Fire and WaterShundagarh is a village on India’s east-facing coast. It is a village of simple mud and grass houses built on the beach just above the water-line. The Khadra Hills rise immediately behind the village, to a height of one hundred and fifty meters. A simple, good-hearted old man, whose name was Jalpur, farmed two small fields on the very edge of these hills, overlooking Shundagarh. From his fields he could see the fishing-boats that travelled up and down the coast. He could see the children playing on the sand; their mothers washing clothes on the flat stones where the Shiva River flowed into the sea; and their fathers landing the latest catch or repairing nets and telling stories that had no end.All Jalpur owned in the world were the clothes he wore day in and day out, the miserable hut that he slept in at night, a few tools and cooking pots—and his fields. The corn that he grew was all that made life possible. If the weather was kind and the harvest was good, Jalpur could live happily enough—not well, but happily. When the sun was fierce, and there was little or no rain, then he came close to the line between a life which was too hard, and death itself.Last year the weather had been so kind, and the harvest promised to be so good, that Jalpur had been wondering whether he could sell all that he had and live with his son farther up the coast. He had been thinking about doing this for some years. It was his dearest wish to spend his last days with his son and his wife and children. But he would go only if he could give; he would not go if it meant taking food out of the mouths of his grandchildren. He would rather die hungry than do this.On the day on which Jalpur decided that he would harvest his corn, sell it, and move up the coast, he looked out to the sea and saw a huge wave, several kilometres out, advancing on the coast and on the village of Shundagarh. Within ten minutes everyone in Shundagarh would be drowned. Jalpur would have shouted, but the people were too far away to hear. He would have run down the hill, but he was too old to run. He was prepared to do anything to save the people of Shundagarh, so he did the only thing that he could do: he set fire to his corn. In a matter of seconds the flames were rising high and smoke was rising higher. Within a minute the people of Shundagarh were racing up the hill to see what had happened. There, in the middle of his blackened cornfield, they found Jalpur; and there they buried him.On his grave, they wrote the words: Here lies Jalpur, a man who gave, living; a man who died, giving. It was Jalpur’s ambition to()

A. live an easy life in the village of Shundagarh
B. sell his corn and go to live with his son and his family
C. live farther along the coast where the weather was kinder
D. spend a few days with his wife and son on the coast

During the summer session these will be a revised schedule of services for the university community. Specific changes for intercampus bus services, the cafeteria, and summer hours for the infirmary (医务室) and recreational and athletic facilities will be posted on the bulletin beard outside of the cafeteria. Weekly movie and concert schedules which are in the process of being arranged will be posted each Wednesday outside of the cafeteria.Intercampus buses will leave the main hall every hour on the half hour and make all of the regular stops on their route around the campus. The cafeteria will serve breakfast, lunch, and early dinner from 7 a. m. to 7 p. m. during the week and from noon to 7 p. m. on weekends. The library will maintain regular hours during the week, but shorter hours on Saturdays and Sundays. The weekend hours are from noon to 7 p. m..

张颖清教授早在1972年就开始了他的全息生物学研究。经过近20年的深入观察和研究,张颖清发现,无论是植物的枝条、叶片,还是动物的节肢、器官,都是全息胚。每个全息胚都含有生物整体的信息。一切生物体都是由全息胚组成。“全息”一词来源于激光照相,由激光感光后的底片,将其打碎后任何一块小的碎片仍能显示出物体完整的影像来。张颖清教授即是用这一物理现象来比喻生物体整体与局部的关系。全息胚理论的提出,是自300多年前科学家借助显微镜发现细胞以来的又一次重大突破,不仅为观察研究生物界提供了一种全新的方法,加深了人们对生物体的认识,而且还有着广泛的实用价值和重要的理论意义,如农业、牧业、园艺等领域运用全息胚学说,获得增产及品种优化。在医学方面,全息胚学说不仅为中国传统的中医疗法找到了现代科学的理论基础,而且为现代医学提供了一种思路全新的诊疗法,即生物全息疗法或全息胚诊疗法。根据全息胚学说,人体的每一个高发育程度的全息胚都是整个人体的缩影。这样,在每一个长骨节肢这样的全息胚上就有着对应全身各部位的穴位系统,即全息胚穴位图谱。如果人体有某个病理反应。因此,根据病理反应的穴位,也就可以准确判断出人体生病的部位。如果对全息胚上有病理反应的穴位进行针刺按摩或其他刺激,整个人体就会产生特定的生化物质,使各个全息胚上的病理反应穴位和生病部位都得到调整和修复,从而恢复正常的生理功能。这样,疾病就得到了治疗。 全息胚理论是对()学科的研究。

A. 生理及医学
B. 物理学
C. 光学
D. 胚胎学
