As families move away from their stable community, their friends of many years, their extended family relationships, the informal flow of information is cut off, and with it the confidence that information will be available when needed and will be trustworthy and reliable.
主体句式：The informal flow of information is cut off.
结构分析：本句的开头是一个用as引导的状语从句。后面的主句中包含了两个以and连接的并列分句。其中第二个分句在形式上只是一个名词性词组，其中confidence后面带了一个that引导的同位语从句。with it 中的it指代的是前半个分句中的"the informal flow of information is cut off"，with it 作为状语放在了该句子的开头，以防止头重脚轻。
Coupled with the growing quantity of information is the development of technologies which enable the storage and delivery of more information with greater speed to more locations than has ever been possible before.
主体句式：Coupled with the growing quantity of information is the development of technologies.
结构分析：本句是一个倒装句，其中表语"Coupled with the growing quantity of information"提到了主语"the development of technologies"的前面，谓语是系动词is。主语后面的which引导的定语从句修饰technologies，其中还包含了一个比较的结构。之所与将句子进行到装，是因为主语的内容太长，为了强调其内容，而将其置后。
In such a changing, complex society formerly simple solutions to informational needs become complicated. Many of life's problems which were solved by asking family members, friends or colleagues are beyond the capability of the extended family to resolve. Where to turn for expert information and how to determine which expert advice to accept are questions facing many people today.
In addition to this, there is the growing mobility of people since World War Ⅱ. As families move away from their stable community, their friends of many years, their extended family relationships, the informal flow of information is cut off, and with it the confidence that information will be available when needed and will be trustworthy and reliable. The almost unconscious flow of information about the simplest aspects of living can be cut off. Thus, things once learned subconsciously through the casual communications of the extended family must be consciously learned.
Adding to societal changes today is an enormous stockpile of information. The individual now has more information available than any generation, and the task of finding that one piece of information relevant to his or her specific problem is complicated , time-consuming and sometimes even overwhelming .
Coupled with the growing quantity of information is the development of technologies which enable the storage and delivery of more information with greater speed to more locations than has ever been possible before. Computer technology makes it possible to store vast amounts of data in machine-readable files, and to program computers to locate specific information. Telecommunications developments enable the sending of messages via television, radio, and very shortly, electronic mail to bombard people with multitudes of messages. Satellites have extended the power of communications to report events at the instant of occurrence. Expertise can be shared world wide through teleconferencing, and problems in dispute can be settled without the participants leaving their homes and/or jobs to travel to a distant conference site. Technology has facilitated the sharing of information and the storage and delivery of information, thus making more information available to more people.
In this world of change and complexity, the need for information is of greatest importance. Those people who have accurate, reliable up-to-date information to solve the day-to-day problems, the critical problems of their business, social and family life, will survive and succeed. "Knowledge is power" may well be the truest saying and access to information may be the most critical requirement of all people.
