To be sure, it would have been more reasonable to abolish b where it was not pronounced, and this is what the related languages did (cf. German Lamm/Dutch lam and German dumm/Dutch dom for Engl.

可以肯定的是，取消不发音的b会更合理，其它语言也这样做了（参见德语Lamm/荷兰语lam和德语dumm/荷兰语dom对应英语lamb和dumb），但英语不喜欢放弃拼字法上遗留的遗迹。

As for practicing with "robots" the article states that Bruce Lee "works" on stuffed dumm ies... I wonder how fast and how varied their counter attacks are, and if they move around him quickly?

至于和“机械呆板的人”练习，文中声称李小龙和呆板的人“合作”……我倒想知道当他们的反击有多快和变化多端，还有他们绕着李小龙转时是否迅速？
