阅读理解Greatchangeshavebeenmadeinfamily

阅读理解 Great changes have been made in family life because of science and industry. In the past, when more Americans lived on farms, the typical family had many children. In a farm family, parents and their children often lived with grandparents. Often, too, uncles and aunts lived nearby. But when industry becomes more important than agriculture in American life, families become smaller because industry requires workers who are ready and able to move off the land and to move again whenever necessary. And large families cannot be moved from place to place as easily as smaller families can. So , at present people tend to have smaller families. In the future, because of industrialization, a typical family will be required to move even more often than now, so families will be even smaller. The typical families may remain childless and are only made up of a man and a woman. A small number of families may take raising children as their chief work. At the same time they may also raise other people’s children, leaving those families free to move job to job.1.The main topic discussed in the passage is _______.
