conversation原型

原型是converse，例如：

1、Building new roads increases traffic and the converse is equally true: reducing the number and size of roads means less traffic.修筑新的道路可增加交通流量，反过来也是同样的道理：减少道路的数量和规模就意味着减少交通流量。

2、They were conversing in German， their only common language.他们正用德语交谈，这是他们唯一的共同语言。

3、Luke sat directly behind the pilot and conversed with him.卢克就坐在飞行员后面，并且和他说着话。
