第9题

Many of us believe that a person's mind becomes less active as he grows older. But this not true

. According to Dr. Jarvik, professor of psychiatry at the University of California. She had studied the mental functioning of aging persons for several years. For example, one of her studies concerns 136 pairs of twins, who were first examined when they were already 60 years old. As Dr. Jarvik continued the study of the twins into their 70s and 80s, their minds did not generally decline as was expected.

However, there was some decline in their psychomotor (精神运动的) speed. This means that it took them longer to accomplish mental tasks than it used to. But when speed was not a factor, they lost very little intellectual ability over the years. In general, Dr. Jarvik's studies have shown that there is no decline in knowledge or reasoning ability. This is true not only with those in their 30s and 40s, but with those in their 60s and 70s as well.

It is true that older people themselves often complain that their memory is not as good as it once was. However, much of what we call "loss of memory" is not that at all. There usually was incomplete learning in the first place. For example, the older person perhaps had trouble hearing, or poor vision, or inattention, or was trying to learn the new things at too fast a pace. In the cases where the older person's mind really seems to decay, it is not necessary a sign of decay due to old age. Often it is simply as sign of a depressed emotional state.

第10题

At the 1986 Chernobyl nuclear accident, there was a very large release of radioactivity in a few min

utes, followed by a slowly declining release rate over several months. The total release is estimated to have been about 5×10⁷curies The winds carried the released materials all the way to Sweden, from which the first reports came that there had been a nuclear accident in the USSR.

For the purposes of this problem assume that there was an instantaneous release of 10⁷curies of radioactive gases (and fine particles, which are assumed to remain in the atmosphere and not settle out). Then estimate the maximum ground level concentration of radioactive gases (curies/m³) when the radioactive cloud from the accident got to Sweden. Make the following assumptions:

(1) Ignore decay of the radioactive gases (i.e., assume their half-lives were infinite).

(2) Assume the distance between Chernobyl and Sweden is 1000 km.

(3) Assume that the wind speed was 3 m/s and the stability class C.

(4) Assume that the mixing height was 2000 m.

(5) Assume that mlXmg in the x direction(up and down the direction of the wind) has the same intensity as miXing in the y(crosswind)direction.

第11题

In order to show how black people throughout North American were culturally isolated from the start,

it Is important to recognize how strange and unnatural the initial contact with Western society was for the African. Once we realize what a shock this first encounter was, we can begin to understand the amazing albeit agonizing transformation that produced contemporary black Americans from the people who were first bound and brought to this country. Life in colonial America was completely different from what the African thought human existence should be. This was one of the most important aspects of the enslavement of the African, the radically different, even opposing cultural perspectives that the colonial American and the African brought to one another.

Early European-Americans could not appreciate the profundity of the African world view because it differed so greatly from the Western system of thought and ideas. Western culture, which views the ultimate happiness of humanity as the sole purpose of the universe, could not comprehend the goals or “canons of satisfaction” of a culture with elaborate concepts of predetermination and of the subservience of human beings to a complex of Gods. The cruelty of this misunderstanding, when contained within already terrifying circumstance of slavery, should be readily apparent.

Africans were unable to preserve many of the achievements of their civilization under a system of slavery which denied cultural autonomy to the oppressed. European-Americans immediately attempted to eradicate all manifestations of African political, social, and economic traditions. Moreover, the highly developed African system of Jurisprudence could not function under the American form of slavery. Nevertheless, Africans were able to preserve some of their own cultural perspectives, and many of the attitudes, customs, and cultural characteristics of the black American can be traced directly back to Africa. Religion, non-material aspects of

African culture, which could not be suppressed, now form the most apparent legacies of African past.

Because of the violent differences between what was indigenous to their culture and what was forced on them m slavery, Africans developed an eclectic view of the world, containing both those elements of African temperament that could not be suppressed and those elements of Western culture that were essential to survival in North America. Afro-Americans (the first American-born black people, who retained many pure Africanisms ) and later black Americans inherited these cultural complexities and added individual nuances of their own. So, after several generations in the United States, the black Americans developed a separate culture which reflects both their African and their American experience. The African culture, the retention of some parts of this culture in American, and the weight of the step-culture produced a new people.
