我原来以为保险丝被烧断是技工的责任，但是我现在意识到自己错了。

I thought the technician was to blame for the blowing of the fuse, but I see now that I was mistaken.

伦敦北的保险丝烧断使火车延误一个多小时，而前一夜，另一条线的旅客因为电线断裂而被滞留六个小时。

A blown fuse in north London delayed trains for over an hour. The night before, travellers on another line had been stranded for six hours, thanks to broken power cables.
