【正确答案】 1、proud    

【答案解析】原文：Thank you all for coming and joining us here today. Before we get started, I’d like to express my gratitude to all of you who help us make this event run smoothly. Today marks our 8th annual group meeting. We are proud to be able to host it here at Guangzhou with all of you. During the next two days, you’ll know more about our initiatives through our different activities. I hope that they will prove to be special and fulfilling for you. They are of course not the only things important to you. You will also be meeting lots of new people and making new friends along the way.讲话者在上一句提到今天是第8次年度集团会议，本句应该表述讲话者在这么有意义的日子能够和大家一起举办会议的心情。空格前是系动词are，空格内应填入表达心情的词。结合录音填入proud，意为“自豪的”。
