【正确答案】smartphone

【答案解析】原文： Hi, everyone. Before I start, I have some important things to tell you. First, there is a change in our project team. Jane Johnson is leaving the team this week. John Smith will replace her to contact our customers. Second, the staff car park will be closed next month for improvement work. The work will last only for a few weeks. Don’t worry. We have found a solution. We can use the local community car park. It’s only a 5-minute walk away from our building. The other thing I want to tell you about is that the canteen has now introduced a cashless payment system. So you can’t use cash for payments anymore next month. You can pay directly with your smartphone. Okay, that’s it. Are there any questions?本题询问他们下个月在餐厅如何付款。讲话者最后提到餐厅引进了一套无现金支付系统，员工将不能再用现金支付，可以直接使用智能手机进行支付。对比题干和听力中的信息，可以确定空格处应该填入smartphone，意为“智能手机”。
