’t keep your mother waiting ...You can’t come up ? Well ,catch!”

With thesewords ,he threw the big stone at the crocodile .
美国的很经典的寓言故事,虽然长了点.

1、子曰：“学而时习之,不亦说乎?有朋自远方来,不亦乐乎?人不知而不悦,不亦君子乎?”(《学而》)
学习需要不断复习才能掌握.学了知识,按时复习,这是愉快的事.这里既有学习方法,也有学习态度.朋,这里指志同道合的人.有志同道合的人从远方来,在一起探讨问题,是一种乐趣.
人家不了解,我却不怨恨,是君子的风格.这是讲个人修养问题.
2、子曰：“温故而知新,可以为师矣.”(《为政》)
复习旧的知识,能够从中有新的体会或发现.这样,就可以做老师了.
3、子曰：“学而不思则闰；思而不学则殆.”(《为政》)
只读书而不肯动脑筋思考,就会感到迷惑；只是一味空想而不肯读书,就会有疑惑.
这里阐述了学习和思考的辩证关系,也是讲学习方法的.

你是专门搞竞赛的？这道你行么。。？略难

别人是你的一面镜子
old friends are like zhe.The first time you meet someone, in the first moment you form an impression in
　　your mind of that person. Your reactions to other people, however, are really
　　just barometers for how you perceive yourself. Your reactions to others say
　　more about you than they do about others. You cannot really love or hate about
　　yourself. We are usually drawn to those who are most like us and tend to
　　dislike those who display those aspects of ourselves that we dislike.
　　
Therefore, you can allow others to be the mirror to illuminate more clearly
　　your own feelings of self-worth. Conversely, you can view the people you judge
　　negatively as mirrors to show you what you are not accepting about yourself.
　　
To coexist peacefully with others, you will need to learn tolerance. A big
　　challenge is to shift your perspective radically from judgment of other to a
　　lifelong exploration of yourself. Your task is to assess all the decisions,
　　judgments you make onto others and to begin to view them as clues to how you
　　can heal yourself and become whole.
　　
I recently has a business lunch with a man who displayed objectionable table
　　manners. My first reaction was to judge him as offensive and his table manners
　　as disgusting. When I noticed that I was judging him, I stopped and asked
　　When you approach life in this manner, those with whom you have the greatest
　　grievances as well as those you admire and love can be seen as mirrors,
　　guiding your to discover parts of yourself that you reject and to embrace your
　　greatest quality.

图书大厦有卖的.

化学的理论解释当然是基于实践认识了 人们测得的有关于CO2的数据支持C原子时SP杂化的
那么没有数据的情况下如何得出他是SP杂化呢 我们有一个经验公式 那就是
参与杂化轨道数=（中心原子所在主族序数+周围原子的修正+电荷的修正+周围原子作为中心原子的修正） 除以2
中心原子所在主族序数不用说很简单 O就是6 N就是5 碘原子就是7 稀有气体原子就是8
周围原子的修正：卤素为1 氧族元素为0 氮族元素为-1 H为1
电荷的修正：正1价就-1 负1价就+1
周围原子作为中心原子的修正：如果考察的周围原子除了和中心原子相连之外 还和其他元素相连 那么就-1
得到的数如果为小数 那么采用进一法
最后得到的结果如果为
2 就是SP杂化
3 ----------SP2
4----------SP3
5----------SP3D
6----------SP3D2
7-----------SP3D3
这个方法只适用于中心元素为主族元素的 粒子
另外参与杂化轨道数=（中心原子所在主族序数+周围原子的修正+电荷的修正+周围原子作为中心原子的修正） 除以2 这个公式一般的教材上没有最后一项 周围原子作为中心原子的修正 这使得这个公式的应用很不广泛 分子稍微以复杂就不适用了
我在高中的时候听过某大学化学院主任的讲课 他基于他的认识加上了周围原子作为中心原子的修正这一项 使得这个公式基本上可以适用于中学 中学竞赛 本科阶段可以见到的绝大多数分子了

国内外:
1. at home and abroad
2. both here and abroad
3. home and abroad

例句与用法:
1. 西方应该毫无保留地支持苏联使其成功吗?或者西方的经济支援是否应视苏联在国内外政治行为来决定?西方政客们权衡他们的选择,可是这项选择是错误的.西方对苏联的制衡并不存在.
Should the West root unreservedly for Soviet success? Or should Western economic support turn on Soviet political behavior at home and abroad? Western politicians weight the choice, but it's a false choice: the leverage doesn't exist.

5.呼应前文,同时用简单的道具深刻的表现出.技艺高超
总之就是离不开“技艺高超”啦.不过各小题回答时注意改一下句式...不要太雷同了..
关键还是要润色...俗称扩句

在课堂上我们应该做到以下几点：1.静听.上课认真听讲,做好笔记,无论听、说、读、写都要使自己始终活跃..2.积极参与.英语是实践性强的学科,要大胆地练习,敢说、敢读,积极回答老师提出的问题.课堂上积极发言对我们是大有裨益的,每一次的积极发言都是一次听说训练,可以使我们集中精力,对较难或者模糊不清的问题有一个明确的答案.经常举手发言也可以让老师加深对自己的印象.课堂上的听讲至关重要,老师在讲到重点时总有自己的语言或者体态特点,我们要善于观察和把握.3.勤动笔.把教师的重点及时迅速记在课堂记录本上,不过要处理好听课和记笔记的关系,不能顾此失彼.4.多开口.对于自己课堂不清楚的地方,下课后一定要及时询问老师,把问题解决在当天,不要顾及所谓的面子而不懂装懂,否则漏洞越来越多,最后造成英语成绩的不断滑坡.
学好外语还要记住以下几个原则
1．学习不中断,哪怕每天挤出10分钟也可以,早晨则是大好时机.
2．学厌了可变换一下学习方式或形式.
3．不要脱离下下文孤立地死记硬背.
4．随时记下并背熟那些常用的句型.
5．要敢于说外语,不要怕出错误,要请别人纠正,不要难为情,更不要泄气.
6．要坚信自己一定能够达到目的,坚信自己有坚强的毅力和学好外语的才能

1、 两个男孩各骑一辆自行车,从相距2O英里（1英里合1.6093千米）的两个地方,开始沿直线相向骑行.在他们起步的那一瞬间,一辆自行车车把上的一只苍蝇,开始向另一辆自行车径直飞去.它一到达另一辆自行车车把,就立即转向往回飞行.这只苍蝇如此往返,在两辆自行车的车把之间来回飞行,直到两辆自行车相遇为止.如果每辆自行车都以每小时1O英里的等速前进,苍蝇以每小时15英里的等速飞行,那么,苍蝇总共飞行了多少英里?
答案
每辆自行车运动的速度是每小时10英里,两者将在1小时后相遇于2O英里距离的中点.苍蝇飞行的速度是每小时15英里,因此在1小时中,它总共飞行了15英里.
许多人试图用复杂的方法求解这道题目.他们计算苍蝇在两辆自行车车把之间的第一次路程,然后是返回的路程,依此类推,算出那些越来越短的路程.但这将涉及所谓无穷级数求和,这是非常复杂的高等数学.据说,在一次鸡尾酒会上,有人向约翰?冯·诺伊曼（John von Neumann, 1903～1957,20世纪最伟大的数学家之一.）提出这个问题,他思索片刻便给出正确答案.提问者显得有点沮丧,他解释说,绝大多数数学家总是忽略能解决这个问题的简单方法,而去采用无穷级数求和的复杂方法.
冯·诺伊曼脸上露出惊奇的神色.“可是,我用的是无穷级数求和的方法.”他解释道

2、 有位渔夫,头戴一顶大草帽,坐在划艇上在一条河中钓鱼.河水的流动速度是每小时3英里,他的划艇以同样的速度顺流而下.“我得向上游划行几英里,”他自言自语道,“这里的鱼儿不愿上钩!”
正当他开始向上游划行的时候,一阵风把他的草帽吹落到船旁的水中.但是,我们这位渔夫并没有注意到他的草帽丢了,仍然向上游划行.直到他划行到船与草帽相距5英里的时候,他才发觉这一点.于是他立即掉转船头,向下游划去,终于追上了他那顶在水中漂流的草帽.
在静水中,渔夫划行的速度总是每小时5英里.在他向上游或下游划行时,一直保持这个速度不变.当然,这并不是他相对于河岸的速度.例如,当他以每小时5英里的速度向上游划行时,河水将以每小时3英里的速度把他向下游拖去,因此,他相对于河岸的速度仅是每小时2英里；当他向下游划行时,他的划行速度与河水的流动速度将共同作用,使得他相对于河岸的速度为每小时8英里.
如果渔夫是在下午2时丢失草帽的,那么他找回草帽是在什么时候?
答案
由于河水的流动速度对划艇和草帽产生同样的影响,所以在求解这道趣题的时候可以对河水的流动速度完全不予考虑.虽然是河水在流动而河岸保持不动,但是我们可以设想是河水完全静止而河岸在移动.就我们所关心的划艇与草帽来说,这种设想和上述情况毫无无差别.
既然渔夫离开草帽后划行了5英里,那么,他当然是又向回划行了5英里,回到草帽那儿.因此,相对于河水来说,他总共划行了10英里.渔夫相对于河水的划行速度为每小时5英里,所以他一定是总共花了2小时划完这10英里.于是,他在下午4时找回了他那顶落水的草帽.
这种情况同计算地球表面上物体的速度和距离的情况相类似.地球虽然旋转着穿越太空,但是这种运动对它表面上的一切物体产生同样的效应,因此对于绝大多数速度和距离的问题,地球的这种运动可以完全不予考虑．
3、 一架飞机从A城飞往B城,然后返回A城.在无风的情况下,它整个往返飞行的平均地速（相对于地面的速度）为每小时100英里.假设沿着从A城到B城的方向笔直地刮着一股持续的大风.如果在飞机往返飞行的整个过程中发动机的速度同往常完全一样,这股风将对飞机往返飞行的平均地速有何影响?
怀特先生论证道：“这股风根本不会影响平均地速.在飞机从A城飞往B城的过程中,大风将加快飞机的速度,但在返回的过程中大风将以相等的数量减缓飞机的速度.”“这似乎言之有理,”布朗先生表示赞同,“但是,假如风速是每小时l00英里.飞机将以每小时200英里的速度从A城飞往B城,但它返回时的速度将是零!飞机根本不能飞回来!”你能解释这似乎矛盾的现象吗?
答案
怀特先生说,这股风在一个方向上给飞机速度的增加量等于在另一个方向上给飞机速度的减少量.这是对的.但是,他说这股风对飞机整个往返飞行的平均地速不发生影响,这就错了.
怀特先生的失误在于：他没有考虑飞机分别在这两种速度下所用的时间.
逆风的回程飞行所用的时间,要比顺风的去程飞行所用的时间长得多.其结果是,地速被减缓了的飞行过程要花费更多的时间,因而往返飞行的平均地速要低于无风时的情况.
风越大,平均地速降低得越厉害.当风速等于或超过飞机的速度时,往返飞行的平均地速变为零,因为飞机不能往回飞了.
4、 《孙子算经》是唐初作为“算学”教科书的著名的《算经十书》之一,共三卷,上卷叙述算筹记数的制度和乘除法则,中卷举例说明筹算分数法和开平方法,都是了解中国古代筹算的重要资料.下卷收集了一些算术难题,“鸡兔同笼”问题是其中之一.原题如下： 令有雉（鸡）兔同笼,上有三十五头,下有九十四足.
问雄、兔各几何?
原书的解法是；设头数是a,足数是b.则b／2－a是兔数,a－（b／2－a）是雉数.这个解法确实是奇妙的.原书在解这个问题时,很可能是采用了方程的方法.
设x为雉数,y为兔数,则有
x＋y＝b, 2x＋4y＝a
解之得
y＝b／2－a,
x＝a－（b／2－a）
根据这组公式很容易得出原题的答案：兔12只,雉22只.
5、我们大家一起来试营一家有80间套房的旅馆,看看知识如何转化为财富.
经调查得知,若我们把每日租金定价为160元,则可客满；而租金每涨20元,就会失去3位客人. 每间住了人的客房每日所需服务、维修等项支出共计40元.
问题：我们该如何定价才能赚最多的钱?
答案：日租金360元.
虽然比客满价高出200元,因此失去30位客人,但余下的50位客人还是能给我们带来360*50=18000元的收入； 扣除50间房的支出40*50=2000元,每日净赚16000元.而客满时净利润只有160*80-40*80=9600元.
当然,所谓“经调查得知”的行情实乃本人杜撰,据此入市,风险自担.
6 数学家维纳的年龄,全题如下： 我今年岁数的立方是个四位数,岁数的四次方是个六位数,这两个数,刚好把十个数字0、1、2、3、4、5、6、7、8、9全都用上了,维纳的年龄是多少? 咋一看,这道题很难,其实不然.设维纳的年龄是x,首先岁数的立方是四位数,这确定了一个范围.10的立方是1000,20的立方是8000,21的立方是9261,是四位数；22的立方是10648；所以10=

(2)_______ his "free' hour from two to three in the afternoon, Mr Wang (3)________ meet with parents, check students' homework and (4)_______ many other things. So Mr Wang works hard from the moment he gets to school early in the morning until he leaves for home late in the afternoon, and his "free' hour is not free at all.
In his English lesson, Mr Wang sometimes teaches poems. He likes poems very much, and he likes Li Bai's poems (5)________ of all.
In his fifth class today, Mr Wang taught a poem. He wrote the poem on the blackboard and read it. As soon as he finished (6)_______ the poem, the students began to ask questions. He answered all the questions. Then he asked his students to talk about the poem. No one wanted to (7)______ when the bell rang.
(8)_______ home, Mr Wang thought about the fifth class. He was happy about what he did as a teacher. Every student in his class (9)________ the poem. When they started to talk, they forgot about the time. He did not have to make them (10)________. He only had to answer their questions and help them understand the poem.
( )1. A. was B. being C. to be D. be

( )10.A. learning B. to learn C. learn D. learned
题解与分析：
这是一篇记叙文,文章主要介绍了Mr Wang是如何热爱教师这份职业的.
1.C. 表示“想要做某事”应用句式want to do….
2.A. 这里所说的下午两点至三点是一个时间段,所以用in比较合理,因为介词可以表示在某一时间段内 ；at只表示时间点；to 的意思是“到,对于”；on表示“在某一固定的时间段或在某一星期”.
3.A. 根据词语的意思和和搭配形式,这里用has to 最佳.
4.C. 表示“照看,照顾”应用短语take care of 或look after.
5.D. 这句话的意思是“在所有的诗当中,他最喜欢李白的诗.”这里的介词of短语多与最高级连用.
6.A. 动词enjoy, finish, mind, spend之后应该加名词,代词,动名词做宾语.
7.根据这一段的意思,由于同学们正在讨论诗歌,所以即使是下课了,他们也没有停下来.
8.C. by the way 的意思是“顺便说”,on one's way 的意思是“在……的路上”,in the way 的意思是“用这种方式”,to one's way 是错误搭配.根据这些区别,这里用on his way 最佳.
9.A. 在下午上课时,所有的学生都喜欢诗歌,这从上文的意思可知.
10.C. 动词make之后应加不带to 的不定式做宾语补足语.

（2）D为BC中点时,四边形CDEF是平行四边形,∠DEF=30°.
证明：因为三角形ABC为等边,D为BC中点,则AD垂直于BC,即∠ADB=90°,又因三角形ADE为等边,则∠ADE=60°,则∠EDB=30°.因为BF=CD,所以F也为AB中点,CF为∠ACB角平分线,则∠BCF=30°,即∠EDB=∠BCF,DE//CF.又因CF=AD=DE,则四边形CDEF是平行四边形.平行四边形对角相等,则∠DEF=∠BCF=30°.
