Parents, especially those of teenagers, care about their children's education more than anything.They usually do everything for their children. Many of them spend most of their free time helping their children    studies. If they have no time or cannot do it(they), they would hire family teachers or send their children to after-class schools. It seems as if a better education is all that parents expect for their children.
How can we explain the present situation? First, many parents have  (realize) that future success  (depend) more and more on skills and education., in such a competitive society there are both losers and  . Those who have better skills and more knowledge will have  (chance).
In my  , it is important to learn to succeed, but the  (one) thing to learn is how to survive, how to be a qualified citizen. If these are included in a good education, the children will surely have a bright future and be healthy in body and mind.
