Volume is the highness or lowness of the speaker’s voice. Pitch is how loudly or softly you speak.

听力原文： Today we are going to practice evaluating a main tool used when addressing groups—the voice. There are three main elements that combine to create either a positive or negative experience for listeners. They can result in a voice that is pleasing to listen to and can be used effectively. Or they can create a voice that doesn't hold attention. Or even worse, causes an adverse reaction. The three elements are volume, pitch and pace.

When evaluating volume, keep in mind that a good speaker will adjust to the size of both the room and the audience. Of course, with an amplifying device like a microphone, the speaker can use a natural tone. But speaker should not be dependent on microphones. A good speaker can speak loudly without shouting.

The second element, pitch is related to the highness or lowness of the sounds. High pitches are for most people more difficult to listen to. So, in general, speaker should use the lower registers of their voice. During a presentation, it's important to vary pitch to some extent in order to maintain interest.

The third element, pace, that is how fast or slow words and sounds are articulated should also be varied. A slower pace can be used to emphasize important points. Note that the time spent not speaking can be meaningful too. Pauses ought to be used to signal transitions or create anticipation. Because a pause gives the listener time to think about what was just said or even to. predict what might come next, it can be very affective when moving from one topic to another.

What I'd like you to do now is watch and listen to a videotape and use the forms I gave you to rate the speaking voices you hear. Then tonight, I want you to go home and read a passage into a tape recorder and evaluate your own voice.

According to the professor, what can a speaker do to keep an audience's attention?

A．Speak very loudly.

B．Ask questions frequently.

C．Vary tone, volume, and speed of speech.

D．Limit the speech to fifteen minutes.

Task 2

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

In China phone talk is expensive. If you want to make it cheaper, make phone calls using the Internet, which can cost as little as 30% or even 5% of a traditional call.

But changing your DDD (domestic direct dial) and your IDD (international direct dial) calls for the net version, called voice over the internet protocol (互联网协议) or VoIP, requires you to choose between different types of technology, with different advantages.

If a telephone connection was a road, a regular phone call allows you and the person you are calling to share the road without anyone else. On this empty road, the connection is fast, efficient, and uninterrupted. But with VoIP technology, your voice is broken into millions of separated packets of information that share the road with all the billions of other bits of information on the Internet. When the packets reach the person you are calling, they are gathered to resemble your voice. Depending on which type of VoIP you are using, the speed of the Internet connection, Internet traffic, and the service provider, the resulting voice quality can vary -- from quite good to quite awful.

The three main ways of using the internet to make calls are PC-to-PC (家用电脑) calls, PC-to-Phone calls and China's popular IP phone card.

VoIP calls are cheapest when they are made between two computers or between a PC and a telephone. For both, make sure you have a computer, an internet connection, a sound card, and most importantly, a headset (套头耳机) with a microphone.

People prefer IP phone calls to ordinary ones because the former is ______.

A．much more convenient

B．much cheaper

C．more dependable

D．more efficient
