Mayan Civilisation of Central America. The disappearance of one of the great civilisations of the ancient world puzzled scientists for years, as they searched for clues among the ruined and deserted Mayan cities. How could a sophisticated culture with its knowledge of mathematics and astronomy vanish into thin air? At its height in about 800 AD, there were probably about 13 million •Mayans supporting elaborate cities with grand pyrarnid temples. Their lands extended from Chichen Itza on Mexico's Yucatan Peninsula, through Tikal in Guatemala to Copan in Honduras. And then, almost instantly, everything collapsed. Researchers have recently discovered that it was in fact climate change that caused the collapse of Mayan culture. It coincides directly with several periods of intense drought each lasting about a decade. The worst drought lasted between about 760 and 800 AD. Each one put more intense pressure on an already fragile civilisation. The cities were densely populated. But they relied on corn-growing farmers who didn't produce enough to sustain both themselves and the city dwellers. Even though the Maya built reservoirs to collect water, their crops still depended on seasonal rains. Their land had few rivers, being mostly dry limestone. When the rains failed, the water for drinking and agriculture simply ran out. With few reserves and lacking what became crucial for survival, Mayan Civilisation died. History has many examples of cultures that collapsed in other parts of the world. Almost 3,500 years ago, a drought lasting about 200 years terminated a flourishing society in Mesopotamia. Scientists know from studying the rings in trees that a drought in about 1130 AD destroyed the Anasazi culture of the Chaco Canyon in New Mexico, USA. But not all societies have had to surrender to the devastating effects of drought. The Chumash, of California's Channel Islands, apparently changed their behaviour in response to climate change. When deadly droughts threatened their survival, these hunter-gatherers became traders. What can modern societies learn from the Maya's downfall? Supplies of clean water are one of the biggest problems facing countries all over the world. Australia has experienced record droughts since the start of the 21st century. The western USA uses so much water that the Colorado River is dry by the time it joins the sea. People will have to change their habits even more, in order to survive the climate changes that are predicted in the next decades.

arteries to all the parts of the body Scientists have determined that the total weight of the blood pumped by the hemi daily is about 10 tons. Physiologists have established that in the adult the heart makes from 60 to 7,' beats per minute.4n children the rate of heartbeat is much higher. Research work of many scientists has helped to determine that the rate of heartbeat increase depending on different emotions. Each beat of the heart is followed by a period of rest for the cardiac muscle Each wave of contraction and a period of rest following it compose a cardiac cycle The period of rest is shorter during greater physical exertion and longer when the body is at rest. The physiologists called the first phase of short contraction of both atria - the atrial systole, the second phase of more prolonged contraction of both ventricles- the ventricular systole. The period of rest of the cardiac muscle is called the diastole The blood received by the left atrium from the pulmonary circulation is discharged out by the left ventricle to the systemic circulation through the aorta. The atria act as receiving chambers.

south of Australia, is small. It’s the same size as England. It is also very different from the other states. There are no deserts in Tasmania. It often rains, both in winter and summer. Only a half of million people live in Tasmania, and a large part of the island is still covered with wild, beautiful wild forests. These forests are full of wonderful flowers and interesting animals.

2. In the Northern Territory you will find the red heart of Australia. And it really is red, with red rocks, red sand, and red skies in the evening. Every year, thousands of tourists visit Ayers Rock and a strange group of huge red stones called “the Olgas”. But these places are also holy to the Aboriginals. They believe that the land itself has life.

3. Sydney is the best known place in New South Wales. In fact, it’s the best known place in Australia. But New South Wales has more than cities. There are, for example, the Blue Mountains. They are covered with forests of blue colored eucalyptus trees. The air above the forest contains millions of microscopic drops of eucalyptus oil. When the sun shines, the air of the Blue Mountains is a real, beautiful blue.
