I'm sure you
all know how important recycling is. Recycling is when you collect old things
and turn them into new things. It sounds like magic. B{#blank#}1{#/blank#} in fact it's very scientific.
How it all
works? The first thing is to collect items that can be recycled. Soda cans are made
out of metal. Some bottles of juice are made out of g{#blank#}2{#/blank#}. Magazines and newspapers are made
out of paper. Bags are made out of plastic. Many o{#blank#}3{#/blank#} old things can be recycled, too.
Let's get
back to the process（过程）of recycling. Once you put all
your items in a recycling factory. There, the materials get separated. They go
into d{#blank#}4{#/blank#} piles. There are special machines that crush（挤压变形）each pile together. The materials c{#blank#}5{#/blank#} into square cubes（立方体）.
They are really heavy. It is h{#blank#}6{#/blank#} for humans to carry them. Companies buy these
cubes and turn them into n{#blank#}7{#/blank#} products.
Now let's
take a closer look at how old paper is transformed（改变形态）. First the paper is torn（撕）into tiny p{#blank#}8{#/blank#}. Then a special water with chemicals
is poured onto them. The fibers start to stick together. In time, a completely
new roll of paper is c{#blank#}9{#/blank#}! If
there were things written or printed on the first paper, they disappear.
Recycling
keeps our planet healthy. It reduces waste and saves money. It a{#blank#}10{#/blank#} saves energy. You can do your part. So just
remember the golden rule always recycle your products!
