32、y way of hosting and attending a meeting.”可以推断 it指的是网络会议。 因此空格处必定会提到这一词眼。备选项有 A和 G,G 项极具概括性。应该放在第一段的位置。故 排除。 2.F 根据上文的“at their own desks”可知参会者在自己的办公桌就可以参会,F项顺理成章。 3.C 根据后文的“saves the use of paper but also greatly reduces the mailing cost”可知,既节约了用纸又 省下来邮寄的费用,也就是说参会者看到的是电子的,因此选 C 项。 4.B 由第五段可知,网络会议节省了参会者的食宿费,唯一用到的能源就是电脑使用的电,因此使用 的能源较少。 5.D 根据后文的“they can more easily find their working partners who have the same green ideas.In return,they develop good relationship with other companies and improve their business”可知,they代指的 是公司,与 D项中的 Companies 呼应。
