解析：
36. 根据前文语境，城里的访客来到这个村子，arrived（到达）符合语境。
37. 前文提到有人喜欢吃蛙腿，后文说他们自身青蛙不足，是转折关系，However（然而）表转折，符合逻辑。
38. 他们自身青蛙不够，所以想要从其他地方购买青蛙，buy（买）符合文意。
39. 地里有大量青蛙，且村民起初认为它们没用，这对村民来说是不劳而获的收入，“money for nothing”是固定表达，意为“不劳而获的钱”。
40. 结合后文“They were not useless”可知，起初村民认为青蛙没用，were not useful符合语境。
41. 村民要做的就是捕捉青蛙来换钱，catch（捕捉）符合题意。
42. 有了卖青蛙的收入，村民第一次能憧憬更好的未来，better（更好的）符合语境。
43. 根据后文转折内容可知，变化一开始几乎没被察觉，at first（起初）符合逻辑。
44. 根据后文买药品的内容可知，孩子更经常生病，fall ill（生病）是固定搭配。
45. 此处指用卖青蛙赚来的钱，made作后置定语修饰money，表示“赚来的钱”。
46. 后来村民察觉到了问题的根源，realized（意识到）符合文意。
47. 根据后文介绍青蛙的作用可知，问题出在青蛙身上，frogs符合语境。
48. “with so many frogs killed”是with的复合结构，表伴随，意为“随着这么多青蛙被杀死”，符合逻辑。
49. 昆虫吃庄稼和传播疾病是并列关系，and（并且）表并列。
50. 结合村子原本贫穷的背景可知，现在村民仍然很穷，still（仍然）符合语境。
