As
we
know
sweet
food
such
as
ice
cream,
chocolate
and
cakes,
it
contains
a
lot
of
sugar.
And
so
does
cola
and
other
kinds
of
soda.
the
fried
food
in
KFC
or
MC,
also
has
a
lot
of
fat.
Some
of
them
are
sweet.
Some
of
them
are
yummy.
For
example,
I
like
chocolate
very
much.
It
is
sweet
and
tasty.
It
makes
me
happy.
But
too
much
chocolate
is
bad
for
my
teeth.
I
think
I
should
only
eat
a
little
at
a
time.
What
about
you?
Do
you
like
any
of
them?
Can
you
say
something
about
it?
Now
would
you
please
pause
the
video
and
say
it
loudly.

Boys
and
girls,
junk
food
or
healthy
food.
We
will
all
be
healthy
if
we
eat
them
in
a
right
way.
So
let’s
see.
Besides
sugar
and
fat,
our
body
also
needs
protein.
Look,
these
food
contains
a
lot
for
protein.
Do
you
like
them?
Yes，me
too.

also

us
strong.
Every
day,
we
can
have
some
of
them.
What
else?
Yes，we
Chinese
like
rice,
steamed
buns
and
noodles.
Western
people
like
bread.
These
are
all
carbohydrate.
It
gives
us
energy.
We
eat
a
lot
of
them.
Boys
and
girls,
think
about
your
daily
meals,
what’s
missing?
Yes,
fruits
and
vegetables
are
important.
It
gives
us
vitamin.

makes
us
young
and
beautiful.

all
know
what
a

is.

check
7)
So
let’s
sum
up
the
grammar
points.
8)
Now
I
think
you
can
tell
me
if
our
old
friend
Sam
has
a
healthy
diet?
Do
you
still
remember
the
cartoon
time
and
finish
the
shopping
list?
What
did
they
buy?
How
much
did
they
buy?
Pause
the
video,
look
into
your
books
and
finish
the
list.
OK.
Have
you
done.
Let’s
check.
First,
Sam
wanted
the
cola.
His
mum
told
him
to
take
a
small
bottle.
How
much
is
a
small
bottle?
Yes,
that
is
a
little.
Next,
they
bought
a
big
bag
of
rice.
I
think
it
is
a
lot.
Do
you
agree?
So
we
can
also
say,
they
bought
a
lot
of
rice.
At
last
,
they
had
a
fish
and
it
is
big.
Well
done.
Now
can
you
tell
if
Sam
has
a
healthy
diet?
Yes,
I
think
so.
He
only
has
a
little
cola
at
a
time.
9)
Boys
and
girls
,
after
shopping
Sam
lost
his
fish
on
the
way
home.
He
was
very
sad.
His
mum
wanted
to
cook
something
good
for
him.
But,
Look!
Accidents
happens
easily
in
the
kitchen.
What’s
that?
There
‘s
a
little
mouse
in
the
house.
Sam’s
mother
shouts,
“Get
out!
Get
out!”
Here,
