Sound travels in the same way as light___.AdoesBdoCtraveled

问题描述:

Sound travels in the same way as light___.AdoesBdoCtraveled

选A。
相当于sound travels in the same way as light travels. does 相当于travels.因为travel已出现了,为了避免重复,用does来代替。而且这个句子的时态是一般现在时。看travels就知道了,所以B和C都不符合题意。

a

A
句中用SOUND和LIGHT来做比较.所以要形式前后一致.如果有TRAVELS的话,也可以选.但这里没有,就用DOES代替TRAVELS.

A: does
Sound travels in the same way as light___ (travels. 因为跟前面重复, 所以用does 代替)。
