A great number of people in the world have never seen snow.Others see more of it than they want to. Hail is much more common; it happens even in deserts.
Hail is a small round ball of alternating layers(交互层) of snow and clear ice. It forms inside large dark clouds that you can see before or during a storm. There are two ideas about how hailstones from.
One idea shows that hail forms when drops of water freeze in the upper air.
As they fall, they collect more drops of water. They also collect snow. The ice and snow build up in layers. If you cut a hailstone, you can see these alternating layers.
The other idea says that hail starts as a raindrop. The wind carries it higher into the atmosphere(大气层), where it gets covered by snow. It becomes heavy and begins to fall. As it falls, it gets a layer of water, which freezes.
Then the wind carries it back to the snow area, and it gets another layer of snow. This can happen a number of times. Finally the hailstone is too heavy to travel on the wind, and it falls to the ground.
Only a thunderstorm(暴风雨), a storm with loud noises and lightning can produce hail, but very few of them do. Perhaps only one in 400 thunderstorms creates hailstones.
A hailstone is usually less than eight centimeters in diameter. However, hailstones can be much bigger than that. Sometimes they are as big as baseballs. The largest hailstone which people have ever recorded weighed over 680 grams and had a diameter of thirteen centimeters.
Hail can cause the death of plants, especially since hail usually appears in the middle of summer, when the plants are partly grown. If the crops are destroyed, it is too late to plant more, and the farmer has lost everything. In one terrible hailstorm in 1923 in Rostov, in Ukraine, twenty-three people and many farm animals were killed.

Do you know that in some parts of the world, people build temporary（暂时的）hotels made of snow and blocks（大块）of ice? These are known as ice hotels.
Unlike usual hotels, all the rooms in the ice hotels are made of ice. In some ice hotels, even the glasses for drinks are made of ice blocks. So they only serve cold drinks. Also, hot food is not served in the ice hotels, but guests can eat hot food at places nearby.
To keep warm, guests sleep in comfortable sleeping bags on ice blocks that are covered by mattresses（床垫）and reindeer skins（驯鹿皮）.
There are some places in the ice hotels that are heated, such as the bathrooms. This is because, even though it is not as cold in the ice hotels as it is outdoors（在户外）, indoor temperatures are still very low.
Perhaps the most interesting thing about the ice hotels is that they are rebuilt every year. They can be used only during the winter months. The ice hotels melt（融化）away when spring arrives. The ice blocks used to build these hotels are from nearby rivers. So, when the ice hotels melt away, they melt back into the rivers.
