The
earth
is
our
home.We
must
care
for
it.This
means
keeping
the
land,air
and
water
clean.
Pollution
means
“dirty”.To
pollute
is
to
make
things
dangerous
or
unclean
to
use.Pollution
comes
in
many
different
ways.We
see
it,smell
it,taste
it
and
drink
it.Pollution
is
dangerous
to
our
health,our
happiness
and
our
lives.
Man
has
been
polluting
the
earth
since
the
time
he
first
made
fire,washed
his
clothes
in
the
river
and
threw
his
waste
on
the
ground.When
land
was
used
up
or
water
became
dirty,man
moved
to
another
place.At
first
the
problem
was
not
so
serious
because
there
was
plenty
of
clean
air,land
and
water.There
weren’t
so
many
people
and
their
wants
were
fewer.All
the
dirty
things
could
be
absorbed(吸收)by
nature
quickly.But
this
is
no
longer
true.The
increasing
population
and
the
development
of
industry
have
changed
that.Man
is
slowly
polluting
his
home.
Luckily,people
have
known
the
danger
of
pollution
and
large
numbers
of
people
are
now
working
hard
to
control
pollution.

对于听说训练部分,首先,讨论拯救地球的一些方法,为接下来的听力做铺垫;然后,根据听力内容选择Julia和Jack谈论的内容和他们在过去、现在和将来所要做的事情,实现目标语言的输入,帮助理解环境保护的一些措施;最后,根据听力信息,小组活动,编写对话,口语训练,实现目标语言的输出。
对于阅读语篇材料Rethink,Reuse,Recycle!的学习,利用略读的学习策略,理解2b中Amy
Hayes,Jessica
Wong和Wang
Tao的故事,理解利用废旧物品制作有用的物品,号召人们行动起来,保护环境,为下节课的学习做准备。
思路二:
按照难易,排列顺序,环保措施
→
听力训练,选择措施,实践活动
→
依据信息,小组讨论,环境保护,口语训练,语言输出
→
阅读语篇,掌握大意,了解故事,变废为宝。
准备本节课所需要使用的教学图片,录音机,听力部分的教学磁带。

Last
Monday
our
class
held
an
activity
about
saving
and
protecting
water.
Mr.Wang
was
invited
to
give
us
a
talk.After
his
speech,we
had
a
discussion
on
how
to
save
and
protect
water.
Now
we
know
that
some
of
the
rivers
are
polluted
in
our
country
and
that
we
are
short
of
water
although
there
are
some
rivers
and
lakes
in
our
city.As
a
result,we
need
to
protect
and
save
water.For
example,we
shouldn’t
leave
water
running
after
using
it.Besides,we
mustn’t
throw
rubbish
into
the
river.
After
taking
part
in
the
activity,we
had
a
better
understanding
of
the
importance
of
protecting
the
environment
and
saving
water.

Ⅵ.完形填空(每小题1分,共10分)
The
giant
panda
is
one
of
　36　
in
the
world.A
giant
panda
can
grow
up
to
1.5
meters
long
and
weigh
up
to
160
kg.People
think
the
giant
panda
is
very
lovely.So
it
is
not
surprising
that
the
World
Wide
Fund
for
Nature
　37　
the
giant
panda
as
its
symbol.The
WWF
tells
people
about
animals
that
they
are
in
danger
and
raises
money
　38　
them.
The
giant
panda
only
lives
in
the
wild
in
China.　39　
the
early
1980s,there
　40　
only
1,000
left
in
the
wild.The
main
reason
why
pandas
are
endangered
is
that
the
area
where
pandas
can
live
has
become
smaller.
The
WWF
works
to
help
giant
pandas
in
the
wild
in
many
ways.One
of
the
ways
that
helps
them
is
to
increase
the
size
of
　41　
reserves(自然保护区).Some
reserves
need
to
be
joined
by
　42　
bamboo
between
them
to
make
“hallways”
