填空题Translate the following passage into Chinese．(辽宁大学2007研，考试科目：英语专业基础)Every morning was a cheerful invitation to make my life of equal simplicity, and I may say innocence, with Nature herself. I have been as sincere a worshipper of Aurora as the Greeks. I got up early and bathed in the pond: that was a religious exercise, and one of the best things which I did. They say that characters were engraved on the bathing tub of King Tching-thang to this effect, "Renew thyself completely each day: do it again, and again, and forever a-gain. " I can understand that. Morning brings back the heroic ages. I was as much affected by the faint burn of a mos-quito making its invisible and unimaginable tour through my apartment at earliest dawn, when I was sailing with door and windows open, as I could be by any trumpet that ever sang of fame. It was Homer"s Requiem: itself an Iliad and Odyssey in the air, singing its own wrath and wanderings. There was something cosmical about it: a standing advertisement, till forbidden, of the everlasting vigor and fertility of the world. The morning, which is the most memorable season of the day, is the awakening hour. Then there is least somnolence in us: and for an hour, at least, some part of us awakes which slumbers all the rest of the day and night.

填空题A rapid means of long-distance transportation became a necessity for the United States as settlement spread ever farther westward. The early trains were impractical curiosities, and for a long time the railroad companies met with troublesome mechanical problems. The most serious ones were the construction of rails able to bear the load, and the development of a safe, effective stopping system. Once these were solved, the railroad was established as the best means of land transportation. By 1860 there were thousands of miles of railroads crossing the eastern mountain ranges and reaching westward to the Mississippi. There were also regional southern and western lines. The high point in railroad building came with the construction of the first transcontinental system. In 1862 Congress authorized two western railroad companies to build lines from Nebraska westward and from California eastward to a meeting point, so as to complete a transcontinental crossing linking the Atlantic seaboard with the Pacific. The government helped the railroads generously with money and land. Actual work on the project began four years later. The Central Pacific Company, starting from California, used Chinese labor, while the Union Pacific employed crews of Irish laborers: The two groups worked at remarkable speed, each trying to cover a greater distance than the other did. In 1869 they met at a place called Promontory in what is now the state of Utah. Many visitors came there for the great occasion. There were joyous church bells to honor the great achievement. The railroad was very important in encouraging westward movement. It also helped build up industry and farming by moving raw materials and by distributing products rapidly to distant markets. In linking towns and people to one another it helped unify the United States.
