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： We've become really alarmed over the health center by the number of students we are seeing, who are experiencing hearing loss. First, I want to go over some basics about hearing. Then we can take a look at our school environment and see if we can figure out some ways to protect hearing. The leading cause of preventable hearing loss is excessive noise. Too much moderate noise for a long time or some types of intense noise for even a short time can damage hearing. Loudness is measured in units called decibels. One decibel is the lowest sound that the average person can hear. Sounds up to 8O decibels generally aren't harmful. That's noise like traffic on a busy street. But any- thing louder than 80 decibels may eventually hurt your hearing. Once sounds are up to around 140 decibels, that's like a jet plane taking off, then you might feel pain in your ears. And pains are sure sign that your hearing's at risk. Even one exposure to a really loud noise at close range can cause hearing loss. So what you need to do is limit your exposure to harmful levels. If you pass along this handout, we can take a look at the decibel level of some common campus sounds. Notice how loud those horns are that people take to football games. They are really dangerous if blown right behind you. Now, let's try to generate a list of damaging noises.

Which of the following titles is most appropriate for the passage？
Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Security experts were not surprised by the FBI's warning last week that more than 1 million credit card numbers have been stolen from e-commerce websites in the last 12 months by crackers who took advantage of a hole that could have been patched with software that was made available three years ago. It is believed that most of the dirty work was being done by organized hacking groups in Russia and the Ukraine.
Many of their peers in the Western world say Eastern Europe's computer crackers and hackers are the most skillful in the world--far superior to the so-called "script. kiddies" who have gained a fair amount of notoriety(臭名昭著). "We call Russia the Hackzone because there are so many of us here, and we are so good at what we do," said a self-described cracker living in Moscow. He claims he is often hired to "have fun" with the websites and networks of his employer's competitors. He is paid 3,000 rubles(卢布) per job--about $ 104 American. It may not sound like much, but a college professor gets paid about $ 150 per month.
The Russian hacking scene is incredibly sophisticated. These guys are excellent programmers and they really understand networks--how to get in and out without a trace, which makes it unusual that they have been at the center of some notorious computer crime cases.
To the Moscow residents, who describe them as "secret security guy", cracking and hacking are important parts of the underground culture in Russia, as they are in many other countries. But they feel that there is more approval for Russia's crackers throughout Russia than there is elsewhere. When they were in school, in the 1980s, they were encouraged to hack American software. They had to dissect(仔细研究) the programs to understand them so that they could make them work on their systems. It is believed that many Russian teenagers start cracking because they want to get on the Internet but can't afford the costs of the service. So they learn how to steal passwords. Furthermore, they can't afford to spend two months' salary on a copy of Microsoft Office. But they can spend a half-month salary and get a CD burner that lets them make many copies of software. What is the better investment？
