2 . My mother turned ninety. I knew I needed to find a senior _______ center. Not for her — for me. If I were at her age, I would want to stay in shape to _______ life, getting a lot of pleasure. Yes, walking in local parks was my _______, but I wasn’t so active as before.

I called a nearby center, “Do you have aerobics (有氧运动) classes _______ for seniors?” “Sure. Come and check us out! We start at 10 am,” the receptionist (接待员) replied and _______. The next morning, I went there. One part of me was _______ that the class was too easy, not doing me any good. The other part feared it was too hard for me to _______.

When I came into the room, a woman _______ me, “Oh, you’re new. Welcome.” Then the music started. The hour-long workout woke up the muscles I didn’t often _______ in daily walks, suiting me fine. I became a member there. My classmates ranged in age from fifty to ninety. Most gave the exercises their own ________, doing as much or little as they could. ________ no one kept score. Soon I learned physical well-being wasn’t the only ________ there. During breaks, people chatted happily. Whenever some people were ________ we asked around. Were they busy? Were they in hospital? Moreover, we signed cards for those who were ill.

I ________ to be in good shape now as I’ve hoped. Still, I’m grateful for things more valuable from the class — close friendships and new social ________.
