题目列表(包括答案和解析)
The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.
65. The purpose of the divers' journey to the deepest point on the earth was to find
A. if there are water currents, and life in the great depths
B. if people can stand the severe cold in the great depths
C. if there are steps in the great depths
D. if the telephone works well in the great depths
66. The divers set out early in the morning so that .
A. they could return to the surface during the day
B. they could see at the bottom of the ocean
C. they could avoid the cold at night
D. they could stay long at the bottom
67. As the divers went down to the ocean floor, the telephone .
A. kept working all the time
B. stopped working at a depth of 3,000 feet and began working again after they reached the bottom
C. stopped working at a depth of 3,000 feet and began working again at 30,000 feet
D. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth
68. On the ocean floor, the divers found that .
A. there was no life but some small dead sea creatures
B. fish were swimming as freely as they do near the surface
C. fish were not swimming freely in the dark water

Domestic (驯养的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (驯服的) 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 houses would show more of these chosen characteristics.
Modern day horse breeds 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 (矿井) 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, horse 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 from of rapid transportation helped cultures spread around the world.
【小题1】Before domestication horses were ______.
| A．caught for sports | B．hunted for food |
| C．made to pull ploughs | D．used to carry people |
| A．it is smaller than the Clydesdale horse | B．horse used to have gentle personalities |
| C．some horses have better shaped than others | |
| D．horses were of less variety before domestication |
| A．carrying heavy loads | B．changing farming methods |
| C．serving as a means of transport | D．advancing agriculture in different areas |
| A．why humans domesticated horses | B．how humans and horses needed each other |

| D．how human societies and horses influenced each other |
