答案

参考答案:D

解析: 系统实施是信息系统开发期的最后阶段。系统设计报告提供了实现系统功能的方法、技术和方案,即已给出了实现信息系统的蓝图。 系统设计报告中给出了实施阶段的任务: ①数据库的设计和应用程序的编制。 ②计算机系统的安装、调试和试运行。 ③网络系统的设备安装、联通和调试。 在任务分解中除按在分析和设计中已经明确的划分,即将系统划分为业务系统和技术系统并对两类系统所包含的具体任务进行分解外,还会在实施中遇到必须完成的,而在系统分析和设计中却未明确的任务,它们可能包括:数据的收集和准备、系统的调试和测试、业务人员的培训等,而且它们并不是由程序人员来完成,也应列入任务并排列在进度列中。

When the Young Take Their Lives


A few weeks ago, I received a particularly disturbing page. "A 22-year-old woman is in the emergency room with a gunshot wound to the head," my chief resident told me. (1) . The woman, a recent college graduate, was starting to show signs of brain death. Over the next several hours, we worked to preserve the life she had tried to throw away.
(2) . In the 30 years from 1950 to 1980, the annual suicide rate among college-age women has almost doubled, from 3.9 deaths per 100,000 to 7.0 per 100,000, while the rate among college-age men has tripled, from 10 per 100,000 to 32 per 100,000 a year. (3) .
Students kill themselves at all times of year, but attempted suicides begin to go up in the fall, according to the National Institute of Mental Health. Often the immediate cause seems to be a recent rejection, disappointment or academic failure.
(4) . Even trained mental-health professionals have made mistakes. But there are warning signs you can watch for in friends and loved ones, such as withdrawing from all social activities, dramatic changes in personality—including suddenly becoming much happier or calmer-significant shifts in sleeping or eating habits and giving away cherished personal items.
(5) . Studies of suicide survivors show that often just five minutes elapse from the time someone thinks about committing suicide until the actual attempt.
Finally, it is OK to come right out and ask friends or family members whether they are thinking of suicide. (6) . Be sure to let them know that they are not alone and that help is available through school counselors and mental-health hot lines, in hospitals and now online.
Through the years, I have treated many patients who have attempted suicide. (7) . Our 22-year-old patient is awake now and even talking a bit. I’m optimistic about her physical recovery but disquieted about her chances overall. (8) . What no one knows is whether we will be able to pick up the pieces one more time.
  • A. I do it with the sincere hope that they will get better
  • B. "Oh, and it looks self-inflicted," he added
  • C. The experts will tell you that having tried to kill herself once, she is at a greater risk of trying again
  • D. This year’s toll for adults aged 19 to 24 is expected to reach 1,000 deaths
  • E. Don’t get fooled into thinking that all people who commit suicide have carefully worked out a plan in advance
  • F. You won’t be giving them any ideas
  • G. Trying to determine whether a young person is suicidal can be difficult
  • H. Her predicament made me wonder, once again, what drives people to suicide and why young people resort to such a desperate measure
