且行且思：亲子沟通　通则不痛

张 烁

刚刚过去的母亲节，网友投票选出了“最伤妈妈的8句话”，很多人反思，这些话不能再说了，比如“别问了”“别管我”“真啰嗦”；与此同时，很多父母，尤其是孩子处于青春期的父母，也在为如何和孩子交流苦恼。

其实，无论是孩子的后悔还是父母的苦恼，都是亲子沟通出了问题。通则不痛，亲子沟通渠道畅通了，孩子就不会有揪心的后悔，父母也少了许多“说不明白”的烦闷。

亲子沟通的艺术，对父母而言，首先不能“一厢情愿”。教育孩子，爱之深，责之切，态度、语气容易失之过急，结果孩子越来越逆反。好话还得好好说，为人父母，要以孩子能听进去为最高目标。比如，营造一个平等、平和的气氛，给孩子一个辩解的机会，不要搞成“一言堂”；对于没搞清楚的问题，不要把猜测、推断当事实，让孩子感到自己总是被怀疑、被质疑；善于站在孩子的立场上考虑问题，意识到双方分歧也许只是考虑问题的角度不同；对事不对人，别把孩子“一棍子打死”，更不要“贴标签”、翻旧账，让孩子“翻不了身”……

亲子沟通的艺术，对孩子而言，首先不能“闭目塞听”。随着年龄增长，渴望独立的心跃跃欲试，从甩开父母的手，到自己拿主意、做选择，再到“父母那套都过时了”，很多孩子抗拒父母，甚至没有一个具体的理由，只是“一听唠叨就烦”。其实，父母也曾年轻过，孩子当下遇到的问题，父母也曾遇到过。当抗拒父母时，可以想想：不是为了自己好，父母怎么会这样？父母的话有没有道理，是不是有可以接受的部分？责怪父母不懂自己，是不是也因为自己不对父母敞开心扉？叮咛也许啰嗦，但这个世界上除了父母，还有谁能对自己这般放心不下……

父母和孩子，原本就血脉相通，为什么不能让沟通更顺畅些呢？

      About 150 years ago a German musician sat quietly at a concert in Vienna. They were playing for the first

time a new symphony (交响乐 ) he had composed (创作 ). At the end he turned to face the people at the

concert. They were clapping widely.   1   

     The musician was Beethoven, one of the greatest composers in the world. Deaf people have a hard time.

     Even as a child Beethoven did not have a happy life. His father was a singer. But he was lazy and drank a

great deal. When the boy was only four, his father decided to make a musician of him.   3  Whenever he did

not put his heart into his practice, his father would be hard on him.

      It is a wonder that the boy did not hate music.   4    When he was 17, he won high praise from Mozart,

a great Austrian composer. A few years later Beethoven went to Vienna to study under Haydn, another great

Austrian composer. Soon he was writing a great deal of music himself. But after one illness, he suddenly found

himself deaf. At that time he was only 31. What a blow it was to him!

      But this did not stop Beethoven. He went on composing.   5   During his life, he composed about 300

pieces. The surprising thing is that he wrote some of his best, his most beautiful pieces after he became deaf.

Many of them are known and loved all over the world.
