【答案解析】[听力原文] May I have your attention please? I would like to remind you all of the safety measures that we have put in place here in our factory. For your own safety, all employees are required to wear the safety glasses which are provided near the door and the newly introduced safety clothing. I do not need to mention that this is strictly a non-smoking floor, and all visitors to the floor are also advised to wear the masks and head coverings which have also been provided as further safety measures. As I guide you through each station around the floor, I ask that you reserve any questions you may have for after the tour.
[解析] 该题询问说话人的行为，由此可以判断考生是否掌握了全文大意。本文后半部分提到As I guide you through each station around the floor.由此可知说话人负责介绍工厂见习。
