问题 单项选择题

显示控制卡也称显卡、显示卡、图形卡、图形加速卡或视频适配卡。下面有关PC机显示卡的叙述中,错误的是

A.目前PC机使用的显卡大多数与VGA标准兼容

B.图像的展现和图形的绘制主要由显卡中的显示控制器完成

C.目前有些计算机的显卡是集成在主板上的

D.目前多数显卡采用PCI总线接口

答案

参考答案:D

解析: 该题考查考生对显卡的理解。目前PC机使用的显卡大多数与VGA(视频图形阵列适配器)兼容,VGA格式分辨率是640×480,帧频是60Hz,每个像素可选取256种颜色,所以选项A是正确的;显示卡的基本作用就是控制PC机的图形输出,包括两方面的控制功能:一方面负责对CRT或液晶显示器的工作进行控制,另一方面与CPU一起完成图像的显示和图形的绘制操作,所以选项B是正确的;通常是以 附加卡的形式安装在PC机主板的扩展槽中,或集成在主板上,所以选项C是正确的;显示控制器目前大多通过AGP端口直接与系统内存连接,选项D是错误的,所以应该选择D。

单项选择题
完形填空

What is the secret ingredient of tough people that enables them to succeed? Why do they survive the tough times when others are overcome by them? Why do they win when others lose? Why do they soar when others sink?

The answer is very simple. It's all in how they sense their problems. Yes, every living person has problems. A problem-free life is an illusion —a mirage(海市蜃楼) in the desert. Then accept that fact.

Every mountain has a peak. Every valley has its low point. Life has its ups and downs, its peaks and its valleys. No one is up all the time, nor are they down all the time. Problems do end. They are all resolved in time.

You may not be able to control the times, but  you can compose your response. You can turn your pain into profanity —or into poetry. The choice is up to you. You may not have chosen your tough time, but you can choose how you will react to it.

The positive solution to a problem may require courage to do it. When you control your reaction to the seemingly uncontrollable problem of life, then in fact you do control the problem’s effect on you. Your reaction to the problem is the last word! That’s the bottom line. What will you let this problem do to you? It can make you tender or tough. It can make you better or bitter. It all depends on you.

In the final analysis, the tough people who survive the tough times do so because they've chosen to react positively to their dilemma. Tough times never last, but tough people do. Tough people stick it out. History teaches us that every problem has a lifespan.
