【答案解析】[听力原文] Education experts have urged teachers in Kenya and elsewhere in Africa to embrace digital technologies to improve teaching and learning. The call was made by speakers during a two-day international conference. The meeting, called 'Education Innovation Africa,' was held on June 8 and 9, 2015 in Nairobi. Conference organizers said their goal was to showcase inspirational ideas for improving teaching and learning using technology. Isaac Kinyanjui of eLimu Kenya, an education technology start-up company, spoke to the delegates about what he called smart classrooms of the future in Africa. He said such classrooms will require teachers and learners to be innovative beyond the use of traditional textbooks. 'Publishers won't allow the reproduction of entire textbooks because they still need to sell their books. So we need to be innovative about digital content development,' Mr. Kinyanjui said. He added that the content has to be 'rich and culturally relevant.' He said students should be able to use it on multiple platforms, such as PCs, laptops, computer tablets and mobile phones.
