Language points 第八单元 The Development of Paging System 1.本篇课文涉及无线寻呼技术，题目可译为：寻呼系统的发展。 Any communication system which can provide customers with means to communicate from any place ,at any time and at any distance gives social and economic advantages. 分析：which引导的是一个定语从名修饰communication system.本句主语为communication system，谓语是gives .which 引出定语从句，用以修饰communication system.句中的from any place ,at any time和at any distance 三个部分是并列的。 2.语句：Urgent communications (police ,firemen ,hospitals, etc.) which could not be established because of no reply at one end of the link could have dramatic consequences if the delay in response is too long or if the call remain unanswered). 分析：本句谓语为could have ,which 引出定语从句以修饰主语Urgent communications.句中的连词or 连接两个由if 引出的状语从句。 语句：Paging solutions to the above communication situations were introduced in the first half of this century by means of simple optical and acoustical signaling devices installed on the premises of enterprises ,hospitals ,offices ,etc . 分析：主语是paging solutions,谓语是were introduced .过去分词installed作devices的后置定语。 语句:Such a signal meant that the person concerned had to call the switchboard operator immediately for instructions from the closest telephone. 分析：主语是developing paying service ,过去分词defined ,designed 修饰主语，本句因主语太长了，为避免头重脚轻，故采用了倒装结构。 语句：Thus was born a new ,but perpetually developing paging service defined as a one-way selective signaling system without speech and designed as an extension of the telephone network. 分析：本句主语是developing paying service ,过去分词defined ,designed 修饰主语。本句因主语太长了，为避免头重脚轻，故采用了倒装结构。 语句：The unquestionable success of the first generation of paging systems using wired networks with signaling devices was followed in the early 1950s by technological progress in the miniaturization of electronic circuitry. 分析：本句中using wired networks 这一现在分词短语作定语，相当于which/that use wired networks 。相同的用法还有本段的下一句，及para4的1st sentence. To obtain a two-way system would require the use of portable mobile telephones, such as terrestrial cellular packet radio systems, which are presently gaining popularity in networks. 分析：which 引导一个非限定性定语从句，修饰systems。句中the use of portable mobile telephones 意为“使用便携式移动电话”。这种“n+ prep. +n.”的结构有动词的意义。 IV.
