Here in Siberia（西伯利亞），the winter is always very long and it's very，very cold! It starts to snow in November and the snow won’t leave until May．The temperature is usually about-25℃，but it's sometimes much colder．When it's-35℃, children can’t go to school，but adults still go to work! We wear a lot of warm clothes，socks and boots（靴子），sweaters and fur coats．All the houses have heating（暖氣），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（可變的；易變的）．One day it's 25℃, and the next day it’s 10℃．People say that the weather was even colder in the past．
