Generally, knowledge gained from books is theoretical, that gained from experience is practical. It is difficult to answer which is more important to we people. It depends on the phases and events of our learning.
Knowledge learned from books is instructive which perhaps cannot learn directly from experience. We often hear thunders and see lightning in the sky, and we can easily find that lightning will be seen sooner than sound will be heard. According to our experience alone, we cannot tell why it had happened. But when we learn some physics in textbooks, we will find the answer clearly that because light travels faster than sound does, it takes less time for light to travel the same distance than for sound. Therefore, book knowledge can inform us some useful theories that can give us general ideas and help us understand the real phenomenon better.
In turn, practice knowledge check out the theories gained from books. There is an old Chinese saying that practice is the only criterion of inspecting the truth. So not all knowledge from books is credible, even false. When Aristotle wrote in his transcripts that the earth is the center of our planets, no one doubts this for centuries. However, when Galileo read about it, he did not suspect it at first, but when he made some observation and research, he found it is not the truth. Then comes the new theory—Sun center theory.
Soccer is the most popular sport in the world.
For those of you who are unfamiliar with the game I would like to give a brief introduction. 2 teams of 11 players compete on a soccer field at once. They can only touch the ball with their feet, head and chest. If they use their hands, the ball is given to the other team. Only the goalie can use hands. The objective is for each team to score on the opposing team's goal.
In 2004, the president of the International Confederation of Association Football, or FIFA for short, confirmed that soccer originated from China during the Warring States Period in 476-221 B.C. However, even though they followed the no-hands rule it was still very different from the soccer we know and love today.
Soccer changed and developed over the next centuries as it traveled through different countries around the world.
Modern day soccer started in England about 200 years ago. In May 21 1904, FIFA was established in Paris. From 1930, a World Cup would be held every 4 years.
Soccer is already a sport that we need in our life. There are about 800 thousand teams that usually play in matches. There are about 40 million players that signed up. There are a 100 thousand professional players.
As I mentioned before, traditionally, soccer matches have consisted of 11 players; however, now other competitive options are available including, five on five, seven on seven, and even beach soccer.
Soccer is really a sport that can be enjoyed by people of all ages and ability. I have loved playing for more than half of my life and I know that if you start today you will too.
Easter is the Christian commemoration of the resurrection of Jesus as a religious holiday. Over the past year the spring equinox, the first full moon of the first Sunday after Easter. Church of Christ in the early years of the date of Easter, there have been controversial, causing momentary confusion, until 325 AD, the priests of the Church of the meeting before deciding on a day to celebrate the unification of the Easter.
There are a lot of the traditional Easter celebration, Easter egg is a symbol of the most typical. In ancient times the eggs are often seen as more children and grandchildren and a symbol of resurrection, because it breeds new life. Later, Christians also gives new meaning to the egg that it is a symbol of the tomb of Jesus, the life of the future is born from it and get rid of. Easter eggs are often dyed red to represent the crucifixion of Jesus when the blood flow, but also a symbol of happiness after the resurrection. There is an ancient custom, the egg is cooked to the street children play. Their eggs from rolling down the hillside: Who broke the last egg, will win, all property of all of his eggs. White House to play this game every year, but is rolling eggs on the lawn only.
Rabbit is a symbol of Easter. Now every Easter, the United States the total size of a candy shop to sell chocolate made with the Easter Bunny and eggs. These eggs and egg is almost small, big melon big surprise, the children eat them with relish. To the relatives and friends, but also be a good gift.
What will win, money or knowledge? I look upon this matter for a long time and came to a conclusion that knowledge is more important than money. Without proper financial planning, we might eventually face financial problem even though we are filthy rich. Another similar situation would be, without a good understanding in English we will not be able to write good post to entertain our readers, isn’t it? So for a long run I think it is bad. Well, that’s only my personal point of view.
Knowledge will forever be the best & future ingredients of life as we know it.
If you got stuck in the middle of no-where (or maybe on another planet) with no transportation or no one around - will money get you home any better?
If you have to pick between a billion knowledgeable thoughts or a billion dollars - wouldn’t you rather spread your knowledge to others instead of thinking about becoming a billion dollars for yourself?
Money governs our system in which we live right now, but knowledge will defy & yet prove the facts about endless dollars that are spent in our worldly developing lifetime.
I would much rather (in almost any lifetime) have all the knowledge in the world than all the money in the world! Not because I don’t need to be rich, but because spreading that knowledge would be infinitively more bliss-full & pleasurable than passing around money to people everyday.
Finished reading the book the great navigator zheng he ", I feel from zheng he's navigation experience knowledge is power, if there is no advanced knowledge of zheng he's sailing cannot tell direction on the vast ocean, if you do not understand the customs of western countries, he can't normal trade in other countries; If he doesn't know military knowledge, he can't handle military dis*s well...
I was dee* impressed by the mention of such a thing in the book. A zheng he himself learned pirates to attack, then pretend to have no protection against its rise to the bait, surrounded by then all around, the cannon with a torch, a clean kill the pirate gangs rampant meg*ons, sublime.
Why is zheng he so much learned? It is inseparable from his clever and studious upbringing. When he was very young, he often listen to my grandfather and father speak pilgrimage of disasters, the mountains and rivers landscape and customs of western countries, like magnets tightly attracted by the zheng and heart. From then on, zheng he was filled with endless thirst for knowledge.
Only those who have knowledge can become like zheng he. Remember once a kite, in the beginning, everyone's kite is flying in the air, but suddenly the wind changes, many schoolmates kite fell down in succession, but a "little naughty" Ma Yongjian kite in our class didn't fall down, as he stood one side loudly shout: "run against the wind, lala fly." Some of the students were busy trying, but they did. You can't help admiring his rich knowledge of flying kites.
Yes, life is full of knowledge. Only those who win knowledge can win the future.
Since there is human beings on the earth, knowledge has sprouted in the wisdom of mankind, from the ancient to the highly civilized modern times, and the progress of every society. All show the great power of knowledge. The progress of knowledge has promoted the development of history and promoted the civilization of mankind. Knowledge is power!
Nowadays, it is popular in the world to see whether a country or a nation is prosperous and strong, and it depends on the level of people's cultural knowledge of this country and its people. I think that's not unreasonable. Even if a country is not rich enough for the time being, as long as it has a wise people and a tradition of valuing knowledge, it can be asserted that this country has a future. If a country and a nation are rich now, and support a group of "uneducated" people, the result must be deplorable. It is bound to fade away.
The tang dynasty in history formed the prosperous scene of "kaiyuan flourishing age". In addition to the emperor's enlightenment, the main reason was the full development of science and technology in all walks of life at that time. Domestic talents are abundant, and the state is powerful and powerful.
In ancient times, natural phenomena such as wind and rain and thunder were regarded as ACTS of god. When the drought came, the people killed the pigs and slaughtered the sheep. On the altar, kowtow to god, the priest to call the rain. To this day, it seems silly and ridiculous, but it is the inevitable result of lack of knowledge. Now we have the scientific knowledge, we have the method of artificial rainfall, even in the drought, the crops can grow very well. Oh, my god. We can't get our neck. Man can conquer nature, because people have knowledge.
Therefore, the prosperity and prosperity of the country cannot be separated from knowledge.

It is important for you to learn some knowledge about first aid in your daily life. If a person has an accident, he needs medical care before a doctor can be found. When you give first aid, you must pay attention to three things. First, when a person stops breathing, open his/her mouth and see if there is food at the bulk of his/her mouth. Second, if a person cannot breathe, do you best to start his/her breathing at once, using a mouth to mouth way. Third, if a person is hurt badly, try at once to stop the bleeding. Then take him/her to a doctor. If a person loses one third of his/her blood, he/she may die.
Many accidents may happen at home. All parents should know first aid in order to deal with common injuries which may happen to their children. When a person is bitten by an animai, wash the wound with cold running water before he/she is taken to see a doctor. When a person is burnt, wash and cool the area of the skin under the cold tap for a while. Then put a piece of dry clean cloth over the burn. If the person is badly burnt, take him/her to the doctor. If a person cuts his/her finger, clean it and put a piece of paper round the cut. Every bodyrshould know some first aid in order to save othe people's lives.
"Green card" nickname (because of the color) of the United States Permanent Resident Card,an identification document issued by the United States of America affording non-citizens of that country some of the rights its citizens enjoy,sometimes with the prospect of naturalization.
A United States Permanent Resident Card,also known as a green card,is an identification card attesting to the permanent resident status of an alien in the United States of America.Green card also refers to an immigration process of becoming a permanent resident.The green card serves as proof that its holder,a Lawful Permanent Resident (LPR),has been officially granted immigration benefits,which include permission to reside and take employment in the USA.The holder must maintain permanent resident status,and can be removed from the US if certain conditions of this status are not met.
Green cards were formerly issued by the Immigration and Naturalization Service (INS).That agency has been absorbed into and replaced by the Bureau of Citizenship and Immigration Services (BCIS),part of the Department of Homeland Security (DHS).Shortly after re-organization BCIS was renamed to U.S.Citizenship and Immigration Services
My name is li hua, and the most impressive thing of my life came to my life yesterday. When I walked near by a lake with my friend, he was falling into the lake, and I was so worried. I did't know how to swim, but I had to save my friend's live. I was shouting and asking someone to help. After that, the most impressive thing happened which was a young solder that jump into the lake without thinking, swimmed to the palace where my friend were, and got him out of the lake. After the young solder checked if there was nothing wrong with my friend, he went away. In conclusion, this young solder is the one who i respect a lot!
"Knowledge is power."We know knowledge is very important in this society.Now we study many subjects，such as chinese，maths，english，physics，chemistry and so on.To me ,English is my favourite subject because it is the most interesting subject .But I find studying English is very difficult.
So if you ask which subject is the most difficult to me.My answer will be English.Now I am a student,everyday I have more than one English classes,I like studying it very much and I hope I can study it very well,so I can talk with foreigners and know the foreign countries things,it is very useful.
It is always a hot topic that what should a boss focus on more, someone pay their attention to ability, and what they think is "ability is everything" ,but at the same time, some others argue that the opposite one--diploma is more important.
In my opinion, different choice should be made on different occasion, in other words, in different situation. If person the boss faced are young men who just graduate from universities, then diploma and how does the man show in university should be think about more, there is an old saying: a man should always be responsible for his job(在其位，谋其政）,as a student ,he has an obligation to do his study well ,and at this point ,a beautiful school report card is great, at least it proves his study ability, which is very essential for the coming days, and because he is so young that he owns the enthusiasm on work, which is also a necessary factor. But if whom the boss faced is a forty old man and just fired a company or be fired by the original corporation , then the boss would think a lot of such things as work ability , experience and so on. Then the diploma would be seen nothing as it is just a history to him.
All in all ,both of them are important, of course ,there are some else are also indispensably, to the boss ,before making a choice, think about what he want best, namely, which person he need best is most important.

I went out this afternoon. I didn’t have a exact purpose. I just wanted to have a look and learn something. I believe that knowledge is around us.
Knowledge isn’t just the points in the books. It includes lots of things. What you know about the city may be knowledge. The abilities of using things can be knowledge, too.
We are too busy studying at school. They know too little about our society. We don’t have enough time to get more information. We don’t have time to go out to see more and to explore more. Actually we are “the frog in the well”.
We used to study all kinds of things and get a great success. But now we have the only way to learn.
This morning I went to the market to buy some vegetables with my parents. On the way we all highly praised a young man in western—style clothes and leather shoes who was riding by. But he rode so fast that he knocked an old lady down carelessly.Instead of stopping，he pretended not to see this and rode away quickly. We were all very angry with the young man. To our happiness，a girl in plain dress ran forward at once，helped the lady up and took her home. We all praised the girl. From this we know we cannot judge a person by his appearance. A person who is dressed beautifully may not have a beautiful soul. Only a person who has a beautiful soul is really beautiful.

一般说来，看图写话中的汉语提示往往给定了有关的时间、地点、人物等相关的信息，有的还规定了文章所采用的体裁，如使用书信、留言、日记等。因此，在审题时我们一定要注意所给的汉语提示。
7. 文章中少用复句，多用单句;少用直接引语，代之间接引语。
图画式书面表达是高考英语书面表达经常采用的`形式，它是一种检查学生观察理解能力及语言运用能力的试题。主要特点有：
1、试题提供一幅或一组图画及提示，考生围绕给定的主题写出若干句语境相符、语法正确、意思连贯的句子。
2、此类题型关键是认真审题，从提示中了解所写的内容，列出提纲或拟个腹稿，然后分段表述，写出一篇脉络清晰、层次分明、文理通顺、意思连贯的短文。
3、图画提示类作文涉及的题材比较广，可以是故事、新闻报道、地点介绍或说明，也可能是书信或日记等。
要想写好图画式书面表达，同学们应注意以下几点：
1、仔细审题。确定文体、时态及人称。
看图书面表达以图画提供信息，但在汉语提示及“注意”中也蕴含着很重要的信息。如短文词数、文体及写作本文的原因或意图等。因此，在答题前一定要仔细审题，弄清文体、人称及所用时态。
2、找全要点，兼顾图内图外内容。
在动笔前，要认真读图、明确图示内容，把握好图中人物与人物、人物与地点、人物与画面以及图画内各部分的关系，以便做到既准确全面又详略得当。以多幅图作提示的，要注意图与图之间的关系，并注意图画内容的连续性及统一性(为统一主题服务，人称、时态等也要前后一致);若是以一幅图作提示，则要弄清楚图画中所有内容的联系，明确哪些与主题有关，哪些与主题无关，从而确定哪些该详写、哪些该略写或不写。
3、准确表达，尽量避免语法或拼写错误。
把要点列出后，要善于把分散的要点用正确、简明、地道的语句进行表达，并按一定的逻辑关系连接。正确用好时态，单词拼写正确，避免汉语式英语等。同时注意调整好要点的出场顺序。
4、仔细检查、修改。
核对图中要点是否遗漏。时态、语态是否正确。文章句、段、篇是否连贯。单词大小写、拼写、标点符号是否准确无误。书写工整、美观，一篇好的作文不但要内容写的好，字迹也要美观、工整、漂亮。

九年级下册物理学*方法
1.课前预*可以提高听力的针对性。预*中发现的困难是听课的关键，为了减少听力过程中的盲目性和被动性，我们可以弥补旧知识和新知识，从而提高课堂效率。预*后对知识的理解与教师的讲解进行比较，分析可以提高他们的思维水*，预*也可以培养自己的自学能力。
2.倾听集中的过程，而不是抛弃。专注是对课堂学*的奉献，是对耳朵、对眼、对心、对嘴、对手的奉献。如果你能做到这“五到”，就会高度集中，课堂上学*到的所有重要内容都会在他脑海中留下深刻印象。在讲课的过程中，要确保你们能集中注意力，不偏离对方。我们必须注意课前休息10分钟，不要做太激烈的运动或激烈的辩论或阅读小说或家庭作业，以免课后喘息、幻想、无法*静，甚至大脑开始睡觉。因此，我们应该做好上课前的物质准备和心理准备。
3，要特别注意教师讲课的开始和结束。在一堂课的开始，老师概括地总结了上一课的要点，并指出这堂课的内容是连接旧知识与新知识的纽带。最后，教师通常总结一堂课的知识，这是高度概括的，是在理解的基础上掌握本课的知识和方法的概要。
4,做笔记。会记录,但演讲中的重点,难点,使一个简单的总结记录,写下演讲的要点和自己的感受或创造性思维。审查和消化。
5.我们要认真审视问题，了解实际情况和物理过程，注意分析问题的思维和解决问题的方法，坚持从对方身上吸取教训，提高知识转移和解决问题的能力。
九年级下册物理学*技巧
图象法
应用图象描述规律、解决问题是物理学中重要的手段之一.因图象中包含丰富的语言、解决问题时简明快捷等特点，在高考中得到充分体现，且比重不断加大。
涉及内容贯穿整个物理学.描述物理规律的最常用方法有公式法和图象法，所以在解决此类问题时要善于将公式与图象合一相长。
对称法
利用对称法分析解决物理问题，可以避免复杂的数学演算和推导，直接抓住问题的实质，出奇制胜，快速简便地求解问题。像课本中伽利略认为圆周运动最美(对称)为牛顿得到万有引力定律奠定基础。
估算法
有些物理问题本身的结果，并不一定需要有一个很准确的答案，但是，往往需要我们对事物有一个预测的估计值.像卢瑟福利用经典的粒子的散射实验根据功能原理估算出原子核的半径。
采用“估算”的方法能忽略次要因素，抓住问题的主要本质，充分应用物理知识进行快速数量级的计算。
微元法
在研究某些物理问题时，需将其分解为众多微小的“元过程”，而且每个“元过程”所遵循的规律是相同的，这样，我们只需分析这些“元过程”，然后再将“元过程”进行必要的数学方法或物理思想处理，进而使问题求解.像课本中提到利用计算摩擦变力做功、导出电流强度的微观表达式等都属于利用微元思想的应用。

中考英语作文：知识和经验 Knowledge or Experience6篇（扩展7）
——中考英语阅读6篇
一般而言，这类问题被归结为单词量不够。要解决这个问题，是不是就要多背单词呢?单词是要背，但是要背到要点上。中考大纲，英语的要求是1600字，初 中生的阅读要求是200,000字，高中生约300，000字。这些阅读材料中的单词必然是以大纲中的1600为主，而剩余的，阅读中允许的3%的生词则 是在英语约300，000的总单词量中去选取。要想靠背诵完全解决生词问题，从这里看似乎不大实际。这里我有一点想法，
第一，不是每个生词都是必须看懂的。
英语中有大量的词总是大写第一个字母的，而他们也大多属于专有名词，表示人名，地名，事件。如Adela、Manchester、NATO。遇到这类词完全可以视若罔闻。
第二，有的词是乔装过的。
学英语的人都知道，英语中有些词通过前面或者后面加一些字母，就会变成另一个词。如，regular--irregular, kind--kindness,前者通过加-ir变成起否定形式，后者通过在后面加-ness,变成了名词。归纳起来，一般说前缀变词义(如肯否定)，后 缀变词性。只要记住这个原则，*时在学*是有意识的去检验，积累各种加前后缀的形式，你的单词量将是以倍数增加
第三，有的词是有"前科"的。
就阅读这个题型而言，有的词是在文章中有提示的。英语写作有个潜在的规则，词语若非不得已，不要重复。这是同学们写作时，老是告诉大家的话，而这也 是，大家做的阅读材料的作者在上学时，他的老师告诉他的话。秉承这个原则，我们可以在文章的结构*行出找到线索。或是反义词，或是近义词。根据文章的具体 情况，同学们不难作出一个比较有针对性的选择。
第四，有些词是必学的。
这里说得必学的就是，大纲要求的单词(如初中的1600词)，*时做题总是遇到的单词，生活中会经常遇到的单词。这些词是同学们发挥才智，施展所有做 题技巧的基础。在学这些单词时，要做到，有方法、有计划、有恒心。这里我提供一个自己觉得不错的方法，单词表上的词分类，单独把不会的列出来，分批背，不 用太急，一天5个，一周五天，一天总复*，一天总默写检查。*时总是遇到又不认识的，用一本笔记本把他们都记下来，划入单词表计划。生活中多观察，新闻， 公示语，商标都是提高英语词汇的窗口。

Soccer is the most popular sport in the world.
For those of you who are unfamiliar with the game I would like to give a brief introduction. 2 teams of 11 players compete on a soccer field at once. They can only touch the ball with their feet, head and chest. If they use their hands, the ball is given to the other team. Only the goalie can use hands. The objective is for each team to score on the opposing team's goal.
In 2004, the president of the International Confederation of Association Football, or FIFA for short, confirmed that soccer originated from China during the Warring States Period in 476-221 B.C. However, even though they followed the no-hands rule it was still very different from the soccer we know and love today.
Soccer changed and developed over the next centuries as it traveled through different countries around the world.
Modern day soccer started in England about 200 years ago. In May 21 1904, FIFA was established in Paris. From 1930, a World Cup would be held every 4 years.
Soccer is already a sport that we need in our life. There are about 800 thousand teams that usually play in matches. There are about 40 million players that signed up. There are a 100 thousand professional players.
As I mentioned before, traditionally, soccer matches have consisted of 11 players; however, now other competitive options are available including, five on five, seven on seven, and even beach soccer.
Soccer is really a sport that can be enjoyed by people of all ages and ability. I have loved playing for more than half of my life and I know that if you start today you will too.
Finished reading the book the great navigator zheng he ", I feel from zheng he's navigation experience knowledge is power, if there is no advanced knowledge of zheng he's sailing cannot tell direction on the vast ocean, if you do not understand the customs of western countries, he can't normal trade in other countries; If he doesn't know military knowledge, he can't handle military dis*s well...
I was dee* impressed by the mention of such a thing in the book. A zheng he himself learned pirates to attack, then pretend to have no protection against its rise to the bait, surrounded by then all around, the cannon with a torch, a clean kill the pirate gangs rampant meg*ons, sublime.
Why is zheng he so much learned? It is inseparable from his clever and studious upbringing. When he was very young, he often listen to my grandfather and father speak pilgrimage of disasters, the mountains and rivers landscape and customs of western countries, like magnets tightly attracted by the zheng and heart. From then on, zheng he was filled with endless thirst for knowledge.
Only those who have knowledge can become like zheng he. Remember once a kite, in the beginning, everyone's kite is flying in the air, but suddenly the wind changes, many schoolmates kite fell down in succession, but a "little naughty" Ma Yongjian kite in our class didn't fall down, as he stood one side loudly shout: "run against the wind, lala fly." Some of the students were busy trying, but they did. You can't help admiring his rich knowledge of flying kites.
Yes, life is full of knowledge. Only those who win knowledge can win the future.
It is important for you to learn some knowledge about first aid in your daily life. If a person has an accident, he needs medical care before a doctor can be found. When you give first aid, you must pay attention to three things. First, when a person stops breathing, open his/her mouth and see if there is food at the bulk of his/her mouth. Second, if a person cannot breathe, do you best to start his/her breathing at once, using a mouth to mouth way. Third, if a person is hurt badly, try at once to stop the bleeding. Then take him/her to a doctor. If a person loses one third of his/her blood, he/she may die.
Many accidents may happen at home. All parents should know first aid in order to deal with common injuries which may happen to their children. When a person is bitten by an animai, wash the wound with cold running water before he/she is taken to see a doctor. When a person is burnt, wash and cool the area of the skin under the cold tap for a while. Then put a piece of dry clean cloth over the burn. If the person is badly burnt, take him/her to the doctor. If a person cuts his/her finger, clean it and put a piece of paper round the cut. Every bodyrshould know some first aid in order to save othe people's lives.
"Green card" nickname (because of the color) of the United States Permanent Resident Card,an identification document issued by the United States of America affording non-citizens of that country some of the rights its citizens enjoy,sometimes with the prospect of naturalization.
A United States Permanent Resident Card,also known as a green card,is an identification card attesting to the permanent resident status of an alien in the United States of America.Green card also refers to an immigration process of becoming a permanent resident.The green card serves as proof that its holder,a Lawful Permanent Resident (LPR),has been officially granted immigration benefits,which include permission to reside and take employment in the USA.The holder must maintain permanent resident status,and can be removed from the US if certain conditions of this status are not met.
Green cards were formerly issued by the Immigration and Naturalization Service (INS).That agency has been absorbed into and replaced by the Bureau of Citizenship and Immigration Services (BCIS),part of the Department of Homeland Security (DHS).Shortly after re-organization BCIS was renamed to U.S.Citizenship and Immigration Services
My name is li hua, and the most impressive thing of my life came to my life yesterday. When I walked near by a lake with my friend, he was falling into the lake, and I was so worried. I did't know how to swim, but I had to save my friend's live. I was shouting and asking someone to help. After that, the most impressive thing happened which was a young solder that jump into the lake without thinking, swimmed to the palace where my friend were, and got him out of the lake. After the young solder checked if there was nothing wrong with my friend, he went away. In conclusion, this young solder is the one who i respect a lot!
"Knowledge is power."We know knowledge is very important in this society.Now we study many subjects，such as chinese，maths，english，physics，chemistry and so on.To me ,English is my favourite subject because it is the most interesting subject .But I find studying English is very difficult.
So if you ask which subject is the most difficult to me.My answer will be English.Now I am a student,everyday I have more than one English classes,I like studying it very much and I hope I can study it very well,so I can talk with foreigners and know the foreign countries things,it is very useful.
It is always a hot topic that what should a boss focus on more, someone pay their attention to ability, and what they think is "ability is everything" ,but at the same time, some others argue that the opposite one--diploma is more important.
In my opinion, different choice should be made on different occasion, in other words, in different situation. If person the boss faced are young men who just graduate from universities, then diploma and how does the man show in university should be think about more, there is an old saying: a man should always be responsible for his job(在其位，谋其政）,as a student ,he has an obligation to do his study well ,and at this point ,a beautiful school report card is great, at least it proves his study ability, which is very essential for the coming days, and because he is so young that he owns the enthusiasm on work, which is also a necessary factor. But if whom the boss faced is a forty old man and just fired a company or be fired by the original corporation , then the boss would think a lot of such things as work ability , experience and so on. Then the diploma would be seen nothing as it is just a history to him.
All in all ,both of them are important, of course ,there are some else are also indispensably, to the boss ,before making a choice, think about what he want best, namely, which person he need best is most important.
