air pollution
waste pollution

a bike instead of driving
bring a bag to go shopping
never take wooden(木头的)
chopsticks or plastic forks
when buying takeaway food
throw rubbish in the bins
Jason and Susan, what are your
ideas for solving these problems?
Yeah, or ride a bike.
There are other
advantages (优点)
of bike riding. It’s
good for health and
it doesn’t cost (花费)
anything!
Well, to cut down
air pollution, we
should take the
bus or subway
instead of driving.
Great ideas! What about waste pollution?
Me, too. Also, I never
take wooden chopsticks
or plastic (塑料) forks
when I buy takeaway
(外卖食物) food. I
use the ones at home.
Mmm, I think
simple things
like bringing a
bag to go
shopping can
help. I started
doing that a
year ago.
And remember to throw
rubbish in the bins and
keep public places clean
and beautiful for everyone.
So together, our actions can make a
difference and lead to a better future!
