5.The family      on time,but their car had a flat tyre on the halfway.(  )
A.would arriveB.could arrive
C.must have arrivedD.would have arrived

分析 这一家人本可以按时到达的,但是半路上他们的轮胎漏气了.

解答 答案:D.
根据句意"半路上他们的轮胎漏气"可知,此处表示对过去情况的虚拟,故谓语动词用could/would/should/might have done,故选D.

点评 与过去事实相反的情况,从句中谓语用had done,主句谓语用would have done.本句中的but引导的句子属于过去的事实,只需要前面的句子用虚拟语气即可.

I don’t ever want to talk about being a woman scientist again. There was a time in my life when people kept asking me stories about what it’s like to work in a field under the control of men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the existence of the universe, the shape of space time and the nature of black holes.

At 19, when I began studying astrophysics(天体物理学), 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 problem started to bother me. My every achievement—jobs, research papers, awards—was viewed from the angle of gender (性别) politics. So were my failures.

Then one day a few years ago, out of my mouth came a sentence that would finally become my reply to any and all provocations(挑衅): I don’t talk about that any more. 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 problems. Why should removing 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 take no notice of those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the scene of their physics professor heavily pregnant (怀孕)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.
