Question

What do you think of the most important inventions in the world? The TV? The printing? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.

One of the simplest(最简单的) inventions is the toilet(冲水式马桶). Before toilets, waste ran into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.

Animal food is another important invention. Before the invention, most animals were killed（杀死） every autumn because there was not enough food for them in winter.  After hay (干草) became a kind of common animal food, animals could live through the long winter. The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the world would be difficult for the people above 45.
