问题     Electronics(电子学) is the technology which marshals and controls electrons in materials, and today its applications seems to be boundless. The most striking application recently was the establishment of an electronic communications web around the world to make the moon landing possible. In the near future this web or a similar one will be used in a survey of the earth’s resources. (46)Satellites will not only record interesting geographical features but will be of invaluable service in reporting on outbreaks such as insect plague, plant disease, bush fire, and volcanic activity.
    Electronics is also the key to automation, where manual control of machines is replaced by electronics controls which are faster, and more accurate and reliable. (47)The automatic timing of traffic lights, the automatic mining and processing of ores(矿石) the numerical control of machine tools, the control of electrical power stations, the automatic monitoring of hospital patients’ medical conditions, and the monitoring of plant and animal growth ate all examples of the rapidly growing applications of electronics in this area.
    (48)Apart from automation, other applications which arouse public opinion include satellites used for military purposes, electronic bugging systems and computer centers to record personal data on all citizens. As well as providing the nucleus for such data centres, computers will take over more and more of the routine operations of modem life. They seem destined to be the application of electronics which will have most influence on our lives in the coming decade. (49)Perhaps more significantly in the long-range view, they will extend man’s reasoning power as tools and machines have extended his muscles in the past and the telephone, radio, and TV are extending his senses at present.
    (50)Since electronics is used in so many activities and because it touches on many other subjects, it provides possible means of con tact between engineering and the social, natural and medical sciences.

选项
答案由于电子学用于这么多方面，并且涉及到许多其它学科，它为工程学和社会科学、自然科学与医药科学之间提供了可能的联系手段。
解析 本句采用"减译法"、"重译法"翻译。此句是一个主从复合句，主句的主干是....it provides possible means of contact.....，连词since和because分词引导两个并列的原因状语从句。句中activities本意为"活动，活跃"。这里转义为"方面"，touch on意为"涉及"。由于since与because都表示原因，为使语义简洁，特减译为一个；同时，为了使意义明确，将(social，natural，medical)science重复译两次。
