以下是為您生成的一篇關于各個年代發明的生活用品的初一英語作文： In different times, many useful daily necessities have been invented. For example, in the 20th century, Willis Harvey Carrier invented the air conditioner. When he was 24, he worked for a heating company. At that time, in New York, the weather was hot and humid, which caused trouble for printers. So, the printers asked the heating company for help and Carrier was assigned the task. He found that cold water could cool the air. Finally, he succeeded and invented the world's first air conditioner. Another invention is the microwave oven. In 1940, two inventors, John Randall and H. A. Boot, designed a component called the "magnetron", which produced microwave energy. Percy Le Baron Spencer noticed that the radiation from the magnetron could generate heat. He used it to melt chocolate and pop corn. Later, in 1945, a microwave oven was produced for specific purposes. Also, there is the萬能膠. In 1942, Dr. Harry Coover was working for Eastman Kodak Company. He was trying to isolate a transparent plastic but accidentally invented a very sticky adhesive. Years later, this adhesive was recognized and became a popular product. These inventions have greatly changed our lives and made them more convenient. 點擊前往免費閱讀更多精彩小說
