本题考查介词辨析。空格处填入的介词与动词rattle(象声词,“格格响,嘎嘎响”)搭配,其宾语是your car,主语是上文的snow, slush and chips of ice。选项中,onto表示“(朝某处或某位置运动)向,朝”,如:Move the books onto the second shelf.(把书移到第二层架子上。)against表示“逆着,与……相反”或“紧靠,倚”,如:We were rowing against the current.(我们划船逆水而上。)lean against the wall(斜靠着墙)。off意为down or away from a place“从(某处落下)”,如:I fell off the ladder.(我从梯子上跌了下来。)along意为“沿着,顺着”,如:They walked slowly along the road.(他们沿着公路慢慢走)。根据句意,应是“雪、泥和碎冰渣溅到车上,又格格作响地从车上掉下来”,因此[C]正确。
