Bats are the only flying mammals (哺乳动物) in the world.They can’t see very well.It was long believed and still is in many places,that all bats are blind."Blind as a bat" is often heard.Yet they have no trouble in flying on the darkest nights and finding their way around very well.How can bats fly and see at night?They fly by radar.
The bat’s radar system works the same way as the one that ships and planes use.As a bat flies through the air,it makes a sound that is too high for our ears to hear.If the sounds hit things,they come back.The bat’s ears receive the messages.In this way they are able to tell where the things are.Bats go out to look for food at night.In the daytime they hang in some dark places.Some people have the bats as bad animals.In fact,they are useful animals

how to do a meaningful thing
As we all know that nobody can make the full use of time.we can just make the most of it to do a meaningful thing.
While how to do a meaningful thing is a question.First ,we should think over what you need so that the thing may be meaningful for us.Making a detailed plan is the most important step.Without it we may never do it successfully in a shorter time.Then,we can try your best to do it.Moreover,we can not only change your life but also make contributions to the society through making a meaningful thing.For example,we can appeal to everyone to do whatever we can to protect our environment.At the same time,we should reduce the harm to our motherland from the little thing in our dialy life.
In a word,a meaningful thing is that a thing that is worth the time and the energy that we spend in.

After a thorough search for a new employee,one candidate has risen to the top,and he has the look of a winner.Impeccable résumé.Extensive relevant experience.Great interpersonal skills.Plenty of energy and enthusiasm.Great new ideas he's eager to set in motion.
So you hire him.And it turns out to be one of the biggest mistakes you've ever made.
That glowing individual,so impressive sitting across the conference-room table,lies to customers and misrepresents your products.He can't satisfactorily explain the irregularities in his expense reports.He backstabs co-workers and takes credit for work he didn't do.
You have to let him go.But in his wake the questions remain:How were we so misled and so wrong?Why couldn't we have seen what kind of person we were really hiring?
The key to effectively interviewing for integrity is seeking multiple examples of behaviors and asking probing follow-up questions that reveal the thinking behind the behaviors described.While integrity-focused questions need be only a small part of the total interview,any ethical issues that arise must be explored fully so that the examples can be accurately evaluated and the best hiring decision reached.
It is important to incorporate integrity questions into an interview - and equally important to know when to ask those questions.Interviewers are wise to save sensitive ethical questions for late in the interview,after rapport has been developed.And,of course,as with all interview questions,once you have asked an ethical question,remember to listen and respond with empathy.
Empathy does not mean acceptance or agreement - it means understanding.You can be empathetic with a person who is telling you about an unethical behavior,without having to bend or sacrifice your own ethical standards,by reflecting the interviewee's feelings ("So you felt really good after the presentation," or "So you had second thoughts after the sales call").And by showing empathy,you can keep the individual talking,providing other examples of behavior that will foster your understanding.
The first step in an interviewing process to screen for honesty and integrity is for interviewers to ask the right questions.These questions need to be geared toward gathering information on past behaviors that illustrate whether a candidate's own ethical values are compatible with those of the organization.
Following is a list of questions,any of which could be incorporated into an interview to elicit examples of a candidate's past ethical behavior and to reveal insights about the candidate's honesty and integrity.While the list consists of 11 questions,most interview situations will dictate using only two or three such questions to obtain examples of past ethical behavior.
Also included are examples of good and questionable answers that candidates might give to these questions.The "rightness" or the "wrongness" of the answers is up to the interviewer's judgment.As such,it's important to train interviewers to follow up answers with more questions to pin down behavior and the thinking behind the behavior,to ask for additional examples,and to have a systematic integration of data so that multiple interpretations of the answers can be obtained and discussed.

Never think you will never be detected,when you want to tell a lie.The chances are,sooner or later,your lie witt be found out and it will then expose you to shame.
Telling a lie is morally wrong.Besides,there are many disadvantages lying in the way of a liar.First,he has to have a good memory,lest he contradicts at one time what he said in another.Second,he is always annoyed by his conscience,because he is in constant fear that his falsehood may be found out.Third,a liar is never trusted and respected by others.The result may be that his words,even when he speaks the truth,are not believed.Fourth and the last,once a person has told a lie,he cannot help telling another in order to conceal the first,and then a third and a fourth,until lying becomes ahabit.After that,he may say something untrue even when he wishes to speak the truth.
The disadvantages resulting from telling a lie are too many to be listed.The above are just some of the obvious ones.If you want to be free from these annoyances,if you want to be a trustworthy person,never tell a lie.

如果你把-9打成+9就悲剧了,希望没打错,那么的话,规律应该是:-3,-6,-12,-24,-48,-96,最后-99
所以1+2+3+……+99=4950
-3-6-12-24-48-96-99=-288
则 答案为 4950-288*2=4373（先消掉3,6,9……再减去3,6,9……）
如果不是+9是-9的话就是另当别论了

Mike came back from a morning jogging.


M: hi, Dan, what are u doing?
D: I am playing war craft.
M: Where is Tommy?
D: Shiiiii!
M:What? What's the matter?
D: Don't u see? He is still sleeping.
M: My goodness! I can't believe this! It’s almost nine. He got to get up now. Don't u remember we are required to make up a three people dialogue for tomorrow's oral class?
D: Yes, I do. You wake up Tommy and I will play one more round of war craft.
M: You'd better stop playing right now. We don't have much time to prepare this dialogue. Tommy! Tommy! Wake up! Time to wake up!
T:five more minutes, please.
Mike: No way, Jose. Time really flies.We still have a lot to do. Hurry up.
T: (Tommy sits up in his bed) Can I lie down two more minutes, please, just two more minutes? when Danny finishes his game, I will be fine.(Yawns) I don't know why I am so so sleepy. (Tommy lies down again.)
M: Guys! I am really angry now. Time waits for nobody. If you two don't stop what you are doing now, I will find somebody else to be my partners.
D and T: all right. All right. We listen to u.

M: That's more like it. We need will power.

General Introduction
I am a third year master major in automation at Shanghai Jiao Tong University,P.R.China.With tremendous interest in Industrial Engineering,I am writing to apply for acceptance into your Ph.D.graduate program.
Education background
In 1995,I entered the Nanjing University of Science & Technology (NUST) -- widely considered one of the China’s best engineering schools.During the following undergraduate study,my academic records kept distinguished among the whole department.I was granted First Class Prize every semester,and my overall GPA(89.5/100) ranked No.1 among 113 students.In 1999,I got the privilege to enter the graduate program waived of the admission test.I selected the Shanghai Jiao Tong University to continue my study for its best reputation on Combinatorial Optimization and Network Scheduling where my research interest lies.
At the period of my graduate study,my overall GPA(3.77/4.0) ranked top 5% in the department.In the second semester,I became teacher assistant that is given to talented and matured students only.This year,I won the Acer Scholarship as the one and only candidate in my department,which is the ultimate accolade for distinguished students endowed by my university.Presently,I am preparing my graduation thesis and trying for the honor of Excellent Graduation Thesis.
Research experience and academic activity
When a sophomore,I joined the Association of AI Enthusiast and began to narrow down my interest for my future research.In 1997,I participated in simulation tool development for the scheduling system in Prof.Wang’s lab.With the tool of OpenGL and Matlab,I designed a simulation program for transportation scheduling system.It is now widely used by different research groups in NUST.In 1998,I assumed and fulfilled a sewage analysis & dispose project for Nanjing sewage treatment plant.This was my first practice to convert a laboratory idea to a commercial product.
In 1999,I joined the distinguished Professor Yu-Geng Xis research group aiming at Network flow problem solving and Heuristic algorithm research.Soon I was engaged in the FuDan Gene Database Design.My duty was to pick up the useful information among different kinds of gene matching format.Through the comparison and analysis for many heuristic algorithms,I introduced an improved evolutionary algorithm -- Multi-population Genetic Algorithm.By dividing a whole population into several sub-populations,this improved algorithm can effectively prevent GA from local convergence and promote various evolutionary orientations.It proved more efficiently than SGA in experiments,too.In the second semester,I joined the workshop-scheduling research in Shanghai Heavy Duty Tyre plant.The scheduling was designed for the rubber-making process that covered not only discrete but also continuous circumstances.To make a balance point between optimization quality and time cost,I proposed a Dynamic Layered Scheduling method based on hybrid Petri Nets.The practical application showed that the average makespan was shortened by a large scale.I also publicized two papers in core journals with this idea.Recently,I am doing research in the Composite Predict of the Electrical Power system assisted with the technology of Data Mining for Bao Steel.I try to combine the Decision Tree with Receding Optimization to provide a new solution for the Composite Predictive Problem.This project is now under construction.
Besides,In July 2000,I got the opportunity to give a lecture in English in Asia Control Conference (ASCC) which is one of the top-level conferences among the world in the area of control and automation.In my senior year,I met Prof.Xiao-Song Lin,a visiting professor of mathematics from University of California-Riverside,I learned graph theory from him for my network research.These experiences all rapidly expanded my knowledge of English and the understanding of western culture.
I hope to study in depth
In retrospect,I find myself standing on a solid basis in both theory and experience,which has prepared me for the Ph.D.program.My future research interests include:Network Scheduling Problem,Heuristic Algorithm research (especially in GA and Neural network),Supply chain network research,Hybrid system performance analysis with Petri nets and Data Mining.
Please give my application materials a serious consideration.Thank you very much.

要是强翻得话可以说成 一生一世都爱我吧 省掉一些,谐音一些
自己瞎琢磨的,
你满意就给我说,我在那个上也回答下,不满意就算,也不多费采纳率
时间还早,看你的意思了

远近高低各不同

植树问题
1 非封闭线路上的植树问题主要可分为以下三种情形:
⑴如果在非封闭线路的两端都要植树,那么:
株数＝段数＋1＝全长÷株距－1
全长＝株距×(株数－1)
株距＝全长÷(株数－1)
⑵如果在非封闭线路的一端要植树,另一端不要植树,那么:
株数＝段数＝全长÷株距
全长＝株距×株数
株距＝全长÷株数
⑶如果在非封闭线路的两端都不要植树,那么:
株数＝段数－1＝全长÷株距－1
全长＝株距×(株数＋1)
株距＝全长÷(株数＋1)
2 封闭线路上的植树问题的数量关系如下
株数＝段数＝全长÷株距
全长＝株距×株数
株距＝全长÷株数
盈亏问题
(盈＋亏)÷两次分配量之差＝参加分配的份数
(大盈－小盈)÷两次分配量之差＝参加分配的份数
(大亏－小亏)÷两次分配量之差＝参加分配的份数
相遇问题
相遇路程＝速度和×相遇时间
相遇时间＝相遇路程÷速度和
速度和＝相遇路程÷相遇时间
追及问题
追及距离＝速度差×追及时间
追及时间＝追及距离÷速度差
速度差＝追及距离÷追及时间
流水问题
顺流速度＝静水速度＋水流速度
逆流速度＝静水速度－水流速度
静水速度＝(顺流速度＋逆流速度)÷2
水流速度＝(顺流速度－逆流速度)÷2
浓度问题
溶质的重量＋溶剂的重量＝溶液的重量
溶质的重量÷溶液的重量×100%＝浓度
溶液的重量×浓度＝溶质的重量
溶质的重量÷浓度＝溶液的重量
利润与折扣问题
利润＝售出价－成本
利润率＝利润÷成本×100%＝(售出价÷成本－1)×100%
涨跌金额＝本金×涨跌百分比
折扣＝实际售价÷原售价×100%(折扣＜1)
利息＝本金×利率×时间
税后利息＝本金×利率×时间×(1－20%)

无演员配音的只有原始母带 ,只有拍摄的电影公司和引进的公司才有
对白声音轨.音乐轨是分开的
电影视频的对白和音乐都是糅合在一起的
无法分开
所以你不可能单独消除声音而保留背景音效
还有种方法是这样的.
任何软件都不能做到完全的去处人声,特别是对欧美专业公司制作的专业唱片,歌声和伴奏都是混排的,所以根本没法处理.
但对于国内一些制作公司制作的唱片或音频文件可以某种程度上作一些处理,但只能由于家庭娱乐,可以用adobe AUDITION处理,也就是 cool edit pro的升级版
方法如下：
到如音频文件,然后“编辑”--“转换采样模式”,在弹出的对话框中选中“channels”（通道）选项中的mono(单声道)将左声道混合比和右声道混合比分别设置为100%和-100%可部分去除人声,这是最好的办法了

Dear Kathren:
I am so sorry that I can't have dinner with you on Sunday evening. Tony's mother will come to see us from Guangzhou. So we will go to the train station to pick her up on that day.
Thanks again for inviting me for dinner. Have a nice weekend.
Mary

原式={（x+1)/x}÷{x-(1+x²)/(2x)} = {（x+1)/x}÷{（2x²-1-x²)/2x} = {（x+1)/x}*{2x/(x²-1)}
= {(x+1)/x}*{2x/(x+1)(x-1)} = {1/x}*{2x/(x-1)} = 2/(x-1)

希望可以有所帮助

原式=2b/(a²-b²))-2b/(a²+b²)-(4b³(a⁴+b⁴)=
=2b2³b/(a⁴-b⁴)-(4b³(a⁴+b⁴)=0

不断努力
努力
再努力

2^99-2^100=2^99-2^99*x2=(1-2)x2^99= -2^99

因为bring 前面有does

1-2+3-4+5-6+...+95-96+97
=1+（3-2）+（5-4）+（7-6）+……+（95-94）+（97-96）
=1×49
=49

July 14th Wednesday rainy
Yesterday I came to the shopping center with my mother.We came to a place named “toward the air door”.I think many people know it.The night view is so beautiful that we all don’t want to back to home.I have a photo here.In the nine,we had to go back home.I didn’t wash my face before I went to bed,I’m too tired.
改个日期就行了.

公式很简单的：
球体=4πr^3/3
球面=4πr^2
（其中r是球的半径）
至于这公式推导的的过程不是初中程度的甚至也不是高中能掌握的,涉及到高等数学中的积分,是大学生的内容

In order to study well in the high school,I should do some ready.
Firstly, i think i should learn more English words in summer holiday.Because The more English
words
i can use,the more articles i can understand.Secondly,i can chat with foreign friends on the Net.Not only can i make friend with other countries friends ,but also i can improve my English .In fact ,learning English is very intersting.We can find that Enlish culture attracts us so much.GeneIn a word,i will do my best to make good use of internet in my summer holiday
