Animals grow up in different ways. They have lots of lessons to learn.   Some animals are born helpless but their mothers protect them. A newborn kangaroo is the size of a bee. She stays in her mother’s safe pouch. She doesn’t open her eyes for at least five months. A newborn monkey cannot walk. He is carried by his mother. Other baby animals can walk soon after they’re born. They learn to run with their mother when danger is near. A baby zebra（斑马）can run an hour after she is born. Some baby animals are born in a place that is safe. Other baby animals are born in the open. Baby wolves are born in large holes. A baby elephant is born on open, grassy land. Other elephants make a circle（圈）to protect her. Animals that drink their mothers’ milk are called mammals. A mother bear’s milk is fatty and rich. Baby bears need lots of fat to keep warm in winter. They have milk for six months. Baby zebras drink milk for six months or more! As baby animals grow they need solid（固体的）food. Baby lions eat what their mother can catch. 小题1:Which baby animals don’t open their eyes for at least five months?
