翻译原文:The most intuitive development of Boolean algebras arises from the concept of a set algebra. Let S={a, b, c} and T={a, b, c, d, e} be two sets consisting of three and five elements, respectively. We say that S is a subset of T, since every element of S (namely, a, b, and c) belongs to T. Since T has five elements, there are 25 subsets of T, for we may choose any individual element to be included or omitted from a subset. Note that these 32 subsets include T itself and the empty set, which contains no elements at all. If T contains all elements of concern, it is called the universal set. Given a subset of T, such as S, we may define the complement of S with respect to a universal set T to consist of precisely those elements of T which are not included in the given subset.
翻译答案:布尔代数最直觉的发展产生于集合代数的概念。设S={a,b,c}和T={a,b,c,d,e}分别为两个含有三个和五个元素的集合。由于S中的每一个元素(a,b,c)都属于T,所以我们说S是T的一个子集。由于T有五个元素,因而T共有25个子集,这是因为我们可以选择任何一个元素使其包含于某个子集中或从该子集中删除。应该注意到这32个子集中包含T本身和空集(空集即不含任何元素的集合)。如果T包含了所讨论的所有元素,则称之为全集。给定T的一个子集,例如子集S,我们可以定义一个关于全集T的S的补集。其中正好包含那些不在子集S中而在T中的元素。
读完一本书翻译原文:‘And now, comrades, I will tell you about my dream of last night. I cannot describe that dream to you. It was a dream of the earth as it will be when Man has vanished. But it reminded me of something that I had long forgotten. Many years ago, when I was a little pig, my mother and the other sows used to sing an old song of which they knew only the tune and the first three words. I had known that tune in my infancy, but it had long since passed out of my mind. Last night, however, it came back to me in my dream. And what is more, the words of the song also came back — words, I am certain, which were sung by the animals of long ago and have been lost to memory for generations. I will sing you that song now, comrades. I am old and my voice is hoarse, but when I have taught you the tune, you can sing it better for yourselves. It is called Beasts of England.’
翻译答案:“现在,同志们,我来谈谈关于昨晚那个梦的事。那是一个在消灭了人类之后的未来世界的梦想,我无法把它描述出来。但它提醒了我一些早已忘却的事情。很多年以前,当我还是头小猪时,我母亲和其他母猪经常唱一只古老的歌,那支歌,连她们也只记得个曲调和头三句歌词。我很小的时候就对那曲调熟悉了。但我也忘了很久了。然而昨天 晚上,我又在梦中回想起来了,更妙的是,歌词也在梦中出现,这歌词,我敢肯定,就
是很久以前的动物唱的、并且失传很多代的那首歌词。现在我就想唱给你们听听,同志们,我老了,嗓音也沙哑了,但等我把你们教会了,你们会唱得更好的。他叫‘英格兰兽’。”
