为什么请家教?
Less take one class, either in primary or high school, as an example and divide it into three groups: the slow, the middle, and the fast learners. In the past, the slow learners used to have tutors. Today, however, it seems all of them have tutors for one reason or another.
The slow learners need tutors because they cant catch up with others with their own efforts. They have difficulty in understanding the teachers and doing their homework.. So after class tutoring is really important to them. But the problem is that they may become dependent on tutors and not work very hard in class.
As to the middle group learners, they worry about being surpassed and turn to tutors, too.
What about the fast learners? Though they are confident about their present position, they are not quite satisfied. They fix their eyes on a high goal. They desire to learn more in order to be more competitive later.
I think they have the right to have tutors, though I have no tutors.
