问题     In such a changing, complex society, formerly simple solutions to informational needs become complicated. (91) 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 . (92) As families move away from their stable community, their friends of many years, and 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 social changes today is an enormous stockpile of information. (93) 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.  (94) 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 worldwide 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. (95) 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.

选项

答案随着家庭搬离了稳定的社区和多年的朋友,失去了与大家庭的亲戚们的联系,非正式的信息交流便被切断;同时,在需要时就能得到可靠、可信信息的信心也随之丧失了。

解析 该句含有由as引导的时间状语从句。从句中,their stable community, their friends of many years, 和their extended family relationships并列,作介词from的宾语。主句中,the informal flow of information作主语。it代指the informal flow of information is cut off。that information…and reliable作the confidence的同位语。同位语从句中,will be available和 will be trustworthy and reliable是并列谓语。
