[单项选择]{{B}}C{{/B}}
We were beginning to get more and more
fed up with the "holiday by the sea". We always used to go to the south coast
regularly for a fortnight every summer. There was not a chance to have a proper
summer holiday last year, so we decided we’d better have some sort of a winter
holiday. Some friends of ours told us we might not enjoy a skiing holiday, that
it was always so cold you had to go skiing just to keep warm. We only had eight
days instead of our normal fortnight a way. All together, with the return
flight, accommodation (住宿), etc. , it came to about £ 135 for the three of us.
And it was worth every penny, I mean. I work hard all the year round. I need a
complete change and I’m willing to pay for it. I’d certainly recommend a holi
day like this to anyone. We saved up for it;, by the way, by cutting down on
luxuries. |
A. It can not be a special treat.
B. It can be very cheap.
C. It can serve as a welcome change.
D. It means living without luxuries.

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 great
A. Both private employers and government employers discriminate, with equal effects on women’s earnings.
B. If private employers and government employers discriminate, the discrimination by private employers has a greater effect on women’s earnings.
C. Private employers discriminate; it is possible that government employers discriminate.
D. Private employers discriminate; government employers do not discriminate.
