次の英文を読んで、以下の設問に答えなさい。

Today was not the best of mornings to ride my bike to work. It was humid and overcast, cool enough that I chose not to wear shorts (my usual commuting wear during the summer months), but still humid enough that my jeans were sticking to my legs by the time I arrived at Friends University, my destination, about 25 minutes later. It could have been worse, of course; it could have been raining. In some ways, I actually prefer the rain when I'm riding in the warm, creeping dampness that you so often experience on cloudy days. A real downpour can make navigating city streets and sidewalks a little tricky, but a good clean, moderate rainfall has never caused me any serious navigation trouble. Besides, the $\fbox{38}$ it can bring is refreshing, especially in contrast to those days when the moisture in the air seems to surround you with a stale stillness, no matter how fast you're moving. Still, I rode my bike, as I do most days when there isn't ice on the streets or I don't have an appointment that requires me to travel to the other side of Wichita. I was happy to do so.

On the best days – and $\fbox{39}$much as I like autumn, my favorites are hot, cloudless, blue-skied summer ones in July, bright days where the horizon on all sides of you lays revealed - my ride to work and home again is a quiet delight, a stream of reminders from my senses with every rotation of my wheel of the world of $\fbox{40}$ and human deeds (good and bad) around me. But even on not so good days - like this morning - I mount my Trek 7100 to make my six - mile journey and don't give it much of another thought. It has become habitual for me. There is no need to give it much thought, because $\fbox{41}$$\fbox{42}$$\fbox{ }$$\fbox{43}$$\fbox{ }$ myself, pretty much every morning and evening during the work week, is the time I get to keep my thoughts completely to myself. I am not thinking about refilling the gas tank, I am not thinking about changing the oil, I am not thinking about how the jerk in front of me is slowing down just when I need to change lanes so that I don't miss my exit; on the contrary. I am thinking about whatever strikes my $\fbox{44}$, or about nothing memorable at all, because my bicycle - my relatively simple locomotion machine – is capable of getting me to $\fbox{45}$ I need to be without obliging me to deal with complex realities. It is slower than commuting by car, of course, but that slowness itself gives me the opportunity to let my mind wander over the day ahead of me or the day just past, let my eyes wander over the world around me - both its busy parts and the parts which remain still - without having lost anything in the meantime. Issues of $\fbox{46}$ need not plague me. After all, I've already unplugged myself from the oil economy more than most people in Wichita: I'm riding a bike.
