analysis
Section
A的主要教学活动为1a,
2b和3。本节课主要学习形容词的比较级、最高级这一重点语法，它是本话题的重点也是难点，建议至少用两节课完成Section
A
的教学。
本节课通过Michael
和Wang
Wei
的对话，引出农村和城市的对比，最终学习本节课以及整个话题的重点：形容词的比较级和最高级。课本中设计了农村和城市对比的图片和农场里各种不同的动物的图片，这些跟日常生活密切相关，能引起学生的联想和兴趣。在设计这堂课的时候，教师可以根据实际情况，增加模拟真实的情景让学生有更加真实的感受，在活动中自然习得语言。

Teaching
Reflection
It’s
easy
for
the
students
to
master
new
words
and
adjectives.
But
the
grammar:
comparative
and
superlative
degrees
of
adjectives
is
very
difficult
for
students.
At
first,
students
should
master
the
rules,
then
they
should
know
how
to
make
a
sentence
with
it.
At
last,
they
can
use
it
in
daily
life.
Every
step
is
not
easy.
So
teacher
should
create
more
situations
to
practice
it.
