Here in Siberia（西伯利亚），the winter is always very long and it's very，very cold!

We wear a lot of warm clothes，socks and boots（靴子），sweaters and fur coats．All the houses have heating（暖气），so it is never cold inside．In winter, we close all the windows to stop the wind from getting in and we don’t open them again until spring．

In spring and summer it rains a lot, and we don’t open see the sun．In summer it’s often about 25℃，but the weather’s very changeable（可变的；易变的）．One day it's 25℃, and the next day it’s 10℃．People say that the weather was even colder in the past．

What will the weather be like? Some people say they can know what the weather will be like from birds. When they see birds fly high out to the sea, they know it is a nice day, because birds don't like to fly out if it rains. When the weather is bad, the birds will come back to the beach. A big wind may come with a rain. Birds do not like to fly in a big wind. They may sit in a tree when rain is coming. Other animals can also tell the weather. It is a cloudy day. The rain is coming. Chickens are not quiet, and they are running here and there. Frogs are making big noise in the pool. If it is a nice day, the frogs will come out of the water.
