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.

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.

任务型阅读(共5小题,每小题2分,计10分)
阅读短文,并按要求完成下列句子。
We know that many animals do not stay in one place.Birds,fish and other animals move from one place to another place at a certain time.They move for different reasons: most of them move to find food more easily,but others move to get away from places that are too crowded.
When cold weather comes,many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration is probably the migration of fish,which is called “salmon”(鲑鱼).This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old,it returns to its birthplace in fresh water.Then it gives birth and dies.In northern Europe,there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside,and many of them are killed when they fall into the sea.
Recently,scientists have studied the migration of a kind of lobster(龙虾).Every year,when the season of the bad weather arrives,the lobsters get into a long line and start to walk across the floor of the ocean.Nobody knows why they do this,and nobody knows where they go.So,sometimes we know why humans and animals move from one place to another place,but at other times we don’t.Maybe living things just like to travel.
