假设有人给了你一枝笔,一枝密封的、纯色的水笔,里面有多少墨水你看不到,很可能刚刚试写几字便用干耗尽;也可能足以完成一部或几部杰作,永存于世,使世事为之大变。而这一切你在动笔之前却是一无所知。根据游戏的规则,你确实水远也不会知道,只能冒一下险。而事实上,也没有  相似文献

箭与歌     
我向空中射出一枝箭,我不知它落在何方。因为它飞得如此神速,我的视力都追赶不上。我向高空唱出一支歌,我不知它落在何方。谁有如此犀利眼力,能追赶上歌声的飞扬?  相似文献

Based on an evolutionary theory of socialization, Belsky and colleagues proposed that girls exposed to a stressful environment, especially when due to father absence in the first 7 years of life, showed an early onset of puberty, precocious sexuality, and unstable relationships as adults. The authors of this article examined an alternative explanation that a variant X-linked androgen receptor (AR) gene, predisposing the father to behaviors that include family abandonment, may be passed to their daughters causing early puberty, precocious sexuality, and behavior problems. The results of a study of 121 White males and 164 White females showed a significant association of the short alleles of the GGC repeat polymorphism of the AR gene with a range of measures of aggression and impulsivity, increased number of sexual partners, sexual compulsivity, and lifetime number of sex partners in males; and paternal divorce, father absence, and early age of menarche in females. These findings support a genetic explanation of the Belsky psychosocial evolutionary hypothesis regarding the association of fathers' absence and parental stress with early age of onset of menarche and early sexual activity in their daughters. A genetic explanation of the father absence effect is proposed in which fathers carrying the AR alleles are more likely to abandon a marriage (father absence) and pass those alleles to their daughters in whom they produce an earlier age of menarche and behavioral problems.  相似文献

A project in Sri Lanka sponsored by USAID AND the Overseas Education Fund (OEF) used nonformal training to prepare development workers to help women's groups orgnize income-generating projects. OEF and the Women's Bureau developed a 2-phase program for a toatl of 2 months training, which was separated by a 5-month period of field work. By the time the project came to an end in June 1982, development officers had helped rural women set up 2000 income-generating activities in Sri Lanka. their net profit was US $32,000 per month or an average of US $16 per woman. The profits from their activities surpassed the cost of the training project in less than a year. In the following year another 2000 activities were successfully started, so that beneficiaries, as of June, 1983 totalled over 22,000 people--4000 rural wmen and their families. The project, therefore, had a positive impact in a variety of areas: increased agricultural population, increased employment, increased participation of women in economic activities, development of institutional capability in rural areas, raised income of the rural poor and enhancement of health and nutrition.  相似文献

College and university requirements for undergraduate deaf education teacher preparation programs from 1986 and 2006 were compared. Thirty percent fewer undergraduate programs were in existence in 2006 than in 1986. Compared to programs in the 1986-1987 academic year, programs in 2006-2007 placed less emphasis on course work related to speech and hearing and more emphasis on the development of sign language skills. These findings are discussed in relation to the increasing probability that future employment for program graduates will be in itinerant and resource placements within public schools with children whose hearing losses are less severe than those of children in the past.  相似文献

文化的核心     
在中国,英语专业的学生通常要学很多门"外国文化"课,学得最多的是英国和美国文化概况.如今,不管是谁,只要对此加以关注,就不应该仅仅认识到文化课所传递信息的重要,更应该能明确列举出开设这些课所要达到的目标.  相似文献
