翻译原文:The situation is complicated by the fact that the procedure may itself request the execution of another procedure, which may request still another, and so on (Figure 7.9). Consequently, the return locations being remembered begin to pile up. Later, as each of these procedures is completed, execution must be returned to the proper place within the program unit that called the completed procedure. A system is therefore needed to save the return locations and later retrieve them in the proper order.
翻译答案:如果一个被调用的过程本身还要调用其他过程,而那些过程同样也需要调用另外的过程,这样一来整个情形就会很复杂。因此,返回地址的记忆就开始堆积。然后,当每一个过程都结束后,操作必须返回到被称为完成过程的程序块中的合适位置。因此,系统需要按照适当的顺序存储和找回返回地址。
读完一本书翻译原文:How they toiled and sweated to get the hay in! But their efforts were rewarded, for the harvest was an even bigger success than they had hoped. Sometimes the work was hard; the implements had been designed for human beings and not for animals, and it was a great drawback that no animal was able to use any tool that involved standing on his hind legs. But the pigs were so clever that they could think of a way round every difficulty. As for the horses, they knew every inch of the field, and in fact understood the business of mowing and raking far better than Jones and his men had ever done. The pigs did not actually work, but directed and supervised the others. With their superior knowledge it was natural that they should assume the leadership. Boxer and Clover would harness themselves to the cutter or the horse-rake (no bits or reins were needed in these days, of course) and tramp steadily round and round the field with a pig walking behind and calling out ‘Gee up, comrade!’ or ‘Whoa back, comrade!’ as the case might be. And every animal down to the humblest worked at turning the hay and gathering it. Even the ducks and hens toiled to and fro all day in the sun, carrying tiny wisps of hay in their beaks. In the end they finished the harvest in two days’ less time than it had usually taken Jones and his men. Moreover, it was the biggest harvest that the farm had ever seen. There was no wastage whatever; the hens and ducks with their sharp eyes had gathered up the very last stalk. And not an animal on the farm had stolen so much as a mouthful.
翻译答案:收割牧草时,他们干得多卖力!但他们的汗水并没有白流,因为这次丰收比他们先前期望的还要大。
这些活时常很艰难:农具是为人而不是为动物设计的,没有一个动物能摆弄那些需要靠两条后腿站着才能使用的器械,这是一个很大的缺陷。但是,猪确实聪明,他们能想出排除每个困难的办法。至于马呢,他们对这些田地了如指掌,实际上,他们比琼斯及其伙计们对刈草和耕地精通得多。猪其实并不干活,只是指导和监督其他动物。他们凭着非凡的学识,很自然地承担了领导工作。鲍克瑟和克拉弗情愿自己套上割草机或者马拉耙机(当然,这时候根本不会用嚼子或者缰绳),迈着沉稳的步伐,坚定地一圈一圈地行进,猪在其身后跟着,根据不同情况,要么吆喝一声“吁、吁,同志!”要么就是“喔、喔,同志!”在搬运和堆积牧草时,每个动物无不尽力服从指挥。就连鸭子和鸡也整天在大太阳下,辛苦地用嘴巴衔上一小撮牧草来来回回忙个不停。最后,他们完成了收获,比琼斯那伙人过去干的活的时间提前了整整两天!更了不起的是,这是一个庄园里前所未有的大丰收。没有半点遗落;鸡和鸭子凭他们敏锐的眼光竟连非常细小的草梗草叶也没有放过。也没有一个动物偷吃哪怕一口牧草。 翻译篇(每次翻译的量都不会很大,全部翻译才有奖励哦)
