问题 单项选择题

()专门用于翻译汇编语言源程序。

A.编译程序

B.汇编程序

C.解释程序

D.链接程序

答案

参考答案:B

解析:

本题考查程序语言翻译基础知识。

用某种高级语言或汇编语言编写的程序称为源程序,源程序不能直接在计算机上执行。如果源程序是用汇编语言编写的,则需要一个称为汇编程序的翻译程序将其翻译成目标程序后才能执行。如果源程序是用某种高级语言编写的,则需要对应的解释程序或编译程序对其进行翻译,然后在机器上运行。

解释程序翻译源程序时不产生独立的目标程序,而编译程序则需将源程序翻译成独立的目标程序。

链接程序则用于将多个目标程序链接起来,以形成可执行程序。

     It was one of the hottest days of the dry season. We had not seen     1  _ for almost a month. The
crops were dying. If it didn't rain soon, we would lose everything.
     At noon, when I was     2      making lunch, I saw my five-year-old son, Billy,      3     towards the.
woods. Minutes later, he ran back and then     4     walked towards the woods. This action-walking
carefully to the woods and running back to the house, went on for nearly an hour.
     Finally I couldn't take it any longer and decided to follow him. As I entered the woods, I saw the
most    5     sight. Two large deer appeared in front of him, and a little deer     6  _ on the ground, clearly
suffering from heat exhaustion (中暑) , was lifting its head to lap (舔) up the water cupped in my son's
hands. When the water was gone, Billy ran back to the house. I     7     him back to a water tap.  Billy
turned it on and knelt (跪) there, letting the drops slowly fill up the "cup" formed by his hands,      8      he
stood up, I was there in front of him.  His eyes just filled with tears. "I'm not wasting _  9  _, Mum," he
said. "No, Billy. I am _10    of you!"

deer.
