多看看美剧，生活类型的。
准备一本词典。
说同一个意思时，尽可能多的使用同义词或短语。比如说问好的时候，你可以直说'Morning/Evening'，或者说'What's up'，或是“Sup, man”。同时配上丰富的表情，还有友好的动作。
当别人想你问候的时候，用不同方式回答。别使用教科书式的回答。反例：Q: How is it going?A: Fine, thank you. And you?（×）更好的回答：Q: How is it going?A: Pretty good! I've been to... and it was so fun!（√）A: Oh, man. You suck! Don't you just know that I failed the exam today?（√）A: It was fine. I'm working on... it's kind of hard to me, but I can handle this.（√）
要有逆向思维和批判性思维。当别人问你一些简单问题的时候，就要多说一些,故弄玄虚或者拐弯抹角。例：Q: How is it taste?A: Uhm... it is crispy, tastes like cookie but too much sweet.Q: What time is it right now?A: Dude, you're not still asking this ancient question at our dating, are you?
从言行举止上提升。别再坐的端端正正的像个小学生，坐姿随意一点，只要不夸张做作就好。动作简练，少有多余的动作等等（这些还得根据具体情况自己把握）。
反应快一点。动作和对话都要快一点，别让别人觉得你很迟钝。
多学习多记忆
