Read the passage and answer the questions:
Our environment really needs protecting. All we have to do something to
save the environment. We should use our cars less. This doesn't mean we
travel less, this means we walk more or we use public transports when we
can, for example, going by bus. That keeps the air cleaner. About in the
home, we save as much as we can. We shouldn't throw rubbish away. We
should use different bags for different things such as, one bag has all the cans
going into it. The second bag has all the papers going into it, and the third
bag has bottles such as oil bottles, wine bottles. Then we can take these bags
to places where they can be recycled. We also save water as well as other
natural resources. Each of us tries a little, the environment will be saved.
