女排精神的“秘密”

    在多年执掌美国等国家女排后，2013年郎平再次担任正处于低谷的中国女排主教练。然而，郎平才出手就招来质疑：以前大小国际比赛都是国家一队，怎敢让二队上？可郎平却是“大国家队”的思路，打破两队界限，整个国家队因此被激活。

    春节七天封闭训练，历来如此，包括晚上不准玩手机等。但2014年春节，国家女排破例休息三天；手机可玩，但有条铁律：不能影响第二天训练。主攻队员朱婷，家境一般，体质较弱，郎平就从美国给她买奶粉。同时，由助理教练、国外体能训练师等组成的辅佐团队，首次超过国家队队员人数。负重下蹲体能训练，以往总认为练得越刻苦越好，可郎平及其团队却强调适可而止，以防关节损伤。

看完上述材料，郎平的这些做法让你感触最深的两点是什么？

      We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people.
Why do we go wrong about our friends? Sometimes people hide their real meanings when they say something. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, “You're a lucky dog.” That's being friendly. But “lucky dog”? There's a bit of envy(嫉妒) in those words. Maybe he doesn't see _it_ himself. But “lucky dog” puts you down a little. He may mean you don't deserve your luck.
      How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Do his words agree with the tone(语调) of voice? His posture(姿态)? The look in his eyes? Stop and think. If you spend the minute thinking about the real meaning behind one's words, it may save another mistake.
