It was late in the afternoon, and I was
putting the final touch on a piece of writing that I was feeling pretty good
about. I wanted to save it, but my cursor had frozen. I tried to shut the
computer down, and it seized up altogether. Unsure of what else to do, I yanked
(用力猛拉) the battery out. Unfortunately, Windows had been in the midst of a delicate and crucial undertaking. The next morning, when I turned my computer back on, it informed me that a file had been corrupted and Windows would not load. Then, it offered to repair itself by using the Windows Setup CD. I opened the special drawer where I keep CDs, but no Windows CD in there. I was forced to call the computer company’s Global Support Centre. My call was answered by a woman in some unnamed, far-off land. I find it annoying to make small talk with someone when A. She had saved what she had written. B. She couldn’t move the cursor. C. The computer refused to work. D. The computer offered to repair itself. [多项选择]分包商接到( )的指令后,完成分包合同约定工作范围以外的施工任务后,承包商应按分包合同的变更对待,给分包商相应的补偿。
