Question

—Do you know sound travels very fast?
　一Yes. But light travels _________ sound.

A． much faster than	B．a little faster than
C．as fast as	D．slower than

Answer 1

A

试题分析：句意：你知道声音传播很快吗？知道，但是光比声音传播要快得多。Much faster than, 快得多，much用来修饰faster,表程度；a little faster than,快一点点；as fast as和…….一样快；slower than比……要慢。很明显A符合题意。
