| It is generally believed that the
greatest damage of old age is the loss of mental faculties. With the near
doubling of life expectancy in the past century has come a mixed blessing. A few
great thinkers and artists remained productive in their later years—Galileo,
Monet, Shaw, Stravinsky, Tolstoy—but even they were not what they bad been in
their primes. In sciences, the boom falls sooner still: "A person who has not
made his great contribution to science before the age of 30 will never do so,"
said Einstein. Imagine if we could transplant old brains into younger bodies: would our minds stay young, or would we be senile teenagers, scaling mountains and skateboarding at 120, but forgetting where we put the car’s keys. Is the brain uniquely vulnerable to the ravages of time Can anything be done Indisputable evidence fr A. higher levels of education are related to greater mental awareness in young age B. higher levels of’ education are irrelevant to lower levels of mental decline in old age C. a higher level of education is the exclusive factor that can slow the rate of mental decline D. less mental activity in life can probably result in higher cognitive losses in old age.

[单项选择]As in the U.S., the recession in Japan springs from the go-go days of the 1980s. From January 1985 to December 1989, the Nikkei stock average shot up from 13,136 to 38,915, fattening Japanese stock collections with tremendous paper profits. At the same time, the real estate market was so hot that corporate land holdings were typically more valuable than the factories built on them. And since 59% of all Japanese own their own homes, the great sharp increases in real estate values made nearly everyone feel wealthier. Many companies and some individuals began to borrow vast sums of capital for expansion, using their stock or real estate investments as collateral(抵押品).
Cheap cash also allowed Japanese companies to fund costly research into technologies like semi-conductors and liquid crystal displays that weren’t likely to bring returns for many years to come.
