单选题Elephants are the biggest animals that live on land (some whales are bigger than elephants but whales live in the sea), when born a baby elephant weighs 91 kilograms. That is the weight of a grown man. It is about 91 centimeters high. When it reaches the age of six years, it is about 183 centimeters high. (30) When it reaches the age of twelve years, it does not grow any more. It may then be 320 centimeters high. African elephants are bigger than Indian elephants. African elephants have much bigger ears. Elephants have very long noses which we call "trunks". No other animals have trunks as long as elephants. An elephant can use its trunk to smell things and it can also pick up things with the tip of its trunk. The tip of its trunk can be used like a hand. An elephant uses its trunk to feed itself. It likes to eat leaves, young juicy branches of a tree and fruit. It picks these with its trunk and puts the food into its mouth. When it wants a drink, it puts the tip of its trunk into water. It fills its trunk with water and then blows the water into the mouth. The elephant washes itself in the same way. It fills its trunk with water and then blows the water over itself. Two of the elephant's teeth are very long and strong. They are called "tusks". They use their tusks to dig up small trees and to dig in the ground for water. Elephants also use their tusks to lift heavy logs of wood. In some countries men catch wild elephants and teach them to work. After a while they are no longer wild. They become tame. They become very obedient. They do what their masters tell them to do. All day long they work patiently in the hot sun. They pull trees along and lift heavy logs. No animal is stronger than an elephant. Elephants have very strong legs. Their legs are like trees. They usually walk slowly because they are so big, but they walk very quietly.

单选题Much unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction. Computers are often used as part of automated (自动化的) production systems requiring a least possible number of operators, causing the loss of many jobs. This has happened, for example, in many steelworks. On the other hand, computers do create jobs. They are more skilled and better paid, though fewer in number than those they replace. Many activities could not continue in their present form without computers, no matter how many people are employed. Examples are the check clearing (交换) system of major banks and the weather forecasting system. When a firm introduces computers, a few people are usually employed in key posts (such as jobs of operations managers) while other staff are re-trained as operators, programmers, and data preparation staff. After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees. This decrease is sometimes balanced by a substantial increase in the activity of the firm, resulting from the introduction of computers. The attitudes of workers towards computers vary. There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult. On the other hand, many workers regard the trend toward wider use of computers inevitable. They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs. This view was supported by the former British Prime Minister, James Callaghan in 1979, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long run.
