What is the most important invention?

Introduction:

            In our society there’ve been diverse important inventions in biology, science, chemistry, ect. In centuries. For instance, the invention of lamp, fan, telephone, computer, vehicle that all need energy to set up especially electricity.Typically, electricity is the most invention that has significant role in our life.

            In prehistory, human being lived and did for living in darkness excepted sunlight in the daytime and torch at night. The living was very poor, difficult and undeveloping. Yet since electricity was invented, it has helped our life more modern and convenient. We can’t go on without using electric. Electricity is the greatest invention of human being’s history.

Body:

            First of all, the top important usage of electricity is lighting. How can people work in darkness? That is one of the reasons electricity is invented. In the prehistory, human being couldn’t do anything without sunlight. All the living had to be done before sunset or they could use torch to do something but it was very inconvenient. In contrast, people nowadays can working all day by using electricity, no longer depending on nature as the past. New York is a spectacular example to illustrate. It’s considered as “the sleepless city”. People can carry on their work at night by electric light. Giving light is the first but very important factor of electricity that helps human being not depend on nature anymore.

            Equally important thing of electricity is heating. People use electricity to cook the food and boil the water so that the food can be ripened, which is better for our health. Furthermore, electricity can be used for warming ourselves in the cold wet days in winter especially the people who live near north pole or south pole where the temperature is always under o degree, the preventing from reducing body’s temperature is also important beside the food.

            The last but not less important role is driving machines. While the science-technology is being developed strongly, in our farm, our factories as well as industrial zones, the strength of muscles are replaced with modern machines and robots which are operated by electricity. We can see these machines not only outside but also in our houses. These help us many things and save time for us. Our living is more and more depending on electricity indirect way.

The first time I met someone who became important to me

It was the destined day as I decided to take the karate’s course with my friend. I  met him-a really  special person on a situation that I’ve never expected. His name was Huy, my karate’s classmate as well as the teaching assistant. He wasn’t like any friends of mine so far, which made me more interested in trying to discover the mystery surrounding him.

On the first day I went to karate club, I was depressed by the pressure of practicing. It was highly hard with my beginning level so I poured out all my effort. I felt completely exhausted soon. The main encouraged me at that time was my main teacher. He was so kind and friendly. He heartily taught me what all he knew and showed me clearly what I had to do. But the most motivation was the teaching assistant. It would be unbelievable but “nothing but the truth” i've been attracted by him who had a cool face with fairy big round brown eyes. They were always in caution as if anyone was its opponent. He did so strict with everyone especially me.  He usually asked us to do something over our abilities and rarely reveal his emotion as if nothing could appeal him.That also was the secret of him I want to discover. Our teacher gave him useless comments because he was still stubborn as a innocent buffalo. I’ve got my revenge of him when I got the black belt. In my mind, he was a really ugly and wicked man with medium tall. I often teased him with my friends, yet I didn’t realize that he was the main character in all most my stories and became a part of my life. Time has passing,now I must grand that he isn’t bad as my belief. Just because they are his characteristics so it will be difficult to change it. But We can also see the effort despite a little improvement of him. Sometimes he also opens his heart and shares his thought as well as his feeling with others except me. I completely don't know why but I am still happy for him. Maybe we will be opponents forever. The special thing of him was His honey smile with 2 dimples and innocent eyes with faraway look could defeat any gentle lady. But they are out of my appeal that made him unpleased. He of course doesn't know the thing I like him most is his professional skill, not his appearance.

In my heart, he is quiet with some bad mood but also genuine. I really want to have some common hobbies with him and share together. No one is completely perfect, if we accept someone we also have to accept our shortcoming.
