北宋政治家、文学家王安石与好友王吉甫经常在一起谈论诗文。一天,王安石对王吉甫说:“我昨晚睡不着,做了条字谜:‘画时圆,写时方,冬时短,夏时长’,你猜是什么字?”王吉甫略一思索,便猜中了,也用谜语的形式回答道“:东海有条鱼,无头也无尾,更除脊梁骨,便是你的谜。”王安石听了,哈哈大笑,说:“你猜对了!”你知道这个字是什么吗?(答案就在书中的某一页,一定要动脑之后再去翻找哦。) Northern Song Dynasty politician and writer Wang Anshi and his friend Wang Jifu often talked about poetry. One day Wang Anshi said to Wang Jifu: “I could not sleep last night and made a crossword puzzle: ’Painting circles, writing the square, short winter, summer long’, what is your guess?” Wang Jifu a little thought, Then guessed it, but also replied in the form of a riddle “: there is a fish in the East China Sea, no head and no tail, more than the backbone, is your mystery. ” Wang Anshi listened, laughed and said: “ You guessed it! ”Do you know what the word is? (The answer is on a page in the book, and you must look after it.)
