Women’s role in society has gone through major changes in recent years. What exactly are the roles women should play in society? Some people say they should stay at home, raising children and taking care of their husbands. Some people argue that the only careers women can choose are as nurses, teachers and secretaries because they are the most suitable for them. As a matter of fact, women in a modern society are playing more and more important roles. They can be, in addition to those traditional careers, astronauts, scientists, politicians, entrepreneurs and so on. They are doing what men are doing now. The concept that women hold up half the sky is generally accepted. Though, in some countries, after giving birth to a baby a woman might stay at home and bring up the child, she tends to go back to work after the child is independent. Women in many countries are an indispensable labor force in the present world.
