Picture a wide bowl of tilted land. Rain falls anywhere inside it, runs downhill, gathers into little streams, and all of those streams end in the same river or the same lake. The land is doing the catching, and the edge of the bowl is simply where the ground starts tipping the other way. Once you can see that bowl, you can see the word's other use too: swap the rain for people, and the river for a school, and the same shape is still there.
可以想成一個很大的、傾斜的盆地。雨落在裡面任何一個角落，都會往下流、匯成小溪，最後全進到同一條河或同一座湖。真正在「接」的是那片地，而盆子的邊緣只是地開始往另一邊傾斜的地方。看得到這個盆子，就看得懂它另一個用法：把雨換成人，把河換成一所學校，形狀完全一樣。
