world. Canada is one of the few developed nations that is a net exporter of energy. Canada has vast deposits of natural gas on the east coast and large oil and gas resources centred in Alberta, and also present in neighbouring British Columbia and Saskatchewan. Canada is one of the world's most important suppliers of agricultural products, with the Canadian Prairies one of the most important suppliers of wheat and other grains. Common agriculture plants are barley, oats, rye and wheat. Canada is the world's largest producer of zinc and uranium and a world leader in many other natural resources such as gold, nickel, aluminium, and lead; many, if not most, towns in the northern part of the country, where agriculture is difficult, exist because of a nearby mine or source of timber. 7. Climate Because of its great latitudinal extent, Canada has a wide variety of climates. Ocean
Australia. The soft-feathered, brown, flightless birds reach up to 2 m in height. The Emu is common over most of mainland Australia, although it avoids heavily populated areas. Emus can travel great distances fast, if necessary, can sprint at 50 km/h for some distance at a time. They eat a variety of plants and insects. Emus are farmed for their meat, oil and leather. The Kangaroo is a common marsupial from the islands of Australia and New Guinea. There are 47 species of them. Kangaroos can hop up to 74 km per hour and go over 9 m in one hop. These shy animals live about 6 years in the wild and up to 20 in captivity. Most of them are active at night. Many kangaroos are in danger of extinction. Kangaroos eat grass, leaves, and roots. They swallow their food without chewing it and later regurgitate a cud and chew it. They need little water; they can go for months without drinking,
Australia Fact file: Australia comprises a land area of 7 686 850 square kilometres. Its population is about 21,3 million people. Australia's capital is Canberra. The national language is English. The official name of it is the Commonwealth of Australia. It's divided into six states and two territories: New South Wales, Queensland, South Australia, Western Australia, Tasmania, Victoria, Australian Capital Territory (ACT) and Northern Territory. Symbols: Australia had the British flag as their official flag until 1901, when the Commonwealth of Australia was formed. Over 30 000 entries attracted the official competition. Five of them, which contained almost identical designs, were placed equally first. The Australian flag symbolises Australia's historical links with Britain, because it has British flag on it, and Australia's location in the southern hemisphere, because it has stars of the Southern Cross on it
Natural Zones and Flora. There are five distinguishable natural zones in Australia. In the very east there are wet forests (1.) that occupy the space between the Great Dividing Range and the eastern coast. Westward from the Great Dividing Range the wet forests give place to beautiful grasslands with some trees . These grasslands are called the savannas (2.). Farther west the trees disappear and the bushlands (3.) begin. The real desert (4.) occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees (5.). Most of Australian trees are kinds of eucalyptus trees (or gum trees to Australians) and acacia ( wattle to Australians). Eucalyptus trees are found everywhere in Australia. There are many kinds of them and they greatly differ in size. One kind, the great mountain ash, can grow to 120 metres and it grows in the wet forests in the eastern part of the continent.These strong trees do not die when there are forest fires. Some other kinds a
to Western Australia in 1868. About 160 000 convicts arrived in over 80 years. The convicts were mostly poor townspeople. Only few of them were from wealthier classes. The building of a new society based on these people was an outrageous challenge. The most cunning and skilful of the convicts became later the founders of prominent colonial families. Until 1830s the convicts were harshly punished for almost no reason, flogging being the most common penalty. During the 1850s, the settlement was boosted by gold rushes. Gold was first found at Bayhurst in 1851. Scarcity of labour (tööjõupuudus), the vastness of the bush, and new wealth based on farming, mining and trade all contributed to the development of uniquely Australian social institutions and sensibilities. The idea of unifying all the states first came to Earl Grey in 1847. It was only on January 1, 1901, that the Australian colonies federated to become the
Today many diseases are well known and can be cured. Such diseases are flu, pneumonia, bronchitis, quinsy, measles and many others. But besides falling ill with one of those diseases, you may hurt yourself in many other ways. You may sprain your ankle, break your leg, cut your finger of graze your knee. You may also have a nosebleed or a heart attack Quite a number of diseases are infectious. We can get these diseases from people already ill with the disease or infected food or animals. Most common infectious diseases are such children's diseases as measles, mumps, scarlet fever and chicken pox. Some diseases have become more rare because children and grown-ups can be vaccinated against them for example polio, diphtheria, smallpox. Tuberculosis (TB) was almost stamped out, but now it is returning, having become resistant to many medicines that were used to cure it years ago. The most infectious disease in the Middle Ages was plague, now AIDS has replaced it

twelve. Everyone loves the sleepy gray koalas. Like kangaroos, they have s pouch on their fronts for their babies. After six months there, baby koalas ride on their mother's back. They live in eucalyptus trees, sleeping for eighteen hours, and eating one kilo of leaves, each day. They drink almost nothing. The word koala means "no water." In the seas and rivers of northern Australia crocodiles can be found. They are five or six metres long. They eat fish, animals, kangaroos - and sometimes people. There are more than 800 kinds of birds in Australia. The emu, which is two metres tall, is the second largest bird in the world. It cannot fly at all, but it can run at fifty kilometres an hour. Then there is the kookaburra, whose cry sounds like someone laughing, and the budgerigar, a little blue or yellow bird that people keep in their homes all over the world.
