“小博士”

  黄炜是北京翠微路小学六年级的学生他知道的东西可多了同学们都叫他小博士

  “小博士”有个习惯:对什么事都要打破沙锅问到底。比如,他看到闹钟一上弦就走,就想找出它的奥秘。于是,他把家里的闹钟悄悄地拆开,观察内部结构;他又看到半导体收音机能发出声响,就把它打开,仔细研究。现在,家里的收音机坏了,他还能修理哩!

  黄炜喜欢阅读自然科学读物。他常常把学到的知识绘声绘色地讲给同学听:从宇宙、地球,讲到古猿进化到人;从人们最初用手指计数,讲到现在的大型计算机;从古人梦想的空中驾云,讲到宇宙飞船,外星人,飞碟和星际旅行……他还善于观察周围的事物,从天空中的风云变幻,到地上的蚂蚁筑窝……正是因为黄炜有勤学好问的精神和细心观察的好习惯,使他成为了同学们当中的“小博士”。
