The word photography was first used in 1839. However, at that time the subject (被拍对象) had to keep still while a picture of it was taken. Few people had ever tried to take photos of moving subjects. The first man to do so was Eadweard Muybridge, a world-famous photographer. He created the first moving picture.

When a horse is running, do all four hooves (蹄)ever leave the ground at the same time? That was the bet that a gentleman called Leland Stanford had with some of his friends. Most people believed that a horse always had one hoof on the ground, but Stanford didn’t think: so. Because a horse’s legs are moving so fast, it’s impossible to tell just by looking. Stanford needed a way to record the movement of a running horse. In 1872, Leland Stanford offered Eadweard Muybridge $25,000 to find the answer. Muybridge had no idea if he could successfully set up and perform an experiment to settle (解决) the bet, but he thought he should give it a try.

In 1878, after years of experiments, Muybridge got what he wanted. He had a sequence (连续) of 12 images (图像), and one of them clearly showed all four of the horse’s hooves were off the ground at the same time. In the end Muybridge collected his well-earned $25,000 from Stanford.

Though Thomas Edison is usually considered as the person who created the first cine-camera (电影摄影机) in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison’s invention.

Should We Keep Animals In Zoos?

Zoos are popular places in communities around the world. They're places where people can learn about wild animals by seeing them up close. Some people, though, believe zoos aren't good for animals. They think wild animals should only live in the wild.

1.

Wild animals have been kept in cages for thousands years. Over time, people began speaking out about the practice of keeping animals in zoos. The rise of animal rights movement and groups have led many to question whether or not zoos are right.

2.

Zoos provide care for animals that they wouldn't receive in the wild. Animals are fed a healthy diet in zoos. Also, zoos have veterinarians who provide medical care for hurt or sick animals that would often be left to die in the wild. In some cases, zoos help animals to live longer.

3.

Though many animals live longer in zoos, some mammals live longer in the wild. Elephants live near twice as long in the wild as they do in zoos. Scientists believe the causes for this include elephants in zoos becoming stressed and depressed when they are forced to live in small spaces.

4.

It may seem like a good thing that zoos set animals back into the wild, but there are often problems with this practice. Zoo animals don't learn hunting skills since they are fed by zookeepers. They also have no idea to stay away from predators, cars or hunters in the wild.

5.

How much do zoos actually teach people about animals? A 2014 study showed that only 1000 out of 3000 children who visited a zoo learned something new. Groups such as PETA believe the biggest thing children learnt at zoos is that it's fine to keep animals in cages instead of in the wild.

A. Unable to go back

B. Caring for animals

C. Animals in the world

D. Spiritual problems

E. Rise of animal rights

F. The wrong lessons
