完形填空。 One day I pulled up to my apartment building and noticed there was a father and daughter __ 1 __ some things from a moving truck. Normally I'm shy away from contact with __ 2 __. That particular day, though, something was in me; I can't explain __ 3 __, but I felt like I should just help these people, even __ 4 __ something as seemingly unimportant as unloading a truck. So I __ 5 __ and introduced myself, welcomed them to the town, and asked them to give me a(n) __ 6 __ to put some proper shoes on. After I had flipflops(夹趾拖鞋)on, I went over and helped them move all of their __ 7 __ into the apartment. After we finished, we talked some and I got to know my new __ 8 __. It might seem unimportant, but it seems like people are less __ 9 __ and friendly to their neighbors these days; I wanted to __ 10 __ that, at least in my small __ 11 __ block. So we did talk,and they're from Florida, just like me. At that __ 12 __ time in my life, I was going through a really difficult __ 13 __ with my girlfriend of 7 years. I didn't feel like helping anyone or doing anything __ 14 __, but I figured why not?And I'm glad I did. Also, as __ 15 __ would have it, their daughter is my age(college student)and we each had a mutual(相互的)__ 16 __in one another. This developed into a friendship, and in the coming months, probably more. The __ 17 __ was the act itself, though. I got to know my new neighbors and made some new friends in the __ 18 __. And I felt really good about it. Since then, I've tried __ 19 __ my comfort zone to perform other unplanned acts of __ 20 __. So far, so good.I'd encourage everyone else to do the same!
