     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.

     We know mosquitoes very well. Mosquitoes fly everywhere. They can be found almost all over the
world, and there are more than 2,500 kinds of them.
     No one likes the mosquito. But the mosquito may decide if she loves you. She? Yes, she. The male
mosquito doesn't bite! Only the female mosquito bites because she needs blood to lay eggs. She is always
looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn't like
your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just
remember you are chosen. You're different from the others!
     If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly
and quietly that you may not feel anything different. After she bites, you will have an itch(痒) on your body
because she puts something from her mouth together with your blood. When the itch begins, she has flown
away.
     And then what happens? Well, after her delicious dinner, the mosquito feels tired. She wants to find a
place to have a good rest. There, in a tree or on a wall, she begins to lay eggs, hundreds of eggs.

     Do you know why different animals or pests(昆虫) have their special colours? Colours in them
seem to be used mainly to protect themselves.
     Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because
locusts change their colours together with the change of the colours of crops(庄稼). When crops
are green, locusts look green. But as the harvest(收获) time comes, locusts change to the same
brown colour as crops have. Some other pests with different colours from plants are easily found
and eaten by others. So they have to hide themselves for lives and appear only at night.
     If you study the animal life, you'll find the main use of colouring is to protect themselves. Bears,
lions and other animals move quietly through forests. They cannot be easily seen by hunters. This is
because they have the colours much like the trees.
     Have you ever found an even more strange act? A kind of fish in the sea can send out a kind of
very black liquid(液体) when it faces danger. While the liquid spreads over(散开), its enemies(敌人)
cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

    Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big.
And they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).
    The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like
the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs.
If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the
leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
    Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some
places, the ground is very poor. It doesn't have all these important things, especially nitrogen (氮).
Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let's hope that some
of the bigger plants don't get the same idea!

     Many animals do strange  things  before    an earthquake(地  震).  This news may  be  important.
Earthquakes can kill people and knock down  homes. The animals may help to save lives.
     Some animals make a lot of noise before an earthquake. Farmers have told about this. Dogs  that
are usually quiet have started to howl(吠). Horses on farms have run around in circles. Mice have left
their holes and run away. Cows have given less milk.
     In a town in Italy, cats raced down the street in a group. That happened only a few hours  before
an earthquake. In San Francisco, a man kept tiny pet frogs. One Sunday, the frogs jumped   around
more than ever. They made loud noises, like bigger frogs. That night, an earthquake struck   the  city.
   People want to know when an earthquake is coming. Then they could get away safely. Right now,
there is no sure way to know ahead of time. Maybe the best way is to watch the animals.
