or by bike. We can even walk to work when possible,{#blank#}6{#/blank#}it is really helpful for both of our
budget and health. Thirdly, try best to {#blank#}7{#/blank#}(use)things like books, paper, magazines
and so on. And we can also take a cloth bag when we go {#blank#}8{#/blank#}(shop). Please don't use plastic ones. Of
