Modes of transportation

Transportation plays an important role in human's life. It is a useful system for carrying people and diverse goods from one place to another using vehicles, roads, etc. It is trully difficult to estimate how many advantages brought by different modes of transportation. However, the advantages of transportation can be classified according to three different kinds of transport: land transport, water transport and air transport.

Land transport provides people with the convenience and lower price. Land transport comprises all kinds of transportation moving on land. The most common land transport vehicle is the automobile. Others include buses, taxis, trains, trucks, bicycles, so on. As we know, most of human's activities mainly take place on land. Taking land transport is easier for people to travel around. Nowadays, every country has improved its own infrastructure such as highways, new roads, bridges, rails,... giving good conditions for people to use. Morever, when carrying goods from one location to another (especially short distances), using means of land transport is more convenient. Supposing that a farmer wants to transport his products to the consumer, he chooses the air transport. So first he has to drive the products to the airport. After taking a flight, he again drives the products to a certain place. Then from this place, his products are delivered to the consumer. Why do not he transport his products by land transport?, it only takes him a drive to come to his consumer. And the land transport is also less cost than anything else. For example, students and workers or the commuters using bus only spend from two to three thousands VND for two turns per day. In general, taking land transport is convenient and cheap.

The second transportation giving people a lot of advantages is the water transport. Water transport is the process of transport a watercraft, such as a barge, boat, ship or sailboat, makes over a body of water such as a sea, ocean, lake or river. It is a highly effective method of trasporting especially for large, heavy shipments. A ship's tonnage can reach thirty thousand tons, so it is no problem to move some bulky goods. Besides, as we know two third of our earth is sea and ocean, as a result, it is said that water trasport can bring many countries together. In fact, people can travel around the world by using a boat and products can be moved all over the world too.

Finally, the third transportation supplying people advantages is the air transport. Air transport includes public flights, private jets and even helicopter tours. Air transport is the most modern means and the second fastest method of transportation, after the rocket. A commercial jet indeed can reach up to 875 kilometres per hour, faster than many times when comparing with the speed of a boat or a motorcycle. In condition, aviation is able to quickly transport a huge amount of people and goods over long distances. Who estimates that up to 500000 people are on plane at anytime. Morever transporting by air is considered as the safest means (with the lowest accident rate). Accoding to a survey in 2008, 879 people died from airplane crashes while 1,3 million people died from car accidents worldwide. In short, air transport providing people with the highest speed as well as the safe.

Transportation is really helpfull for people. For instance, land transport gives us the convenience. Water transport solve our worry in carrying bulky shipments. And air transport give us speed. They are only some of the benefits brought by transportation. In the future, I believe that means of transportation can be farther developed and serve better for human's life.

The power of money

"Money makes the mare go"
People cannot live without money. Everyone indeed knows the value of money. It seems that nothing is more powerful than money. However, there are also opinions against the power of money that: money is just kind of paper having numbers on it and cannot give people the happily spiritual life. To me, money is a multi-purpose key, having money people can have everything.
Money can support our material life. People can buy foods, clothes and goods which are necessary to survive. With money people can freely choose where to live: a big house with yard and pool instead of a small one with noting, a nice vila instead of a low-roofed cottage. We can decide how convevient our house is, how good our accomondation is and how luxurious our car is. Is there anything greater than we can lie down on a comfortable sofe and watch films with a crytal liquid sceen television or play computer game in rainy days? Is there anything more pleasant than we can enjoy the cool and fresh air with the air-conditioning in the muggy and hot days. In fact, how can we satisfy our needs when we cannot afford to buy them? So money has it own power on allowing us to have such a better life.
Money can improve our spiritual activities easily. If we like, we can go to the concert, theatre and famous recreation center to relax. We also have chance to enjoy the beautiful landscapes by using money to travel around the world. Morever,money can help us learn more new and useful things. We can buy a lot of books and go to any schools, any universities or even go abroad to enhance our knowledge. Besides it, money is also a key of happiness. Having money we can do whatever we like and buy whatever we want. When the concerns about financial prolems disappear, our mind is free and comfortable. We will have the conditions to enjoy our own life. We will also feel pure happiness by contributing money to charity funds to help poor people and unlucky children. In general, money makes our spiritual life more colorful and happier.
Dispite of these ideas above, many people donot accept the power of money because they think it cannot buy a true love. We need to admit that love, which is a special feeling coming from heart, is difficult to be exchanged by any material. But saying that money connot brings us love and happiness is wrong. In fact, money is a necessary thing, from which love and other emotions can develope. Do you think and dare to love and marry a poor man and then have to worry about the poverty around you? It is true that money cannot buy love, but it can give us chance to win a heart. On the contrary, poverty is likely to break relationship because of the stresses and obstacles it brings. In real life, many couples have broken up because the arguments about financial problems continue to rise up and can not be solved. In short, money is a root, from which many things can grown smoothly including love and feelings.
What modern days are showing is that everthing existing in this world can be bought by the help of money. With money, people can have a pleasant and furnished life. It is really easier to face the rugged and difficult life with money and happiness even love goes through it.

Should we continue to eat fast food?

In countries throuthout the world and especially in the United States, fast foods become very popular. It seems impossible but one fast food company can sell more than a million of hamburgers just one day. In fact, people all know that these kinds of food containing a lot of fat anf salt are unhealthy but tend to be choosen because of their convenience. This rises up a debate whether people should boycott fast food or not. Actually, people should stop eating fast food because it can affect our health.
Many scientists have proved that fast food contains a lot of substances which are not good for health. Fast food includes hamburger, french fry, pizza, hog dog and many other kinds of food which are sources of fat and salt. These substances tend to be stored more than their necessity in our bodies and lead to obesity. We can see a typical example of obesity in the United States. This country has been called "a fast food nation" because people here consume a lot of fast foods. As a result, about 60 million American adults are classified as being obese with another 127 million being cverweight. Fat is considered as the most harmful substance because it increases the cholesterol in blood and the risk of high blood preasure. Sometimes, it can result in heart attack and rob people's lives. In general, the more people eat fast food, the more unhealthy and dangerous people's lives will be.
Eating fast food is simillar to a bad habit and an unhealthy lifestyle. Fast food is very addictive, so it is really difficult to give up this kind of food. People usually enlarge their appetites by eating more than their limit. This feeling is made because the fat in fast food affects our sense of taste. If this situation prolongs, it will gradually become a bad eating habit. People tend to eat more to satisfy their appetites and soon be overweight. As a result, they will feel themselves more heavier to move around and become lazier at working and doing exercises. In some other case, people can get stressed because they can not control their appetites. They obviously know their health status but cannot do anything else except eating and eating more. In short, eating fast food is a bad habit that makes people feel unwell.
People know that fast foods are unhealthy so why they continue to eat them. There is just one reason: it is more convenient to buy and eat fast food than anything else. When ordering food, people just wait for a few minutes then can eat their food at their table or wherever they want. People can eat it in the restaurant or take the food out and eat at work, at home, in the park, or even in their cars. Eating fast food is also inexpensive. Comparing with normal meal which is not only expensive to buy the ingredients, but it also takes a lot of time to prepare. Fast food is obviously cheaper and more convenient. However, people should pay attention to their health instead of the short term benefit of eating fast food. Why do people agree to pay a little money on unhealthy food, then they have to pay a large amount of money to treat serrious diseases brought by these kinds of food? Why do people just need the immidiate convenience, and forget how unhealthy and dangerous their lives are when eating fast food? In general, people should say "good bye" with fast food if they donot want their lives become worse and even a disaster.
In summary, eating fast food is not a good habit. People should stop or at least limit the consumption of these kinds of food. Fast food is not only a source of fat and salt-unhealthy substances, but it is also a large danger for people's health, even it can risk to people's lives.

What are the causes of plague?

You have certainly heard about Black Death-a bubonic plague which wiped out 25million people, approriately a third of England's population back in the 1300s. Plague is a bacterial disease, which still causes one to two thousand deaths per year. It is hard to estimate how many effects else of plague on the society, but in real life, plague is a terrible threat of human since the ancient time. In condition, what are the causes of plague?what makes plague such a tragedy of human? Accoding to scientists, the condition of climate change, the bad living condition and the people's contact with some infected animals are three main reasons that makes plague become an obsession of human.
Many scientists have proved that the outbreaks of plague appearing to be related to the climate change. The Yersinia pestis bacterium was discoveried in 1894 as the agent of plague. In moist climate condition, this bacterium become more active. A bacterium can reproduce a thousand of bacteria just in a few seconds. Taking advange of the convenience of weather, the fleas bringing this bacterium is also supported to be survival and reproductive. These parasites will follow their hosts to travel places to places and infect people with disease. Many scientists have discoveried that the Black Death in the 1300s is the result of the kind of weather condition-warm and wet. It is a good evidence to convince us that the climate change has affected on the development of plague. Nowadays, the phenomenon of global warming is affecting environmental condition worldwide. Warmer and wetter weather condition make the rate of people infected disease increase because there are more bacteria in the environment. As a result, more new outbreaks of plague found are the effect of climate change.
Plague outbreaks are most commonly found in rural areas. Rural areas are usually the poor areas with bad condition of living. These areas are normally the concentration point of overcrowding population and poor condition of hygiene,that causes rat-one of the hosts of intected fleas reproducing quickly. Besides, the economy of society is not good enough to supply residents the preventive treatment with antibiotics. Morever, the low awareness of residents in the consequence of plague is also a prolem. These residents usually donot report their infected relatives or animals to health department. Consequently, the work of seperating the patients can not be done well, and it is the main cause why plague spreads so quickly. These residents are also lack of the coorperation with their authorities in mission of killing in fleas, rats and infected animals. In fact, it is hard for the authorities to control the situation of plague in rural ares.
People can also be infected plague by contacting with some certain animals. Rats, quirrels, rabbits and lice are common sources of infection. Sometimes, pets like cats and dogs may become infected by such animals and make tranmission into human's body. People may easily get infection of plague just by a fleabite. The bacteria of plague can also enter human's blood through a little cut in skin if human handle or touch these animals. One other path help bacteria go straight into human's body is through the breath. People can breathe into lung an amount of bacteria of plague coughed by infected animals. These bacteria will travel to all organs following the bloodstream and they will soon invade human's body and make the outbreak of plague as we already know. Plague can spread with a threaten speed over a large of population, as well as the rapid reproduction of these animals risk to human when we contact with them.
We now maybe live in better condition, but can not forget the tragedy of death caused by plague since the past. There remain victims of plague on over the world who maybe are suffering the pain because of plague. In fact, plague, caused by the changing climate, the bad condition of living and the contact with infected animals, will be a bigger prolem in the future if human cannot find any method to prevent or make less effects from it.

What makes you happy?why?

Everyday you experience a lot of different events, either joyful or sad events. No matter what happens, I believe everyone has tried to gain the happy life. But have you ever thought what happiness is and how to have happiness? Someone define happiness as having a lot of money and being physically acttractive. Others think happiness is purely freedom, good health and love. In general, happiness is something greatest and is felt differently by different people. So what is the secret of happiness? To me, a good health, a true friendship, a gentle mind are factors to make happiness.
The first factor to make us happy is good health. Some people might think that having lots of money means having anything. But this material seems to lose its meaning if we donot have a good health. In fact, we have big house, luxury car and a mountain of money for what if we always lie on bed and suffer the pain of weekness. Therefore, a good health is the most valuable gift of nature, with it we can get everything not with money. Having a good health means having poweful vitality, so we can gain all the thing we like. It is really happy if we are healthy and have the oppotunity to experience the colorful, large world outside. Happiness lies on the strength of a good health to make our dream turn true.
The second factor to make us happy is true friendship. A true friendship is one of the most precious treasures of life. It is the motivation to help us overcome obstacles. Indeed, whenever we are sad, a little care or a kind act from a friend can cheer us up. Is there anything happy as we always have a close friend to share our sorrows with? We are no longer afraid of being alone because our friend is always there and willing to lend emotional support. We can confide everything about life to our friend, and the most impotant thing is that ther is always a person to listen to and understand what we say. Human cannot live without friends. True friendship will help human become stronger. In another way, friendship is the key of happiness.
The final factor to make us happy is gentle mind. A gentle mind means we arenot jealous at what people do and have. It doesnot have any meaning if we just look at and criticize other people. The important thing of life is just about enjoying our own life. We will feel more comfortable with a peace in mind. Happiness is not implied as envy which makes people be selfish and jealous. It is indeed miserable for whoever mantains the thinking of envy. They cannot see how beautiful this world is with the mind full of narrow- mindedness. Living means purely enjoying life. If we care so much about little things in life how can we have happiness. Therefore, gentle mind is synonymous with happiness.
In summary, there is no doubt that happiness doesnot go with material or money. Good health, true friendship and gentle mind are three main factors to help us reach the happiness. We should live a healthy and relaxing life and build lots of good relationships. I believe when we wake up in the next morning, this will be a different and new day which is full of happiness.

How to build a persional computer

With this developing technological age,the computer is becoming popular for human's need. Most people want to have their own computer to serve their lives such as: informing all the current events in the world, supplying a source of entertainment with music and games, comunicating with other people by chatting,...However, not everyone can afford to buy a personal computer. So to make everything acceptable with the expense, here are some steps to build a pc effective but simple.
To build a basic pc, we just need to buy some necessary components. First, go to an electronic equipment supplying store. Then ensure we will get good brand equipments. That means these equipments will have proper manufacture support. If we want our computer to operate well, it is important to choose good equipment. So going to a reliable store will be a wise choice. And here are the components necessary to build a pc: a motherboard_one of the important harewares, a processor with cooling fan,RAM, a video card, a power supply, case, a hard drive and some screws. Now just concentrate on and begin to build our computer.
The process of assembling parts of a computer is easy with two important steps. The first step is installing some components in the hardware. First, add processor and RAM to the motherboard. Most processors now use a socket to connect to the motherboard, so we need to align marked corners of processor and socket. Because when processor is running emiting a lot of heat, processor always comes with its own fan to cool. Then we install RAM with firm pressure. Second, install the CPU. Remember doing this step slowly and carefully, a little carelessness can ruin everthing because CPU is the brain of the computer. There will be an obvious connector for the motherboard and small four pin connector give power to CPU. Third, install the power supply. Use screws to secure power supply. Line up the power supply for placement into the pc case. Fan faces outside and wires faces inside. Finally, line up motherboard with plate and line up the screw holes with case. The second step is installing some components inside the case. At first, install hard disk by using the brackets and slide hard disc into appropriation. Then we will need to connect the power supply to the hard disk by using supplied cable. After that, install the CD drive also by using supplied cable. Make sure the drive is aligned properly. Finally, just install optional AGP video card. Now everthing has been done exactly excepting checking the operation.
Test on the operating of the computer is an important work to do. Test all the system is a process to make sure our computer running well. Now ready to get the computer set up. First, press the big round button on the case to activate the computer. If the monitor of our computer shows on, it means we have just done the right way. Next, check the software and the CD driver by playing a CD. If the computer accepts and runs the CD, it means we have been sucessful.
All the things now have been done exactly. With these above simple steps, a perfect persional computer will be sure to serve us. This work not only helps us save money, but it also gives us more fun because we have built a pc ourselves. Now we just need to operating the computer and enjoy our product.
