Types of animals

Animal world around us are very diverse and rich. They are diverse in species, body size, color ... Some species live primarily in marine life, the others live in salt-water, freshwater, land and parasites in the body of other animals, until the yearly polar ice. Some species have enormous size like blue whale (weighing 150 tons, 33 meters long), jellyfish tentacle length (nearly 30 meters long), elephants Africa ... but also some species are very small, so microscopic in size as the protozoa. So based on the character of life, lifestyle, and environment of life, scientists have divided the animal kingdom into three categories: birds, mammals, reptiles.

Birds are collection of species of vertebrates, warm-blooded, walking on two legs and lay egg. Modern birds carry the typical characteristics such as a feather, beak and no teeth, high metabolism. Heart has four chambers. Skeleton is lightweight but strong. All birds have foreleg which turn into wing and most can fly, apart from some kinds as the species of penguins, the ostrich. Likewise, they also have unique digestive and respiratory system that serve for flight operations. Some birds, especially the crow and the parrot are among the most intelligent species of the animal kingdom. Birds are herd animals, they communicate with each other through singing. They participate in many activities of the herd such as cooperation for breeding, hunting, moving and attacking to fight against the enemies. In short, birds also play an important role in human’s life. Most of them are used as food through hunting or raising.

Reptiles are found almost everywhere in the world, except South Pole. Reptiles are animals adapted to life in completely dry. So they have dry horns, long neck, eardrum in the ear cavity, weak limb but sharp claws. Lung has multiple partitions. Blood is mixed-blood, has two circulations. Reptiles are animals lay eggs that covered by thick membrane or limestone. Besides, reptiles are also called Poikilotherm and they very rich ovules. They have many benefits in life. For instance, in agriculture, farmer use snakes to kill mice. Being valuable food as turtles, tortoises; made medicine as python, snake; valuable products such as scales innovation, crocodile skin. Besides, they also bring some harmful effects such as toxic of snake when they beat people. In nutshell, reptiles are useful animal in human’s life.

Mammals are the species which are the highest in organization of vertebrate animals. They have a high and stable body temperature. Nervous system is highly developed, especially of the brain gray crust. Giving birth and raise their child by their own milk. This kind of animal has three tiny bones in the ear, teeth and brain develop more advanced than the other species, the heart has four chambers, and hot blood. Mammals have three main forms adapted to the environment: a first form, his neck and tail distinction clear, this form accounts for most of the species in mammals, these species are mainly terrestrial for example cat, rabbit, buffalo, cows. Second form is having wings, this form adapted to the air environment, able to fly. Between the fingers of the genus, with skin, like the wings of birds, for example: bat... The last form adapted swimming: There may be more change into fins. The skin becomes smooth, shine for example: whales, dolphins, and others. In general, mammals are the most developed in all other animals.

Birds, mammals and reptiles are the species which are disposed widely and popular over the world especially in tropical country as Vietnam. Not only does it provide us food but it also serves in many different fields as agriculture, business,…Nowadays; however, some kinds of animals become extinct because of human’s illegal hunting, and it makes a lot bad effects such as imbalance in wildlife. So we need to pass a strict law to protect these kinds of animals.

Advantages of travelling

Our forefather says that: “After a day’s travel, one gains a basketful of wisdom”. In fact, nobody can deny that we usually learn a lot after each trip. The more new places we visit, the more new things we learn. But some people say that traveling is not a good way, not everyone can afford to enjoy. To me, we should go traveling more because of its advantages.

Traveling makes us more modest and more reality. About modest, maybe at home we may think that we are the center of the world, and we are inclined to judge everything under our own conceptions. Traveling may change our way of thinking and widen our views of life. Observation and comparison will give us a right idea of what we really are. Thus, runs a Vietnamese say: “At home, mother is first and son is second; but when going out, they find that many others are better than themselves”. About reality, we can also learn so many new things about the land and the people through our daily dealing with people in different parts of localities which we will never learn from our reading or our lesson at school. Hence, we have a reality of view. For example, through TV, newspaper we know what is mountain, river, and how it is but through traveling we can see beautiful sights in direct: how jungle tropical is, how high mountain is, how deep river is, how immense sea is, etc. Therefore, traveling is the best way for us to be more reality and be conscious of the modest.

Traveling also served for relaxing and working. Newly married couples prefer going to a certain region with its beautiful scenery and its quiet atmosphere for their honeymoon. Elderly people or retired people prefer traveling to the places they have not had a chance to visit during their young age to know what the world is like before the end of their life. Scientists, biologists, and geologists, usually travel to remote regions to collect scientific data and information necessary for their research. For example, owing to traveling, Columbus discovered Africa and many other discoveries are made by traveling. Businessmen are the people who travel the most because they have to go abroad to look for new consumption markets, purchase material sources, and do market research. Above all things, traveling play an important role in our life.

Everything has its left side. Many people claim that traveling cost a lot of money for example traveling by plane, not everyone can afford. One more thing is fatigue, which happen while traveling because most of trip usually last very long. I admit that disadvantages and traveling is not totally a good way for those who do not have much time. But it is a little issue, we can solve easily. For instance, instead of traveling in original area by plane you can travel by train, use good service to avoid being fatigue. Traveling helps us enjoy the sense of freedom, get rid of tired, tense, responsibilities of hard work. That is a reason why more and more people go traveling.

Traveling is an essential part of education because of its advantages. As for me, I travel because I like to move from place to place, I can enjoy sense of natural sites. Traveling help me release stressed after tense semester at university. And after each trip, I feel that I bring back home something different from that I took on the departure day.

Should we get married early?

Nowadays, conception of young people about love and marriage is very simple. To them, it takes a minute to have a crush on someone, an hour to like someone, a day to love someone, a month to get married with someone. So getting married young is more and more popular in our society. In my opinion, this problem needs to be limited. I will analyze some disadvantages that they have to face.

Getting married early means losing some things in your life. First of all is freedom. Instead of going out with friends until mid night, you must stay at home to take care of your own family. Besides, at the weekend you also can not go shopping or go theater for entertaining, etc…All your hobbies have to change. In addition, only yourself, you do anything without giving much thought, but when you get married you have to give careful thought before acting with high responsibility. Then comes the time when will you have to think of buying a house for your own, providing it with furniture, and shopping other things necessary for your daily life. Once you spend all time for your living, you have no time to enjoy the life. The last one is you lose a chance to study further to improve your knowledge. And without further education, rarely do you make progress in your career. Thus, it makes you difficult in bringing up your children very well.

Despite this, getting married soon is also the way make you hurt easily. Because you are so young, you are not fully conscious of the responsibility of love and marriage. When you love, you look life through the rose-tinted-glasses, but only living together, you just realize that it does not come as your expectation. Besides, sometimes your marriage is the result of vague love not a real love. Therefore, you easily come to a divorce - destruction in the family.

However, some people say that getting married early also has advantage such as they no longer have to worry about taking care of their children well because of their old age. When they get older, the children are old enough to earn their own living and at that time the parents can enjoy leisure life beside grandchildren. In one aspect, I agree with this because they can bring up children better when they are strong enough to work. However, by any reason, in reality our life, not many people who get married and have children at their young age can have good condition of living. And the bad effects that they must encounter are not simple. In short, getting married soon is not good for young people.

Marriage is a sacred thing and a necessary stage of one’s life. And anyone always wants to have a happy marriage. To achieve that, we must have stable job and right conscious and an important thing is not getting married early, especially in our country. Because it really hard for young couple to support the children well. If the children do not have well brought up, they will do nothing for family and for society.

Uncle Ho_ the greatest father of Vietnamese people

If anyone ask me “Who is the greatest person in your country?” At that time, not only me but all Vietnamese also answer immediately without hesitating “ That is Uncle Ho”. He has gone down in history as a significant pride of Vietnam country. His contribution to our nation is extremely important and considerable such as: lead Vietnamese successfully in fighting against enemies to achieve freedom and happiness, build Vietnam from feudal country to socialist country, bequeath many valuable lesson about morality and thought for later generation.

The first important contribution that he brings for Vietnamese is freedom, independence, and happiness. Because of a fierce patriot, when enemy invade our country, he can not stand seeing our compatriot oppressed, he decide to go abroad to find solution to liberate country. He has gone many different countries, suffer many difficulties. Finally, after many years scurrying, he also succeed in searching a way to save his country. When he come back, he led Vietnamese fight against enemies with talent, bravery and union. As a result, nowadays, we can live in peace and independence country, enjoy freedom and happiness, have enough condition to study and work. Struggle to gain independence and freedom of the people of Vietnam has become a shining example and contribute positively encourage colonial nations in the continent to liberate their region. World map was redrawn for clarity changes. Vietnam's position in the international is enhanced markedly. So Uncle Ho is not only great person in original area but also in over the world. Thus, all of us must be grateful to him for his devotion.

Besides bringing freedom and happiness for our country, he also has make Vietnamese have a new life by building Vietnam from feudal country to socialist country. If in feudal period, you have to be oppressed, could not live with enough meaning of humanity, now with socialist, you can own your life, take part in building the machinery of government . So socialist is said that ” It is the most equal society in the world”. Moreover, Uncle Ho used to say that “ Communism is only to save mankind, giving everyone regardless of race and origin of freedom, equality, fraternity, solidarity and prosperity on earth, job for the sake of people, joy, peace, happiness, in short a world republic true” The purpose of socialism is to continuously raise the living standard of people, material life and culture of the people and built by the people. Therefore, this is one of the most contribution which Uncle Ho bring for Vietnam country.

Last but not least is valuable lesson about morality and thought which he bequeath. Our country, we are very happy to have a great revolutionary leader, a great person as President Ho Chi Minh who had left for the eternal moral example. Looking at this, we will see our soul become clearer, our actions is better, human personality is more advanced. It is example of great person but it is very simple, everyone can learn from to improve themselves. Some of them are: fierce patriot, union, saving, honesty, laborious, etc..

Uncle Ho, who is the greatest father of all Vietnamese people, is still in heart of Vietnamese although he goes far away forever because all things that he brought for Vietnam country help our nation have a new life and more developed. Once again, as a student we need to remember Uncle Ho’s saying: “ That nothing is more precious than independence and liberty” so that we try our best to study to maintain all sacred things we have.

What make you happy

HAPPINESS
There are certainly several ways to make a man’s life worth living and one of them is happiness. That is a reason why humanity has always been in search of happiness, but happiness is like a shy bird. If we hunt it, it flies away. The conceptions of happiness are many and various. Some think that earthly pleasure and successful are the essential conditions of happiness, some others look for happiness in their regular work and daily duties and others identify happiness with a peace of mind and a clear conscience. In my opinion, three things that make me happy are: money, healthy, and love.

“Money makes the mare go”, with money I can solve many problems, do whatever I want. That is the reason why I said money made me happy. I all admit that money does not have absolute power, but we never can deny its decisive factor in the career of a man, its important role and its value in their daily activities. Money is important in many aspects of life. Through daily experience, everybody knows that without money, we will have nothing. For example, when I want to do charity, I cannot help by word, I must help by specific action. It may just a little money, but to poor people, it is a whole possession. To them, money enables them to buy the things extremely necessary for their lives such as food for meal, clothes for keeping warm. As for a university student, money provides me with more opportunities for my father study. I can go abroad to widen my knowledge, buy books and equips all which serve for my study. Besides, money can assure me a happy material life. I am able to enjoy modern material facilities that life can offer. It makes me possible to travel abroad for my holiday, to entertain myself and to enjoy life. Therefore, if you know how to use your money so that it is both useful to you and to the society, I think that in some respect, money is one of the factors leading to happiness. It will make your life worth living and more meaningful.

Besides money, healthy is one of the important things makes me happy. People say that “health is gold”. It is totally exact. Because when I feel healthy, I can do anything, always in a good mood, do not worry about any diseases. That is also a reason why clear mind is always in a healthy body and bad health people cannot get along well in life. When we are young, strong, we cannot imagine what it is to be weak and sick, but our body become painful or sick, we later learn by bitter experience that health is something priceless. A person in poor health can seldom be happy. Poor health prevents us from carrying on our daily work. Especially, a weak student cannot finish their study well, cannot take part in any social activities. Thus, good health is a main factor of happiness. If I am asked whether life is happy, I can say that “ It depends on my health”.

The last one which is also the most important to me is love. It is a common saying that “No love can last long, which is all give on one side and all take on the other side”. So love and to be loved are the factor leading to happiness. When you love, you will have motivation to do anything. Love also help you have a positive outlook about life. You can never live happily without love, love is the most precious thing in life. With love you will be ready to help the people around you, it will bring happiness not only for yourself but also for the others. And, maybe, to be loved is the feeling that everyone want to receive and it is the best way make us happy. Love of family is the most sacred thing and living in happy family is the happiest. If you get any problem, they will share with you, help you overcome. If you feel discouraged, family will encouraged you to persevere. When you are in bad mood or contrast, they always stand by you, share with you. So, you do not have to suffer sorrow by yourself. In short, love and to be loved are factors which contribute to make your life happy.

Be certain that many questions are given: what is happiness? Where can we have happiness? How is meaningful happiness? etc. And answer is very simple, because a famous person used to say that “Happiness is made, felt by yourself”. So, each person has personal way to feel happy, but to me: money, health, and love are the best. And beside that we can find happiness easily through knowing how to live with what we can afford, never dreaming of what is beyond our reach.

How to build a PC

Computer is not luxury product any more in our current time. Everyone can buy and use it easily. And tendency of young people to make PC for their own computer more and more popular. Beacause when they make it by themselves they can buy and choose good component parts which is good for their PC. But how to build a PC? I used to build a PC, so with my experience I think it is not very difficult if you do some following below steps.

Before beginning, you have to prepare enough equipment. They include: motherboard, processor, ram, hard drive, video card, case, power supply, optical drive, mouse, keyboard, speakers. How to buy them? You can go to electrical shop to buy all of them. How about a process? You can go to internet shop and look for some websites about them. Asking friends some advices about it is also a good idea. For the first time, I met many difficulties, I don’t know where to start. Fortunately, I just found out a good website in which I was instructed carefully each step to make PC. Therefore, it just took me half a day to complete. It is really out of my expectation. Now, I am very proud of telling you how to assemble a PC quickly and without difficulties.

When everything is in order, we start to assemble. Rule of process is you have to assemble simple equip first and from inside to outside. First, adding processor and ram to motherboard. Be sure that processor come with its fan and align marked corners of processor and socket. Especially, installing ram with firm pressure in order to protect its function. Second, we will assemble power supply, cover plate, motherboard standoffs and wipes. Cover plate and spacers will come with the motherboard. You will hear a click when it in place. Be careful when installing the screws. Just remember that fan side face outside and wipe face inside and use screw to secure power supply. There have small four pin connector give power to CPU. Each connector will have obvious port. The last is inside case,you have to install hard drive and CD drive. You need to choose a suitable place to put hard drive on available case. Screwing two sides to secure hard drive with case. When installing hard disk, we use bracket which comes with screws. Then,sliding hard disk into appropriate slot,connecting power supply to the hard disk. Making sure that drive is aligned properly.

After finishing installment, you need to check again to confirm whether it work or not. First,you start-up PC by press on button. If the signal light is bright, and you hear the sound like “bip”, it prove that your PC can run well. Then, you should look inside the case to make clear that the fan of processor is spinning. Because only when it spin, it will help your prosessor to release the heat, it also mean that your processor can work well for along time. Next, checking connection between PC and monitor, if on the screen appear any data, this thing mean monitor and PC has connected. The last one is checking CD-Rom, you have to assure that it can work normally such as it can push the disk outside and contrast. Finally, covering the case and screwing carefully.

Nowadays, each student need to have a computer in order to serve for studying. Because with the help of technology, students can learn more information and learn it quickly. But not anyone can afford to buy it. So, installment a PC by ourself is not only a good solution but also a way to save money and make us have a lot of fun. Those above steps is very simple and useful. However, if you failed in the first time, just remembered “Beginning is the difficult” and “Never, never give up”.

Quality of a good human

A good human is always loved, respected, admired by the other person. That is also the reason why through centuries, humanity has always wanted to be a good human in all fields. But to become a good human is not easy. It has to start from the bottom of their heart, otherwise it like a fugitive bird. The more we run after it the farther it flies from us. Quality of good human is something relative. It depends on how people feel about it. The conceptions of its are many and various. In my opinion, the most important qualities of a good human are: kind-hearted, tolerant and responsible for themselves, society.

Kind-hearted is a good quality of a good human that we can realize easily because it is the action which bring fun, happiness for the others and for themselves. When anyone have a kind-hearted they will be ready to help the people who have difficult circumstance or disable. They love by the heart, help by vital action not by word. They usually sympathize with unlucky life. They help everyone and don’t expect anything return because to them this is happiness, responsibility, useful thing that they need to do. There are many ways to help. However, how to help meaningfully is still a big question. For example, helping the poor not only mean provide them with enough food for the meals and clothes to keep warm but also make opportunities for them to overcome difficult life and have a stable job. Many ideas said that sometimes they help the others because of their individual purpose not for conscience. It is a sad thing for our society. As a result, kind-hearted is a good quality and a good way to prove person whether they are good person or not.

Besides kind-hearted, tolerant is also a important quality of a good human. Because tolerant will help them have another view to life. They know how to share and sympathize with unlucky person. They always judge anything with positive view, ready to tolerate with worthless mistakes. They are not jealous of others’ happiness, so they make relationship between people and people more nearer. However, today, many people misunderstand meaning of tolerant, they are willing tolerate any serious mistake in order to show that they are a good human. What a pity when it happen. Therefore, tolerant is a good quality of a good human but we should use it in suitable situation so that it can make our mind peace, our conscience is not tortured, become clearer.

The last which is one of important qualities is responsible for themselves and society. When having high responsibility, they will do anything with careful thought so that they don’t make bad effect on the others. In addition, they are also in charge of their words and actions. To society, they know to share difficult problem in community, try their best to contribute in development of country. A person who have responsibility also know how to keep themselves away from bad social problem, propagate,instruct everyone see and do. Especially, they must have brave enough to face the ups and downs of life so that they can fight against negative problem in society.

“Living in life need a warm heart to love”. So each of us have to do the best thing we can in order that we will become a useful citizen for our society and a good human in the future. And the dream will come true if we are: kind-hearted, tolerant and responsible.
