Passage Two
A "blogger" is a person who writes on an Internet computer website called a "blog". [29]The word "blog" is a short way of saying Web log, or personal website. Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information and ideas to many people who read them. They contain links to other websites. And they provide a place for people to write their ideas and react to the ideas of others. A research company called Perseus has studied more than 3,000 Web logs. [30]It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed his free blog service, weblogs.com. He says the site became too costly to continue. He started the blog four years ago, and thousands of people had written on it. They are now upset because they did not know that the site was closing. [31]One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the website in 1999. She wrote about the history of blogs on the site. That article led to a book called The Weblog Handbook. It has been translated into four languages so far.

Questions 29 to 31 are based on the passage you have just heard.
29. What's a blog?
正確答案：B
解析：細(xì)節(jié)題。錄音第2句就介紹了什么是blog，故答案為B。A是對blogger的定義。
30. Why are blogs most popular with teenage girls?
正確答案：A
解析：本題考查對細(xì)節(jié)的記憶。邊聽邊記與選項有關(guān)的信息對解答本題很關(guān)鍵。錄音中提到blogs最受十幾歲女孩的歡迎，之后馬上說明原因“讓朋友們知道她們生活中的點點滴滴”，即A。B的主語They指代Some people而不是teenage girl。
31. What is true about Rebecca?
正確答案：C
解析：錄音結(jié)尾處專門介紹了Rebecca建立的個人網(wǎng)站——Rebecca's Pocket。能夠與原文所有信息匹配起來的是C。A中動作的主語應(yīng)是Dave Winer；B也存在指代錯誤，可排除；D的主語應(yīng)是The Weblog Handbook而非Her diary。
