Gender Gap

The girls in this sixth grade class in East Palo Alto, California, all have the same access to computers as boys. But researchers say, by the time they get to high school, they are victims of what the researchers call a major new gender (性别) gap in technology. Janice Weinman of the American Association of University Women says, "Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information."＜br＞

After re-examining a thousand studies, the American Association of University Women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom.＜br＞

An instructor of a computer lab says he&39;s already noticed some differences. Charles Cheadle of Cesar Chavez School says, "Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow."＜br＞

Six years ago, the software company Purple Moon noticed that girls&39; computer usage was falling behind boys. Karen Gould says, "The number one reason girls told us they don&39;t like computer games is not that they&39;re too violent, or too competitive. Girls just said they&39;re incredibly boring."＜br＞

Purple Moon says it found what girls want, characters they can relate to and story lines relative to what&39;s going on in their own lives. Karen Gould of Purple Moon Software says, "What we definitely found from girls is that there is no intrinsic (固有的 ) reason why they wouldn&39;t want to play on a computer; it was just a content thing."＜br＞

The sponsor of the study says it all boils down to this: the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21 st century.

when people asked constantly for stories about what it's like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-lime 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 the classroom. But while earning my Ph. D. at MIT and then as a post-doctor doing space research, the issue started to bother 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) right 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 month came a sentence that would eventually become my reply to any and all provocations: I don't talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn't want to deal with gender issues. Why should curing sexism be yet another terrible burden on 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 me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don't dismiss those concerns. Still, I don't tell them "war" stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that's a sight worth talking about.

Why doesn't the author want to talk about being a woman scientist again？

A．She feels unhappy working in male-dominated fields.

B．She is fed up with the issue of gender discrimination.

C．She is not good at telling stories of the kind.

D．She finds space research more important.

Passage Two

I don’t ever want to talk about being a woman scientist again. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape 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 the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother 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) right 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 to any and all provocations: I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on 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 me how may of the 45 students in my class were women.
