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(距离) 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(太阳光) 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.”Light speed is ______ sound speed.
| A．as fast as |
| B．a million times slower than |
| C．about millions of times faster than |
| D．about a million times faster than |
If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that ______.
| A．you can hear the sound before you see the smoke |
| B．the sound does not travel as fast as light |
| C．the sound will reach you before the man fires |
| D．sound travels about a million times faster than light |

Travelling is one of the most important activities and people have been interested in it for many years. Modern traffic develops fast, so travelling to different places has become much faster than before. Staying healthy while travelling can make your trip happier. But do you know how to keep healthy during a trip? The following information may be useful to you.
Before leaving
Wear comfortable shoes, a hat and sunglasses.
Take some necessary medicine with you. They can be used when you get sick or have other problems.
