A wave of recent research has pointed to the risks of overpraising a child. But for parents, drawing the line between too little praise and too much has become a high-pressure balancing act.overpraise:过度夸奖 Cara Greene, a mother of three children ages 1 to 8, is wary of deliberately pumping up her... 阅读全文
