  • 第1题：

    设有一组作业，它们的作业提交时刻及估计运行时间如下所示： 作业号 提交时刻 估计运行时间(分钟) Job1 8：30 70 Job2 9：10 30 Job3 9：30 15 Job4 9：50 5 在单道批处理方式下，采用短作业优先调度算法，作业的执行顺序为

    A．Job1，Job4，Job3，Job2

    B．Job1，Job3，Job4，Job2

    C．Job4，Job3，Job2，Job1

    D．Job4，Job1，Job2，Job3


    正确答案：B
    解析：本题考查短作业优先调度算法的概念。短作业(进程)优先调度算法是指对短作业或短进程优先调度的算法。它们可以分别用于作业调度和进程调度。短作业优先调度算法，是从后备队列中选择一个或若干个估计运行时间最短的作业，将它们调入内存运行。而短进程优先调度算法，则是从就绪队列中选出一估计运行时间最短的进程，将处理机分配给它，使它立即执行并一直执行到完成，或发生某事件而被阻塞放弃处理机时，再重新调度。进程首先执行的是Job1，该作业到9:40完成，此时Job2和Job3在等待队列中，按照短作业调度算法，此时执行Job3。Job3在10:10，此时等待队列中有Job2和Job4作业，此时执行Job4，最后执行Job2。正确答案为选项B。

  • 第6题：

    Until the early 20th century failure to bear a son was grounds for divorce.South Koreans greatly preferred boys,who could not only support their parents financially but also carry out ancestral rites.When ultrasound technology became widespread in the 1980s,many South Koreans used it to detect female femses and then have them aborted.Sex ratios became skewed.In response to these trends the South Korean government made it illegal for doctors to reveal the sex of a fetus,Following the Asian financial crisis of 1997,many women took part-time jobs to supplement the family income.Parents noticed,and began to invest more heavily in educating girls.In 2015 three-quarters of South Korean female secondary-schoolers went to university,compared with two-thirds of their male peers.Since 2009 expectant parents have been allowed to know the sex of their baby after 32 weeks'gestation.Many will have found out before,from doctors who trust that parents'attitudes have changed.


    答案：
    解析：
    直到20世纪初，无法生育男孩还是离婚的理由之一。韩国人民非常偏爱男孩，主要是因为男孩不仅可以在经济上赡养父母，还能延续先祖的宗法。20世纪80年代，超声波技术得到广泛应用，许多韩国家庭借此技术手段对胎儿性别进行鉴别，打掉女孩，最终导致男女比例严重失调。时此，韩国政府出台了一项法规，将医生向准父母告知其胎儿性别列为违法行为。继1997年的亚洲金融危机之后，许多妇女通过做兼职工作来补贴家用。父母们意识到了教育的重要性，并加大对女孩子在教育方面的投资。到2015年，有四分之三的中学女生进入大学深造，相比较而言，中学男生大学升学率是三分之二。自2009年起，准父母在怀孕32周后可以知道他们孩子的性别。他们也能提前从医生那里得知，但医生相信准父母的观点已经改变。
