【正确答案】improvement

【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?本题询问为什么下个月关闭员工停车场。讲话者提到，员工停车场下个月因修缮将被关闭。对比题干和听力中的信息，可以确定空格处填入improvement，意为“改善”。
