问题 单项选择题

下列叙述中正确的是______。

A.软件测试应该由程序开发者来完成

B.程序经调试后一般不需要再测试

C.软件维护只包括对程序代码的维护

D.以上三种说法都不对

答案

参考答案:D

解析:程序调试的任务是诊断和改正程序中的错误。它与软件测试不同,软件测试是尽可能多地发现软件 中的错误。先要发现软件的错误,然后借助于一定的调试工具去找出软件错误的具体位置。软件测试贯穿 整个软件生命期,调试主要在开发阶段。为了达到更好的测试效果,应该由独立的第三方来构造测试。因 为从心理学角度讲,程序人员或设计方在测试自己的程序时,要采取客观的态度是程度不同地存在障碍的。 软件的运行和维护是指将已交付的软件投入运行,并在运行使用中不断地维护,根据新提出的需求进行必 要而且可能的扩充和删改。

     I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded

that today's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for

mental illness 50 years ago.

     Why are America's kids so stressed? The report cites two main causes: increasing physical isolation

(隔离) brought on by high divorce rates and less involvement in community, among other things and a

growing perception that the world is a more dangerous place.

     Considering that we_can't_turn_the_clock_back,_adults can still do plenty to help the next generation.

     At the top of the list is nurturing(培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.

     To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for facetoface relationships, and they will get more

sleep.

     Limit the amount of virtual(虚拟的) violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news.

     Keep your expectations for your children reasonable. Many highly successful people never attended

Harvard or Yale.

     Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a

good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.
