1.“WELL”美国人最为常用的GAP FILLER莫过于WELL。他们在交流时，当听话者想要让说话者知道自己正在准备说话时，就会先用一个WELL揽过话茬。通常这个词的要用升调。例如：

　　A: When are you going to take a trip to Italy?

　　B: Well, I have been preparing for that for a long time and I think it will be in next month。

　　2. “UHMM”这个词也是美国人超级爱用的语气词。发音时就是发出“啊”的音之后再闭上嘴继续“木”音。通常情况下，这个词用来告诉听话者：“我正在思考你所提出的问题”例如：

　　A：Are you gonna be availalbe this Sunday afternoon?

　　B: Uhmmmmm… I am not sure and please let me check my schedule。

　　3. “YOU KNOW”这个我想大家都非常熟知。虽然表面意思是“你知道的”但是更多时候说话者使用了这个词之后马上就要继续阐述自己的观点。例如：

　　A: What would you like to have?

　　B: Well,you know,like always,Orange Chicken!

　　4. “It's like…”美国年轻人超级爱使用这个句式，有时候它被用来打比方但是更多时候是用来打比方同时拖延思考时间。例如：

　　A: How was the show on Sunday?

　　B: Uhmm, it‘s like…it‘s like the one we saw together last year。

　　5. “I mean”这个是我们考新托福口语时的杀手锏，因为有很多的考生在回答问题时，说着说着就跑题了无法自圆其说。为了防止这种现象的出现，我们要迅速反应拉回话题。这时候我们就要用“I MEAN”例如：

　　A: Would you please tell me more about your former university?

　　B: Oh,yes,sure, I went abroad when I was a junior and came back one year later.I transfered to another school right after I came back. Oh, I am sorry, I mean I do not really know that much of it.
