Read the following passage, then choose the correct answer A. B, C or D. Women nowadays have more advantages than those in the past. For example, our great grandmothers were not allowed to go to school or go to work or even choose their own husband. As a result, they had to depend on their husbands. Modern women, on the contrary, can get good education, have their own careers, and pursue their interests. However, women living in our modern society have their problems, too. Today’s women work harder than their great grandmothers so that they can gain the balance between working life and family life. Many people predict that by 2032, most senior positions at work will be taken by women. Then, it is possible that women will have more strenuous life because, even in a very modern society, the women can’t neglect their role in the family. 1. In the past, our great grandmothers were not allowed to ________. A. go to school B. go to work C. choose their own husbands D. All are correct 2. Why do women now work harder than their great grandmothers? A. Because they get good education. B. Because they live in modern society. C. Because they have to gain the balance between working life and family life. D. Because they have their own careers. 3. Which of the following sentences is NOT TRUE about women in the future? A. They will take most senior positions at work. B. They don’t have to worry about any things. C. They will have strenuous life. D. They can’t neglect their role in the family. 4.
