7 阅读理解。 A middle-aged stranger visited us late on a dark rainy night when my father was working the night shift (a job for a period during the night). The stranger asked if he could wait under the eaves of our roof for the rain to stop. Then he disappeared, and we started hearing footsteps and creaking boards in the attic (the space or room at the top of a building, under the roof, often used for storing things). Was the stranger inside our house? My whole body couldn"t help but stiffen. In my mind"s eye, I could imagine the stranger pushing through the attic door and approaching US. We immediately called Jerry, our neighbor, for help. He searched everywhere, but the visitor was nowhere to be found. As Jerry looked in the garage, he found the stranger lying underneath the car. Jerry exclaimed with fright, "You are not allowed to enter the house. Get off the property right now." We were determined to leave the house immediately. As we drove away, we saw the man blocking our way on the road and staring at us. We had to change the direction to avoid meeting him. After that, I never saw the stranger again. 1.
