题目
题型:不详难度:来源:
Our physics teacher told us that light ________ faster than sound.
A.travelB.travelsC.is travellingD.has travelled

答案
B
解析

试题分析:根据题***结构,可知本句是一个宾语从句。根据宾语从句中如果从句是客观事实,不论主句是什么时态,从句都用一般现在时的用法, 本句中“光的速度比声音的速度快”是客观事实。故本题应该选B。
点评:实际上本题考查的是宾语从句的时态问题。宾语从句中的时态往往会受到主句时态的影响,但本题中考查的是特例,也就是如果从句是有关客观事实,则从句就用一般现在时。
