CРОЧНО, ПЕРЕВЕДИТЕ, ПОЖАЛУЙСТА! НЕ ПЕРЕВОДЧИКОМ, ПРОШУУУ!
Saying Tamara Blackmore experienced culture shock when she arrived here last September is an understatement. It was more like culture trauma (extreme form of “culture shock”) for this adventurous student who left Melbourne’s Monash University to spend her junior year at Boston College (BC). Bkackmore, 20, was joined at BC by 50 other exchange students from around the world. Like the thousands of exchange students who enroll in American colleges each year, Blackmore discovered firsthand (learned by directly seeing or experiencing) there is a sea of difference (very big difference) between reading about and experiencing America firsthand. She felt the difference as soon as she stepped off the plane.
As soon as she landed in Boston, Blackmore could feel the tension in the air.
She was about to taste (to experience) a lifestyle far more hectic (very busy) than the one she left. “Driving in Boston is crazy,” says Blackmore. “It took me a while to get used to the roads and the driving style here. I was always afraid someone was going to hit me. It was particularly tricky since the steering wheel was on the wrong side of the car. In Australia, it’s on the right side.” Beyond the cars and traffic jams, Blackmore said it took a while to get used to so many people in one place, all of whom seemed like they were moving at warp speed (traveling very, very quickly).
“There are only 18 million people in Australia spread out over an entire country,” she says, “compared to more than six million people in the state of Massachusetts alone. We don’t have the kind of congestion you have in Boston. There is a whole different perception of space”.
The pressing problem for Blackmore was making a quick adjustment to the American lifestyle that felt like it was run by a stopwatch (a watch which can be started and stopped by pressing a button). For this easygoing Australian, Americans seemed like perpetual – motion machines (machines that never stop moving). “Americans are very time-oriented,” Blackmore says.
