When a woman took the seat beside me on a plane, I felt uncomfortable. She had to lower herself slowly, trying her best to fit into the small space.
“My name is Kelly. I’m from Canada. Where are you from?” she said as she waved to me.
“China,” I said as I shook her hand reluctantly（不情愿地）. Kelly kept talking with me. She was very kind. When we were served drinks and meals, she made sure that I had enough room in my seat.
“I don’t want to make you uncomfortable with my elephantine size!” she said sincerely. I couldn’t help but let down my guard（戒备）.
As we talked, I was surprised by her words. She had read many books and was really smart. I asked her, “Have you ever thought about losing some weight?” “Aren’t you worried about health problems because of being overweight?”
“Not at all. I eat healthily and often do sports,” she said. “I believe in my heart that people with illnesses tend（倾向于）to worry. You see advertisements from exercise centres that read, ‘Free yourself from your extra baggage, so you are free to be yourself.’ You’re free only if you’re comfortable with who you are!”
I suddenly understood that Kelly was the most beautiful and clever woman I had ever met in my life.

31. B 根据“She had to lower herself slowly, trying her best to fit into the small space.”及后文Kelly自称elephantine size可知，作者最初不适是因为邻座女士体型较大。故选B。
32. C 根据“Kelly kept talking with me. She was very kind.”及“...she said sincerely. I couldn’t help but let down my guard.”可知，作者放下戒备是因为Kelly的友善和真诚。故选C。
33. B 根据广告语Free yourself from your extra baggage及上下文关于体重、健身的话题可知，extra baggage在此比喻“多余的体重”。故选B。
34. A 根据“I believe in my heart that people with illnesses tend to worry.”可知，Kelly认为疾病往往源于过度忧虑，而不是体重本身直接导致疾病。故选A。
35. D 全文通过作者对Kelly态度的转变，传达了“接纳自我、不以貌取人”的核心信息。故选D。
