     Mr. Ellis is very old. He has seen many changes in his home town.   

     He knows that things are different now. But he never forgets the old days. He likes to talk about them. He

often talks about his favourite (最喜欢的) birds, the robins (一种小小鸟--鸫). "When I was a boy, these houses were not here. There were wide fields and tall trees. Every spring robins would come. Thousands of them

would fly up to the north from the south. They spent the winter in the south. Some would build their nests (巢)

in the trees near our houses. Then people started to cut down trees, and they built more houses. The robins

stopped coming. They couldn't build their nests near our houses because there were no trees."

any more (不再)."
