5、now此刻,目前此刻,目前钢笔巨匠钢笔巨匠你知道Lszl Br?拉斯洛拜罗(注:匈牙利文)吗?也许你不知道,但你很可能每天都在用他的发明,你甚至可能现在手里还拿着它。拜罗(1899-1985)是圆珠笔的发明者。他出生在匈牙利(首都)布达佩斯。在 20 世纪 30 年代,当他担任报社编辑时,他几乎每天都要使用钢笔。但是,他必须一直给它加满墨水。那墨水没那么容易干,往往把报纸上搞得乌漆嘛黑。拜罗想要更好的笔。他的弟弟乔治帮他开发了一种特别的墨水。这种墨水很容易干。然后,他们开发了一种新型笔。在这个笔的尖端,有一个小球。小球移动时,把墨水带到纸上。他们把它称为“圆珠笔”。圆珠笔取得了巨大的成功,每个人都喜欢它。现在,世界各地数以百万的人每天都使用它。人们将一直记住拜罗的发明。今天,在很多英语国家,人们仍然用“biro”这个词代指任何类型的圆珠笔。
