Read the text and mark the sentences T (true) or F (false). Thanksgiving Day. Thanksgiving Day is the most popular American national holiday. In XV century European people wanted to trade with China. But the way to China was too dangerous and expensive. That's why Christopher Columbus wanted to find a new route to this country. He didn't find new way, but in 1492 he opened New World (now it's North America). A lot of people came to the New World for different reasons: trade; freedom of religion; the freedom of politician; and some economic reasons. The first colonies appeared in Virginia in 1607 along the eastern coast of North America. In 1620 the first group of pilgrims came to the New World. They came there too late so they couldn't get good crops. That's why, more then half of them died in the first winter. Next year the people who lived in America - Indians, taught the pilgrims how to survive there. They showed them a lot of new kinds of food: potato, corn. Indians taught the pilgrims how to hunt, fish, get a good harvest. That year people got a great harvest, and they called their friends - Indians, and gave them their thanks with a huge dinner. So in 1621 was born a new American national holiday - Thanksgiving Day. Now it's celebrated on the 4th Thursday of November. On this day everyone comes to the house of his parents and they have a great Thanksgiving dinner. E.g. Thanksgiving Day is an English national holiday. __F__ 1.
