переведите грамотно пожалуйста!!! In
Malaysia, parents don’t seem to have enough money to pay for their children’s
education in the universities or college. (0) So,
by working part-time, children can help their parents. (1) at the same time
, by doing part-time jobs, students can earn their own money. (2) what’s
more, they can learn to be independent. This will help them when they grow
up in the future.

In Japan, about 30% of teenagers wok part-time.
Some of them have to work to make money for college. (3) on the other hand  ,
most students who have jobs want to spend money just for fun. They work to buy
things (4) such as clothes, electronic products and groceries.

In my country, it is not so common for teenagers to
work. Some teenagers, (5 for example, want to work to help their
parents to pay for the education. Some take part-time jobs after school (6) because
they want to become economically independent from their parents. (7 besides ,
they want to earn money to buy some things they want.

   Teenagers are independent of their
parents. (8) but ,
they will value what they have now.

      What I want to say is
(9) Although working part-time has some bad points for students,
it is also gives them valuable experience for whatever they do later in
life.

    Teenagers can work (10) as long
as they have time to prepare their homework well.
