Inventions that Changed our Lives

By Rina Takamatsu

Several inventions have dramatically changed the way people live. For example, there is fire. Many years ago, our ancestors found fire, so they could change their life, food, and so on. Then we can think about the present day. For example, there is electricity. It changed our life because we have vacuum cleaners, washing machines, and lights. They are almost all automatic, so we can live in comfort. For example, there is the Internet. It is called “the best invention of the 21st century.” It changed our life because we can connect with people around the world. Then we can know the world affairs.
