Partly  Cloze (10%)

     By the time I finished high school, my interest in animals had grown, and I enrolled at a university to study biology. I learned soon enough that studying animals 56  this level was not in the animals’ best  57. I remember one midterm exam in 58 each student was handed a large, freshly-killed frog and  59  to dissect (解剖)and mark a set of body parts. I looked at the  60  frog in front of me and was saddened that her life was  61  away for such a slight 62.

     A year later, in the same lab 63 I dissected the frog, I performed a small act of animal 64. We were 65 on fruit flies, and it was time to record the distribution of characteristics in their next generation. Flies were  66  in small plastic bottles. Counting the number of flies with white or red eyes required first exposing them to ether (乙醚)  67  they could not move. The flies were then spread onto a piece of white paper  68  and counted. When the data collection was 69 , the flies had no further use, and our instructions were to 70  them into a small glass dish of oil at the center of each desk, which was to be their final resting 71.

     Once my little pile of flies had been counted, I pushed them off the edge of the paper. As we recorded our data, I kept one eye 72 them. Within minutes the pile was humming (嗡嗡叫) as tiny legs and wings beat their way out of the ether fog. I was extremely excited as they 73 flight. That was my first 74 in refusing to conduct scientific research that treated nonhuman life in a(n)  75  way.
