May I have your attention, please?
My topic today is about copying other’s homework.
As we all know, some students copy other’s homework. On the one hand, we students have to
do masses of homework both at home and at school. Sometimes we do have some problems, too
hard to work out. On the other hand, lazy and uninterested in their lessons, some students copy others’
homework not only to finish the assignments but also please their teachers.
In a word, copying others’ homework is a bad habit. For one thing, it’s against the school rules.
Being students, we should be honest and work hard. If we have difficulties, we can turn to teachers and
classmates for help. For another, copying others’ homework too often, we will lose the ability that can
help us to think.
