（B）
In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."
The city planner decided to build an underground drainage (排水) system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.
An engineer named Ellis Chesbrough convinced me the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.
This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?
That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening. Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.
61. The author mentions the joke to show ______.
62. The city planners were convinced by Ellis Chesbrough to_______.
63. The underlined word "hoist" in Paragraph 4 means "_______".
64. What can we conclude about the moving operation of the Tremont Hotel?
65. The passage is mainly about the early Chicago's ______.
本题为细节推理题，应该根据文章细节信息来推理判断出本题的答案。
根据文章第一段第一句话“In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck”可知芝加哥因为洪水的经常泛滥导致大街上总是泥泞不堪，行人、马和车全都堵在路上。所以作者提及的那个玩笑是为了突出芝加哥的这一特点，故选B。

A;细节推理题。根据倒数第二段中的倒数第二句话：At Pullman’s signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly.(在Pullman的指导下，每个人同时抬起他们手中的千斤顶，因此建筑就被慢慢地、平整地抬起来了)可知A项正确, 故选A

本题为主旨大意题，应该快速通读全文，查找关键词、句，把握文章大意。
文章的第一段就提出芝加哥城所存在的问题，接下来的段落讨论了解决这个问题的一些方法，最后一段讲到这些方法虽然解决当前的问题，但是随之而来的又会冒出一些新的问题有待解决。故文章大致上讲述的是建造的问题与解决办法，故选C
