В смешанных лесах растут и лиственные, и хвойные деревья.
У хвойных деревьев хвоя неодинаковая. У ёлки иголки короткие и жёсткие. У сосны они более длинные и мягкие, а у лиственницы совсем мягкие, ласковые.
Среди лиственных деревьев выделяются берёзы: они белоствольные. А дубы и клёны можно отличить по их резным листьям.
Смешанные леса очень красивы осенью, когда в зелени хвойных деревьев пестрят яркими красками клёны, осины, берёзы.

WALT DISNEY’S WORLD I think you know the name of Walt Disney. To many people in our century his name means the world of cartoons. Disney has created a lot of short cartoons and many longer films. His name is very famous, and not only in America. Walt Disney was born in Chicago on December 5, 1901. Then his family left that city in the North of America for a place in the South. When Walt Disney grew up, he began to draw pictures and create cartoons, and one day he had an idea to make a mouse the main character of the cartoons. He told his wife, Lidia, about this mouse character as a funny friendly little thing, who could speak, dance and sing and who in fact, could live like a man. “That’s a good idea,” Lidia said. “Call him Mickey.” So that is what Disney called him. In 1928 the audience saw Mickey Mouse on the screen for the first time. Mickey became very popular and soon Walt Disney and Mickey Mouse were famous stars. Then came other characters: Donald Duck, Pluto, and many, many more. Some of them are bright, some are not, but all of them are usually kind and friendly. And Disney’s main characters are always clever. In fact Disney has created a special animal world full of optimism and success. Disney’s stories end happily. All his films are easy and nice to watch. People always enjoy his cartoons very much. One day an idea came to Disney. He wanted to create a special place, a special land for children and parents to have fun together. So he built Disneyland. Disneyland is in California near Los Angeles.
