Passage 5
Here in Siberia (西伯利亚), 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 grown-ups still go to work! We wear a lot of warm clothes: socks and boots, sweaters and fur coats. All the houses have heating, so it’s never cold inside. In winter, we close 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 often see the sun. In summer it’s often about 25℃, but the weather is very changeable. One day it’s 25℃, and the next day it’s 10℃. People say that the weather was even colder in the past.

On Nov.18th, 1908, three men went up in a balloon. They started early in London. The headman was Auguste Gaudron, and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way.
Soon they heard the sea. They were carrying the usual rope, and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to use the box to change the weight of the balloon. The three people were also carrying some bags of sand.
After the sun rose, the balloon went higher. It went up to 3,000 metres, and the air was very cold. The water in the balloon became ice. Snow fell past the men’s basket, and they could see more snow on the ground. The men tried to throw out some more sand; but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice.
　　At last they pulled the box into the basket. It was still snowing; so they climbed to get away from the snow. They rose to 5,100 metres! Everything became icy. They were very cold and  they decided to land. They came down in Poland　heavily but safely. They had travelled 1,797 kilometres from London!
