Hundreds of years ago, life was much harder than it is today. People didn't have modem machines. There was no modem medicine, either.
Life today has! brought new problems. One of the biggest is pollution（污染）. Water Pollution has made our rivets and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It's bad to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt（被状物）over a city. This kind of quilt is called smog（烟雾）.
Many countries are making rules（规则）to fight pollution. Factories mast now clean their water before it is thrown away, and they mustn't let dirty smoke go into the air.
We need to do many other things. We can put waste things in the dustbin（垃圾桶）and do not throw them on the ground. We can go to work by bus with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

【分析】
这是一篇有关环保方面的短文。（1）根据第一段，那是生活艰苦的原因是没有现代化的机器也没有现代化的医药；（2）根据第二段前两名可知，现代生活最大的问题是环境污染，选D，A、B、C所反映的只是一个侧面；（3）根据第二段末句，空气污染才是最严重的污染；（4）是在水排放之前将其净化，water是不可数名词，主语用单数形式it；（5）A说根本没有雾是不客观的，B在污染还未彻底根治之前，尚不能说这一不必彼此大声说话的状况就不存在，怎么可以饮用污染了的水呢？故C也应是排除的，根据文章的意思，D是符合的。
