The first essential in elephant training is to assign to the animal a single mahout who will be entirely responsible for the job. Elephants like to have one master just as dogs do, and are capable of a considerable degree of personal affection. There are even stories of half-trained elephant calves who have refused to feed and pained to death when by some unavoidable circumstance they have been deprived of their own trainer. Such extreme cases must probably be taken with a grain of salt, but they do underline the general principle that the relationship between elephant and mahout is the key to successful training.
The most economical age to capture an elephant for training is between fifteen and twenty years, for it is then almost ready to undertake heavy work and can begin to earn its keep straight away. But animals of this age do not easily become subservient to man, and a very firm hand must be employed in the early stages. The captive elephant, still roped to a tree, plunges and screams every time a man approaches, and for several days will probably refuse all food through anger and fear. Sometimes a tame elephant is tethered nearby to give the wild one confidence, and in most cases the captive gradually quietens down and begins to accept its food. The next stage is to get the elephant to the training establishment, a ticklish business which is achieved with the aid of two tame elephants roped to the captive on either side.
When several elephants are being trained at one time, it is customary for the new arrival to be placed between the stalls of two captives whose training is already well advanced. It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions when it is eating normally, its own training begins. The trainer stands in front of the elephant holding a long stick with a sharp metal point. Two assistants, mounted on tame elephants, control the captive from either side, while others rub their hands over his skin to the accompaniment of a monotonous and soothing chant. This is supposed to induce pleasurable sensations in the elephant, and its effects are reinforced by the use of endearing epithets, such as 'ho! my son', or 'ho! My father', or 'my mother' according to the age and sex of the captive. The elephant is not immediately susceptible to such blandishments, however, and usually lashes fiercely with its trunk in all directions. These movements are controlled by the trainer with the metal-pointed stick, and the trunk eventually becomes so sore that the elephant curls it up and seldom afterwards uses it for offensive purposes.
The ill-treatment of an elephant during training______.
For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs. Coupled with the aging of the baby-boom (生育高峰) generation, a longer life span means that the nation's elderly population is bound to expand significantly over the next 40 years. By 2040, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions, and in law and business as well. "In addition to the doctors, we're going to need more sociologists, biologists, urban planners and specialized lawyers," says Professor Edward Schneider of the University of Southern California's (USC) School of Gerontology (老年学).
Lawyers can specialize in "elder law", which covers everything from masts and estates to nursing-home abuse and age discrimination (歧视). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. "Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree, will have a license to print money," one professor says.
Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was "really bored with bacteria." So she took a class in gerontology and discovered that she liked it. She says, "I did volunteer work in retirement homes and it was very satisfying."
"…Old is suddenly in"(Line 1, Para.1) most probably means______.
听力原文： Students want to find the best way to put information into their long-term memories. They want to keep the information later when they take a test. What is the best way to learn information so they can remember it when they want to？
When studying, you should read the whole lesson first. This gives you the whole picture in which to put the ideas. New information that fits into the whole picture is easier to remember than separate facts, You also learn faster if you look at headings, introductions, important words, summaries, conclusions, and anything else that helps to organize the material, which is easier to understand.
Then the second step is to study the parts. Think about how they fit into the whole picture.
If you have a lot to study, don't try to do the whole job at once. Learning should be spread out and spaced. This gives the information time to "sink in." You should study grammar three times, a half hour each time. That is better than studying for an hour and a half at one time. Even shorter study periods are better for vocabulary lists and other difficult material. To learn the most in a two-hour study session, study different kinds of material; a half hour on grammar, 15 minutes on vocabulary, 20 minutes on writing, and so on. The change will help to keep you interested.
You forget most quickly right after you read or hear something new. You should review right away so you won't forget, and if possible, explain it to someone else. When you review and test yourself on the material, you are being active; active learning is better than just reading or listening.
