三、那么我们在英语演讲中怎样与听众交流呢，例如：
l.要有值得交流的观点；a message worth communicating;
2.引起听众的注意：抓住他们的兴趣并赢得信任；gain the listeners' attention: capture their interest and build their trust;
3.重视理解；emphasize understanding;
4.获得反馈；obtain their feedback;
5.注意声调，要有感情；watch your emotional tone;
6.说服听众；persuade the audience;

8.眼睛直视听众，或看着他们的鼻梁或下巴 ；look at people straight or look at the bridge of their noses or chins;
9.找到那些看起来比较友善的听众，逐次朝他们微笑；然后目标转向那些有些怀疑的听众，也逐渐朝他们微笑；look for the friendlier faces and smile at them one by one, then move on to the more skeptical members and smile at them one by one also;
