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. Farmer 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 ail 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.
单选题
By saying "…owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors" (Lines 5—6, Para. 1), the author means that______.
【正确答案】
C
【答案解析】细节判断题。本题问通过“owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors”这句话，作者想表达什么意思。作者一开头说的是英国乡村的人们十分怀念当初不用锁门的日子，通过“Amazingly, these happy times appear still to be with us in the worlds biggest community”，我们明白，作者实际上是想作一个类比，再结合下文的内容，他实际上最想表达的意思是突出说明现在许多网址的安全并未引起注意，因此[C]为正确答案。
单选题
SATAN, a program designed, by Dan Farmer, can he used______.
【正确答案】
A
【答案解析】细节判断题。本题问沙坦程序可用来做什么。根据文章第二段第一句“SATAN can try out a variety of well-known hacking (黑客的) tricks on an Internet site without actually breaking in.”和第三段第二句“SATAN has done more to alert people to the risks…”可知，A项“用来涮查网址的安全问题”最切题，为正确答案。本题的干扰项是[B]、[C]，但仔细分析就不难发现，[B]“提高网络系统的安全”其实比文中的“alert”一词的意思不同，而[C]“防止黑客进入”正好与文中“人们担心有人利用它来进行破坏”的意思相反。
单选题
Farmer's program has been criticized by the public because______.
【正确答案】
D
【答案解析】细节判断题。本题问“法莫设计的程序被公众批评的原因”。根据第二段第三句“A person with evil intent could use it to hunt down sites that are easy to burgle.”可知，[D]“它可以被有恶意的人利用”符合题义，应为正确答案。[A]意为“它对网络浏览器造成破坏”；[B]意为“它可以闯入网址”与文中“SATAN can try out a variety of well-known hacking tricks on an Internet site without actually breaking in.”一句矛盾；[C]意为“它可以引起所有网址的混乱”，与第一段最后一句中的“well over half of all World Wide Web sites”不符。
