Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.
Beginning in the middle of the 20^th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.
By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.
So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.
By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.
So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.

解析

试题分析：这篇短文主要以拟人的手法讲述了环境污染的严重事实，作者通过时间隧道从2500年穿越回到了20到25世纪的不同时代，并描述了各个不同时代的污染的严重性，提醒人类保护环境，爱护人类自己。
小题1:细节理解题。根据短文第二段a few people were worried about polluting the earth’s water and air, but most people did not change their way of life.内容可知，本段主要涉及到了空气质量、水资源和人类的生活方式，唯独没有提到食物方面的问题，故选D。
小题2:词义猜测题。根据本句内容So by the year 2300, there were so many people that food became scarce. 可知，本句中包含一短语so...that...，意为截止到2300年，地球上的人类是如此之多以致于食物变得太少。再加上下一句There was no water to grow food，可知食物应该是不够人类吃的，故选C。
小题3:推理判断题。根据短文第二段but most people did not change their way of life.可知，A选项表述正确；第三段By the year 2200, the earth’s water was completely polluted. People could no longer drink water,可知，B项的描述也是正确的；第四段all of the fish in lakes and seas died because of pollution. 可知C项内容正确；倒数第二段内容说到了2400年，只有富人才有机会离开不适宜人类生存的地球，但是也没有可以适宜人类其他星球供人类居住，可知D项内容不正确；故选D。
小题4:主旨大意题。纵观全文内容可知本文主要描述的就是人类的污染环境极其严重，已经严重威胁人类的生存，到了非停止不可的地步了，所以A项“停止污染”作为文章标题比较合适，故选A 。
