问题 单项选择题

下面是关于Pentium微处理器功耗的叙述,其中错误的是

A.随着微处理器主频和芯片集成度的不断提高,其功耗也会相应增加

B.降低微处理器工作电压是减少芯片功耗的重要途径,目前Pentium 4微处理器的工作电压已经降至2V以下

C.采用新的CMOS制造工艺,并且用铜线代替铝线,可以使功耗进一步降低

D.对微处理器的主频进行分频,使微处理器前端总线(系统总线)频率降低,也能达到降低微处理器功耗的目的

答案

参考答案:D

解析: 该题考查考生对Pentium微处理器的理解。随着微处理器主频和芯片集成度的不断提高,所使用的晶体管更多,其功耗也会相应增加,选项A是正确的:降低微处理器工作电压是减少芯片功耗的重要途径,目前Pentium 4微处理器的工作电压已经降至1.1V到1.6V,所以选项B是正确的:用铜线替代铝线,缩小了线宽,也降低了功耗,所以选项C是正确的;对微处理器的主频进行分频并不能达到降低微处理器功耗的目的:所以应该选择D。

When it comes to human resources, hiring highly-skilled staff is not usually enough for a company to function successfully. Besides the knowledge in their particular fields, employees must always have additional skills-----those of co-operation. In the case that work tasks can only be carried out by communicating with people, accepting common decisions, solving problems, sharing information and helping one another, teamwork skills are important.

While some jobs may require talent, the ability to work as a team is learned. There are no complicated formulas(规则); you don't need to have any special qualities or exceptional mental abilities. Individuals can be effective as a team if they have developed certain behaviors or habits of communication. Many companies, clubs and organizations use team building activities. Team building activities may include a number of teamwork elements. They are aimed at encouraging active participation in task accomplishment while all members have their roles as individuals and are able to co-operate towards a common goal as a team.

Many team building activities focus on problem solving and discussing team issues; thus argument as a way to common consensus (共识) is encouraged. Team building activities often involve recognition and identification of team member skills, talents, knowledge, and experiences which allow the team members to learn more about each other and fully utilize (利用) those skills where appropriate(合适的). Many team activities are focused on developing keys to trust during challenging times.
