25x200+25x4=0
25x200+25x4
25×200+4×25=5100

&&&& T we must take care of it. This means keeping the land, air and water clean. Pollution is a dirty word. To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, taste it and drink it. Pollution is beginning to threaten (威胁) our health,
our happiness and our life. &&&& Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another

chemicals into rivers and lakes we have polluted our drinking water, killing the fish. &&&& Our increasing population is part of the problem. More people, more waste. &&&& Where is this all to end? Are we turning the world into a big rubbish dump (堆存处), or is there any
