那天,爸爸给我讲了一个寓言故事: 很久以前,有一把锁和一根大铁棍,铁棍想把锁打开,就使足力气去开锁,却怎么也打不开。这时,来了一把小小的钥匙,只见它轻轻一拨,就把锁打开了。铁棍很不服气地问钥匙:“为什么你那么小都能开锁,而我这么大却不能打开这把锁呢?”钥匙回答说:“因为我触动了它的心。” That day, my father told me a fable: a long time ago, a lock and a large iron bar, iron bar to open the lock, it is sufficient effort to unlock, but how can not open. At this time, came a little key, saw it gently dial, put the lock opened. Iron sticks unconvincingly ask the key: “Why can you unlock so young, and I can not open the lock so much?” The key replied: “Because I touched it.”
