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．

　　Every day some people are killed(杀死)while they are crossing the roads．Most of these people are old people and children．Old people are often killed because they can't see or hear very well．Children are killed because they are not careful．They forget(忘记)to look and listen before they cross the roads．

　　A car or a bus can't stop quickly．If a car is going very fast, it will travel many meters before it stops．Some people don't always understand this．They think a car can stop in a few meters．It's difficult to know how fast a car is moving．The only way to cross the roads safely is to look both ways, right and left．Then if the roads are empty, you can cross them．
