What do you think are the most important inventions of the past 2,000 years? The TV? The printing? The telephone? Or the puter? A report shows that these are not the only important inventions. Here are four other important ones.
Paper is one of the most important inventions. You can’t have printing without paper. In 105 AD, Cai Lun invented paper in China. Long before the printing and Internet, Cai Lun’s invention allowed us to write down information, stories and history.
One of the simplest (最简单) inventions to save life is the toilet. Before toilets, waste ran into the rivers from people’s houses. Illnesses were mon (普通的) in big cities, and it was often difficult to find clean drinking water.
Animal food is another invention. Before the invention, most animals were killed every autumn because there was not enough food for them in the winter. After hay (干草) became a kind of mon animal food, animals could live through the long winter.
Reading glasses is the fourth invention. People start getting far-sighted (远视) from the age of 45. Glasses mean that anyone can read, write and do “close work” after that age. Without glasses, the world would be difficult for the people above 45.
