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 本文介紹了John Wesley Powell（約翰•威斯利•鮑威爾），這位美國(guó)著名的西部探險(xiǎn)家．小時(shí)候的鮑威爾師從科學(xué)家George Crookham，接受了廣泛的非正式的教育，掌握了大量的自然科學(xué)知識(shí)．一有可能，就開(kāi)展自己的科學(xué)之旅．1861年，美國(guó)內(nèi)戰(zhàn)爆發(fā)，鮑威爾參戰(zhàn)，失去了右臂．盡管身有殘疾，卻在1869年開(kāi)始了他著名的科羅拉多河探險(xiǎn)．這一探險(xiǎn)是美國(guó)歷史上最偉大的探險(xiǎn)之旅之一，其艱難令人難以想象，他的許多觀點(diǎn)遠(yuǎn)遠(yuǎn)超越了他所處的時(shí)代．

66．B 推理判斷題．根據(jù)第一段第二句…h(huán)is 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．"小時(shí)候，他師從科學(xué)家 George Crookham，接受了廣泛的非正式的教育．儲(chǔ)備了大量的自然科學(xué)知識(shí)…一有機(jī)會(huì)就開(kāi)始自己的科學(xué)之旅．"以及下文中…h(huán)e began his famous exploration of the Colorado River on May 24 1869"于1869年開(kāi)始了著名的科羅拉多河探險(xiǎn)"，可知，正是他少年時(shí)期接受的科學(xué)教育對(duì)他日后的成長(zhǎng)產(chǎn)生了重要的影響，成就了他美國(guó)著名的西部探險(xiǎn)家美譽(yù)．故選B．
67．C 細(xì)節(jié)理解題．根據(jù)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，年輕的 John 對(duì)自然科學(xué)很感興趣，而他的父親則希望他學(xué)習(xí)宗教．從而導(dǎo)致他們之間的爭(zhēng)執(zhí)持續(xù)了3年之久．故選C．
68．C 推理判斷題．根據(jù)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，雖然，
John身有殘疾，但是他還是取得了自己輝煌的成就--著名的1869年科羅拉多河探險(xiǎn)．身殘志堅(jiān)，有決心，有勇氣．故選C．
69．B 段落大意題．根據(jù)第三段的開(kāi)頭主題句…one of the greatest trips of discovery in the history of America…far more dangerous than expected．"美國(guó)歷史上最偉大的發(fā)現(xiàn)之旅之一…其難度難以想象"可知，這段主要講述鮑威爾探索的重要性和困難．故選B．
70．D 細(xì)節(jié)理解題．根據(jù)第三座最后一句Powell'S explorations led to the creation of US Geological Survey…可知，選項(xiàng)D正確lead to=cause．故選D．

點(diǎn)評(píng) 細(xì)節(jié)理解題需要根據(jù)題干中的關(guān)鍵詞提示，到原文中去找尋相關(guān)的信息；推理判斷題需要在找到文中相關(guān)語(yǔ)句的基礎(chǔ)上，推理判斷字里行間隱藏的信息．
