The sense of sound is one of our most important means of knowing what is going on around us. Sound has a waste product, too, in the form. of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.

Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.

There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems.

Noise adds more tension to a society that already faces enough stress.

But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots(战车) from moving through the streets at night!

Ways of making less noise are now being tested. There are even laws controlling noise. We cannot return to the "good old days" of peace and quiet. But we can reduce noise—if we shout loudly enough about it.

Why are scientists surprised by the findings in their noise study？

A．Because the world is becoming increasingly noisy.

B．Because they have learned that noise is also is also a kind of pollution.

C．Because noise is an unwanted waste for human beings.

D．Because people knew little about noise before.

The largest shark known to us, Megalodon, is extinct. Or is it？ Carcharodon Megalodon, commonly known as Megalodon, is believed to have lived between I million and 5 million years ago and thought to have been 52 feet long. It is (or was) a shark that had a jaw 7 or more feet wide. Fairly recently, there has been some speculation about whether it is extinct or just out of reach. But few people believe that Megalodon has found a home deep in the ocean.
There are many known "Living Fossils": Coelacanth, Sea Cucumbers, Sea Urchins, Lobsters, Sea Stars. The common ones like lobsters and sea urchins are not really looked on as anything amazing. They've been around for thousands of years or more, and axe easily accessible to us. What if they weren't accessible and yet still existed？ We would label them extinct. The discovery of a live Coelacanth, a fish long believed extinct, challenged some scientists' long-held beliefs on extinction. There have been recent discoveries Of incredibly large squid, and deep-sea fish never before seen by scientists.
In the 1960s the U.S. Navy set up underwater microphones around the world to track Soviet submarines. The network, known as the Sound Surveillance System, still lies deep below the ocean's surface in a layer of water known as the "deep sound channel'. The temperature and pressure of the channel allow sound waves to travel undisturbed. NOAA's Acoustic Monitoring Project has been using the Sound Surveillance System to listen for changes in ocean structure like ocean currents or volcanic activity. Most of the sounds recorded are common and of no concern. One sound, identified in 1977 by U.S. Navy "spy" sensors, was odd. It was obviously a marine animal but the call was more powerful than any of the calls made by any other reported sea creature. It was too big for a whale. Could it be a deep-sea monster？ One possibility was a giant squid, but no one is sure. It was named "Bloop". Could it be Megalodon？ If Megalodon is still alive down in the bottom of the ocean, we may some day soon discover it. Then what？ Deep sea diving will never be the same, that's for sure!
The following is commonly known EXCEPT ________.
A．Megalodon, the largest shark, is extinct
B．Megalodon is not extinct but just out of reach
C．Megalodon was 52 feet long and had a jaw 7 or more feet wide
D．Megalodnn lived between several million years ago

听力原文：W: Hi, Frank. What are you up to？ Is that really a French grammar book？
M: Well, I'm trying to teach myself some French. When I go to Montreal next semester, I don't want to sound like just another tourist. Most of the people there are bilingual.
W: Leave Boston to go to Montreal？ I didn't know this university had a program in Canada.
M: It doesn't. I'm planning to take a short leave of absence from school, so I can go there on my own.
W: What's the reason for this sudden interest in Canada？ M: Well, actually I've been thinking about going for some time now. I know someone there who's been wanting me to visit.
W: A relative？
M: An old friend of my uncle's runs a chemical engineering department there. So, I'm hoping he can help me enroll in some interesting courses.
W: If you want those credits transferred back here later on, you'd better arrange for it before you leave. Don't forget what happened to Susan after she came back from Rome.
M: Yeah, but her situation was different. I already have all the credits I need to graduate.
W: So you'll be taking courses just for the sake of learning.
M: That will be a nice change of pace, won't it？

A．Planning a sightseeing tour.
B．Writing to his uncle.
