英语翻译全文如下People don’t usually take on challenges that are too difficult for them.No one wants to fail or look silly.But sometimes you find yourself in a situation that’s a little harder than you thought it would be.When that happens,you’re in over your head.David Letterman interviews a lot of people on his talk show.And he’s a funny guy,so usually he leads the interview by making jokes.But when he talks to someone very intelligent like Bill Clinton,he finds it hard to match their level of conversation.He’s in over his head.Since Clinton is smart,some of what he says to Letterman goes over his head.That’s a similar but totally different idiom.If something goes over your head,you can’t understand it.
