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 ______.

The cheetah(猎豹)is best known for being the world’s fastest land animal, reaching speeds of just over 110kph for short period of time. However, many people know little else about this wonderful animal. The word cheetah probably comes from a Hindi word spotted animal. It is very similar to other cats but also has some obvious differences. Its body is much leaner than most cats and it has much longer legs.

People sometimes make a cheetah a leopard(美洲豹)because they both have spots, but in fact they are very different. A leopard is far heavier and more powerful, but also much slower. The cheetah’s spots cover most of its body except for its stomach and throat. The cheetah’s tail has spots and these become rings at the end of the tail.

An adult cheetah weighs between 35-65 kilograms and is about 80 centimeters high at the shoulder. The cheetah’s head is quite small and the eyes are quite high up. A black line runs from each eye down to its mouth and makes it look a little sad. It has high shoulders that help it to walk so gracefully.

Cheetahs are very fast but they are not very strong. They are not good fighters and will run away rather than fight another animal to protect their food. If they make a kill, it is sometimes taken away from them by stronger animals such as lions and leopard. These animals will kill their young if they get the chance. The cheetah is not a threat to humans at all. It will not attack humans and prefers to stay away from occupied areas.

1.Many people know that the cheetah________

2.The cheetah ________

3.Cheetahs will not fight another animal to protect their food because _______
