If you want stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most our brains are not getting enough exercises—and as a result, we are ageing unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down.
With a team a colleague (同事) at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.
" Computer technology enabled the researchers to obtain precise (精确的) measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. " The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional facilities.
Contraction of front and side parts—as cells die off—was observed in some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head.
The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm workers, bus drivers and shop assistants.
Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to maintain good blood circulation is through using the brain, " he says, "Think hard and engage in conversation. Don't rely on pocket calculators.
The team of doctors wanted to find out______.
A．how to make people live longer
B．the size of certain people's brains
C．which people are most intelligent
D．why certain people age sooner than others

听力原文： The eight elephants from Thailand destined for zoos in Sydney and Melbourne are due to arrive later this year.
Wildlife campaigners have insisted that scientific evidence has proved that elephants in zoos don't breed well and suffer a wide range of health problems. On top of that, it's claimed they die at a younger age than those living in the wild or kept in parks.
The government in Canberra is allowing these Asian elephants into Australia as part of a conservation program that it believes will help safeguard the species. The population of these magnificent animals has been reduced over the past century. It's estimated that fewer than 34,000 now remain across a dozen countries.
What can we know about the elephants in zoos？
A．They generally breed well.
B．They may not suffer health problems.
C．They may die relatively young.
D．They are cleverer than the wild elephants.

The modern multinational corporation is described as having originated when the owner-managersof nineteenth-century British firms carrying on international trade were replaced by teams ofsalaried managers organized into hierarchies. Increases in the volume of transactions in such firmsare commonly believed to have necessitated this structural change. Nineteenth-century inventionslike the steamship and the telegraph, by facilitating coordination of managerial activities, aredescribed as key factors. Sixteenth-and seventeenth-century chartered trading companies, despitethe international scope of their activities, are usually considered irrelevant to this discussion: thevolume of their transactions is assumed to have been too low and the communications andtransport of their day too primitive to make comparisons with modern multinationals interesting.
In reality, however, early trading companies successfully purchased and outfitted ships, built andoperated offices and warehouses, manufactured trade goods for use abroad, maintained tradingposts and production facilities overseas, procured goods for import, and sold those goods both athome and in other countries. The large volume of transactions associated with these activitiesseems to have necessitated hierarchical management structures well before the advent of moderncommunications and transportation. For example, in the Hudson’s Bay Company, each far-flungtrading outpost was managed by a salaried agent, who carried out the trade with the NativeAmericans, managed day-to-day operations, and oversaw the post’s workers and servants. Onechief agent, answerable to the Court of Directors in London through the correspondencecommittee, was appointed with control over all of the agents on the bay.
The early trading companies did differ strikingly from modern multinationals in many respects.They depended heavily on the national governments of their home countries and thuscharacteristically acted abroad to promote national interests. Their top managers were typicallyowners with a substantial minority share, whereas senior managers’ holdings in modernmultinationals are usually insignificant. They operated in a pre-industrial world, grafting a systemof capitalist international trade onto a pre-modern system of artisan and peasant production.Despite these differences, however, early trading companies organized effectively in remarkablymodern ways and merit further study as analogues of more modern structures.
The author’s main point is that______
A．modern multinationals originated in the sixtenth and seventeenth centuries with the establishment of chartered trading companies
B．the success of early chartered trading companies, like that of modern multinationals, depended primarily on their ability to carry out complex opertions
C．early chartered trading companies should be more seriously considered by scholars studying the origins of modern multinationals
D．scholars are quite mistaken concerning the origins of modern multinationals
E．the management structures of early chartered trading companies are fundamentally the same as those of modern multinationals
