Passage 18

It seems quite clearly unjust to pay two people different amounts of money for doing the same work.But it is not as easy as it appeals at first __21__ to introduce equal pay for equal work..似乎很清楚的不公正，人支付不同数额的金钱做同样的工作。但它并不容易，因为在第一眼来介绍同工同酬。

Two people may be working side by side in a factory and doing the same work,but one may be doing it twice as fast as the __22__;or one may be making no mistakes,while the other is making a lot.In some kinds of work,one can solve the problem of speed if one pays by the amount of work to be done and not by the hour:work paid for in this __23__ is called piece-work.But it is not always possible to do this,so it is sometimes useful to pay workers at different rates,which take differences in skill into __24__.This usually means that the younger and therefore less experienced worker gets less than the __25__ and more experienced one,which seems reasonable enough.

两个人可能并排在一个工厂工作，做同样的工作，但一个可以比另一个做快一倍的工作；或可能是一个不犯错误，而另一个犯很多错误。在某些种类的工作中，一个可以解决问题，如果你的工作是靠工作的数量来付钱的，而不是以小时来计算的工作方式。这叫计件工。但它并不总是可能做到这一点，所以有时是以工人的不同的速度来计酬劳是很有用的，就是把技能的差异考虑进去。这通常是指年轻和缺乏经验的工人得到的酬劳低于年老的和更有经验的人，这似乎很合理。

One thing that man can do is to limit the __23__ of babies born.The need __24__ this is obvious,but it is not __25__ to achieve.People have to be persuaded to limit their families.人们唯一可以做的是，限制出生的婴儿的数量。需要这么做是显而易见的，但它不是容易实现。人们不得不被说服，来限制他们的家人。
