If parents go on doing this, the children will only learn to open their mouths to be fed and stretch out (伸出) their arms to be 7 every day. When the children grow up, they will be able to do 8 , and they won't even find a 9 . Parents should teach the children 10 to do housework because it can help them start good habits of working by themselves. | |
