試題6
People are i ndulging in an illusion whenever t hey find themselves explaining at a cocktail(雞尾酒) party, say, that they are "i n computers," or "in telecommunications," or "in electronic funds transfer". The implication is that they are part of the high-tech world. Just between us, they usually aren't. The researchers who made fundamental breakthroughs in those areas are in a high-tech busi ness. The rest of us are （1） of their work. We use computers and other new t echnology components to develop our products or to organize our affairs. Because we go about this work in teams and projects and other tightly knit working groups(緊密聯(lián)系在一起的工作小組), we are mostl y in the human communication business. Our successes stem
from good human int eractions by all participants in the effort, and our failures stem from poor human interactions.
The main reason we tend to focus on t he （2） rather t han the human side of the work is
not because it's more （3） , but because it's easier to do. Getting the new disk drive installed is positively trivial compared t o figuring out why Horace is in a blue funk(恐懼) or why Susan is dissatisfied with the company after only a few months. Human interactions are complicated and never very crisp(干脆的,干凈利落的) and clean in their effects, but they matter more than any other aspect of the work.
If you find yourself concentrating on the （4） rather than the （5）, you're like t he
vaudeville character(雜耍人物) who loses his keys on a dark street and looks for them on t he adjacent street because, as he explains, "The light is better there!".
（1）A、creators
B、innovators
C、appliers
D、inventors
（2）A、technical
B、classical
C、social
D、societal
（3）A、trivial
B、crucial
C、minor
D、insignificant
（4）A、technology
B、sociology
C、physiology
D、astronomy
（5）A、technology
B、sociology
C、physiology
D、astronomy查看答案
試題參考答案：C、A、B、A、B
試題7
以下關于單身模式(Singleton)的描述中，正確的是（ ）。
A、它描述了只有一個方法的類的集合
B、它能夠保證一個類只產(chǎn)生一個唯一的實例
C、它描述了只有一個屬性的類的集合
D、它能夠保證一個類的方法只能被一個唯一的類調用查看答案
試題參考答案：B
試題8
在CPU中用于跟蹤指令地址的寄存器是( )。
A．地址寄存器(MAR)
B．數(shù)據(jù)寄存器(MDR)
C．程序計數(shù)器(PC)
D．指令寄存器(IR)查看答案
試題參考答案：C
試題9
若視頻圖像序列中兩幀相鄰圖像之間存在著極大的相關性，則這種相關性稱為（ ）冗余。
A、空間
B、時間
C、視覺
D、信息熵查看答案
試題參考答案：B
試題10
So it is today．Schedule disaster functional misfits,and system bugs all arise because the left hand doesn't know what the right hand is doing．As work （1）, the several teams slowly change the functions,size, and speeds of their own programs, and they explicitly or implicitly （2）their assumptions aboutme inputs available and the uses to be made of the outputs.
For example, the implementer of a program-overlaying function may run into problems and reduce speed relying on statistics that show how （3）this function will arise in application programs．Mean-while back at the ranch, his neighbor may be designing a major part of the supervisor so that it criticallydepends upon the speed of this function．This change in speed itself becomes a major specificationchange, and it needs to be proclaimed abroad and weighed from a system point of view.
How, then, shall teams （4）with one another? In as many ways as possible.
?Informally．Good telephone service and clear definition of intergroup dependencies will encourage the hundreds of calls upon which common interpretation of written documents depends.
?Meetings．Regular project meetings, with one team after another giving technical briefings, are （5）．Hundreds of minor misunderstandings get smoked out this way.
?Workbook．A formal project workbook must be started at the beginning.
（1）A．starts
B．proceeds
C．stops
D．speeds
（2）A．change
B．proceed
C．smooth
D．hide
（3）A．frequently
B．usually
C．commonly
D．rarely
（4）A．work
B．program
C．communicate
D．talk
（5）A．worthless
B．valueless
C．useless
D．invaluable查看答案
