Some good advice
A. Nobody was born stupid. Maybe you haven't got right ways of study yet. Ask the
teachers or classmates for help if you have any questions.
B. Your classmates may not laugh at you. If you don't like their laugher, you should talk
to them about your feelings. They might understand you. And you had better be more
easygoing and be their friend.
C. If you feel unhappy, go to have a good sleep and you will forget everything unhappy.
D. Don't be afraid. You should tell your parents or teachers at once. Don't go out alone
then.
E. Let your parents know your friends are nice. You learn a lot from them as well as have
fun with them. You study with them outside, too.
F.Tell your mother you need her company sometimes. Also you should do some housework
with your mother so she can finish her work quickly. Try to understand her, too. |
