【完成教材3a~3b的教学任务】1.小组内互相交流自己家乡的环境，完成3a表格。2.结合3a记录的内容，以及3b的提示写一篇作文，介绍自己家乡的环境。写完后小组内互相交流纠错，借鉴好词好句，教师抽查点拨。典例参考Dear

problems
are
becoming
more
and
more
serious
all
over
the
world.
With
the
development
of
the
society,
there
are
too
many
cars
on
the
streets.
Cars
have
made
the
air
unhealthy
for
people
to
breathe.
Black
smoke
from
factories
polluted
the
air
seriously.
Factories
also
put
waste
into
the
river.Now
more
and
more
people
have
realized
these
problems.
I
think
that
governments
should
develop
laws
to
stop
people
from
driving
cars
every
day.
I
suggest
everyone
in
this
city
should
help
to
clean
up
the
rivers
and
the
streets.I
hope
the
problem
will
be
solved
and
our
