问题 单项选择题

面向对象方法的一个主要目标是提高软件的______。

A.可重用性
B.运行效率
C.结构化程度
D,健壮性

答案

参考答案:A

解析: 本题考查面向对象的概念,与传统的软件开发方法不同,面向对象的软件开发方法采用封装、继承、抽象等设计方法,以避免重复设计,至少使重复设计降低到最小程度。在面向对象设计中,可重用性占有非常重要的地位,重用意味着一方面尽量使用目前已有的类,包括开发环境提供的类和开发者已创建的类,另一方面是在创建新类时,在设计中应该考虑它们的可重用性。

To me,life without music would not be exciting.I realize that this is not true for everybody.Many people get along quite well without going to the concert,and listening to the record. But music plays an important part in everyone’s life,whether he realizes it or not.Try to imagine,for example,what films or TV plays would be like without music.Would the feelings,the moving plot,and the greatest interests,be so interesting or dramatic? I’m not sure about it.

Now we have been speaking of music in its more common meaning—the kind of music we hear in the concert hall.We discover them in our everyday life too—in the rhythm of the sea,the melody of a bird in the woods and so on.So music surely has meaning for everyone,in some way or other.  And,of course,it has special meaning for those who have spent all their lives working on playing or writing music.

It is well said,“Through music a child enters a world of beauty,expresses himself from his heart,feels the joy of doing things alone,learns to take care of others,develops his mind and makes his body strong.”
