By the time I finished high school, my interest in animals had grown, and enrolled at a university to study biology.l 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   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 may 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.56 A at           B  with             C  for             D  off57 A duties         B interests        C rates          D hobbies58 A what           B that             C where          D which59 A dismissed      B drawn            C instructed     D mended60 A alive          B dead             C living         D wounded61 A made           B brought          C taken          D passed62 A reason         B spirit           C space          D system63 A that           B which            C what           D where64 A operation      B liberation       C tendency       D wealth65 A experimenting  B strengthening    C stimulation    D substituting66 A solved         B soaked           C recovered      D kept67 A while          B because          C in case         D so that68 A being examined B to be examined   C being operated D to be operated69 A preliminary    B progressive      C complete       D curious70 A put            B raise            C rouse          D spoil71 A shade          B shadow           C place          D stuff72 A for            B with             C at             D on73 A stood         B took             C sent           D rode74 A step           B review           C glance         D gesture75 A kind           B generous         C cruel          D effective
