1.Scientists say the thinning ozone layer over the South Pole makes climate change take place more quickly than in other areas of the world.
语法分析：make是使役动词。最常见的使役动词有：make, have, leave。 他们都表示“使得……”，后面都可接宾语+宾语补足语的结构或从句。
2.ANTOINCE GUICHARD: "It is so expensive that if you don't help each other, usually you just don't manage. And now with Antarctic science being really a global science and part of understanding how the world works, it is becoming really vital that everybody works together."
语法分析：so that是结果状语从句
it is becoming really vital that everybody works together.it是形式主语，真正的主语是everybody works together。使用形式主语可以避免句子看上去头重脚轻。
