2学情分析
Students
have
learned
the
basic
knowledge
of
comparatives
of
adjectives
and
superlatives
of
adjectives.
But
they
could
hardly
name
out
the
rules
of
how
adjectives
are
changed
into
their
comparatives
or
superlatives
systematically.
And
they
even
feel
puzzled
about
some
changes
of
some
adjectives.
3重点难点
For
the
important
points,
students
have
to
know
the
several
rules
on
how
to
change
adjectives
into
their
comparatives
and
their
superlatives.
For
the
difficult
points,
students
may
feel
confused
about
some
changes,
for
example,
those
words
ended
by
vowel+consonant
should
double
their
consonant
and
add
-ed
or
-est
after
it.
But
for
some
words,
it
is
changed
in
a
different
way.
