问题    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 at this level was not in the animals’ best【C1】______ . I remember one midterm exam in【C2】______  each student was handed a large, freshly-killed frog and instructed to dissect (解剖) and mark a set of body parts. I looked at the【C3】______frog in front of me and was saddened that her life was【C4】______  away for such a slight reason.
   A year later, in the same lab where I dissected the frog, I performed a small act of animal operation. We were【C5】______on fruit flies, and it was time to record the distribution of characteristics in their next generation. Flies were kept in small plastic bottles. Counting the number of flies with white or red eyes required first exposing them to ether (乙醚)【C6】______they could not move. The flies were then spread onto a piece of white paper【C7】______and counted. When the data collection was complete, the flies had no further use, and our instructions were to put them into a small glass dish of oil at the center of each desk, which was to be their final resting【C8】______.
   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【C9】______  them.

That was my first step in refusing to conduct scientific research that treated nonhuman life in a (n)【C10】______way.
【C6】
选项 A、while
B、because
C、in case
D、so that
答案D
解析 考查句子逻辑关系。让它们接触乙醚，目的是让它们不能移动。so that引导目的状语从句，意为“为了……”。
