AB和CD是完全相同的两条带有绝缘皮的导线，它们并行地埋设在相距2km的甲、乙两地之间．由于两导线之间某处的绝缘外皮受到损伤，而发生了漏电现象（即相当于两根导线之间在漏电处连接了一个电阻．为了确定漏电处的位置，维修人员做了以下测量：

（1）在甲地将两端电压恒为90V的电源的两极分别接在A、C两端，此时在乙地用内电阻很大的电压表测得B、D两端电压为72V．

（2）在乙地将两端电压恒为100V的电源的两极分别接在B、D两端，此时在甲地用同一型号的电压表测得A、C阳端的电压为50V．

如果AB和CD导线每千米电阻值为2Ω，请你根据以上测量结果计算漏电处距甲地多远？绝缘皮破损处的漏电电阻是多大？

Sex prejudices are based on and justified by the ideology(意识形态) that biology is destiny. According to this ideology, basic biological and psychological differences exist between the sexes. These differences require each sex to play a separate role in social life. Women are the weaker sex both physically and emotionally. Thus, they are naturally suited, much more so than men, to the performance of domestic(家庭的) duties. A woman’s place, under normal circumstances, is within the protective environment of the home. Nature has determined that women play caretaker roles, such as wife and mother and homemaker. On the other hand, men are best suited to go out into the competitive world of work and politics, where serious responsibilities must be taken on. Men are to be the providers; women and children are “dependents”.

The ideology also holds that women who wish to work outside the household should naturally fill these jobs that are in line with the special capabilities of their sex. It is appropriate for women, not men, to be employed as nurses, social workers, elementary school teachers, house-hold helpers, clerks and secretaries. These positions are simply an extension of women’s domestic role. Informal distinctions between “women’s work” and “men’s work” in the labor force, according to the ideology, are simply a functional reflection of the basic differences between the sexes.

Finally, the ideology suggests that nature has worked her will in another significant way. For the human species to survive over time, its members must regularly reproduce. Thus, women must, whether at home or in the labor force, make the most of their physical appearances.

So goes the ideology. It is, of course, not true that basic biological and psychological differences between the sexes require each to play sex-defined roles in social life. There is enough evidence that sex roles vary from society to society, and those role differences that do exist are largely learned.

But to the degree people actually believe that biology is destiny and that nature intended for men and women to make different contributions to society, sex-defined roles will be seen as totally acceptable.
