三、阅读理解
Six
children
were
in
the
hospital.
They
got
infected
with
E.
coli
(感染了大肠杆菌).
They
were
very
sick,
but
the
doctors
didn’t
know
what
caused
the
infection.
They
called
Dr.
Richard
Besser.
They
were
sure
he
would
find
out.
First,
Dr.
Besser
carefully
studied
the
E.
coli
the
sick
children
had.
He
looked
at
the
bacteria’s
(细菌的)
DNA．The
DNA
showed
that
this
kind
of
E.
coli
was
dangerous
to
humans.
Dr.
Besser
knew
this
kind
of
E.
coli
could
move
from
animals
to
humans.
Perhaps
the
children
had
touched
animals
that
carried
the
bacteria.
Dr.
Besser
found
other
E.
coli
cases
(病例)
in
the
place
where
the
children
lived.
But
it
didn’t
make
the
answer
clear.
Dr.
Besser
then
made
a
list(清单)
of
what
the
sick
children
had
eaten.
They
had
all
had
cheese,
apple
juice,
and
fish.
He
then
made
a
list
of
what
healthy
children
in
the
same
place
had
eaten,
and
compared
the
two
lists.
They
had
had
the
cheese
and
fish,
but
not
the
apple
juice.
Dr.
Besser
went
to
where
the
apple
juice
was
made.
He
saw
that
there
were
animals
around
the
apple
trees,
and
he
saw
the
workers
using
dirty
fallen
apples.
More
importantly,
he
saw
they
didn’t
wash
the
apples
before
the
juice
was
made,
and
they
didn’t
heat
(加热)
the
juice
to
kill
the
bacteria
in
it.
Dr.
Besser
then
knew
it
was
the
apple
juice
that
made
the
children
sick.
26．Why
did
the
doctors
call
Dr.
Richard
Besser?
A．To
give
advice.
B．To
say
thank
you.
C．To
ask
to
join
him.
D．To
ask
him
for
help.
27．What
does
the
underlined
word
“They”
refer
to?
A．The
sick
children.
B．The
healthy
children.
C．The
doctors.
D．The
animals.
28．What
made
the
six
children
in
the
hospital
sick?
A．Fish.
B．Animals.
C．Apple
juice.
D．Cheese.
29．Which

following
things
happened

other

coli
cases.
B．Dr.
Besser

somewhere
after
a
comparison.
C．Dr.
Besser

a
list
of
what
the
sick
children
are.
D．Dr.
Besser
found
the
E.
coli
he
studied
was
dangerous
to
humans.
30．What’s
the

title
for
the
passage?
A．Good
and
bad
bacteria
B．Looking
for
the
answer
C．Six
children
in
the
hospital

四、短文选词填空
if；properly；information；use；who；glass；sick；enough；made；us
We
need
to
know
how
much
of
what
food
to
eat
to
be
healthy.
Here
is
a
picture
about
food
groups
and
why
they
are
good
for
our
health.
It
is
important
to
understand
how
food
is
used.
When
we
eat
food,
our
bodies
31．
the
food
to
make
energy.
32．
we
are
eating
the
correct
food
and
the
correct
amount
of
the
food,
we
will
have
enough
energy
for
our
bodies
and
minds
to
work
properly.
It
is
necessary
to
read
the
labels
（标签）
on
the
foods
in
a
shop
as
well.
The
labels
tell
33．
what
the
food
has
in
it.
They
give
us
34．
about
how
healthy
the
food
is.
There
are
many
people
who
do
not
eat
enough
right
food.
This
could
be
because
they
are
too
poor
to
buy
the
right
food.
These
people
may
have
what
we
call
malnutrition（营养不良）.
Children
35．
have
malnutrition
do
not
grow
properly
and
they
can
not
concentrate（集中精力）at
school.
If
things
are
very
bad,
they
can
become
36．
and
even
die.
Malnutrition
is
a
great
problem
in
some
poor
parts
of
Asia
and
Africa.
It
is
also
important
to
drink
lots
of
water.
Our
bodies
are
37．
up
of
about
76%
water.
We
need
to
drink
six
to
eight
38．
of
water
a
day.
Water
keeps
our
skin
healthy.
It
also
makes
sure
that
our
bodies
work
properly.
If
we
do
not
drink
39．
water,
we
can
get
headaches,
stomachaches
and
our
kidneys
（肾脏）
will
not
work
normally.
If
we
want
to
have
minds
and
bodies
that
work
40．,
we
need
to
make
sure
that
we
eat
correctly.
五、完成句子
41．我工作了一整天，回到家感到筋疲力尽。
I
had
been
working
all
day
and
I
_____
after
I
got
home.
42．那是如此漫长的一个旅程，每个人都筋疲力尽了。
It
was
such
a
long
journey

43．非经允许，请勿触摸展品。

the
exhibits
