A. characterized by sugar and sweetness

(以糖和甜味为特征)

A选项错误。

B. becoming smaller due to natural disaster

你是不是不认识inhospitable：不适宜居住的

(逐渐变成不适宜居住的地方)

C选项正确。

D. marked by manmade extreme weather

哈哈，你选错了吧!

你把题干和这个选项连在在一起读呢!

人类理想的居住地是以人为极端天气为特征。

我们又不自虐。理想居住地肯定不是以人为极端天气为特征。

只能说现在的人类理想居住地将来可能会被人为极端天气变的不宜居!

One billion people will live in insufferable heat within 50 years

五十年内十亿人将生活在不堪承受的酷热之中

背景：根据近期发表的一份研究，气候灾难对人类的伤害将来势越来越凶猛，范围越来越广，而且来的速度也会比之前预计的要快;全球平均气温每上升一摄氏度，就将有近10亿人不得不背井离乡或忍受难熬的酷热。这项研究还预测，在最糟糕的可能性模拟中，在五十年内，全球人口就将有三分之一生活在和撒哈拉大沙漠一样热的地方;即使在最幸运的条件下，也会有12亿人居住的地区不再是人类繁盛了近6000年的舒适气候区。
