Questions are based on the following passage.
　　I don't ever want to talk about being a woman scientist again. There was a time in my life when people askedconstantly for stories about what it's like to work in a field dominated by men. I was never very good at telling thosestories because truthfully I never found them interesting. What I do fred interesting is the origin of the universe, theshape' of space-time and the nature of black holes.
　　At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in theclassroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started tobother me. My every achievement--jobs, research papers, awards--was viewed through the lens of gender (性 别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain.versus (相对于)fight brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.
　　Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply toany and all provocations: I don't falk about that anymore. It took me 10 years to get back the confidence I had at 19and to realize that I didn't want to deal with gender issues. Why should curing sexism be yet another terrible burdenon every female scientist? After all, I don't study sociology or political theory.
　　Today I research and teach at Barnard, a women's college in New York City. Recently, someone asked mehow many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer:45. I know some 9fmY students worry how they will manage their scientific research and a desire for children. AndI don't dismiss those concerns. Still, I don't tell them "war" stories. Instead, I have given them this: the visual oftheir physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of45 women driven by a love of science. And that's a sight worth talking about.
