向大家请教TPO20西迁中的第4题和第10题，谢谢~~
Why were these hundreds of thousands of settlers-most of them farmers, some of them artisans-drawn away from the cleared fields and established cities and villages of the East? Certain characteristics of American society help to explain this remarkable migration. The European ancestors of some Americans had for centuries lived rooted to the same village or piece of land until some religious, political, or economic crisis uprooted them and drove them across the Atlantic. Many of those who experienced this sharp break thereafter lacked the ties that had bound them and their ancestors to a single place. Moreover, European society was relatively stratified; occupation and social status were inherited. In American society, however, the class structure was less rigid; some people changed occupations easily and believed it was their duty to improve their social and economic position. As a result, many Americans were an inveterately restless, rootless, and ambitious people. Therefore, these social traits helped to produce the nomadic and daring settlers who kept pushing westward beyond the fringes of settlement. In addition, there were other immigrants who migrated west in search of new homes, material success, and better lives.第四题：4.According to paragraph 2, all of the following are reasons why Americans migrated westward EXCEPT
O the desire to move from one place to the next
O the hope of improving their socioeconomic status
O the opportunity to change jobs
O the need to escape religious or political crises
请问The European ancestors of some Americans had for centuries lived rooted to the same village or piece of land until some religious, political, or economic crisis uprooted them and drove them across the Atlantic.
这句话哪里体现出了A呢？
另外Many of those who experienced this sharp break thereafter lacked the ties that had bound them and their ancestors to a single place.不是对应D吗？
第10题：Two other developments presaged the end of the era of turnpikes and started a transportation revolution that resulted in increased regional specialization and the growth of a national market economy. First came the steamboat; although flatboats and keelboats continued to be important until the 1850's steamboats eventually superseded all other craft in the carrying of passengers and freight. Steamboats were not only faster but also transported upriver freight for about one tenth of what it had previously cost on hand-propelled keelboats. Next came the Erie Canal, an enormous project in its day, spanning about 350 miles. After the canal went into operation, the cost per mile of transporting a ton of freight from Buffalo to New York City declined from nearly 20 cents to less than 1 cent. Eventually, the western states diverted much of their produce from the rivers to the Erie Canal, a shorter route to eastern markets.
10.The word "diverted" in the passage is closest in meaning to
O collected
O shifted
O transported
O sold
我无法理解C为什么不对？transport不是运输的意思吗？从A地运到B地不是也可以吗？
我知道divert是转换的意思，但是找不到C为什么不对的理由，只要带入原文很贴切就可以选的吧 我认为第四题正确答案是A，第十题选B 前面一题你说的d选项的主语是ancestor of americans 因为祖先经历了sharp experience 所以西迁的美国人要想去其他地方 因为他们不再被bound to a single place
