In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn’t any crime to worry about.
Amazingly, these happy times appear still to be with us in the world’s biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors.
SATAN can try out a variety of well-known hacking tricks on an Internet site without actually breaking in. Fanner has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle.
But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder. So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer.
At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage.
But let’s look on the bright side. Given the lack of locks, the Internet is surely the world’s biggest (almost) crime-free society. Maybe that is because hackers are fundamentally honest. Or that there currently isn’t much to steal. Or because vandalism isn’t much fun unless you have a peculiar dislike for someone.
Whatever the reason, let’s enjoy it while we can. But expect it all to change, and security to become the number one issue, when the most influential inhabitants of the Net are selling services they want to be paid for.
46. By saying “... owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors” (Lines 3-4, Para. 2), the author means that ______.
47. SATAN, a program designed by Dan Farmer can be used ______.

第1题:
细节事实题。题干意思是“通过提到‘…owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors’(第2段第3-4行),作者的意思是……”。根据第二段第二句中的using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors.(用他自称为“撒旦”的自动调查程序所做的一项最新研究表明,超过一半以上的万维网网站主人建立的家都没有上锁)可知,许多网站没有得到很好的保护;A项“那些快乐的时光似乎还在我们身边”,B项“根本没有什么犯罪需要担心”,D项“黑客们在网站上尝试各种技巧,但实际上并没有入侵网站”都不是作者在这里想表达的。因此C项“许多网站没有得到很好的保护”正确。
第2题:
判断推理题。题干意思是“撒旦,一个由Dan Farmer设计的程序可以被用来……”。根据第二段第二句using an automated investigative program of his own called SATAN(用他自称为‘撒旦’的自动调查程序)和第三段的第一句SATAN can try out a variety of well-known hacking tricks on an Internet site without actually breaking in.(“撒旦”可以对网站试验一系列众所周知的黑客攻击而不用真正闯入)可以推断出“撒旦”这个程序是用来检验网站是否安全,B项“完善互联网系统的安全性”,C项“阻止黑客闯入网站”,D项“下载有用的程序和信息”都不是“撒旦”的功能,因此A项“检验网站是否安全”正确。
第3题:
细节事实题。题干意思是“Farmer的项目受到了公众的批评,因为……”。根据第三段第三句A person with evil intent could use it to hunt down sites that are easy to burgle.(一个有邪恶意图的人可以用它来搜索容易被盗窃的网站)可知D项“它可以被恶意的人利用”符合题意。A项“它会对网络浏览器造成损害”,和B项“它可以侵入互联网站点”不是“撒旦”造成的后果,也不是这个项目受到公众批评的真正原因;根据第四段第二行SATAN has done more to alert people to the risks than cause new disorder.(“撒旦”做的更多的是提醒人们注意风险,而不是引起新的混乱)可知,C项“它可以用来在所有的网站上造成混乱”错误。因此D选项正确。
第4题:
作者态度题。题干意思是“作者对‘撒旦’的态度是……”。倒数第二段第一句提到But let’s look on the bright side. Given the lack of locks, the Internet is surely the world’s biggest (almost) crime-free society.(但我们也要看到光明的一面,不考虑安全因素,因特网几乎是世界上最大的没有犯罪的社会)和最后一段第一句说道Whatever the reason, let’s enjoy it while we can.(不管是什么原因,让我们在还能享受的时候尽情享受吧),由此可推断作者对“撒旦”的态度是积极的,因此C项“积极的”正确。A项“热心的”,B项“批评的”和D项“漠不关心的”都不符合。因此选C正确。
第5题:
判断推理题。题干意思是“文章最后一段……”。倒数第二段第一句提到But let’s look on the bright side. Given the lack of locks, the Internet is surely the world’s biggest (almost) crime-free society.(但我们也要看到光明的一面,不考虑安全因素,因特网几乎是世界上最大的没有犯罪的社会)和最后一段第一句说道Whatever the reason, let’s enjoy it while we can.(不管是什么原因,让我们在还能享受的时候尽情享受吧),由此可推断作者对“撒旦”的态度是积极的,因此C项“积极的”正确。A 项“热心的”,B项“批评的”和D项“漠不关心的”都不符合。因此选C正确。
