Question

【題目】E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(偽裝)itself as an “important message”from a friend. In spite of a weekend of warnings，more than 50 000 computers at about 100 places around the world have been attacked by the virus，computer security experts said on Monday.

The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被傳染的)e-mails. Although the virus causes no serious damage to a computer，its effect was far reaching.

To make matters worse，a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.

The Melissa virus comes in the form of an e-mail，usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says，“Here is that document you asked for...,don’t show it to anyone else.” Attached(附)to the message is a document file.

Once the user opens that file，the virus digs into the user’s address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(電子數(shù)據(jù)文件)file. When the user opens that file，the virus sends 60 infected e-mails.

The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don’t know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.

【答案】

【1】B

【2】C

【3】A

【4】B

【解析】這是一篇說明文。主要說了成百上千的公司以及政府辦公室都遭受到病毒“梅麗莎”和“怕怕”的攻擊，介紹了病毒“梅麗莎”與“怕怕”出現(xiàn)的時(shí)間、攻擊方式、影響、影響深遠(yuǎn)的原因等。

【1】細(xì)節(jié)理解題。根據(jù)“E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(偽裝)itself as an “important message”from a friend.”可知病毒“梅麗莎”是通過偽裝成一個(gè)十分重要的信息來攻擊郵件系統(tǒng)的。故選B。

【2】細(xì)節(jié)理解題。根據(jù)“Papa is programmed to send out even more infected e-mails than Melissa.”“怕怕”被編寫得能夠散播更多的感染郵件，甚至超過“梅麗莎”，可知，“梅麗莎”能夠散播大量的受感染的信息。故選C。

【3】細(xì)節(jié)理解題。根據(jù)“Although the virus causes no serious damage to a computer，its effect was far reaching.”盡管病毒對(duì)電腦并沒有什么嚴(yán)重的損壞，但它的影響是深遠(yuǎn)的�？芍�“梅麗莎”不會(huì)對(duì)電腦造成巨大損壞，故選A。

【4】細(xì)節(jié)理解題。根據(jù)“Once the user opens that file，the virus digs into the user’s address book and sends infected documents to the first 50 addresses.”一旦用戶打開文件，病毒就會(huì)挖掘用戶的聯(lián)系人名單并給前50個(gè)人發(fā)送感染文件。可知，“梅麗莎”是通過用戶的聯(lián)系名單傳播的，故選B。
