问题 A typical(66)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(67). 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(68)results during expression evalution stored at the discretion of the language implementation, and effecting parameter(69)and(70)operations through value copying.

选项 A、assignment
B、design
C、value
D、dispatch

答案A

解析 (参考译文)典型的强制性语言包含可应用的子语言,该子语言类似于数学抽象中时间厂c限的函数运行于空间无限的值上,而表达式求值过程中实际的操作序列与i存储空间使用都在后台组织。在这种条件下,值一般是数据量小的数据结构,通常是若干字。这也就意味着对“空间无限”的幻觉是表达式求值过程中通过使用中间结果影响参数传递及通过传值安排操作等来实现的。
