在美国现代作家杜鲁门.卡波特的作品中塑造了两个出色的女性形象,《蒂凡尼的早餐》里的郝莉和《夏日十字路口》里的格蕾迪,社会阶级、家庭背景以及各自所持的人生观的不同使得这两位少女为着自己想要的人生道路进行着不同的挣扎。然而,结局却是一样的萧条、肃杀。作为卡波特的第一部中篇小说,《夏日十字路口》有着举足轻重的地位,对它的研究可以揭示出卡波特早期作品中业已形成的特定风格及对其成熟作品的影响。 相似文献

Low blood sugar level resulting from fasting has been shown to reduce performance on a number of cognitive tasks. In this study, 80 non-diabetic A-level students missed breakfast. They completed a version of Daneman and Carpenter's Listening Span Test at 9.00 a.m. Half were then given a drink containing glucose, while the other half received a saccharine drink matched for taste. After 20 minutes, both groups completed another form of the Listening Span Test. A subset of the sample had their blood glucose levels determined immediately before the drink and again before the second application of the test. Blood glucose levels did not change, but listening span performance significantly improved after a glucose drink yet not after a saccharine drink. It is concluded that missing breakfast does not seriously affect blood sugar levels in healthy young students, but listening span performance which is a good predictor of listening comprehension is improved when fasting individuals imbibe a glucose-rich drink, although not when a saccharine drink is drunk. Ideally students should eat breakfast, but if this is omitted, then a glucose snack or drink before the first class may reverse any adverse effects. 相似文献

This study was aimed to investigate the relationship between breakfast and serum glucose, insulin and glucagon concentrations in order to establish a model breakfast appropriate for Chinese. Twenty-four volunteers were randomly assigned to four study groups: high carbohydrate breakfast, high fat and protein breakfast, the typical breakfast and fasting. Each subject had serum and urine samples collected while fasting and at 1,2 and 3.5 hours following the meal. The concentration of serum glucose, insulin and glucagon was measured. The levels of serum glucose in group A,B and C differed significantly at 1 and 2 hour after meal compared to those at fasting (P<0.05). The serum glucose in group A increased insignificantly after meal. The serum insulin levels were in group A,B and C significant different compared with control group(P<0.05).Those peaked at 1 hour after meal ,with group C rising the furthest. Compared with the fasting group, the serum glucagons rose and maintained the increase after breakfast in group A,B and C (P<0.05).The data suggested that various diets with different calorigenic amounts increased hormone concentration to various extents. We found that a breakfast rich in carbohydrates could maintain proper blood glucose level. 相似文献
