English composition about invention?

In modern life, we have many inventions. These machines are very useful. They can do it better and faster than people. The washing machine can help us wash clothes. During this time, we have more time to do what we want to do. Printing machines quickly print a large number of books, newspapers and other things. Buses, bicycles, cars, trains, planes and ships make us travel faster than before. The computer is a wonderful machine. This is one of the most important inventions. Today, it is used in many ways. It can store information and solve mathematical problems millions of times faster than people. In a few years, computers may affect everyone's life. Even people in distant villages.

2./kloc-At the beginning of the 0/9th century, people began to use gas lamps, but gas was supplied by pipelines. Once it leaks or is blocked, it is very easy to have an accident, and people are very enthusiastic about the reform of lighting. In fact, Edison set himself an impossible task: in addition to improving lighting, he also wanted the electric light invented by Edison to create a power supply system. So he and his partners in Luomeng Garden made more than 600 experiments on heat-resistant materials and more than 600 kinds of plant fibers 1600 times before they made the first carbon filament light bulb, which can burn for 45 hours at a time. Later, he constantly improved the manufacturing method on this basis, and finally introduced a bamboo filament light bulb that can ignite 1200 hours. In the mid-1980s, Edison's electric light career was successful, which brought him a greater reputation than any previous achievements. Before the mid-1980s, he seldom made mistakes. After that, despite his great achievements, failures are common. One of Edison's most commendable behaviors is that he criticized alternating current, saying that alternating current has side effects and may cause death and injury, but he did not specify. Therefore, some people say, "It is very contradictory for a person like him who has made many inventions to attack other people's new inventions. "He opposed the use of alternating current in favor of direct current, so he lost in a fierce and stubborn argument. On the one hand, it reflects Edison's stubborn and old-fashioned shortcomings after he became famous.

At the beginning of the 19th century, people began to use gas, but the gas pipeline supply was leaked or blocked, which was prone to accidents. People were very enthusiastic about the reform of lighting. In fact, Edison set himself an impossible task: besides improving lighting, he also created a power supply system for Thomas Edison's electric light. And he and Meng Luoyuan's best friends repeatedly experimented with 1600 heat-resistant materials and more than 600 kinds of plant fibers, before they made the first carbon filament light bulb, which could burn for 45 hours at a time. Later, on this basis, he continued to improve the method of making 12 hours, and finally came out with this beaded light bulb. In the 9th century AD198th century AD198th century AD, Edison's electric light career was successful, which brought him more fame than any previous achievements. Before 1980s, he seldom made mistakes. After the intermediate level, although he made great achievements, he also failed frequently. One of Edison's least commendable actions is that he criticized alternating current, saying that it has side effects and may cause death and injury, but he did not add details. So someone said, "It is a very contradictory thing that many inventions made at sixes and sevens like him are attacked by other people's new inventions, Soder." He opposed the use of alternating current and direct current, so this approval failed in fierce debate and stubbornness. In this respect, it reflects the stubbornness that Edison began to develop old-fashioned shortcomings after becoming a celebrity.

3. I will invent a time machine in 2 1 century, which is my lifelong dream. Time machines allow people to go back in time to prevent disasters. It also allows people to travel far into the future to find a cure for incurable diseases, including cancer and AIDS. However, this machine may be abused, creating chaos in our world and even completely changing our history. Therefore, safety features are essential for my invention. The invention of the future time machine will certainly bring more benefits to mankind. I will invent the time machine in my life, because it is my dream. Time machines allow people to go back in time to prevent disasters. It also allows people to find a cure for incurable diseases including cancer and AIDS in the future. However, this machine may be abused by people who create chaos in our world and even completely change our history. Therefore, the security feature is the key to my invention. The future time machine will certainly bring more benefits to mankind.
