【正确答案】 1、moment    

【答案解析】原文：Today, I’d like to talk about packaging. Just take a moment to memorize the last item you bought. Was it something to eat, to drink, to apply or to wear? Now that you have the item in your mind, could you tell what impression its packaging brings to you? What image comes first to your mind? Do you think about its safety, design or looks? Packaging is there to fulfill its mission. Either it is pulled off in order to start using the product it holds inside, or it is thrown away as soon as the packaging content runs out. The main purpose is to protect its contents from any damage.讲话者开门见山提出演讲的主题，即外包装。随后让大家回忆最近购买的是什么东西，提出了如何看待产品的包装等一系列问题。空格前为冠词a，推测空格处应填入名词(词组)，结合录音填入moment，意为“片刻”。
