第2题:
[A] climbing [B] crawling [C] winding [D] sliding
本题考查动词辨析。空格处填入现在分词作句子状语,其逻辑主语是you。climb一般指“(向上)攀登,(吃力地向某处)爬”,如:climb up the stairs(爬上了梯子),climb through the window(从窗口爬了出来)。crawl指“(向前,身体接近地面的)爬行”,如:The baby is just starting to crawl.(宝宝刚开始会爬。)wind作不及物动词时,意为“(路,河等)蜿蜒,曲折而行”,如:The path wound down to the beach.(这条小路弯弯曲曲通向海滩。)slide指“滑行,滑动”。根据句意,你(驾驶者)缓慢地从大卡车旁往前开,由于路面滑,只能是“慢慢地滑过”。因此[D]正确。
