Passage I.
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 homes without fitting locks to their doors.
SATAN can try out a variety of well-known hacking (黑客的) tricks on an Internet site with-out 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 (闖入......行竊).
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 ( 惡意破壞) 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.
21. 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 _____.
A) those happy times appear still to be with us 干擾伎倆: 答非所問+偷換范圍
B) there simply wasn't any crime to worry about 照抄原句 直接排除
C) many sites are not well-protected
D) hackers try out tricks on an Internet site without actually breaking in 偏離定位句子，偷梁換柱。
破解思路：答案推理需結合已通讀部分(第一、二段首句)和文章主線(網絡安全)。
對比喻的理解，找出本體和寓體，然后對照寓體的性質判斷本體的性質。千萬不能直接選擇字面意思！
22. SATAN, a program designed by Dan Farmer can be used ____________.
A) to investigate the security of Internet sites
B) to improve the security of the Internet system
C) to prevent hackers from breaking into websites
D) to download useful programs and information
對原文內容進行兩次定位，答案是對兩處信息的概括 investigative和... try out...
23. Farmer's program has been criticized by the public because .
A) it causes damage to Net browsers
B) it can break into Internet sites
C) it can be used to cause disorder on all sites
D) it can be used by people with evil intent
publicly 勉強算作一個定位提示，criticism 是關鍵。問題設置常見方式：同義替換。
