问题 单项选择题

如果杀毒软件报告一系列的Word文档被病毒感染,则可以推断病毒类型是(1),如果用磁盘检测工具(CHKDSK、SCANDISK等)检测磁盘发现大量文件链接地址错误,表明磁盘可能被(2)病毒感染。 空白(2)处应选择 ()

A.文件型

B.引导型

C.目录型

D.宏病毒

答案

参考答案:C

解析:

本题考查计算机病毒方面的基础知识。

计算机病毒的分类方法有许多种,按照最通用的区分方式,即根据其感染的途径以及采用的技术区分,计算机病毒可分为文件型计算机病毒、引导型计算机病毒、宏病毒和目录型计算机病毒。文件型计算机病毒感染可执行文件(包括EXE和COM文件)。

引导型计算机病毒影响软盘或硬盘的引导扇区。宏病毒感染的对象是使用某些程序创建的文本文档、数据库、电子表格等文件。目录型计算机病毒能够修改硬盘上存储的所有文件的地址,如果用户使用某些工具(如SCANDISK或CHKDSK)检测受感染的磁盘,会发现大量的文件链接地址的错误,这些错误都是由此类计算机病毒造成的。所以,上面两空的答案分别是D和C。

love charity(慈善) shops and so do lots of other people in Britain because you find quite a few of them on every high street. The charity shop is a British institution, selling everything from clothes to electric goods, all at very good prices. You can get things you won’t find in the shops anymore. The thing I like best about them is that your money is going to a good cause and not into the pockets of profit-driven companies, and you are not damaging the planet, but finding a new home for unwanted goods.

The first charity shop was opened in 1947 by Oxfam. The famous charity’s appeal to aid postwar Greece had been so successful it had been flooded with donations(捐赠物). They decided to set up a shop to sell some of these donations to raise money for that appeal. Now there are over 7,000 charity shops in the UK. My favourite charity shop in my hometown is the Red Cross shop, where I always find children’s books, all 10 or 20 pence each.

Most of the people working in the charity shops are volunteers, although there is often a manager who gets paid. Over 90% of the goods in the charity shops are donated by the public. Every morning you see bags of unwanted items outside the front of shops, although they don’t encourage this, rather ask people to bring things in when the shop is open.

The shops have very low running costs: all profits go to charity work. Charity shops raise more than £110 million a year, funding(资助)medical research, overseas aid, supporting sick and poor children, homeless and disabled people, and much more. What better place to spend your money? You get something special for a very good price and a good moral sense. You provide funds to a good cause and tread lightly on the environment. (08天津卷)
