閱讀理解

  Light travels at a speed (速度) which is about a million times faster than that of sound. In one second, light travels about 300,000 kilometers, but sound travels only 340 meters. You can get some idea of this difference by watching the start of a running match. If you stand quite far away from the starter (發(fā)令員), you can see smoke come from his gun before the sound reaches your ears.

  The fast speed of light produces 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 rays (射線) left the moon 1. 3 seconds before they reached you. The nearest star is so far away that light which you can see from it tonight started to travel to you 4 years ago at a speed of nearly 2 million kilometers every minute. The light from some of tonight's started on its journey towards you even before you were born.

  So, if we want to be honest (誠實(shí)的), we can not say, “The stars are shining brightly tonight.” We have to say. “The stars look nice. They were shining four years ago but their light has just reached our earth.”

C.sound travels less fast than light

D.the sound of the gun reached you at the same time with the light of the smoke

3.Sunlight obviously (明顯的) ________ than the light of the moon.

[  ]

A.has to travel a greater distance (距離)

B.moves less quickly

C.travels much more quickly

D.is less powerful

4.The scientific way of saying ``The stars are shining brightly tonight" should be ________.

[  ]

A.the stars have been shining all the time

B.the stars seen tonight will be shining four years later
