写作指导
本次写作内容是一封书信，信中首先要介绍你所在的城市存在有哪些环境问题，是谁造成的这些问题，然后提出解决这些环境为题的方法和措施，可以结合3a中列举
的问题和前面学过的解决办法来完成这封书信。
Dear
Sir/
Madam,
I
have
lived
in
this
city
ever
since
I
was
born
and
I
love
this
city
very
much.
I
think
there
are
beautiful
areas
in
this
city,
but
there
are
also
areas
that
aren’t
attractive.
Like
the
rivers
in
some
villages.
There
is
rubbish
and
waste.
It
is
unpleasant
to
look
it,
smelly,
and
it
makes
the
environment
very
unpleasant.
The
problem
is
there
because
the
factories
put
dirty
waste
into
the
rivers.
People
living
here
may
also
be
throwing
away
too
much
rubbish.
We
could
try
to
ask
people
to
produce
less
rubbish.
I
suggest
that
government
can
close
down
the
factories.
I
believe
that
a
better
environment
can
be
created
in
our
city
and
we
should
all
work
together
to
achieve
it.
Yours
faithfully,
Lin

III.阅读理解
The
world
uses
about
a
thousand
million（百万）tons
of
water
a
day.
Water
is
a
human
right
and
everyone
should
have
their
share.
Yet
more
than
700
million
people
around
the
world
have
trouble
getting
clean,
safe
water.
Treating
wastewater
is
a
good
way
to
provide
fresh
water
for
us.
And
it
also
helps
the
environment
by
keeping
waste
out
of
rivers
and
oceans.
80%
of
wastewater
around
the
world
is
not
treated
at
all,
and
it
is
running
into
oceans.
But
now
we
have
got
the
technology
to
treat
and
reuse
the
wastewater.
While
75%
of
our
planet
is
covered
with
water,
only
2%
is
fresh
water—that
comes
from
rivers,
lakes,
ice
and
snow.
The
rest,
98%
of
the
water,
is
in
seas
and
oceans.
It
is
too
salty
to
drink.
Then
desalination
businesses
come
in.
More
than
19，000
factories
have
been
built
around
the
world,
mostly
in
coastal
countries.
They
process（加工）
more
than
92
million
tons
of
water
every
day.
But
the
technology
they
use
requires
a
lot
of
energy.
Scientists
are
working
to
create
a
less
costly
technology.
They
want
to
produce
20
times
more
clean
water
and
make
sure
everyone
has
enough.
But
for
now,
the
world
still
faces
each
day
with
not
having
enough
water
for
everyone.
( )14.How
many
people
have
trouble
in
getting
clean
water
around
the
world?
A.
Under
10
million.
B.
Only
19
million.
C.
About
92
million.
D.
Over
700
million.
( )15.Treating
wastewater
helps
the
environ?ment
by
________．
A.
storing
waste
in
ice
and
snow
B.
letting
waste
run
into
oceans
C.
keeping
waste
out
of
rivers
and
oceans
D.
sending
waste
to
coastal
countries
( )16.What
does
the
underlined
word
“desalination”
in
Paragraph

mean?
A．远洋运输
B．潮汐发电
C．食盐销售
D．海水淡化
( )17.At
present,
the
technology
to
process
water
________．
A.
needs
much
energy
B.
saves
much
money
C.
satisfies
everyone
D.
causes
pollution
( )18.What
can
we
infer
from
the
last
paragraph?
A.
Water
should
be
a
human
right.
B.
The
water
problem
is
still
serious.
C.
Our
planet
is
covered
with
water.
D.
Everyone
has
enough
clean
water.
IV.根据首字母提示完成下面包含本单元词汇的短文
Our
environment
is
polluted.
One
kind
of
pollution
is
from
transportation
and
19.i________
that
burn
much
coal.
Another
is
from
people.
For
example,
fishermen
kill
sharks
for
fins.
This
is
not
only
cruel
but
also
20.h________
to
the
environment.
We
know
sharks
are
at
the
top
of
the
food
chain
in
the
ocean's
ecosystem.
Besides,
no
21.s________
studies
show
shark
fins
are
good
for
health.
What
an
upside
down
thing
they
do!
People
also
throw
litter
everywhere.
They
even
throw
22.p________，
waste
iron,
metal
or
bottles
into
bins.
So
I
think
we
can't
23.a________
to
wait
any
longer.
A
24.p________
said
we
should
take
action
in
developing
laws
to
protect
our
environment
and
we
should
take
part
in
the
environmental
study
from
the
25.b________
of
our
hearts.
We
should
turn
off
lights
when
we
leave
rooms.
We'd
better
use
reusable
bags
instead
of
paying
for
plastic
bags.
We
should
put
old
things
to
good
use.
We
can
26.r________
books
and
paper.
We'd
better
bring
waste
back
to
life
with
our
creativity.
For
example,
we
can
reuse
the
wooden
gates
that
were
pulled
down.
We
can
turn
ugly
things
into
beautiful
works.
There
are
many
27.a________
of
doing
these.
We
can
get
inspiration
from
them
and
it
doesn't
28.c________
anything.
