题干二、阅读理解：选择题（每题10分） Among the more colorful characters of Leadville's golden age were H.A.W. Tabor and his second wife, Elizabeth McCourt, better known as “Baby Doe”. Their history is fast becoming one of the legends of the Old West. Horace Austin Warner Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. “Great deposits of lead are sure to be found here.” he said. As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco.『It was his custom to “grubstake” prospective miners, in other words, to supply them with food and supplies, or “grub”, while they looked for ore, in return for which he would get a share in the mine if one was discovered. He did this for a number of years, but no one that he aided ever found anything of value. Finally one day in the year 1878, so the story goes, two miners came in and asked for “grub”. Tabor had decided to quit supplying it because he had lost too much money that way. These were persistent, however, and Tabor was too busy to argue with them. “Oh help yourself. One more time won't make any difference,” He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in return for which they gave Tabor a one-third interest in their findings. They picked a barren place on the mountain side and began to dig. After nine days they struck a rich vein of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the “Pittsburgh Mine,” made 1 300 000 for Tabor in return for his $17 investment. Later Tabor bought the Matchless Mine on another barren hillside just outside the town for $117 000. This turned out to be even more fabulous than the Pittsburgh, yielding $35 000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor, and later became lieutenant governor of the state. 操作提示：通过题干后的下拉框选择题目的正确答案。 1. Leadville got its name for the following reasons EXCEPT 回答ABC未回答正确答案是：C获得10.00分中的0.00分.

Other colorful characters.反馈解析： 1. 细节题。因为Leadville可以为Tabor带来巨富。这一点不是Leadville得名的原因，因为在文章第二段中，讲到这一点时，提及三个原因：A.因为Tabor成为当地的居民代表人物，B.因为在Leadville有丰富的铅的储藏量。唯独C没有，因为到后来发现是银矿才给他带来巨富。 2. 词汇题。第二段中grubstake的词义与C所述内容是相同的，即“供给探矿者资金，衣物，食品以及其他物品”。但此处还补充地讲，作为回报，供给者可以获得矿中资源一定份额。(见文章第二段第4行) 3. 细节题。Tabor第一次真正发财是他为两名矿工提供资助，为此他获得他们矿资源三分之一的股份。见文章第三段4-9行内容：两名开矿者从Tabor那儿借走价值17美元的物品，作为回报，Tabor获得他们矿资源三分之一股份。于是两位开矿者在一座山旁的不毛之地开始挖掘，九天之后，发现了银的富矿，于是Tabor又将两人的股份全买下，这样，银矿属于Tabor一个人所有，这个矿就是后来著名的“匹兹堡”矿。Tabor用17美元的投资换来了130万美元的收获。 4. 推断题。由原文可知泰勃的财产来源是有一定偶然性的，但是毕竟也是基于他开创的“grubstake”模式，因为A不对，C更是没有根据，因为他还没有娶第二位夫人这一切就发生了。分析泰勃的做法，会得出B选项所示的结论。 5.推断题。如果本文是一篇文章的第一部分，那么在文章的第二部分将介绍谁呢?key可以从文章第一句分析出来，在Leadville的黄金年代，其多彩的特点当中，Tabor及其第二任妻子Elizabeth McCourt是值得大书特书的，接着，文章都在讲述有关H.A.W. Tabor发家致富的历史，如先买下匹兹堡矿，后又买下Matchless矿，最后成为市长，代理州长，等等，所以涉及到的全是男主人公，因此下边再讲的话，应成为女主人公即Elizabeth McCourt的天地了，她是Tabor的第二任妻子。这是顺理成章的事。人文英语3
