So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births; but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and on the capacity of a man to get along with his fellow citizens. If our educational system were fashioned after its bookless past we would have the most democratic form. of "college" imaginable. Among the people whom we like to call savages all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect everybody is equally equipped for life.
It is the ideal condition of the "equal start" which only our most progressive forms of modem education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no "illiterates"--if the term can be applied to people without a script--while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England 1876, and is still non-existent in a number of "civilized" nations. This shows how long it was before we deemed it necessary to make sure that 'all our children could share in the knowledge accumulated by the "happy few" during the past centuries.
Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents, therefore the jungles and the grasslands know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children and no father is confronted with his inability to "buy" an education for his child.
The word "interest" in the first paragraph most probably means ______.
A．pleasure
B．returns
C．share
D．knowledge
A.AEBDC
B.BDCAE
C.DABEC
D.BEACD

High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．
