参加本刊2002年12月“爱迪生接班人”竞猜的读者,人数首次超百,与以往一样,90%以上是男生。为此,编辑吁请女生也踊跃参与这种益智问答。在读者寄来的信件中,约有30%经过涂改,否定了原本正确的答案,他们与奖品擦肩而过,十分可惜。不要灰心,有奖竞猜陆续有来,机会大大的有。答案 For the first time readers who participated in the quiz of “Edison Successor” in December, 2002, as before, more than 90% of them are boys. To this end, the editor urged the girls to participate actively in this puzzle quiz. About 30% of the letters sent by readers have been altered to negate the original correct answer. It is a shame that they passed the prize. Do not be discouraged, winning contentions come one after another, chances are big. answer
