David's family visited the zoo on Sunday. They paid five dollars for the family ticket at the gate. And then they joined the crowds flocking toward the cages. 'We must watch the big animals first,' said the father. 'Feeding time is three o'lock.' 'Let's look at the birds first,' said Susan. 'Some of the parrots can talk very well.' Soon they came to the bird house, and the first bird they saw was talking. Then they moved through the house, and came to a lake. David said, 'Those big white birds in the water have such long necks. Look how gracefully they swim.' In the next house, a great roar told them that they had been lucky enough to arrive at feeding time. As they went in, they saw tigers and lions were howling because they were hungry. 'We'll see how they eat,' said father.
