SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文: Moving away from newspapers, let's now focus on magazines. Now the first magazine was a little periodical called the Review and it was started in London in 1704. It looked a lot like the newspapers of the time, but in terms of its contents it was much different. Newspapers were concerned mainly with news events but the Review focused on important domestic issues of the day, as well as the policies of the government. Now, in England at the time, people could still be thrown in jail for publishing articles that were critical of the king. And that is what happened to Daniel Defoe. He was the outspoken founder of the review. Defoe actually wrote the first issue of the Review from prison. You see, he had been arrested because of his writings that criticized the policies of the Church of England, which was headed by the king. After his release, Defoe continued to produce the Review and the magazine started to appear on a more frequent schedule, about three times a week. It didn't take long for other magazines to start popping up. In 1709, a magazine called the Tattler began publication. This new magazine contained a mixture of news, poetry, political analysis and philosophical essays.
What is significant about the review?

A. Its publication was banned by the British government.
B. It was the first weekly newspaper.
C. It caused a prison revolt.
D. It was the first magazine ever published.

W: Really?
M: Yeah, So what you are doing this summer, anything special?
W: Well, actually yeah. My parents have always liked taking my sister and me to different places in the United States. You know, places with historical significance. I guess they wanted to reinforce the stuff we learned in school about history. And so even though we are older now, they still do once in a while.
M: Oh so-where you're going this summer?
W: Well, this summer it's finely going to be Gettysburg.
M: Finely? You haven't been there yet? I mean Gettysburg, it's probably the most famous civil war site in the country. It's only a couple of hours away. You think that would be one of the first places that they've taken you to. I have been there a couple of times.
W: We were gonna to go about ten, ah, no, it was exactly ten years ago, but I don't know, something happened, I cannot remember what.
M: Something changed your plans?
W: Yeah, don't ask me what it was, but we ended up not going anywhere that year. I hope that doesn't happen again this year. I wrote a paper about Gettysburg last semester for a history class I was taking. Well, about the political situation in the United States right after the battle at Gettysburg. So I'm eager to see the place.
What are the students mainly discussing?
