1.The modern garden has a history going back many thousands of years. Early humans were hunters and gathered plants, and they didn't stay in one place for a long time. They traveled from place to place following the food (plants and animals) according to the seasons. About10,000years ago this slowly began to change; humans started to grow some plants, which meant they
could remain in one place. The first were vegetable gardens, where early humans cultivated different plants for food.

2. Early agriculture included not just edible plants, such as wheat, but also ornamental plants for decorative purposes. Plants for medicine were also grown, as were herbs and spices for flavouring or preserving food. Certain plants also had spiritual value and were used in religious ceremonies.

3. Almost everybody has heard about the
Hanging Gardens of Babylon which are called one of the seven wonders of the Ancient World. This garden was created around 2,600 years ago near the river Euphrates and contained many plants, flowers-, fruit trees, stone columns and waterfalls. It was designed in terraces so the river could water it easily and as a result it was green all year round.

4. In the past gardens were planted to honour the gods, or used in religious ceremonies such as funerals or weddings. Some trees were also sacred in some cultures, as were sycamores in Egypt. Ancient Greeks planted groves — small woods — for their Gods, and many cultures believed gardens were holy.

5. As gardens have developed over the years, design and beauty have become more and more important. People have learnt to control nature and to design gardens like a building. The gardens of Versailles, in France, are an excellent example of "garden architecture" — everything is symmetrical and even the trees are cut in a special way to fit in with the design.

A. The most famous garden

B. Works of art

C. Not a recent invention

D. The best place to rest

E. A tribute to Gods

F. Plants for different aims
