(travel) faster than sound. 相关知识点: 试题来源: 解析 1.travels 考查动词时态。根据句子结构,该宾语从句是叙述永恒不变的 "真理" ,时态应为一般现在时, "light" 是主语,所以谓语动词应为三单形式 "travels" 。句意:过去的人们不知道为什么光比声音传播得快。故正确答案为:travels。
解析 travels 本题考查宾语从句的时态。在宾语从句中,当从句描述的是客观真理、自然现象等时,无论主句是什么时态,从句都要用一般现在时。“光比声音传播得快” 这是一个客观事实,所以即使主句 “wanted” 是一般过去时,从句中 “travel” 仍要用一般现在时的第三人称单数形式 “travels”。
