The topic of this programme is
environmental protection. We human beings {#blank#}1{#/blank#}(do) a lot of things at the cost of the
environment to develop economy quickly in the past few years. I do think it is time
for us to understand the {#blank#}2{#/blank#}(important)
of protecting the environment and do something about it. And today I would like
{#blank#}3{#/blank#}(introduce)
some simple but useful ways that we can follow {#blank#}4{#/blank#}(easy) in our daily life. Firstly, turn {#blank#}5{#/blank#}lights if it is unnecessary. Then, go out
in environment﹣friendly ways such as by bus, by subway
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
course the public should raise environmental awareness and realize it is {#blank#}9{#/blank#}(everyone) duty to protect the
environment. Last but not least, the government should make laws to guide
people's {#blank#}10{#/blank#}(behave).
