(Final)The Effects of an Invention or Innovation in Modern Life

In the 20 century, one of the most popular inventions was the "Refrigerator". Nowadays, people use the refrigerator to keep the food fresh. The most important advantage of refrigerator is convenient to keep the food fresh. Before refrigerator was invented, reserving food for people was difficult, because the food is perishable at room temperature. People preserved some kind of food, like fish, pork or fruit to store for passing the hard time. But the preserved food is unhealthy and not fresh. Then the refrigerator was invented, people can easily keep the food fresh for several days. You just put the food in a refrigerator, close the door of refrigerator and then the refrigerator will keep the food cool because the food is imperishable at low temperature. Another advantage of refrigerator is "enjoyment". In summer, people will make something iced in the refrigerator so that they can enjoy the icy food when they feel hot. Also, many chefs can invent many diverse icy foods for people due to the invention of refrigerator, or the icy foods will melt quickly at room temperature without a refrigerator. Enjoying the icy food is an interesting part of summer life. Due to the advances of refrigerator, it has become a standard piece of equipment everywhere; it is hard for people to live without a refrigerator.
