閱讀理解

　　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 (南極) 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.

A long walk in the desert or the mountains can be exciting. And it’s a great way to keep fit. If you carry a tent and some food, you can camp overnight. But wild places can be dangerous. Here’s how you can enjoy walking and camping safely.
Before your trip
☆ Tell someone where you are going and when you expect to return. If you don’t return on time, the people at home will know that you are lost or in trouble. They will know where to look for you.
☆ Make sure you’ve got a good map of the area that you’re going to.
☆ Make sure you’ve packed the right equipment for your activities. The desert is often hot, but nights can be very cold, and sometimes there are big rainstorms. In the mountains, the weather can change suddenly. A sunny day can turn cold and cloudy quickly.
The tools for survival(生存)
Sunglasses, sun hat, sun cream, windproof jacket, good walking shoes or boots, food, water, maps, compass, first-aid kit, matches, rope, knife, ground sheet,
the pack to carry your equipment.
What to do if you get lost
☆ If you’re in a car and it has broken down, stay with your car.
☆ If you are not traveling by car, make yourself easy to see. A signal fire can be seen at night. During the day, smoke may be used to show where you are. A brightly-colored blanket(毯子) may help rescuers to find you.
☆ Stay where you are.
☆ If you walk for any reason, avoid walking during the hottest part of the day. Morning and evening walking is better for saving your energy water.
☆ Keep yourself away from the rain, wind and sun, but remember: try to make yourself be in sight.
