Most animals protect(保护) their young until they are old enough to take care of themselves. A fish that swims in the rivers of South America protects its young in a very strange way. This fish, a kind of catfish, uses its mouth to keep its babies from danger(危险).
When this catfish lays(产卵) its eggs, it carries them in its mouth. From what we know, it does not eat during this time. After the eggs hatch(孵化), the fish swims with its young to protect them. It opens its mouth when danger appears(出现), and the tiny fish swim inside. They swim out only when it’s safe again.

Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木),and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.

What do you think are the most important inventions of the past 2,000 years? The TV? The printing? The telephone? Or the computer? 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 common (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 common 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.
