[单项选择]Although the women’s rights movement in the United States is thought of as a recent development, its beginnings date back over one hundred and seventy years. At that time women were dependents in the eyes of the law, and they did not have the rights of adults. A woman had no property rights, even over what she had got it from her mother or father or over any wages that she earned. Decisions about family matters and about the children were made by her husband, the "head of the family".
The first public protests (请愿) against the low position of women were made in the 1830s. In 1848 the leaders of this movement (some of whom were for antislavery (反对奴隶制) activities as well) assembled the first Women’s Rights Convention, demanding equality. In this struggle as well as in the long, hard fight for women’s vote, those who took part in the activities were laughed at and insulted (侮辱). They were said to be immoral (违反伦理的), and their ideas were considered dangerous to society.
