1.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 12feet.
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 (螺旋千斤頂) beneath the building's foundation.One man was assigned to operate each section of roughly 10jackscrews.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 showB.
A.horses were fairly useful in Chicago
B.Chicago's streets were extremely muddy
C.Chicago was very dangerous in the spring
D.the Chicago people were particularly humorous
62.The city planners were convinced by Ellis Chesbrough toD.
A.get rid of the street dirt
B.lower the Chicago River
C.fight against heavy floods
D.build the pipes above ground
63.The underlined word"hoist"in Paragraph 4means"B".
A.change
B.lift
C.repair
D.decorate
64.What can we conclude about the moving operation of the Tremont Hotel?A
A.It went on smoothly as intended.
B.It interrupted the business of the hotel.
C.It involved Pullman turning ten jackscrews.
D.It separated the building from its foundation.
65.The passage is mainly about the early Chicago'sC.
A.popular life styles and their influences
B.environmental disasters and their causes
C.engineering problems and their solutions
D.successful businessmen and their achievements.

分析 在早期的歷史中,芝加哥經(jīng)常發(fā)生洪水,尤其是在春天,街道變得如此的泥濘不堪以致于人們,馬和車經(jīng)常被困。(dāng)時流行這樣一個古老的笑話:在芝加哥泥濘的街上,一個人的腰被困住了.問他是否需要幫助,他回答說:"不,謝謝.我還有一匹好馬在下面."
    城市規(guī)劃者決定建造一套地下排水系統(tǒng),但只不過沒有地面與水平面之間足夠的高度差,只有兩個選擇即降低芝加哥河的水位或者抬高城市的高度.一個叫埃利斯切斯布羅的工程師說服我該城市除了將管道建在地面上,然后用泥土覆蓋上之外別無選擇,這會使城市的街道提高12英尺之多.
    當(dāng)然這樣會產(chǎn)生一個新的問題:事實上,泥土埋掉了芝加哥幾乎每一棟大樓的第一層.建筑業(yè)主們面臨著一個選擇:要么將建筑物的一樓改到地下室,把第二層改到主樓層,或?qū)⒄麄建筑提升到新的街水平.小的木結(jié)構(gòu)的建筑會相當(dāng)容易地舉起來.但對于像特里蒙特酒店那樣大而重的六層磚混結(jié)構(gòu)的建筑怎么辦呢?
    這里喬治普爾曼派上了用場.他已經(jīng)成功地開發(fā)了一些搬家技巧.提升一個像特里蒙特酒店那樣大的結(jié)構(gòu),鉑爾曼將成千上萬的置于建筑物的地基部.一個人被分配到操作每一段大致10個螺旋千斤頂.在鉑爾曼的指導(dǎo)下,每個人同時抬起同樣數(shù)量的螺旋千斤頂,從而緩慢、均勻地抬起建筑物.令人驚訝的是,在整個運作過程中特里蒙特酒店仍然在營業(yè),很多客人甚至沒有注意到有什么事情發(fā)生.有些人喜歡說,每個問題都有解決的方法.但在芝加哥的早期歷史,每一個工程的解決方案似乎創(chuàng)造著一個新的問題.現(xiàn)在芝加哥的廢水被有效地排放到芝加哥的河里,該城市的下一步就是治理污染的河流.

解答 61-65BDBAC
答案:61.細節(jié)推理題選B 作者提到的這個笑話表明:A 在芝加哥,馬非常有用.B 芝加哥的街道相當(dāng)?shù)哪酀簦瓹 在春天,芝加哥很危險.D 芝加哥的人們尤其的幽默.
     根據(jù)第一段的第一句話  In its early history,Chicago…and carts got stuck.(尤其是在春天,芝加哥經(jīng)常發(fā)生洪水,街道變得如此的泥濘不堪以致于人們,馬和車經(jīng)常被困。宰髡咛岬降男υ捠菫榱送怀鲞@一點即道路的泥濘.) 故選B

      63.細節(jié)推理題 選B 第四段劃線單詞的意思:A 改變 B 舉起,抬起,提升C 修理 D 點綴 根據(jù)后文Small wood-frame buildings could be lifted fairly easily.(小的木結(jié)構(gòu)的建筑會相當(dāng)容易地舉起來.)可知另一種方法就是將建筑升高.故選 B
      64.細節(jié)推理題 選A 關(guān)于特里蒙特飯店的搬遷,我們可以推斷出 A進展的如料想的那樣順利.B它中斷了酒店的生意.C它涉及到普爾曼要用到10個 螺旋千斤頂. D它使地基與建筑物相分離.根據(jù)最后一段的第三句At Pullman's signal…slowly and evenly.(在鉑爾曼的指導(dǎo)下,每個人同時抬起同樣數(shù)量的螺旋千斤頂,從而緩慢、慢慢地抬起建筑物.)可知A正確,故選A
       65.主旨大意題  選C 該段落主要是關(guān)于:A流行的生活方式和影響 B 環(huán)境災(zāi)害與原因 C工程問題及其解決方法 D成功的商人他們的成就 本題為總結(jié)概括全文的主旨大意題,第一段提到芝加哥城所存在的問題,接下來討論了解決這個問題的一些方法,最后一段講到雖然解決了當(dāng)前的問題,但隨之而來又會產(chǎn)生一些新的有待解決的問題.故文章大致上講述的是建造的問題與解決的辦法.故選C.

點評 本文講述了芝加哥城的問題與改造方案,61---64題為細節(jié)推理題,65題為概括主旨大意題.所以在閱讀過程中,首先要泛讀,要快速通讀全文,了解段落的主題;其次要精讀,結(jié)合每題的問題,在文中找到原句進行推理.

Street dances are dance styles that evolved (演變) outside of dance studios in any available open space. They are often improvisational (即興的) and social in nature,encouraging interaction and contact with audiences and the other dancers. These dances generally evolve out of urban and suburban spaces and are a part of the native culture of that geographical area. Some examples of street dances include B-boying, or breakdancing, which originated in New York City, and Melbourne Shuffle which originated in Melbourne, Australia.

Street dances are dances that evolve between people in a social environment,although it cannot be always determined as to how they actually do evolve between people. In theory, as one person comes up with a move that looks good to another person, that other person tries to copy that move. Similar to the game of Chinese Whispers, the effect is that the other person cannot absolutely perform that move the same way as the other person, thus leading to the dancer creating their own style or entirely new moves.

There is a small difference between entirely freestyle dance and an absolute street dance. While freestyle dance is random and a personal dance invented by a single person (even if ifs based on someone else’s dance style), a full street dance is a collection of the various similar dance moves and styles collected into one practice and regarded as the same dance. For example, when B-boying evolved out of early hip-hop culture, people came up with their own moves, and other people improved them. Street dances constantly evolve for as long as they are now and then practiced and regarded as the same dance. All the moves danced to breaks in hip-hop culture were regarded as B-boying.

Sometimes it is possible to trace back street dance styles that were mostly pioneered by specific persons. One example is Locking, which is often regarded as being started by Don Campbell, who was a 1970s pioneer of American street dance. Most of the time it is impossible to owe street dances to specific people; since the dances evolve outside of professional dance environments, and there is no social or legal record. Street dance pioneers also rarely have professional degrees in dance, thus distinguishing street dance from other modern dance forms.

1.Paragraph 1 is intended to tell us the of street dances.

A. varieties B. changes

C. characteristics D. distributions

2.What do we know about street dances?

A. Dancers perform them in dance studios.

B. They are developed by professional dancers.

1.PEOPLE NOBLE SMUGGLER
This Thursday,Irena Sendler will be honoured for her work as a smuggler(偷運者).During World WarⅡ,the Polish social worker smuggled nearly2,500Jewish children out of the Warsaw ghetto(聚居區(qū)).She gave them new identities,found them safe places with good-hearted Christians,and kept the children's real names buried in jars in her neighbours'gardens.(The play,Life in a Jar,based on her story,is being performed.)At 93,Sendler lives in a Warsaw nursing home and is too weak to travel to Washington D.C.,to receive the 2003Jan Karski Award for Valorand Compassion from the American Center of Polish Culture.One of the children she saved will accept the award for her.
You risked your life to save the children.
I was taught by my father that when someone is drowning,you don't ask if they can swim,you just jump in and help.During the war,everyone was drowning,but mostly the Jewish children.

When I saw a priest(牧師)in charge of an orphan age for Jewish children in the ghetto walk with them out to be killed.The children were in then best Sunday suits.The priest was killed with them.
How did you get the children to behave as you smuggled them out?
I told the older children to act as if they were sick and sometimes gave the younger ones a sleeping pill.They were told to remember their new names.I also told the children to tell guards they had only been visiting a servant in the ghetto and were going back to their real homes outside.
Did you tell your own two children what you did?
I never told them.Only when my daughter went to Israel did she learn all about me.I thought it was only normal to do so.And it was a very painful subject.It was always on my mind that I couldn't do more.
--Samantha Levine
