My previous home had a stand of woods behind it and many animals in the backyard. That first year, I 31 feeding peanuts to the blue jays, then the squirrels. The squirrels had no 32 coming up right to me for them.As the months went by, the rabbits saw that I was no 33 and didn’t escape. When I threw carrot slices(薄片), they even came for a nibble(啃). Slowly they came to 34 me, and by the end of the year they were eating out of my hand.
That second year, the rabbits 35 me,and one would even sit up for slices! While I was feeding them, I 36 that a groundhog who used to run away was now taking an 37 interest in this food situation. I carefully extended a long 38 , with a keen eye on those teeth, and 39 , there were times I would have the groundhog sitting next to a rabbit, both munching(津津有味地咀嚼) on carrots. A few months later,while 40 , she would even turn her back to me. 41 when she was facing away, I reached out and 42 scratched(搔) her back with my finger. She didn’t move.
By year three,the rabbits and the groundhog were back.The groundhog 43 didn’t have a problem with me scratching her back,and I got an idea. I’d always 44 , while slicing up carrots, that the end looked like a cap. 45 one day, just to see what she would do, I gently 46 one on top of the groundhog’s head. Again, not a 47 . The next time, I had my camera ready to record what you see here, one of several dozen such pictures. 48 she had a slice to eat, she never 49 the one on her head. It was a fair 50 — I got a pleasure, and she had yet another tasty treat.
