On Thursday Mrs.Clarke locked the door and went to the women’s club as usual.
When she came home she sensed __61__ unusual.Had someone got in?The back door and the windows were all locked and there was __62__ sign of forced entry.Had anything been taken?She went from room to room checking and __63__ (find) her spare camera missing.
The following Thursday she went out at her usual time,but she just took a short walk in a park nearby,came home through the back door and settled down to wait and see what __64__ (happen).
It was 4 o’clock __65__ the front doorbell rang.Mrs.Clarke was making tea at the time.The bell rang again,and then she heard her letter-box __66__ (push) open.Picking up the kettle of boiling water,she moved quietly towards the door.A piece of __67__ appeared through the letter-box,and then a hand.__68__ wire turned and caught around the knob （圆钮）on the door-lock.Mrs.Clarke raised the kettle and poured the water __69__ the hand.A sharp cry was heard outside as the wire fell to the floor and the hand was __70__ (instant) pulled back,which was followed by the sound of running feet.

61.very 填副词,根据句意,感觉非常不正常.
62.not sign of .迹象 根据句意,没有武力进入
63.finding and 是并列连词,与checking词性相同
64.happened just took 用一般过去式
65.that 强调句型
66.had pushed letter-box 与push是被动关系,heard 用过去完成时had done
67.knob 下文中出现 knob
68.The 此处填冠词,根据句意,是特指
69.into pour...into...,把...流进...,
70.instanted,and 是并列连词 ,was heard 时态一样
再问： 正确答案
61. something 62. no 63. found 64. would happen 65. when 66. being pushed 67. wire
68. The 69. over/on 70. instantly
