主旨歸納題

　　(1)以偏概全：在概括文章或段落大意時，用某一個段落的觀點或細節冒充全文主要觀點、中心思想的選項。也就是歸納概括的范圍不足。

　　(2)主題擴大：歸納概括的范圍過大，超過了文章討論東西，與主旨大意是包含關系。

　　3.態度語氣題：

　　干擾選項通常說法片面或偏激。六級閱讀所選文章通常是理性的說明和論證，具有較強邏輯性，作者對于所討論專題的態度不會是極其偏激的。如目前只作為干擾項出現過的有arbitrary(武斷的)，subjective(主觀的)，prejudiced(有偏見的), indifferent等。而成為正確選項的最安全選項是concerned。這類題目抓住基本特征，是屬于必得的分數。

　　四、基本技能再回顧及應用 (以上各種干擾項的特征需牢記在心)

　　要求：

　　1。一定要控制自己不看原文直接選擇答案的沖動!

　　2。寫出每一個題目里面的錯誤類型，。

　　下面的各篇文章題目對我們以上講過的干擾選項的所有情形包含在內了。要小心應付。

　　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.
