听力原文:M: (22) Today, we invite Ms. Linly-n from International Labor Organization. If one looks in this report, I suppose one should be surprised by the conclusions. But haven't we heard it all before?
W: For some women, there has been definite progress. Some women have breached the glass ceiling-they have entered previously male-dominated occupations, (23) but for the majority the increase in the number of opportunities of employment have not been matched by improvements in the quality of the working conditions, in remuneration that they're receiving.
M: What... what... let's explain something to the industrial on the developing countries when we look at the industrial on G 7 and LODC countries, what's the plight there?
W: We take the total work load which includes both paid and unpaid work then the differences are not so great. For instance, if we take the United States, then in fact, men work for 59 hours a week, women work 56 hours. (24) But we take just unpaid work which will be like preparing food, taking care of children and other house- work, then women do two thirds of all unpaid work as compared to one third done by men.
M: In developing countries, isn't that a real problem that of very low pay for women in the workforce?
W: (25) Not just a question of very low pay, but also a question of a woman needing to increasingly work to enable poor families to survive, and also the very much longer hours they work. For instance, in many developing countries, in Africa, for instance, women work 31 to 42 hours in unpaid work as compared to 5 to 15 hours done by men.
