Do you know how to keep fish at home?
The fish need room. They must not be crowded（拥挤）. Fish need oxygen(氧气). Fish get it from water in the tank. There must be enough water for all fish in the tank. So the size of the tank is important..
In the tank many people put small plants(植物). They give oxygen to the water. Plants help in other ways, too. Fish can nibble(轻咬)on the plants. They hide in the plants and sleep, lay eggs there.
Both the plants and fish need light. You can put near a window. It will get light there. But remember: a window may let cold air in. The cold can kill(杀死) your fish. Too hot water can kill your fish, too.
The fish need food and you should feed them every day. Giving them too much food is bad. It will make the water dirty. However, the fish should get just enough food. They should finish the food in 10 minutes. No extra(多余) is left. When this happens, the amount(数量)of food is right.

Penguins are lovely animals. Most people like them. But now as many as 10 of the 17 kinds of penguins are in danger of disappearing. The number of penguins has decreased by ( 减少了) 30% since 1987.
Penguins are black and white birds that live in the southern part of the world. They are common in the Antarctic Continent (南极大陆) ,New Zealand, Australia and South America. Many live near cold waters (水域). But some live near warm waters in Galapagos Islands. Penguins cannot fly, but they are fine swimmers. The shape of their body helps them to survive. Penguins eat fish and krill (磷虾). They have short wings that help them to dive up to 900 feet to catch larger fish. They can swim 10-15 kilometers an hour which lets them protect themselves. They also have lots of body oil that helps in keeping them dry in the water.
The warming of the earth is the reason for the decrease in the number of penguins. The hotter and hotter air has caused ocean waters to become warmer. Higher water temperature has decreased the fish and krill. Some years later these birds are completely unable to reproduce. And many adult penguins die of hunger.
Too much fishing, exploration for oil and oil leaks (泄漏) also make penguins be in danger. Poisonous things in ocean waters are another danger. Penguins also have their enemies, including sharks, seals and sea lions.
