小题1:
Generally, good talkers don’t rush into a conversation. They take their time when they think about something and when they say it out loud. They act as if they have all the time in the world. This makes them the center of attention. Try this way of talking and you will create the same effect.
小题2:
People with good conversation skills tend to notice the kind of things that the average person doesn’t notice, and to bring such details into the conversation. They may notice and point out an interesting ring on the other person’s hand, a certain foreign accent, or a certain voice tone they use when saying a name. Thus, such individuals impress people in a very elegant manner. 
小题3:
It’s very rare to meet a person who is comfortably talking about their emotions and how certain things make them feel, especially with strangers. Yet this way of talking is a real virtue. Don’t just present the facts. Keep in mind that it is at the emotional level that people connect best.
小题4:
Anyone can talk about the news or express basic opinions. But good talkers can frequently tell you something you didn’t know and that you’ll find interesting and fascinating. This is why it’s good to have knowledge into fields such as psychology or sociology, and bring such knowledge out at the right moments in a conversation.
小题5:
The ability to talk smoothly has a lot to do with choosing the precise words to convey your feelings or thoughts. Constantly develop your vocabulary and practice communicating as accurately as possible. It will help you develop a way with words and allow you to express yourself more easily.
