问题     In our increasingly complex world, information is becoming the basic building block of the society. (46)However, at a time when the acquisition of new scientific information alone is approaching a rate of 250 million pages annually, the tide of knowledge is overwhelming the human capability of dealing with it. So man must turn to a machine if he hopes to contain the tide and channel it to beneficial ends.
    (47)The electronic computer, handling millions of facts with the swiftness of light, has given contemporary meaning to Aristotle’s vision of the liberating possibilities of machines: "When looms weave by themselves, man’s slavery will end." By transforming the way in which he gathers, stores, retrieves, and uses information, this versatile instrument is helping man to overcome his mental and physical limitations. (48)It is vastly widening his intellectual horizon, enabling him better to comprehend his universe, and providing the means to master that portion of it lying within his reach.
    Although we are only in the second decade of electronic date processing, the outlines of its influence on our culture are beginning to e merge. (49)Far from depersonalizing the individual and dehumanizing his society, the computer promises a degree of personalized service never before available to mankind.
    By the end of century, for the equipment of a few dollars a month, the individual will have a vast complex of computer services at his command. Information utilities will make computing power available, like electricity, to thousands of users simultaneously. (50)The computer in the home will be joined a national and global computer system that provides services ranging from banking and travel facilities to library research and medical care. High-speed communication devices, linked to satellites in space, will transmit data to and from virtually any point on earth with the ease of a dial system.

选项
答案电子计算机正大大扩大人类的知识视野，使人类能更好地了解宇宙，从而为人类能征服涉及到的那部分宇宙提供了工具。
解析 这个句子是含有两个并列分句的简单句。句子的主干是It is widening his intellectual horizon，enabling…，and providing…；分词短语enabling...和providing…是表示结果意义的状语。句中的it指代"电子计算机"，his，him都是指代"人类的，人类"，为使语义明确，须把指代的内容一一译出。句中intellectual horizon意为"知识视野"；that portion of it lying within his reach中指代the universe，意为；人类能涉及到的那部分宇宙"。两分词短语之间，按其内在的逻辑关系，增译了连词"从而"。
