问题     Today we are going to practice evaluating the main tool used when addressing groups — the 【B1】______. There are three main elements that combine to create either a positive or negative 【B2】______for listeners. They can【B3】______in a voice that is pleasing to listen to and can be used effectively, or they can create a voice that doesn’t hold the attention, or even worse causes an【B4】______reaction. The three elements are volume, pitch and pace.
    When talking about volume, keep in mind that a good speaker will adjust to the size of both the room and the audience. Of course, with an【B5】______device like a microphone, the speaker can use a【B6】______tone. But speakers should not be【B7】______on it. A good speaker can speak loudly without shouting.
    The second element — pitch — is related to the highness and lowness of the sounds. High pitches are for most people more difficult to listen to, so in general, the speaker should use the lower【B8】______of the voice.【B9】______
    The third element, pace — this is how fast or slow words and sounds are articulated — should also be varied.【B10】______. Pauses ought to be used to signal transitions or create anticipation. It can be very effective when moving from one topic to another【B11】______
【B5】
