　　Which invention was the greatest invention of the 20th century has been discussed many times.　Different people have different views. Some think the greatest invention was television, some　think it should be cars. But as far as I am concerned, the greatest invention of the 20th century　would be computers. The reasons for my opinion are as follows.

　　First of all, computers save a great deal of effort people spend on calculating. Before computers　were invented, people had to calculate manually. Sometimes it took scientists weeks, even months　to have a result. Of course, they might made mistakes during their calculation. That affected the　accuracy of data. But with the help of computers, people are freed from heavy calculation. If only　takes seconds to have a result which used to take weeks in the past.

　　Second, computers can simulate different environments that can’t be created in real life. In the　science research, sometimes scientist need to have a simulation environment to improve their　theories or as a basis of further research. Without computers it’s difficult to have accurate and　reliable results. But computers can make everything easy. Just input programs and data everything　will be done.

　　The reason I think is becoming more and more important nowadays. That is computer is the way　of access to the Internet. The Internet was developed based on the local area network(LAN) of　computers. Today, the Internet has become the fastest developing medium in the world. You can　find almost everything you need on the Internet, communicate with friends, read news, watch　movies, listen to music etc. But you must do all the above things on a computer. Can’t log in the　Internet means behind times today.

　　Although many other inventions of the 20th century brought great convenience to human or　changed people’s lives, computers have the most valuable contribution to human, and it will have　much more contribution in the future.

　　Many inventions have greatly changed the life of people.For example,when the electricity was　invented,people can use light,so that they would not be afriad of night.When the car was born,people can not have to go everywhere on foot.When the television entered into the history ,people can better know the world.But ,what is one change that should be rememered　about in the 20th century,the popularity of computer is undoubtedly the answer.

　　We can look into every good aspect of the computer,but I want to explore the most important role　the computer plays is that it greatly increases the efficiency of working.If you want to type a　paper,you do not need to worry about the errors,the word process will examine for you　　automatically.Also you should not be worried about losing the paper,you an save it in the　computer.In fact,that is just a piece of a cake for a computer,it can not represent the function of a　computer.When you enter into the international network,the computer will lead you into another　world.In this way,you just stay at home,but you can know everything happening in the world in every corner.Isn't it wonderful?Nowadays,many people choose to work at home to do work,as they can connect the offices by a computer.They say it greatly saves much time.

　　Second,the computer makes the communication much more conventient.In the past,we got the news by posting letters,in this way,it at least needed three days.However,if you send an electronic　mail by a computer,you get the news only three seconds.Not only saving the time,but it can　intense the emotion if you and your friends communicate more.

　　Third,computers also bring us much enjoyment.There are many games in the computer,for　different kinds of people.So people find another way of relaxing themself except watching　TV,seeing films.In fact,the computer games are not just only games,you can learn more from　them ,and they can also make you alert.

　　As the advantanges I explore above,I think the computer should be remembered about in the 20th　century.

　　There have been many changes, both technological and cultural, in the twentieth century. I　believe that one stands out above the rest: advances in medical science. The changes in medical　science go together with the changes in technological and cultural areas. One can move ahead　only with the help of the others. We can see the results of medical advances in three areas:　development of vaccines and antibiotics, expanded access to health care, and improved surgical　techniques.

　　When medical researchers learned how to prevent disease and stop it from spreading, the quality　of life for many people around the world improved. Today smallpox is a forgotten disease and　vaccinations are no longer required. Polio is under control and the vaccine is widely available.　The development of penicillin has helped many people recover from serious illnesses.

　　Although health care is not universal even in developed countries, it is much better than it used to　be. Local clinics, visiting nurses, and specialty hospitals have all improved the health care for our　communities.

　　If you should be unfortunate and require surgery, you are still lucky to have the surgery today　rather than even ten years ago. Now with microscopic and laser surgery, operations are more　efficient. You spend less time in the hospital and you recover faster.

　　I can't think of any other change that has affected the lives of so many people. Our health is　important to all of us. We all are thankful for advances in the area of medical science.
