　　A:这些机器有什么问题？

　　B:They're quite complex machines and they have a lot of different components. We need to check the metal casing regularly for any signs of corrosion. We also check the brushes once a fortnight to make sure they aren't worn down. It's important to make sure everything is properly aligned and we adjust it if necessary. There is a canvas belt at the end of the assembly line. If it gets wet, it might rot so we check that regularly too.

　　B:这些机器相当复杂，它们有很多不同的配件。我们需要检查一下金属外壳看看有没有腐蚀的痕迹。我们也要两星期一次对刷子进行检查，确定没有磨损。确保每个件进行合适的校正是非常重要的，如果有必要我们要对其调整。在装配线的尾部有个帆布带。如果帆布袋湿了，它会腐烂，因此我们对它也要进行定期检查。
