My uncle has been in America for quite a few years. He used to live in Pudong. He wanted to come back to his homeland very much. I~ast summer he came to Shanghai and I took him to visit Pudong. He said the streets became wider and the buildings became higher. I told him, Many people have moved into new and big flats. It is very convenient to go shopping here. He couldn＇t find his old house. He said, What GREat changes! He decided to stay and spend the rest of his life in Shanghai.
