66. A fire b_______ out last night.

Hundreds of years ago, life was much harder than today. People couldn’t use modern machines. Of course, there was no modern machine, 　　41　 .

Life today is better, but there are new problems. One of the biggest problems is pollution. Water pollution has 　　42　 　our rivers and lakes dirty. It kills our fish and affects our drinking water. Noise pollution makes us 　　43　 　louder and become angry more easily. Air pollution is the most serious kind of pollution. It affects 　　44　 　living thing in the world.

Cars, planes and factories all pollute our air every day. Sometimes the pollution is so 　　45　 　that it is like a quilt (被子) covers a city. This kind of quilt is called smog (雾).

Many countries are making new laws to 　　47　 　pollution. Factories must now clean waste water 　　47　 　it is thrown away, and they mustn’t blow dirty smoke into the air.

We need to do many other things. We can put waste things in the dustbin 　　78　 　throwing them on the ground. We can go to work by bus 　　49　 　go to our office with our friends in a car.

If the traffic is less and 　　50　 , the pollution will be less. And the environment will be better and better.
