【单选题】 Artificial rainmaking has been most successful in the ______.
A．lake area
B．western slope of mountains
C．prairie lands
D．windward side of mountains

网考网参考答案：D
网考网解析：
题干artificial rainmaking和原文seeding是同义词，由此判断本题考查的是对第三段倒数第二句话的理解。…the seeding of super-cooled，upslope mountainous winds which have produced additional orographic precipitation on the windward side of mountain ranges．(在山脉的迎风面，通过将颗粒，如碘化银晶体，撒在云里使气流冷却，沿山坡上升，将会产生大量的人工降雨)，因此选 [D] 。人工降雨时，使气流沿山坡上升而冷却产生降雨，并不一定指western slope of mountains，可排除[B] ；[A] 和[C] 与文意不符，故排除。 查看试题解析出处>>
