题目内容

This great speed of light gives us some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light left the moon 1.3 seconds before it reached you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute. In some case, the light from one of tonight's stars started on its journey to you before you were bola.
Thus, if you want to be honest, you cant say" The stars are shining to night"? You have to say "The stars look pretty. They were shining four years ago but their light has just reached Earth".
Sunlight seems to ______ than the light of the moon.

A. have to travel a greater distance
B. move less quickly
C. travel much quickly
D. be less powerfull
