1．Hundreds of years ago，life was harder than it is today．People didn't have modern machines．There was no modern medicine，either．
Life today has brought new problems．One of the biggest is pollution．Water pollution has made our rivers 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 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．
Many countries are making rules to fight pollution．Factories must 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 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．

20．For several years，Americans have enjoyed tele-shopping---watching TV and buying things by phone．Now tele-shopping is starting in Europe．In a number of European countries，people can turn on their TVs and shop for clothes，food，toys and many other things．
Tele shopping is becoming popular in Sweden，for example．The biggest Swedish company sells different kind of things on TV in 15European countries，and in one year it made 100million．In France there are two about 20million a year to buy things through those channels．
In Germany，until last year tele-shopping was only possible on one channel for 1hour every day．Then the government allowed more tele-shopping．Other channels can open for tele-business，including the largest American tele-shopping company and a 24-hour tele-shopping company．German businesses are hoping this new tele-shopping will help them sell more things．
Some people like tele-shopping because it allows them to do their shopping without leaving their homes．With all the problems of traffic in the cities，this is an important reason．But at the same time，other Europeans do not like this new way of shopping．They call tele-shopping"Junk （垃圾） on the air"．Many Europeans usually worry about the quality （质量） of the things for sale on TV．Good quality is important to them，and they believe they cannot be sure about the quality of the things on TV．
The need for high quality means that European tele-shopping companies will have to be different from the American companies．They will have to be more careful about the quality of the things they sell．They will also have to work harder to sell things that the buyers cannot touch or see in person．
