Task 1. How much physical activity do you think a young person needs to stay healthy? Read and check your answers. What are the activity intensity levels? When you take part in a low-intensity activity, you do not sweat and your breathing is not affected greatly. Moderate-intensity activities should make you sweat and your heart beat faster. You cannot sing, but you can continue talking. As for high-intensity activities, you start to sweat sooner and cannot talk without getting out of breath.
Physical activity is any activity where you move your body and burn energy. There are many benefits of being physically active. Firstly, exercise stops you from becoming overweight, and this is important because keeping a healthy weight lowers your risk of developing certain illnesses in the future. What is more, when you work out, play a sport or even just go for a walk, the muscles and bones in your body become stronger. Because your heart is a muscle too, physical activity can keep it strong and healthy. You definitely want it to be strong enough to send blood and oxygen around your body!
We should all take part in physical activity regularly. According to the World Health Organization, young people aged between 5 and 17 should do about 60 minutes of moderate to high-intensity physical activity daily to keep their heart healthy and to stay fit. This does not have to be done all at once but can be done throughout the day.

Pacific ocean — the largest and most ancient of all the oceans. Its area is 178,6 million km2. It is free to hold all the continents and Islands together, so it is sometimes called the Great. The name "Quiet" associated with the name of F. Magellan, performed a world tour and passing through the Pacific ocean under favorable weather conditions. This ocean is really great: it takes up 1/3 of the surface of the planet and almost 1/2 of the World's oceans. The ocean has an oval shape, it is especially wide at the equator. The peoples inhabiting the Pacific coast and the Islands, have long been sailing on the ocean, explore its riches. Information about the ocean have been accumulated as a result of the voyages of Magellan, F., J. Cook. The beginning of a wide study was initiated in the XIX century the first Russian circumnavigation expedition of I. F. Kruzenshtern. Currently, there is a special international organization for the study of the Pacific ocean. In recent years new data on its nature, defined depth, study of currents, bottom topography, biological resources of the ocean. The southern part of the ocean from the coast of the Islands of the Tuamotus to the coast of South America is an area of calm, light winds and stable atmosphere. It is for this peace and quiet, Magellan and his companions called the Pacific ocean. But to the West of the Islands of Tuamotus, the picture changes dramatically. Calm weather is rare here, usually blow stormy winds, often developing into hurricanes. This so-called squalls South Australia, especially fierce in December. Less frequent but more intense tropical cyclones. They arrive in early fall from the Coral sea, near the Northern tip of New Zealand they move to the warm West winds. Так?
Horse. The story of the horse begins 65 million years ago. With a small similar to a small dog of Eohippus, with flexible ecobraze curved spine and a long tail. The next link in the evolution of the horse - hipparion, which resembled a small fleet-footed gazelles. For a long time horses were used only as a productive animal. Appearance: a Healthy horse, always cheerful and lively, actively and quickly respond to external stimuli. I think horses are the most graceful animal in the world. ( Перевод: Лошадь.История лошади начинается 65 млн лет назад. С маленького, похожего на небольшую собачку эохиппуса, с гибким аркообразно изогнутым позвоночником и длинным хвостом. Следующее звено эволюции лошади - гиппарион, который напоминал небольших быстроногих газелей. Долгое время лошади использовали лишь как продуктивное животное. Внешний вид: Здоровая лошадь, всегда веселая и подвижная, активно и быстро реагирует на внешние раздражители. Я думаю, что лошадь - это самое грациозное животное на свете.)
