六、阅读填空
根据短文内容，从方框中选出五个句子放入文中空缺处，使短句内容通顺完整。
Why
Live
Near
the
River?
Imagine
pioneers
travelling
west
in
the
1800s．In
those
days,
it
was
hard
to
find
running
water
and
shops
where
to
buy
things．As
time
went
by,
most
pioneers
had
to
make
their
homes
near
a
river
so
that
they
could
get
water
easily.
How
did
rivers
help
people
live
in
the
past?
Back
in
the
pioneer
days,
people
grew
their
own
food,
caught
their
own
fish,
and
collected
their
own
water．1．
People
also
used
rivers
as
roads,
travelling
on
boats．Traders
shipped
goods(货物)
to
people
from
other
areas.
.
When
building
many
factories
right
next
to
rivers
for
the
water’s
power
to
make
machines
work，some
people
choose
to
live
near
a
river
for
working．They
use
the
river
to
ship
large
goods,
and
some
of
them
work
at
these
factories
where
power
factories
provide
electricity
to
homes
and
businesses．3．
.
Who
wouldn’t
want
to
live
near
a
river?
Some
people
are
nervous
about
living
near
rivers
because
rivers
can
cause
floods(洪水)．Every
once
in
a
while,
floodwaters
rise
higher
than
a
house,
ruining(泡坏)
many
things
in
the
house．4．
Such
waste
causes
water
to
smell
bad
and
pollutes
the
crops
(庄稼)
we
eat．Water
and
crops
in
polluted
areas
can
make
people
very
sick.
How
do
people
decide
where
to
live?
5．
Rivers
can
provide
jobs
and
fun
activities
in
a
beautiful
place．However,
those
living
by
rivers
should
be
willing
to
accept
possible
problems
as
well.
