[单项选择]In a perfectly free and open market economy, the type of employer -- government or private -- should have little or no impact on the earnings differentials between women and men. However, if there is discrimination against one sex, it is unlikely that the degree of discrimination by government and private employers will be the same. Differences in the degree of discrimination would result in earnings differentials associated with the type of employer. Given the nature of government and private employers, it seems most likely that discrimination by private employers would be greater. Thus, one would expect that, if women are being discriminated against, government employment would have a positive effect on women’s earnings as compared with their earnings from private employment. The results of a study by Fuchs support this assumption. Fuchs’s results suggest that the earnings of women in an industry composed entirely of government employees would be 14. 6 percent greater than the earnin

the big old house in which I had spent my whole life. Each time I thought of
that, I felt very sad. When the final day came, I ran to a corner and sat alone,
trying not to let others see my tears. Suddenly I felt a hand patting me on the
shoulder. I looked up, and saw my grandpa. "It isn’t easy, is it, my grandson"
he said in a very low voice, sitting down beside me. I nodded through my tears,
without a word. We sat silently for a long time. Then he said, "Good-by is such
a sad word that it seems too cold for us to use. We must try to avoid
it."
Then we walked slowly in the garden, hand in hand, to have
a last look at each rock, each tree, each flower. We sat for a while by the
small pond which was a favorite place of my grandpa’s. "What do you see here,
Tommy" asked the old man. I looked at the wat

It is hard to predict how science is
going to turn out, and if it is really good science it is impossible to predict.
If the things to be found are actually new, they are by definition unknown in
advance. You cannot make choices in this matter. You either have science or you
don’t, and if you have it you are obliged to accept the surprising and
disturbing pieces of information, along with the neat and promptly useful
hits,
The only solid piece of scientific truth abut which I feel
totally confident is that we are profoundly ignorant about nature. Indeed, I
regard this as the major discovery of the past hundred years of biology. It is,
in its way, an illuminating piece of news. It would have amazed the brightest
minds of the 18th. century Enlightenment to
