W:Hey, Mike!Did you attend Mr.Johnson’s seminar on the History of Chicago?
M:Yes, I did. I didn’t notice you were there, too.
W:I was late for it Wasn’t it a great seminar? I have learned so much!
M:It certainly was. hadn’t understood that Chicago was such a young city, less than 200 years old.
W:Yes, I thought it was an old city before, but it turned out that I was wrong. You still remember what Mr.Johnson said? The army fort, Fort Dearborn, was built in 1803 in the place that would become Chicago. Chicago didn’t officially become a town until 30 years later, in 1833.
M:Yes, and when it officially became a town in 1833, it was very small. It had a population of only 350. Think about that, only 350 people!It was really a tiny town by then.
W:But it’s a pity that after Chicago had grown, much of it was destroyed in a fire. Just imagine!What a big fire it was!
M:The Great Chicago Fire was in 1871. Chicago wasn’t even forty years old at the time, but it had grown much bigger.
W:Yet only twenty-two years later, in 1893, Chicago was able to host a World’s Fair. It was such a huge development for a city.
M:Yes. Chicago had been rebuilt after the fire and was eager to show itself off to the rest of the world at the World’s Fair in 1893.
W:I will attend another seminar on the Economy of Chicago next week. Mr.Johnson will talk about the economy specifically. Will you be there too?
M:Yes, so I will see you next Thursday.
