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(×î¼òµ¥µÄ) inventions is the toilet(³åˮʽÂíͰ). 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£¨É±ËÀ£© every autumn because there was not enough food for them in winter. After hay (¸É²Ý) 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 forty-five. Without glasses, the world would be difficult for the people above forty-five.
