People living more than three thousand meters above sea level find it difficult to raise vegetables all year long. People living in the highlands of Peru and Bolivia, for example, cannot grow vegetables outdoors during the months of May through September. It is very cold in the highlands at that time of year. If traditional farming methods are used, vegetables will not survive.
However, there is another way to grow vegetables throughout the year in cold areas. It is a method of gardening developed by a private agency called World Neighbors. The method uses “hot houses” built below ground. A hot house is a building covered with plastic or glass in which vegetables or flowers are grown. The traditional hot house is built above ground.
The air temperature is cold in the highlands of Peru and Bolivia during the winter. But, the winter sun is hot. So, World Neighbors advises farmers there to build hot houses below ground. The design is simple. The material does not cost much. Here is how World Neighbors says to build it: Dig a hole two and one-half meters wide and six meters long. Make it about two meters deep. Build wall with a door in one end of the hole. Dig steps from the ground down to the door.
Now, build a wall along the top edge of the hole. Make it about one-half meters tall. Earth bricks work fine. Build two shorter walls on the ends. These will be uneven; one side will be as high as the existing wall. The other side will be at ground level. Leave a small opening in each of these sloping walls. This prevents the hot house from becoming too hot. Now, make the roof. Build a wood frame. Cover it with clear plastic. Connect it to the brick walls.
The underground hot house we have described is large enough for two raised vegetable beds. Each is one meter wide and six meters long. Each is seeded and watered just as if it were in a garden above ground.
The dirt walls protect the growing plants from the cold. The clear plastic roof permits the sun’s heat to enter. At night, the roof should be covered with straw. This helps prevent cold air from entering. An under ground hot house this size will provide enough vegetables for one family. Groups needing more vegetables can make it bigger.

　　Skyscrapers（摩天大樓）and domed（拱形的）stadiums can amaze us. These modern "wonders of the world" are great achievements in building. But our modern buildings may seem small when compared to some ancient strutures. Our buildings may be large, hold many people, and protect us. However, many ancient structures stand as some of the greatest achievements in building. Ancient builders used great creativity and physical strength to plan and complete them.

　　Stonehenge is a huge stone circle in Europe. It was built more than 4,000 years ago. The circle has stone slabs（厚板）that stand up to 30 feet tall. The heaviest stones in the circle weigh about 50 tons. How did people build Stonehenge without modern equipment? Scientists have studied it for years and think it probably took more than 30 million hours to complete the project.

　　Tourists in Africa like to see the Great Pyramids of Egypt. These tombs for Egyptian kings were built over 4,000 years ago. Each tomb has walls shaped like triangles（三角形）and a square（正方形的）base. The largest pyramid is more than 450 feet tall and contains more than two million stones. Each stone weighs more than two tons. Some even weigh as much as 200 tons. More than 900 workers worked to move the largest stones into place.

　　The stone faces are unusual structures on Easter Island. The faces are 12 to 20 feet high. Islanders made them more than 1,000 years ago. We do not know why they built them. There are more than 600 stone faces on the island. The great number is surprising, since Easter Island is only 11 miles long and 15 miles wide.

　　They give only a glimpse of the ancient achievements in building. If we look back through history, we can find many more examples of marvelous（非凡的）structures built without the aid of modern tools and equipment.

Skyscrapers and domed stadiums can amaze us. These modern “wonders of the world” are great achievements in building. Some skyscrapers stretch more than 100 stories toward the sky. The Sears Tower, the tallest building in Chicago, soars 110 stories above the city. Domed stadiums like the Astrodome in Huston, Texas, have seats for thousands of people. Inside these stadiums, people can watch their favorite sports without the bother of heat, cold, rain, or snow. Modern skyscrapers and domed stadiums are certainly marvelous structures!
On the other hand, our modern buildings may seem small when compared to some structures of the ancient world. Our buildings may be large, hold many people, and protect us from the weather. However, many ancient structures stand as some of the greatest achievements in building. Ancient builders used great creativity and physical strength to plan and complete these buildings. Today, we could make most of these ancient structures easily, but it is hard to understand how people built them hundreds and hundreds of years ago.
Stonehenge is a huge stone circle in Europe. It was built more than 4,000 years ago. The circle has stone slabs that stand up to 30 feet tall. The heaviest stones in the circle weigh about 50 tons. How did people build Stonehenge without cranes or other modern equipment? Scientists have studied Stonehenge for years and think it probably took more than 30 million hours to complete the project.
Tourists in Africa like to see the Great Pyramids of Egypt. These tombs for Egyptian kings were built over 4,000 years ago. Each tomb has walls shaped like triangles and a square base. The largest pyramid is more than 450 feet tall and contains more than two million stones. Each stone weighs more than two tons. Some of the stones weigh as much as 200 tons. More than 900 workers worked to move the largest stones into place.

There are more than 600 stone faces on the island. The great number of stone faces is surprising, since Easter Island is only 11 miles long and 15 miles wide.
Stonehenge, the Great Pyramids, and the stone faces on Easter Island give only a glimpse of the ancient achievements in building. If we look back through history, we can find many more examples of marvelous structures built without the aid of modern tools and equipment.
