Those who had not sleepwalked in the past year were asked if they had as a child .

近年来没有梦游过的人则会被问及孩童时期是否曾经梦游过。

He 'd sleepwalked for the first time and apparently -- he couldn 't remember a thing -- his steering wasn 't skillful enough to avoid a leg-on collision .

这是他的首次梦游经历，很明显（他也记不清楚是怎么回事），他对方向的把控不够熟练，进而撞到了腿。
