假如我是发明家,我要发明盲人专用的铁竿。我家邻居老爷爷是个盲人,看见他拄着拐杖走路,我觉得他走路好辛苦。顿时,我心血来潮,也想学着老爷爷走路。一天下午,我在家里找了一块手帕,蒙住眼睛,右手拿起铁竿,学着爷爷的样子走路,左手配合着摸来摸去,谁知没有走几步就被石头绊倒了 If I were an inventor, I wanted to invent a blind rod for the blind. My grandfather neighbor is a blind man, saw him walking on crutches, I think he was walking very hard. Suddenly, I whim, but also want to learn grandfather to walk. One afternoon in the afternoon, I found a handkerchief at home, blindfolded my right hand and picked up the iron pole, learning to look like my grandfather walking with my left hand and touching it, and I realized that it was tripped over without walking a few steps
