滑木板

On every rail and gate, wet lay clammy,1 and the marsh-mist was so thick, that the wooden finger on the post directing people to our village -- a direction which they never accepted, for they never came there -- was invisible to me until I was quite close under it.

每一道围栏、每一扇大门上都是湿滑的潮气。沼泽地的雾气特别浓，我走到标杆底下，才看得见钉在上面的木板手指。

It seems today, it is a very simple invention: a piece of wood 50 * 50CM iron fixed in the roller wheels.

在今天看来，那是相当古朴的一项发明：一块50*50CM的木板固定在轮滑的铁轮子上。

一到星期天，成千上万轮滑爱好者便出现在木板人行道上，惊险地在行人之间穿梭滑行；这个时候，一些轮滑吉他手还会为日光浴者演奏小夜曲。

One day, the wooden boat sank when passing Huatuozui Shoal. He fell into water with other people in the boat. Thanks to a wooden board, he could swim to the bank and survived.

一天，他所乘小船路过磁器口滑拖嘴险滩时，木船被险滩打翻，他与全船人员落入水中，幸抓得一块木板得以逃生上岸而化险为夷。
