Review
1.
ask
students
to
look
at
the
picture
and
try
to
understand
the
meaning
of
comparative
forms
of
adjectives.
2.
Lead
the
Ss
to
compare
the
persons
in
the
picture.
3.
And
then
ask
students
to
use
the
other
work
to
compare
each
pair.
While
the
Ss
give
answers,
write
some
of
them
on
the
Bb.
1.
Yao
is
taller
than
Pan.
2.
Lily
has
shorter
hair
than
Mary.
3.
Sun
is

(设计意图：首先，通过图片和数字，让学生感受比较级的形式和意义；然后再用完整的句子呈现比较级，最后鼓励学生仿说例句，使用比较级描述人物特点。)
2.
Introduce
the
twins---
Tina
and
Tara
There
are
two
lovely
girls--
Tina
and
Tara.
They
are
twins,
but
they
are
different
from
each
other
in
some
ways.
Tina
is
more
outgoing
than
Tara.
She
is
friendlier
and
funnier,
too.
She
loves
sports,
so
she
can
jump
higher
and
run
faster
than
Tara.
But

more
hard-working
at
school.
And
Tara
is
smarter

Tina.
T:
Which
one
do
you

Why?
S:
I

she
is
funnier

3.
Ask
the
Ss
to
find
out
the
comparative
forms
from
the

and
then
try
to
find
the
changing
rules
of
the
words.
Some
Ss
say
add
“er”
“more”
to
the
words.
(设计意图：通过小短文和图片呈现比较级的用法，让学生找出比较级的形式并尝试发现比较的变化规则。)

and
the
Ss
can
take
the
opportunity
to
check
their

Grammar
focus
Review
the
grammar
box
.Ask
Ss
to
read
the
sentences
to
the
class
and
then
try
to
translate
the
sentences
by
themselves.
1.
Call
attention
to
the
word
“funny”,
circle
“y”
and
say
when
a
word
ends
in
y,
change
“y”
to
an
“i”
and
add
–“er”.
2.
Write
the
phrases
“more
athletic
than”.
Say,
when
you
complete
things
using
words
with
three
or
more
syllables,
you
use
the
word
more.
Practice:
happy,
outgoing,
short,
thin,
good.
(设计意图：呈现规则之后还是需要学生更进一步的理解和运用，因此要求学生大声朗读和Grammar
Focus中的句子，将规则和实际应用结合起来，然后再为学生呈现口诀，他们觉得有趣，就可以记得更好一些。)
Step
VI.
Exercise
1.
Ask
students
to
translate
the
two
sentences
and
try
to
find
out
the
similarities
of
them:
(1)
Are
you
as
friendly
as
your
sister?______
(2)
Does
Tara
work
as
hard
as
Tina?_______
Summary:
as……as
“同…一样…”中间用形容词或副词的原级。
2.
Ask
the
Ss
to
finish
sentences
in
3a
and
check
the
Ss’
answers.
For
example,
-
Is
Julie
as
tall
as
you?
-
No,
she
isn’t.
She’s
taller
than
me.
3.
Think
of
yourself
two
years
ago.
Write
about
how
you
are
different
now.
For
example,
-
Are
you
taller?
-
Yes,
I
am.
I’m
taller
now
than
I
was
two
years
ago.
In
this
way,
the
Ss
will
have
chances
to
use
general
questions
and
negative
sentences.
3.
Look
at
the
pictures
as
careful
as
possible
and
find
out
the
differences.
The
more,
the
better.
For
example:
The
man
is
taller
than
the
girl.
Step
V.
Practice
1.
Pairwork

A:
Who
is
smarter,
your

or
father?
B:
I
think
my
mother
is

2.
Listen
to
some
songs
with
comparative
forms:
Hope
She'll
Be
Happier
Maybe
the
lateness
of
the
hour
Makes
me
seem
bluer
than
I
am
But
in
my
heart
there
is
a
shower
I
hope
she’ll
be
happier
with
him
Maybe
the
darkness
of
the
hour
Makes
me
seem
lonelier
than
I
am
But
over
the
darkness
I
have
no
power
I
hope
she’ll
be
happier
with
him

Tidal

(设计意图：通过这两个小的活动，在轻松有趣的氛围中，引导学生去进一步感知和运用比较级。)
Step

Homework
1.
What
are
the
differences
between

亮点：语法知识的学习和记忆，对学生来说有一定的难度，如何能使学生学得轻松，就需要设计好活动。首先，通过图片和数字展示比较级的原来，通过句子展示如何比较级来表达比较人或物。然后，通过更多的例子，让学生自己去发现总结规律，再为学生展示变化规则，为了让学生更好的记忆，使用简短的口诀。在练习环节，设计学生感兴趣的内容或者学生熟悉的人，来使用比较级表达自己的观点。
