【正确答案】 1、different activities    

【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.根据空格前的形容词性物主代词our，可推测空格处应填入名词(词组)。根据句中的through “通过”可推测该空格处所填内容应和某种方式有关系。结合录音填入different activities，意为“各种活动”。
