2　妙笔成篇
Dear
editor,
　　In
recent
years,
severe
haze
weather
has
frequently
occurred
in
China,
which
has
done
great
harm
to
people’s
health.
Many
traffic
accidents
happened
in
haze
weather
and
some
people
even
got
injured
or
lost
their
lives.
　　Now
that
we
have
realized
the
great
harm
caused
by
the
haze,
we
should
take
measures
to
reduce
it.
It
is
necessary
for
the
government
to
raise
people’s
awareness
of
protecting
the
environment.
In
addition,
people
should
go
to
work
by
bus
or
by
bike
if
possible
instead
of
driving
as
well
as
plant
more
trees
to
clean
the
polluted
air.
Only
in
this
way
can
we
save
ourselves
from
the
haze.
Yours
sincerely,
Li
Hua
Thank
you
