       Artificial flowers are used for scientific as well as for   decorative purposes (装饰的用处). They are made from a variety of   materials, such as wax (蜡) and glass, so skillfully that they can   scarcely be told from natural flowers. In making such models, skill   and artistry are called for, as well as thorough knowledge of plant   structure. The collection of glass flowers in the Botanical Museum of   Harvard University is the most famous in North America and is widely   known throughout the scientific world. In all, there are several   thousand models in colored glass, the work of two artist-naturalists,   Leopold Blaschka and his son Rudolph.

       The intention (目的) was to have the collection represent (代表) at   least one member of each flower family native to the United States.   Although it was never completed, it contains more than seven hundred   kinds representing 164 families of flowering plants, a group of fruits   showing the effect of fungus (菌类) diseases, and thousands of flower   parts and magnified detail (事情). Every detail of these is accurately   reproduced in color and structure. The models are kept in locked cases   as they are too valuable for classroom use.

The Australian continent is a land like no other. Its animals, plants and landscapes have evolved (演化) over one thousand years, and there are about a million different natural species (物种)in Australia. More than 80 per cent of the country’s plants and animals are unique to Australia, along with most of the fish and almost half the birds.

Australia has more than 140 species of marsupials (有袋动物),including koalas, wombats and the Tasmanian devil, now found only in the Australian wilderness. More than 750 species of birds have been recorded in Australia, 350 of which are found nowhere else in the world. Among them are the kookaburra, the rainbow lorikeet and fairy penguins. There are also 55 differernt species of macropods―the kangaroo family―native to Australia. They vary greatly in size and weight, ranging from half a kilogram to 90 kilograms.

The country has been making every effort to protect its natural heritage. Despite the large size of the continent, the majority of Australians live on the coast and in major cities―around 75 per cent of Australia’s population lives in city areas.

Australia is the driest continent on earth. Its center has one of the lowest rainfalls in the world and about three-quarters of the land is dry. These dry areas extend from the large central deserts to the western coast. Soils in these areas are very poor compared to other deserts. This has given Australians a great challenge.They have to make the best use of the variety of regions to meet the competing demands of agriculture, economy and conservation.
