We often hear the_1_ “Bug” while using computers. But what is a bug? In computer science, a bug _2_ an error in software of hardware. In software, a bug is an error in coding or logic that causes a program to malfunction or to _3_in correct results. Minor bugs, for example a cursor that does not behave as _4_can be inconvenient or frustrating, but not damaging to _5_. More severe bugs can cause a program to “hang” (stop responding to _6_and might _7_the user with no _8_but to restart the program. Losing whatever _9_ work had not been saved. In _10_case, the programmer must find and correct the error by the _11_ known as debugging. Because of the _12_risk to important data, commercial application programs are tested and _13_ as completely as possible before release r bugs found after the program becomes _14_are corrected in next update; more _15_bugs can sometimes be fixed with special software, called patches, that circumvents or otherwise _16_its effects. In hardware, a bug is a recurring _17_problem that prevents a system or set of _18_from working together properly.

解析
1.考查名词近义词的辨析。Wording ,diction 指说法，措辞，潜辞造句;Insect 昆虫; term名词术语。
2.考查形似动词词组辨析。recurs to重现; prefers to更喜欢; attributes to归功于，归于;refers to 指的是
3. 考察相近动词辨析 produce 生产，产生; recreate (re前缀表示“再，又”)再创造，再现; achieve 和attain 都表示通过努力取得，得到。
4.考查省略句的用法。完整的句子应该是 as it is expected 意思是“正如人们所预想的”，但通常情况下it is 是可以省略的。
5.这是一个常识性的问题，一般情况下小的一般的病毒不会对计算机的-----有一些影响。Information, memory, news是和计算机有关的常用词，排除了material。有可能对储存信息和上网看新闻有影响，但对整个信息系统是不会有很大影响的。
6.有些病毒可以导致计算机“死机”，即不执行计算机的指令。表示计算机的“指令”，英语中用commands。
7.考查动词的基本用法。四个选项中，grant， retain，reward都是及物动词，直接接宾语，不需要宾语补足语。只有leave后面可以用形容词，介词短语做宾语补足语，表示“使…停留在某种状态”。比如：
He went away, leaving the windows open. 他走了，窗户开着。
He went away, leaving his little brother in tears.小弟弟还在哭，他就离开了。
8. 考查形近词辨析。no后面应该接名词形式，而collective， derivative都只有形容词词性。alternative选择的余地，objective目标，目的。很显然，“死机使计算机操作者别无选择只好重新启动”。
9.考查形近形容词辨析。prestigious有声望的，著名的; precarious不稳定的; previous先前的; precious珍贵的。“重新启动时候，先前所有没有保存的资料就会丢失了。”
10.考查相近形容词的用法。both 和neither，是一对反义词，都修饰可数名词复数形式;either，表示“任何一个”修饰可数名词单数;none，是代词，表示三者或三者以上“都不”，单独使用，要么和of连用。
11.“计算机需要启动杀毒程序”，程序是计算机专用语， process
12. 考查近义词辨析。“由于对于计算机重要数据的潜在威胁” promising有前途的;potential(that may or can come into existence)可能的，潜在的;prospective(hoped for, looked forward to )有望的，可能的：d. probable(likely to happen or prove to be true)可能发生或证实的。由此看出，在平时的学习中，用英语本身来理解词义是很重要的。
