6、lly at a loss why. Qian Liang: Well, there might many causes for system crash. One of them is siftware. The simplest operation like installing and uninstalling might cause a crash in system. Problems within the system may also do that, so you have to be very careful when deleteing DLL files, modifyi

7、ng Windows registry, or upgrading the operating system. Another cause is the hardware problem.Have you tried backing up the files? It would be a great help in system restoration when the problem doesnt lie in the hardware.,2020/10/8,10,陳紅：我剛好在用 Photoshop畫圖，屏幕就黑了。一切發(fā)生得很突然，我 簡直都不知所措，這是為什么。 錢亮：哦，系統(tǒng)崩潰可以

8、有許多原因。其中之一是軟件。像安裝或卸載軟件這樣最簡單的操作都會造成系統(tǒng)崩潰。系統(tǒng)內(nèi)部的問題也會如此，所以說，當你刪除DLL文件、修改Windows注冊、或者系統(tǒng)升級的時候要特別小心。另一個原因是硬件問題。你備份過文件沒有？當問題不在于硬件的時候，在恢復系統(tǒng)時，備份文件會幫大忙。,系統(tǒng)崩潰,參考譯文,2020/10/8,11,Cheng Hong: The service personnel installed a ghost problem for me when I brought the computer. Will I lose the data in my hard disk if

9、it is restored? Qian Liang: Not except the data on C:drive, where files on your desktop or in My Documents are stored.

11、一個可啟動的磁盤或者是在DOS系統(tǒng)下(如果有的話)把這些文件移到其它位置。 陳紅： “我的文檔”中和桌面上有很多學習資料。你能幫我把它們轉(zhuǎn)存一下嗎？這樣可以省去我找客戶服務的麻煩，而最重要的是，我能從你那兒多學一點。 錢亮：沒問題。,系統(tǒng)崩潰,參考譯文,2020/10/8,13,Words and Expressions 1.coordinatev. 協(xié)調(diào)，使一致 kordnet 2.allocatorn. 分配者lukeit 3.batch processing 批處理bt prusesi 4.bundlev. 捆bnd()l 5.real-timea. 實時的riltaim 6.simul

20、ux 操作系統(tǒng)是否需要反病毒保護的爭論或許永遠沒有結(jié)束的時候。 Linux的設計方法使得在 Windows 環(huán)境下工作的病毒很難在 Linux下工作。 但是對人們來說，要找到一種攻擊 Linux 的方法并非沒有可能。 另一種想法是：電子郵件中的病毒或許不會影響 Linux 電腦，但是，攜帶病毒的郵件一旦找到一條途徑，即你的朋友使用 Windows 并連接到你的電腦上，那么病毒就會對他實施嚴重破壞。 不管病毒對你的系統(tǒng)有害與否，避免病毒出現(xiàn)在你的 PC機上或許是該做的正確事情。慶幸的是有一些 Linux 反病毒程序- AVG 和 ClamAV。,2020/10/8,21,Words and Ex
