Question

18．John Wesley Powell（1834-1902）Was a famous explorer of the American West．When he Was young，his mother put him under the guidance of George Crookham，a self-taught scientist，from whom he received a wide，but informal，education．Young John learned many things about the natural sciences．But his father preferred him to study religion．The argument continued for three years．Then John decided to leave home to seek further education．He soon discovered that he knew more about science than any teacher he met．He realized that the only good scientific education in the country came from colleges in the east，like Harvard and Yale．But he Was too poor to go to them，SO he got work as a school teacher in Illinois．Whenever possible，he went on scientific trips of his own．  
In 1861，civil war broke out in the United States．John joined the Union forces of the North．At the battle of Shiloh Powell lost his right arm．Despite his disability，he began his famous exploration of the Colorado River on May 24 1869．
It Was one of the greatest trips of discovery in the history of America．Never before had any white men traveled to that area．The trip Was far more dangerous than expected．The rivers were filled with rocky areas and waterfalls．Sometimes，the boats overturned or broke into pieces against big rocks．All along the way，Powell measured distances，temperatures，heights，depths and currents．He examined soils，rocks and plant life．Powell'S explorations led to the creation of US Geological Survey，which became responsible for all mapping and scientific programs of American lands．
Powell's scientific studies of western lands shaped his ideas of how those lands should be used．He suggested programs to control both crop farming and cattle raising．He Was especially concerned about water supplies．Many of his ideas were rejected at first and were not signed into law until years after his death because they were far ahead of his time．

Answer 1

分析 本文介绍了John Wesley Powell（约翰•威斯利•鲍威尔），这位美国著名的西部探险家．小时候的鲍威尔师从科学家George Crookham，接受了广泛的非正式的教育，掌握了大量的自然科学知识．一有可能，就开展自己的科学之旅．1861年，美国内战爆发，鲍威尔参战，失去了右臂．尽管身有残疾，却在1869年开始了他著名的科罗拉多河探险．这一探险是美国历史上最伟大的探险之旅之一，其艰难令人难以想象，他的许多观点远远超越了他所处的时代．

66．B 推理判断题．根据第一段第二句…his mother put him under the guidance of George Crookham，a self-taught scientist，from whom he received a wide，but informal，education．Young John learned many things about the natural sciences…Whenever possible，he went on scientific trips of his own．"小时候，他师从科学家 George Crookham，接受了广泛的非正式的教育．储备了大量的自然科学知识…一有机会就开始自己的科学之旅．"以及下文中…he began his famous exploration of the Colorado River on May 24 1869"于1869年开始了著名的科罗拉多河探险"，可知，正是他少年时期接受的科学教育对他日后的成长产生了重要的影响，成就了他美国著名的西部探险家美誉．故选B．
67．C 细节理解题．根据第一段第三句Young John learned many things about the natural sciences．But his father preferred him to study religion．The argument continued for three years．可知，年轻的 John 对自然科学很感兴趣，而他的父亲则希望他学习宗教．从而导致他们之间的争执持续了3年之久．故选C．
68．C 推理判断题．根据第二段最后一句Despite his disability，he began his famous exploration of the Colorado River on May 24 1869．可知，虽然，
