1.
教师先列举一些已经学过的动词开头的句子。
如：Put
the
picture
on
the
wall.
Close
the
window.
Take
the
second
turning
on
the
left.
告诉学生：这种动词开头的句子就是祈使句，它使用的场合就是当我们要告诉别人做什么时候
2.
介绍祈使句的否定式，就是在祈使句的开头加上‘don’t
/do
not’.
意思是告诉别人不做某事。
如：
Don’t
smoke
in
the
room.
Don’t
bring
your
dog
here
next
time.
有时为了显示说话的礼貌，通常会在祈使句的开头或结尾加’please’.
如：Please
help
me
carry
the
heavy
box.
Don’t
play
in
the
street,
please.

我们还可有用‘should’,
‘ought
to’
and
‘had
better’
来给建议，告诉人们最好怎么做。
三个词的区别
‘should’
and
‘ought
to’一般可以互换使用，‘had
better’
在语气上比前两者更强力。
如：You
should/ought
to
know
a
little
about
DIY.
You
had
better
buy
a
new
watch,
this
is
broken
注意：‘ought
to’
和‘had
( http: / / www.21cnjy.com )
better’
变成否定式就是在ought
和
had
后加not.
如：You
had
not
better
be
late
for
the
meeting.
You
ought
not
to
put
so
many
books
here.
