TASK I. READING. Read the text. Write "TRUE" or "FALSE". Correct the false sentences.
тут 3 текста !!!
1) Every day, species around the planet are becoming endangered because of climate change and human activities. Some animals, like the snow leopard, the saiga antelope, the steppe eagle and the Caspian seal, are so critical that they are threatened with extinction. Others have already become extinct, like Caspian tiger, the cave lion, the aurochs and the Siberian unicorn During the Ice Age, herds of mammoths, steppe bison and Hyperion horses wandered the steppes of Central Asia, but they all disappeared thousands of year ago. So, what exactly happened to these animals? And how do we even know they existed or what they looked like? ВО 781

2) Paleontologists are scientists who study the fossils of plants and animals that lived long ago. They have found evidence that there was a global extinction of very large mammals at roughly the same time when humans expanded around the world. And many scientists believe that the two events are connected. Mammoths and steppe bison were hunted by prehistoric humans for food, for their fur and their bones. The fur was used for making clothes and the bones were used for making tools, weapons, decorations and even houses. Fossils aren't the only evidence in support of this theory. Prehistoric people painted pictures of hunting scenes with mammoths, bison and other animals on cave walls and rocks around the world.

3) Another theory is that mass extinction wasn't caused by hunters but by changes in the environment. Towards the end of the last Ice Age about 15,000 years ago, the weather started to change and the larger mammals couldn't adapt to the higher temperatures. Many of them lost their habitats and migrated north, where they died because they couldn't find enough food. Scientists have discovered numerous fossils of mammoths and other prehistoric animals in Siberia and the Arctic. They are hoping that by using DNA from theses fossils, we could one day clone a mammoth.

(назвать" правду неправду " и почему?
1) The Caspian tiger and the aurochs are endangered animals.
2) Thousands of years ago, there were mammoths in Central Asia.
3) Paleontologists are artists who draw pictures of extinct species.
4) Prehistoric people sometimes made tools from the bones of the animals they hunted.
5) About 15,000 years ago, many large mammals died because of the cold weather.
6) Scientists might clone a mammoth on day.
