Переведите на русский язык отрывки из текстов по профилю специальности.
a) Bright, vibrant flowers seem to be popular with people today. More modern flowers such as lilies are now being combined with old favourites like the Irish and Chrysanthemum. The tulip is another very popular flower. In Australia the tulip is in season from April until September or October.
Bright yellows, oranges and reds are often put together in baskets, bowls and bouquets. Green foliage such as Eucalyptus leaves is added to break up the color.
The most popular type of flower arrangement is the bouquet. They are hand-held and less expensive than arrangements in baskets and bowls. There can be a variety of flowers in a bouquet or just one type of flower.
b) Gardening for food goes far back into prehistory. The earliest forms of gardens emerged from the people's need to grow herbs and vegetables, while rich people eventually began to create gardens for purely decorative purposes. Ornamental gardens were known in ancient times, a famous example being the Hanging Gardens of Babylon, while ancient Rome had dozens of gardens. The Hanging Gardens of Babylon are a World Heritage Site and one of the Seven Wonders of the Ancient World.
c) The ancient Egyptian garden differs from a garden in our days. Flowers like the iris, chrysanthemum, lily and delphinium (blue), were certainly known to the ancients but do not feature much in garden scenes.
Due to the arid climate of Egypt, the tending gardens meant constant attention and depended on irrigation. Skilled gardeners were employed by temples and households. Duties included planting, weeding, watering the plants, pruning of fruit trees, digging the ground, harvesting the fruit.
