The doctor had said there wasn't anything more that could be done, that he should take the Cat home and make him as 32 as possible. The man put the Cat on his lap and 33 .The Cat opened his eyes, purred and looked up at the Man. A tear 34 down the Man's cheek and 35 on the Cat's forehead. The Cat gave him a slightly annoyed look. " Why do you cry, Man?" the Cat asked. "Because you can't 36 the thought of losing me? Because you think you can never replace me?" The Man 37 "yes". "And where do you think I'll be 38 I leave you?" the Cat asked. The Man shrugged helplessly. " 39 your eyes, Man," the Cat said. The Man gave him a questioning look, but did as he was told. "What color are my eyes and fur?" the Cat asked. " Your eyes are gold and your fur is a rich, warm brown," the Man replied. "And where is it that you most often 40 me?" asked the Cat. “I see you. . . on the kitchen window 41 the birds …,on my favorite chair. . . on my desk lying on the papers I need. . . on the pillow next to my 42 at night. " "Then, whenever you wish to see me, all you must do is close your eyes," said the Cat. “Pick up that piece of string from the floor——there, my ‘toy’ .” he Man opened his eyes, then 43 over and picked up the string. It was about two feet long and the Cat had been able to 44 himself for hours with it. '"Now take each end of the string in one hand," the Cat ordered. The Man did so. "The end in your left hand is my birth and the end in your right hand is my 45 . Now bring the two ends together," the Cat said. The Man obeyed. "You have made a continuous 46 ," said the cat. "Does any point along the string appear to be different, worse or better than any other part of the string?" The Man inspected the string and then 47 his head " no". The Man shut his eyes hard as the tears poured down his face. He saw the Cat on the 48 , then in his bed, then lying across his important papers. He saw him on the pillow next to his head, saw his bright gold eyes and darkest brown on his nose and ears. He opened his eyes and 49 his tears looked over at the circle of string he still held in his hand. One day, not long after, there was a new Cat on his lap. She was lovely and white…very different from his earlier 50 Cat and very much the same.

某研究小组对“滑动摩擦力的大小与接触面积、接触面湿度是否有关”的问题进行探究．他们选择了一块各面粗糙程度相同并带有挂钩的长方体物块为研究对象．那么：
（1）实验所用的测量工具除了刻度尺之外还需要_____________．
（2）在测量滑动摩擦力的大小时，必须让物块在水平面上做_____________运动，才能使测出拉力的大小与滑动摩擦力的大小相等．
（3）下表为实验记录表格，通过分析表中序号为________的实验记录．可得到的初步结论是：滑动摩擦力的大小与________无关；表中序号为3、4、5的实验记录，则可说明滑动摩擦力的大小与________有关．
| 序号 | 接触面积S | 接触面干湿程度 | 摩擦力f/N |
| 1 | 小 | 干 | 0.5 |
| 2 | 中 | 干 | 0.5 |
| 3 | 大 | 干 | 0.5 |
| 4 | 大 | 较湿 | 0.6 |
