空白(2)处应选择()

A.逻辑构件模型

B.物理构件模型

C.组件接口模型

D.系统交互模型

答案

在基于构件的软件开发中,逻辑构件模型用功能包描述系统的抽象设计,用接口描述每个服务集合,以及功能之间如何交互以满足用户需求,它作为系统的设计蓝图以保证系统提供适当的功能。物理构件模型用技术设施产品、硬件分布和拓扑结构,以及用于绑定的网络和通信协议描述系统的物理设计,这种架构用于了解系统的性能、吞吐率等许多非功能性属性。

完形填空

Hello. It’s one of the first words we learn as babies, yet it’s one of the last words we think to use as adults today. That’s unfortunate, because saying hello is more than just saying hello——it is recognition of another’s worth. How might the world change——how might we change——if we mastered this word? To find out, I spent one month saying hello to every person I met. Here’s what I’ve learned.

   It can boost (促进) productivity. In one of the few studies ever done on this subject, Allan All day, an assistant professor of special education at Oklahoma State University, had middle school teachers greet their students individually each morning. This exchange of greetings raised the kids’ productivity. School went from impersonal to personal, and that resulted in more class participation and better grades.

   Environments influence friendliness. One study found that people in the city were less likely to shake hands with a stranger than those in the countryside. My experience was similar. Whatever the reason, my urban hellos were answered far less often than my rural ones. Similarly, people in vacation spots were far friendlier than those hurrying work downtown.

   It’s a form of universal health insurance. It’s impossible to say hello without smiling. And smiling has been shown to lower blood pressure, relieve stress and boost happiness. Apparently, a smile creates a similar effect in the recipient (接受者).

So maybe we can make the world a better place by____________.  After a month of doing it, I feel lighter and I have a better sense of well-being.
