Ребята нужна ваша помощь!!! Перевести текст со словарем, ответить на вопросы The Buffalo The buffalo is the largest North American animal. It weighs as much as 2,000 pounds. It lives with other buffalo in groups or herds. Two hundred years ago, there were 60 million buffalo. They lived all over the centre of North America. There were thousands of herds. One herd was twenty miles long and twenty miles wide. The buffalo followed the grass and the Indians followed the buffalo. The Indians used the buffalo for many things. They used it for meat. Sometimes they ate fresh meat. Sometimes they dried the meat in the sun. Then they ate it later. The Indians also used the skin, or hide, of the buffalo. From the hide they made tents, clothes, shoes, hats, and rope. They wasted nothing. But times changed. People from other lands came to America. These immigrants crossed the country in wagon trains.They killed the buffalo for food and hides. More and more people came. And everyone wanted leather. Hunters with guns killed the buffalo only for their hides. They wasted everything else. These hunters were very good at their job. By 1900, there were fewer than thirty buffalo alive. Today, there are about 30,000 buffalo in America. But herds are very small. You can see them in states like Wyoming. Sometimes you can buy buffalo meat at a restaurant. But you will never see a herd of buffalo as big as a city. Questions: The buffalo is the largest North American animal, isn’t it? How many buffalos were there two hundred years ago? How many buffalos are there today in America? What did Indians use the buffalo for? Can you buy buffalo meat at a restaurant?
