  • 第6题:

    Software entities are more complex for their size than perhaps any other human construct,because no two parts are alike(at least above the statement level).If they are,we make the two similar parts into one,a(1),open or closed.In this respect software systems differ profoundly from computers,buildings,or automobiles,where repeated elements abound.Digital computers are themselves more complex than most things people build;they have very large numbers of states.This makes conceiving,describing,and testing them hard.Software systems have orders of magnitude more(2)than computers do.Likewise,a scaling-up of a software entity is not merely a repetition of the same elements in larger size;it is necessarily an increase in the number of different elements.In most cases,the elements interact with each other in some(3)fashion,and the complexity of the whole increases much more than linearly.The complexity of software is a(an)(4)property,not an accidental one.Hence descriptions of a software entity that abstract away its complexity often abstract away its essence.Mathematics and the physical sciences made great strides for three centuries by constructing simplified models of complex phenomena,deriving,properties from the models,and verifying those properties experimentally.This worked because the complexities(5)in the models were not the essential properties of the phenomena.It does not work when the complexities are the essence.Many of the classical problems of developing software products derive from this essential complexity and its nonlinear increases with size.Not only technical problems but management problems as well come from the complexity.
    4、____

    A.surface
    B.outside
    C.exterior
    D.essential

    答案:D
    解析:
    软件实体规模上或许比其他任何人类创造的结构要更为复杂,因为没有两个部分是一样的(至少在语句级以上)。如果他们一样,我们便将这两个相似的部分合到一起,成为一个子程序,打开或关闭。在这一点上,软件系统与计算机、建筑或汽车经常混合使用一些重复的元件有很大区别。数字计算机本身比人类所建造的大多数事物都要复杂,他们有超级多的状态。这使得对他们进行想象、描述和测试都很困难。软件系统的状态数目更是比计算机的超出几个数量级。同理,软件实体的扩展不单是这一批元件变大一点,它必将是大量不同元件都有增加。在大多数情况下,构件以非线性的方式相互作用,而整体的复杂性远超线性增加。软件的复杂的特点具有必然性,并非偶然。因此,对于软件实体的描述,剥离了它的复杂性往往就等于剥离了它的本质。过去这三个世纪,通过对复杂的现象构建出简化模型,从模型的属性再倒推,并通过实验验证这些属性,数学和物理科学取得了长足的进步。这之所以行之有效,是因为模型中忽略掉的复杂特性并不是现象中重要的本质属性。而当这些复杂性很重要时,这种方法就会失效。

    PPL scientists will try to solve their problem by ______.
    A

    removing the sugar molecule on the surface of pig cells.

    B

    distinguishing human tissues form those of pigs.

    C

    using the sugar-free nucleus in cloning a pig.

    D

    taking out the sugar genes from the cell of a pig.


    正确答案: C
    解析:
    细节理解题。根据题干信息定位到第三段第三句“PPL scientists recently succeeded in finding the gene responsible for the sugar and knocking it out of the nucleus of a pig cell.”,由此可知,科学家们已经成功的将存在于猪的细胞核里的与糖分子相关的基因剔除了,这些基因存在于猪的细胞核,而不是细胞表面,故A选项错误;B选项的观点无中生有;PPL的科学家想用不含糖的细胞核克隆猪,防止人体产生排斥反应,以解决他们的问题,故C项正确;D选项只是解决该问题过程当中的一个步骤,不是解决问题的全部,故不选。

    the five genetically identical piglets.

    B

    places for the production of tissues.

    C

    animals whose organs would be used for human consumption.

    D

    animals which would be raised in quantity for transplant materials.


    正确答案: C
    解析:
    推理判断题。从题干关键词tissue factories定位到文中第一段最后一句中的“as organ donors for ailing humans”与第二段前两句话可以看出tissue factories指的是专门用来大量培养移植器官的动物体,并作为器官捐献者,故答案为D项。

    请分别描述Pig、Tez和Kafka的功能。

    正确答案: ①Pig是Hadoop生态系统的一个组件,提供了类似SQL的Pig Latin语言(包含Filter、GroupBy、Join、OrderBy等操作,同时也支持用户自定义函数),允许用户通过编写简单的脚本来实现复杂的数据分析,而不需要编写复杂的MapReduce应用程序,Pig会自动把用户编写的脚本转换成MapReduce作业在Hadoop集群上运行,而且具备对生成的MapReduce程序进行自动优化的功能,所以用户在编写Pig程序的时候,不需要关心程序的运行效率,这就大大减少了用户编程时间。
    ②Tez是Apache开源的支持DAG作业的计算框架,直接源于MapReduce框架,核心思想是将Map和Reduce两个操作进一步进行拆分,即Map被拆分成Input、Processor、Sort、Merge和Output,Reduce被拆分成Input、Shuffle、Sort、Merge、Processor和Output等,经过分解后的这些元操作可以进行自由任意组合产生新的操作,经过一些控制程序组装后就可形成一个大的DAG作业。
    通过DAG作业的方式运行MapReduce作业,提供了程序运行的整体处理逻辑,就可以去除工作流当中多余的Map阶段,减少不必要的操作,提升数据处理的性能。Hortonworks把Tez应用到数据仓库Hive的优化中,使得性能提升了约100倍。
    ③Kafka是由LinkedIn公司开发的一种高吞吐量的分布式发布订阅消息系统,用户通过Kafka系统可以发布大量的消息,同时也能实时订阅消费消息。Kafka设计的初衷是构建一个可以处理海量日志、用户行为和网站运营统计等的数据处理框架。

    Good evening, ladies and gentlemen, I’m Roy , and this is my show. This is a television show for all families, and I know you’ll enjoy it.

    Let’s start with a story. Once there was a proud pig on a farm . He thought he was the most important of all the animals on the farm. But it was not enough that he himself thought this: he had to be sure that other animals thought it, too. So he went up to a chicken and asked, “ Who is the most important animal on the farm?” The chicken answered, “ You are, Mr. Pig .” Then he asked a dog, and he got the same reply.

    Next, he asked a cow. When the cow seemed uncertained of the right answer, the pig looked angry, and showed his teeth, “ Oh, you are, of course, Mr. Pig.” said the cow. “ Of course, ” the pig said, “ there is no doubt about it. ”

    At last the pig asked a big horse the same question. The horse lifted one foot, rolled the pig over and placed his foot on the pig’s head. “ I think you know the answer now. ” said the horse.

    Software entities are more complex for
    their size than perhaps any other human construct, because no two parts are
    alike (at least above the statement level). If they are, we make the two
    similar parts into one, a(71 ), open or closed. In this respect software systems differ
    profoundly from computers,buildings, or automobiles, where repeated elements
    abound.

    Digital computers are themselves more
    complex than most things people build; they have very large numbers of states.
    This makes conceiving, describing, and testing them hard. Software systems have
    orders of magnitude more (72 )than computers do.

    Likewise, a scaling-up of a software entity
    is not merely a repetition of the same elements in larger size; it is necessarily an increase in
    the number of different elements. In most cases, the elements interact with
    each other in some( 73 )fashion,and
    the complexity of the whole increases much more than linearly.

    The complexity of software is a(an)(74 )property, not
    an accidental one. Hence descriptions of a software entity that abstract away
