根据短文内容,从下框的A—F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余选项。

1.         

     Good communication is vital in modern society. We know that much of the communication is

unspoken. Consciously or unconsciously, we show our true feelings with our eyes, faces, bodies and

attitudes. Your good qualities can make good communication. The personal qualities include physical

appearance, energy, rate of speech, pitch and tone of voice, gestures, expressiveness of eyes, and the

ability to hold the interest of others. What should we do so that our communication will be effective?

Here are my suggestions.

2.        

     Firstly, the trick is to be consistently you, at your best. The most effective people never change

character from one situation to another. They're the same whether they're having a conversation with

their close friends, addressing their garden club or being interviewed for a job. They communicate with

their whole being.

3.        

     Secondly, whether you're talking to one person or one hundred, always remember to look at them.

Don't break eye contact while talking. As you enter a room, move your eyes comfortably, then look

directly at those in the room and smile. This shows clearly that you are at ease. Smiling is important. The

best type of smile and eye contact is gentle and comfortable, not forced.

4.        

      You should also absorb other people before showing yourself. You can't learn anything when you

talk. When you attend a meeting, a party or an interview, don't immediately start throwing your opinions.

Stop for a second. Absorb what's going on. What's the mood of the others - are they down, up, happy,

expectant? Are they eager to learn from you, or do they show resistance? If you can sense what's

happening with others, you will be better able to reach them. So, listen before you talk.

5.        

     How do you get your energy up? Before the meeting, collect your thoughts about the goal of the

meeting - yours and the other's. Once you go through the doorway, no longer think about yourself.

Focus on the person you are meeting to find out what he is interested in. Properly collected energy

comes across when we sincerely believe something. When you speak with energy, you are involved

with your audience and your message. You create an air of certainty. The audience may disagree with

you, but they can't question your belief.
