&& Part 1 Notes to Text High-level Programming Languages 1) Instructions written in a high-level language must be translated into the machine language used by the com puter system.用高级语所编写的指令,必须被翻译成 计算机系统中所采用的机器语言。 注释:在此句中 written in a high- evel language是过去分词短 语做定语,修饰主语 nstructions;过去分词短语 used by the computer system也是定语,修饰 ithe machine language 2) This means that program written in a high-level language such as COBOL should run on any computer system with COBOL compiler..那就意味着以某种高级语 言,例如 COBOL编写的程序,应在带有 COBOL编译程序的 计算机系统中运行。 注释:此句的主语This指代上文;tha引导的是宾语从句;过去 分词短语 written in a high- evel language.修饰that program;介词短语 with COBOL compiler修饰any com puter systen。 2021/2/20 P2
2021/2/20 P.2 @ Part 1 Notes to Text 1) Instructions written in a high-level language must be translated into the machine language used by the computer system. 用高级语所编写的指令，必须被翻译成 计算机系统中所采用的机器语言。 注释：在此句中written in a high-level language是过去分词短 语做定语，修饰主语Instructions；过去分词短语used by the computer system也是定语,修饰the machine language。 2) This means that program written in a high-level language such as COBOL should run on any computer system with COBOL compiler．那就意味着以某种高级语 言，例如COBOL编写的程序，应在带有COBOL编译程序的 计算机系统中运行。 注释：此句的主语This指代上文；that引导的是宾语从句；过去 分词短语written in a high-level language修饰that program；介词短语with COBOL compiler修饰any computer system。 High-level Programming Languages
3)In actual practice, however, several variations have crept into high-level languages so that no high-level language is totally portable" to all com puter systems with a compiler for the language in question.在实际运用中,一些变化已潜入到高级语言 中,以至于没有一种高级语言能完全移植到带有这种语言编译程序的 计算机系统中。 注释: so that引导的是结果状语从句;介词短语 in question是定语, 修饰 the language,意思是“本文所讨论的语言”。 4)The reader of a program is much more likely to detect wrong functionality if the program has been written in a high-level language rather than in a lower-level one 如果此程序是用高级语言编写而不是低级语言编写的话,阅读程序者 发觉函数错误的可能性就要大得多。 注释:此句是系表结构;ikey是形容词,作表语;不定式 to detect wrong functionality用作状语,修饰表语ikey;连词词组 rather than意思是“而不是”。 2021/2/20 P3 End
