While most recent attention in the AI field has been focused on expert system software, AI (66) has also seen dramatic advances. Activity in the past years was characterized by new low-cost, powerful Lisp machines, the introduction of AI workstations, Lisp compilers becoming available for all major professional and engineering workstations, and the personal computer emerging as a (67) . tool for expert system development. The next few years will see this technology evolves further.Because the (68) of an AI computer represents a sizable investment, companies should carefully (69) all options that are available as well as have a good idea of what the next generation of systems will offer in order to (70) the optimum system. This publication provides the information necessary to gain this understanding. (70)是()

A typical (160) language contains an applicative sub-language which approximates the mathematical abstractions of "timeless" functions applied to "spaceless" values, where the actual operation sequences and use of storage space during expression evaluation are organized behind the (161) . In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of spacelessness can be realized by having (162) results during expression evaluation stored at the discretion of the language implementation, and effecting parameter (163) and (164) operations through value copying. (162)是()
A. middle
B. intermediate
C. previous
D. final
Network managers have long (140) practical voice-over-IP (VOIP) solutions. VOIP (141) ease network management and decreases costs by converging a company’s telephony and data infrastructures into one network. And a VOIP solution implemented at a company’s head-quarters with far-reaching branch offices can (142) tremendous amounts of (143) in long distance phone bills, provided that solution delivers POTS-like voice (144) over the Internet. (143)是()

B. money
C. space
D. time
The relational database model requires the data be (110) through programs that don’t rely on the position of the data in the database. This is in direct (111) to the other database mode, where the program has to follow a series of pointers to the data it seeks. A program (112) a relational database simply asks for the data it seeks; the DBMS performs the necessary searches and (113) the information. The (114) on how the search is done are specific to the DBMS and vary from product to product. (111)是()
A. conduct
B. contract
C. contrast
D. construct
