Task 2

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.

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.

Adam's dog, a golden retriever named Hans, can respond to over 150 different commands. Adam cites this fact as evidence for his claim that Hans can understand the English language. Which of the following, if true, casts the most doubt on Adam's claim that Hans can understand the English language?

A．Each of the 150 commands to which Hans responds involves both a spoken word in English and a distinctive hand sign.

B．Hans does not respond to the same commands when spoken to him by Adam's French and Italian friends in their own languages.

C．Scientists have demonstrated conclusively that canine vocal chords are incapable of replicating many of the sounds used in the English language.

D．Animal behaviorists have demonstrated that even very young dogs surpass both wolves and chimpanzees--animals that are thought to be more intelligent than dogs--in the ability to understand human nonverbal communication.

E．The golden retriever is widely considered to be less intelligent than the border collie, and no border collie has ever been shown to truly understand the English language.

听力原文： We've become alarmed over the health center by the number of students who are experiencing hearing loss. First, I want to go over some basic 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 by decibels. One decibel is the lowest sound the average person can hear. Sounds up to 80 decibels generally aren't harmful. That's noise like traffic on a busy street. But anything louder than 80 decibels may hurt your hearing. Once you are up to 140 decibels, that's like a jet plane taking off, then you might even feel pain in your ears. Those 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.

What is this passage talking about?

A．Air pollution.

B．Noise damage.

C．Environment on campus.

D．Solutions for pollution.
