【文章大意】由于人们错误的生活方式，他们没有意识到环境污染的严重性，从而导致现在地球上的污染日益严重。如果人们再不改变生活方式，在未来地球也许将不会适合人类居住。
1. D 【解析】细节理解题。根据短文第二段中的wrried abut the plluted water and air以及mst peple did nt change their way f life可知，这一段中提到了污染的水和空气，也提到了人们的生活方式，没有提到食物，故选D。

Peple culd n lnger drink the water, and they had t use ther types f liquids可知B不对；C选项文中没有提到；根据Yu see scientists did nt find anther safe planet可知D不对。
5. B 【解析】主旨大意题。这篇短文讲述了现在地球上的污染非常严重，这主要是由于人们的生活方式不正确导致的，如果人们再不改变，到2400年，地球将不再适合人类居住，人类只有离开地球。故B选项的Change r Leave，改变还是离开，最具有概括性，并能提炼出文章的主题，是适合做题目的。
