高一英语单项填空中等难度题查看答案及解析

Light travels at a speed which is about a million times faster than the speed of  sound. You can get some idea of this difference by watching the start of a race. If    you stand some distance away from the starter, you can see smoke from his gun      before the sound reaches your ears.

This great 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 left the moon 1.3 seconds before they reached you. The nearest star is so far  away that the light that 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 cases, the    light from one of tonight’s stars had started on its journey to you before you were born.

Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We   have to say instead, “The stars look pretty. They were shining four years ago, but    their light has only just reached the earth.”

1. Light speed is ______ sound speed

2.If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that ______.

3.Sunlight obviously (明显地) ______ than the light of the moon

4.The scientific way of saying "The stars are shining tonight" should be ______.
