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 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 （螺旋千斤頂） 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.

2．Ever since I graduated from high school I've worked in the factories surrounding my hometown every summer.However，making the transformation between school and full-time blue-collar work during the break never gets any easier.For a student like me who considers any class before noon to be unacceptable，getting to a factory by 6 o'clock each morning is suffering.My friends never seem to understand why I'm so relieved to be back at school or that my summer vacation has been anything but a vacation.
There are few people as self-confident as a college student who has never been out in the real world.People of my age always seem to overestimate the value of their time and knowledge.In fact，all the classes did not prepare me for my battles with the machine I ran in the plant，which would jam whenever I absent-mindedly put in a part backward or upside down.
The most stressful thing about blue-collar life is knowing your job could disappear over night.Issues like being laid off and overseas relocation had always seemed distant to me until my co-workers told me that the unit I was working in would shut down within six months and move to Mexico，where people would work for 60 cents an hour.
After working 12-hour shifts（輪班）in a factory，the other options have become only too clear. "This job pays well，but it's hell on the body，" said one co-worker. "Study hard and keep reading." she added.When I'm back at the university，skipping classes and turning in lazy re-writes seems too irresponsible after seeing what I would be doing without school.All the advice and public-service announcements about the value of an education that used to sound stale（陳腐的）now ring true.
My experiences in the factories have inspired me to make the most of my college years before I enter the real world for good.

3．The size of the British Isles often leads people to think that the languages spoken in its countries of England，Scotland，Wales and Northern Ireland are somewhat the same.At first，visitors are often surprised to find that they have difficulty in understanding the accents and dialects of certain regions.Even in England there are many different dialects.
Experts believe that for most English people，the places they come from are very important to them.Accents are clues to where people were born and where they grew up.Although some people may change the way they speak during their lifetime，most people carry at least some evidence of their accents and dialects throughout their lives.In addition to the regional accents of England，there can also be class differences among the accents.People are often able to make instant and unconscious judgments about a stranger's class by listening to his or her accent.Both the words and the pronunciation of an individual reflect his or her social position.
It is agreed that in England，the kind of English spoken by a person plays a leading role that generally is not important in North America.The importance of accents and their cultural and social relationships are well represented in films and on television in Britain.The film My Fair Lady based on George Bernard Shaw's 1912 play Pygmalion is often said to be a wonderful example of how social class and the accent were，and still are，linked in Britain.
