Para 1 

句1 I almost go back to sleep before my eye catches my packed suitcase and I groan, remembering that I’m going to the airport.

句2 After all the trouble of this morning, my flight is canceled and I’m stuck in this terminal for the next 218 minutes, and my only consolation is a cup of complimentary airport coffee. 

句3 This is traveling, a burdensome series of running and waiting, and after countless hours, finally getting there. 

Para 2

句4 I don’t mind the actual flying, the wonder of being airborne in a dense metal bird. 

句5 The rest of the journey, however, can feel like a tedious lesson in the ills of modernity, from the predawn x-ray screening to the sad airport malls selling clustersof keepsakes. 

句6 It’s the result of a globalized world, and it sucks.

Para 4 

句7 But most travel is decidedly optional. 

句8 Only corporate travel, about 30 percent of trips over 50 miles, is truly compulsory. 

句9 In most cases, we travel because we want to, because the annoyances of the airport are offset by the thrill of being someplace new. 

句10 Because work is stressful and our blood pressure is too high and we need a vacation somewhere tropical. Because home is boring. Because the flights are on sale. Because Paris is Paris.

Para 5 

句11 Thanks to modern aviation, we can now move through space at an inhuman speed. 

句12 For the first time in human history, we can outrun the sun and move from one hemisphere to another in a single day.

句13 But here’s the irony: Our mind is most likely to solve our most stubborn problems while we are sitting in a Left Bank café. 

句14 So, instead of contemplating that buttery dessert, we should be conscious of those domestic issues we just can’t solve.

Para 6 

句15 The larger lesson, though, is that our thoughts are saturated with the familiar. 

句16 The brain is a space of near-infinite possibility, which means that it spends a lot of time and energy choosing what not to notice. 

句17 As a result, creativity is traded away for efficiency; we think in finite, literal prose, not symbolic verse. 

句18 A bit of distance, however, helps loosen the cognitive chains that imprison us, making it easier to mingle the new with the old; the mundane is grasped from a slightly more abstract perspective. 

句19 According to research, the experience of an exotic culture endows us with a valuable open-mindedness, making it easier to realize that even a trivial thing can have multiple meanings.

句20 Take head movement, which is commonly used to communicate positive versus negative response, as an example. 

句21 In most cultures, nodding one’s head denotes positivity, meaning “yes”, and shaking the head is associated with negativity, meaning “no”.

Para 7 

句22 Such cultural contrasts mean that seasoned travelers are open to ambiguity, willing to realize that there are decidedly different (and equally valid) ways of interpreting the world. 

句23 This, in turn, allows them to expand the circumference of their “cognitive inputs” as they refuse to settle for their first answers and initial guesses. 

Para 8

句24 Of course, this mental flexibility doesn’t come from mere distance, a simple change in latitude and longitude. 

句25 Instead, this renaissance of creativity appears to be a side effect of difference: We need to change cultures, to experience the disorienting diversity of human traditions. 

句26 The same facets of foreign travel that are so confusing (Do I tip the waiter? Where is this train taking me?) turn out to have a lasting impact, making us more creative because we’re less insular.

Para 9

句27 So, let’s not pretend that travel doesn’t have its drawbacks, or that we endure jet lag for pleasure. 

句28 We don’t spend 10 hours lost in the Louvre because we like it, and the view from the top of Machu Picchu probably doesn’t make up for the trouble of lost luggage. (More often than not, I need a vacation after my vacation.) （景点可以找英文文字视频材料做背景拓展）

句29 We travel because we need to, because distance and difference are the secret cornerstones of creativity.
