III. Fill in each of the blanks with one of the words given in the following list, making

changes if necessary:

A compiler, in computer science, is a computer program that translates source code into

object code. Software engineers write source code using high-level programming languages

that people can understand. Computers cannot directly execute source code, but need a

compiler to translate these instructions into a low-level language called machine code.

Compilers collect and reorganize (compile) all the instructions in a given set of source

code to produce object code. Object code is often the same as or similar to a computer’s

machine code. If the object code is the same as the machine language, the computer can run

the program immediately after the compiler produces its translation. If the object code is not

in machine language, other programs —such as assemblers, binders ( 联编程序), linkers, and

loaders ( 加载程序) —finish the translation.

Most computer languages use different versions of compilers for different types of

computers or operating systems, so one language may have different compilers for personal

computers (PC) and Apple Macintosh computers. Many different manufacturers often produce

versions of the same programming language, so compilers for a language may vary between

manufacturers.

IV. Translate the following passage from English into Chinese:

在软件中，错 误是指导致程序发生故障或产生不正确结果的编码或逻辑错误。较轻

微的错误，如光标表现异常，会造成不便或带来挫折，但不会对信息产生破坏性 影响。

较严重的错误会导致程序“中止”(对命令停止反应)，可能使用户别无选择，只能重新

启动程序，结果致使任何前面已经做 好但尚未保存的工作丢失。两种情况无论是哪一种，

程序员都必须凭借称为调试的过程，发现并改正错误。由于错误对重要数据的潜在危险，

商 用应用程序在发行前要经过尽可能全面的测试与调试。程序发行后发现的较轻微错误

在下一次更新时改正;较严重的错误有时可用称为补丁的特殊软 件加以修补，以规避问

题或减轻其影响。
