我有更好的答案
(*^__^*) ……你的好评解。亲，记得好评哦：第四题，折射角也增大：选C
光从空气写射入水中：选C
光从空气射入玻璃时，但折射角始终小于入射角，放入射角增大时。第五题，入射角始终大于折射角！如果我的回答对你有帮助，是老师不断答题的动力

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 r occupation and social status were inherited. In American society, however, the class stru 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. Firs although flatboats and keelboats continued to be important until the 1850's steamboats eventually superseded all other craft in the carrying of passengers and freight.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
昨天发错到精品区了T_T捂脸

我理解得也不一定对。我觉得第四题，你说的那句并不能表明D，倒是能表明A。NEED与ESCAPE这两个词有一定推断的意思，而选项A则是这句话的改写，“the desire to move from one place to the next”改写自“ lacked the ties that had bound them and their ancestors to a single place. ”。
第10题我觉得转换的意思更贴切，更多地指把远输的路线从RIVERS转到CANAL，一个SHORTER ROUTE，而并非是把MUCH OF THEIR PRODUCE从RIVERS运到CANAL。所以，CLOSEST MEANING应该是SHIFTED。
一愚之见，欢迎讨论

感谢回复~我还是很难理解啊T_T第六题。A选项我总觉得有种一直搬一直换的意思，而我列的那句话说他们因为这些crisis而想要搬家，不是想要躲避吗？

Many of those who experienced this sharp break thereafter lacked the ties that had bound them and their ancestors to a single place. 这句话我认为说的是，经历过这个SHARP BREAK的人因此上不再像他们的祖辈那样，被束缚在一片固定的土地上。
这样理解的话，他们MOVE FROM ONE PLACE TO NEXT PLACE的这种行为，是因为原来经历过那样政治或宗教的危机之后形成的。那么，这种迁移的行为或习惯，并非是由当前正在进行的宗教或政治的危机驱使所造成的。我认为这里存在一个时间先后的关系。

还有就是，那种因宗教和政治危机而造成迁移，指的是当前这些美国人的祖先，他们的迁移是“ACROSS THE ATLANTIC”，即从欧洲来到美洲，比如当年的PROTESTANT。但本题问的是，从美国东部迁到西部的这些人。所以，不能把本题和宗教与政治危机联系起来。
我也是又看了遍原文，才想到这点的。

托福阅读和GRE阅读最大的不同，我觉得是比较直接。托福阅读所有的题目答案都一定可以在原文中找到对应，比较直接明了的对应。正确答案基本上是原文的改写。所以定位很重要。找到出题点的位置，把前后的东西读明白了，基本上能搞对。
不过也不排除现在的托福题目会变得狡猾，绕个弯儿什么的。但我觉得，真心比GRE阅读好弄很多。版主备考过GRE，搞托福阅读应该是小菜
