II. Cloze: 20%(每題1分) 【A】 In Bangladesh, where monsoons once forced schools to shut down for months, an innovative design of "boat schools" has emerged. This project, which is __(16)_ a traditional wooden boat design, ensures that education remains accessible despite devastating floods. _ (17) providing a safe learning environment, the project has been recognized globally for its creative impact. These floating classrooms are now equipped to provide children _ (18)_ modern multimedia resources. The equipment, __(19)_ many high-tech tools such as solar-powered laptops, allows for a more interactive learning experience. The primary goal of these boats is to ensure a stable environment __(20) bridge the educational gap. If this innovative boat school project _ (21)_ today, children in flood-prone regions would not have access to regular schooling. Meanwhile, India is tackling teacher shortages through the induction of Al-powered humanoid robots like Iris. People find__(22) truly fascinating to see how these robots provide a unique chance for personalized learning and go beyond the limitations of a traditional classroom. However, this technological shift is not without debate. _ (23) some critics worry that AI might replace the essential human connection, others argue that these tools can assist every child's learning pace. Supporting this positive view, experts point out that the data-processing speeds of these robots are often much higher than __(24)___ of human assistants. The goal of using such advanced technology is to offer customized learning experiences for every child. This new model allows for flexible study schedules, __(25)_ helps every student succeed. Not only the students but also the teachers can benefit from this silicon-powered model. In the end, these two distinct models-one floating on water and the other powered by silicon-guarantee that no student is left behind. (A) arose from 7. (A) Aside from = ih D 18. (A) as 19.
