问题 单项选择题

下列一组描述中,正确的是( )。

A.系统软件就是买来的软件,应用软件就是自己编写的软件
B.CPU可直接执行机器语言程序,高级语言程序须经过编译才能执行
C.一台计算机配了某语言,说明一开机就能用该语言编写和执行程序
D.计算机程序就是计算机软件,计算机软件就是计算机程序

答案

参考答案:B

解析:系统软件是指控制和协调计算机及外部设备,支持应用的软件开发和运行的系统,是无需用户干预的各种程序的集合,主要包括操作系统、语言处理程序、高级语言系统和各种服务性程序等,因此A选项的说法错误。一台计算机配了某语言,说明用户可以在该台计算机上使用该语言编写源程序或执行使用该语言编写的源程序,因此C选项错误。计算机程序不等同于计算机软件,计算机软件由程序及其相关文档组成,而计算机程序并不包括文档。

At times we all get angry when we are driving. It might be because we are stuck in a traffic jam or stuck behind a very slow driver. It might be because we think another driver has done something very stupid and dangerous. Whatever the reason, it seems that getting angry in a car is something which happens more and more often and there is now a special term for it “road rage”. Some experts even think that road rage is a kind of mental illness! How can we recognize this “illness” of road rage?

There are two kinds of road rage: aggressive driving and aggressive reactions to the way other people are driving. Aggressive driving can take different forms:

●Driving much faster than the speed limit.

●Increasing your speed very quickly.

●Driving very close behind the car in front and sounding the horn or flashing the headlights.

●Changing lanes very suddenly and blocking another car.

●Moving into a parking space where another car is trying to park.

There are also different reactions to the way other people are driving. These include:

●Making rude signs at people.

●Shouting at people and threatening them.

●Deliberately driving into another person’s car.

●Hitting somebody.

●Using a weapon such as a baseball bat, or even a gun or a knife.

Road rage is certainly not a joke. There have been incidents of road rage which have led to serious injuries and even murder.

Experts think that one reason for road rage is that films show a lot of examples of fast and aggressive driving such as car chases where this kind of driving seems to be positive.

Experts also think that the punishments for dangerous driving are not serious enough.

Experience shows that driving problems can be controlled, but it takes a long time. In the UK in the last 30 years, the police have been quite successful in reducing the number of people who drink and drive. They are now working to stop people using mobile phones when they are driving. Let’s hope they can have the same success with the road rage.
