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.

為什麼P在平面x=5上可假設P(a,b,5)不是（5,a,b)

範例11 16+2 空間中「求距離」的應用16 -45==π 在坐標空間中有三點(1,3,2)、B(3,1,2)、C(0,2,4)都在平面E上,設 AB 的垂 直平分面為E,BC的垂直平分面為E,已知E、E與平面x=5交於P點,P點在平 面E上的投影點為Q。試問: √14 (1)P點到平面E的距離為2/3 (2)QA 的長為 2 由提示- (1) AB = (2,-2,0),AC=(-1,-1,2) n 平面E的法向量 平行AB×AC=(-4,-4,-4) 故設 n = (1,1,1),平面E:x+y+z=k,將A(1,3,2)代入 得k=6,所以E:x+y+z=6 PA=PB=PC,P點在平面x=5上 ,所以可假設 P(a,b,5)點在平面配 上的投影點 Q 為△ABC的什麼心? 因為P點在平面E上,且E是AB的垂直平分面,所以PA=PB,同理,P點在平面E上 且E是BC的垂直平分面,所以PB=PC,因為P點在平面x=5上,所以可假設P(a,b,5)69 | PA² = PB² ⇒ (a-1)²+(b-3)+(5-2)=(a-3)+(b-1)+(5-2) PB² = PC2 ⇒ (a-3)+(b-1)+(5-2)=(a-0²+(b-2)+(5-4 ⇒ a=b ⇒ 3a-b=7 解 a = b = 7 7 =子,故P(a,b,5)=(3.3.5),P點到平面E的距離為 177 3+2+5 +5-6 =2√3 2 2 √√12+12+12 (2)E與E的交線垂直平面E,所以P點在平面上的投影點 Q 為△ABC 的外心 △PQA 為直角三角形,PA= ,QA=√PA²-PO² = 14 √62 2 = 2 鬼冷
