Domestic (馴養(yǎng)的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (馴服的) enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.

Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.

As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals’ genes. So as the domesticated horses reproduced, they passed the characteristics on to their young. Each new generation of horses would show more of these chosen characteristics.

Modern-day horse breeds（種類） come in a wide variety of shapes and sizes. This variety didn’t exist in the horse population before domestication. The Shetland horse is one of the smallest breeds— typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts (礦井) with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.

The domestication of horses has had great effects on societies. For example, horses were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new form of rapid transportation helped cultures spread around the world.

A. caught for sports                           B. hunted for food

Bill Javis took over our village’s news-agency at a time of life when most of us only wanted to relax. He just thought he would like something but not too much to do, and the news-a??gency was ready-made. The business produced little enough for him, but Bill was a man who only wanted the simplicity and order and regularity of the job. He had been a long-serving sailor, and all his life had done everything by the clock.

Every day he opened his shop at 6:00 a. m. to catch the early trade; the papers arrived on his doorstep before that. Many of Bill’s customers were city workers, and the shop was convenient for the station. Business was tailing off by 10 o’clock, so at eleven sharp Bill closed for lunch. It was hard luck on anybody who wanted a paper or magazine in the after??noon, for most likely Bill would be down on the river bank, fishing, and his nearest competitor was five kilometers away. Sometimes in the afternoon, the evening paper landed on the doorway, and at 4 o’clock Bill reopened his shop. The evening rush lasted till seven, and it was worthwhile.

He lived in a flat above the shop, alone. Except in the very bad weather, you always knew where to find him in the af??ternoon, as I have said. Once, on a sunny afternoon, I walked home along the river bank from a shopping trip to the village. By my watch it was three minutes past four, so I was aston??ished to see Bill sitting there on his little chair with a line in the water. He had no luck, I could see, but he was making no effort to move.

“What’s wrong, Bill?” I called out from the path.

For answer, he put a hand in his jacket and took out a big, golden object. For a moment I had no idea what it could be, and then it suddenly went off with a noise like a fire en??gine. Stopping the bell, Bill held the thing up and called back, “Ten to four, you see, and this is dead right.”

I had never known anyone carrying a brass alarm clock round with him before.
