For thousands of years men have dreamed about going to the moon. Now men have landed on it but living there will not be easy, because the moon is a dead world without air or water.
Man has lived on the earth under very hard conditions. At the South Pole (南极) men have lived for many months in temperatures of 75 to 100 degrees below zero centigrade.
Living on the moon will be even harder than living at the South Pole. Each night is two weeks long and the temperature drops to 200 degrees below zero centigrade. Each day is two weeks long, but the temperature rises to 200 degrees above zero.
If man hopes to live on the moon he will have to make his houses there strong and airtight (密封的).Instead of building up, he will have to dig below the moon's surface (表面) and live underground. The first men on the moon had to carry their own air, water and food with them from the earth. Later when men live on the moon, spaceships will have to keep bringing in more supplies. Many years later, man might be able to find ways to get his air, food and water supplies from the moon itself.
