declining years

Carol Spradling, director of the school of computer science at Northwest Missouri State University, said international enrollment began declining precipitously two years ago, following a "perfect storm" that included President Trump's election with his tough talk on immigration and the shooting of an Indian immigrant worker in Olathe, Kan.

美国西北密苏里州立大学计算机学院院长卡萝尔·斯普拉德林说，两年前，特朗普当选总统并就移民问题发表强硬言论，一名印度工程师在堪萨斯州奥拉西被枪杀，国际学生的入学率开始急剧下降。

He spent his declining years ( ie those at the end of his life ) in the country.

他在乡村度过晚年.

In general, prices have been declining since a peak almost two years ago. ( Like a currency exchange, there is a selling price and a buying price.)

大体上来说，自近两年前的高峰之后，金价逐渐走低（就跟货币兑换一样，金价也有买出卖出的价格）。
