像美國人一樣說英語:Nicole practices her election speech

Susan: what's up, Nicole?
Nicole: I pulled an all-nighter working on my election speech.
Susan: no wonder you look like a basket case! Did you finish your speech?
Nicole: yes, at 6 a.m.
Susan: that must be a load off your mind!
Nicole: it's not. I've got to give the speech tomorrow in front of 1,500 people. I'm a nervous wreck!
Susan: just remember the old rule of thumb: imagine your audience naked.
Nicole: that's gross. Why would I want to do that?
Susan: according to conventional wisdom, it'll make you less nervous.
Nicole: only practice will do the trick.
Susan: okay, let's hear the speech.
Nicole: good afternoon, everyone. There are four candidates running for president. You think you have several choices. In reality, you have just one choice: me!
Susan: you can't say that. You'll turn off your audience immediately.
Nicole: it sounds like I have a big head?
Susan: I'll say!
